Wouldn't that mean the spine (head to hips) is only a component of the axis, and that hips to ground is the rest of the axis? Is the axis not a "net axis" connecting the ground to the head?
2) Lag/separation seems to be covered in the door frame drills. Door frame drill part 3 addresses the difference between the separation created by striding and settling vs. spinning (around 1:55 in the video)
3) More on the topic of sequencing and separation, what do you make of these K-Vest graphs that show the hip-shoulder separation (X-factor) happens after heel strike? Wouldn't that mean the hips opening up to create hip-shoulder separation happens after the front foot heel is down?

The rotation of the hips ,torso, and shoulders happen around the spine. Take for example the case of a spike hyzer. The player is bent way over and slanted, kind of away from his plant foot if you were looking down the spine of his back. His rotation doesnt follow a line from inbetween his shoulders going straight into his plant foot. This actually shows two planes of rotation- 1. The rotation of the hips, torso and shoulders around the spine. 2. The rotation of the body connected to the leg, which momentum causes a second pivot around the pivot point of the foot.
Now, I can certainly pivot just around the foot like an ice skater but that's not what's happening in a disc golf throw. The upper body pivots around the spine and the whole body, because of momentum, pivots on a second plane around the foot.
The problem with the door frame drill is that the motions he walks through doesn't mimic the actual disc golf throw. He shows himself leaning his weight onto his front side with his butt facing the target at that point and pulling with his arm. But that isn't what happens in a disc golf throw. In a disc golf throw the arm doesn't pull against the brace of the foot. Well, I guess it can, if you are strong arming (once again another way of showing if one is using arms or hips) the disc. In a disc golf throw, done properly, the rotation of the hips and torso whip the arm through into release. That hip and torso pull against the brace but its a completely different feeling.
The K vest graph doesn't capture the brace moment does it? How would they know? Are they using a pressure gauge under his foot to signify brace moment? As the weight transitions from rear to front there's a significant period where the foot makes first contact to when the brace actually takes place. You feel this even more as a lag in the disc golf throw. Even though there is first contact with the front leg, its not doing much of anything until the heel comes down and the weight, after that, truly shifts into brace. It's dynamic in that it takes some time until the brace actually occurs from when first contact is actually made. By the time of actual brace, the hips have already made a substantial rotation. It's at that moment that one should have maximum hip to shoulder separation. |
