少年运动员心功能对动静力负荷的适应

The Adaptation of Cardiac Function to Dynamic and Static Loads in Juvenile Athletes

本文通过对少年耐力和力量运动员心功能在动力和静力负荷后各项指标变化的测定,讨论了STI、SV、SW、mW等有关指标的适应,进一步讨论运动员心脏心肌增厚的成因,并对运用运动员心脏作功指标及心肌耗氧指标探讨运动员心脏成因的可行性提供了实验依据。

The adaptation of STI, SV, SW, mW, and other cardiac functional indexes to dynamic and static loads in juvenile athletes of endurance and strength sports was measured and discussed in this paper. Discussed was also the etiology of myocardium hypertrophy in athletes. Finally some laboratory data were provided for the investigation of the causes of athletic heart with the help of the evaluating indexes of athletic heart work and oxygen consumption in myocardium.
