Stude DE, Gullickson J. Effects of orthotic intervention and nine holes of simulated golf on club-head velocity in experienced golfers. J Manip Physiol Ther 2000; 23(3):168-174.
Objective. To evaluate the effects of orthotic intervention on club-head velocity (CHV) among a group of experienced golfers before and after nine holes of simulated golf.
Methods. CHV was measured with a device used by many PGA and LPGA teaching professionals before and after completing nine holes of simulated golf. Subjects wore Foot Levelers custom-made, flexible orthotics daily for six weeks and then were retested with same objective measurement parameters.
Results. There was a 3-5 mph increase (7 percent) in CHV after subjects had worn Foot Levelers orthotics daily for six weeks. A 5-mph increase in CHV is equivalent to an increase in golf ball travel of 15 yards. In addition, the use of Foot Levelers orthotics eliminated the effects of fatigue associated with playing nine holes of golf and therefore may improve the likelihood for more consistent golf performance.
Discussion. In golfers, the pedal foundation has the greatest effect on lower extremity biomechanics, and thus, overall performance. A stable base of support will help generate more acceleration in the downswing, thus increasing CHV and ball flight. Improved balance leads to more consistency in contacting the ball.
Conclusion. The use of Foot Levelers’ custom-made, flexible orthotics in this study had a positive influence on increasing CHV and decreasing fatigue, both indicators of improved dynamic function.
