In contrast, the adductor longus, adductor brevis, gracilis, pectineus and
obturator externus are much smaller (Pohtilla et al. 1969; Ito et al. 2003; Ahedi et al. 2014).
On the other hand, the gracilis and
obturator externus display much smaller, less substantial muscle moment arms of -1.3 cm and -0.7 cm, respectively.
The other adductors (i.e. the adductor longus, adductor brevis, gracilis and
obturator externus) do not produce hip extension but are in fact mostly hip flexors.
The obturator externus and pectineus seem to be less important hip adductors, with muscle moment arm lengths of just 2.4 cm and 3.2 cm, respectively (Dostal et al. 1986).
In contrast, the adductor longus, adductor brevis, gracilis, pectineus and
obturator externus are much lighter.
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.
