Moderate dehydration of rats led to a certain reduction of glycogen content in the liver and muscles. The analogous changes were observed when the animals were subjected to physical load. The previous dehydration also causes a delay in glycogen l-vel restoration in tissue after work is over. Under usual conditions physical load which wrestlers underwent on a veloergograph caused a certain increase in the concentration of lactic and pyruvic acids in blood. Against a background of previous dehydration physical load of the same intensity caused a more considerable change in these values. Consequently, even moderate dehydration of an organism practised by some sportsmen leads to considerable change in certain values of carbohydrate metabolism. It may be one of the reasons of a negative influence produced by weight loss on working capacity.
大鼠的中度脱水导致肝脏和肌肉中糖原含量有所降低。当动物承受体力负荷时，也观察到了类似的变化。先前的脱水还会导致工作结束后组织中糖原水平恢复延迟。在正常情况下，摔跤运动员在功率计上承受的体力负荷会使血液中乳酸和丙酮酸的浓度有所增加。在先前脱水的背景下，相同强度的体力负荷会使这些值发生更显著的变化。因此，即使是一些运动员所经历的机体中度脱水也会导致碳水化合物代谢的某些值发生显著变化。这可能是体重减轻对工作能力产生负面影响的原因之一。
