The Claim
In untrained adults, muscle excitation patterns measured by surface electromyography during knee extension and leg press exercises correlate with the differential hypertrophic responses observed after 12 weeks of resistance training, indicating a potential relationship between acute muscle activation and long-term muscle volume 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.
When beginners do leg exercises, the way their muscles turn on during the workout tends to match how much those muscles grow after 12 weeks — suggesting that which muscles work harder during exercise might predict which ones get bigger later.
See the scientific wording
Muscle excitation patterns measured via surface electromyography during knee extensions and leg presses in untrained adults generally mirror the differential hypertrophic responses observed after 12 weeks of training, suggesting a link between acute muscle activation and long-term volume gains.
What the research says
1 studyThe study found that which muscles worked harder during exercises like leg presses and knee extensions was the same as which muscles grew the most after 12 weeks, supporting the idea that muscle activation predicts growth.
