摘要
本文对16名在校中学生安静及定量运动负荷后心血管系统功能的变化情况进行了研究。结果发现:运动训练组安静时心率明显低于对照组,而动脉血压没有明显差异。运动后即刻运动训练组和对照组的心率和收缩压明显高于运动前安静状态,但运动训练组升高的幅度低于对照组。观察运动后的恢复情况,运动训练组的恢复明显快于对照组。结果表明,运动训练能有效地降低心率,减小运动负荷对心血管功能的影响。
The paper studies the differences of cardiovascular functions before and after sports training according to 16 middle school students as samples.It turns out： after sports training the experiment group＇s heart rates are obviously lower than the ones of the control group＇s,while artery blood pressure has no difference;heart rate and systolic pressure of the two groups＇ are much higher after doing sports than when keeping quiet,however,heart rates and systolic pressure of sports training group rise slower than the control group does.The observation finds the sports training group restores more quickly.The result shows that sports training can effectively slow down heart beating and reduce the burden brought to cardiovascular function by doing sports.
