Other explanations include things like the hypertrophy range increasing muscle pump, improving mind-muscle connection, increasing time under tension, and among many others.
Finally because the output to the lungs is obstructed the right ventricle develops thicker muscle to push harder, resulting in right ventricular hypertrophy.
Wherever we seem to look though, the data makes it abundantly clear that there is no clear physiological hypertrophy advantage to any specific rep range.
