Even after a brutal leg workout, your muscles don’t get damaged or leak fluid in a way that shows up on ultrasound the next day.
Scientific Claim
In trained males, resistance training volume does not produce measurable muscle damage or edema as indicated by the absence of persistent changes in echo-intensity (EI) across 72 hours.
Original Statement
“Despite distinct perceptual and VL differences, no sustained muscle swelling or evidence of edema was observed, as MT and EI measurements returned to baseline within 24 hours post-session across all conditions.”

Don’t Sweat the Swelling: Exercise Volume’s Transient Effects in Trained Males
Even when trained guys did a lot of heavy squats, their muscles didn’t stay swollen or damaged — the scans showed everything went back to normal within a day.
