Abstract
Minimal research has been done comparing functional measures to kinematic measures in golf swings, especially for female golfers. Generally, enhanced functional movements lead to better golf performance. This study seeks to determine how bilateral hip internal (IR) and external rotation (ER) functional measures relate to the IR and ER characteristics displayed through the hips during golf swings in females. Eight right-handed female collegiate golfers had their IR and ER range of motion and power of both hips assessed. Subjects completed golf swings in front of motion capture cameras. Due to the movements made during the downswing, the Pearson correlation coefficients and significance levels were obtained for: right hip flexibility (passive IR vs. swing IR) (r = .702; p = .079), right hip power (isokinetic ER power vs. swing ER power) (r =.555, p =.153), left hip flexibility (passive ER vs. swing ER) (r = -.381, p = .351), and left hip power (isokinetic IR power vs. swing IR power) (r = .713, p = .072). None of the relationships were significant. With that in mind, strong positive relationships did exist in the right hip flexibility measures, and the left hip power measures. The lack of significant relationships suggests the golf swing is a complex motion that has many unique ways of being produced while still leading to success. A small sample size limits this study. More subjects are required to better determine if a significant relationship exists between hip rotations during the golf swing compared to flexibility and strength measures.
