Introduction: Physiologically, platelets are an important component of homeostasis of the whole body and blood system. However, not everything is clear with platelet activity of young healthy persons who have systematic exercises, particularly masters of sportsâ€™ candidate. Its in vitro and in vivo should be studied further.
Aim: The aims of this investigation are to find out the abnormalities of thrombocyte activity of master of sportsâ€™ candidate in athletics of young age and compare them with thrombocyte level of young people who avoided exercises during their lifetime. Â Through modulation of their activity, they increase capillaries' perfusion and thereby metabolism in tissues.
Materials and methods: In our investigation group we took 125 candidates into masters of sports in athletics of preadult age regularly exercising and participating in competitions of different levels. Control group was consisted of 141 healthy youths having avoided exercises during their lifetime. Biochemical, hematological and statistical methods are applied.
Results: Athlete were found to have stable normal functional platelet activity. For subjects between 18 and 22 years, their platelets aggregation was on low level and had no reliable variations related to their stable low sensitivity to inductors. Decreased platelet activity causes conservation in athletes' blood of some quantity of circulating thrombocyte aggregates. It makes positive impact on microcirculation in organs of athlete having regular athletic exercises. Avoidance of exercise in young age promotes gradual rise of thrombocyte activity. Masters of sportsâ€™ in athletics candidate who had intensive muscle activities are characterized by persistence of stable low platelet activity. It provides low quantity of active platelets and their circulating aggregates in blood. Those young persons, who avoided exercises, are noted to have elevated platelet activity with a tendency increased aggregate formation.
Conclusion: Masters of sports in athleticsâ€™ candidate doing intensive muscle activity are characterized by preservation of stable not high platelet activity caused by low content of active platelets and their circulating aggregates. Avoiding exercises in young people are noted to have caused the increase of platelet activity with a tendency to cause platelet aggregation.
