Muscle fiber hypertrophy in response to 6 weeks of high-volume resistance training in trained young men is largely attributed to sarcoplasmic hypertrophy

Cohort Study

Human

2019

The study shows that after stopping training, key muscle proteins stay low for at least 8 days, which means the drop isn’t just from short-term swelling or damage.

Similar Assertions

Even if you do a lot of heavy weight training for 6 weeks, your muscle fibers don’t actually get more of the main building proteins—so the idea that your muscles grow by diluting those proteins with extra fluid probably isn’t right.
