Use of nutritional ergogenic resources in crossfit® practitioners
Abstract
CrossFit® is a core strength and fitness program designed to provide the most adaptive response possible. It has been developed to enhance an individual's competence in all physical tasks, becoming increasingly popular as a mode of exercise as well as a competitive sport. The present study aims to evaluate the use of ergogenic nutritional resources in CrossFit® practitioners. The sample consisted of 113 CrossFit® practitioners residing in the state of São Paulo who answered a structured form of 12 questions (Google Form). In total, 75% (n=85) reported the use of some REN, being the prevalent use in males (56%). Twenty-six types of REN were reported, with three being the most used: whey protein, BCAA and creatine. In total, 63% of REN users reported receiving the recommendation through health professionals, of which 87% came from nutritionists. Additionally, 14% of the participants stated that they use ergogenic pharmacological resources. The prevalence of REN use by CrossFit® practitioners is high, driven by reasons that still lack scientific evidence. The use of performance enhancing substances is a personal choice, however, it is important that the nutritionist keeps up-to-date to work with athletes to effectively evaluate, recommend, educate, and monitor those contemplating the use of REN.
