Adductor Brevis is the smallest and shortest (hence the name brevis, meaning short in latin) of the three
short adductor muscles.
Adductor Longus is the middle of the three
short adductor muscles.
Pectineus is positioned between the Iliopsoas and Adductor Longus muscles and is part of
the short adductor group with adductors brevis and longus.
Not exact matches
Alternatively, some of the hip extensors: the hamstrings and the
adductors, are
short, stiff, and underworked.
However, increases in muscle fascicle length are also likely dependent on the mechanical load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and
adductor magnus) exercise, even when muscle length at peak contraction is
shorter (Bourne et al. 2016).
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.
There are preliminary indications that hip
adductor strengthening programs may be beneficial for reducing the incidence of
adductor - related groin strain injury (Engebretsen et al. 2008; Hölmich et al. 2010; see review by Esteve et al. 2015) and also that wearing compression
shorts may be beneficial for reducing the load on the
adductor longus during return to sport post-injury, by virtue of reducing the muscle activity during cutting actions (Chaudhari et al. 2014).
The
short head of the muscle starts between the
adductor magnus and the vastus lateralis and extends up as high as the insertion of the glute muscles.
Sprint running ability seems to be mainly determined by the ability of the hamstrings to absorb energy at long muscle lengths, and of the hip extensors (gluteus maximus,
adductor magnus, and hamstrings) and hip flexors to perform concentric work at high velocities while operating at
short muscle lengths, all in a horizontal direction.
