Abstract
ObjectiveThe aim of this study was to investigate the influence of different categories of dietary supplements on the body composition of resistance-training practitioners. MethodsParticipants of both sexes and ages 20 to 59 y participated in this cross-sectional study. The use of dietary supplements was investigated and classified into three categories: sports foods, medical supplements, and ergogenic supplements. One-way analysis of covariance adjusted for age, type of exercise, frequency of exercise, total amount of daily exercise, and exercise intensity was used in the analysis. ResultsOf 427 participants, 278 (65%), were supplement consumers. Women who consumed sports foods had higher percentages of skeletal muscle (P = 0.014) and lower percentages of body fat than women who did not take supplements (P = 0.031). Furthermore, women who used medicinal supplements had greater visceral fat levels than women who did not (P = 0.019). No significant differences were found between type of supplement used and body composition among men (P > 0.05). ConclusionsConsuming sports foods was associated with higher percentages of skeletal muscle and lower percentages of body fat; women who used medical supplements had higher visceral fat levels.
