Importantly in this regard, Homan et al. (2013) found that knee valgus motion did not differ between groups with high and low hip abduction and
hip external rotation strength.
Gluteus maximus EMG amplitude can be enhanced during back extensions by performing the exercise in a position of knee flexion and / or in
hip external rotation, and by adding external loads (such as by wearing a weighted vest or holding a dumbbell or weight plate).
Gluteus maximus EMG amplitude is higher when muscle fibers are shorter (in full hip extension compared to flexion, in hip abduction compared to neutral, in
hip external rotation compared to neutral, and in posterior pelvic tilt compared to anterior pelvic tilt).
It contributes to a huge range of different joint movements, including hip extension, hip abduction,
hip external rotation, trunk extension, and posterior pelvic tilt.
So do both regions of the gluteus maximus perform hip extension, hip abduction, and
hip external rotation?
In addition, it seems likely that the gluteus maximus can also produce
hip external rotation, hip abduction (upper fibers), force closure of sacroiliac (SI) joint, force transfer through the ITB, and even force transfer through the tensor fascia latae.
This next study therefore assessed whether performing prone hip extension in a position of
hip external rotation would also alter gluteus maximus activation.
It seems that the lower glutes are only involved in hip extension, while the upper glutes are the more versatile region, performing hip extension, hip abduction, and
hip external rotation.
However, what happens when the glutes perform any of their other functions, such as hip abduction or
hip external rotation?
They found that the gluteus maximus anterior and posterior compartments both have the ability to produce substantial
hip external rotation in 0 degrees of hip flexion but the anterior compartment switches to internal rotation as the hip is flexed and the ability of the posterior compartment to perform
hip external rotation is much reduced.
In addition to hip extension, the gluteus maximus also assists other muscles in the region to produce
hip external rotation, and the upper fibers can produce hip abduction against resistance.
Consistently, it was reported that the side - lying hip abducton with
hip external rotation led to lower gluteus medius EMG activity while the side - lying hip abducton in hip internal rotation displayed greater gluteus medius EMG activity.
It is also likely that the posterior fibers assist with
hip external rotation while the anterior fibers may perform hip internal rotaton.
The posterior fibers likely also assist with
hip external rotation, while the anterior fibers may perform hip internal rotation.
Alternatively, it could imply that performing hip extension movements in greater
hip external rotation leads to greater adductor EMG amplitude performing hip extension movements in greater hip adduction does not.
They also reported that the posterior fibers have moderate
hip external rotation moment arms while the anterior fibers have large hip internal rotation moment arms.
In contrast, Pereira et al. (2010) found that hip adductor muscle activity was increased by increasing
hip external rotation angle (between 0 and 30 degrees), when using the same absolute load for each variation.
Although stance width appears to have no effect, greater
hip external rotation angles (up to 30 degrees) appear to cause increased hip adductor muscle activity.
Not exact matches
Then, you want to corkscrew your feet into the ground to enhance
hip stability and set your
hips up for optimal
external rotation torque.
Remember also that your
hips move in many directions — even though many people think of
hip - openers as
external rotation only.
● The gluteus medius is the main abductor and
external rotator of the
hip ● The gluteus maximus extends the
hip and assists with abduction and
external rotation ● The TFL is an abductor of the
hip, but because of its positioning, it can also contribute to internal
rotation
Thanks to their ability to counterbalance
external rotation of the
hip that comes from the glutes and hamstrings, they keep your knee in a more neutral position too — a benefit that's extra clutch for runners and cyclists alike.
You need these muscles for

Yes, it is an

To emphasize both the

It pulls the

Keep your toes pointing either forward or back to avoid opening the

So, I'll have people start with a shinbox position, which lets you work internal and
external rotation of the
hip at same time.
The most common compensations seen in those with a
hip internal
rotation deficit (HIRD) include overpronation at the feet, a knee valgus, reduced step length,
external rotation of the foot toward terminal stance phase and increased lumbar and knee extension.
Gluteus maximus: Responsible for
hip extension and
external rotation.
Since many yoga poses that stretch the deep
external rotators are called «
hip openers», can I assume that the yoga community is talking about
external rotation when they are talking about «

Fantastic exercise for coordinating your ability to rotate the

The thing is that

hip opening.»
For example, Yoo (2014) specifically discussed using exercises to target separate regions within the gluteus medius and it is thought that Fredericson et al. (2000) also employed a protocol involving the side - lying
hip abduction with
external rotation in order to preferentially recruit the posterior segment of the gluteus medius.
These figures indicate that the hamstrings are not particularly active in
hip internal or
external rotation (negative numbers) in the anatomical position.
The answer is yes, and the method has three parts: Selectively contract those parts of the gluteus maximus that produce the most
hip extension with the least abduction and
external rotation, contract helper muscles that add to the
hip extension, and contract guiding muscles that can help hold the thighbones in.
