Effects of HIIT Integrated in PE Classes, on Physical Condition, Physical Activity and Motivation for Exercise

Not Applicable

Completed

• Conditions: Adolescents
• Interventions: Other: High-Intensity Interval Training

• Registration Number: NCT04022642
• Lead Sponsor: University of Évora

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.
