Abstract

INTRODUCTION
This study aimed to investigate changes in thickness of multifidus and transversus abdominis, and analyze swing mechanism and golf performance after applying spinal segmental stabilization exercise for prevention and treatment of backache targeting professional golfers.
METHOD
Subjects of this study include 6 female professional golfers belonging to KLPGA as regular members and this study conducted measurement of dependent variables before and 8 weeks after application of SSE respectively.
RESULT
As results of the foregoing, rate of change in thickness of multifidus and transversus abdominis were increased all on average. With respect to the characteristics of golf shot, there were no considerable changes in total distance and club head speed, whereas grouping radius, ball speed and smash factor were decreased on average. In the measurement this study carried out for the purpose of investigating features of the motion of golf performance, phased change of time was not shown and ground reaction force also remained without a great change.
CONCLUSION
In conclusion according to the application of SSE, First, the degree of activation of multifidus and transversus abdominis differed by individual golfers with normal muscular functions. Second, with respect to the changes in characteristics of golf shot, a positive result came out in the aspect of accuracy as grouping radius was decreased. Third, there was no significant difference in the time required for each phase of golf shot. Fourth, of the golf shot, weight movement showed no strong correlation as no great changes were shown in ground reaction force. From all these considerations, various physical factors as well as stability of spine affect golf performance ability. Further studies need to determine the relationship between local muscle activity and improved swing accuracy and statistical verification procedure targeting more golfers is considered necessary.
