Thesis (M.Tech.: Chiropractic)-Durban University of Technology, 2008. xviii, 83, [29 ], 25 leaves / Golfing literature today recommends to both the amateur and professional golfers to try and achieve maximum performance with each golf club (Seaman, 1998 and Bulbulian, Ball and Seaman, 2001). This encourages golfers to use a state of maximum spinal rotation in their golf swing in order to achieve optimal performance (Seaman, 1998), thus resulting in back pain becoming endemic in the golfing population. Thus if it is considered that performance, in terms of the golf swing, is mainly influenced by; • the strength and power of the torso, i.e. the low back and abdominal muscles (Chek, 2003), • as well as muscle balance and flexibility, i.e. those muscles which are responsible for the static and dynamic postural stability of the golf swing (Chek, 2003). It then stands to reason that any decrease in the range of motion of the lumbar or thoracic spine of the amateur golfer, in terms of biomechanics, could affect their performance (Nordin and Frankel, 2001). In this regard it is hypothesised that altered biomechanics could be that of asymptomatic segmental joint dysfunction . In terms of interventions Kirkaldy-Willis and Burton (1992) explained the effect of SMT in the treatment of low back pain, similarly Bergmann et al. (1993) and Vernon and Mrozek (2005) further proposed the following effects of spinal manipulative therapy (SMT): • SMT may stretch or break intra-articular adhesions that form from immobilised facet joints due to acute synovial reactions. • SMT allows entrapped menisci to exit the facet joint in which it became entrapped. • If the capsule of the facet gets lodged between two adjacent articular surfaces, the process of SMT could allow this to be freed. • SMT re-aligns misaligned spinal segments to conform to the centre of gravity. It was thus assumed that if these mechanical and reflex mechanisms occur in the symptomatic amateur golfer, they should also occur in the asymptomatic amateur golfer. Currently however very little is known about the effects of spinal manipulative therapy (SMT) on asymptomatic segmental joint dysfunction. Objective: Therefore, the purpose of this study was to evaluate the immediate and short term effect of spinal manipulative therapy (SMT) on asymptomatic amateur golfers in terms of performance indicators. Methods: Forty three asymptomatic participants were randomized to four equal groups consisting of ten participants each (and three drop outs). Three of the groups received a single intervention, i.e. spinal manipulative therapy (SMT) while the last group acted as a placebo control group and received no intervention. Objective measurements were taken using the EDH Sports-FlightScope Pro Electronic Swing Analyser. All objective data collection took place pre and post SMT. Statistical analysis included various statistical methods and correlation analyses, by means of the latest version of SPSS. Results and conclusions: The main findings were that certain outcomes seem to be better with lumbar manipulation alone (smash, horizontal azimuth) and others better with thoracic manipulation alone (CHV, vertical azimuth, distance), but none are better with both lumbar and thoracic manipulation. Therefore in terms of future studies of this nature the treatment groups should be analysed separately and the research powered for such analyses (e.g. larger sample sizes).

The purpose of this study was to determine if the use of a consistent pre-shot routine coupled with rehearsal imagery can increase putting performance of golfers. Two (2) volunteers participated in this study. The participants performed two putting tasks over the course of two weeks to establish baseline putting performance. Participants then met with the researcher and constructed new pre-shot routines that included positive outcome imagery. The new pre-shot routines were also presented to the participants in the form of an audio imagery CD that each participant was instructed to listen to five times a week through the remainder of the study. During the next three weeks the participants practiced their pre-shot routine and performed a putting task five times and their performance from each task was measured. With the use of visual inspection the results indicated a moderate increase in putting performance for both participants. Participants made more putts and had a smaller distance of missed putts during the treatment when compared to baseline performance. Participants did increase their pre-shot routine completion times (s). However, pre-shot routine completion times did not become more consistent from baseline to treatment. / School of Physical Education, Sport, and Exercise Science

Low, moderate, and high handicap golfers, while wearing glasses with a blinder on the side, attempted 9 putts differing in length from 5 to 21 ft under timed (less than 3.5s from grounding of club to initiation of back swing) and untimed conditions in a counterbalanced design. Confidence ratings were taken prior to and following each putt. The results revealed a significant condition by handicap group interaction (p=.021). The lower handicap group had a more consistent and lower initiation interval duration than did the moderate and high handicap players. Post interviews determined that 33 of the 35 golfers felt more comfortable in the untimed condition. However, golfers' confidence levels were not significantly different in the untimed condition as compared to the timed condition.

Two investigations were conducted with collegiate golfers for separate, but related purposes. 1) To investigate the effects of a physical conditioning program (strength, power and flexibility training) on clubhead speed, consistency, and putting distance control. 2) To investigate the effects of 36 continuous holes of competitive golf on testosterone and cortisol response and their relation to performance.Study #1: Subjects were ten men and six women NCAA Division I golfers. Supervised strength, power, and flexibility training was performed 3 times per week for 11 weeks. Golf ball launch conditions, putting distance control, strength, power, and flexibility tests were conducted before and after training. Significant (p < 0.05) increases were noted for all strength, power, and flexibility tests. Clubhead speed increased significantly (1.6%) from pre to post training, equating to a 4.9-meter increase in driving distance. No significant differences were observed for clubface-angle or launch-angle deviation. Putting distance performance significantly improved for the men-only group (29.6%). Significant (p < .05) correlations resulted between clubhead speed and rotational power (r = 0.86) for the men-only group. Qualitative video analysis did not show any consistent trends in swing mechanics alterations. Eleven weeks of physical conditioning increased clubhead speed without a negative effect on consistency or putting distance control in intercollegiate men and women golfers. Study #2: Subjects were eight NCAA Division I men golfers. Saliva samples were taken 45 minutes prior to the round and after each hole during a 36-hole competition. Time matched baseline samples were collected. Six and 36-hole area under the curve (AUC) values were calculated for endocrine measures. Salivary cortisol increased by 111% (p < 0.05) during competition compared to baseline. Testosterone-to-cortisol ratio was significantly lower (45%) throughout the competition compared to baseline. Significant (p < 0.05) correlations resulted between: 36-hole AUC testosterone-to-cortisol ratio difference and 36-hole score (r = 0.82), CSAI-2 somatic anxiety and pre-round cortisol (r = 0. 81), testosterone (r = -0.80), and testosterone-to-cortisol ratio (r = -0.72). These results indicate a significant hormonal strain during 10 hours of competitive golf, low TIC ratio relation with low golf scores, and CSAI-2 relation with endocrine measures. / School of Physical Education
