Echocardiographic dimensions, anthropometric data and maximal oxygen uptake (VO2max) were studied in 26 healthy sedentary male controls (mean age, 22.0 yrs) and 15 male endurance athletes (mean age, 20.3 yrs). Athletes displayed significantly greater mean values for left ventricular internal dimension at end-diastole (LVIDd), end-diastolic volume (LVEDV) and left ventricular mass (LVM). Statistically significant positive correlations were observed within the sedentary control group between left ventricular end-diastolic dimensions (LVIDd, mm and/or LVEDV, cm3) and body height (cm), body weight (kg), chest circumference (cm) and body surface area (m2). Left ventricular mass (LVM, g) correlated significantly with lean body mass (kg). Ectomorphic somatotype rating (Ecto) correlated negatively with LVEDV and LVM. Finally, VO2max (l/min) correlated significantly with LVIDd, LVEDV and LVM. Multiple linear regression analysis indicated that the degree of endomorphy (Endo), LVIDd (mm/m2) and chest circumference accounted for 89% of the variance in VO2max (ml/kg/min) within the athlete group. Endo, Ecto and LVIDd (mm/m2) accounted for 86% of the variance in VO2max (ml/kg/min) in the control group. This study supports the hypothesis that maximal aerobic power can be predicted from cardiac and anthropometric measurements.
对26名健康久坐男性对照组（平均年龄22.0岁）和15名男性耐力运动员（平均年龄20.3岁）进行了超声心动图测量、人体测量数据和最大摄氧量（VO2max）研究。运动员的舒张末期左心室内径（LVIDd）、舒张末期容积（LVEDV）和左心室质量（LVM）的平均值显著更高。在久坐对照组中，左心室舒张末期尺寸（LVIDd，mm和/或LVEDV，cm3）与身高（cm）、体重（kg）、胸围（cm）和体表面积（m2）之间存在统计学上显著的正相关。左心室质量（LVM，g）与瘦体重（kg）显著相关。瘦长体型评分（Ecto）与LVEDV和LVM呈负相关。最后，VO2max（l/min）与LVIDd、LVEDV和LVM显著相关。多元线性回归分析表明，在运动员组中，内胚层体型程度（Endo）、LVIDd（mm/m2）和胸围占VO2max（ml/kg/min）方差的89%。在对照组中，Endo、Ecto和LVIDd（mm/m2）占VO2max（ml/kg/min）方差的86%。本研究支持从心脏和人体测量指标预测最大有氧能力的假设。
