Angiotensin converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system, and there are literature reports describing its relationship between the ACE polymorphism and muscular strength, muscular endurance and flexibility. The purpose of this study is to identify the distribution of the ACE gene polymorphism among individual golfers and the relationship between different golfers group. We analyzed the ACE gene polymorphism to study the individual differences among professional golfers (n=35), junior golfers (n=30) and general golfers (n=25). Genotype frequencies of DD, ID and II in total golfers (n=90) were 16.7%, 52.2% and 31.1% respectively. In professional golfers, the frequencies of DD, ID and II were 25.7%, 45.7% and 28.6% respectively. The frequency of DD genotype in professional golfers was higher than in junior golfers and in general golfers, but the II genotype in professional golfers was lower than in other groups. In conclusion, these data suggest that the capability and power of golf exercise are associated with the hereditary characteristics of the ACE polymorphism.

This study aims to examine the gender characteristics depending on golfers' criteria of choosing golf-wear and to identify the differences in consumption propensity. The research methodology was through the use of questionnaires, completed by golfers in Gyeongnam. As a result of examining the gender differences in the criteria of choosing golf-wear, it has been found that female golfers give more considerations to suitability to body, care convenience, and functionality than male golfers do when choosing golf-wear. As a result of analyzing the factors regarding the consumption propensity of golf-wear, they are categorized into ostentaion, fashion, aesthetic appreciation and practicality. According to the consumption propensity, male golfers were classified into three groups: ostentatious perfection, practical, common group. Female golfer were classified into three groups: practical, common, ostentatious perfection group. Groups of men golfers showed significant differences in the factors of ostentation, fashion and aesthetic appreciation of the consumption propensity. Groups of women golfers, however, showed significant differences in the factors of ostentation and practicality of the consumption propensity. It is considered that marketers need to develop golf-wear according to the gender characteristics by referring to the fact that choice criteria differ according to gender and consumption propensity.

Background: Despite frequent shoulder injuries of rotator cuff muscle of golfers by the result of overuse and poor swing mechanics, there is little research on shoulder specific rehabilitation exercises for injured rotator cuff muscle and golf swing Objective: To examined the effect of rehabilitation exercise for golfers on the X factor and ground reaction force (GRF) according to phase of the golf swing. Design: Crossover study Methods: The participants were 13 amateur golfers selected for a 4 week rehabilitation exercise for golfers. A rehabilitation exercise for golfers consisting of 5 steps and 4 items (sleeper stretch, full side plank, push up to plank, high plank knee unders) were applied to all participants. A three dimensional motion analyzer and force platform (SMART-E, BTS, Italy) were used to measure the X factor (angle between shoulder and pelvis at top of back swing) and GRF according to phase of the golf swing. All dependent variables were measured before and after exercise. The collected data was analyzed using the paired t test and SPSS 21.0. Results: The GRF had a statistically significant increase in the impact phase and ratio impact/weight after rehabilitation exercise for golfers (p<.05). The X-factor, GRF in top of back swing and finish were no significant differences between before and after exercise (p>.05). Conclusions: These results suggested that rehabilitation exercise for golfers was effective for increasing GRF in the impact phase and ratio impact/weight for amateur golfer.

This study used the questionnaire method to find out the golf factor comparison and purchase inclination according the golfers' demographic characteristics. The golf factor comparison according to the Gyeongnam golfers' demographic characteristics was performed with cross analysis and $X^2$ verification, the purchase inclination with T verification and analysis of variance. And the Golfs' factor relation according to total income was performed with cross analysis and $x^2-test$. The golfers' demographic characteristics showed a significant difference in gender, educational background and occupations. The participation purposes of playing golf for men were as a hobby, relations and business. And the participation purposes of playing golf for women were as a hobby and health. The higher age was, the more the golf career was for both men and women. In the factor of marital status, unmarried people play for a hobby and married people play for better relations and business. In the factor of gross income, male golfers varied in the gold career and monthly playing times. Female golfers varied in the golf career. Regardless of gender, the higher the income was, the more the golf career was. In the comparison of buy behavior according to the golfers' demographic characteristics, male golfers showed a significant difference in ostentation and fashion according to the monthly purchase of golf-wear. The group that spends more on the monthly purchase of golf wear was higher than the group that spends less on the monthly purchase of golf wear. Unmarried golfers showed more ostentation tendency that married golfers.

