摘要
目的 观察人力短臂离心机训练后心血管功能的改变 ,探讨人力短臂离心机的训练效果。 方法 9名健康男性青年利用人力短臂离心机进行训练 ,转速为 30～ 34r min ,持续时间为5min ,1次 d ,连续训练 7d。测量心血管功能的变化。 结果 人力短臂离心机训练 3d后 ,心率显著降低 (P <0 .0 5 ) ,左室射血时间 (LVET)显著延长 (P <0 .0 1) ;训练 7d后 ,心率进一步降低 (P <0 .0 1) ,左室射血时间显著延长 (P <0 .0 5 ) ,每搏量显著增加 (P <0 .0 5 )。 结论 人力短臂离心机连续训练 7d后可明显改善心脏泵血功能。
Objective To explore the change of cardiovascular function after training with self powered short arm human centrifuge. Methods Nine healthy male volunteers underwent self powered short arm human centrifuge training 5 min per day with rotary speed of 30～34 r/min for 7 days. Cardiovascular function was measured before and after training. Results Heart rate (HR) decreased significantly while left ventricular ejection time (LVET) increased significantly after 3 d training, and the changes of HR and LVET were more obvious after 7 d training. Stroke volume increased significantly only after 7 days training. Conclusions It suggests that cardiac pumping function could be improved after 7 days training with self powered short arm human centrifuge. The self powered short arm human centrifuge may be used as a countermeasure to the effect of microgravity.
