Higher training frequency (3 times/week vs. 2 times/week) and specific resistance types (Constant for knee extension, Combined for gait speed) are key effect modifiers for optimizing resistance training outcomes in sarcopenia.
To maximize strength gains from resistance training, aim for 3 sessions per week rather than 2. If your goal is knee strength, constant resistance machines may be best. If your goal is walking speed, a mix of resistance types (combined) might be superior. Individualize your program based on these specific goals.
Subgroup analyses revealed significant differences across resistance type, frequency, and setting... Resistance type and training frequency were key effect modifiers.
Why this rating
Based on subgroup analyses of RCTs; heterogeneity remains a concern.

- Resistance training significantly improves muscle strength and physical function in older adults with sarcopenia, but the magnitude of improvement often fails to exceed the Minimal Important Difference (MID) thresholds for clinical relevance.Moderate
- Resistance training does not significantly improve appendicular skeletal muscle mass (ASM) or appendicular skeletal muscle mass index (ASMI) in older adults with sarcopenia.Moderate
