Análisis de la coordinación motora por Índice de Masa Corporal y sexo en escolares de Chile

La investigación tuvo como objetivo analizar la relación entre la Coordinación Motora (CM) con el Índice de Masa Corporal en escolares chilenos de entre 7 y 9 años. El estudio fue observacional de corte transversal, con características descriptivas y correlacionales. Se evaluaron a 180 escolares (90 mujeres de 8.4 ± 0.9 años y 90 hombres de 8.5± 0.9 años). Se midieron variables antropométricas de peso y talla. Se calculó el Índice de Masa Corporal (IMC). La coordinación motora (CM) se evaluó utilizando la batería de Körperkoordinationstest Für Kinder (KTK). Los resultados mostraron que en las mujeres el grupo Normopeso tenía un mejor desempeño en la transposición lateral que los grupos Sobrepeso y Obesidad (p˂0.05). En los hombres, el grupo Normopeso superó al grupo Obesidad en los saltos monopedales (p˂0.05). Además, al analizar las diferencias entre sexos, se determinó que las mujeres registraron mayor puntaje que los hombres en el equilibrio a la retaguardia (p<0.05), por su parte, los hombres registraron mejores rendimientos en saltos laterales, transposición lateral y el puntaje total del KTK (p<0.05). Se concluye que existe menor índice de CM en los escolares con elevado IMC, y que existen diferencias significativas entre hombres y mujeres en el equilibrio, saltos laterales, transposición lateral y el puntaje total del test KTK.

The objective of this research was to analyze the relationship between motor coordination (CM) and Body Mass Index in Chilean schoolchildren between 7 and 9 years of age. The study was observational cross-sectional, correlational and descriptive study. 180 students of both sexes were evaluated (90 women aged 8.4 ± 0.9 years and 90 men aged 8.5 ± 0.9 years). Anthropometric weight and height variables were measured and the Body Mass Index (BMI) was calculated. The CM was evaluated using the battery of Körperkoordinationstest Für Kinder (KTK). The results showed that in the lateral transposition, the normal weight group outperforms the overweight and Obesity group (p˂0.05) for women. For men, in monopedal jumps, the normal weight group also outperformed the obesity group (p˂0.05). In addition, when analyzing the differences between the sexes, it was noted that women had a higher score than men in the rear balance (p˂0.05). On the other hand, men had performed better in lateral jumps, lateral transposition and the total KTK score (p˂0.05). In conclusion, the study found that there was a lower CM index in schoolchildren with a high BMI, and that there were significant differences between men and women in terms of balance, lateral jumps, lateral transposition, and the total score of the KTK test.

Conclui-se que há menor índice de CM em alunos com IMC elevado, e que existem diferenças significativas entre homens e mulheres para equilíbrio, saltos laterais, transposição lateral e pontuação total do teste KTK.

Blood flow restriction can improve knee proprioception and motor coordination after anterior cruciate ligament reconstruction / 中华物理医学与康复杂志

Objective:To explore any effect of blood flow restriction during exercise on knee proprioception and motor coordination after anterior cruciate ligament (ACL) reconstruction.Methods:Thirty patients recovering from ACL reconstruction were randomly divided into an experimental group and a control group, each of 15. Both groups were given routine rehabilitation training, while the experimental group was additionally provided with 45 minutes of training with blood flow restriction, 3 times a week for 8 weeks. The blood flow restriction training involved constant pressure in the groin while the patient performed knee flexion and extension resistance training, squats, alternate knee flexion and extension and ergometer cycling. Before and after the intervention, both groups′ knee function, proprioception and lower limb motor coordination were evaluated using the Lysholm knee scale, the Humac isokinetic measurement system and surface electromyography.Results:Before the experiment there were no significant differences between the two groups in any of the measurements. After the intervention, both groups′ average Lysholm score had improved significantly, and errors in reproducing a knee angle had decreased significantly. Significantly better improvement was observed in the observation group than in the control group. That group′s average coordinated contraction rate on the affected side in extension and flexion was also significantly better than the control group′s ave-rage. Indeed, there were no significant differences in the contraction rates between the healthy and affected sides.Conclusions:Training with restricted blood flow can significantly improve knee function, proprioception and motor coordination after anterior cruciate ligament reconstruction.

Physical and motor profile of children between 6 and 10 years old according to levels of cardiorespiratory fitness / Perfil físico e motor de crianças entre os 6 e os 10 anos de idade em função dos níveis de aptidão cardiorrespiratória

Abstract This study aimed to compare the physical profile and motor profile of children from 6 to 10 years old, according to their level of cardiorespiratory fitness (CRF). Participated 2036 children from 6 to 10 years old from São José dos Pinhais - PR. Assessed variables were stature, corporal mass, Body mass index (BMI), physical fitness (PF), and gross motor coordination (GMC). The CRF was assessed by the total distance during the 6 minutes walking test. A battery of tests KTK evaluated the GCM. The children were classified according to their levels of CRF (low-moderate-elevated). Differences between groups were tested using ANOVA one way. Data analysis was made in the SPSS software, with a meaningfulness of 5%. Children with low levels of CRF showed higher values of adiposity. On the PF tests, children with low levels of CRF showed higher values of prehension and worse performance in the other tests. Regarding GMC, children with low levels of CRF had lower coordinative performance. Meaningful differences were found in the comparisons between different groups (low-moderate, low-elevated) with an advantage in the results in moderate levels of CRF. Obtaining average levels of CRF can bring protective benefits in other variables in children's growth process and development during infancy. Evaluating the CRF doesn't only get a momentary evaluation. Still, it can also do the monitoring of an essential variable of health, as well as indicate a predisposition about other physical-motor variables.

