ABSTRACT

ObjectiveTo investigate the effect of transcranial direct current stimulation (tDCS) combined with constraint-induced weight training (CIWT) on Pusher syndrome after stroke. MethodsA total of 60 stroke inpatients with Pusher syndrome in the First Affiliated Hospital of Soochow University from January to December, 2021 were randomly divided into tDCS group, CIWT group and combination group, with 20 cases in each group. The three groups accepted routine rehabilitation training, the tDCS group received anode tDCS, the CIWT group received CIWT of the affected lower limb, and the combination group received CIWT of the affected lower limb and tDCS, for eight weeks. They were assessed with Berg Balance Scale (BBS), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), Burke Lateropulsion Scale (BLS) and Holden Walking Functional Ambulation Category (FAC) before and after treatment. ResultsAfter treatment, the scores of BBS, FMA-LE, BLS and FAC improved (|t| > 1.452, P < 0.05) in all the groups, and improved the most in the combination group (|F| > 1.827, P < 0.05). ConclusiontDCS combined with CIWT of the affected lower extremity can effectively improve the function of stroke patients with Pusher syndrome.

ABSTRACT

Este estudo teve como objetivo investigar, em uma academia da região do Barreiro, zona periférica de Belo Horizonte, se a musculação pode ser considerada como uma atividade de lazer para os seus praticantes. Como estratégia foi realizado um estudo de caso, com abordagem qualitativa e quantitativa. Para coleta de dados, utilizamos de um questionário padronizado e observação participante. Participaram da pesquisa, ao todo, 145 voluntários. Constatou-se que a maioria dos participantes da pesquisa consideram a prática de musculação como uma atividade de lazer, possibilitando espaços de sociabilidade e confraternizações. Não obstante, observamos que, para esses praticantes, o principal motivo para o ingresso e permanência na atividade é a estética corporal (hipertrofia muscular), podendo a musculação ser considerada um estilo de vida prazeroso que possui uma relevância fundamental para os sujeitos pesquisados.


This study aimed to investigate, in a gym of Barreiro's region, peripheral zone of Belo Horizonte, if the weight-training can be considered as a leisure activity to your practitioners. As strategy a study case was conducted, with a qualitative and quantitative approach. In order to collect data, we used a standardized questionnaire and participant observation. 145 volunteers participated in the research. It was found that most research participants consider the practice of weight-training as a leisure activity, which enables spaces for sociability and confraternization. Nevertheless, we observed that, for these practitioners, the main reason for entering and remaining in the activity is body aesthetics (muscular hypertrophy), and weight-training can be considered a pleasant lifestyle that has a fundamental relevance for the researched subjects.

ABSTRACT

ABSTRACT Preparation in bodybuilding involves high-intensity workouts and drastic feeding strategies. Little is known about health risks. Athletes (n=510, 59.8% male) were evaluated about health aspects, anthropometry, and blood pressure (BP). Chronic diseases were reported by 6,6%, but 88.9% of them did not treat; 1.9% reported hypertension, with 15.7% having high BP; and 52.5% reported the use of prohibited drugs in the last 6 months. Body mass index was 26.2±2.5 for man and 22.3±2.2 Kg/m2 for woman. Men had lower monitoring than women by physical education professionals, nutritionists, and physicians (p<0.01). Athletes are exposed to health risks factors such as lack of knowledge about diseases, high use of prohibited substances and less monitoring by professionals among men.

