Impact of high versus low fixed loads and non-linear training loads on muscle hypertrophy, strength and force development

Randomized Controlled Trial

Human

2016

The study found that lifting heavy weights to failure made people much stronger than lifting light weights to failure, even though both made muscles grow the same amount, which matches the claim exactly.