Resumo Comparar o perfil físico e motor de crianças dos 6 aos 10 anos, conforme os seus níveis de aptidão cardiorrespiratória (AptC). Participaram do estudo 2036 crianças de seis a 10 anos de idade de São José dos Pinhais-PR. Foram avaliados estatura, massa corporal, índice de massa corporal (IMC), aptidão física (AptF) e coordenação motora (CMG). A AptC foi avaliada pela distância total percorrida no teste de seis minutos. A CMG foi avaliada por meio da bateria de testes KTK. As crianças foram classificadas em função dos níveis de AptC (baixo-moderado-elevado). Diferenças entre grupos foram testadas utilizando da ANOVA one way. As análises dos dados foram realizadas no software SPSS, com nível de significância em 5%. Crianças com menor nível de AptC apresentam maiores valores médios adiposidade. Nos testes de AptF, crianças com níveis baixos de AptC apresentaram maiores valores de preensão e pior desempenho nos demais testes. Relativamente à CMG, crianças com baixos níveis de AptC apresentaram piores desempenho coordenativo. Diferenças significativas foram encontradas para as comparações entre os outros grupos (baixo-moderado; baixo-elevado) com vantagem nos resultados nos níveis moderados a elevados de AptC. Obter níveis moderados de AptC pode trazer benefícios protetores em diferentes variáveis do processo de crescimento e desenvolvimento de crianças durante a segunda infância. Avaliar a AptC não traz somente uma avaliação momentânea, como pode ser feito o monitoramento de uma importante variável de saúde bem como indicar uma predisposição sobre outras variáveis físico-motoras.

Comparative CNS activities of chlorpheniramine maleate, ebastine, and fexofenadine in Swiss albino mice

Background: Not all second-generation antihistamines were devoid of the central nervous system (CNS) effects such as cognitive and psychomotor impairment. Although these drugs penetrate blood–brain barrier (BBB) to lesser extent, many of them have been found to produce dose-related impairment of CNS functions with interdrug differences present among them. Aim and Objective: This study is aimed to analyze and compare the effects of different antihistamines (first and second generation) on the CNS using Swiss albino mice. Materials and Methods: Twenty-four Swiss albino mice of either sex weighing around 25 - 30 g were randomly divided into six groups with six in each group. Antihistamines such as chlorpheniramine maleate (CPM), ebastine, and fexofenadine were administered to respective groups through oral route. Their effects on CNS were evaluated using rotarod and actophotometer. The data were analyzed using statistical methods. Results: CPM produced significant reduction (P < 0.05) in motor coordination and spontaneous locomotor activity. Ebastine does not have any effect on motor coordination but significant reduction (P < 0.05) in spontaneous locomotor activity. Fexofenadine does not have any effect on motor coordination and spontaneous locomotor activity. Conclusion: We conclude that CPM has significant CNS depressant actions, ebastine has minimal CNS depressant actions, and fexofenadine does not have CNS depressant actions.

Parâmetros de dificuldade e discriminação das tarefas motoras do instrumento KTK: uma análise a partir da teoria de resposta ao item / Difficulty and discrimination parameters of the KTK instrument motor tasks: an analysis from item response theory

RESUMO Nas últimas décadas o uso da Teoria de Resposta ao Item (TRI) tem sido implementada devido à complexidade dos cálculos estatísticos que permite analisar com profundidade testes educacionais, questionários e listas de itens aplicados em diferentes áreas como a psicometria, ranking esportivo e pedagogia. A partir dessa premissa este estudo teve como objetivo verificar a adequabilidade das tarefas motoras do KTK analisando o grau de dificuldade e parâmetro de discriminação de cada tarefa motora. Participaram do estudo 385 crianças de 5 a 14 anos. O instrumento avaliado foi o KTK (Körperkoordinationstest für Kinder), composto por quatro tarefas motoras: trave de equilíbrio, saltos monopedais, saltos laterais e transposição de plataformas. As análises foram conduzidas a partir dos dados brutos adquiridos em cada tarefa motora. A fim de verificar a estrutura fatorial da matriz teórica subjacente ao teste, foi realizada uma análise fatorial exploratória seguida da análise fatorial confirmatória. Os parâmetros de dificuldade e discriminação de cada tarefa motora foram analisados a partir do modelo de resposta gradual, fundamentado na teoria de resposta ao item (TRI). Os resultados corroboram com a estrutura fatorial sugerida na versão original do KTK, apresentando apenas um fator, chamado de coordenação motora. Os indicadores da Análise Fatorial Confirmatória (AFC) foram aceitáveis, indicando boa qualidade do modelo ajustado para a amostra. Conclui-se que a análise de TRI evidenciou diferenças nos parâmetros de dificuldade e de discriminação entre as tarefas motoras do KTK, demonstrando a importância de considerar uma ponderação na criação de tabelas normativas de avaliações motoras.

ABSTRACT In the last decades, the use of Item Response Theory (IRT) has been implemented due to the complexity of statistical calculations that allows for in-depth analysis of educational tests, questionnaires and lists of items applied in different areas such as psychometry, sports ranking and pedagogy. Based on this premise, this study aimed to verify the suitability of the KTK motor tasks analyzing the degree of difficulty and discrimination parameters of each motor task. A total of 385 children aged 5 to 14 years participated in the study. The instrument evaluated was the KTK (Körperkoordinationstest für Kinder), consisting of four motor tasks: balance beam, single-pedal jumps, side jumps and platform transposition. Analyzes were conducted from the raw data acquired in each motor task. In order to verify the factor structure of the theoretical matrix underlying the test, an exploratory factor analysis was performed, followed by a confirmatory factor analysis. The difficulty and discrimination parameters of each motor task were analyzed using the gradual response model, based on the Item Response Theory (IRT). The results corroborate the factor structure suggested in the original version of the KTK, presenting only one factor, called motor coordination. The AFC indicators were acceptable, indicating good quality of the model adjusted for the sample. It is concluded that the IRT analysis evidenced differences in the parameters of difficulty and discrimination between the KTK motor tasks, demonstrating the importance of considering a weighting in the creation of normative tables of motor assessments.

