Abstract:
1. A golf swing posture correction apparatus according to a movement of an anchored leg in a golf swing, the golf swing posture correction apparatus comprising: an angular speed sensor detecting rotary movement of the anchored leg in the golf swing to output a rotary movement signal; an acceleration sensor detecting one of vertical and horizontal movements of the anchored leg in the golf swing to output a linear movement signal; a control unit receiving the rotary movement and linear movement signals, and determining that the anchored leg moves if an amplitude of the rotary movement signal is greater than that of a predetermined reference signal and also if an amplitude of the linear movement signal is greater than that of the predetermined reference signal, thereby outputting a control signal; and a notification unit receiving the control signal and notifying a golfer of the movement of the anchored leg.
