Suboptimal energy and carbohydrate intake in male CrossFit® practitioners: Adequate protein but imbalanced distribution
Abstract
Objective: This study aims to evaluate the dietary intake of male CrossFit® practitioners, focusing on energy consumption, macronutrient distribution, and pre- and post-training nutrient intake. Materials and Methods: The study was conducted with 31 male CrossFit® practitioners. Participants provided four 24-hour dietary recalls over two weeks. Energy and nutrient intake were analyzed, and adequacy was evaluated against established nutritional recommendations. Protein and carbohydrate intake were compared pre- and post-workout, and the percentage of animal protein intake was assessed. Results: The average energy intake was 29.7 ±7.6 kcal/kg/day, below the recommended 30-50 kcal/kg/day. Carbohydrate intake averaged 3.4 ±1.0 g/kg/day, also below the recommended 5-12 g/kg/day, with only 9.67% meeting the recommendations. Protein intake was within the recommended range at 1.8 ±0.4 g/kg/day. Post-workout meals had significantly higher protein (41.4 ±15.9 g) and carbohydrate (66.2 26.7 g) intake compared to pre-workout meals (19.7 ±13.2 g and 50.6 ±25.2 g, respectively). The diet was predominantly animal-based, with animal protein comprising 77.7% of total protein intake. Conclusion: The study highlights suboptimal energy and carbohydrate intake among male CrossFit® practitioners, with adequate protein intake but an imbalance in protein distribution across meals.