TGfU in the teaching of handball at school: impacts on the motor coordination and technique in the game

Abstract Aim: This study investigated the impact of a handball-teaching program through the understanding of the TGfU on motor coordination (MC) and technical skills of students. Methods: The sample consisted of 43 students of both genders, with a mean age of 14.3 years (± 0.46), divided into two groups, G1 - Teaching Games of Understanding (TGfU) and G2 - TGfU + MC, and both received 20 classes. We used the Körperkoordinationstest für Kinder (KTK) for the assessment of MC and the Game Performance Assessment Instrument (GPAI) for technical skills in handball. Results: The categorization confirmed the reliability of the application of teaching programs and the results showed that, after the intervention, both groups presented meaningful improvements in MC, considering time and gender effect. The female students presented a larger impact on MC in both teaching programs, while the male students obtained a larger impact in the technical skill execution index when received the TGfU + MC model. Still, the relative frequency for the classification of a good MC increased in both groups after the intervention, and the normal MC was the one with the highest frequency in both groups and genders after the proposed program. Conclusion: We concluded that the teaching program was able to provide meaningful improvements in MC considering both groups and that the proposal of the inclusion of specific MC elevated the impact of technical skills for male students.

Effects of long-term alcohol consumption on synaptic plasticity of mossy fiber-granule cells in cerebellar cortex and motor coordination function in mice / 中华行为医学与脑科学杂志

Objective:To investigate the long-term alcohol consumption on synaptic plasticity of mossy fiber-granule cells in cerebellar cortex and motor coordination function in mice.Methods:Thirty healthy male ICR mice aged 6-8 weeks were divided into saline group (control group)and alcohol consumption group(alcohol group) according to random number table with 15 in each group. The mice in alcohol group were injected intraperitoneally with 15% ethanol (1.6 g/kg), while the mice in control group were injected with the same volum of normal saline, all mice were injected intraperitoneally once a day for 28 consecutive days. Walking obstacle test and rotating rod fatigue test were used to observe the motor coordination ability and learning ability of mice. Electrophysiological patch clamp technique was used to detect the field potential changes of long-term synaptic plasticity induced by blowing stimulation. SPSS 22.0 software was used for statistical analysis.Independent sample t-test, paired t-test and repeated measurement analysis of variance were used for comparison between the two groups before and after intervention. Results:The electrophysiological results showed that the amplitude percentage of field potential N1 wave in the control group after blowing stimulation was (130.4±3.3)%, which was higher than that before stimulation ((100.6±2.7)%) ( t=27.07, P<0.01). And the percentage of area under N1 standardized waveform after stimulation ((128.8±4.5)%) was greater than that before stimulation ((100.2±3.5)%) ( t=19.43, P<0.01). There was no significant difference in the amplitude percentage of N1 wave in alcohol group ((97.8±4.3)%) after blowing stimulation compared with that before stimulation ((99.5±5.6)%) ( t=0.93, P>0.05). And also there was no significant difference in the area percentage under N1 wave after stimulation ((96.8±3.6)%) compared with that before stimulation ((100.2±4.2)%) ( t=2.38, P>0.05). The results of walking obstacle test showed that the total number of errors (3.14±0.19) in the alcohol group was higher than that in the control group(1.52±0.29) ( t=17.87, P<0.01), and the total error time ((63.85±9.34) ms) was longer than that in the control group ((28.93±7.21) ms) ( t=11.45, P<0.01). The results of repeated measurement analysis of variance showed that there was an interaction between time and group in the falling speed and falling latency of the two groups of mice in the rotating rod fatigue experiment ( F=4.5, 455.1, both P<0.05). The drop speed of mice in the alcohol group was significantly lower than that in the control group from day 1 to 7 (all P<0.05). The fall latency of mice in the alcohol group from day 1 to 7 was shorter than that in the control group, and the difference was statistically significant (all P<0.05). Conclusion:Long-term alcohol consumption impairs synaptic plasticity in the granular layer of mice and leads to a significant decline in motor coordination and motor learning ability.

The Effectiveness of Occupational Therapy Handwriting Intervention for Children with Motor Coordination Issues: A Systematic Review (Keberkesanan Terapi Cara Kerja Bagi Intervensi Tulisan Tangan Terhadap Kanak-kanak Dengan Masalah Koordinasi Motor: Tinjauan Literatur Sistematik) / Jurnal Sains Kesihatan Malaysia

@#Handwriting difficulty is one of the main issues among school children, especially for those with motor coordination issues. The aim of this systematic review is to evaluate the effectiveness of occupational therapy interventions in handwriting components for children with motor coordination issues. Current research articles were systematically searched according to the PRISMA guidelines. Two hundred and sixty-eight (n=268) research articles were identified; however, only ten (n=10) were eligible to be evaluated for this study. Studies were appraised by using McMaster Critical Review Form-Quantitative Studies. Descriptive synthesis was executed due to the heterogeneity of included studies. The review found various types of intervention conducted by occupational therapists to have a positive effect on handwriting performance components among children with motor coordination issues. Types of intervention used were visual, motor, perceptual, sensory, activity of daily living skills, training device and assistive technology and specific handwriting programs. Most handwriting intervention showed effectiveness to improve handwriting performance in motor function, visual and perceptual components. Future research should focus on homogeneity of Occupational Therapy (OT) intervention to improve handwriting performance by using specific handwriting programmes and similar standardised evaluation instruments. Practitioners of OT intervention should consider collaboration with teachers, parents and other health professionals to expedite effectiveness of intervention in handwriting performance components.

