用“高效强力饮”在八一田径队和游泳队进行了双盲随机配对分组应用研究。结果表明,实验组的心血管功能较对照组明显提高,表现在每搏量、射血效率增加,脉搏减慢,总外周阻力降低,心功能指数增高,认为是增强了心脏收缩力取得的。另外,实验组的血红蛋白水平亦有明显升高。 A double-blind randomized pairing application study was conducted on the Bayi track team and the swimming team using “high-efficiency strong drink”. The results showed that the cardiovascular function of the experimental group was significantly higher than that of the control group, which manifested in stroke volume, increased ejection efficiency, slower pulse, decreased total peripheral resistance, and increased cardiac function index, which was considered to have enhanced cardiac contractility. In addition, the hemoglobin level in the experimental group also increased significantly.
