The Claim
In untrained young adults, the differential hypertrophic response of the triceps surae to high-load training versus blood-flow-restricted training is not accompanied by corresponding differences in strength gains, indicating that muscle size increases do not primarily drive early strength improvements.
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 untrained young adults, muscles in the calf grow more with heavy lifting than with blood-flow-restricted training, but strength increases equally in both cases, showing that muscle growth is not the main reason for early strength gains.
See the scientific wording
In untrained young adults, the differential hypertrophic response of the triceps surae to high-load versus blood-flow-restricted training is not reflected in strength gains, indicating that muscle size increases are not the primary driver of early strength improvements.
The nervous system learns to activate more muscle fibers at the same time, making the muscle stronger even when it doesn't get bigger.
What the research says
1 studyBoth heavy lifting and light lifting with tight bands made people’s calves stronger by the same amount, but only heavy lifting made one part of the calf bigger. That means strength went up even when muscles didn’t grow much — so the body must have gotten better at using its nerves, not just growing muscle.
