【摘要】：目的:探讨间歇期不同恢复手段对青年男子篮球运动员高强度间歇训练(HIT)时运动能力以及有氧、无氧代谢供能的影响,为科学制定训练计划提供依据。方法:20名青年男子篮球运动员自愿参加本实验。受试者先利用递增负荷实验测定最大摄氧量(maximal oxygen uptake,VO2max)和最大功率输出(maximal power output,Wmax),择日进行3次HIT(以110%Wmax强度蹬车至力竭,间歇5 min,重复4组),间歇期对应3种不同的恢复方式,即以20%VO2max对应的功率继续蹬车(即积极性恢复,HITA)、下肢牵张运动(HITS)以及在功率车上安静休息(即消极性恢复,HITP)。实验过程中分别测定做功量、力竭时间、VO2、VO2动力学、氧亏积累(AOD),以及血乳酸含量([La])。结果:与HITS和HITP比较,HITA做功量、峰值摄氧量(VO2peak)、平均摄氧量(VO2mean)和总摄氧量(VO2total)升高(P0.05),VO2动力学时间常数(TC)降低(P0.05);力竭时间、AOD和血[La]在HITA、HITS和HITP间均无显著性差异(P0.05);HITS与HITP比较上述各指标均无显著性差异(P0.05)。结论:HIT间歇期进行积极性恢复对于运动能力的效果优于消极性恢复以及牵伸运动,其机制可能与积极性恢复时有氧代谢能量输出增加有关,VO2动力学加快和氧利用率提高是有氧供能增加的原因之一。
[Abstract]:Objective: to investigate the effects of different recovery methods on the exercise ability, aerobic and anaerobic metabolism of young male basketball players during high intensity intermittent training, and to provide scientific basis for the formulation of training plan. Methods Twenty young male basketball players volunteered to participate in the experiment. The maximal oxygen uptake and maximal power output were measured by incremental load test. The three times of hit (cycling to exhaustion with 110Wmax intensity, intermittent 5 mins, repeating 4 groups) were performed on a selective day, and the interval period was corresponding to three different recovery modes. That is to say, with the power corresponding to 20 / V _ 2max to continue riding (that is, positive recovery with HITAA, lower extremity distraction exercise with HITSs) and rest quietly in the power car (that is, negative recovery). During the experiment, the amount of work done, the time of exhaustion, the kinetics of VO _ 2, the accumulation of oxygen deficiency and the content of blood lactic acid ([La]) were determined respectively. Results: compared with hits and HITP, the amount of work done by Hita, Peak oxygen uptake (VO _ 2peaka), mean oxygen uptake (VO _ 2 mean) and total oxygen uptake (TCC) increased (P _ (0.05) V _ (2) O _ 2) decreased P _ (0.05) O _ (2), and there was no significant difference in exhaustion time (AOD) and blood [La] between HITA-HITS and HITP. There was no significant difference between the above indexes. Conclusion the effect of positive recovery on exercise ability during the interval of the percent hit is better than that of negative recovery and draft exercise. The mechanism may be related to the increase of oxygen metabolism energy output and the increase of VO2 kinetics and oxygen utilization ratio, which may be one of the reasons for the increase of aerobic energy supply.
