Measuring Maximal Aerobic Speed (MAS)

Maximal Aerobic Speed (MAS) is a crucial factor in determining running paces for athletes in training programs. This article will provide you with an understanding of MAS and various methods used to measure it accurately.


Maximal Aerobic Speed, also known as MAS or Maximum Aerobic Speed, refers to the slowest speed at which an individual reaches their VO2max – the maximum amount of oxygen their body can utilize during intense exercise. By identifying MAS, athletes can effectively set their running paces and optimize their training routines accordingly.

Measuring MAS

MAS can be measured through a VO2max Test, which involves an incremental exercise test where the participant’s VO2max is reached as the treadmill speed continues to rise. The point at which VO2max is first achieved is recorded, providing an accurate measure of MAS. Field sport athletes generally achieve MAS values ranging from 4.4 to 4.8 m/s.

In situations where a VO2max test is not feasible, several alternative fitness tests can help estimate MAS. While these tests are not specifically designed to measure maximal aerobic running speed, they provide valuable data that can be used to calculate MAS accurately. Some of these tests include:

  • MAS run test: A maximal run over a set distance of 1.5-2km, completed within 5 to 6 minutes.
  • VAMEVAL Test: Running around a track at increasing speeds.
  • 5-minute running field test (Berthoin et al. 1997): Measuring the distance covered in 5 minutes to calculate MAS.
  • University of Montreal Track Test: The original beep test, performed continuously around a track. MAS can be determined based on the speed attained during the last successful stage.
  • 1200m Shuttle Test: Calculating MAS from the total time of the test.
  • Vmax: A simplified version of the VO2max test, involving an incremental running test on a treadmill without gas analysis.
  • Beep Test: A 20m shuttle run test with increasing pace every minute. MAS can be determined by calculating the speed attained during the last successful stage.

Q: Why is measuring MAS important for athletes?
A: Measuring MAS allows athletes to set their running paces accurately during training, helping them optimize their performance and achieve their fitness goals.

Q: Are there any alternative tests for estimating MAS if a VO2max test is not available?
A: Yes, there are several alternative tests, such as the MAS run test, VAMEVAL Test, 5-minute running field test, University of Montreal Track Test, 1200m Shuttle Test, Vmax, and Beep Test, that can provide estimates of MAS.


Maximal Aerobic Speed (MAS) plays a crucial role in determining running paces for athletes. By accurately measuring MAS, athletes can optimize their training routines and improve their overall performance. Whether through VO2max tests or alternative fitness tests, knowing MAS enables athletes to set realistic goals and track their progress effectively.
