[The effect of physical training loads on the body function of sailors on a long cruise]

The article studies the influence of physical exercises at sports simulators upon the state of some bioenergetic systems of seaman's organism in the conditions of a 4-month cruise. The article discloses the dynamics of maximum oxygen consumption, pH value, the quantity of buffered bases and standard bicarbonate in blood; activity of lactic dehydrogenase and its isoenzymes in serum; activity of lactic dehydrogenase, alpha-glycerophosphate dehydrogenase, etc. in lymphocytes of peripheral blood. The authors discuss the reasons of changes that take place in aerobic and anaerobic processes of cells and the whole organism.
