High-Intensity Interval Training and Cardiovascular Health in Teens

Abstract

Cardiovascular disease (CVD) is a growing concern globally, and the prevalence of sedentary behaviors among adolescents has contributed to increased rates of obesity, hypertension, and other risk factors. This paper explores the effects of high-intensity interval training (HIIT) on the cardiovascular health of teenagers. Evidence indicates that HIIT significantly enhances cardiorespiratory fitness markers such as VO₂ max, heart rate efficiency, and stroke volume. Additionally, HIIT contributes to favorable changes in cardiovascular disease biomarkers, including reductions in systolic and diastolic blood pressure and improvements in HDL cholesterol levels. We examine existing literature, including physiological adaptations, psychological benefits, and the implications for public health guidelines. Compared to traditional endurance training, HIIT offers comparable or superior benefits in shorter durations, making it particularly suitable for school-based physical education programs. Its adaptability, minimal equipment requirements, and engaging format support its feasibility and appeal among adolescents.This review concludes that integrating HIIT into youth fitness programs could provide a beneficial strategy for enhancing cardiovascular health among adolescents.
