HIIT
BehavioralA 12-week home-based HIIT exercise plan (running). Duration: Each session consists of 10 x 1-minute high-intensity bouts interspersed with 10 x 1-minute recovery periods. Adding the 3-minute warmup and 3-minute cool-down, each session totals approximately 26 minutes. This protocol is followed for 12 weeks.
Intensity: High-intensity bouts are performed at 80-90% of HRmax (RPE 15-18). Recovery periods are at 40-50% of HRmax (RPE 11-13). Warm-up and cool-down are at 50% HRmax (RPE 11-13).
Modality: Running, jogging, or brisk walking, either on a treadmill or outdoors.
Supervision: The first three sessions are supervised in a laboratory setting. Subsequent sessions are unsupervised and performed at home with heart rate monitoring and remote data tracking via Polar Flow for Coach.
