Análise nutricional e impacto do consumo calórico em praticantes de crossfit: uma revisão da literatura

Abstract

CrossFit is a high-intensity physical training modality that demands specific energy requirements, making nutrition an essential factor for athletic performance and practitioners' health. This study aims to analyze the dietary practices of CrossFit practitioners, emphasizing the adequacy and inadequacy of macronutrient consumption and caloric intake, as well as evaluating how these choices impact athletic performance and health. The research was based on a bibliographic review of studies published between 2014 and 2024 on the nutritional needs of this group, focusing on the consumption of carbohydrates, proteins, lipids, and calories and their effects on physical performance. The methodology consisted of an integrative literature review, with searches conducted on platforms such as PubMed, Capes, and Google Scholar. The results indicated significant deficiencies in carbohydrate consumption, impairing muscle glycogen replenishment and performance in high-intensity activities. Additionally, there was a tendency toward excessive protein and lipid intake, particularly influenced by restrictive diets, which may compromise muscle recovery and metabolic health. Caloric intake was also found to be below recommended levels, suggesting a practice of underfeeding with potential negative effects on hormonal and immune functions. The findings highlight that many CrossFit practitioners do not follow a balanced diet, which can impact both performance and long-term health.
