A 2025 meta-analysis of 24 randomized trials in 951 older adults with sarcopenia found resistance training improved strength and function, but several gains fell below thresholds the authors used for clinical relevance.
In a commentary republished by ScienceDaily from The Conversation, Newcastle University researcher Christopher Hurst argues that strength training is central to countering sarcopenia, the age-related loss of muscle mass and strength. He cites evidence that a single weekly session may bring meaningful strength gains, particularly for newcomers. He adds that lighter weights lifted for 20 to 25 repetitions can match heavier loads when effort is high.
