The Claim
Resistance training reduces IL-1β mRNA levels in skeletal muscle, particularly in individuals classified as moderate and high responders, but this reduction is not meaningfully associated with muscle hypertrophy, suggesting that suppression of IL-1β mRNA alone does not account for differences in hypertrophic outcomes.
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.
Working out with weights can lower a specific inflammation signal in your muscles, especially in people who respond really well to exercise—but that drop in inflammation doesn’t seem to explain why some people get bigger muscles than others.
See the scientific wording
Resistance training reduces IL-1β mRNA levels in muscle, particularly in moderate and high responders, but this reduction is not meaningfully linked to muscle growth, indicating inflammation suppression alone does not explain hypertrophy differences.
What the research says
1 studyLifting weights lowered a marker of inflammation in people who grew more muscle, but that drop in inflammation didn’t explain why some people grew more muscle than others—so something else must be causing the muscle growth.
