First let's look at the concept of intensity. Apparently H.I.T. views it as a feeling, like a pump, a term bodybuilders made popular. If you know a converted bodybuilder who powerlifts, he almost always lifts well under what he appears to be able to do. He has trained only the muscle, not the central nervous system. That is why smaller ball players are almost always faster and many times stronger based on percent of bodyweight.
Bodybuilders develop no reversal strength or starting or accelerating strength.
Any sport coach will tell you that acceleration is paramount in sports. Doing fewer or more lifts than Prilepin suggests will cause a decrease in training effect. Along the same parameters are the findings of Dr. Tamas Ajan and Prof. Lazar Baroga. The latter, strength endurance is basically all the H.I.T. program can possibly build. Strength endurance is characterized by a combination of great strength and significant endurance.
