Multi-stage fitness test
The test requires participants to run 20 meters back and forth across a marked track keeping time with beeps.Every minute or so, the next level commences: the time between beeps gets shorter; participants must run faster.The maximum laps on the PACER test is 247,[1] which former Central Middle School student Dennis Mejia achieved,[2] the only person to ever reach such a level.The test is used by sporting organizations around the world along with schools, the military, and others interested in gauging cardiovascular endurance, an important component of overall physical fitness.[5] The multi-stage fitness test was first described by Luc Léger[6] with the original 1-minute protocol, which starts at a speed of 8.5 km/h, and increases by 0.5 km/h each minute.Additionally, the test's prediction of aerobic capacity is valid for most individuals, including those who are overweight or obese.Notes: The distance between the "start" and "turn around" markers is usually 20m; however, the test can also be carried out using a 15m track.Do note that such estimations are fraught with difficulty as test scores, while substantially dependent on VO2 max, also depend on running efficiency, test familiarity, anaerobic capacity, personal drive, ambient temperature, running equipment (floor, shoes) and other factors.The impact of this variation is purely administrative: just add or subtract 1 level to convert scores.The Guinness World Record for the largest group beep test is held by Army Foundation College, in Harrogate, North Yorkshire; 941 people took part.
