摘　　要：本文观察了在实验室内严格控制负荷量,补液量及运动前饮食的条件下,运动员在热环境中运动2小时,补充康贝运动饮料的效果。结果表明:康贝饮料具有减轻运动后血液浓缩的程度;维持长时间运动的血糖水平;并可补充部分无机盐的丢失;对体温调节和维持体内酸碱平衡有一定作用;并可加速运动后的心率恢复。The aim of this study was to determine the effect of Kangbei(a hypotonic beverage developed in 1988) on athlete's physical work capacity in hot environment. A double-blind trial was carried out on 9 young male athletes who were ran-domly assigned to two exercise tests: with Kangbei or with placebo. The exercise lasted for 2 hours at a constant heart rate of150 bpm and a pedalling frequency of 60 rpm on a Monark bicycle ergometre. 250ml of Kangbei or placebo were drunk at15 min. before and 30,60,90 min. during the exercise. It was found that Kangbei had the effects of blunting the hemocon-centration after exercise, benefiting the maintenance of blood glucose during long-term exercise, complementing the loss ofsome inorganic salts, regulating body temperature and electrocardiogram, and speeding the recovery of heart rate follwingexercise. No untoward effect was observed in athletes after this test.