Relación entre condición física global, coordinación motriz y calidad de vida percibida en adolescentes españoles / Relationship between overall physical condition, motor coordination and perceived quality of life in Spanish adolescents

Resumen La sociedad actual plantea la necesidad de incorporar a la educación aquellas capacidades relacionadas con el cuerpo y su actividad motriz dentro de los márgenes de la salud, pues estas resultan determinantes para el desarrollo integral de la persona. Teniendo esto en cuenta, el objetivo del presente estudio fue analizar la relación entre la condición física global (CF), la coordinación motriz (CM) y la calidad de vida percibida (cvp) en adolescentes españoles. Para esto, se diseñó un estudio descriptivo transversal con 1037 adolescentes de 14 a 16 años de edad, y se utilizó el Cuestionario de salud SF-36 para evaluar la cvp, y la Batería de condición física relacionada con la salud para evaluar la CF global y la CM. Los resultados muestran que los sujetos con mayor CF tuvieron valores promedio más elevados en las variables de función física (p < .001), rol físico (p < .001), vitalidad (p < .05), función social (p < .001), rol emocional (p < .01), salud mental (p < .001) y calidad de vida total (p < .001); mientras que aquellos con menor CF presentaron puntuaciones superiores en dolor corporal (p < .001). Asimismo, los sujetos que mostraron mayor CM obtuvieron mejores registros en salud general, vitalidad, función social y calidad de vida total (p < .001 en todos los casos), y registros inferiores en función física y rol físico (p < .001 en ambos casos). Los resultados de este estudio sugieren que tener una mayor CF, así como una mayor CM, pueden ser variables predictoras de una mejor cvp en adolescentes españoles.

Abstract Today's society poses the need to incorporate into education those capacities related to the body and its motor activity within the margins of health, since these are determining factors for the integral development of the person. Bearing this in mind, the aim of this study was to analyze the relationship between overall physical condition (PC), motor coordination (MC) and perceived quality of life (PQL) in Spanish adolescents. For this purpose, a cross-sectional descriptive study was designed involving 1037 adolescents aged between 14 to 16 years. The SF-36 Health Questionnaire was used to assess the PQL, and the Health-related Physical Condition Battery, to evaluate global PC and MC. The results show that participants with higher PC had higher average values in the variables physical function (p < .001), physical role (p < .001), vitality (p < .05), social function (p < .001), emotional role (p < .01), mental health (p < .001), and total quality of life (p < .001); while those with lower PC had higher scores in body pain (p < .001). Likewise, participants who showed higher MC obtained better records in general health, vitality, social function, and total quality of life (p < .001 in all cases), and lower records in physical function and physical role (p < .001 in both cases). The results of this study suggest that having a higher PC, as well as a higher MC, maybe predictive variables of a better PQL in Spanish adolescents.

Desempenho motor e índice de massa corporal em crianças de cinco anos / Motor performance and body mass index in children of five years

As crianças estão cada vez mais utilizando brincadeiras e jogos eletrônicos, passando muitas horas diante da televisão e isso pode atrapalhar o processo de desenvolvimento motor bem como o desenvolvimento do processo de sobrepeso e obesidade. A educação física escolar é um importante aliado na promoção de hábitos de vida mais ativos, sendo a educação infantil a primeira etapa de escolarização e prática de atividades motoras desta fase é fundamental. O objetivo desse estudo foi avaliar o índice de massa corporal (IMC) e o desempenho motor de escolares com idade de cinco anos dos Centros Municipais de Educação Infantil em Divinópolis/MG. O desempenho motor foi avaliado com o Teste de Coordenação Corporal para Crianças (Körperkoodinations test Für Kinder ­ KTK) composto por quatro testes: equilibrar-se andando de costas, saltos monopedais, saltos laterais e transposição lateral sobre plataforma. O IMC foi calculado a partir de medidas de peso e altura. Os resultados do presente estudo demonstram que 80,65% da amostra apresenta deficiência na coordenação motora, e quando comparado entre os sexos, os meninos apresentaram melhor coordenação motora que as meninas. Ao analisar o IMC e a coordenação motora não foi encontrada qualquer relação significativa entre eles. Pode-se concluir com o presente estudo que o IMC não influenciou no desempenho motor dos alunos, e que a maioria dos alunos está com a coordenação motora abaixo do esperado. A falta de aulas de educação física com o professor especialista e estímulos específicos para o desenvolvimento motor podem ter contribuído para os resultados encontrados neste estudo, reforçando a necessidade do professor de educação física n o ensino infantil.(AU)

: Children are increasingly using games and electronic games, spending many hours in front of the television and this can hinder the process of motor development as well as the development of overweight and obesity. School physical education is an important ally in the promotion of more active life habits, with early childhood education being the first stage of schooling and the practice of motor activities in this phase is fundamental. The objective of this study was to evaluate the body mass index (BMI) and the motor performance of schoolchildren aged five years old from the Municipal Centers of Early Childhood Education in Divinópolis / MG. Motor performance was assessed with the Body Coordination Test for Children (Körperkoordinations test Für Kinder - KTK) composed of four tests: balance on your back, single-legged jumps, lateral jumps and lateral transposition on a platform. BMI was calculated from weight and height measurements. The results of the present study showed that 80.65% of the sample has impaired motor coordination, and when compared between genders, boys showed better motor coordination than girls. When analyzing BMI and motor coordination, no significant relationship was found between them. It can be concluded with the present study that the BMI did not influence the motor performance of the students, and that the majority of the students have motor coordination below the expected. The lack of physical education classes with the specialist teacher and specific stimuli for motor development may have contributed to the results found in this study, reinforcing the need for physical education teachers in early childhood education.(AU)

Análise da Lateralidade e Destreza Manual em Crianças com Transtorno do Espectro Autista / Analysis of Laterality and Manual Dexterity in Children with Autistic Spectrum Disorder

RESUMO: Este estudo teve como objetivo analisar a lateralidade e a destreza manual em crianças com Transtorno do Espectro Autista (TEA). Do ponto de vista da motricidade humana, a lateralidade contribui para o processo de maturação motora. Figura-se entre as principais características do autismo o atraso nas habilidades motoras grossas e finas, com piora progressiva no quadro. Analisar o nível de lateralidade do indivíduo com TEA torna-se importante por possibilitar uma direção na intervenção motora com o intuito de melhorar a funcionalidade do autista e sua qualidade de vida. A amostra deste estudo foi composta por oito crianças, alunos de uma instituição de ensino pública, do sexo masculino, com idade média de 8,75±1,83 anos e diagnosticadas com TEA com base no DSM-V. Os resultados mostraram que os participantes do estudo parecem apresentar lateralidade destra e, também, melhor desempenho com a mão preferida em uma tarefa de destreza manual. Observou-se que, na tarefa que exigiu maior atenção e destreza, a diferença no desempenho das mãos foi significativa. Já na tarefa com menor demanda atencional e de destreza manual, o desempenho entre as mãos não foi significante, porém foi nesse momento que foram observados os maiores erros na execução. A motivação pode ser uma variável fundamental para o desempenho motor em tarefas que avaliam o tempo de execução. É importante uma maior ênfase no desenvolvimento da motricidade desses indivíduos durante a fase escolar para diminuir as dificuldades motoras e, consequentemente, melhorar a qualidade de vida, sensação de bem-estar, autonomia e interação social.

