Performance analysis of golf swing using wireless inertial measurement unit sensor

Swing tempo and rhythm are the most important golf performance indicators. In this study, we investigated the swing tempo and rhythm according to different golf clubs and distance using a wireless inertial measurement unit (IMU) sensor. 14 golfers performed repeated, consistent swing with three golf clubs (driver, 7-iron, and wedge) and three distance (30m, 50m, and 70 m using wedge). The swing tempo was showed very consistently with a different golf club. The swing rhythm tends to decrease according to the golf club type with less carrying distance. Our study demonstrated that potential application of wireless IMU sensor for analyzing the golf performance parameters.
