【摘要】 以普通男性大学生和体育运动学校男性学生为研究对象 ,以 V O2 max为心血管功能指标 ,以 12 min跑为有氧耐力指标 ,用所测得的 3种不同高度的台阶试验后即刻心率、恢复期 0～2 10 s中不同时段心率恢复速度 (斜率 )与 V O2 max、12 min跑和台阶试验指数进行相关性研究。结果显示 :心率恢复速度 (斜率 )与 12 m in跑、台阶指数相关程度较高 ;即刻心率与 V O2 m ax、12min跑、台阶试验指数均有高度相关 (P<0 .0 1)。提示 :心率下降斜率 ,特别是中、高台阶试验后早期下降斜率能很好地反映有氧耐力 ;台阶试验后心率反应程度能较好地反映心血管功能和有氧耐力 ;可以用运动后即刻心率、早期心率恢复速度取代或改良原来的计算方法进行台阶指数计算 ,提高测试效率和准确性更多还原

【Abstract】 Taking male college students and sports school stude nts as research subject,O 2max,12min Running are indexes separately r eflecting cardiovascular capa city and aerobic endurance,instant heart rate and heart rate recovery rate in 0~ 210s recovery time from different height are chosen to do related research with O 2max,12min Running and step test index.The result shows that the ra t e of heart rate recovery has significant correlation with 12min running and step test index,instant heart rate has correlation with O 2max,12min Runn i ng and step test index.It suggests that slope of heart rate decline can effectiv ely reflect aerobic endurance especially the latter period at middle and high step test.The degree of heart rate response after step test is an important index reflecting cardiovascular capacity and aerobic endurance in order to improve the efficiency and veracity of calculation.Instant heart rate after exercise and early period rate of heart rate recovery can be used to calculate step test index.更多还原
