| 摘 要： | 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.

| Abstract: | The heart rate drift phenomena occur to a different extent in all subjects (footballers) during steady endurance running either at the sea level or at the altitude, but the heart rate indexes at the altitude was higher than those at the sea level. The difference of heart rate drift phenomena existing in subjects with different physical performance reflects the difference of maximal oxygen uptake to a certain extent. The increase of serum cardiac muscular isoenzyme at the sea level and at the altitude indicates that the heart rate drift phenomenon has intensive stimulus effects on cardiac muscles, accompanied with slight anoxic cardiac muscular injury. This symptom is even more obvious at the altitude. |
