Multi-stage fitness test

The multi-stage fitness test, also known as the bleep test, beep test, pacer test, Leger-test or 20-m shuttle run test, is a series of stages that have different tasks sometimes used by sports coaches and trainers to estimate an athlete's VO₂ max (maximum oxygen uptake).The pacer test is "progressive aerobic cardiovascular endurance test". The test is especially useful for players of sports such as rugby, football, Australian rules football, Gaelic football, hurling, hockey, netball, handball, tennis, squash, and fitness testing in schools and colleges plus many other sports; employed by many international sporting teams as an accurate test of cardiovascular fitness, one of the more important components of Fitness. The test was created in 1982 by Luc Léger, University of Montreal^[1] and published in 1983 with a starting speed of 8 km/h and stages of 2 min duration. The test was re-published in the European Journal of Applied Physiology in 1988 in its present form with a starting speed of 8.5 km/h and 1 min stages under the name "The multistage 20 metre shuttle run test for aerobic fitness".^[2] Result equivalences between slightly modified versions are well explained by Tomkinson et al. in 2003.^[3]

 VO2max = (velocity * 6.65 - 35.8) * 0.95 + 0.182 [4]
 vVO2max = VO2max / 3.5 [5]

Rules

The test involves running continuously between two points that are 20 meters apart from side to side. These runs are synchronized with a pre-recorded audio tape, CD or laptop software, which plays beeps at set intervals. As the test proceeds, the interval between each successive beep decreases, forcing the athlete to increase their speed over the course of the test, until it is impossible to keep in sync with the recording (or, on extremely rare occasions, until the athlete completes the test). Many people who test people using the multi-stage fitness test allow one level to beep before the person makes the line, but if the person being tested does not make the next interval then the most recent level they completed is their final score. The recording is typically structured into 21 'levels', each of which lasts around 62 seconds. Usually, the interval of beeps is calculated as requiring a speed at the start of 8.5 km/h, increasing by 0.5 km/h with each level thereafter. The progression from one level to the next is signaled by 3 quick beeps. The highest level attained before failing to keep up is recorded as the score for that test.

Format

The original beep test was initially available on audio tape format. A problem with the tape was that it could stretch over time, or the tape player would play at inconsistent speed, making the timing between beeps inaccurate. Most versions of the tape had a one-minute recorded interval for calibrating the tape and tape player. Digital audio formats replaced the tapes, but checks were still required on the CD/player due to some tone controls possibly affecting the playback speed.

Inexpensive beep test software is now popular due to modern electronic devices having excellent and consistent timing accuracy. The software generally runs on a portable electronic computer such as a tablet, phone or laptop, making the test easy to organise for teams, and also tracks player fitness over a season.

The contemporary accepted format starts at 8.5 km/h with levels of 1 minute as described in Leger's and Lambert's paper of 1988.^[2]
