Effects of Genetic Variation on the Efficacy of Aerobic Exercise

Participants perform high-intensity interval training (HIIT) on a cycle ergometer. The HIIT protocol consists of a 3-minute warm-up at 50W, ten 60-second high-intensity cycling intervals interspersed with 90 seconds of active recovery at 30% of their peak power output and a 2-minute cool-down at 50W for a total of 17.5 minutes.
