坐式排球运动员心脏结构与心肺机能的研究

Study on the sitting volleyball athletes cardiac construction and cardiopulmonary function

运用超声心动图技术与时间肺活量测试,对我国坐式排球运动队队员的心脏结构和心肺机能进行检查,了解长期的坐式排球运动训练对他们的心脏结构和心肺机能可能产生的影响。结果显示:坐式排球运动员的左心室后壁厚度明显增厚,但左心室内径变化不明显;射血分数、左室内径缩短率与左室周径缩短率均明显低于普通残疾人,其使心脏具有了较高的心力储备;肺活量与时间肺活量均明显高于普通残疾人。

By the means of Echo & T-lvc to test our country sitting volleyball athletes cardiac construction and cardiopulmonary function, it is to learn that the long period sports of the sitting volleyball has an effect on their cardiac construction and cardiopulmonary function. It shows: The sitting volleyball athletes LVPW becomes thick, but the LVID has no evidently change. All of the EF, % AD and MVCF three indexes are inferior to those of the average disabled people, which implies that the sitting-volleyball athletes & acute, hearts have the greater reserve than those of the average disabled people; Both lvc and T-lvc and T-lvc are obviously superior to their counterparts..
