摘要
旨在通过不同氧浓度的高住高练低训,观察足球运动员红细胞等血象指标的变化。实验对象为北京体育大学足球专项的男生16人,随机分为高住高练低训组和低住低训组。实验分2次进行。第1次实验的氧浓度为15.4%(相当于海拔2500m所对应的氧浓度);间隔一年后进行第2次实验,氧浓度为14.2%(相当于海拔3000m所对应的氧浓度)。每次低氧暴露期为1个月,在低氧暴露前、低氧暴露10h、低氧暴露2周末、3周末和4周末等不同低氧暴露持续时间的清晨取血样。研究结果表明,氧浓度为14.2%的高住高练低训与15.4%相比,能更快更有效地提高红细胞和血红蛋白的生成。
This paper analyzed the change of hematology parameters of soccer players through the training of HiHilo at different oxygenic level. Sixteen male students majoring in soccer were divided into living high-exercise and high training low group and living low and training low group randomly with two times experiment. The first experiment was at condition of 15. 4% oxygenic level ,equivalent to 2 500 m above sea level. One year later,the second experiment was made at condition of 14.2% oxygenic level ,equivalent to 3 000 m above sea level. The duration of hypoxia was one week each time. The blood sample was taken in the morning before hypoxia and after 10 hours,two weeks,three weeks and four weeks hypoxia. The result showed that comparing with 15.4% oxygenic level,the 14.2% oxygenic level could improve erythropoiesis and hemoglobin production more quickly and effectively.
