more thoughts on olympic squats for power squats for VJ..
Power squats do allow you to lift more weight,ala why the stance and bar grip is used or preferred by powerlifting. It puts you in the best position to squat a ton of weight. Doesnt mean it puts you in the best position that corresponds to your particular goal(jumping). Also some argue less stress in certain areas(knees), allowing more long term safety.
olympic squats were in essence used by olympic lifters as a (main)assistance exercise since it isnt an actual olympic lift. The reason this makes sense is the angles of the clean(and jerk) and the correspodance to the high bar squat. Using this logic, IMO the high bar squat would offer more dynamic correspodance to the VJ. But as i stated earlier, it is not a directly corresponding exercise to the VJ, as you can easily be able to jump high or train yourself to jump high without it. Still if your sole goal is one rep VJ, or to a less degree RVJ, there is to strong correlation. Strength is general to sport, and jumping, but exercise selection still need to be based on ur specific goals.
Look, the only thing that puts you in the best position that corresponds to jumping is jumping. Squats are to develop general strength in the legs. Your legs don't give a flying fuck where the bar is sitting on your back. Your own biomechanics and the bar position will place emphasis on different muscles, but if you're worried about it, do other exercises to target the ones you don't feel are getting enough tension when you squat.* Unless you are a power lifter or an olympic lifter, it does not fucking matter one tiny little bit where the bar is in terms of transfer to whatever sport or other activity you do.
