The Impact of Durable and Regular Training in Handto- hand Fighting Section on Aggregative Platelet Activity of Persons at the First Mature Age

摘要

Platelets, as one of the main elements of a body’s homeostasis, support it on the whole and especially blood system. Through the modulation of their activity in response to different impacts they can influence the microcirculation and the level of tissue metabolism. The aim of our research is to determine platelet aggregative activity of healthy people of the first mature age which have long regular physical training in the section of hand-to-hand fighting. We took 112 healthy people of the first mature age, who had trained since childhood in hand-to-hand fighting section, into our experimental group. The control group was composed of 97 healthy people of the first mature age who had avoided any exercises during their lifetime. We applied biochemical, hematological and statistical methods of investigation. Physically trained people during the first mature age had stable low lipids’ peroxidation in platelets. This experimental group also had stable low platelet aggregation. The constancy of platelet aggregative response to strong and weak inductors of hand-to-hand fighters was provided by stable low activity of platelet receptors and intraplatelet mechanisms of their aggregation. Basing on the mentioned information, we could state that regular physical training in hand-to-hand fighting section since childhood provided the fighters of the first mature age with stable low platelet activity. It also helped to create better conditions for microcirculation and hemostasis. In people, who had avoided exercises, there was increase of platelet aggregation at the first mature age though they could have no complaints on their health.
