Abstract

Objective. The aim of this study was to evaluate the effect of a weight training program with imposed and self-selected intensity on the body composition of elderly.

Method. This randomized clinical trial included 43 sedentary elderly of both sexes. The elderly were randomized into 3 groups, the Imposed Intensity Group (IIG), the Self-selected Intensity Group (SIG) and the Control Group (CG). The training program lasted 16 weeks with two sessions per week. The IIG performed the training with an intensity of 60% of one repetition maximum and the SIG self-selected the intensity based on the descriptor +3 (good) from the Feeling Scale, while the CG performed only the evaluations. It was assessed body mass index (BMI), Fat Percentage (%Fat) and Arm Muscle Circumference (AMC) in moments Pre, Post 8 weeks and Post 16 weeks. The repeated-measures ANOVA was performed for intragroup comparisons and the one-way ANOVA for intergroup comparisons throughout the evaluations. The significance level was p<0.05.

Results. No significant differences were found in any of the studied variables, either intragroups or intergroups, at the different evaluation moments.

Conclusion. It was found that regardless of the form of intensity prescription, 16 weeks of weight training was not sufficient to generate statistically significant beneficial effects on the body composition of the elderly.