ABSTRACT: This study aimed to analyze laterality and manual dexterity in children with Autism Spectrum Disorder (ASD). From the point of view of human motor skills, laterality contributes to the motor maturation process. Among the main characteristics of autism is the delay in gross and fine motor skills, with progressive worsening in the condition. Analyzing the level of laterality of the individual with ASD becomes important because it allows a direction in the motor intervention in order to improve the functionality and quality of life of the autistic person. The sample of this study was composed of eight children, students of a public education institution, male, with an average age of 8.75 ± 1.83 years old and diagnosed with ASD based on the DSM-V. The results showed that the study participants seem to have right handedness and also better performance with the preferred hand in a manual dexterity task. It was observed that, in the task that demanded more attention and dexterity, the difference in hand performance was significant. In the task with the lowest attentional demand and manual dexterity, the performance between the hands was not significant; however, it was at that moment that the biggest mistakes in execution were observed. Motivation can be a fundamental variable for motor performance in tasks that assess execution time. It is important to emphasize the development of the motor skills of these individuals during the school phase to reduce motor difficulties and, consequently, improve quality of life, sense of well-being, autonomy and social interaction.

Participaram do estudo 351 estudantes com idades entre 6 a 11 anos, alunos de três escolas, duas da rede privada e uma pública situadas no Distrito Federal. Os pesquisadores realizaram 3 visitas para aplicação dos instrumentos de pesquisa, realizados de forma randomizada, sendo determinadas por sorteios. Os instrumentos de pesquisa foram aplicados dentro das dependências da escola, divididos em três blocos: 1) teste de atenção por cancelamento e teste de trilhas A e B (aplicados de forma coletiva); 2) testes de capacidade aeróbia Intermittent Recovery Test ­ level 1 (Yo-Yo); 3) anamnese, composição corporal e o teste Körperkoordination für Kinder (KTK). A competência motora ≥70,5 e ≥69,45 escores mostrou-se preditora da atenção (área=0,63; IC=0,55-0,70) e função executiva (área=0,86; IC=0,82-0,90), respectivamente e estes indicadores representam 2,52 e 8,41 vezes mais chances de acontecerem em comparação as crianças que obtiveram menor valores de escore motor. A circunferência da cintura apresentou-se como um bom preditor da atenção (área=0,68; IC=0,61-0,76), e função executiva (área=0,61; IC=0,53-0,58), desta forma, as crianças com circunferência da cintura ≤ 63,5 e ≤ 69,5 apresentaram uma proporção de 60 a 28% maior de chances de alcançarem maiores valores de atenção e função executiva respectivamente. O percentual de gordura corporal também demonstrou capacidade de preditiva da atenção (≤27,7% área=0,61; IC=0,53-0,68) e função executiva (≤25,8% área=0,62; IC=0,5 6-0,69). A circunferência da cintura, percentual de gordura corporal e coordenação motora destacaram-se por apresentarem capacidade preditiva sobre o desempenho da atenção e FE. Ademais, a co ordenação motora e circunferência da cintura podem ser utilizadas como indicadores de risco ou performance daatenção e FE em crianças de 6 a 11 anos....(AU)

Effect of Tocotrienol Rich Fraction (TRF) On Muscles Reinnervation After Sciatic Nerve Crush Injury In Rats

@#Introduction: Muscle denervation is a process where muscles lose nerve supply due to neural damage and this may lead to paralysis in human. Muscle denervation is mainly caused by peripheral nerve injuries especially in the lower extremities that resulted in devastating effect on human daily functions and routines. Tocotrienol Rich Fraction (TRF) consist of 75% of tocotrienols have shown potential neuroprotective properties. The objective of this study is to observe motor coordination and histological characteristics on muscles that underwent sciatic nerve crush injury and supplemented with TRF. Methods: A total of 104 Sprague-Dawley rats were divided into four groups; normal group (n=8) with no sciatic nerve crush injury, negative control (n=32) with sciatic nerve crush injury at hindlimb without treatment, positive control (n=32) sciatic nerve crush injury treated with 500 µg/kg/day of methylcobalamin, and experimental group (n=32) of rats that underwent sciatic nerve crush injury and treated with 200 mg/kg/day of TRF. Result: Skeletal muscles which located at hind limb; Soleus Muscle and Extenstor Digitorum Longus Muscle (EDL) muscle have shown an increasing in weight when it is supplemented with TRF 200 mg/kg/day and improved myelin layer of nerve. Conclusion: This study showed that TRF has the potency to improve reinnervation rate and neuron supply in hind muscle.

Changes in dynamic stability, motor coordination and joint mechanics of the lower extremity during stair descent and performing phone task / 中国组织工程研究

BACKGROUND: The coupling and coordination control of the multi-link rigid body of human body is the key to stable walking. It is reported that the use of cell phones greatly increases the chance of falling down stairs when walking; however, it lacks the analysis of the dynamic stability, motion coordination and joint mechanics of the lower limbs when walking down stairs with cell phone intervention. OBJECTIVE: To investigate the effects of cell phone on coupling control strategy of the multi-link rigid body in lower extremity during stair descent. METHODS: Twenty healthy university students were recruited and conducted the stair descent under no-interference (single task) and cell phone (phone task) randomly. Using the method of synchronous acquisition of 3D kinematics and dynamics, the kinetic and kinematic data were synchronously collected to acquire the parameters of stair descent under both conditions. RESULTS AND CONCLUSION: (1) The intervention of phone task significantly reduced the dynamic stability in anterior-posterior/media-lateral direction, the first knee extension moment peak, the first dorsiflexion moment peak, the second hip flexion moment peak in sagittal plane during stance phase, and significantly increased the mean and standard deviation of hip-knee/knee-ankle relative phase angles during swing phase. (2) It is concluded that when the gait of human body changes from time to time, the coupling control ability of multi-link rigid bodies decreased and the risk of falling increased. (3) The intervention of phone task reduces the supporting moment of lower limbs in the supporting phase, reduces the stability of adjacent joint coordination control in the swinging phase, reduces the dynamic stability in front, back and inside directions, and increases the risk of falling.

