  • Patent number: 4762320
    Abstract: An elastic wristband includes a narrow strip or patch of VELCRO material secured to the inner surface thereof. When training a right-handed athlete in propering swinging of a baseball bat, the wristband is worn on the athlete's left wrist, with the VELCRO patch positioned over and pressed against the athlete's skin covering the "leading" end of his wrist bone. The VELCRO produces a stimulation of the skin, due to relatively sharp points of the VELCRO material, This directs the athlete's attention to the location of the sensation enabling him to concentrate on that point and "aim" it as he swings the bat, thus enabling him to avoid erroneous "rolling" of his wrist during the swing before contact between the bat and a baseball. The wristband is also useful in training an athlete to maintain proper orientation of his wrist during the sequence of motions required for throwing a baseball, swinging a golf club, and during throwing of a bowling ball.
