Abstract：
Despite increasing awareness of plant-based diets for health and athletic performance, athletes are cautioned that careful dietary monitoring is necessary. Whether commonly consumed plant-based diets are nutritionally adequate for maximal muscular hypertrophy remains unknown. This modeling study assessed the nutrient composition of completely plant-based diets scaled to the caloric demands of maximal muscle mass and strength development in adult male bodybuilders. To model calorie requirements, anthropometric data from bodybuilders were input into the Tinsley resting metabolic rate prediction equation, and an appropriate physical activity factor and calorie surplus were applied. Dietary data from a large cohort following completely plant-based diets were then scaled to meet these needs. Modeled intakes for nutrients of interest were calculated as 1.8 g/kg/day of protein and 2.75 g/meal of leucine, which surpass mean requirements for maximal increases in muscle mass and strength and muscle protein synthesis, respectively. Daily levels for all micronutrients, except vitamin D, also exceeded requirements. Saturated fat levels were aligned with dietary guidelines, although sodium levels exceeded recommended limits. Consumption of larger portions of commonplace plant-based diets, scaled to meet the energy demands of maximal accrual of muscle mass and strength, satisfied protein and leucine requirements without the need for additional planning.
摘要：
尽管人们对植物性饮食对健康和运动表现的认识日益提高，运动员被警告说，仔细的饮食监测是必要的。通常食用的植物性饮食是否在营养上足以满足最大的肌肉肥大仍然未知。这项建模研究评估了完全基于植物的饮食的营养成分，以适应成年男性健美运动员最大肌肉质量和力量发展的热量需求。为了模拟卡路里需求，健美运动员的人体测量数据被输入到Tinsley静息代谢率预测方程中，并应用了适当的体力活动因子和热量过剩。然后将来自完全基于植物的饮食的大型队列的饮食数据进行缩放以满足这些需求。感兴趣的营养素的模型摄入量计算为1.8g/kg/天的蛋白质和2.75g/餐的亮氨酸，这意味着超过了肌肉质量和力量以及肌肉蛋白质合成的最大增加的要求，分别。所有微量营养素的每日水平，除了维生素D,也超出了要求。饱和脂肪水平与饮食指南一致，尽管钠含量超过了推荐限值。消耗大部分普通植物性饮食，缩放以满足肌肉质量和力量最大积累的能量需求，满足蛋白质和亮氨酸的需求，而无需额外的计划。
