Abstract
Introduction: The use of dietary supplements and ergogenic aids (DSEA) is popular among physical activity enthusiasts. Particularly, resistance training (RT) practitioners represent important DSEA consumers due to its easy access and the appeal of claims related to muscle hypertrophy, aesthetics, and physical performance improvements.
Methods: Our aim was to study knowledge, prevalence, and profile of DSEA used by Brazilian recreational RT practitioners. For this, RT practitioners of both sexes (n=129, female=58 and male=71) answered a paper-based questionnaire. The questionnaire was specifically created for the studied population to assess different aspects of the DSEA used and sociodemographic variables.
Results: Seventy-seven percent of the participants (n=99) declared that they had already used DSEA. The majority (53%) searched the internet to obtain information about DSEA. Whey protein (66%) was the most used followed by branched chain amino acids (48%).
Conclusion: The use of DSEA, before coronavirus outbreak, was popular among RT practitioners; protein and amino acids were the most used DSEA. Most users used internet to obtain information about DSEA. The results suggest the need for appropriate attitude and guidance by health professionals who deal with this population, especially dietitians, nutritionists, and physical training professionals in order to promote best and security practices.
