The Claim
Home-based progressive resistance training performed three times per week for 12 weeks significantly improves handgrip strength and sit-to-stand performance in dynapenic older adults with low protein intake, with large effect sizes, despite no measurable increase in muscle mass, indicating that strength gains are driven by neuromuscular adaptations rather than hypertrophy.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older adults with muscle weakness and low protein intake, a 12-week home-based resistance training program performed three times per week increases handgrip strength and sit-to-stand ability without increasing muscle size, showing that the strength gains result from improved nerve-to-muscle communication.

The nerves controlling the muscles become better at signaling them to contract harder and more efficiently, making the muscles produce more force without getting bigger.
What the research says
1 studyOlder adults with weak muscles who did strength exercises at home three times a week for three months got stronger at gripping and standing up—even though their muscles didn’t get bigger. This means their nerves got better at telling their muscles when to work, not their muscles growing larger.
