【摘要】 本文采用称重法和Douglas-Haldame气体代谢法对划船运动员的营养状况和能量消耗进行了调查。结果显示男运动员除碳水化合物和维生素B₁低于标准外,热量和其他营养素均达到标准,而女运动员除脂肪和维生素C外,热量和其他营养素均不足。热能和营养素的三餐分配和来源亦不够合理,脂肪占总热能比例过高。能量代谢测定提示男运动员可以满足对热能的需要,但女运动员热能供给不能补偿能量消耗。因此,对女运动员应提高热能和各种营养素的供给量,同时应考虑改变三餐热能分配和营养素来源的不合理状况。更多还原

【Abstract】 Nutritional studies and energy consumption were made by methods of heavy weight and atmosphere metabolism on rowboat athletes. Results showed that maled athletes who take the energy and other nutrients were enough for their exercise except carbohydrates and vitamine B1, females athletes’ energy and other nutrients were lower than that of standard except fat and vitamine C. Division and resources in three kinds of energy and nutrients were unreasonable as well. Determination of endrgy consumption presents that males athletes can be sa- tisfied with their emands in addition to females athelets. So they must improve their providing vol- ume in energy and different nutrients. On the oth- er hand, energy divition in 3 meals and nutrients resources should be changed because it is unresea- sonable.更多还原
