Powerlifting may boost testosterone and improve cholesterol in athletes
NCT ID NCT07398248
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how an 8-week powerlifting program (squats, bench press, deadlifts) affects hormones, metabolism, and cholesterol in 30 male basketball players aged 18-24. Participants were randomly assigned to either powerlifting training or their usual basketball routine. Blood samples were taken before and after to measure changes in testosterone, cortisol, thyroid hormones, and other markers. The goal is to understand the physiological effects of powerlifting on athletes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Powerlifting-based training (squat, bench press, deadlift exercises)
- What this could lead to
- If successful, this study could help coaches and athletes understand how powerlifting training influences hormone levels and metabolic health, potentially improving training programs.
- What could go wrong
- This is a small, completed trial with only 30 male basketball players, so results may not apply to other groups. The study measures blood markers, not long-term health outcomes.
