The Claim
In resistance-trained individuals undergoing caloric restriction with high-volume resistance training, increases in strength are not mediated by changes in fat-free mass, and non-muscular adaptations such as neural efficiency or motor learning contribute to performance gains.
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 trained individuals who lose weight while doing high-volume resistance training, strength gains occur even when muscle mass does not increase, indicating that improvements in nervous system coordination or learning of movement patterns contribute to the strength increase.
See the scientific wording
The increase in strength during caloric restriction with high-volume resistance training in resistance-trained individuals is not explained by changes in fat-free mass, suggesting non-muscular adaptations such as neural efficiency or motor learning may contribute to performance gains.
The nervous system becomes better at activating muscle fibers more fully and coordinating them together, allowing the body to produce more force without adding muscle mass.
What the research says
1 studyWhen people on a diet lift weights a lot, they get stronger even though their muscles don’t grow bigger — this suggests their brains and nerves got better at telling their muscles how to work harder, not that they gained more muscle.
