以航空航天医学对海拔高度区域的划分为依据,以SD大鼠为实验对象,观察摸拟海拨4000米高原训练前后大鼠血清肌钙蛋白T(cTn-T)的浓度变化。结果表明,模拟海拔4000米,为期4周,每周7天,每天1小时的游泳训练未造成大鼠心肌不可逆转的严重损伤,且心肌重量较高原对照组有所增加,大鼠心肌产生了适应性变化。单独处于海拔4000米高度的低氧环境未引起大鼠血清肌钙蛋白明显升高,而低氧加训练双重影响导致cTn-T显著增加。 Based on the division of altitude and altitude in aerospace medicine, SD rats were used as experimental subjects to observe the change of serum concentration of troponin T (cTn-T) before and after altitude 4000 m altitude training. The results showed that simulated 4 000 m altitude, 4 weeks, 7 days a week, 1 hour a day of swimming training did not cause irreversible myocardial damage in rats, and the higher myocardial weight of the control group increased, the rat myocardium produced Adaptability changes. Hypoxia alone at an altitude of 4,000 meters did not cause a significant increase in serum troponin in rats, while the double effect of hypoxia plus training resulted in a significant increase in cTn-T.
