| 摘 要： | 利用MCA-3C心脏功能信息检测仪,探讨运动训练对心脏的张力-收缩速度及左心室功能的影响.以普通专业女大学生(对照组,n=9)、体育教育专业女大学生(体教组,n=9)和女子曲棍球队运动员(女曲组,n=9)为研究对象,测量其安静状态及40W,80W和120W负荷蹬车3min(转速为60r/min)结束即刻、120W恢复期第5min和第10min的心缩间期(STI)各项指标.结果表明,运动训练可改善训练者安静时心脏功能,通过降低HR,延长LVET,缩短ICT,延长MST来实现;运动训练可改善训练者运动时心脏功能,通过降低运动时HR上升幅度,延长LVET,缩短小强度及中等强度运动时ICT,维持大强度运动时ICT不再继续缩短来实现;运动训练对加速训练者运动后HR恢复,维持运动后恢复期MST及EML稳定具有良好的作用.
