Keyword:  蹲起试验VO2max心功指数效度;
Abstract: 为探索一种简便有效的评价人体心血管系统功能的定量运动负荷方法,采用3种不同负荷的蹲起试验方法对30名普通大学生的累积、即刻心功指数与他们的VO2max进行相关性研究,以相关系数的大小来判别各自的效度.发现60 s 60次蹲起测得的心功指数与VO2max的相关系数最高,45 s 45次蹲起的心功指数次之,30 s 30次最低,而3种不同负荷方法各自的即刻心功指数与VO2max的相关性均高于累积心功指数.认为60 s 60次蹲起试验测试心功能的方法(即刻心功指数)简单实用、评价效度高、易于实施与控制,有望成为简便有效的评价人体心血管系统功能的定量运动负荷方法.
