| 摘 要： | 目的：通过测量健身快走运动中能量消耗特征揭示其变化情况,为大学生健身效果评价提供依据。方法：8名普通男大学生以6.5km/h匀速进行60min快走运动,采用气体代谢法测定并推算机体能量消耗状况。结果：1）25min时糖和脂肪二者供能百分比分别为50.7%、49.3%。2）脂肪供能量45min后快速增加,60min时值最高,糖供能量逐渐下降,结束为（1.47±0.57）Kcal/min·kg。3）糖氧化量前10min缓慢增长后减少,结束值为（0.29±0.12）g/min·kg,脂肪氧化量30min后快速提高,结束值为（0.87±0.06）g/min·kg,40min-45min出现均衡,为0.79g/min·kg。结论：1）25min时糖脂肪供能百分比形成交叉。2）供能百分比、供能量、氧化量随时间延长脂肪均大于糖。3）从能量代谢和底物代谢角度看,6.5km/h速度进行60min快走属中等强度,从长时间健身走供能关系来说对大学生健身有积极作用。
