[quote author="Matt Morsia" date="1340807121"]as a jumper, for last couple of years i’ve used quarter squats as a follow on from deep squats in the winter.
This seems to be a popular approach in jump programmes. Although not one I personally agree with. Does anyone know the origin of this approach? And what are peoples thoughts on injury risks under super heavy loads, particularly the load on the spine.[/quote]
I’ve implemented quarter squats with the protocol i’ve gotten from Seagrave. These are done for speed emphasis with quick turnaround. Typically 1sec/1sec down..timed. Begning with body weight in say…4×6 and increase weight and reps for that cycle. The weight only gets as heavy as the athlete can still maintain the 1sec up/ 1sec down.
Its funny how you can say something like Partial Squat, Quarter Squat, and everyone have a different protocol…
