Check out athlete Sylvie Lloyd's breathing volume during the test: it doubles after the first two sprints.
The Running-based Anaerobic Sprint Test (RAST) measures power and fatigue with six 35m sprints at maximum pace with 10 seconds allowed between each sprint. The Hexoskin smart shirt that Sylvie is wearing measures heart rate, breathing volume, and acceleration during the test.
The metrics shown at the bottom of the screen can be monitored in real time on an iPhone or Android phone.
Hexoskin allows to measure VO2max, HRmax, HRrest, and HRrecovery too from the app.
