Sprint Snacks: The Effects of Prolonged Rest on Reduced Exertion Interval Training.

REHIIT participants will come into the lab one time per training days (3 training days per week), each session lasting 10 minutes. Training sessions involve a two-minute warm-up, 3 X 20-second cycling sprints on an exercise bike with three minutes rest in between, and a one-minute cool-down.

"PR-REHIIT participants will come into the lab on 3 separate occasions on the training days, which occur 3 days per week (i.e., 9 sessions per week). Each session lasts 3 minutes and 20 seconds and consists of a two-minute warm-up, a 20-second all-out sprint on a cycle ergometer, and a one-minute cool-down. There will be 1-4 hours of rest in between training sessions where participants are free to leave the lab and go about their normal day."
