Abstract
The competition in elite golf is fierce. Players therefore often have psychological, physical, and technical experts supporting them. The associations between these experts focus areas and how they relate to the playing results are valuable to understand, in order to create more effective training programs. The aim of this thesis is therefore to investigate the relationships between physique, technique, and playing results in golf, and to integrate these findings with psychological research on elite golfers.
Two review studies (A and B) and three empirical studies (I, II, and III) are included. Study A and B provide a theoretical foundation where the relationship of psychological, physiological, and technical variables to playing results is reviewed. The empirical studies (Study I, II, and III) were selected based on the findings in the reviews and the applied needs.
Study I shows that some stability test results are strongly correlated to swing technique. Study II found that strength tests as measured in absolute strength or power are strongly correlated to clubhead speed for elite players, but relative strength (percentage of body mass) is not. Study III used PGA Tour ShotLink statistics collected over a year to investigate tee shot accuracy, striking distance, and hole scores. It was found that the ability to hit the ball with high accuracy and a long distance is strongly correlated with low hole scores. Furthermore, the type of fairway miss is relevant to consider as well as striking distance in relation to the distance of the hole.
These results may be used to make gap and needs profiles. Task, personal, and environmental variables should also be considered before giving training advice based on test results. Future studies should further investigate the causality between key areas and playing results, and test the validity of models that may be used to analyze and set goals for elite golfers.

I was asked to do the tests in order to evaluate them, when attending the TrackMan conference in Madrid earlier this year. I accepted as I both like to test myself and to give feedback related to technique and ball flight in order to improve golf teaching in general.

I have been teaching the D-plane for about 10 years, based upon common physics and Jorgensens book ”The physics of golf”, in several countries. I later wrote a chapter about the D-plane in the Swedish Golf Federation educational literature ”Toward lower Scores” 2006, and published a scientific article containing research about the ball flight and impact and more (Competitive Elite Golf: A Review of the Relationships between Playing Results, Technique and Physique, 2009).

This knowledge has taken far too long time to be accepted in the golf community. I believe TrackMan has helped the coaches and players greatly by measuring impact and ball flight and educating in this, for golfers, important topic. When I gave feedback on their tests, the TrackMan staff suggested that I should also send in a paper for their blog.

I then thought I should write about the next step after measuring and analyzing the ball flight and club delivery data - how to link clubhead to possible swing actions. I therefore wrote the paper B-plane and the three axis of rotation which shows the link between the clubface and the butt end of the club. When coaches fully understand where the butt should move in order to control the clubface, we can also give more objective feedback to the players.