ABSTRACT

@#Exercise selection is one of crucial factors in designing a comprehensive training programme. The exposure of different exercise selection may stimulate the specific adaptation imposed demand. In the construction of any resistance training (RT) programme, it is important to choose whether to apply bilateral (BI) or unilateral (UNI) exercise. The present study aimed to look into the physiological responses of blood glucose (BG) between UNI and BI RT. Quantitative research method was used, RT (UNI versus BI training) as the independent variables whereas BG set as the dependent variable. In order to measure training effects following a single bout of different training intervention (UNI versus BI), a crossover experimental pre and post test design was implemented. A total of sixteen (n = 16) trained women with mean age of 23 (SD = 1.35) years old went through a single bout of RT involved a total body exercise using major muscles group with 80% of 1RM for each protocols (UNI and BI) for 10 repetitions to maximal effort (for 3 sets). Crossover design would be more accurate in exposing different training protocol to a similar characteristic of individuals as compared using different individuals. The results revealed that blood glucose (BG) were statistically changed (p < .001) across times (between PRE to IP, between PRE and 15P as well as between PRE and 30P), and finding shows there is no difference between training protocols (p = .39). Thus, similar responses of UNI and BI RT on BG concentration provides wide selection of exercise method to practitioners specifically to trained women. Future research on UNI versus BI RT could venture onto other types of hormones analysis including insulin, growth hormone and cortisol can be included. Besides, future research should consider a long run study that involve chronic adaptation of RT on human body in order to prevent and alleviate disease.

ABSTRACT

Aim: To compare the effects of different physical activities on laterality and asymmetry values through the side bridge test. Methods: the assessments were carried out in 45 subjects between 18 and 30 years old, 15 Crossfit-trained individuals, 15 weight trained and 15 sedentary. The subjects performed the side bridge test on both sides. After checking the normality and homogeneity of the data, we selected the appropriate statistical analysis for the comparison of the variables, adopting a significance level of α <0.05. Results: there was no statistical difference in the balance ratio; however, significant difference was found in the side bridge test endurance time, in which the Crossfit group obtained longer times on both sides than the other two groups. The side bridge test is a test of simple execution and that in this study the Crossfit group presented better results in the endurance time in the side bridge test. Conclusion: the results of the ratio asymmetry and endurance time are not sufficient to evaluate the resistance of the core muscles but could be an evaluation tool, the side bridge test can be introduced in postural training programs.(AU)

ABSTRACT

Resumen Alfaro-Jiménez, D.; Salicetti-Fonseca, A. y Jiménez-Díaz, J. (2018). Efecto del entrenamiento pliométrico en la fuerza explosiva de deportes colectivos: Un metaanálisis. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 16(1), 1-35. El entrenamiento pliométrico (EPLI) es una herramienta utilizada para mejorar las acciones explosivas en muchos deportes; no obstante, este tipo de entrenamiento no genera el mismo efecto en todos los deportes. El objetivo del estudio fue evaluar el efecto del entrenamiento pliométrico sobre la fuerza explosiva (FE) en los deportes colectivos. En el análisis final, se incluyeron 31 estudios que generaron 50 Tamaños de Efecto (TE). Bajo un modelo de efectos aleatorios, se encontró que el EPLI es efectivo para mejorar la FE (TE=0.98; p=0.00; CI95%=0.77 a 1.20; n=50; Q=174.51; I²=71.95) en deportes de conjunto. Los resultados orientan que para mejorar la FE en este tipo de deportes se debe utilizar el entrenamiento pliométrico sin combinarlo con otro tipo de ejercicios durante al menos diez semanas. Además, este tipo de entrenamiento produce mejorías en la altura de salto, tanto en el periodo preparatorio como en el competitivo, independientemente del tipo de protocolo que se utilice. Se propone realizar estudios confirmatorios con los resultados de este metaanálisis en los que se incluyan otros deportes y se estudie más el tema en mujeres, así como la combinación del EPLI con otro tipo de ejercicios o entrenamientos.


Abstract Alfaro-Jiménez, D.; Salicetti-Fonseca, A. & Jiménez-Díaz, J. (2018). Effect of plyometric training on explosive strength in team sports: A meta-analysis. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 16(1), 1-35. Plyometric training (EPLI) is used to improve explosive actions in many sports; however, this training does not generate the same effect in all sports. The purpose of the study was to evaluate the effect of plyometric training on explosive strength (FE) in team sports. In the final analysis, 31 studies were included generating 50 Effect Sizes (ES). Under a random effects model, the EPLI was found to be effective in improving FE (ES=0.98, p=0.00, CI95%=0.77 to 1.20, n=50, Q=174.51, I²=71.95) in team sports. Results indicate that, in order to improve FE in this type of sports, plyometric training should be used without combining it with other types of exercises for at least ten weeks. In addition, this training improves jump height in both the preparatory as well as the competitive periods, regardless of the type of protocol used. The results of this meta-analysis should be used in confirmatory studies including other sports. In addition, this topic should be further studied in women, as well as the combination between EPLI with other types of excercises and trainings.

