Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are sedentary women aged 18-25 who are not training regularly and are medically cleared for maximal exercise testing.
✕Probably not a fit
Individuals with recent injuries, neurological or sensory disorders, or medical conditions preventing maximal exercise may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Thirty sedentary women aged 18-25 will complete two testing sessions, one with a 20-meter shuttle run (aerobic) and one with a 30-second Wingate test (anaerobic). Blood samples taken before and after each protocol will measure TSH, T3, T4, and cortisol to compare acute hormonal responses between exercise modes. Exclusion criteria include recent injuries, neurological or sensory disorders, and any condition that could affect safe maximal effort. The study uses standard chemiluminescence assays for hormone measurements and will analyze differences between the aerobic and anaerobic conditions.
Why it matters
Potential benefit: If successful, the study could clarify how different exercise intensities acutely affect endocrine responses in sedentary young women.
How similar studies have gone: Previous research has examined acute hormonal responses to exercise; this study extends knowledge by directly comparing aerobic and anaerobic modalities in the same population.
