Using Math to Improve Your Workout

The app will juggle the nature of the exercise, as well as the number, duration, and intensity of low- and high-intensity intervals.

Guy Thibault, exercise physiologist and adjunct professor in the School of Kinesiology and Physical Activity Sciences at the University of Montreal, is developing a web application for interval training. He calls it "the culmination of a 35-year scientific career, the challenge of a lifetime."

Existing interval training apps can come up with sessions that are physically unfeasible and make "no sense," says Thibault, who recently retired as scientific director of the Institut national du sport du Québec.

Thibault and colleagues are working to develop a more powerful and user-friendly model in which the degree of difficulty could be controlled at all times, based on the exerciser's needs. The team's graphical model incorporates all parameters of an interval training session. The final algorithm will give users full control over the level of difficulty.

"We're designing the app with high-level athletes and their coaches in mind, but it will be easy to use," Thibault says. "You won't have to have a scientific background or understand the math to appreciate its features." Release is currently scheduled for early 2023.