ABSTRACT

Energy expenditure in strength training has been the subject of several studies over the last decades. However, the evaluated protocols present important and significant differences, mak-ing it impossible to compare them and reach definitive conclusions. The use of work units (sets x repetitions x load), adding the exercise execution and recovery phase, seems to allow for a better for the understanding of energy expenditure in strength training, being that energy expenditure increases with increasing work level. This, together with the use of observed ab-solute values (kcal or liters of O2) instead of relative values (kcal/min), may allow for a better understanding of the influence on different variables.


El gasto energético en el entrenamiento de resistencia ha sido objeto de varios estudios en las últimas décadas. Sin embargo, los protocolos evaluados presentan diferencias importantes y significativas, por lo que es imposible compararlos y llegar a conclusiones definitivas. El uso de unidades de trabajo (conjuntos x repeticiones x carga), sumando la ejecución del ejercicio y la fase de recuperación, parece permitir una mejor comprensión del gasto energético en el entrenamiento de resistencia, siendo que el gasto energético aumenta con el nivel de trabajo.Ello, junto con el uso de valores absolutos observados (kcal o litros de O2) en lugar de valores relativos (kcal/ min), puede permitir una mejor comprensión de la influencia en diferentes variables.

ABSTRACT

Abstract Although the tri-set system is widely adopted by athletes and experienced weight training practitioners aimed at optimizing the metabolic overload, there are still few works in literature on the effect of exercise order manipulation on this training system. Therefore, this work was aimed at investigating the effect of exercise order manipulation on the number of repeats and training volume using the tri-set system for lower limbs. This is a randomized cross-over design study. The experimental group consisted of 14 healthy men (23.53 ± 5.40 years; 24.51 ± 2.96 kg/m2). Subjects were submitted to two experimental sessions at different exercise order for lower limbs: Sequence A: squat on guided bar, leg press 45° and bilateral leg extension; sequence B: bilateral leg extension, leg press 45° and squat on guided bar. Three sets to volitional fatigue in all exercises were performed, with intensity of 75% 1RM. Superiority for sequence B in the total number of repeats (70.14 ± 13 vs 60.93 ± 7.94 repeats, p = 0.004) and total training volume (9129.64 ± 2830.05 vs 8238.29 ± 2354.20 kg, p = 0.014) was observed. Based on the above, the performance of single-joint exercises before multi-joint exercises in the tri-set system adopted for lower limbs induced higher number of repeats and total training volume.


Resumo Embora o sistema tri-set seja amplamente adotado por atletas e praticantes experientes de treinamento com pesos que buscam otimizar a sobrecarga metabólica, a literatura carece de investigações acerca do efeito da manipulação da ordem dos exercícios nesse sistema de treinamento. Sendo assim, objetivou-se investigar o efeito da manipulação da ordem dos exercícios sobre o número de repetições e volume de treino, utilizando o sistema tri-set para membros inferiores. Trata-se de uma pesquisa com delineamento cross-over aleatorizado. O grupo experimental foi composto por 14 homens saudáveis (23,53 ± 5,40 anos; 24,51 ± 2,96 kg/m2). Os avaliados foram submetidos a duas sessões experimentais em diferentes ordens de exercícios para membros inferiores: sequência A: agachamento na barra guiada, leg press 45° e cadeira extensora bilateral; sequência B: cadeira extensora bilateral, leg press 45° e agachamento na barra guiada. Foram executadas três séries até a fadiga voluntária em todos os exercícios, com intensidade de 75% de 1RM. Observou-se superioridade para a sequência B no número total de repetições (70,14 ± 13,00 vs 60,93 ± 7,94 repetições; p = 0,004) e volume total (9129,64 ± 2830,05 vs 8239,29 ± 2354,20 kg; p = 0,014). Diante do exposto, a execução de um exercício monoarticular antes de multiarticulares, no sistema tri-set adotado para membros inferiores, induziu a um maior número de repetições e volume total de treinamento.

