Does Flexibility Correlate With Crunch Factor In Golf And Produce Faster Clubhead Speed?, Christopher Joyce
Christopher Joyce
Introduction: Crunch factor (CF) in golf is the product of lateral bending of the trailing side and axial rotation velocity. CF is maximised at ball impact (BI) and is thought to increase force behind the ball and increase clubhead speed. Investigations have reported dissimilar findings on CF and low back pain although, flexibility and CF have yet to be assessed. The first aim of this study was to see if flexibility (absolute range of motion – ROM) enabled golfers to maximise CF at BI for trunk and lower trunk segments. The second aim was to see if absolute ROM variables …
