This research is aimed at suggesting more effective, objective training information to golf players through the inquiry into how much progress Korean golf has made in performance by analyzing what effect the technical factors, such as average number of hits, average number of putting, average buddy rate, par-on rate, par-save rate, recovery rate, round under par rate, and green-hitting rate revealed in the event data by the Korea Ladies Professional Gold Association(hereinafter, KLPGA) for the past 10 years from 1999 until 2008 have on performance, and also systematically analyzing what changes have been made by year through the analysis of players' performance change by factor for 10 years.
This research made regression analysis to find out the technical factors determining performance of the female professional golfers at KLPGA events and also made frequency analysis to take a look at performance change for the last 10 years[1999-2008]. In addition, the significant level of all statistical value was set up as α=.05; this research results are as follows:
1) Regression Analysis by year
(1) It was found that par break rate had the greatest effect on performance in 1999, followed by the order of buddy rate, under par rate, recovery rate, par save rate, and green-hitting rate.
(2) It was revealed that par break rate had the greatest effect on performance, followed by the order of buddy rate, under par rate, par save rate, recovery rate, and green-hitting rate in 2000.
(3) It was found out that par break rate had the greatest effect on performance, followed by the order of buddy rate, under par rate, recovery rate, par save rate, and green-hitting rate in 2001.
(4) It was revealed that buddy rate had the greatest effect on performance, followed by the order of par break rate, under par rate, par save rate, green-hitting rate, and recovery rate in 2002.
(5) It was found out that par break rate had the greatest effect on performance, followed by the order of under par rate, par save rate, buddy rate, recovery rate, and green-hitting rate in 2003.
(6) The results also show that par break rate had the greatest effect on performance, followed by the order of buddy rate, par save rate, under par rate, recovery rate, and green-hitting rate in 2004.
(7) The analysis results show that par break rate had the greatest effect on performance, followed by the order of under par rate, recovery rate, par save rate, buddy rate, and green-hitting rate in 2005.
(8) The analysis of the 2006 data shows that par break rate had the greatest effect on performance, followed by the order of buddy rate, under par rate, par save rate, green-hitting rate, and recovery rate.
(9) The 2007 data analysis indicates that buddy rate had the greatest effect on performance, followed by the order of par break rate, under par rate, par save rate, green-hitting rate, and recovery rate.
(10) The 2008 data analysis shows that under par rate had the greatest effect on performance, followed by the order of par save rate, par break rate, recovery rate, buddy rate, and green-hitting rate.
2) Integrated Regression Analysis of 10-year data
As a result of analysis of the record covering the 10 years, it was found out that under par rate had the greatest effect on performance, followed by the order of buddy rate, par save rate, par break rate, recovery rate, and green-hitting rate.
3) Frequency Analysis by 10-year ranking
As a result of analysis of six groups including a group taking the first~tenth ranking; a group taking the 11st~20th ranking; a group taking the 21st~30th ranking; a group taking the 31st~40th ranking; a group taking the 41st~50th ranking and a group staying below the 51th ranking, the number of putting, buddy rate, under par rate, green-hitting rate, par save rate, and par break rate among the factors in performance showed a noticeable difference by group, but there showed no difference in recovery rate by group, so it seems that recovery rate doesn't have any great effect on performance.
Taking a look at the influential power of technical factors affecting golfers' performance by each year on the basis of the above-mentioned research result, short game, such as par break rate or buddy rate, under par rate was found to have a great effect on performance and the factor requiring shot accuracy like green-hitting rate was found to have a less great effect on performance.
In addition, as a result of making a regression analysis by integrating all event records for the past 10 years, a short game was found to have a great effect on players' final competition results. In other words, it is considered that in golf tournaments, a stable technical strength of a short game requiring elaborateness needed in putting, approach, bunker shot, etc. are more helpful to improving performance than a long distance shot, such as driver shot, iron shot or fairway wood shot.
