| 摘 要： | 两年游泳系统训练后,男女运动员ＶＯ２ｍａｘ绝对值和相对值都无显著性变化,无氧阈明显提高。表明,ＡＴ的显著改善并不需要ＶＯ２ｍａｘ明显提高。训练后,ＡＴ和心泵血功能都有显著性提高,并且ＣＯ与ＡＴ的相关比ＣＯ与ＶＯ２ｍａｘ相关更为密切,提示,ＡＴ提高与心泵血功能变化有关,心功能可能是影响ＡＴ的重要因素。训练使心脏舒张功能得以改善,这是心脏对运动的又一适应。

| Abstract: | This study is to examine effects of systematic training on anaerobic threshold(AT),maximal oxygen uptake(VO2max),and the systolic and diastolic function of left ventricle,and to find out the relationship between the changes in cardiac function and AT during training.The results of the study showed that both VO2max(1/min)and VO2max(ml/min.kg)didn't change evidently after 2 years swimming systematic training, but AT and systolic function markedly increased.And the correlation between cardiac output(CO)and AT was significant(R=0.85)more than between CO and VO2max(R=0.65).The results suggested that there is a relationship between AT and cardiac function.Cardiac function is likely an important reason for effecting of AT.Training can improve diastolic function of left ventricle. This is another suite for heart. |
