(heart failure).

The influence of shaping lessons on the state of the body systems

KNOWLEDGE BASE

One of the most important effects of training – the slowing of the heart rate at rest (bradycardia) as a manifestation of the economization of cardiac activity and a lower need for hospitalization of oxygen. The increase in the duration of a phase of diastole (relaxation) provides more cots and best supply the heart muscle with oxygen. In patients with bradycardia cases of CHD detected much less frequently than in people with frequent pulse. It is believed that the increase in resting heart rate by 15 beats/min increases the risk of sudden death from heart attack by 70% – the same pattern is observed when muscle activity. When the standard load

on a Bicycle Ergometer in the trained men, the volume of coronary blood flow is almost 2 times less than in untrained (140 vs. 260 ml/min per 100 g of myocardial tissue), respectively 2 times and less need for hospitalization of oxygen (20 to 40 ml/min per 100 g tissue). Continue reading
