Watch a VO2 Max Test

This video takes you inside a real VO₂ max test, showing how sports scientists collect and analyse data while an athlete exercises at increasing intensity. You’ll see how measurements such as oxygen uptake, heart rate, breathing rate, running speed, and muscle oxygen levels change during exercise, and learn how this information is used to assess fitness and performance. The video also explains the role of the VO₂ mask and demonstrates how scientists monitor the body’s response to exercise in real time.
