NCT ID NCT07719296
First seen Jul 22, 2026 · Last updated Jul 24, 2026 · Updated 2 times
Summary
This trial investigates whether a 9-week high-intensity interval training (HIIT) program can improve cardiorespiratory fitness and metabolic health in healthy male university students aged 19 to 25. Participants are randomly assigned to either the HIIT group or a non-training control group. The study measures changes in blood pressure, cholesterol, triglycerides, insulin resistance, and aerobic capacity to see if HIIT offers meaningful health benefits.
