Sentences with phrase «adductor magnus»

Hip extension moments are the products of the gluteus maximus, hamstrings and adductor magnus muscle forces and their associated moment arm lengths.
This may imply that hip extension movements operating at large degrees of hip flexion are more likely to require greater hamstring and adductor magnus involvement and less gluteus maximus involvement, while hip extension movements operating close to full hip extension are more likely to require greater gluteus maximus involvement.

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).
COD ability seems to be determined by the ability to decelerate quickly, which requires eccentric - specific strength of the knee extensors (quadriceps) and hip extensors (adductor magnus, gluteus maximus, and hamstrings), directed horizontally, and contracting at moderate muscle lengths.
Given the equal roles of the hip and knee extensors in this exercise, it is difficult to identify whether the effects of squat training achieves improvements in COD ability through increases in quadriceps or hip extensor (adductor magnus, gluteus maximus, and hamstrings) muscle size.
(Figure 7: Engaging the hip extensors of the raised leg (gluteus maximus, hamstrings, adductor magnus) and knee extensor (quadriceps).)

To learn how to isolate and target the lower glutes, hamstrings, and adductor magnus, stand near a wall for balance, rotate one leg far inward, and then, keeping the knee straight, lift the foot off the floor and move it back a little so its toes point toward the opposite heel.
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.
The adductor magnus is most active between 0 — 45 degrees, the adductor longus and gracilis are most active at 45 degrees, and the pectineus is most active at 90 degrees.
Garrett et al. (1984) explored the muscle fiber type of the adductor magnus.
Despite its name, the adductor magnus is actually a very important hip extensor when the hip is flexed.
You are contracting your hamstrings and adductor magnus but not your gluteus maximus.
Similarly, studies in normal healthy males using magnetic resonance imaging (MRI) scans have reported very high values for the adductor magnus of around 599.2 ± 79.4 cm ³ and much smaller values for the adductor longus (182.5 ± 18.0 cm ³) and the other adductors (from 72.0 ± 9.1 to 111.3 ± 16.6 cm ³)(Miokovic et al. 2012).
The adductor magnus originates on the ramus of the pubis, the ramus of the ischium, and the ischial tuberosity on the pelvis.
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.
This makes the hamstrings and gluteus maximus much more effective hip extensors than the adductor magnus when the hip is extended, as in the anatomical position.
The adductor magnus is a very large muscle by volume, with cadaver studies indicating that its volume in elderly people spans is around 222 ml (Friederich and Brand, 1990).
Although traditionally only deadlift and lunges are used for training the hip extensors (medial and lateral hamstrings, gluteus maximus, and adductor magnus), there is evidence that some exercises emphasize each of these muscle groups to a different extent, and also that some exercises target different regions within each of the muscles more than others.
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.
This makes the adductor magnus the most effective hip extensor in hip flexion, which corresponds to the bottom of the squat movement.
The adductor magnus displays a mixed - to - slow muscle fiber type, which may imply higher repetitions with lower loads and slower bar speeds may be beneficial.
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.
Although there is some variation between these smaller adductors, the major difference is between the adductor magnus and the other muscles, with the adductor magnus being much larger than the others.
Ignoring the adductor magnus is therefore likely to lead to a failure to maximize overall muscular hypertrophy in the lower body.
This important study provides some insight into how the different regions of three of the hip extensor muscle groups (medial and lateral hamstrings, and adductor magnus) are worked by the leg curl and the lunge.
Hip extension movements operating at large degrees of hip flexion are likely to require greater adductor magnus involvement and less gluteus maximus involvement, while hip extension movements operating close to full hip extension are more likely to require greater gluteus maximus involvement and less adductor magnus involvement.
The adductor magnus also helps you keep your thigh rolled in, with the help of other inner thigh muscles and one outer hip muscle (the gluteus medius).

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.
Whether the adductor magnus displays greater EMG activity in greater degrees of hip flexion is unclear.
The adductor magnus displays a mixed - to - slow muscle fiber type, which may imply higher repetitions with lower loads and perhaps a slower bar speed may be beneficial.
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.
This means that exercises that have peak contractions in positions of hip flexion (like full squats) likely train the adductor magnus very effectively.
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.
