Sixty individuals including 17 competitive weight lifters (CWL), 12 competitive long-distance runners (LDR), 7 amateus (noncompetitive) weight lifters (AWL), 14 heavy controls (HC), and 10 light controls (LC) were studied at supine rest with echocardiographic determination of the left venticular mass (LVM) by the Penn convention. Lean body mass (LBM) was estimated by the Wilmore-Behnke method. The absolute LVM (mean +/- SE) was increased in the two competitive athlete groups compared to controls (LDR: 195 +/- 12; CWL: 190 +/- 10 vs. LC: 122 +/- 10; HC: 151 +/- 9 g). The AWL had a mass (174 +/- 20 g) intermediate between the LDR-CWL and the HC-LC groups. A significant (P = 0.033) correlation of LVM was found with LBM although the correlation coefficient was low (r = 0.276). Normalizing LVM by LBM revealed a significantly higher mass for LDR compared to all other groups but equalized CWL and HC (LDR: 3.2 +/- 0.2; CWL: 2.5 +/- 0.1; AWL: 2.5 +/- 0.2; HC: 2.3 +/- 0.2; LC: 2.0 +/- 0.2 g). These data suggest that training for competitive long-distance running (dynamic training) elevates LVM compared to nonathletic controls and CWL. On the other hand, training for weight lifting (static training) increases absolute LVM but only to the extent that LBM is increased.
研究对象包括60人，其中有17名竞技举重运动员（CWL）、12名竞技长跑运动员（LDR）、7名业余（非竞技）举重运动员（AWL）、14名体重较重的对照组人员（HC）和10名体重较轻的对照组人员（LC）。研究人员让这些人员在仰卧休息状态下接受检查，采用宾夕法尼亚州立大学的标准通过超声心动图测定左心室质量（LVM）。瘦体重（LBM）采用威尔莫尔 - 本克方法估算。与对照组相比，两个竞技运动员组的绝对LVM（平均值±标准误）有所增加（LDR：195±12；CWL：190±10，而LC：122±10；HC：151±9克）。AWL的质量（174±20克）介于LDR - CWL组和HC - LC组之间。尽管相关系数较低（r = 0.276），但发现LVM与LBM之间存在显著相关性（P = 0.033）。通过LBM对LVM进行标准化处理后发现，与所有其他组相比，LDR的质量显著更高，但CWL和HC的质量相当（LDR：3.2±0.2；CWL：2.5±0.1；AWL：2.5±0.2；HCHC：2.3±0.2；LC：2.0±0.2克）。这些数据表明，与非运动员对照组和CWL相比，竞技长跑训练（动态训练）会提高LVM。另一方面，举重训练（静态训练）会增加绝对LVM，但仅在LBM增加的程度上。
