根据美国运动医学会专业会员MikeLeung的研究发现，运动后心脏恢复率（heartrecoveryrate）是一个有效的健康标准。持续地进行长时间运动以后，心脏分两个阶段恢复。在最初阶段，心率急剧下降，接着维持一定状态。在心率图上是一个水平线段。然后，慢慢地恢复到原来安静时的心? According to a study by Mike Leung, a member of the American College of Sports Medicine, cardiac recovery after exercise is an effective standard of health. After a long period of sustained exercise, the heart is recovered in two stages. During the initial period, the heart rate dropped sharply and then maintained a certain state. On the heart rate graph is a horizontal line. Then, slowly recover to the original quiet heart?
