Purpose: The purpose of this study was to analyze the immediate effects of ankle restriction with an elasticband on ground reaction force during a golf swing.Method: There were five subjects who were teaching pros with an average golf score of 75. A force platform(9281B, Switzerland) was used. The independent variable was the presence of an elastic band. The dependentvariables were three-dimensional ground reaction forces to analyze the transfer of momentum with thetiming, control and coordination of the three forces. A paired t-test within subject repeated measure designwas used via an SPSS 20.0.Results: Wearing an elastic band around one``s ankles significantly makes shorter time differences betweenthe moment of cross anterior / posterior forces and vertical force and median value of anterior / posteriorforces during the backswing, between medial and lateral maximum and anterior / posterior force from thetop of the back swing to the mid down swing, and creates an anterior / posterior maximum force.Conclusion: Wearing an elastic band around one’s ankles affects control and coordination between threedimensional forces, and anterior force power according to each phase of the golf swing.
