Similar Assertions

Muscle swelling induced by resistance training may persist for up to 72 hours post-exercise, potentially confounding hypertrophy measurements if assessed within this window.

Muscle swelling following resistance training returns to baseline within 24 hours, regardless of training volume (7–21 sets per session).

After a heavy leg workout, the thigh muscles get noticeably thicker due to swelling, and this lasts for at least two days.

When trained men do strength exercises, their muscles get about 13.5% bigger right after because they fill with fluid. Certain workout styles make this happen more than others.

Acute muscle swelling responses following a single resistance training session are not representative of swelling responses observed after prolonged, repeated training programs.
