Abstract

O estudo teve como objetivo analisar o efeito de dois diferentes volumes de alongamento, 90 ou 180 segundos, na capacidade funcional (CF) de idosas. Participaram deste estudo, 43 mulheres idosas divididas em tres grupos: Grupo Controle inativo (GC, n=14), Grupo Treinamento com tres series de 30 segundos (GT90, n=15) e Grupo Treinamento com tres series de 60 segundos (GT180, n=14). Os grupos GT90 e GT180 frequentaram a universidade durante 16 semanas, tres vezes por semana. O protocolo de treinamento consistiu em sete diferentes exercicios de alongamento estatico, realizados de forma ativa. O GC frequentou a universidade apenas nos periodos de avaliacao. As avaliacoes dos componentes da CF e do Indice de Aptidao Funcional Geral (IAFG), dos tres grupos, foram realizadas tanto no momento pre, quanto apos oito e 16 semanas de experimento, por meio de uma bateria de testes motores. A ANOVA two-way apontou interacao grupo x momento significante para os componentes flexibilidade, resistencia de forca muscular e resistencia aerobia, e para valores do IAFG (p < 0,05). O teste post hoc de Scheffe apontou diferenca entre os grupos treinamento e o GC, sem nenhuma diferenca entre GT90 e GT180. Houve, tambem, melhora na classificacao geral do IAFG para o GT90 e GT180, que passaram de regular para bom, enquanto o GC manteve-se classificado em regular. Pode-se concluir que os dois volumes de alongamento empregados foram igualmente eficazes na melhora da flexibilidade, resistencia de forca muscular, resistencia aerobia e nos niveis da CF de mulheres idosas.

Highlights

  • Functional capacity (FC) can be defined as the ability to carry out daily tasks with vigor, alertness, and without excessive fatigue[1]

  • From the results found in each motor test, it was assigned a percentile score, and the sum of the scores of all components resulted in the Global Functional Fitness Index (GFFI)

  • The results showed that the two stretching durations were effective in improving: a) flexibility, muscle strength and aerobic endurance; b) the mean values and the ratings of participants’ GFFI

Summary

Introduction

Functional capacity (FC) can be defined as the ability to carry out daily tasks with vigor, alertness, and without excessive fatigue[1]. This ability is operationalized through a set of components that include: cardiorespiratory fitness, flexibility, body composition, balance, agility, reaction time and muscular strength[1]. It is known that high levels of flexibility are directly related to the efficiency in the performance of activities of daily living[2,3,4]. There is a relationship between decreased flexibility and difficulties in performing activities of daily living, few studies have sought to investigate the effects of stretching training in the range of motion of the elderly population[6]. The authors found improvement in flexibility for the three groups that were trained, but the group that trained with longer duration (240 seconds) presented significantly higher values when compared to the two other durations (60 and 120 seconds) and to the inactive group
