摘要

橄榄球运动员按照传统膳食指南摄入大量动物蛋白,以增加肌肉质量和力量。这与国家膳食指南的建议不一致,国家膳食指南建议限制肉类消费以预防慢性疾病。完全以植物为基础的膳食能否满足橄榄球运动员的营养需求,目前还没有进行过研究。本研究将大量完全以植物为基础的膳食人群的营养数据按比例放大,并补充有限的蛋白质,以满足成年男性橄榄球运动员的热量需求,从而评估是否能达到蛋白质和亮氨酸对肌肉发育和运动表现的建议。卡路里需求量是根据采用双标水法的研究估算得出的,并将 "基督复临安息日会健康研究-2 "中的膳食数据按比例调整到这一水平。模型蛋白质水平为 1.68 克/千克/天,符合肌肉质量、力量和运动表现最大增长的建议。每日四餐的模型亮氨酸水平为 2.9 克/餐,超过了最大限度地刺激年轻男性肌肉蛋白质合成的阈值。这些结果表明,食用大量完全以植物为基础的膳食可以满足成年男性橄榄球运动员对蛋白质和亮氨酸的需求,从而最大限度地促进肌肉发育和提高运动成绩,同时也符合公众健康建议。

Protein and Leucine Requirements for Maximal Muscular Development and Athletic Performance Are Achieved with Completely Plant-Based Diets Modeled to Meet Energy Needs in Adult Male Rugby Players
Rugby athletes consume large amounts of animal protein in accordance with conventional dietary guidance to increase muscle mass and strength. This misaligns with national dietary guidelines, which suggest limiting meat consumption for chronic disease prevention. The ability of completely plant-based diets to satisfy the nutritional needs of rugby players has not been explored. This study scaled nutrient data from a large population consuming completely plant-based diets with limited supplemental protein to meet the calorie requirements of adult male rugby athletes to assess whether protein and leucine recommendations for muscular development and athletic performance would be achieved. Calorie requirements were estimated from research that employed the doubly labeled water method, and dietary data from the Adventist Health Study-2 were scaled to this level. The modeled protein level was 1.68 g/kg/day, which meets recommendations for maximal gains in muscle mass, strength, and athletic performance. The modeled leucine level was 2.9 g/meal for four daily meals, which exceeds the threshold proposed to maximally stimulate muscle protein synthesis in young men. These results indicate that consuming large portions of completely plant-based meals can satisfy protein and leucine requirements for maximal muscular development and athletic performance in adult male rugby athletes while aligning with public health recommendations.
