This condition usually appears in runners that run longer distances and are often participating in marathons or half - marathons and in the end don't receive enough
flexion in their
hips due to improper running technique and accumulated fatigue.
«If you don't get a lot of
hip flexion during the squat, you won't use your glutes.
Bryanton et al. (2012) found that peak
hip extensor moments increased with increasing depth (albeit with the same absolute loads) but Wretenberg et al. (1996) reported that peak
hip extensor moments during both powerlifting squats and during Olympic weightlifting - style squats did
not differ substantially between deep and parallel versions (deep = maximal knee
flexion vs. parallel = posterior of the hamstrings parallel to the ground).
If the range of motion for the
hips is approximately 90 degrees and in order to increase range of motion then one has to create a posterior pelvic tilt / lumbar
flexion, then wouldn't going past 90 degrees contribute to lumbar
flexion / butt wink?
Going deeper into
hip flexion with a deep squat, a pigeon pose, etc will
not do it.
We don't want to be rounded into this, we want to really use the
hip flexors to pull your
hips into
flexion and keep that lower back nice and flat.
If you don't have good control of how and when to create
flexion and extension through the
hip instead of the low back, it's really easy to end up with a super pumped up blown out low back on a workout like this.
It trains what people need most for back health and minimizes the strong
hip flexion contraction which most people aren't going to need.
Hip extension, knee extension, and ankle plantar - flexion net joint moments increased markedly as side - step distance increased, while hip abduction net joint moments did not alter much at a
Hip extension, knee extension, and ankle plantar -
flexion net joint moments increased markedly as side - step distance increased, while
hip abduction net joint moments did not alter much at a
hip abduction net joint moments did
not alter much at all.
On their own, most people compartmentalize exercise and don't see, for example, how the
hip flexion with neutral spine they develop in a deadlift is the same method they should use to pick up a heavy box or bag of dog food.
in most yoga we do less
flexion / rounding of the lower back, we do a lot of
hip hinging, lot of neutral spine in most of the poses, some extension when we do belly down back bends or bridge + as a result the lower back is
not getting its full potential rom, as we are suppose to be able to flex the lower lumbar to about 40degrees, thoracic about 45 degrees.
The
hip flexion will happen with spinal
flexion, but spinal
flexion won't happen naturally if you just do
hip flexion.
Hamstrings activity does
not appear to alter markedly with changing
hip flexion angle (Worrell et al. 2001; Mohammed et al. 2002; Guex et al. 2012).
It is unclear how the other categories should be viewed, with exercises from the
hip extension with partial knee extension,
hip extension without knee movement, and
hip extension and knee
flexion categories all appearing in the best exercises category in some but
not all studies.
However, noting the significant gain in
hip extension in the intervention group from prelunge to postlunge in the second session and comparing them to the results reported by Macdonald et al. (6) of immediate gains in knee
flexion angle post foam rolling, it is reasonable to conclude that the effects of foam rolling are immediate, even in a dynamic movement, but do
not remain for longer bouts of time.
There are also indications that injured athletes tend to display greater peak anterior pelvic tilt and peak
hip flexion on the injured side than on the uninjured side during running, while uninjured athletes do
not (Daly et al. 2015).
A variation on the sit up that only involves trunk
flexion and does
not involve
hip flexion is known as the curl up or crunch.
Thus, changes in the internal moment arm lengths of the gluteus maximus and hamstrings do
not appear to explain the greater
hip extension moment in greater degrees of
hip flexion angle.
Similarly, Fujisawa et al. (2014) found that
hip flexion angle did
not affect gluteus medius muscle activity when the knee was in full extension during isometric
hip abduction.
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.
Secondly, the hardest part of the step up is in
hip flexion (at the bottom) and the easiest part is in
hip extension (at the top), which means that gluteus maximus EMG amplitude can
not be maximized, as EMG amplitude in the gluteus maximus reduces with increasing
hip flexion (Worrell et al. 2001).
