The objective of this paper is to categorize the basic golf swing that has been covered in golf tutorials, and by identifying the interrelationships between the categories, to find the swing considered to be most ideal today. If this type of basic swing can be identified, then based on such findings, it would be possible to systematically develop the learning steps to acquire the basic swing, as well as the learning steps from the basic swing to the applied swing.

 In order to achieve this objective, concepts of the basic swing of sixty-two distinguished players were gathered from 131 distinguished golf tutorials written been from 1920 to 2001, and were categorized from a viewpoint of movement structure.

 Based on these categories, this paper has found that the concept of the basic swing can be broadly classified into four main categories. Subsequently, observations of the phylogeny of the four categories have revealed that the no wrist turn/vertical axis is the most ideal swing today.

 In future, by continuing to further categorize different variations of the basic swing considered to be ideal, and bytrying to clearly define learning objectives, it would be possible to develop a theoretically supported reasonable teaching methods, as an alternative to the methods of teaching that has depended widely on personal experience.

 The purpose of this study is to identify and explain the reasons for the golf grip that is most appropriate for the golf swing that is currently considered to be most ideal. In this study, the theories and opinions of 50 theorists studying any one of the 4 basic types of golf swings identified in the earlier study (ANDOH/ASAOKA 2003)- wrist turn/I type, wrist turn/reverse-C type, no-wrist turn/reverse-C type, no-wrist turn/I type - were researched. It was found from researching the grips advocated by the theorists, that there are 4 types of grips. The relationship between the 4 grip types and the 4 basic swing types which have transformed with technical evolvement were then researched m this study, and the grip for the swing considered to be most ideal, the no-wrist turn/I- type, was found.
 The following were made clear in this study from observations. By categorizing the grip by the V-shape made by the area between the index finger and thumb into the direction to which it points- the Jaw Direction or the Right Shoulder Direction-4 types of grips can be derived from the combination of the left / right grip with the direction to wmch the V-shape points.
 It was found that the grip which both the right and left V-shape point the Right Shoulder Direction was the most appropriate grip for the no-wrist turn/I type swing. This is due to the following reasons. With regard to the right grip, it is effective to turn the V- shape towards the right shoulder, in order not to turn the wrist. With regard to the left grip, it is effective to turn the V-shape towards the right shoulder, in order to resist the torsion of the club shaft.
 In a future study, I would like to research the posture of the address, the position and distance of the ball for a more effective coaching method for the no-wrist turn/I type swing.
