目的:研究一种促进运动疲劳恢复的饮料对运动员的抗疲劳作用。方法:17名体校女子运动员分成两组,其中实验组每天服用该饮料,对照组则服用安慰剂。连续服用2周,服用期间实验组与对照组训练量保持相同。服用前后测定血红蛋白(HB)、血尿素氮(BUN)、血清肌酸激酶(CK)等指标。结果表明:该饮料能明显提高运动员体内血红蛋白含量(p<0.05),减少尿素氮产生量(p<0.05),减轻受试者运动后主观疲劳感觉(p<0.05),提高运动成绩(p<0.05)。结论:该饮料具有良好的抗疲劳作用。
OBJECTIVE: To study the anti-fatigue effect of a beverage that promotes recovery from exercise fatigue on athletes. Methods: Seventeen female college athletes were divided into two groups, of which the experimental group took the beverage daily and the control group took the placebo. Taking for 2 weeks continuously, the training amount of experimental group and control group remained the same during taking. Before and after taking the determination of hemoglobin (HB), blood urea nitrogen (BUN), serum creatine kinase (CK) and other indicators. The results showed that the beverage significantly improved hemoglobin content (p <0.05), reduced urea nitrogen production (p <0.05), reduced the subjective fatigue feeling after exercise (p <0.05), and improved the performance of sportsmen (p < 0.05). Conclusion: The beverage has a good anti-fatigue effect.