ABSTRACT

The aim of this study was to determine if rating of perceived exertion (RPE) could be used to monitor the internal load during compounded circuit training (CCT) sessions in women. Thirteen young adults women performed three sessions of CCT varying the intensity according to participants' maximum heart rate (50, 70 and 90%HRmax). Throughout the main part of CCT (35min), HR and RPE were measured. Both variables were significantly different among the exercise intensities. However, HR and RPE were not correlated. Probably because HR at the end of exercise was similar to the beginning at 90% and 70% of HRmaxintensities, and lower than the beginning instant at 50% of HRmaxintensity, whereas RPE increased from the beginning instant to the end of exercise for all intensities. Therefore, RPE is suitable to monitor the internal load during CCT sessions in women due to its possibility to detect the (in)tolerance to exercise, despite of the lack of correlation with HR.

ABSTRACT

The purpose of this study was to identify the ground reaction force and lower extremity joint kinetics during clean exercises performed with light and heavy loads. Thirteen male track and field athletes performed the clean exercises from 20 kg to one repetition maximum (1RM). Kinetic data were collected from recorded data using a Vicon motion system (250 Hz) and force platforms (1,000 Hz). The results of the analyses were as follows: (1) Ground reaction force and joint kinetics of hip and ankle were increased by increasing loads in clean exercises. (2) From light to heavy loads, we found relationships between ground reaction force and joint torque of hip in clean exercises. (3) In progressing from light to heavy loads, some subjects continued to involve the muscle group controlling the hip joint as the main power source, while others did not. The results indicate that clean exercises yield different individual characteristics for training. These results suggest that the clean exercise is effective for selectively the hip extensor in all loads.

ABSTRACT

The aim of this study was to analyze the effect of the manipulation of two different exercise orders using the tri-set system on the motor performance in exercises for the chest. Ten male (25.6 ± 5.7 years, 77.0 ± 5.8 kg, 172.9 ± 5.0 cm, 25.7 ± 1.4 kg/m²) with experience in resistance training underwent two experimental sessions, in which the subjects performed two sequences of exercises for the chest: SEQA (bench press, incline bench press, and peck deck) and SEQB (peck deck, incline bench press, and bench press). The load used allowed 8 to 12 repetitions (80% of 1RM) in each exercise. A higher number of repetitions (29 ± 2 reps vs. 26 ± 3 reps, P < 0.001) and a greater total overload (resistance used x repetitions performed = 1,942 ± 172 kg vs. 1,728 ± 234 kg, P < 0.001) were observed in SEQB. The results suggest that in the tri-set system the higher number of repetitions and a greater training volume occur when the single-joint exercise is included before multiple-joint exercises.


O objetivo do presente estudo foi analisar o efeito da manipulação de duas diferentes ordens de exercícios com pesos, utilizando o sistema tri-set sobre o desempenho motor em exercícios para o peitoral. Dez homens (25,6 ± 5,7 anos; 77,0 ± 5,8 kg; 172,9 ± 5,0 cm; 25,7 ± 1,4 kg/m²) com experiência em treinamento com pesos foram submetidos a duas sessões experimentais, nas quais os sujeitos realizaram duas sequências de exercícios para o peitoral: SEQA (supino horizontal, supino inclinado e voador) e SEQB (voador, supino Inclinado e supino horizontal). A carga utilizada permitiu a realização de 8 a 12 repetições (80% de 1-RM) em cada exercício. Verificou-se um maior número de repetições na SEQB (29 ± 2 reps vs. 26 ± 3 reps; P < 0,001) e maior sobrecarga total (carga utilizada x repetições executadas = 1.942 ± 172 kg vs. 1.728 ± 234 kg; P < 0,001). Os resultados sugerem que, no sistema de tri-set, o maior número de repetições e o maior volume de treinamento é alcançado quando o exercício monoarticular é inserido antes dos exercícios multiarticulares.

ABSTRACT

A proporção de idosos na população é cada vez maior nos diferentes países, tornado fundamental o seu estudo em diferentes perspectivas. Desta forma, o objetivo da presente revisão é compreender como o envelhecimento atua no sistema neuromuscular, em especial na força muscular, e como este declínio atua nos aspectos funcionais, ou seja, nas tarefas do dia a dia. Além disso, será abordado como o treinamento de força, em específico visando à melhora da potência muscular, pode ser uma estratégia segura e efetiva no combate aos efeitos adversos do envelhecimento no sistema neuromuscular.

