This study examined relationships between three dimensional (3D) pelvis, hip and knee biomechanical measures in a bodyweight single leg squat and those same measures in a drop landing and a pre-planned 75° cutting manoeuvre. 40 field sports players with chronic athletic groin pain were recruited. There were no significant (p > 0.05) correlations between hip and pelvis measures in the SLS and the equivalent measures in either the drop landing or cut. This suggests that a SLS screen may not be a valid test to identify those with abnormal hip and pelvis control in aggravating activities like landing and cutting. There were, however, significant correlations (p < 0.05) between knee measures in the SLS and drop landing which may be relevant to knee injury screening.
