ABSTRACT

A goleira de handebol detém uma série de particularidades quando comparada às demais posições. Mesmo chamando atenção por exercer funções defensivas, sua participação no ataque pode ter elevada importância. Este estudo objetivou descrever a percepção de treinadores de equipes femininas de handebol da categoria cadete (sub-16) sobre a função da goleira, identificando suas preferências quanto ao treinamento, especificidades da posição e sua concepção sobre a goleira na fase ofensiva de jogo.Participaram do estudo cinco treinadores da maior liga do estado de São Paulo. O método se baseou em uma pesquisa qualitativa, sendo utilizadas entrevistas estruturadas com seis perguntas. Os dados obtidos foram tabulados e analisados de acordo com o método do Discurso do Sujeito Coletivo (DSC). Os treinadores evidenciaram a importância da goleira na fase ofensiva, destacando seu papel na reposição de bola rápida e na ligação de contra-ataques, e a possibilidade de exercer a função de goleira-linha. Também foi evidenciada a necessidade de boa comunicação entre a goleira e as jogadoras de linha. Parte dos treinadores destacou que uma goleira que contribui com qualidade à fase ofensiva pode ser um diferencial em jogos decisivos. Ademais, alguns treinadores destacaram a importância do treinamento específico para as goleiras, sendo o treino pautado em situações de jogo uma possibilidade interessante para o desenvolvimento de competências específicas, além de trabalhar a interação entre a goleira e as demais companheiras. Concluímos que a goleira tem uma função fundamental também na fase ofensiva, sendo necessário um processo de treinamento pautado no jogo que a prepare para também desempenhar esse papel....(AU)


The goalkeeper of handball has a number of particularities when compared to other positions. Even having attention because his/her defensive functions, his/her participation in the attack may be of great importance. This study aimed to describe the perception of coaches of women's handball teams of the cadet category (under-16) on the goalkeeper's function, identifying their preferences regarding training, position specificities and their conception of the goalkeeper in offensive game phase. Five coaches from the biggest league in the state of São Paulo participated in this study. The method was based on a qualitative research, using structured interviews with six questions. Data were tabulated and analyzed according to the Collective Subject Discourse (CSD) method. The coaches showed the importance of the goalkeeper in the offensive phase, highlighting their role in fast ball replacement and the connection of fast breaks, and the possibility of exercising the goalkeeper-line function. It was also highlighted the good communication between the goalkeeper and the other players. Some coaches pointed out that a goalkeeper who contributes with quality to the offensive phase can be a differential in decisive games. In addition, some coaches emphasized the importance of specific training for goalkeepers, with training based on game situations an interesting possibility for the development of specific competences, besides of working the interaction between the goalkeeper and the other teammates. We conclude that the goalkeeper has a fundamental function on the offensive phase, requiring a process of training based on the game that prepares her to also play this role....(AU)

ABSTRACT

The use of technology has increased tremendously, by means of more reliable, smaller, more accessible and specially more user-friendly devices, which provide a wider range of features, and promote significant benefits for the population and health professionals. It is in this context that monitors and apps for heart rate (HR) measurement have emerged. HR is a clinical vital sign of diagnostic and prognostic importance. In response to body movement, HR tends to increase, in a direct relationship with the intensity of exercise. HR was primarily measured by the count of arterial pulse, and recently, HR can be precisely measured by monitors, bracelets and smartphone apps capable to perform real-time measurements and storage of data. This paper aimed to make a brief and updated review on the theme, providing a broader view of advantages and limitations of these resources for HR measurement in exercise. HR monitors and apps use basically two types of technology, optical sensor (photoplethysmography) and electrical signal from the heart. In general, these devices have shown good accuracy in measuring HR and HR variability at rest, but there are differences between brands and models considering the type, mode and intensity of exercise. HR measurements by monitors and smartphone apps are simple, accessible and may help cardiologists in the monitoring of the intensity of aerobic exercise, focusing on health promotion and on primary and secondary prevention of cardiovascular diseases

ABSTRACT

The motor activity belongs to controllable factors that influence human health because it ensures disease prevention. Analysis of scientific publications has revealed that motor activity of adult people is insufficient; this leads to the development of hypodynamia and worsens health. The level and nature of motor activity should correspond to the peculiarities of the body (age, gender, functional state, physical fitness, etc.). This problem requires the study of the relationship between the motor activity of the adult men and women and their indicators of physical fitness and functional state of the body. The relationship between the motor activity and indicators dependent on it has been reviewed in the article. The impact of the motor activity on the functional state of the body and physical fitness has been determined. The results have led to a conclusion that the motor activity of adults should be analyzed along with the study of indicators of functional state and physical fitness.

