Education
What is Maximum Aerobic Speed?
Maximum Aerobic Speed is the lowest running speed associated with maximal oxygen uptake. Coaches can use it to prescribe individual running speeds rather than applying the same target to an entire squad.
Different tests can produce different MAS estimates. Repeat the same testing method under similar conditions when monitoring progress.
Which test should I choose?
Yo-Yo IR1
Useful for intermittent field and court athletes because of its repeated shuttle and recovery structure.
Bronco
A simple running test requiring minimal setup and commonly used in field-sport environments.
Time Trial
Useful when a continuous track-based or straight-line running test is preferred.
How MAS can be used
Set individual running speeds
Create interval distance targets
Group athletes by capacity
Monitor changes across training blocks
