The hamstrings are the primary target, with the gluteus maximus and adductor
magnus as the synergists and the erector spinae as the stabilizer.
Not exact matches
Rumours round the Whitehall bazaars suggest that since his elevation to a reduced role
as Foreign Secretary the great man is unlikely to finish the old
magnus opus.
The Inner Thigh also referred to
as the adductor group consists of 5 muscles — pectineus, adductor brevis, adductor longus, adductor
magnus, and gracilis.
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).
Traditionally, the adductor
magnus has been divided into two regions, an adducting region and an extending region, described variously
as posterior vs. middle (
as here), pubofemoral vs. ischiocondylar, or (true) adductor vs. «hamstring» regions.
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 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).
The adductor group comprises the adductor
magnus, adductor brevis, and adductor longus,
as well
as the gracilis and pectineus.
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.
Previously, it was known
as «tendo
magnus of Hippocrates» (van Dijk 2011).
Ito et al. 2003 found that the gluteus maximus was more than twice
as heavy
as the gluteus medius and 27 % heavier than the second heaviest muscle, the adductor
magnus.
