I think it’s important to distinguish the rep cadence/tempo used on FT pump sets versus just an unspecified but possibly widowmaker-esque high rep set to failure. I’m not familiar with the study you mentioned, but I would imagine that a balls out failure set with people screaming at you probably looks more like a widowmaker with the trainee pausing between reps while eking out the last few, as opposed to the constant tension no matter what FT pumps sets. The more widowmaker-like set might also have you pacing yourself and pausing/breathing between reps earlier in the set. Pump sets for legs are definitely a mental battle towards the end, but I’ve found that if you keep pumping and contracting nonstop as prescribed, that you hit failure after much fewer reps than if you were to stop even for only two seconds and then keep going for a few more. For example, on a leg press pump set I might fail on rep 25 going non-stop, whereas if I took a two second breather after rep 22 I might be able to get closer to 30.
