In 30 seconds
This systematic review evaluated the effects of testosterone therapy combined with strength training versus strength training alone in males over 60. Four randomized control trials were analyzed, revealing that testosterone administration significantly increased fat-free mass and decreased fat mass compared to strength training alone, although strength gains were not significantly different between the two groups.
Key findings
- Testosterone therapy significantly increased fat-free mass compared to strength training alone.
- Fat mass decreased more with testosterone therapy than with strength training.
- Strength gains were not significantly different between testosterone plus strength training and strength training alone.
- Functional improvements varied across studies, indicating inconsistent outcomes.
Why it matters
Understanding the impact of testosterone therapy in older males can guide clinicians in managing age-related muscle loss and functional decline. The findings highlight the potential benefits of combining hormonal treatment with exercise for improving body composition.
