对60个人包括17名举重运动员(CWL)、12名长跑运动员(LDR)、7名举重业余爱好者(AWL)、14名重级别对照者(HC)和10名轻级别对照者(LC)的左心室质量用超声心动描记器进行研究。两组比赛运动员与对照者对比,左心室质量(LVM)的绝对值增加了(LDR:195±12;CWL:190±10;LC:122±10;HC:151±9克)。AWL质量介于比赛运动员和对照组之间。左心室质量与全身肌肉质量之比(归一化(注)),发现了各组之间的一个显著的(显著水平P=0.038)相关,尽管相关系数是低的(r=0.276)。长跑运动员明显地较高,举重运动员和重级别对照者几乎相等(LDR:3.2±0.2;CWL:2.6士0.1;AWL:2.5±0.2;HC:2.3±0.2;LC:20.±0.2克)。这些资料表明,长跑训练(动力训练)可提高左心室质量;而举重训练(静力训练)仅仅是在肌肉质量增长的相应程度上使左心室质量增长。
A total of 60 individuals including 17 weightlifting athletes (CWL), 12 distance runners (LDR), 7 weight lifting amateurs (AWLs), 14 weight class HCs and 10 light weight LCs Left ventricular mass was studied by echocardiography. The absolute values of left ventricular mass (LVM) increased (LDR: 195 ± 12; CWL: 190 ± 10; LC: 122 ± 10; HC: 151 ± 9 g) in both athletes and controls. The quality of AWL ranged from competition athlete to control group. The ratio of left ventricular mass to total body mass (normalized (Note)) revealed a significant (significant level, P = 0.038) correlation among groups, although the correlation coefficient was low (r = 0.276). Long distance runners were significantly taller, weight exercisers were almost equal to those of the heavier weight class (LDR: 3.2 ± 0.2; CWL: 2.6 ± 0.1; AWL: 2.5 ± 0.2; HC: 2.3 ± 0.2; LC: 20. ± 0.2 g). These data show that long-distance training (power training) can improve left ventricular mass; and weight training (static training) only in the corresponding increase in muscle mass to make the left ventricle mass growth.