ABSTRACT

O sucesso do mercado de academia de musculação e seu consequente crescimento necessitam de profissionais capacitados na área da gestão, com conhecimento em marketing, finanças, administração e gerenciamento. Dentre as inúmeras áreas que o profissional formado em Bacharelado em Educação Física pode atuar, o enfoque deste trabalho está no segmento de Personal Trainer (PT). Esta demanda abre uma grande oportunidade e procura pelo serviço dos PTs, sendo que as pessoas procuram estes com vários objetivos, como: qualidade de vida, status, preparação física, dentre outros. O crescimento no número de oportunidades de trabalho ao PT é compatível com o ascendente número de profissionais atuantes no mercado, logo "preparação" e "qualificação" são diferenciais para obter melhores retornos financeiros. Sendo assim, o objetivo deste trabalho foi de apresentar o atual perfil da gestão do negócio do PT atuante em Curitiba/PR. Foi realizada uma pesquisa descritiva quantitativa, através da aplicação de um questionário com 282 participantes, dos quais apenas 262 foram credenciados para a pesquisa. As constatações principais foram que no setor de gestão de pessoas os profissionais estão preocupados em fazer atualizações e/ou cursos na área, além de buscarem fazer de alguma maneira uma avaliação de seu trabalho com seus clientes. Em relação ao marketing observou-se que os profissionais pretendem fidelizar seus clientes, porém, não realizam pacotes de aderência, o que seria recomendável; além disso, se preocupam em saber o motivo da desistência de seus serviços por parte de seus clientes, contudo não possuem um padrão para estipular o preço de seus serviços ficando, portanto, vulnerável ao mercado. Por fim, a gestão financeira também carece de maior preocupação haja vista que poucos profissionais confeccionam planilhas de gastos, formalizam contratos com os clientes ou preocupam-se com seus planos de previdência....(AU)


The success of the fitness market and its consequent growth needs trained professionals in the area of management with knowledge in marketing, finance, administration and management. Among the many areas that the professional degree in Bachelor of Physical Education can act, the focus of this work is in the Personal Trainer (PT) segment. This demand opens a great opportunity and demand for the service of PTs, where people seek these for various purposes, such as quality of life, status, physical preparation, among others. The growth in the number of job opportunities for personal trainer is compatible with the growing number of professionals working in the market, so "preparation and qualification" are differential for better financial returns. Thus the aim of this study was to show the current profile of the business management of the active PT in Curitiba/PR. A quantitative descriptive research, by applying a questionnaire with 282 participants, of which only 262 were accredited for research. The main findings were that in people management industry professionals are concerned to make updates and / or courses in the area, in addition to seeking to somehow an evaluation of its work with its customers. Regarding marketing, it was observed that the professionals intend to keep their customers loyal, but they do not carry out adherence packages, which would be advisable. In addition, professionals are concerned about the reason for the abandonment of their services from their customers, however, they do not have a standard to stipulate the price of their services, and is therefore vulnerable to the market. Finally, financial management is also of greater concern since few professionals prepare a spreadsheet, formalize contracts with clients, or care about their pension plans....(AU)

ABSTRACT

ABSTRACT In order to overcome the limitations and negative perceptions often addressed to coach education programs, the sports coaching literature has offered important contributions for its improvement. Thus, through analyzing scientific articles published between 2009 and 2015, this study aimed to identify the teaching strategies adopted in small-scale, large-scale, and university-based programs. An automatic search for articles was conducted in the following databases: PUBMED, SCOPUS, Web of Science, PyscNET, and SPORTDiscus. Manual search was conducted in two non-indexed peer-reviewed journals. Afterwards, 731 articles were found and 16 were selected by applying the established criteria. The results indicated that most of the studies selected took place in a university-based context. In relation to the teaching strategies adopted, we verified a common intent to engage coaches in group discussions and reflection activities. Based on the articles analyzed, we suggest that the teaching strategies adopted in coach education programs indicate a trend towards learner-centered approaches (coach-centered), meeting the international guidelines for the improvement and effectiveness of these endeavors.


