Limiting venous blood flow restriction is a new approach of training aims to improving high level of performance among athletes, which has shown prominent results at muscle hypotrophy and strength. KAATSU[1] is a training system including pressure belt imposed on the proximal part of the upper and lower bodies. The present study aims to investigate the effect of HIIT Kaatsu trainings on anaerobic performance among young athletes. The present quasi experimental research was conducted through a pre-test and post-test and three groups including KAATSU intensive interval exercises (n=11), intense interval exercise (n=9) and a control group (n=10). The exercises included running distances of 20 and 40 meters. In the beginning of the protocol most of the exercises was in short distances and as the sessions proceeded, the number of the sets and repetitions increased and it reached to its highest intensity in the last session. During the exercise protocol, intensity of training was considered to be the highest running speed and based on their abilities each individual tried to run as fast as possible. The exercise load was defined based on repetitions and the sets. In the 20 meters distances, the participants took a ten second rest after each repetition and a one minute rest after each set and in 40 meters distances; Subjects took a 20 second rest after each repetition and 2 minute rest between sets. The control group did not performed any of the mentioned exercises. Moreover, before and after four weeks of training the individuals were given RAST and Anaerobic Biking Wingate Test. Statistical result has been shown, there is a significant change between the maximum anaerobic power in Wingate biking test after four weeks within KAATSU intensive interval (P≥ 0.05) and intensive interval (P≥ 0.05) groups, but no significant change was detected in the control group (P> 0.05). The statistical analysis of this research has been shown that there is of current investigation indicated that compared to intensive interval exercise alone, attending the KAATSU intensive exercises is more effective on the highest anaerobic power ( Wingate bike) and the lowest as well as the average of anaerobic power.

高强度间歇训练及限血对无氧运动能力的影响

限制静脉血流限制是一种旨在提高运动员高水平表现的新训练方法，在肌肉萎缩和力量训练方面已显示出显著成果。KAATSU [1]是一种训练系统，包括施加在上，下身近端部分的压力带。本研究旨在调查HIIT Kaatsu训练对年轻运动员厌氧表现的影响。目前的准实验研究是通过预测试和后测试以及KAATSU强化间歇运动（n = 11），剧烈间歇运动（n = 9）和对照组（n = 10）三组进行的。练习包括20和40米的跑步距离。在协议开始时，大多数练习都是近距离进行的，随着会议的进行，集合和重复的次数增加了，在上一届达到了最高强度。在锻炼方案中，训练强度被认为是最高的奔跑速度，并且根据他们的能力，每个人都试图尽可能快地奔跑。运动负荷是根据重复次数和集合来定义的。在20米的距离内，参与者在每次重复后休息10秒钟，每组在40米的距离后休息1分钟。每次重复后受试者休息20秒，两次休息之间休息2分钟。对照组没有进行任何上述锻炼。此外，在训练四个星期之前和之后，对个体进行RAST和厌氧性自行车Wingate测试。统计结果已经显示，在KAATSU强化间隔（P≥0.05）和强化间隔（P≥0.05）组内的四个星期后，Wingate自行车测试中的最大厌氧能力之间没有显着变化，但对照组（P > 0.05）。对这项研究的统计分析表明，目前的调查表明，与仅进行密集间隔锻炼相比，参加KAATSU密集锻炼对最高无氧力量（温盖特自行车），最低和平均无氧力量更为有效。无氧能力。
