A golf club simulation apparatus includes an elongate shaft housing having opposed lower and upper ends and defining an interior area. A club head member is coupled to the lower end of the shaft housing. A battery is situated in one of the club head member and the shaft housing. An input member configured to receive club selection data is coupled to an outer surface of the shaft housing and electrically connected to the battery. A mass variability assembly is electrically connected to the input member and includes a weight member situated in the shaft housing that is selectively movable therein according to the club selection data. An electronics module having an angular sensing sensor is situated in the club head member. A bend variability assembly is included in the shaft housing for selectively altering a feel characteristic of the shaft housing during a swing motion.

A lacrosse stick for reducing the rebound of a ball caught therein. The head of the lacrosse stick has a socket for receiving the shaft, and incorporates one or a plurality of flexible elastomer pads within or as part of the handle or socket, where the head and handle meet, to damp impact and rebound. The flexibility of the damping pads produces a give that minimizes the rebound of a pocket after being impacted by a ball. This pocket dampening limits the movement of the ball and makes the ball easier to control and to retain in the pocket. The precise location of the dampening material on the lacrosse head may be varied to control the degree of pocket give in response to, for example, the force on the pocket created by a ball impacting the pocket during a catch or swinging in the pocket during cradling.
