Abstract

Background. The trainee’s organism is often solicited to its maximum capacity, which means that many homeostatic indicators are totally disturbed for a period of time.
Aims. Investigating the electrolyte’s circuit through the testing of specific biochemical parameters can point out as well as the immediate cellular dynamics, as well as the homeostatic modifications on a long term.
Methods. We have applied the longitudinal experiment, observing the changes in different variables at different moments of the effort. In order to do this, we considered the independent variable – the specific effort – athletics and cycle on a distance of 30 km, and the dependent variables - the blood level of sodium and potassium ions.
Results. Determining serum ions before and after the effort has revealed significant quantity changes, caused by the decrease of permeability of the cellular membranes and the acceleration of protean catabolism, specific to an aerobic effort.
Conclusions. The orientation of the electrolytic oscillation curves belong to endurance effort and are unique for the sportsman’s organism, representing a safe way to assure the mineral rebalancing of recovering.
