The Claim
In untrained adults, the rate of muscle strength and size gain during the first 5 weeks of retraining after a 10-week break is higher than the rate observed during the first 5 weeks of initial 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.
After taking a 10-week break from training, untrained adults regain muscle strength and size faster in the first 5 weeks of returning to exercise than they did when they first started training.
See the scientific wording
In untrained adults, the rate of muscle strength and size gain during the first 5 weeks of retraining after a 10-week break exceeds the rate observed during the first 5 weeks of initial training, suggesting a heightened adaptive response to re-exposure.
When muscles are trained, they add extra nuclei from satellite cells that stick around even after training stops. These extra nuclei, along with chemical tags on DNA that keep growth genes ready to turn on, let the muscle rebuild faster when training starts again, making it stronger and bigger quicker than when it was first trained.
What the research says
1 studyWhen people return to weightlifting after a 10-week break, their muscles get stronger and bigger faster in the first few weeks than when they first started — and this study proves it by comparing people who took a break to those who didn't.
