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.

10. A method for monitoring coordination of muscular activity of a player during a swinging movement during an impact sport activity to monitor the player'"'"'s skill, said method comprising the steps of
placing a pair of electrodes over a muscle to be monitored during the activity, continuously measuring the electrical field emitted by the nerves communicating with the muscle, amplifying the voltage to provide an electrical signal, reporting the magnitude of said electrical signal to a recording device, and sensing the point of impact during the swinging movement with an object and directing a signal to said recording device.
- 15. A method for monitoring coordination of muscular activity during movement through a golf swing, said method comprising continuously measuring the electrical field emitted by the nerves communicating with a first muscle and reporting the magnitude of said first electrical signal as a reference point, wherein said first electrical signal is amplified, said amplified signal is transmitted to a remote location and the signal is converted at the remote location to perceivable signal, said transmission being by radio signal, continuously measuring the electrical field emitted by the nerves communicating with a second muscle and reporting the magnitude of said electrical signal to determine coordination of said second muscle with said first muscle, wherein said second measurement is amplified and transmitted to a remote location by radio signal, said radio signal being converted to a perceivable signal and reporting the first and second perceivable signals in conjunction with each other to display the degree of coordination of the two muscles.
