School-based HIIT and Dose-Response Effects

The project will use an intensive intermittent exercise intervention according to the high-intensity interval training programme. The programme will be implemented during physical education lessons. It involves 4 minutes of exercise in a structure of 20 seconds of intense effort and 10 seconds of rest, for a total of 8 cycles. It will be repeated twice a week (in two PE lessons) for 8 weeks. It is based on the standard physical exercises: squats, push-ups, sit-ups, toe-touches, mountain climber, jumping jacks, standing abs twist and squat to side.

However, there is a difference, comparing to the St-HIIT, related to different exercises used in protocol. This kind of HIIT programme will be based on plyometric exercises: jumping jacks, skip A, skip C, jumps back into a push-up position and returns to the squat position, throwing the legs out of support and jumping out, jumping out of a squat.
