Is there any research that shows high-repetition sets increasing the capillary density in muscle?
The only thing pertaining to capillary density that I can find in literature around the PhysEd Library at the University here points to Long Slow Distance (LSD) training. 60% of VO2 max or LT for hours at a time.
The reference in the article on “100 reps to bigger muscles” talks about “endurance training” in general. Well endurance training can mean a lot of things. Muscle endurance, power endurance, anaerobic endurance, aerobic endurance; all causing different physiological changes when you train for each.
Just give me a journal entry. Anything.
