With Kei Kamara injured, Vancouver Whitecaps counting on Anthony Blondell MLSsoccer.com Kamara suffered an adductor strain in the closing moments of training on Thursday, forcing him to miss Friday's match.
Németh and Ohlsén (1985) reported that the adductor magnus muscle moment arm length for hip extension was just 1.5 — 2.4 cm in the anatomical position, compared to 6.1 — 6.8 cm for the hamstrings, and 7.5 — 8.1 cm for the gluteus maximus, while Dostal et al. (1986) reported muscle moment arm lengths of 3.9 cm and 5.8 cm for the middle and posterior portions, respectively.
Dostal et al. (1986) reported that the adductor magnus displayed muscle moment arm lengths of -0.3 cm (i.e. external rotation) and 0.4 cm (i.e. internal rotation) for the middle and posterior portions, respectively.
However, the adductor magnus displayed a much greater moment arm length in 90 degrees of hip flexion than in full hip extension, which may indicate that this muscle has an important contributory role to hip extension moment in this position.
Moreover, as Németh et al. (1985) showed, the moment arm length does not change substantially with hip joint angle, as is observed for the other major hip extensors, the gluteus maximus and adductor magnus.
The muscle moment arms in adduction for the adductor magnus exceed those of hip extension, showing that this muscle is still definitively a hip adductor as well as a hip extensor.
The adductor magnus has a large hip extensor muscle moment arm, making it an unappreciated hip extensor, while the other adductors are hip flexors.
Dostal et al. (1986) reported muscle moment arms of -4.1 cm, -2.1 cm, and -3.6 cm for the adductor longus, adductor brevis and pectineus, respectively.
Hip extension moments are the products of the gluteus maximus, hamstrings and adductor magnus muscle forces and their associated moment arm lengths.
The adductor longus, adductor brevis, gracilis all have substantial hip adduction muscle moment arms.
The adductors have muscle moment arms at the hip that indicate roles as both hip adductors and hip extensors.
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).
Dostal et al. (1986) reported muscle moment arms of 7.1 cm, 7.6 cm, and 7.1 cm for the adductor longus, adductor brevis, and gracilis, respectively.
The adductor magnus, adductor longus, adductor brevis, gracilis all have substantial hip adduction muscle moment arms.
The moment arm length of the adductor magnus increases as hip flexion increases from full hip extension to 90 degrees of hip flexion, being largest in at least 90 degrees of hip flexion (partial squat).
Hip extension moments are created by the muscle forces of the gluteus maximus, hamstrings and adductor magnus, multiplied by their moment arm lengths.
The other hip adductor muscles similarly do not display large hip internal (or external, as denoted by negative numbers) rotation muscle moment arms in the anatomical position.
Although Pressel and Lengsfeld (1998), Arnold et al. (2000), and Arnold and Delp (2001) did not provide actual numbers for their studies, they all found that the adductors displayed very small transverse plane moment arms that are probably not meaningful.

Traditional (not force vector - specific) alternatives include trap bar deadlift jumps and jump squats, and these may also be necessary for developing the adductor magnus, which has a larger moment arm in greater hip flexion.
They reported that the hip extension moment arm length of the gluteus maximus was around 8 cm and was greater than that of the other hip extensors (adductor magnus and hamstrings).
