参赛运动员30名,以配对法分为实验组和对照组各15人,实验组服“高效强力饮”4用(包括运动会期间)。“对照组不服用。结果表明该药能改善运动员的机能状态,创出比对照组明显好的成绩,头发中微量元素含量自身前后时比,Cr、Ni水平明显升高,时照组却下降,Fe值两组均有所增加,血清Zn、Cr含量参赛后均有不同程度下降;血清Mn值实验组有上升趋势,而对照组稍下降。
Thirty participating athletes were divided into experimental group and control group by 15 pairs. The experimental group took “high-efficiency and strength-drinking” for four times (including during the sports meeting). "The control group did not take it. The results showed that the drug can improve the athletes’ functional status and create significantly better results than the control group. The content of trace elements in the hair itself was significantly increased before and after, and the levels of Cr and Ni were significantly higher, but the time control group was decreased. Both Fe and Fe values increased in the two groups. Serum Zn and Cr contents all decreased after the competition. Serum Mn values in the experimental group increased, while those in the control group decreased slightly.
