Summary

This study looks at how many sets of weightlifting per week are best for building muscle strength and size in people aged 65 to 80. Participants will do either 6, 18, or 30 sets per week for 10 weeks. Researchers will measure changes in leg strength and muscle thickness to find the ideal weekly volume.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
resistance training (weight lifting)
What this could lead to
If successful, this study could help define the optimal amount of weekly weightlifting for older adults to maintain or improve muscle strength and size.
What could go wrong
This is a small, early-stage study with only 57 participants, so results may not apply to everyone. It is not testing a drug or treatment for a disease.
