Metabolic cost of hip abductor activation and net locomotor cost in men and women.

<p>a. Hip abductor mass-specific cost is higher in women at both a walk (<i>P</i> = 0.006) and a run (<i>P</i> = 0.006) due to lower EMA from shorter average abductor moment arm length (see text, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0118903#pone.0118903.t002" target="_blank">Table 2</a>) b. Net mass-specific locomotor cost does not differ between men and women at a walk or a run. Black bar indicates mean, box indicates mean±1SD and whiskers are mean±2SD.