This study identified domestic and foreign golf clothing norms and extended recognition and attitude on golf clothing norms expressed in a golf wear style for golfer groups in their 20s-30s. Domestic golf clothing norms were derived from a theoretical research and case study; subsequently, golfers in their 20s-30s were classified into 4 groups. In-depth interviews were conducted using a serious leisure concept to analyze attitudes and stylistic expressions. Domestic golf clothing norms derived from stipulated and implicit norms varied as a type and situation of a golf course, gender of the golfer, and domestic golfers in their 20s-30s perceived such a point. For golfers in their 20s-30s, attitudes on golf clothing norms and their stylistic expressions showed differences according to gender and leisure type. As for gender characteristics, female golfers focused on 'look prettier' in stylistic expressions through experiences with a double-standard clothing norm; however, male golfers showed strict application and observance of a clothing norm in stylistic expressions compared to female golfers. However, male golfer groups in their 20s-30s as 'casual leisure participants' and those as 'serious leisure participants' showed differences becuase the former showed a tendency to observe clothing norms from other viewpoints and evaluations and the latter showed off their abilities and careers as a means of distinction. As for characteristic of stylistic expressions according to a leisure type, golfers in their 20s-30s showed distinction as serious leisure participants through forming new and independent clothing norms. Research findings are expected to provide an opportunity to reconsidering the influence of clothing norms in young people who have a strong tendency to express clothing style as a means to pursue individuality and taste.

The purpose of this study was to investigate the putter head movement during the putting strokes. Highly skilled 5 golfers(less than 3 handicaps) and 5 novice golfers(having no golf experience) participated in this study. A target distance was 3 m. Movements of the putter head were recorded at 60 Hz with two video cameras. The results showed that the novice golfers moved the club significantly longer than the expert golfers(p<.0001). Accoring to a movement time, novice golfers moved their club significantly faster than the expert golfers(p<0.001). Novice golfers could not control the club head effectively, and could not hit the ball correctly. Based on the impact zone movement, sweet spot of novice golfers moved faster(along the line of putt), higher(along the vertical line), and wider(along the side to side line) than that of expert golfers.

The purpose of this study was to examine the putter head movement during the putting strokes. Highly skilled 5 golfers(less than 3 handicaps) and 5 novice golfers(having no golf experience) participated in this study. A target distance was 3 m. Movements of the putter head were recorded at 60 Hz with two video cameras(1/500 shutter speed). The results showed that the angle of the clubface of expert golfers was almost 1 degree, but the novice golfers were more than 6 degrees. Expert golfers moved their hands faster than the head movement, therefore the clubface was not opened during impact. However, the novice golfers moved their hands slower than the head movement, therefore the clubface was opened during impact. The ratio of input and output angles of total movement was 1:3-4, however, the ratio of input and output angles of impact zone was 1:2. The angle of normal vector of expert golfers was less than the angle of normal vector of novice golfers.

The golf industry has become the center of attention for recreational activities in the participant sport market; however, there has been little effort made to understand golf consumer and their consumption behavior using the concept of 'recreational specialization' which segments the golfers based on level of specialization in golf. The purpose of this study was to explore the differences in the relationships among perceived service quality, price of playing golf, overall customer satisfaction with the course, and a player's intention to revisit the same golf course based on the magnitude of recreation specialization in golf. Four public and two private golf courses from the southeastern state of the United States were randomly chosen from a list in a golf magazine. The 365 surveys among 417 participants were ultimately analyzed. Multiple group analysis was conducted in order to investigate differences in relationships among service quality, price, customer satisfaction, and revisit intentions between groups based on the level of recreation specialization. The key findings were 1) for more specialized golfers, satisfaction with price did not affect overall customer satisfaction or revisit intention, however, service quality significantly influenced both overall customer satisfaction and revisit intention, 2) for less specialized golfers, satisfaction with price significantly influenced overall customer satisfaction but did not affect revisit intention. Knowledge about which the determinants of satisfaction are different between more and less specialized golfers could provide a better understanding of how different marketing strategies should be implemented for different specialized levels of golfers.
