The Claim
Neural adaptations, including improved motor unit recruitment and coordination, are the primary explanation for increased muscle strength and function during weight loss without concomitant increases in muscle mass following resistance training.
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.
During weight loss, gains in muscle strength and function from resistance training occur due to improved nervous system control of muscles, not because muscles get bigger.
See the scientific wording
Neural adaptations, such as improved motor unit recruitment and coordination, likely explain improvements in muscle strength and function during weight loss without increases in muscle mass following resistance training.
When muscles are repeatedly stressed during strength exercises, sensory nerves in the muscles send stronger signals to the spinal cord and brain. This causes more nerve cells to fire at the same time and more forcefully, activating more muscle fibers. As a result, the muscle produces more force even though it does not grow larger.
What the research says
1 studyPeople who did strength exercises while losing weight got stronger without getting bigger muscles — their nerves just got better at telling their muscles when and how to work hard.
