  • A, cross-sectional area of muscle (mm2); θ, angle between the muscle and the long axis on bone (degrees); rm, moment arm of the muscle (mm) about the joint indicated by the superscript letter (h, hip; k, knee; a, ankle); PIFE, puboishiofemoralis externus; FTI, flexor tibialis internus; FTE, flexor tibialis externus; FDL, flexor digitorum longus

  • * Measurements of pubotibialis and FTI were combined in analyses due to their close association