RESUMO De modo a superar as limitações e percepções negativas atribuídas por treinadores esportivos aos programas de formação, estudos recentes têm contribuído com importantes direcionamentos para seu aprimoramento. Assim, por meio da análise de artigos científicos publicados entre 2009 e 2015, este estudo buscou identificar as estratégias de ensino adotadas em programas de formação de treinadores de pequena escala, larga escala e universitários. A busca automática por artigos foi realizada nas bases de dados PUBMED, SCOPUS, Web of Science, PyscNET e SPORTDiscus, e a busca manual realizou-se em dois periódicos não indexados. Na busca inicial foram encontrados 731 estudos e, por meio da aplicação dos critérios de exclusão estabelecidos, 16 foram selecionados. Os resultados indicam que a maior parte dos estudos concentra-se nos programas universitários. Com relação às estratégias de ensino utilizadas, percebeu-se, de maneira geral, a utilização de estratégias que priorizam o engajamento dos treinadores esportivos em atividades que envolvem discussões em grupo e a reflexão. Com base nos artigos analisados verificou-se que as estratégias de ensino adotadas nos programas de formação de treinadores apontam pela tendência da adoção de abordagens centradas no aprendiz (treinadores), indo ao encontro das orientações internacionais para o aperfeiçoamento e a efetividade destas iniciativas.

ABSTRACT

Abstract Aim: To determine how EMG, anthropometric, and psychological factors, and physical activity levels affect isokinetic peak torque performance (IPT) of multiple set exercise sessions. Methods: 20 participants (27±7 years old), classified as active (A=10) and inactive (I=10), performed 10x10:40secs of maximal unilateral knee flexions and extensions at 120o.s-1. The IPT, EMG, glucose, LDH, and lactate concentrations and perceptions of pain, effort, recovery. Results: Active volunteers showed higher muscularity (52±5 vs 47±4 cm; p<0.05), PTI (262±4 vs 185±4 Nm; p<0.05), relative lower drop in performance (14±2 vs 27±3% ; p<0.05), major MDF (83±1 vs 76±1 Hz; p<0.05), lower log -Fins5 (-12.9±0.3 vs -12.7 ± 0.3 Hz; p<0.05), smaller subjective perception of effort (14.8±0.3 vs 17.0±0.3) and higher subjective perception of recovery (14.2±0.2 vs 12.3±0.3). There was a significant interaction between relative fatigue and the number of sets (F=6.18; p<0.001). Stepwise multiple regressions revealed that subjective perception of recovery best explained the fatigue level generated in the active volunteers [fatigue level= 85.084-5255(SPR)] while for body mass was the best determinant for the inactive group [fatigue level = -21.560 +1.828(BMI)]. Conclusion: Data from the present analysis suggest that physically active individuals show higher torque development and a smaller fatigability index when compared to inactive individuals. Among the fatigue models studied, it is possible that alterations in biochemical components, psychophysiological and EMG are not sensitive to the direct influence of the fatigue dynamics protocol, both in active or inactive individuals.

ABSTRACT

Abstract Introduction: Sedentary behavior (SB) has been described as an independent risk factor for health, regardless of the recommended amount of moderate-to-vigorous physical activity (MVPA). However, SB and MVPA as predictors of falls have been poorly investigated. Objective: To compare the associations between SB and MVPA and the occurrence of falls in middle-aged and older adults. Method: The participants wore a triaxial accelerometer over the dominant hip for seven days to measure SB and MVPA. The occurrence of falls and cardiovascular risk factors were assessed by self-report. Isokinetic peak torque (PT) of knee extension, peak oxygen uptake (V'O2) in a ramp treadmill protocol, and lean (LBM) body mass and body fat (BFM) (bioelectrical impedance) were also assessed. The critical roles of SB and MVPA on the occurrence of falls were compared by multiple logistic regression adjusted for age, sex, cardiovascular risk factors, LBM, peak V'O2, and PT of knee extension. Results: 379 participants were evaluated, aged 40-80 years. Forty-eight participants reported at least one fall in the previous 12 months (14.5%). Fallers presented lower SB and higher MVPA. They were predominantly women and older adults with lower physical fitness. After multivariate analysis, MVPA, but not SB, was selected as an independent predictor of falls, increasing the odds ratio of having a fall (1.184, 95% confidence interval, 1.016 - 1.378). Conclusion: Episodes of falls in predominantly middle-aged and women subjects were associated with a higher amount of MVPA, not the opposite, indicating an adverse effect of MVPA in these subjects.


