摘　　要：目的分析肌肉等长收缩持续时间与人体血压变化之间的关系。方法让16名健康男性在支撑器上做撑起动作,持续时间分别为5 s、10 s和15 s,间歇时间均为5 s,测试运动前后的左臂血压。结果不同持续时间的等长收缩运动后的收缩压与运动前的差异有显著性意义（P〈0.05）,舒张压差异无显著性意义,运动后的收缩压之间差异亦无显著性意义（P〉0.05）;运动前后收缩压的差值之间,持续5 s与持续10 s之间的差异无显著性意义（P〉0.05）;持续5 s与持续15 s之间及持续10 s与持续15 s之间的差异有显著性意义（P〈0.05）。结论持续肌肉等长收缩训练可使收缩压上升;缓冲反射对血压的调节作用持续时间在10-15 s之间。Objective To observe the relationship between duration time of isometric contraction and blood pressure. Methods The blood pressure of 16 healthy young males was recorded before and after 3 sessions of push-up exercise. All subjects did the push-up and hold there for 5 s （TS）, 10 s （T10） and 15 s （T15）, respectively. Results The systolic pressure increased no matter the isomet- ric contraction exercise lasts for 5 s, 10 s and 15 s （ P 〈20.05） and no significant difference was found in the systolic pressures after isometric contraction in group TS, group T10 and group T15 （ P 〉0.05）, and also no significant difference was found in the change of pulse systolic pressure between group T5 and group T10 （ P 〉0.05）, but there was a significant difference between both group T5 and group T15, group T10 and group T15 （ P d0. 05）. Conclusion The isometric contraction exercise can increase the systolic pressure and the effect of cushion reflex on adjusting blood pressure may last 10-15 s.
