Even though both methods make your triceps the same size after a workout, the pause method makes the ultrasound image look more 'fuzzy' — meaning something inside the muscle changed differently.
Scientific Claim
In trained men, the 'zero point' method is associated with a larger effect size for echo intensity in the triceps brachii lateral head compared to the traditional method, despite no difference in muscle thickness, suggesting differential intramuscular changes.
Original Statement
“The Ω2 values were 0.21 (large) and 0.42 (large) for the triceps, respectively [traditional and zero point].”

Acute Effect of the “Zero Point” Method on Muscle Thickness and Muscle Damage in Trained Men
The study found that both training methods had the same effect on muscle texture (echo intensity) in the triceps, even though one used lighter weights — so the claim that one method changes the triceps more is wrong.
