采用逐级递增负荷踏车试验测定26名运动员最大摄氧量与无氧阈并与在相应心率下二维超声心动图运动试验测得的左心室形态和机能各参数比较。左室舒末内径与(?)O_(2max)、左室泵血功能某些参数在AT和AT以上和(?)O_2有显著相关,但不同个体在相应心率下相关较低,而同一个体(或组)在整个试验过程中自身比较呈高度相关。 Twenty-six athletes’ maximum oxygen uptake and anaerobic threshold were measured by progressive treadmill treadmill test and compared with the left ventricular morphology and function parameters measured by two-dimensional echocardiography test at corresponding heart rate. Left ventricular end-diastolic diameter and (?) O_ (2max), left ventricular blood function parameters AT and AT above and (?) O_2 were significantly correlated, but different individuals in the corresponding heart rate was lower, while the same individual (Or groups) themselves were highly correlated throughout the experiment.
