有些研究人员已探讨了血糖在维持和延长强度运动时的重要性。通过对于运动时机体外源性葡萄糖的研究,已经发现有延长大强度运动的作用。最近对运动前30分钟口服葡萄糖的实验已有报导,机体在此种情况下进行运动时,血液中的胰岛素明显增加,同时就伴随着血糖浓度的下降。血糖浓度的水平是依照延长运动时,作为主要能源物质肌糖元的多少,以及其分同与合成的情况来决定的。如果肌糖元过早的耗尽,就会使工作能力有所下降。弗斯特,考斯梯鲁和冯克于1979年曾发现,当耐力性工作强度较大时,机体作功基本上是由葡萄糖供给能量的情况下,则
Some researchers have explored the importance of blood glucose in maintaining and prolonging intensity exercise. Through the study of exogenous glucose during exercise, it has been found that there is an effect of prolonging intensive exercise. Recent experiments with oral glucose 30 minutes prior to exercise have reported that when the body is exercising in such conditions, there is a marked increase in blood insulin, accompanied by a decrease in blood glucose levels. The level of blood glucose is determined by the amount of muscle glycogen as the main source of energy when extended exercise, as well as its sub-syn-tosynthesis. If muscle glycogen is depleted prematurely, it will reduce the ability to work. Forster, Kausitulu and Fengke had discovered in 1979 that when the work intensity of endurance was high, the work of the body was basically provided by the energy of glucose, then
