Abstract
Our studies have shown that physical activity (bicycle ergometry) alters the biochemical status of male volunteers. We observed a significant decrease of glucose level and an increase in concentration of magnesium, phosphorus and especially of lactic acid in capillary blood after 5 min of bicycle ergometry start. Creatine phosphokinase activity and the concentration of triglycerides did not differ significantly from the original values. The tendency of changes in the examined parameters was the same in the supine and in the sitting positions. Therefore, biochemical investigations may complement essentially the physiological and neurophysiological tests of human adaptability to physical loads. The method of dry chemistry described in this study can be effectively used in a space flight as the rapid method for evaluation of biochemical parameters of the body.
