Very informative and an excellent presentation of the data. It seems the GM is used sort of as you might expect, as the opposing muscle to the hip flexors. After toe-off, I've always considered the hip flexors as the accelerator for the hips driving the knee forward. It makes sense that the GM is the brakes to the knee/upper leg, and the hamstrings are the main brakes for the lower leg to get into position for the next footstrike. Note that the foot briefly hovers over the landing spot on the ground before footstrike.
Yo JP! Love your videos. I wonder if there is anything special about the mechanics of elite mountain runners like Kilian Jornet that allow them to climb steep grades faster and more efficiently?
This all makes sense. I'm a long distance runner. However, when doing sprints around a track, I often concentrate on using my gluts to hammer my leg down into the ground to propel me forward.
Given the glute is an external hip rotator it will make sure that your leg placement is in a more external rotation which is needed for a strong stable leg placement
