摘要
目的:探讨不同海拔交替训练对运动员生长激素和胰岛素样因子-I的影响。方法:长期生活在平原的男子运动员19人,分为两组:高原-平原交替训练组和高原-亚高原交替训练组。采用放射免疫法测试血清生长激素和胰岛素样因子-I的变化情况。结论:(1)通过两个阶段的交替训练,两个组运动员的GH和IGF-I变化幅度减小,运动员对于低氧刺激的调节能力增强了,有利于运动员更好的适应训练。(2)高原-亚高原组第二阶段GH、IGF-I整体水平要高于高原-平原组,表明在亚高原训练后可以更好的过渡到高原进行训练,减少运动员的适应期,有利于运动员在高原期间的训练。
Objective： To explore the effect of the different altitude alternate training on serum GH and IGF-I of athletes. Methods： Male athletes, living in plains, n=19（Altitude-plain alternate training group, APG; altitude-sub-altitude group, ASG）. The changes of serum growth hormone and insulin-like factor-I were test by radioimmunoassay. Conclusion：（1） The range ability of the concentration of serum GH and IGF-I of athletes of the two groups decrease at the end of two stages. The ability of athletes to regulate hypoxic stimulation enhanced, to better adapt to the athletes training.（2） Compared with the APG, the concentration of serum GH and IGF-I was higher in ASG. So, sub-altitude training can serve as the transition period before altitude training. After sub-altitude training, the adaptation period was shorter.
