Resumo
O Objetivo do estudo foi comparar os efeitos de um Treino da Força (TF) e
Exercício Combinado no Meio Aquático (EC), de 24 semanas, na capacidade
funcional em idosas. Este estudo contou com 41 mulheres com idade média de
67,02±6,08 anos, um massa corporal médio de 74,24±10,29 kg e altura média
de 154,71±5,67 cm. Foram divididas em três grupos: um em que executaram
24 semanas de TF (GF) (n=15); um que executou o mesmo período de EC
(GEC) (n=19); e um grupo de controlo (GC) (n=7) que continuaram com suas
atividades de vida diária. Foi avaliada a capacidade funcional das idosas no
início e no final das 24 semanas de treino, através dos testes propostos por
Rikli & Jones (1999), levantar e sentar na cadeira em 30s (LS), flexão do
antebraço (FA), sentado e alcançar (SA), levantar e caminhar 2,44m e voltar a
sentar (LCS), alcançar atrás das costas com as mãos (AM) e medidas
antropométricas com pré-teste, após completar as 12 primeiras e no final da
intervenção das atividades. Tanto o GF quanto o GH melhoraram a sua
performance na execução dos testes LS, LCS (24,20±3,63 vezes, 21,28±4,20
vezes, 3,93±0,4s, 4,50±0,92s, respectivamente, p<0,05). Somente o GF obteve
resultados significativos em FA e SA (25,73±2,74 vezes e 5,93±7,4
centímetros, respectivamente, P<0,05). O GC não obteve melhoria significativa
em nenhum dos testes aplicados. Este estudo sugere que tanto o GEC quanto
o TF, enquanto atividades orientadas promovem a melhoria significativa de
alguns testes que avaliam a autonomia funcional de idosas.
The aim of this study was to assess the effects of twenty-four weeks of strength and combined exercise in the aquatic environment on the functional capacity of aged women. This work involved 41 women with an average age of 67,02±6,08 years, an average body mass of 74,24±10,29 kg and an average height of 154,71±5,67 m. They were divided into three groups: one of them carried out a 24 weeks Strength Training (GF) (n=15), another carried out the same period of time of combined exercise in the aquatic environment (GEC) (n=19), and a control group (GC) (n=7) who kept on their daily routine activities. The functional capacity of the aged women was assessed at the beginning and at the end of the 24 weeks training period by means of the tests proposed by Rikli & Jones (1999): get up and sit on a chair in 30s (LS), forearm flexion (FA), sit and reach (SA), get up and walk 2,44m and sit again (LCS), reach behind their back with their hands (AM). Both GF and GEC improved their performance in the carrying out of the LS and LCS tests (24,20±3,63 times, 21,28±20 times, 3,93±0,4s, 4,50±92s, respectively, (p<0.05). Only GF had significant improvements in FA and SA (25,73±2,74 times and 5,93±7,4 cm, respectively (p<0,05). The GC had no significant improvement in any of the tests. This study suggests that both strength training and combined exercise in the aquatic environment, while oriented activities, promote a significant improvement in some tests which assess the functional capacity of old aged women.
