摘要
目的 :探讨高原训练对优秀游泳运动员的VO2 max、BLA和T/C值及VO2 max相关指标的影响。方法 :16名游泳运动员 (男 7名 ,女 9名 )进行为期 9周的高原训练 ,分别在上高原前 1周、下高原后第 1周、第 2周和第 3周测定VO2 max、BLA和T/C值及VO2 max相关指标。VO2 max测定采用功率自行车递增负荷运动方案 ,起始负荷为 5 0W、转速 6 0～ 70r/min ,男子运动员递增 4 0W/ 3min ,女子运动员递增 30W/ 3min ,转速不变。结果 :上高原前和下高原后VO2 max、BLA和T/C值及VO2 max相关指标发生变化 ,但变化的时间和程度不同 ;且男、女游泳运动员的VO2 max、BLA和T/C值及VO2 max相关指标发生不同变化。结论 :高原训练对游泳运动员的VO2 max、BLA和T/C值及VO2 max相关指标产生影响 ,经过下高原后 17天的训练 ,运动员多数指标能够恢复至上高原前水平 ,并在相同运动负荷下BLA值降低 ,表明高原训练下高原后 17天游泳运动员的运动能力提高。
Objective To study the influence of altitude training on VO 2max, BLA, testosterone/ cortisol (T/C) and related indexes of VO 2max in elite swimmers. Methods Sixteen swimmers (7 males and 9 females) took part in altitude training for nine weeks. The values of VO 2max, BLA, T/C ratio were determined 1 week before altitude training, and 1st week, 2nd week, 3rd week after altitude training. VO 2max was tested on cycle egormeter with incremental protocol, the initial load was 50W, 60～70r/min, increased 40W/3min for male and 30W/3min for female. Results There were changes in VO 2max, BLA, T/C ratio and related indexes before and after altitude training. The changes were characterized by different timing and degree of the variation. There were also differences between male and female swimmers. Conclusion The most significant finding in this study was that the BLA level decreased 17 day after altitude training when swimmers performed exercise test with the same work load, showing that the anaerobic threshold of the swimmers improved through altitude training.