ABSTRACT

Pesquisas mostram resultados divergentes no aumento da força utilizando diferentes amplitudes de movimento (ADM). O objetivo deste estudo foi comparar o número máximo de repetições (NMR) no exercício supino com duas ADM. Quatorze voluntários realizaram a familiarização e o teste de uma repetição máxima (1 RM) nas sessões 1 e 2. Nas sessões 3 e 4 realizaram o NMR em quatro séries a 50% de 1 RM, com um minuto de pausa, com ADM parcial (ADMP) e completa (ADMC). Na ADMP utilizou-se metade do deslocamento vertical da barra comparada a condição ADMC. Foi realizada ANOVA "two-way" com medidas repetidas, seguida pelo "Post hoc" Scheffé. Houve diminuição significante do NMR entre as séries, exceto da terceira para a quarta em ambas ADM. Um maior NMR foi verificado para ADMP. A redução da ADM permite a realização de um maior número de repetições para uma mesma intensidade relativa.


There are divergent results about increases in strength using different ranges of motion (ROM). The aim of this study was to compare the maximum number of repetitions (MNR) in bench press with two different ROM. Fourteen subjects performed familiarization and one repetition maximum (1 RM) tests in sessions 1 and 2. MNR in four sets at 50% of 1 RM, one-minute rest with partial (ROMP) and complete ROM (ROMC) were performed in the third and fourth sessions. The ROMP used half of the bar vertical displacement compared to ROMC. Two-way ANOVA with repeated measures was used to compare the experimental conditions, followed by post hoc Scheffe. There was a significant decrease of the MNR among sets, except from third to fourth sets in both ROM. MNR in all sets was higher in ROMP than ROMC. The reduction of ROM allow to perform higher number of repetitions.


Investigaciones cientificas muestran resultados divergentes en el aumento de la fuerza utilizando diferentes amplitudes de movimiento (ADM). El objetivo de este estudio fue comparar el número máximo de repeticiones (NMR) en un ejercicio de supino con dos ADM. Catorce voluntarios realizaron la familiarización y el test de una repetición máxima (1 RM) en las sesiones 1 y 2. En las sesiones 3 y 4 realizaron o NMR en cuatro series a 50% de 1 RM, un minuto de pausa con ADM parcial (ADMP) y completa (ADMC). ADMP utilizó la mitad del desplazamiento vertical de la barra realizado durante la ADMC. Fue aplicada ANOVA "two-way" con medidas repetidas, seguido del "Post hoc" Scheffé. Se encontró disminución significante del NMR a lo largo de las series, excepto de la tercera para la cuarta en ambas ADM, con el mismo patrón de reducción en ambas ADM. El NMR de la ADMP fue mayor que la ADMC. La reducción de ADM interfirió en el volumen de entrenamiento con mayor número de repeticiones realizadas para una misma intensidad relativa.

ABSTRACT

O principal argumento teórico para a inclusão da atividade física nos programas de promoção da saúde e da qualidade de vida é o paradigma contemporâneo do "estilo de vida ativo". Vários estudos têm mostrado os benefícios do treinamento de força para uma melhor mobilidade e realização das atividades diárias (alimentar-se, vestir-se, banhar-se, locomover-se, etc.) de maneira independente. O objetivo do trabalho foi comparar a percepção de qualidade de vida de professores e alunos de musculação. Participaram do estudo 33 professores e 44 alunos, de ambos os sexos. Foram utilizados um questionário de dados demográficos e o WHOQOL-bref. De modo geral, a maior parte do grupo avaliou sua qualidade de vida como boa ou muito boa (90,9%). Os escores do grupo Professor foram superiores aos valores do grupo Aluno para os domínios Físico e Psicológico. Não houve diferença entre os grupos para o Domínio Social e para a Qualidade de Vida Global. O grupo Aluno teve escore superior para o Domínio Ambiental. Ambos os grupos apresentaram um alto grau de satisfação com os resultados da prática da musculação. A hipótese de que condições de vida e de trabalho, bem como o papel exercido por professores e alunos na academia seriam capazes de influenciar a percepção de qualidade de vida diferenciando estes grupos foi parcialmente confirmada, porém a hipótese de que os alunos teriam maiores escores de qualidade de vida não foi confirmada.


