Development of a method to measure the intermittent anaerobic power as a field test.

本研究的目的是建立一种通过现场测试来测量间歇无氧功率的方法。这项研究使用了间歇性的航天飞机冲刺测试(我们称之为ISST)，包括一次40米的冲刺。第一项研究比较了两次20米的40米冲刺和8次5米的40米冲刺的结果。每两个20米的航天飞机的冲刺速度下降的速度与有氧能力显著相关。第二项研究使用了ISST，参与者也进行了40米的短跑，由两个20米的航天飞机组成，每次冲刺之间的间隔为10秒，总共10次。短跑速度在第6冲刺时逐渐下降，此后没有进一步的实质性变化。0-15米短跑速度下降率与无氧能力显著相关，25-40米短跑速度下降率与空气…显著相关第三项研究检验了ISST的发现，在这项研究中，在20秒内用两次20米的航天飞机进行40米冲刺，重复10次。这台ISST是为了在野外测量许多受试者的无氧功率而开发的。关于ISST的重复性，第5短跑时的速度下降率的相关系数为0.820。此外，短跑速度的平均下降率与4-10步的有氧能力显著相关。最后一项研究考察了ISST、有氧能力、无氧能力之间的关系，以及由40m短跑和25m跑组成的比赛耐力测试，并在间歇时间内改变方向与休息和各种动作进行了比较。在下半场的耐力测试中，较好的有氧能力往往与较低的速度下降有关。此外，与40米短跑和25米换向跑的最佳速度相比，ISST的速度下降率较低，与较高的相对速度相关。这些结果表明，新开发的ISST是一种简单而准确的测试方法，可以用来评估运动员的间歇性无氧能力。较少

The purpose of this study was to develop a method for measuring the intermittent anaerobic power by means of a field test. This study used an intermittent shuttle sprint test (which we named ISST) which consisted of a 40 meter sprint.The 1st study compared the results of a 40 meter sprint with 2 shuttles of 20 meters each and a 40 meter sprint with 8 shuttles of 5 meters each. The rate of decrease in the sprint speed for each 2 shuttles of 20 meters significantly correlated to the aerobic capacity.The 2nd study used ISST in which the partcipants also ran 40 meter sprints, consisting of 2 shuttles of 20 meters each, a total of 10 times at an interval of 10 seconds between each sprint. The sprint speed deceased gradually until the 6th sprint and thereafter showed no further substantial changes. The rate of decrease in the 0-15 meter sprint speed significantly correlated to the anaerobic capacity and the rate of decrease in the 25-40 meter sprint speed significantly correlated to the aero … More bic capacity.The 3rd study examined the ISST findings in which a 40 meter sprint with 2 shuttles of 20 meters within 20 seconds was repeated 10 times. This ISST was developed to measure the anaerobic power of many subjects in the field. Regarding the reproducibility of ISST, the correlation coefficient was 0.820 in the rate of decrease of sprint speed at the 5th sprint. In addition the rate of the average decrease in the sprint speed significantly correlated to the aerobic capacity during sprints 4 through 10.The last study was an examination of the relationships among ISST, aerobic capacity, anaerobic capacity, and the game stamina test which consited of a 40 meter sprint and a 25 meter run performed while changing directions with rest and various movements during the interval time. A superior aerobic capacity tended to be associated with a lower speed decrease in the 2nd half of the game stamina test. In addition, the lower rate of speed decrease in the ISST correlated with a high relative speed in comparison to the best speed in the 40 meter sprint and 25 meter run while changing directions.These results suggest that the newly developed ISST thus appears to be a simple and accurate test for evalutating the intermittent anaerobic power of individuals in the field.
