足球运动员平原及高原匀速耐力跑时无论是在平原还是在高原所有受试者都不同程度地出现心率漂移现象。但高原各心率指标均高于平原。不同运动能力受试者所存在的心率漂移现象差异在一定程度上反映了最大摄氧能力差异。平原及高原血清心肌同功酶的升高表明心率漂移现象对心肌具有强烈刺激作用 ,并伴有轻度缺氧性心肌受损 ,在高原该症状更为明显。 In the plain and plateau run of the footballer, the subjects of heart rate drift appeared in varying degrees in both plain and highland. However, the heart rate indicators are higher than the plateau. The difference in heart rate drift between subjects with different motor ability reflects to some extent the difference in maximal oxygen uptake capacity. Elevated serum and myocardial isoenzyme levels in the plains and plateaus indicate that the phenomenon of heart rate drift has a strong stimulating effect on the myocardium accompanied with mild hypoxic myocardial damage, which is more pronounced at high altitude.
