运动中补充不同饮料对女子马拉松运动员生理机能影响研究
目的 探究运动中补充不同饮料对女子马拉松运动员生理机能的影响。方法 对12名年龄为24~38岁女性马拉松运动员分别给予以下3种不同饮料补充研究, 测定3组运动员的最大摄氧量及运动前准备情况。将运动员主要分为CEPS(4%碳水化合物+2%蛋白质)、CES(6%碳水化合物), PLA(无碳水化合物+2%蛋白质), 随机交叉实验法进行3次21 km测试。结果 摄入CES后运动员跑步时间明显短于PLA, CEPS组运动员运动成绩则于其他2组差异无统计学意义(P>0.05); 与PLA组相比, CES组血糖水平高, CEPS组呼吸交换率高(P0.05)。结论 运动中补充6%碳水化合物饮料可能对女子马拉松运动员运动成绩的提升有促进作用。运动中补充6%碳水化合物饮料可能对女子马拉松运动员运动成绩的提升有促进作用。
Objective To analyze the effects of supplementing different beverages on the physiological functions of women marathon runners in sports. Methods Total of 12 female marathon runners aged 24 to 38 years old were given the following 3 different beverage supplement for study, the maximum oxygen uptake and pre-sport preparation of the three groups of athletes were measured, which were mainly divided into CEPS (4% carbohydrate + 2% protein) and CES (6% carbohydrate), PLA (no carbohydrate + 2% protein), and three 21 km tests were performed by random crossover experiment. Results After the intake of CES, the running time of athletes was significantly shorter than that of PLA, while the performance of athletes in CEPS group was not significantly different from that of the other 2 groups (P>0.05). Compared with the PLA group, the blood glucose level in the CES group was high. The respiratory exchange rate of CEPS group was higher than the PLA group (P0.05). Conclusion Supplementing 6% carbohydrates beverages in sports may promote the improvement of women marathon runners' performance.
