골프 숙련자와 비 숙련자 간시각적 거리측정 능력에 관한 연구

Abstract

The present study was conducted on 14 professional golfers and 10 amateur golfers to analyze difference of visual distance finding ability between skilled golfer and unskilled golfer and investigate the correlation between the distance finding ability and exercise capacity. Walking Counter-Professional was used for distance finding and Bushnell Pro X7 laser distance finder was also used additionally. The goal for visual distance finding was set as 45m, 55m, 60m, 80m, and 95m, and measurement was made 5 times for each goal, a total of 25 times repeatedly. As for statistical process, mean and standard deviation by subject for all scores were calculated and independent t-test was used for comparison between the groups. Finally, the following results were extracted. First, skilled golfer group showed an error distance lower by 8.77m than unskilled golfer group in visual distance finding for 45m. Second, skilled golfer group showed an error distance lower by 9.52m than unskilled golfer group in visual distance finding for 55m. Third, skilled golfer group showed an error distance lower by 7.69m than unskilled golfer group in visual distance finding for 60m. Fourth, skilled golfer group showed an error distance lower by 8.74m than unskilled golfer group in visual distance finding for 80m. Fifth, skilled golfer group showed an error distance lower by 11.81m than unskilled golfer group in visual distance finding for 95m.
