The Technology

The Tyme Wear smart shirt measures your effort level and fatigue from breathing and biomechanics. From your breathing it determines your Aerobic and Anaerobic Thresholds as accurately as a performance lab. From the movement of your center of mass it determines your Force Production, Running Power, Ground Contact Time, and Cadence.

During endurance workouts, Tyme Wear's data tracks the wearers effort level relative to their Thresholds, their perceived level of exertion, and efficiency. As well as assessing markers of fatigue from their biomechanics.


The Smart Shirt

 How does it work?
The Tyme Wear Smart Shirt measures the speed and power at your aerobic and anaerobic thresholds during a treadmill test using breathing sensors and accelerometers embedded in the shirt. The app guides you through the test and shows you the results of your metabolic profile. The sensors in the shirt also measure your Cadence, Ground Contact Time, and Running Power.
 What is The Tyme Wear™ Performance Program?
The Tyme Wear Performance Program will help you personalize your training plan to fit your metabolic profile. Once you subscribe to the program, we'll send you a Free Smart Shirt you can wear to test your metabolic and biomechanic metrics every 4-6 weeks.
