【摘要】 对国家花样游泳队 4 3名运动员于 2 0 0 3年 10月的高原训练进行全程跟踪 ,并测试相关生理生化指标 ,结果发现 ,上高原后 ,运动员Hb、T、RBC、HCT、WBC等指标均稳步上升 ,尤其是Hb、RBC、HCT ,在上高原后第 2周明显升高 ,与刚上高原比较均有非常显著性差异 (P <0 0 0 1)。与第 2周比较 ,第 3周升高幅度较小 ,但睾酮显著升高 ,上述指标在第 4周达到较高值。CK的高值出现在上高原后第 2周 ,为 2 0 8 33± 92 2 6U/L ,第 3周、第 4周则持续下降。WBC数无显著变化 ,但有上升趋势 ,提示运动训练负荷不高。建议高原训练时 ,在血红蛋白出现第 1次峰值时 ,可考虑增加运动负荷 ,尤其是运动强度 ,以达到提高机体潜能、强化提高体能的目的。更多还原

【Abstract】 During one month altitude training, physiological and biochemical indicator were tested in 43 Chinese synchronized swimming athletes. The results showed that Hb , T, RBC, HCT, WBC were all increased, especially Hb, RBC, HCT increased signifi cantly in the second week. Comparing with the second week, the increased amplitu de in the third week declined, but T remained at high level. These parameters re ached peak and ideal level in the fourth week. Peak CK was found in the second w eek(208.33±92.26 U/L), then declined, indicating the exercise intensity after t he second week was inadequte. Results suggested that exercise intensity should b e increased when Hb reached to it’s peak level so as to improve the potential p hysical performance.更多还原
