Athletes should match their energy intake with expenditure in order to maintain lean body mass. It is also important to consume adequate amounts of antioxidant vitamins and minerals to maintain health.
To assess the dietary habits of six nationally ranked Australian swimmers physical training load and dietary intake (24 h food recall) and were recorded on a daily basis during a 4 day intensive physical training period.
The results showed no significant difference between energy intake and expenditure (P=0.58) or the amount of carbohydrate consumed (P=0.14) compared to the Australian recommended daily intake (RDI). Athletes reported a significantly greater intake of vitamin A (P<0.01), vitamin C (P<0.01), vitamin E (P<0.01) and protein (P<0.01) than the RDI.
It was concluded that these elite swimmers have an adequate dietary intake to allow for optimal physical training and performance.
运动员应使能量摄入与消耗相匹配,以维持瘦体重。摄入足够量的抗氧化维生素和矿物质对保持健康也很重要。
为评估六名澳大利亚国家排名游泳运动员的饮食习惯,在为期4天的强化体能训练期间,每天记录其体能训练负荷和饮食摄入量(24小时食物召回)。
与澳大利亚推荐每日摄入量(RDI)相比,能量摄入与消耗(P = 0.58)或碳水化合物摄入量(P = 0.14)之间无显著差异。运动员报告的维生素A(P < 0.01)、维生素C(P < 0.01)、维生素E(P < 0.01)和蛋白质(P < 0.01)摄入量显著高于RDI。
得出的结论是,这些精英游泳运动员有足够的饮食摄入量,以实现最佳体能训练和表现。
