Efeitos de um programa de exercícios resistidos periodizado de forma ondulatória na composição corporal de adultos e idosos

Abstract

Abstract - Aging is a natural process that causes changes in body composition, directly affecting health and quality of life, promoting muscle decline and the accumulation of body fat. On the other hand, the literature points to resistance exercise as effective in preventing and/or attenuating this process. Objective: To verify the effect of a periodized, undulating resistance exercise program on the percentage of fat and lean mass in adults and elderly individuals. Method: An uncontrolled intervention study was conducted with 44 adults and elderly individuals, with a median age of 66,3 (61,9 – 70,2) years. A 12-week, periodized, undulating resistance exercise intervention program was applied, with two weekly sessions. Pre and post-intervention body composition was estimated using perimetry technique. Results: A subtle decrease in the percentage of body fat in the sample was observed (from 39,9% to 39,4%), a slight increase in total body mass (from 42,5 kg to 42,9 kg), and a statistically significant increase in lean body mass (from 42,5 kg to 42,9 kg; p=0.044). Conclusions: The 12-week periodized undulating resistance exercise program was effective in promoting a statistically significant increase in lean body mass in adults and the elderly.
