Brief Summary

Levels of activity and physical condition among adolescents are low, increasing the risk of chronic diseases. The most recent literature suggests that physical activity and physical condition are correlated with improved biopsychosocial variables of the young. The School and, concretely, the Physical Education classes are privileged spaces, promoters of positive changes for the rest of the life. HIIT is an efficient alternative to the invested time compared to aerobic training, being a powerful stimulus in improving cardiorespiratory performance, muscles oxidative capacity and sensitivity to insulin. This study intends to verify the effectiveness and feasibility in the implementation of HIIT in High-School Physical Education classes. The activity levels and physical condition of the adolescents will be evaluated and identified, before and after 16 weeks of implementation of the training program, as well as their effects on the motivation for the practice.

HIIT Group

EXPERIMENTAL

Two HIIT sessions delivered at the beginning of Physical education classes

Other: High-Intensity Interval Training

Control Group

NO INTERVENTION

Usual programmed Physical education classes

Interventions

High-Intensity Interval Training OTHER

The program will be applied in the first 10-15 minutes of each PE class, twice a week, including a brief warm-up, ranged from 14 to 20 intervals, adopting a 2:1 work to rest ratio (ie, 30-s work, followed by 30-s rest) A cut-point of \>=90% of maximal heart rate was used as our criterion for satisfactory compliance to high-intensity exercise In order to estimate effort, fatigue and training load, a subjective effort scale will be used throughout each session. The heart rate will be monitored throughout the session in real time through Bluetooth technology. Actigraph accelerometers (wGT3X-BT), randomly distributed by the students in each session, will be used to characterize the intensity of the sessions.