The relationship of sports practice with motor performance, selective attention, cognitive flexibility and processing speed in children aged 7 to 10 years / A relação da prática esportiva com o desempenho motor, atenção seletiva, flexibilidade cognitiva e velocidade de processamento em crianças de 7 a 10 anos

INTRODUCTION: Sports initiation is usually started during childhood and adolescence, and the beneficial effects of this practice for physical and motor capacities are already known. Recent research has shown the potential of sports to stimulate and modify cognitive development. OBJECTIVE: To verify the relationship of sports practice during childhood on cardiorespiratory, motor, attention, cognitive flexibility and cognitive processing speed. METHODS: 130 students aged 7 to 10 years participated in the study, of which 68 were athletes and 62 non-athletes, divided into sports group and control group. The researchers carried out three visits for the application of the research instruments, which were carried out in a randomized manner within the school premises, divided into three blocks: 1) attention test for cancellation and test of tracks A and B (applied collectively); 2) jumping tests; 3) anamnesis, body composition and the Körperkoordination für Kinder (KTK) test. RESULTS: Children practicing sports obtained lower values in the weight (28 ± 10.08 kg vs 33.9 ± 15.3 kg), waist circumference (57.8 ± 7.7 cm vs 61.7 ± 9.6 cm) and circumference of the hip (69.1 ± 9.5 cm vs 72.8 ± 10.5 cm). In addition, we observed higher values in single-hops scores (96.9 ± 17.3 vs 85.6 ± 14.3) and lateral jumps scores (99.1 ± 18.8 vs 91.2 ± 18.0) compared to children who do not play sports. (p < 0.05). The high performance in single-heel jumps, side jumps, motor quotient, B-trails and B-A trails presented as predictors of sports practice (CI > 0.50_. CONCLUSION: The results indicated a positive relationship between children practicing sports in childhood and interesting benefits in the ability of cognitive flexibility, without expressing differences in motor coordination compared to non-practicing children.

INTRODUÇÃO: A iniciação esportiva é geralmente iniciada durante a infância e adolescência. Já é conhecido os efeitos benéficos desta prática para as capacidades físicas e motoras. Pesquisas recentes vêm demonstrando o potencial da prática esportiva em estimular e modificar o desenvolvimento cognitivo OBJETIVO: Analisar a relação da prática esportiva durante a infância na coordenação motora, atenção, flexibilidade cognitiva e velocidade de processamento cognitivo MÉTODO: Participaram do estudo 130 estudantes com idades entre 7 a 10 anos, sendo 68 praticantes de modalidades esportivas e 62 não praticantes de modalidades esportivas, divididos em grupo de esportistas (GE) e grupo controle (GC). Os pesquisadores realizaram três visitas para aplicação dos instrumentos de pesquisa, os quais foram realizados de forma aleatorizada dentro das dependências da escola, divididos em três blocos: 1) teste de atenção por cancelamento e teste de trilhas A e B (aplicados de forma coletiva); 2) testes de saltos; 3) anamnese, composição corporal e o teste Körperkoordination für Kinder (KTK) RESULTADOS: Crianças que praticam esporte obtiveram menores valores nas variáveis massa corporal (28 ± 10,08 kg vs 33,9 ± 15,3 kg), circunferência da cintura (57,8 ± 7,7 cm vs 61,7 ± 9,6 cm) e circunferência do quadril (69,1 ± 9,5 cm vs 72,8 ± 10,5 cm). Ademais, observam-se maiores valores nos dos saltos monopedais (96,9 ± 17,3 vs 85,6 ± 14,3) e saltos laterais (99,1 ± 18,8 vs 91,2 ± 18,0) em comparação às crianças que não praticam esporte (p < 0,05). O alto desempenho nos saltos monopedais, saltos laterais, quociente motor, trilhas B e Trilhas B-A apresentaram-se como preditores da prática esportiva (IC > 0,50) CONCLUSÃO: Os resultados indicaram relação positiva entre crianças praticantes de modalidades esportivas na infância e benefícios interessantes na capacidade da flexibilidade cognitiva, sem expressar diferenças na coordenação motora em comparação às crianças não praticantes

Influência do uso de jogos do Microsoft Kinect® sobre o desempenho motor e funcional de criança com transtorno do desenvolvimento de coordenação / Influence of the Microsoft Kinect® games on the motor and functional performance of a child with developmental coordination disorder

Resumo: Introdução Boa coordenação motora é essencial para que crianças sejam capazes de desempenhar diversas atividades cotidianas na escola, em casa e em outros ambientes sociais. Algumas crianças, no entanto, apresentam Transtorno do Desenvolvimento da Coordenação (TDC) o que dificulta tais atividades. Abordagens de realidade virtual (RV) vêm sendo utilizadas em diversos contextos da reabilitação, com destaque para o uso de jogos baseados no movimento. Objetivo Investigar a influência do uso de jogos do Microsoft Kinect® sobre o desempenho motor e funcional de uma criança de 8 anos, com TDC, com treinamento individual. Método Antes e após o treino, a coordenação motora, o condicionamento físico, o equilíbrio e o desempenho funcional nas atividades selecionadas foram avaliados com uso do Questionário de Transtorno do Desenvolvimento da Coordenação (DCDQ-Brasil), do Movement Assessment Battery for Children -2ª edição (MABC-2), do Perceived Efficacy and Goal Setting System (PEGS), da Medida Canadense de Desempenho Ocupacional (COPM) e do teste de caminhada de 2 minutos. Resultados A criança obteve ganho clinicamente significativo nos resultados da COPM, aumento na pontuação nos itens relacionados à habilidades motora grossa no DCDQ-Brasil, bem como melhora no condicionamento físico durante a intervenção, que não foram mantidos na fase pós-intervenção, sugerindo que jogos do Microsoft Kinect® devem ser melhor explorados como estratégia terapêutica para crianças com TDC. Conclusão As limitações do estudo de caso são discutidas com vistas a subsidiar estudos futuros.

