골프 드라이버 스윙 시 백스윙 크기에 따른 Crunch factor 비교분석

다국어 초록 (Multilingual Abstract)

The purpose of this study is to provide basic data of golf instruction to prevent back pain by comparing and analyzing a normal swing and a control swing which is shorter backswing during driver swing. In this study, we measured the size of swing, the speed of body rotation, the angle of side-bend, and the value of crunch factor of ten members of Professional Golfers" Association in their 20s by using six infrared cameras at the sampling rate of 100Hz per second.
First, the analysis on the difference in angles between forward swings and control swings revealed that forward swings were made bigger than control swings; it showed a statistically significant difference (p<.01). Second the analysis on the difference in lateral bending angles between forward swings and control swings revealed that forward swings had bigger side body angles than control swings at the points of impact (E3) and follow-through (E4) (p<.05).
Third, the analysis on the difference in crunch factors between forward swings and control swings revealed that forward swings had bigger crunch factors compared to control swings at the points of impact (E3) and follow-through (E4) (p<.05, p<.01).
In conclusion, the above results indicate that control swing makes the backswing angle small, resulting in small lateral bending angle and crunch factor. For professional golfers and instructors in the field to prevent low back pain during golf games, it is encouraged to practice control swing to make small backswings.
