Influência de um programa de atividade física de longa duração sobre a força muscular manual e a flexibilidade corporal de mulheres idosas

Abstract

Influence of a Long-Term Physical Activity Program on Hand Muscle Strength and Body Flexibility Among Elderly Women Objective: The present study evaluated the influence of a two-year physical activity program on muscle strength and body flexibility among non-institutionalized elderly women (60-80 years old), from Salamanca Province in Spain. Method: Thirty-two individuals were chosen to take part in the Geriatric Revitalization Program at Salamanca University. The selection criteria were that they should be female, between 60 and 80 years old, with an attendance rate of at least 74% in the physical activity program. There were 174 physical activity sessions, over a 58-week period, three times a week, lasting 50-55 minutes each. During this period, four measurements of hand muscle strength were made, using a pressure manometer, and also of body flexibility, using the sit and reach test. The data were analyzed using ANOVA with repeated measurements. Results: There were no significant differences in relation to either muscle strength or flexibility (p=0.005). Conclusions: The program contributed towards maintaining hand grip strength over the two-year period. For body flexibility, the data indicate the need to reprogram the exercises aimed at developing this capacity.
