# Measuring Maximal Aerobic Speed (MAS)

Maximal Aerobic Speed (sometimes called MAS, Maximum Aerobic Speed, Max Aerobic Speed and vVO_{2max}), is the slowest speed at which you reach VO_{2max}. This speed is used to help set running paces in training programs.

As per the definition, the maximal aerobic speed can be measured during a VO_{2max} Test. While performing an incremental VO_{2max} test, during the final stages, VO_{2max} may be reached while the treadmill speed continues to rise. By comparing the treadmill running speeds and the VO_{2} results, the slowest speed at which VO_{2max} was first reached can be determined. Typically, field sport athletes achive MASs of 4.4 to 4.8 m/s.

It is not always possible to perform a VO_{2max} test, and fortunately there are many other fitness tests that can be used to estimate Maximal Aerobic Speed. The tests listed below are not designed to specifically measure the maximal aerobic running speed, though that measure can easily be calculated from the test results. Depending on the test being used, the MAS can vary, and for some tests there is a correction factor needed to get a value closer to the actual MAS.

## Tests for Estimating Maximal Aerobic Speed

MAS is often calculated by performing a time trial of between 5 and 6 minutes, either as a set time (eg. 5-minute time trial) or over a set distance (eg. 1.5 to 2km). There are also incremental or shuttle tests that have been used to measure/calculate MAS.

- MAS run test - a maximal run over 1.5-2km, which should take between 5 and 6 minutes.
- VAMEVAL Test - running around a track at increasing speeds
- 5-min running field test (Berthoin et al. 1997) - Measure the distance covered in that time to calculate MAS.
- University of Montreal Track Test - the original beep test, though run continuously around a track. MAS can be determined by calculating the speed attained during the last successful stage of the Montreal Track Running test.
- 1200m Shuttle Test - MAS can be calculated from the total time of the test.
- Vmax - a simplified version of the VO
_{2max}test, an incremental running test on a treadmill with no gas analysis. - Yo-Yo endurance tests - a beep-type test with 5 or 10 second rest periods after each 40m run.
