摘　　要：目的:探讨立姿振动力量训练和传统力量训练后,心脏泵血的变化。方法:32名男性志愿者,在立姿振动或传统训练条件下,负重深蹲训练12周,测试实验前、后安静时心脏泵血能力。结果:实验组左室射血前期和收缩期延长,心输出量、心指数和每搏量、搏功和每分功降低,与对照组的差异显著(P 0.05)。结论:低频高幅立姿振动力量训练减弱心脏泵血能力。Objective: To investigate the changes of cardiac pumping function in young men after the standing vibration strength training and traditional strength training. Methods: Squat training was carried out in 32 male volunteers in the condition of traditional or standing vibration for 12 weeks, the heart pumping ability in rest is tested before and after experiment. Results: Ejection pre-period and systolic period of experimental group was prolonged;cardiac output, cardiac index, stroke volume, stroke work and work per minute were lowered;the difference was significant compared with the control group (P 0.05). Conclusion: Standing vibration in low-frequency high amplitude strength training weakened pumping ability of the heart.
