Teens' hormones and mood shift after intense running program
NCT ID NCT07311460
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a 10-week high-intensity interval training (HIIT) program could affect hormones like testosterone and cortisol, as well as mental health, in healthy 14- to 16-year-old boys. Twenty-eight teens were split into a HIIT group and a non-exercise control group. The goal was to see if the intense running workouts improved fitness, hormone balance, and feelings of depression, anxiety, or stress.
