Dostal et al. (1986) reported that the adductor longus, adductor brevis, gracilis, obturator externus, and
pectineus displayed lengths of 0.7 cm, 0.5 cm, -0.3 cm, -0.4 cm, and 1.0 cm respectively.
The adductor magnus, adductor longus, adductor brevis and
pectineus display similar fascicle lengths, while the gracilis is much longer and the obturator externus is much shorter.
The adductor magnus, adductor longus, adductor brevis and
pectineus display lengths of around 10 — 14 cm (Friederich & Brand, 1990; Horsmann et al. 2007; Ward et al. 2009).