Resumo Introdução: O Comportamento sedentário (CS) tem sido descrito como fator de risco independente para saúde, a despeito da recomendação de atividade física moderada a intensa (AFMI). Contudo, pouco foi investigado se CS e AFMI são preditores da ocorrência de quedas. Objetivo: Comparar as associações entre CS e AFMI e a ocorrência de quedas em adultos de meia-idade e idosos. Método: Os participantes usaram acelerômetro triaxial no quadril dominante por sete dias para obtenção de CS e AFMI. A ocorrência de quedas e o risco cardiovascular foram avaliados através de autorrelato. Avaliamos o pico de torque (PT) isocinético da extensão de joelho, o pico de consumo de oxigênio (V'O2) em protocolo de rampa na esteira, e massa magra (MMC) e gordura (GC) corporais (bioimpedância elétrica). Comparamos o papel de CS e AFMI na ocorrência de quedas através de regressões lineares múltiplas ajustadas por idade, sexo, fatores de risco para doença cardiovascular, MMC, V'O2 pico, e PT da extensão de joelho. Resultados: Avaliamos 379 participantes de 40 - 80 anos. Quarenta e oito participantes reportaram, pelo menos, uma queda nos 12 meses anteriores ao estudo (14.5%). Os caidores apresentaram menor CS e maior AFMI. Eles eram predominantemente mulheres e idosos com menor aptidão física. Após as análises multivariadas, AFMI foi selecionada como preditor independente da ocorrência de quedas, aumentando o odds ratio de cair (1.184, 95% intervalo de confiança, 1.016 - 1.378). Conclusão: Os episódios de quedas, sobretudo em mulheres de meia-idade, foram associados com maior AFMI, indicando efeito adverso da AFMI nestes sujeitos.


Resumen Introducción: El comportamiento sedentario (CS) se ha descrito como un factor de riesgo independiente para la salud, independientemente de la cantidad recomendada de actividad física moderada a vigorosa (AFMV). El CS y el AFMV como predictores de caídas fueron poco investigados. Objetivo: Comparar las asociaciones entre CS y AFMV, y la ocurrencia de caídas en adultos de mediana edad y mayores. Método: Los participantes usaron un acelerómetro triaxial durante siete días para medir CS y AFMV. La ocurrencia de caídas y factores de riesgo cardiovascular se evaluaron mediante autoinforme. Se evaluó el torque máximo isocinético (TM) de la extensión de la rodilla, el consumo máximo de oxígeno (V'O2) en un protocolo de rampa en la estera, y masas corporales magra (MMC) y grasa (GC) (impedancia bioeléctrica). Comparamos los papeles de CS y AFMV en la ocurrencia de caídas mediante la regresión logística múltiple ajustada por edad, sexo, factores de riesgo cardiovascular, MMC, pico de V'O2 y TM de la extensión de la rodilla. Resultados: Se evaluaron 379 participantes de 40 - 80 años. Cuarenta y ocho participantes informaron al menos una caída en los 12 meses previos (14,5%). Caedores presentaron menor CS y mayor AFMV. Eran predominantemente mujeres y mayores con menor aptitud física. Después de los análisis multivariados, AFMV, pero no CS, fue seleccionada como predictor independiente de caídas, lo que aumentó la odds ratio de tener una caída (1.184, intervalo de confianza del 95%, 1,016 - 1,378). Conclusión: los episodios de caídas en mujeres de mediana edad se asociaron con mayor AFMV, lo que indica un efecto adverso de AFMV en estos sujetos.