Abstract: Introduction A good motor coordination is essential to children to be able to perform daily activities at school, at home, and in other social environments. However, some children have Developmental Coordination Disorder (DCD), which makes it difficult to perform these activities. As a new approach, virtual reality is being used in different rehabilitation contexts, with an emphasis on the use of motion-based games. Objective The aim of this case study was to investigate the influence of the use of Microsoft Kinect® games on the motor and functional performance of an eight years old child with DCD, trained individually. Method Pre and post-assessment of motor coordination, physical fitness, balance, and functional performance in selected activities were conducted using the Developmental Coordination Disorder Questionnaire (DCDQ-Brazil), the Movement Assessment Battery for Children, 2nd edition (MABC-2), the Perceived Efficacy and Goal Setting System (PEGS), the Canadian Occupational Performance Measure (COPM), and the 2-minute walk test. Results The child presented clinically significant gains in the COPM, increased scores on items related to gross motor skills in the DCDQ-Brazil, as well as improvement in physical conditioning during the intervention, which was not maintained in the post-intervention phase, suggesting that the use of Microsoft Kinect® games should be further explored as therapeutic strategy for children with DCD. Conclusion The limitations of the case study are discussed as a means to subsidize future studies.

Physical activity and adhd: evidence on developmental trajectories, transient and durable neurocognitive effects, and real-world applications / Actividad física y tdah: evidencia sobre el desarrollo, efectos neurocognitivos a corto y largo plazo y sus aplicaciones / Atividade física e tdah: evidências sobre o desenvolvimento, efeitos neurocognitivos de curto e longo prazo e suas aplicações

Abstract Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by neurodevelopmental delays. Physical activity (PA) may influence many of the same neurocognitive systems affected by ADHD. Therefore, PA may be a potential tool in treatment and management plans. This review synthesizes findings from studies investigating PA, fitness, and motor coordination. Studies of PA in youth on the spectrum for ADHD were considered in this paper. Main results include: a) cross-sectional studies: children with ADHD evidence PA levels higher than children that seem to be healthy. Childhood coincides with opportunities to free play; however, this advantage dissipates by adolescence, as PA programs become increasingly structured and less inclusive. In adulthood, individuals with ADHD are more likely to be obese and less likely to meet healthy lifestyle guidelines; b) longitudinal studies: PA at earlier stages predicts symptom severity in subsequent stages; and c) further studies: moderate PA activity of limited duration offers neurocognitive benefits. Multi-week intervention studies have tested diverse formats with results that differ based upon the chosen outcome and comparison group utilized. PA interventions that challenge cognition and fundamental movement skills in childhood provide benefits to children with ADHD. They also encourage children and adolescents to participate in structured programs, meet PA guidelines, and include short-term AF as part of daily routines.

Resumen El trastorno por déficit de atención e hiperactividad (TDAH) está caracterizado por retrasos en el desarrollo neurobiológico. La actividad física (AF) puede influir en varios de los mecanismos neurocognitivos que también son afectados por el TDAH; por lo tanto, puede considerarse parte de su tratamiento y manejo. Esta revisión sobre el trastorno resumirá estudios que evaluaron AF, aptitud física y coordinación motora. Fueron incluidos artículos sobre AF en la niñez en el espectro de TDAH. Entre los resultados se encuentran a) estudios transversales: los niños con TDAH presentan niveles de AF más altos que aquellos niños aparentemente saludables. La niñez coincide con oportunidades para participar en juego libre, pero esta ventaja es reducida durante la adolescencia, en la cual la AF es estructurada y menos inclusiva. Durante la adultez, las personas con TDAH están más propensas a ser obesas y a no adoptar las recomendaciones de estilos de vida saludables; b) estudios longitudinales: AF durante etapas tempranas predice la severidad de los síntomas del TDAH en etapas subsecuentes y c) otros estudios: la AF moderada de corta duración brinda beneficios neurocognitivos. Los resultados sobre intervenciones de varias semanas difieren según la variable de interés y el grupo con el cual es comparada la intervención. Las intervenciones de AF que retan las habilidades cognitivas y destrezas de movimientos brindan beneficios a los niños con TDAH. Además, estimulan a niños, niñas y adolescentes a participar en AF estructurada, a cumplir con la recomendación de AF y a incluir AF de corta duración como parte de las rutinas diarias.

Resumo O transtorno do déficit de atenção com hiperatividade (TDAH) caracteriza-se por retardo no desenvolvimento neurobiológico. A atividade física (AF) pode influenciar em vários dos mecanismos neurocognitivos que também são afetados pelo TDAH, portanto, pode ser considerada como parte de seu tratamento e manejo. Esta revisão sobre o transtorno resumirá os estudos que avaliaram a AF, a aptidão física e a coordenação motora. Artigos sobre AF infantil foram incluídos no espectro de TDAH. Entre os resultados estão a) estudos transversais: crianças com TDAH têm níveis mais altos de AF do que aquelas aparentemente saudáveis. A infância coincide com as oportunidades de participar de jogos livres, mas essa vantagem é reduzida durante a adolescência, na qual a AF é estruturada e menos inclusiva. Durante a idade adulta, as pessoas com TDAH são mais propensas a serem obesas e a não adotar as recomendações para terem estilos de vida saudáveis; b) Estudos longitudinais: A fase inicial de AF prediz a gravidade dos sintomas de TDAH nos estágios subsequentes e c) Outros estudos: A AF moderada de curta duração proporciona benefícios neurocognitivos. Os resultados em intervenções de várias semanas diferem segundo a variável de interesse e o grupo com o qual a intervenção é comparada. As intervenções de AF que desafiam habilidades cognitivas e habilidades de movimento proporcionam benefícios às crianças com TDAH. Além disso, estimulam crianças e adolescentes a participarem de AF estruturada, a cumprir a recomendação de AF e a incluir AF de curta duração como parte das rotinas diárias.

