【 摘 要 】

Background: Nutritional composition of the athletes’ diet in relation to their training routineand body composition is critical in maintaining high performance levels during competitions.Objective: This study aimed to investigate the body composition and nutrient intake of CrossFit®athletes. Methods: Twenty-five Brazilian CrossFit® athletes (18–50 years old) were evaluatedin this study. Height, weight, and body mass index (BMI) were measured. A portable ultrasoundwas used to assess body composition. Resting energy expenditure was evaluated by indirectcalorimetry. To describe the nutrient intake, 175 diets prepared by nutritionists were analyzed(mean diets per athlete = 7). To verify adherence, three non-consecutive self-reported 24-hourdietary recall surveys per diet were analyzed, totaling 525 days of food consumption record, andthe mean of these 24-hour dietary recalls was used in this study. Results: The mean age was32.0 ± 8.9 years, with no differences between men and women (P=0.208). The mean BMI was26.4 ± 2.6 kg/m2. Energy intake was 2,904.0 ± 697.3 kcal/day. Protein and carbohydrate intakewas 2.3 ± 0.4 and 4.5 ± 2.0 g/kg/day, respectively. Regarding carbohydrate consumption, 44% ofCrossFit® athletes consumed less than the recommended amount (5–12 g/kg/day). In addition,most athletes (>50%) had insufficient intake of potassium, selenium, calcium, and vitamins A, D,B9, and B12. Conclusion: It can be concluded that CrossFit® athletes presented an insufficientintake of some vitamins, minerals, and carbohydrates.
