Hip abductor mechanics and cost comparisons in males and females.

Effective mechanical advantage (EMA), R, and hip abductor cost estimates determined at a walk (female n = 13, male n = 12) and a run (female n = 10, male n = 11) for subjects who participated in kinematics, metabolic and MRI trials. Net locomotor cost determined for a combined sample of subjects who participated in walking (female n = 19, male n = 20) and running (female n = 13, male n = 14) metabolic trials. Mean ± standard deviation. Bold values indicate statistical significance at the Holm-Bonferroni alpha level [38, 39].Hip abductor mechanics and cost comparisons in males and females.
