When people who don’t usually lift weights do strength training with or without tight bands around their limbs after exercising, they do the same amount of work—but still end up growing muscles differently. This means the muscle growth difference isn’t because one group worked harder.
Claim Language
Language Strength
definitive
Uses definitive language (causes, prevents, cures)
The claim uses 'is equivalent' and 'indicating that... are not due to'—both of which assert a definitive, causal relationship between workload equivalence and the absence of workload as a cause for muscle growth differences, leaving no room for uncertainty.

Post-exercise blood flow restriction attenuates muscle hypertrophy
The study checked what happens when you squeeze your arm after lifting weights, but the claim is about squeezing it while lifting. Even though both groups lifted the same amount, the post-lift squeeze made muscles grow less in women, so it doesn’t support the idea that volume alone explains muscle growth.
