两种训练方式对男大学生心泵血功能的影响

Effects of two training methods on function of the heart as a pump in male university student

为了探讨同属有氧训练的短期耐力训练和力量性耐力训练对男大学生心泵血功能的影响 ,分别在训练前、训练 6周和 8周后测试了 2 0名男大学生的SV和CO。结果发现 :耐力训练 6周后SV和CO有显著性提高 ,而力量性耐力训练 8周后SV和CO才有显著性提高 ,这提示短期耐力、力量性耐力训练都能增强男大学生心泵血功能 ,但存在一个不同的训练时间阈。

To investigate effects of short term endurance and strength endurance training of aerobic training on function of the heart as a pump in male university student this research measured stroke volume (SV) and cardiac output (CO) in twenty male university students before,after six weeks and after eight weeks training separately.The results showed that SV and CO increased significantly following six or eight weeks endurance training and that SV and CO increased significantly only following eight weeds strength-endurance training.These results demonstrated that short-term endurance and strength-endurance training all enhance function of the heart as a pump,in which there was different training time threshold from training items.
