Summary

The purpose of this study was to investigate the effects of a high-intensity interval training (HIIT) intervention on cardiorespiratory fitness (CRF) and cardiometabolic health in active male university students. The main question it aims to answer is: Does HIIT improves CRF and cardiometabolic outcomes, including blood pressure, lipid profile, and insulin resistance estimated using the homeostasis model assessment of insulin resistance (HOMA-IR). Researchers will compare HIIT (designed to experimental group) to non-training intervention (designed to control group) to see if the training program works to improve the cardiometabolic health status. The HIIT program consisted of three sessions per week for 9 weeks, comprising of three sets of six to eight 30-second running bouts performed at 100-110% of maximal aerobic speed (MAS), interspersed with 30-second active recovery runs at 50% MAS between bouts.

High-intensity interval training (HIIT) program

The HIIT program consisted of three sessions per week for 9 weeks, comprising of three sets of sixr to eight bouts of 30-second runs at high intensity \[100-110% of maximal aerobic speed (MAS)\], interspersed with 30-second recovery runs at low intensity (50% MAS) between bouts.
