【摘要】 采用实验法,对皮划艇运动员不同负荷状态下左心功能的研究。结果发现,1 )运动员的心率出现安静时机能节省化、定量负荷反应低、恢复快等特点。运动员组心率恢复速度快于对照组;2 )无论处于何种状态,运动员组的左室射血时间均显著长于对照组,提示,其每搏输出量始终大于对照组,可视作训练程度高、训练效果佳的重要特征等更多还原

【Abstract】 Through using the method of experiment,this paper studied life ventricular function at different training load of kayak canoeist.The result shows that heart rate of canoeist displays the character of functional economy at rest,low reaction at fixed load and rapid recovery.The recovery of trained group is faster than control group.At any condition,the time of ventricular ejection for trained group is significantly longer than control group.It suggests that stroke output is also larger than control group.These two parameters can be regarded as the important character of high level of training and good training effect.更多还原
