The Claim
Strength improvements from creatine and HMB supplementation in older adults are mediated by neuromuscular adaptations, such as enhanced motor unit recruitment, neural drive, and coordination, rather than solely by muscle hypertrophy, as indicated by regression analyses showing strength gains independent of skeletal muscle mass changes.
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.
Strength improvements from creatine and HMB supplements in older adults are due to neuromuscular adaptations like better motor unit recruitment and coordination, not just muscle growth.

Creatine and HMB supplements give muscles more energy and reduce protein breakdown. This, combined with exercise, helps the brain and nerves send stronger signals to muscles. Muscles learn to contract more efficiently, with better coordination and less interference from opposing muscles. As a result, strength increases even without adding muscle size.
What the research says
1 studyThis study gave older adults creatine and HMB supplements and found they got stronger without building bigger muscles, which backs up the idea that the supplements help the nervous system work better.
