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.
