Experimental research of impact on psychological state for adolescents with high-intensity interval training intervention

HIIT's dual mechanism-stimulating endorphin/dopamine release and enhancing physical efficacy-likely underpins its psychological benefits. The findings support HIIT as a viable school-based intervention for mitigating anxiety/depression and boosting self-esteem in adolescents. These results provide empirical groundwork for integrating HIIT into physical education curricula and mental health promotion strategies, offering a practical alternative to traditional exercise modalities.
