Curve Sprinting

Sprinting a bend (the 200 m, relays, and most field/court running) adds a sideways force you have to manage. You lean INTO the curve from the ankles and hips — not the waist — so your body balances the centripetal force, and your inside arm and leg work differently from the outside ones.
