An archery bow can include a riser, a first limb coupled to the riser, a second limb coupled to the riser, a string extending between the first and second limb, and Non-Newtonian material (NN material). The NN material can be incorporated into at least one of the riser, the first limb, the second limb, the string, or another component of the archery bow. The NN material can have a material property (e.g., viscosity) which varies relative to a stress or force applied to the NN material. One or more portions of NN material can additionally, or alternatively, be incorporated into a projectile (e.g., an arrow) for an archery bow, an archery target or other archery equipment.

A system, method, and apparatus for an athlete to variably control the flexibility and stiffness parameters of a piece of athletic equipment to select a desired performance characteristic of the equipment based on the stiffness parameter. According to certain embodiments discussed herein, an item of sporting equipment may be embedded, impregnated, lined, or encased using nitinol components, wherein the nitinol components may themselves be treated using a specific method in order to achieve the desired transformation results, as described below.