ABSTRACT

O objetivo do estudo foi avaliar os efeitos do treinamento pliométrico (TP) sobre a força explosiva (FE) e a potência (PT) de membros inferiores em 72 meninas púberes, praticantes de voleibol, idades 12,18±1,27 anos, Estatura 1,56±0,08 m, % de gordura 24,32±6,7 e massa corporal =48,18±11,28 kg. Todas se encontravam no estágio de maturação púbere, segundo método de Tanner. A amostra foi dividida em dois grupos: Grupo Controle - GC n=48 que realizou 3 sessões semanais de voleibol, e Grupo Experimental - GE n=24, que realizou além das 3 sessões semanais de voleibol, mais 3 sessões semanais de TP durante 8 semanas, as sessões constavam de multisaltos, saltos sobre barreiras e saltos profundos com alturas entre 20 e 60 cm, as avaliações da FE e PT. Para controle da FE e da PT foram utilizados os seguintes procedimentos: SJ (Squat jump), CMJ (Counter Moviment Jump) e DJ (Drop Jump). O GE apresentou uma melhora de 0,59 cm no SJ (19,12 ± 4,03 ­ 19,71 ± 3,93) o que representa um aumento de 3,08%, enquanto que no CMJ o aumento foi de 0,64 cm (19,88 ± 3,76 ­ 20,52 ± 4,26) que significa uma melhora de 3,21% entre o pré e o pós treinamento. Os resultados do GE apresentaram melhoras não significativas, o que demonstra uma tendência positiva do TP sobre a FE e a PT em meninas púberes praticantes de voleibol...(AU)


The aim of this study was to evaluate the effects of plyometric training (PT) on explosive strength 1 and power (PR) of the lower limbs in 72 pubertal girls volleyball players aged 12.18 ± 1.27 years, Height 1.56 ± 008 m, body fat 24.32 ± 6.77 and body mass = 48.18 ± 11.28 kg. All were in stage of pubertal maturation in the stage of pubertal maturation according to the method Tanner. Divided into two groups: Control Group - CG n = 48, held three sessions per week of volleyball and Experimental Group - EG n = 24, which held in addition of 3 weekly sessions of volleyball, more 3 weekly sessions of PT during 8 weeks, that comprised the multi jump, jump over hurdle and drop jumps with heights between 20 cm and 60 cm, the assessments of ES and PR occurred pre and post-training with an interval of 8 weeks. To assess the ES and PR the following procedures were used: SJ (squat jump), CMJ (Counter Movement Jump) and DJ (Drop Jump). The EG presented an improvement of 0.59 cm in SJ (19.12 ± 4.03 - 19.71 ± 3.93) which represents an increase of 3.08%, while in the CMJ the increase was 0.64 cm (19.88 ± 3.76 - 20.52 ± 4.26) which means an improvement of 3.21% between the pre and post training. The results of the GE presented improvements were not significant, which shows a positive effect of PT on the ES and PR in the pubertal girls practicing volleyball...(AU)

ABSTRACT

Existe escasa información respecto a la relación entre los parámetros antropométricos y la funcionalidad motriz en sujetos activos e inactivos. En ese sentido, la presente investigación pretende determinar la relación entre las características antropométricas y la puntuación de funcionalidad motriz en sujetos chilenos con distintos niveles de actividad física. La muestra incluyó 63 sujetos (20 mujeres), distribuidos en tres grupos: grupo físicamente activo (GFA, n=21), grupo deportista (GD, n=21) y grupo físicamente inactivo (GFI, n=21). Las variables estudiadas correspondieron a la composición corporal, perímetro de cintura (PC), índice de masa corporal (IMC), índice cintura-cadera (ICC) y funcionalidad motriz a través del Functional Movement Screen (FMS). Se aplicó Anova una vía, el test de Pearson y un modelo de regresión lineal múltiple, considerando un p <0,05. Los resultados indican correlaciones moderadas e inversas entre la puntuación FMS y la sumatoria de pliegues cutáneos, Zadiposidad, masa adiposa (kg) e IMC en el GFI (-0,52 ≤ r ≤ -0,62), y con la sumatoria de pliegues cutáneos, masa adiposa (kg y %) en el GFA(-0,54 ≤ r ≤ -0,60). Los cambios en la puntuación del FMS se explican principalmente por la suma de pliegues cutáneos, la Zadiposidad, la masa grasa (kg), el porcentaje de masa grasa y el PC. En conclusión, las características antropométricas y la funcionalidad motriz se encuentran asociadas en sujetos chilenos físicamente activos (GFA) e inactivos, mostrando una relación inversa entre el puntaje del FMS con los parámetros de la composición corporal relacionados con la adiposidad(AU)


