Resumo
O treinamento da flexibilidade tem sido eficaz na melhora da amplitude de movimento articular e ainda, tem promovido melhora nos padrões da marcha, agilidade e força muscular. Entretanto, tendo em vista o reduzido número de estudos controlados e aleatorizados investigando os efeitos do citado treinamento na capacidade funcional (CF) de idosos, e a grande disparidade metodológica adotada, os resultados ainda são contraditórios. Desta forma, o objetivo deste estudo foi analisar os efeitos de um treinamento de flexibilidade na CF e seus componentes, em idosas viventes na comunidade. Para isso, foram selecionadas 31 mulheres idosas aleatoriamente distribuídas em dois grupos: a) Grupo Controle (GC, n=16), o qual realizou atividades artísticas e cognitivas; b) Grupo Treinamento (GT, n=15), o qual participou do treinamento composto por exercícios de alongamento, com três séries de 30 segundos, voltado para os principais grupos musculares. Ambos os grupos frequentaram a universidade três vezes na semana, durante oito semanas, com duração aproximada de uma hora por sessão. Para avaliação dos componentes da CF foi aplicada a bateria de testes motores da American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) e o teste de subir escadas (TSE). A partir da somatória dos resultados dos testes da AAHPERD foi calculado o índice de aptidão funcional geral (IAFG), o qual pode ser classificado de muito fraco a muito bom. O flexímetro foi adotado para avaliação angular da flexibilidade e a contração voluntária máxima isométrica (CVM), dos membros inferiores, foi avaliada pela extensão unilateral de joelho. O teste U Mann Whitney não apontou diferença entre os grupos para os valores do índice de aptidão funcional geral, porém o GT melhorou sua classificação pós-intervenção. Para os componentes da CF e TSE...
The flexibility training has been effective in improving the joint range of motion and promoting better gait patterns, agility and muscle strength. However, due to the small number of controlled and randomized studies that have investigated such training effects on the functional capacity (FC) of the elderly, and the large disparity between methodologies, the results are still contradictories. Therefore, the purpose of this study was to analyze the effects of flexibility training on the FC and its components in community dwelling older women. Thirty one older women enrolled in the study and were randomly assigned into two groups: a) Control Group (CG, n = 16), which performed artistic and cognitive activities; b) Training Group (TG, n = 15), which underwent a training protocol composed by stretching exercises, with three sets of 30 seconds, for the major muscle groups. Both groups visited the university three times a week, for eight weeks, lasting about one hour per session. For the assessment of the FC components it was applied the American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) motor tests battery and the stair climbing test (SCT). From the sum of the AAHPERD tests results it was calculated the global functional fitness index (GFFI), which can be rated from very poor to very good. The fleximeter was used to evaluate the angular flexibility and the isometric maximal voluntary contraction (MVC) of the lower limbs was assessed by a load cell during unilateral knee extension. The U Mann Whitney test did not pointed difference between the groups for general functional fitness index (GFFI) values. However, the TG improved its classification at post-intervention. Regarding the FC components and SCT the ANOVA showed significant Group vs. Moment interaction only for flexibility, when it was evaluated by... (Complete abstract click electronic access below)
