The relation between physical tests, measures, and clubhead speed in elite golfers

Abstract [en]

The purpose of this study was to investigate the relationship between selected physical tests and clubhead speed, and whether body mass should be considered when presenting the test results. Thirty-three male elite golfers (estimated skill range: hcp +5 to 0, age 18-30 years) participated in the study. The following test categories were measured and compared to clubhead speed with Pearson r correlation: vertical jumps (squat jump, counter movement jump, and counter movement jumps with arm swing); body mass strength (bar dips, pull-ups and vertical sit-ups); one repetition maximal strength (1-RM) (left grip, right grip and squat); and sprint (10 and 20 m). The tests and measures significantly (p < 0.05) related to clubhead speed were body mass, all vertical jumps (peak power and jump height), sprint (mean power), right grip (mass), squat (mass), bar dips (repetitions × body mass), and vertical sit-ups (repetitions × body mass). These tests may be selected when players and coaches wish to analyse physical test results associated to clubhead speed. Peak power in vertical jumps is more strongly related to clubhead speed than jump height, but jump height may be used too. In sprint, mean power should be used for feedback instead of sprint time. Strength test results should be presented in absolute values (kg), not as relative strength. Body mass should be considered in vertical jumps, sprints, and body mass strength tests, but not in 1RM strength tests with external resistance.

Abstract [en]

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.
