摘要
本文通过对19－22岁的30名受试者进行呼吸性窦性心律失常的检测，探讨心率变异性能否成为运动员选材的客观指标。结果表明，在低频呼吸状态下，体能较好的学生比对照组RSA明显增强。与测试心率等常规指标相比，RSA的变化更能反映心脏、血管和呼吸机能的状态。
According to the testing results of the abnormal respiratory sinus heart rates of 3O testers aged from 19 to 22, the paper domonstrated that, in the condition of lower respiratory frequence, the RSA of students with better physical abilities increased more significantly than that of the contrast group. Compared to regular indice, the RSA changs can betterly reflects the functional conditions of the heart, vessels and resportory system.
