本文提出了人工增加血液中标准重碳酸盐含量,最大限度地提高机体血液是的碱储备量,并以此来缓冲机体由于剧烈运动而突然增多的,又无法通过其它途径迅速排出的酸性代谢产物,从而达到延缓疲劳到来,提高机体乳酸能系统供能能力的设想;长通过对CSUF体育系27名从事中短距离跑的运动员做了力竭运动前服用NaHCO_3药片的实验,其结果证明它确是一项提高运动成绩、延缓疲劳到来的好办法. This paper proposes to manually increase the standard bicarbonate content in blood to maximize the body’s reserve of blood is the base, and thus to buffer the sudden increase in body due to strenuous exercise, and can not be rapidly discharged by other means of acidic metabolism So as to delay the onset of fatigue and improve the ability of the body to supply energy to the lactate energy system. Through the experiment on 27 NaHCO 3 -free tablets taken by CSUF sports department athletes engaged in medium and short distance running, the results show that it It is a good way to improve athletic performance and delay the onset of fatigue.
