八个业余俱乐部网球运动员进行两个溜溜球IR2测试在三个不同的场合。所有八个参与者被男性和18到35岁之间。参与者被招募在当地一家网球俱乐部,每周至少两次。参与者被问及他们ITN数量;这是一个国际网球数字代表一个球员的整体水平。数量从1到10,10代表初学者和1代表一个职业网球选手。平均值和标准偏差的年龄、身高和体重计算。参与者被免于心血管、呼吸道、osteomuscular和代谢疾病。他们都是体力活动,然而他们并不参与具体的训练计划。参与者没有烟雾或采取任何药物。每个参与者提供书面知情同意和被告知所有的不适和风险。这项研究是大学研究伦理委员会批准。
溜溜球IR2测试是由Bangsbo哥本哈根大学的。它是一个有效的和可靠的测试测量无氧能力的个体(Krustrup et al .,2006)。溜溜球IR2测试由2 a-20m航天飞机以不断增长的速度运行,结合十秒时间内积极的复苏(由音频信号从cd机)(Bangsbo Iaia & Krustrup,2008)。这是一个非常实用的测试,很容易没有测试在实验室繁殖。溜溜球IR2测试是一种更合适的训练比溜溜球IR1个人测试,因为它是从一个更高的平均运行速度。溜溜球IR2由多个阶段,十五。第一阶段涉及一个航天飞机运行速度为13.0(公里/小时),第二阶段15公里/小时的速度,一个航天飞机运行。平均速度增加到16公里/小时,迫使参与者运行两个航天飞机,16.5 km / h和17公里/小时,需要三个和四个航天飞机。而且接下来的十阶段逐步上升到0.5公里/小时,每个阶段需要八个航天飞机完成。能够达到的最大速度和距离是22公里/小时和3.64公里。

Eight amateur club level tennis players performed two Yo-Yo IR2 tests on three separate occasions. All eight participants were male and between 18-35 years old. The participants' were recruited at a local tennis club and played at least twice a week. The participants were asked their ITN number; this is an international tennis number that represents a player's general level of play. The number goes from 1-10, 10 representing beginners and 1 representing a professional tennis player. The mean and standard deviation of age, stature and body mass were calculated. Participants were free from cardiovascular, respiratory, osteomuscular and metabolic diseases. They were all physically active, however they did not engage in a specific training schedule. The participants did not smoke or take any medication. Each participant provided written informed consent and was informed of all the discomforts and risks. The study was then approved by the university research ethics committee.
The Yo-Yo IR2 test was created by Bangsbo at the university of Copenhagen. It is a valid and reliable test for measuring anaerobic capacity of an individual (Krustrup et al., 2006) . The Yo-Yo IR2 test consists of 2Ã-20m shuttle runs at ever-increasing speeds, combined with a 10-second period of active recovery (regulated by audio signals from a compact-disc player) (Bangsbo, Iaia & Krustrup, 2008). It is a very practical test and is easy to reproduce without to test in a laboratory. The Yo-Yo IR2 test is a more suitable to trained individuals than the Yo-Yo IR1 test as it starts at a higher average running speed. The Yo-Yo IR2 consisted of multiple stages, fifteen in all. The first stage involved one shuttle run with a speed of 13.0 (km/hr), the second stage a speed of 15km/hr and one shuttle was run. The average speed increased to 16 km/h, necessitating the participants to run two shuttles, 16.5 km/h and 17 km/hr which required three and four shuttles. Furthermore the next ten stages went up incrementally by 0.5 km/hr, with each stage requiring eight shuttles to be completed. The maximum speed and distance that could be achieved was 22km/hr and 3.64km.
