为了解与制定冰、雪运动员的营养与有效膳食,通过氮代谢实验证明其氮代谢均为正氮平衡。低剂量训练期冰及雪上男、女运动员的蛋白质摄入量依次分别为181g/日/人,101g/日/人,123g/日/人及100g/日/人,估测蛋白质需要量为139g/日/人,95g/日/人,111g/日/人及64g/日/人,大剂量训练期冰上男、女运动员蛋白质摄入量为20g/日/人及119g/日/人,而估测蛋白质需要量为165g/日/人及106g/日/人。 In order to understand and formulate the nutrition and effective diet of ice and snow athletes, the nitrogen metabolism is confirmed by the nitrogen metabolism experiment. The intake of protein in ice and snow male and female athletes during the low-dose training sessions were 181 g / day / person, 101 g / day / person, 123 g / day / person and 100 g / day / person, respectively. The estimated protein requirement was 139 g Day diet, the daily intake of protein was 20g / day / 119g / day and 119g / day / person on the ice, The estimated protein requirements for 165g / day / person and 106g / day / person.
