[Cardiac diastolic function in children and adolescents during prompt and long-term adaptation to physical exercise].
To study the natural changes in cardiac diastolic function in ontogenesis at various stages of exercise adaptation, 65 males aged 10-17 years who go in for various kinds of sports developing primarily physical fitness have been examined. Long-term adaptation to cyclic muscular activity has been shown to result in a reduction in cardiovascular lability, an optimization of inclusion of myocardial functional reserves, and an increase in efficiency of using cardiac cycle time in response to myocardial restorative processes. High stages of exercise adaptation formed an additional mechanism responsible for diastolic filling at the expense of an atrial systole (an atrial mechanism of diastolic regulation).
