I've been pondering hips lately. Well.. turning them anyway. Watching a newer team such as the tech ladies has shown me that at least they, and maybe most newer players throw primarily with there arms. That made me think about my throws, and I find that I throw pretty much with my arms also. So I popped in my tapes from finals of old and checked out the throwers and by and large all of the good ones involved rapid twisting and not alot of arm movement at all. More arm speed. Lori went over this when she was teaching me to pull, its certainly something I wish I knew back when I would practice throwing occasionally.
Anyway back to coaching college womens. I think that the hip turn is the key to power.. and maybe the key to alot when you lack significant arm strength. The physics of throwing with your arm or your body is a similar execution, however when you're turning your body you appear smoother and gain more velocity which causes greater distance on the throws. Lori mentioned how chris o'cleary throws with a huge torso snap. Theres got to be more in this. Anyway that may be the key to jack it. I still can't do it.. but perhaps with a little throwing one afternoon I could figure it out.
