A three day survey of food intake, training and sleep patterns was completed by 8 male and 12 female elite Canadian swimmers. Both groups were swimming similar training distances (ca. 9000m per day) and performed similar flexibility and strength training exercises. Males averaged 5 and females 4 meals per day (p < 0.05). In addition, the male swimmers are significantly more food from the meat, milk and grain food groups, taking in nearly twice as many calories as the female swimmers. The female swimmers were generally deficient in foods from the meat and milk group compared to recommended amounts. Twelve of the 20 athletes took additional food supplements. Both groups slept for similar periods of time each day (ca. 8h).
8名加拿大男子精英游泳运动员和12名加拿大女子精英游泳运动员完成了一项为期三天的饮食摄入、训练及睡眠模式调查。两组运动员的每日训练距离相近（约9000米），并进行相似的柔韧性和力量训练。男性运动员平均每天进食5餐，女性运动员平均每天进食4餐（p < 0.05）。此外，男性游泳运动员从肉类、奶类和谷物类食物组摄入的食物显著更多，摄入的卡路里几乎是女性游泳运动员的两倍。与推荐摄入量相比，女性游泳运动员通常缺乏肉类和奶类食物。20名运动员中有12人额外服用了膳食补充剂。两组运动员每天的睡眠时间相近（约8小时）。
