I have never looked in to the mechanics of throwing , would imagine you drive of your leg and having your foot of the ground before you release would hinder rather than help.As for the rugby I would love to see England do well but cant see them winning .Maybe if we lent the Aussies our front row we could give the All Blacks a tight game?
Discus athletes don't stand in one place to throw the discus. They basically spin in a tight 540 degree circle to gain more momentum and, at the instant of the throw, they are at their fastest spinning velocity. Since spinning is like running around in tight circles, you certainly wouldn't ask why Usain Bolt's feet are off the ground when we wins the 100 m dash, would you?
