H2 Physical Education: Promoting Cardiometabolic Health by 2 High Intensity Intervallic Training Protocol, Twice a Week at Physical Education

The intensive high intensity intervallic training group performs 6 sets of 60 seconds of work and 60 seconds of rest. During the first two weeks we work at an intensity of 80-85% of the reserve heart rate during the work phase and 50-55% of the reserve heart rate during the rest time. In weeks 3 and 4 the intensity in the work phase is increased by 5%, reaching from the fifth week onwards a work intensity of 95-95% of the reserve heart rate. The program duration is 8 weeks and the frequency of intervention is 2 sessions per week.
