摘要：Determining the recovery heart rate (RHR) index after various submaximal exercises is a popular and practical way for a population’s cardiovascular fitness evaluation. These evaluations are based on the regression among RHR, load intensity, and maximal oxygen uptake. However, little work has been done to 1) explore the influences of body weight and height on these tests’ reliability and sensitivity, and 2) compare the reliability among the tests. As a result, practitioners often choose tests without the appropriate criteria. This study researched the mentioned two aspects by evaluating 30 male college students via three common tests – 30 cm step test, 40 cm step test and squat-up-down test. The results showed that the reliability and sensitivity of the three tests were remarkably different. Adding body weight into the evaluation would improve both reliability and sensitivity. Considering all the influence factors, 30 cm step test was the best one. These findings suggested that applying the relative RHR index (normalized by body weight) should be considered for a population’s cardiovascular fitness evaluation in the future.
