The Claim
Exercise-induced muscle damage is not a necessary condition for muscle hypertrophy, but it may contribute to enhancing the magnitude of hypertrophic responses, although the extent and significance of this potential contribution remain uncertain.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
You don’t need to be sore after a workout to build muscle, but being sore might help you build a little more muscle—scientists aren’t sure how much, if at all.
See the scientific wording
Exercise-induced muscle damage is not essential for muscle hypertrophy, but its potential role in augmenting hypertrophic responses remains unclear.
What the research says
1 studyStudy: Stimuli and sensors that initiate skeletal muscle hypertrophy following resistance exercise.
The study says you don’t need to tear your muscles to make them bigger, but it’s not sure if getting a little sore helps you grow even more — which is exactly what the claim says.
