Abstract

Objectives To investigate the effect of sex and leg dominance on eccentric hip abduction (HABd) strength and to determine sex differences in the magnitude and direction of asymmetry. Design Cross-sectional study Setting University laboratory Participants 61 athletes (39 males, 22 females) participating in cutting sports. Main outcome measures Eccentric HABd strength was tested in both legs for all participants using an eccentric break test with a Handheld dynamometer (HHD). Results No significant differences were found between sex and adjusted HABd strength or between dominant and non-dominant legs (males: absolute; t(76) = 1.26, p= 0.158, adjusted; t(76) = 0.67, p = 0.58; females: absolute; t(42) = 1.85, p = 0.12, adjusted; t(42) = 0.83 p= 0.2). Magnitude of asymmetry was significantly significant between sexes (t(59)= 2.9, P= 0.0). Females demonstrated higher asymmetry values (15.3%) compared to males (9.8%). Direction of asymmetry was variable with Kappa coefficients showing poor levels of agreement (males =0.01, females = 0.0). Conclusion Sex differences exist in both the magnitude and direction of asymmetry for eccentric HABd strength with females showing asymmetry values of over 15% compared to 9.8% for males. As both sexes were close to the 10% threshold both sexes may benefit from HABd strengthening.
