The Intensity of Physical Activity and Heart Contractile Function of Mass Sports Categories Athletes
In the process of studying the effect of intensity of physical activity on the reactivity of the heart contractile function of mass sports categories athletes and, in particular, the peculiarities of electrical and mechanical processes of the myocardium during the heart contractile function of judoists 16-20 years, it is established that with a progressively increasing competitiveness load, more trained athletes have quite a complete synchronization of mechanical and electrical processes of the myocardium. Such vegetative synchronization adequately changes as the heart rate increases, as well as the shortening in time of the complete cardiac cycle. The authors experimentally showed that when planning training occupations for judoists 16-20 years of mass sports categories needs to be considered that duration of myocardium contractile function depends on the optimality of the ratio of metabolic and contractile processes in the athlete’s hard-working heart and the level of functional fitness of the heart.
