Abstract: A method and system is provided which utilizes shear thickening fluids to enhance athletic performance. A shear thickening fluid composite is used on a golf club face to reduce the amount of side spin imparted onto a golf ball thus reducing the amount of slice or hook on the golf ball's flight path. Upon impact between the shear thickening fluid composite and the golf ball, the shear thickening fluid moves laterally away from the direction of the side spin imparted on the ball, thus reducing the amount of side spin imparted onto the golf ball. After this lateral motion, the shear thickening fluid hardens and transfers the remaining energy from the club face to the golf ball. A similar process occurs when the shear thickening fluid composite composes the outside of a golf ball. A shear thickening fluid composite is also used on an athletic shoe so as to transfer more force into a kicked ball thus having the ball travel at higher velocities.
