It was our objective tTo compare the neuromuscular efficiency (NME) adaptations between resistance exercise methods (with and without pre-activation of the antagonist’s muscles) after six-weeks training. This randomized controlled trial assigned forty-nine men (mean age 20.9 ± 2.2 years; height 1.80 ± 0.1 m; body mass 75.0 ± 8.2 kg) into two groups: 1) Reciprocal Training group (RT, concentric knee flexion immediately followed by concentric knee extension at 60°.s-1); and Conventional Training (CT, concentric knee extension exercise). Both training adopted three sets, 10 repetitions at 60°.s-1, 2 days/week for 6 weeks. NME of knee extension and flexion were assessed pre and post-training. The groups were similar at baseline, for all variables. We found significant effects on NME only for the rectus femoris muscle in the RT group (ES = 0.31; 95%CI [0.30-0,92]; p<0.01). There were no significant differences at NME pre- and post-training in CT and Total Work did not differ between groups. Reciprocal training provided better neuromuscular efficiency, but effects were limited to the rectus femoris muscle. The small effect sizes suggest caution in the results.

Introduction: Quality of life (Qol) can be defined as the perception of well-being resulting from a set of individual and socio-environmental parameters. QoL can be divided into three fundamental aspects: subjectivity, multidimensionality and presence of positive and negative dimensions. According to WHOQOL GROUP, Qol relates the individual's perception of his life in the context of the culture and values in which he lives in relation to his/her goals, expectations and concerns. Physical, psychological, social, spiritual life, level of independence are factors that can influence QoL. Active aging has become increasingly common, experts from all areas of health recommend physical exercise as prevention and control of physiological deficits because of aging. Objective: To analyze the quality of life of elderly practitioners of physical exercise in the city of Goiânia-GO. Methodology: Cross-sectional study carried out in different academies in the city of Goiânia-Go. Eighty-seven elderly practitioners and non-practitioners of physical exercise were evaluated using the Qol questionnaire - WHOQOL - OLD). The data were analyzed using the Student's t-test for comparisons of means between two groups. The significance adopted was 5%. Results: In the domain, sensory ability and past activity present and future there were significant differences between the groups practicing and non-practicing exercise, being p=0.00 and p=0.05, respectively. Variable aas, social participation and death and dying were not found significant differences between the groups (p>0.05). Conclusion: Elderly practitioners of physical exercises have a higher quality of life when compared to nonpracticing elderly. The domains, sensory ability and past activity present and future were the factors that demonstrated the importance of exercise practice.

Introduction: Quality of life (QL) can be defined as a perception of well-being resulting from a set of individual and socio-environmental parameters. QV can be divided into three fundamental aspects: subjectivity, multidimensionality and the presence of positive and negative dimensions. According to the WHOQOL GROUP, QL is related to the individual's perception of his life in the context of the culture and values in which he lives in relation to his own, expectations and concerns. Domain, psychological, social life, spiritual independence are physical factors that can influence QL. Functional aging is increasingly common, health experts recommend physical exercise as a prevention and control of physiological deficiencies due to all the causes of aging in the areas. Objective: To analyze the quality of life of elderly practitioners of physical exercise in the city of Goiânia-GO. Methodology: Cross-sectional study carried out in different gyms in the city of Goiânia-GO. Eighty-seven elderly practitioners and non-practitioners of physic were from the QV exercise - WHOQOL - OLD). Data were analyzed using Student's t test for comparisons of means between two groups. The calculated significance was 5%. Results: No domain, sensory ability and activity present significant differences between the practical and non-practical exercise groups, with p=0.00 respectively and p=0.05. The variables, social participation and death and no significant difference was found between the groups (p>0.05). Conclusion: Elderly people who practice physical exercises have a better quality of life when compared to elderly people who do not practice physical exercises. The domains, sensory ability and activity present in the future the factors that are important in the practice of exercise.

Introdução: O envelhecimento é algo inerente a qualquer indivíduo, muitas vezes é encarado com receios e preconceitos. O processo do envelhecimento provoca perda gradativa da funcionalidade, tornando o indivíduo inapto a realizar as suas atividades de vida diárias (AVD). Objetivos: Avaliar a influência do treinamento de força e da hidroginástica na manutenção da funcionalidade de indivíduos idosos que residem em Goiânia - Go. Métodos: O presente estudo é caracterizado por um desenho transversal descritivo. Participaram do estudo trinta voluntários de ambos os sexos. Os voluntários foram divididos em três grupos. A) praticantes de musculação (n = 10), B) praticantes de hidroginástica (n =10) e grupo controle (não praticante de exercícios físico) (n = 10). Todos os voluntários passaram pelos critérios de inclusão e exclusão, em seguida foi aplicado o questionário índice de Katz e por fim foi desenvolvido o teste Time Up and Go Test (TUG). O teste Shapiro-Wilk confirmou a não normalidade dos dados. Assim, utilizou-se o teste Friedman com pos hoc com comparações múltiplas pelo teste Mann Whitney. A significância adotada foi de 5% (P<0,05). Resultados: No teste TUG houve diferenças significativas ao comparar os praticantes de musculação (p=0,001) e hidroginástica (p=0,000) com o grupo controle. No entanto, não houve diferenças significativas ao comparar os praticantes de musculação com os da hidroginástica (p=1,00). No Índice de Katz, não houve diferenças significativas (p>0,05) entre os três grupos (musculação, hidroginástica e controle). Ambos os grupos tiveram a pontuação escalar máxima do teste. Conclusão: O presente estudo demonstrou que a prática de exercícios físico proporciona melhora na funcionalidade dos indivíduos idosos.
