摘　　要：以Bruce运动方案 ,测定了 5 6名体院与普通大学学生运动中潮气量 (Vt)、通气量 (VE)、呼吸频率 (RR)及潮气末CO2 分压 (PetCO2 )等气体代谢指标 ,结果显示前三项指标随负荷增加呈非线性增长特征。结果还表明 ,AT值前Vt上升幅度大于RR ,AT值后VE进一步增大 ,则更多依赖于RR的增加。运动极限时PetCO2 升至最高 。With Bruce sport method, metabolism indices such as Vt, VE, RR and PetCo2 of both common university students and sports institute university students in sport exercises have been measured. The first three indices will non-linearly increase with load. These data also show that before AT, the increase rate of Vt is larger than that of RR, and after AT, Ve will further increase but it is mainly respect with the increase of RR. At the limit of exercising PetCO2 reaches its climax. There is no difference between the two groups of experimenters.
