摘　　要：比较了口服补液盐(Oral Rehydration Solutions,ORS)与运动饮料(Sports Drink Solutions,SDS)在高温运动过程中对试验大鼠新陈代谢的影响。试验结果显示:两组试验中的血红蛋白水平显著升高,出汗率和脱水率无显著差异,血浆体积的变化显著,血葡萄糖含量显著高于对照组。完成运动后,SDS中的脂肪氧化低于ORS。研究结果表明,在高温运动过程中补充水分时,ORS和SDS的体液保留能力无显著差异,表明在炎热环境中运动时摄入的液体量可能比饮料的内容物更为重要。运动饮料能更好地维持血糖水平,在有限的CHO摄入量和较长的高强度工作时间的情况下,如在持续运动或户外作业中,运动饮料摄入为更优的选择。The effects of oral rehydration solutions(ORS)and sports drink solutions(SDS)on the hydration and metabolism of experimental rats during high temperature exercise were compared.The results showed that the hemoglobin level of the two groups increased significantly,and the sweating rate and dehydration rate had no significant difference.In the two treated groups,the change of plasma volume was significant difference,and the blood glucose content was significantly higher than that of the control group.After exercise,the fat oxidation in SDS was lower than that in ors.However,no difference was found between groups of ORS and SDS in the capacity of body fluid retention when water was replenished during the high temperature exercise.This indicated that the amount of fluid ingested during exercise in hot environment might be more important than the content of beverage.Sports drinks could maintain better blood glucose level.In the case of limited CHO intake during the long-time and high-intensity work,such as in continuous exercise or outdoor work,sports drink intake was a better choice.The results of the study will provide reasonable suggestions for the safety work and physical performance of athletes,military personnel and outdoor high-intensity workers.
