An Abstract of Golf Putting and Postural Stability: Stance Width Influences on Static Postural Stability and Putter Kinematics Jesse David Chiero Thesis submitted in partial fulfillment of the requirements for The Masters of Science Degree in Exercise Science The University of Toledo August 2012 Objective: To examine base of support characteristics of three stance conditions, their impact on static postural stability measured by COP-Exy and their influence on the putter kinematics associated with directional control in putting. The measures were performed on skilled amateur male and female golfers. The putter kinematics of initial aim, face angle at impact, putter path through impact and impact spot were measured for all stance conditions where comparisons and associations were investigated. Design and Settings: A crossover study was performed, with randomization of each stance condition (wide, narrow, self-selected) for each subject and differences across dependent variables of directional putter kinematics, static postural stability and putt outcome were investigated. Significance was set at p<0.05. A linear regression was performed between directional putter kinematics and COP-Exy. All testing was done in an indoor golf facility, on a flat (Player’s Turf) synthetic putting surface, with the subjects using their own putter. Subjects: 18 NCAA Division I collegiate golfers (9 male, 9 female) maximum iv age range (18 – 23 years) participated in this study. Measurements: Three stance conditions were determined for each subject (self-selected, narrow, and wide). To insure consistency among trials, each stance condition was marked on a stance grid prior to testing, and twenty putting trials at each stance condition were recorded. To assess putter kinematics the SAM PuttLab ultra-sound technology was used. For static postural stability measures the Tekscan F-Scan pressure instrumentation sensor system was used. Putt outcomes (makes/misses) were also recorded to measure functional putting performance. Results: The three stance width conditions, were significantly different from one another (p=0.000) No statistically significant differences were found for the putting kinematic variables, static postural stability or putt outcome, when compared across the stance conditions. The linear regression analysis showed statistically significant, moderate positive relationships between the variables of face angle at impact (p=0.047), putter path direction (p=0.004) and impact spot (p=0.045) and the variable of total COP-Exy. Regression analysis also yielded coefficient of determination values (R Square) for impact spot of 0.115, 0.113 for face angle, 0.195 for putter path direction through impact and 0.013 for initial aim. Conclusion: the results indicated significant relationships between the magnitude of COP-Exy and face angle at impact, putter path direction and impact spot. These results indicate that positive changes in putting accuracy kinematics were associated with greater postural stability. Supporting this, the results suggest that total COP-Exy decreased as the base of support was increased, although this finding was not statisically significant. In general, the results provide only limited support for position that skilled collegiate golfers displayed biomechanically more optimal putter kinematics when using their self selected stance and had the least v biomechanically optimal putter kinematcis with a wide stance. This appears to limit the link that can be drawn between postural stability and putter kinematics.