There is little information about the relationship between anthropometric indexes and motor function in active and inactive subjects. In that sense, this research aims todetermine the relationship between anthropometric characteristics and motor function score in Chilean subjects with different levels of physical activity. The sample included 63 subjects (20 women), allocated into three groups:physically active group (GFA, n=21), athlete group (GD, n=21) and physically inactive group (GFI, n=21).The variables studied were body composition, waist circumference (WC), body mass index (BMI), waist-to-hip ratio (WHR), and motor functionality using the Functional Movement Screen (FMS). A One-way ANOVA, Pearson’s correlation test, and a multiple linear regression model were applied, considering P <0.05.The results showed a moderate inverse correlation (-0.52 ≤ r ≤ -0.62)between FMS score and sum of skin folds, Z-score fat, fat mass (Kg), BMI in the GFI. Similarly, in the GFA the FMS showed a moderate inverse correlation (-0.54 ≤ r ≤ -0.60) with the sum of skin folds, fat mass (Kg& %). Changes in the FMS score were mainly explained by the sum of skin fold, Z-score fat, fat mass (kg), percentage of fat mass and WC. In conclusion, anthropometric characteristics are associated with motor function in physically active (GFA) and inactive Chilean subjects, showing an inverse relationship between the FMS score and adiposity parameters of body composition(AU)

ABSTRACT

The purpose of the present study was to assess muscle overload through changes in creatine kinase (CK) activity and serum concentration of α-actin in soccer players in response of two months of pre-season physical training. Basic procedures: Ten professional athletes (26 ± 6 years of age) undergoing arduous training were evaluated. Serum CK activity and α-actin serum concentration were determined at the beginning and end of two months of pre-season training. Effort intensity was determined throughout the training sessions by monitoring heart rate (HR). Serum CK activity was determined using the colorimetric method. Plasma α-actin concentration was evaluated using ELISA and confirmed using the Western Blot method. Main Findings: Serum CK activity and α-actin concentration were higher in the post-training period in comparison to the pre-training period (CK: PRE 65.5 ± 4.2 U/L, POST 435.7 ± 70.0 U/L, p=0.0004; α-actin by Western Blot: PRE 42.9 ± 21.6 µg/mL, POST 68.1 ± 19.1 µg/mL, p=0.0004; by ELISA: PRE 70.63 ± 10.4 µg/mL, POST 101.80 ± 17.3 µg/mL, p=0.0125). Conclusions: The significant increases in α-actin concentration and in CK activity of soccer players over the two-month pre-season indicated that an elevated training overload was imposed upon the athletes.(AU)


O objetivo do presente estudo foi avaliar a sobrecarga muscular através de mudanças na creatina quinase (CK) e concentração sérica de α-actina em jogadores de futebol de resposta de dois meses de treinamento físico de pré-temporada. Procedimentos básicos: Dez atletas profissionais (26 ± 6 anos de idade) que se submeteram aos treinamentos foram avaliados. Atividade de CK e concentração sérica de actina-α foram determinados no início e no fim de dois meses de treinamento de pré-temporada. Intensidade de esforço foi determinada ao longo das sessões de treinamento por meio do monitoramento da freqüência cardíaca (FC). Actividade de CK no soro foi determinada pelo método colorimétrico. Concentração de plasma α-actina foi avaliada utilizando ELISA e confirmado usando o método de Western Blot. Conclusões: a atividade da CK sérica e concentração α-actina foram maiores no período pós-treinamento em comparação com o período pré-treinamento (CK: PRE 65,5 ± 4,2 U/L, 435,7 ± 70,0 POST U/L, p = 0,0004; α-actina por Western Blot: PRE 42,9 ± 21,6 ng/mL, 68,1 ± 19,1 POST mcg/mL, p = 0,0004; por ELISA: PRE 70,63 ± 10,4 ng/mL, POST 101,80 ± 17,3 ng/mL, p = 0,0125). Conclusões: O aumento da atividade da CK e da concentração de actina-α após dois meses de treinamento na pré-temporada de um time de futebol indica uma sobrecarga muscular significativa imposta por este período de treinamento.(AU)