Relação entre a coordenação motora e a aptidão física em crianças dos 9 aos 14 anos / Relationship between the motor coordination and physical fitness in children of 9 to 14 years

O presente estudo teve como objetivo analisar o nível de coordenação motora (CM) e de aptidão física (ApF), assim como a relação entre estas variáveis, em crianças do 9 aos 14 anos de idade. Participaram deste estudo quasi-experimental 738 crianças (400 meninos), provenientes dos 21 estabelecimentos de ensino fundamental da rede pública de uma cidade do norte de Portugal. A CM foi avaliada com recurso ao KTK, constituído pelos testes equilíbrio à retaguarda, saltos laterais, saltos monopedais e transferências laterais, enquanto para a ApF foi aplicada a bateria do FITNESSGRAM, constituída pelos testes de corrida vai-vêm, força abdominal, flexão do tronco, flexões de braços e extensão do tronco . Observamos uma associação positiva entre estas variáveis (B=2,697, 95%IC: 2,367- 3,026, p< 0,001), tendo as crianças com melhor coordenação motora apresentado um nível de aptidão física também elevado, o que reforça a importância do envolvimento das crianças em atividades planejadas e apropriadas ao desenvolvimento de habilidades motoras que constituem as bases para um nível saudável de aptidão física...(AU)

The present study aims to analyze the level of motor coordination (MC) and physical fitness (PF), as well as the relationship between these two variables in children from 9 to 14 years old. A total of 738 children (400 boys) participated in this quasi-experimental study, recruited from 21 elementary public schools in a city in the north of Portugal. The MC was evaluated using the KTK, consisting of walking backwards, moving sideways, two-legged jumping and hopping over obstacles, while for the PhF the FITNESSGRAM, consisting of the tests shuttle run (20m), curl-up, sit-and-reach, push-up and trunk lift. We observed a positive association between these variables, and the children with better motor coordination presented a high level of physical fitness, which reinforces the importance of appropriated and planned activities either in school and in the community that form the basis for a level Healthy physical fitness...(AU)

Correlação entre índice de massa corporal (IMC) e velocidade em saltos alternados em crianças / Correlation between body mass index (BMI) and speed in alternated jumps in children

A obesidade infantil vem em uma crescente pelo mundo inteiro e acredita-se que pode ser desecandeada pelo efeito negativo que os baixos níveis da coordenação motora podem causar sobre os níveis de atividade física e aptidão física durante a infância. Estudos analisaram a relação entre coordenação motora e composição corporal, e apontaram uma carência nas investigações sobre a influência do peso corporal em tarefas motoras específicas. Mediante ao exposto, o objetivo do presente estudo foi analisar a relação entre o Índice de Massa Corporal (IMC) e a velocidade em saltos alternados em crianças. Participaram do estudo 98 escolares com idade entre 6 e 10 anos. Para avaliação da velocidade de saltos alternados utilizou-se de uma das provas do teste Teste de Coordenação Corporal para Crianças (Köperkoordination Test für Kinder - KTK) que avalia saltos laterais por meio de teste específico. A análise estatística foi realizada por meio do programa R- Plus, o qual foi aplicado o teste de Mann-Whitney para verificar as diferenças do quociente motor (QM) entre meninos e meninas, Spearman para correlação entre o QM e IMC; e ANOVA para as diferenças entre a classificação do peso e o QM, sendo adotado nível de significância de 5% (p <0,05). Os resultados demonstraram não haver diferença estatística significativa entre os sexos para as variáveis analisadas. Entretanto, os meninos atingiram valores maiores para idade, IMC e QM. Na correlação entre o IMC e QM dos saltos laterais das crianças avaliadas, houve correlação negativa fraca, demonstrando que o IMC não teve grande influência no desempenho motor dos saltos quando analisado ambos os gêneros juntos. Tais resultados demonstram não haver correlação do IMC e a habilidade de saltos laterais em crianças com IMC elevado quando analisados de maneira geral. Porém, quando analisado por gênero, os meninos demonstram uma relação inversamente proporcional de IMC e saltos laterais o que não observou-se nas meninas.

Child obesity has been rising worldwide and is believed to be triggered by the negative effect that low levels of motor coordination can cause on the levels of physical activity and physical fitness during childhood. Studies analyzed the relationship between motor coordination and body composition, and pointed to a lack of research on the influence of body weight on specific motor tasks. The purpose of this study was to analyze the relationship between Body Mass Index (BMI) and the speed in alternate jumps in children. A total of 98 students aged 6 to 10 years took part in the study. In order to evaluate the speed in alternate jumps, one of the Köperkoordination Test für Kinder (KTK) tests that evaluates side jumps by means of a specific test was used. Statistical analysis was performed using the R-Plus program, which applied the Mann-Whitney test to verify the motor quotient (QM) differences between boys and girls, the Spearman test for correlation between QM and BMI; and ANOVA for the differences between weight classification and QM; as well as adopting a 5% (p <0.05) significance level. The results showed that there were no significant statistical differences between the sexes for the analyzed variables; however, boys scored higher values for age, BMI and QM. A weak negative correlation was observed between BMI and QM for the lateral jumps of the assessed children, demonstrating that the BMI did not have a great influence on the motor performance of the jumps when both genders were analyzed together. These results show that there is no correlation between BMI and lateral jumping skills in children with high BMI when analyzed in general, but when analyzed by gender, boys demonstrate an inversely proportional relation of BMI and lateral jumps, which was not observed in girls.