The main theoretical argument for the inclusion of physical activity programs to promote health and quality of life is the contemporary paradigm of the "active lifestyle". Several studies have shown the benefits of strength training for better mobility and daily activities (eating, dressing, bathing, moving around, etc.) independently. The objective was to compare the perceived quality of life for teachers and students of weight training. The study included 33 teachers and 44 students of both sexes. We used a demographic questionnaire and the WHOQOL-bref. In general, the most of the group rated their quality of life as good or very good (90.9%). The scores from the Teacher group were higher than the Student group for the physical and psychological domains. There was no difference between groups for the Social Domain and the Global Quality of Life. The Student group had higher scores for the Environmental Domain. Both groups showed a high degree of satisfaction with the results of practicing weight training. The hypothesis that living and working as well as the role played by teachers and students at the academy would be able to influence the perception of quality of life differentiating these groups was partially confirmed, but the hypothesis that students would have higher scores quality of life has not been confirmed.

ABSTRACT

Os benefícios da prática regular do exercício físico estão claramente estabelecidos na literatura. Entretanto, a escolha do tipo de exercício ideal pode ser mais salutar para indivíduos com doenças específicas e patologias associadas. O propósito desta revisão foi verificar se o treinamento resistido (TR) exerce alguma alteração no colesterol da lipoproteína de baixa densidade (LDL-C). Foram observadas grandes diferenças na literatura, dificultando uma conclusão em relação aos benefícios do TR nesta revisão. No entanto, foi visto que o TR pode ser promissor na redução dos níveis de LDL-C, principalmente em homens e mulheres adultos, em pacientes com diabetes mellitus tipo 1 e tipo 2 e em mulheres pré-menopausa, não mostrando diferenças na população idosa. Os autores concluem que o TR é uma boa opção de exercício físico para indivíduos, principalmente quando o treinamento aeróbio (TA) é contraindicado.


The benefits of exercise regular practice are clearly established in the literature. However, the choice of the ideal exercise may be more beneficial for individuals with specific diseases and associated pathologies. The aim of this review was to determine whether resistance training (RT) promotes any change on low density lipoprotein cholesterol. Important differences were observed in research protocols, making it difficult to define the benefits of RT in this review. However, it was noticed that RT may be promising in reducing LDL-C levels mainly in adult men and women, in patients with diabetes mellitus type 1 and type 2 and in pre-menopausal women, not presenting differences in the elderly population. It was concluded that the RT is an option good of physical exercise for individuals, especially when the aerobic training (AT) is contra-indicated.

ABSTRACT

O envelhecimento é caracterizado por mudanças biológicas, psicológicas e sociais que acabam interferindo no comportamento de indivíduos idosos. À medida que a idade cronológica aumenta, as pessoas se tornam menos ativas e escolhe atividades com menores demandas energéticas, o que provoca diminuição na aptidão física e na capacidade funcional. O objetivo do presente estudo foi verificar o comportamento dos componentes da capacidade funcional após 12 semanas de treinamento com pesos (TP) em mulheres idosas. Para tanto, a amostra foi composta por 60 mulheres com idade média de 65,66 (±4,73) anos, estatura média de 156,42 (±6,13) cm e peso médio de 61,76 (±9,14) quilos. A amostra foi dividida em dois grupos: Grupo GT, composto por 30 mulheres que realizaram treinamento com pesos; e Grupo GA, composto por 30 mulheres que realizaram apenas sessões de alongamento. A capacidade funcional foi analisada através dos testes de 30 segundos de sentar e levantar da cadeira, flexão e extensão de cotovelos, caminhar 10 metros, e levantar e caminhar. Para a análise dos dados foi utilizado teste t de Student (p ≤ 0,05). Os resultados apontaram melhoras significativas em todos os testes para o GT (p < 0,05) e no teste de flexão e extensão de cotovelo para o GA (p = 0,00). Conclui-se que um programa de TP estruturado visando o trabalho dos principais grupos musculares pode ser utilizado para a manutenção da população idosa fisicamente independente.


