| 摘 要： | 本文采用运动训练、减量训练、停止训练相结合的实验方法,通过阻抗心动图的测定,分别对A、B两组青春期少年的左心功能变化进行了纵向研究.结果发现经过3个月的定量训练两组少年的心脏工作能力均有显著提高,且A组减量训练一个月后仍保持较高的水平,但B组停训一个月后则表现出明显的回降.由此显见,青春期少年的心脏对运动刺激有着较高的敏感性和机能可塑性,这对正确指导青少年的体育锻炼和运动训练具有重要的理论和实践意义.

A STUDY ON VENTRICULAR FUNCTION-AL PLOSTICITY OF PUBESCENT JUVE-NILE |

| Abstract: | In this paper, we used the experme-nt method of sport training, reduced training or detraining combined, detrminated the impedance cardiogram and studied the left ventricalar funtion changes in two groups pubecent juveniles longitudinallyTheresult indicated that the ventricular function of two groups of pubescent juveniles was improved prominently in the determinable training for three monthsand group A still kept on a high-er level afterone month reduled training. GroupB delined prominently after one month detraining, It shows that the heart of pubescent juvenlile has higher sensitivity and functional plasticily to trainingincentives. This study has importent theoretical and practical significance forinstructing youngster's sport training and physical exercise properly. |
