Factors associated with the use of dietary supplements by physical exercise practitioners treated at a health unit

Abstract

The objective was to evaluate the factors associated with the use of dietary supplements by physical exercise practitioners treated at a nutrition outpatient clinic. The research was carried out in Viçosa, Minas Gerais, with 71 individuals, over the age of 18, who had been exercising for at least three months. During nutritional care, information was obtained about physical exercise, use of supplements and general habits. Weight and height were measured to calculate body mass index (BMI) and seven skinfolds to estimate body fat and fat-free mass. Among those interviewed, 51.1% were female and half (50.7%) practiced some strength and resistance exercise. The majority reported dietary supplements consuming (77.5%), most of them on their own initiative (65.7%). Men were also those who consumed the most supplements (91.2%). The most used supplements were whey protein (53.5%) and creatine (52.1%). A greater use of supplements was observed in individuals who had a longer duration of moderate to vigorous physical exercise (≥ 540 min/week). A lower percentage of body fat was observed in those who used supplements, specifically whey protein, compared to those who did not use them. It is concluded that there is a high prevalence of the consumption of dietary supplements among those who exercise at the health unit. However, the use of this resource is still not carried out correctly, and is often used without prescription and monitoring by a professional.
