The objective of this study was to clarify the optimized lower limb motion during throwing in water polo by the simulation. The flexion/extension angles of the hip joint around the ball release were optimized in order to maximize the ball velocity. which corresponded to the hand velocity at the ball release. under the constraint in terms of the hip joint torque and power. https://parisnaturalfoodes.shop/product-category/7-3-medium-golden-blond/
