【摘要】 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。更多还原

【Abstract】 During.the training period requiring a low amount of protein for winter sports athletes, a study was made by means of the nitrogen balance method are 139g/man/day(speed skating), 95g/woman/day (speed skating), 110g/man/day (skiing), 64g/woman/day (skiing) and at the high-dose protein training they are 165g/man/day (speed skating), 106g/woman/day (speed skating). The athletes’ responses to higher protein intake are: easily to feel thirsty, to be sick of taking meat, fish and chicken and to want vegetables and fruits. This suggests that it is necessary to further research the nutrition requirements of winter sports athletes, so as to promote this kind of sports in our country.更多还原
