Effects of Chronic Exercise on Hormonal and Mineral Biomarkers in Male University Students
Sponsor: High Institute of Sports and Physical Education of Kef
Summary
The purpose of this study is to investigate the effects of a high-intensity interval training (HIIT) program on hormonal and mineral biomarkers and aerobic fitness in male university students. The study aims to determine whether HIIT improves hormonal biomarkers, including testosterone, cortisol, the testosterone-to-cortisol ratio, and growth hormone (GH), as well as mineral metabolism biomarkers, including parathyroid hormone (PTH), 25-hydroxyvitamin D \[25(OH)D\], calcium, and phosphate. Participants will be assigned to either a HIIT group or a non-training control group. The HIIT group completed three sessions per week for 9 weeks, alternating 30-second runs at high-intensity and low-intensity. The control group did not participate in the training intervention and maintained its usual daily activities.

Interventions
High-intensity interval training program
The high-intensity interval training program consisted of three sessions per week for 9 weeks. Each session comprised three sets of 6-8 repetitions of 30-second running bouts performed at 100-110% of maximal aerobic speed (MAS), interspersed with 30-second active recovery runs at 50% of MAS between bouts.
