In brief: The triathlon makes heavy demands on the body and especially on glycogen supply. This article describes the self-reported diet practices of 25 elite Australian male triathletes during training and racing. They consumed a mean of 4,095 kcal/day, 59.5% of which was carbohydrate, 13% protein, 27% fat, and 0.5% alcohol; glycogen and protein intakes met or surpassed recommended levels. Intakes of five vitamins and two minerals also exceeded recommendations, and iron status was satisfactory. The athletes ate carbohydrate mostly in complex form, snacking frequently to get enough for energy needs. Few subjects trained deliberately to build up a tolerance for consuming food and fluids during competition.
铁人三项运动对身体要求很高，尤其是对糖原供应的要求。本文介绍了 25 名澳大利亚男性精英铁人三项运动员在训练和比赛期间的自我报告饮食实践。他们平均每天摄入 4095 千卡，其中 59.5%为碳水化合物，13%为蛋白质，27%为脂肪，0.5%为酒精；糖原和蛋白质的摄入量达到或超过了推荐水平。五种维生素和两种矿物质的摄入量也超过了推荐量，铁的状况令人满意。运动员主要以复杂形式摄入碳水化合物，经常吃零食以满足能量需求。很少有运动员有针对性地训练以提高在比赛中进食和饮水的耐受性。
