Abstract
Abstract A swinging movement in an impact sport activity, such as golf, tennis, baseball or the like, can be monitored to analyze the skill of the player by a biofeedback mechanism which measures electrical impulses created by activated nerves as muscles tense. The mechanism includes a band adapted to be placed about an arm and/or leg of the player, the band includes a pair of electrodes adapted to contact the muscle, differential amplifier means accepting the electrical voltage from the muscle, means for measuring the amplified voltage, and reporting means affording an indication of the results of the swing, such recorder including a sound emitting device, or a transmitter and computer, recording device, or printer. Preferably, the mechanism also includes a device for signalling the point of impact with an object.
