[The effect of weight loss caused by tissue dehydration on changes in carbohydrate metabolism under physical load].
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.
