经常的运动训练能使正常健康人心脏发生某种程度的适应。这种适应现象有时亦见于冠心病患者并使他们增强工作能力。显然,练习对冠心病也能起到某些预防作用。许多研究者指出。长期运动训练可产生心率的适应性,包括安静时心率缓慢,以及在标准极限下工作负荷的心率减慢。最大心率是否受训练的影响还有争论。训练使最大心率减慢通常发现在青年受试者,开始心率每分钟约高于180次,年纪大一些受试者最大心率减慢变化不大,或者没有变化。心脏本身有自主性节律,但在正常 Regular exercise training can make the heart of normal healthy people to some degree of adaptation. This adaptation is sometimes seen in patients with coronary heart disease and enable them to enhance their ability to work. Obviously, practice can play some preventive role in coronary heart disease. Many researchers point out. Long-term exercise training can produce heart rate adaptability, including slow heart rate at rest, and a slower heart rate at work load at standard limits. Whether the maximum heart rate is affected by the training is still controversial. Training slowed the maximum heart rate is usually found in young subjects, heart rate began more than about 180 times per minute, older subjects some of the maximum heart rate slowed little change, or no change. The heart itself has an autonomic rhythm, but it is normal