The aging process can be characterized by biological, psychological and social changes that affect the aging people´s behavior. As the chronological age increases, people become less active and choose activities with less energetic demands that decrease physical fitness and functional capacity. The purpose of this study was to investigate the behavior of the functional capacity components after 12 weeks of weight training and stretching session on elderly women. Sixty subjects in the mean age of 65,66 (±4,73) years old, mean stature of 156,42 (±6,13) cm and mean body mass of 61,76 (± 9,14) kg were divided in resistance training group (TG) and stretching group (SG). The TG followed a weight training program during 12 weeks with 3 weekly sessions in alternated days while the SG performed 2 weekly stretching sessions of thirty minutes each for the major muscle groups. The functional capacity tests were: 30 seconds chair-stand, arm curl, 10 m walking and 8-foot-up and go. The statistic analysis used the Student t Test (p ≤ 0,05). The results indicated significant increase in all tests for the TG (p < 0,05) and arm curl for SG (p = 0,00). In conclusion, a weight training program developed on major muscle groups can be used for the welfare of physically independent elderly women.

ABSTRACT

O objetivo deste estudo foi analisar o perfil morfológico de culturistas brasileiros de elite que competiram no XXVII Campeonato Brasileiro de Culturismo-Musculação. Um total de 28 atletas (27,0 ± 7,4 anos; 78,2 ± 8,7kg; 170,1 ± 6,9cm), do sexo masculino, foram voluntariamente estudados. Medidas antropométricas (massa corporal, estatura, espessura de dobras cutâneas, perímetros e diâmetros) foram coletadas de todos os sujeitos no período da manhã, no dia da competição. Os valores estimados da composição corporal dos atletas foram os seguintes: gordura corporal relativa, 5,8 ± 0,5 por cento; massa corporal magra, 73,6 ± 8,2kg; massa muscular, 54,3 ± 6,7kg; área muscular do braço, 108,51 ± 15,19cm². Por outro lado, o somatótipo médio encontrado foi: endomorfia, 1,11 ± 0,29; mesomorfia, 8,26 ± 0,67; ectomorfia, 0,95 ± 0,53 (mesomorfo balanceado). Além de os culturistas apresentarem elevados níveis de desenvolvimento muscular (~70 por cento) e baixos depósitos de gordura corporal, verificou-se uniformidade nos acúmulos de gordura localizada. A predominância do componente mesomorfo confirmou a estrutura muscular acentuadamente desenvolvida encontrada nos atletas investigados. Portanto, os resultados do presente estudo demonstram que atletas de culturismo de elite apresentam no dia da competição grande volume muscular, bem como excelente definição muscular, proporcionalidade e simetria.


The aim of this study was to analyze the morphological profile of elite Brazilian bodybuilders who participated in the XXVII Brazilian Championship of Body Building. A total of 28 male athletes (27.0 ± 7.4 years; 78.2 ± 8.7 kg; 170.1 ± 6.9cm), were voluntarily assessed. Anthropometric measures (body mass, stature, skinfolds thickness, perimeters and diameters) were collected from all subjects in the morning shift, at the competition day. The estimated values of the body composition of the athletes were the following: relative body fat, 5.8 ± 0.5 percent; lean body mass, 73.6 ± 8.2 kg; muscular mass, 54.3 ± 6.7 kg and arm muscular area, 108.51 ± 15.19 cm². Conversely, the mean somatotype found was: endomorphy, 1.11 ± 0.29; mesomorphy, 8.26 ± 0.67; ectomorphy, 0.95 ± 0.53 (balanced mesomorphy). Besides high levels of muscular development (~70 percent) and low body fat buildup, the bodybuilders also presented uniformity in the accumulation of located fat. Predominance of the mesophormic component confirmed muscular structure remarkably developed found in the investigated athletes. Therefore, the results of the present study demonstrate that elite body building athletes present large amount of muscular volume, as well as excellent muscular definition, proportionality and symmetry at the day of the competition.
