Provided is a swing speed analyzer for mounting on a swinging implement and comprising a first accelerometer, a processor and a shock attenuator. The processor uses an output from the first accelerometer to compute a swing speed of the swinging implement. The shock attenuator is comprised of a material that is sized and dimensioned to dampen an impact shock wave by more than 50% at 125 Hz. The material is preferably sized and dimensioned to dampen the impact shock wave from more than 1000 g to less than 500 g. Suitable attenuators can include viscoelastomeric materials such as foam. The swing speed analyzer can advantageously include any of a releasable attachment mechanism, a liquid crystal or other visual display, a second accelerometer, and a strain gauge. The analyzer can advantageously be attached to a golf club, a tennis racket, a baseball bat, or a hockey stick.
