Moreover, increases in energy absorbed
by the hip extensors (and flexors) during the swing phase have been linked to faster running speeds, suggesting that this ability to absorb energy by the biarticular hip muscles is an essential element of faster sprinting speeds (Schache et al. 2011; 2015).
Therefore, athletes sprint faster by producing more force (concentrically)
by the hip extensors (gluteus maximus, adductor magnus, and hamstrings) and hip flexors, and then absorbing it (eccentrically) by the knee flexors (hamstrings) and extensors (quadriceps).
Not exact matches
This movement will actually strengthen your whole posterior chain
by making the gluteus muscles, hamstrings and adductor magnus work together synergistically to extend the
hips, while the lower back
extensors take the role of stabilisers.
Many bodybuilders perform the glute - ham raise with their feet lower than the glute ham pad, which makes the exercise a lot easier
by taking off some of the tension placed on the
hips extensors, but if you want best results, the feet should be above the glute ham bad.
Return to the top
by contracting the quadriceps, groin and
hip extensors of the lead leg and bring the dumbbell back down under control.
One way to do this is to actively stretch them
by contracting the
hip extensor muscles.
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.
Like any joint moment, the
hip extensor joint moment is created
by the product of the muscle forces acting at the joint and their moment arm lengths.
Net work done
by the
hip (flexors in initial swing, and
extensors in terminal swing) was very strongly associated with running speed, and increased substantially with increasing speed.
For example, Masuda et al. (2005) found that ball velocity during maximal kicking efforts
by university soccer players was associated with
hip adductor but not knee
extensor torque production during isokinetic testing.
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.
Although widely used
by the general population for increasing gluteus maximus size and
by strength and conditioning coaches to enhance the strength and size of the
hip extensors to enhance sporting performance, the barbell
hip thrust exercise has not been extensively researched.
