摘要
高原训练作为一种提高运动员运动成绩的手段 ,目前在很多运动项目进行了尝试。为了探讨高原训练在游泳训练中的应用及生理机制 ,在我们以往多次游泳运动员高原训练的基础上 ,我们制定了这次赛前在昆明 (海拔 1890米 )的高原游泳训练计划。通过比较 5名优秀游泳运动员高原训练前 3周、高原训练 3周、高原训练后 3周共 9周训练期间 ,高原前、高原期间和高原后的血液学参数包括红细胞数、血红蛋白含量、红细胞压积、网织红细胞计数、血液促红细胞生成素含量、红细胞内 2 ,3 -二磷酸甘油醛含量等的变化 ,和高原训练前后 4mmol/L血乳酸运动强度的游泳速度与心率 ,发现运动员无氧阈游速增加 ,有氧代谢能力增强 ,乳酸耐受能力增强 ,血乳酸 -速度曲线右移 ,表明此次高原训练提高了游泳运动员的有氧运动员能力。
Altitude training as an effective had been adopted by many sports events, for the investigation of application of altitude training in swimming and it's physiological mechanism , we designed a swimming athletes altitude training protocol in KUNMING based on our several altitude training experience : 3 weeks sea level aerobic training as the preparation of altitude training , 3 weeks altitude training in KUNMING (1890m) , 3 weeks after altitude training . By the comparison of hematological index including blood red cell (RBC) hemoglobin content (Hb) hematocrit 2,3-glyceraldehyde phosphate blood erythropoietin before altitude training in altitude training and after altitude training , and also the comparison of swimming velocity and heart rate at 4mmol/L lactate intensity , the results is that after altitude training , athletes' swimming velocity at anaerobic threshold increasing , aerobic metabolism capacity increasing , velocity-lactate curve right shift , indicating the enhancement of aerobic performance of these athletes .
