No, I’m not talking about explosive isometrics. The pause is not performed in the parralell position (although, that WOULD be explosive isometrics. But it would also be the opposite of what I’m suggesting to do.) What you often see with explosive power athletes, is that some use the ‘puase’ between reps technique. In other words, you pause in the standing position AFTER the rep is completed. You pause for 3 to 5 seconds (where thigh and hip muscles get a comparative rest) and THEN you proceed with the next repetition. That is, lowering the weight back down, and pushing back again, without pauseing in the parralel position.
Muarice Green’s technique was slightly different. He would puase in the bottom position of a deep squat. But that puase at the bottom, was still a comparative rest for hips and thighs. For in the deep squat, your thighs are resting on your calves at the bottom. Hence, he would use ‘lighter’ weights. After pausing at the bottom for about 4-5 seconds (to turn of the stretch reflex) he would then explode upwards - using great neural firing to muscles to blatantly overcome inertia. (Wihout stretch reflex assistance.)
What I’m talking about however, is just the general pausing between reps (in a resting position.) The point of ‘resting’ between reps, is so that the fast twitch fibers increase their contribution to the exercises. The fast fibers take a little longer to recover, and so you some times need to pause between reps (in comparative resting position.) This has been discussed by people such as Charles Poliquin. (Who is great for science, but not so great when it comes to exercise selection for track & field athletes. His speciality is strength & hypertrophy for off-season field/team sport athletes. Also great on rehab and nutrition etc.)
