I have nothing constructive to add.. Just that it's another great thread! Thanks boys and HUB for the kickoff! I'm learning more this fall than I've learned in years.

Fact - she's bowling righty, I mirrored the image.
Rear leg swivel(not twist) counters pelvis rotation to release upper body/arm/disc swing.
Swivel is gliding - zero torque. Twist is jamming - torque.Whats the difference between swivel and twist?
I'm trying this bowler finish, I really don't think the bowler leg thrust is what the Disc golf rear should be doing.
Swivel is effortless, smooth gliding leverage. Twist is jerking and jamming torque.Whats the difference between swivel and twist?

This video spun out of these conversations and RFrance suggested it should probably get posted in here too. Makes sense, thanks everyone for their great input.
Also created a new heavydisc post! That's unpossible!
lots of weird discussion on facebook about that video
Watch how McBeth......]
Oh fun, thankfully I quit the Facebook.
Doesn't rotate one bit on the heal, but rotates primarily flat on the foot with just a touch of toe support as he leans forward a bit. None of that "toe first, flat, then rotate on heal" bs that's been going around for ages. Hell...he even collapses his right knee a bit as he releases. If this is the wrong way to do it, I'm fine being in the wrong all this time.
1. Distance/time dropped is squared... 9.81m/s^2 is meters per second per second. Let's just round off numbers and ignore air resistance for simplicity and say your static weight is 100lbs, and gravity is 10m/s^2, so your mass is not moving distance/time, so it is about 10kg = 100lbs divided by 10m/s^1.
If you drop for 1 second, your dynamic weight becomes 1,000lbs = 10kg x 10m/s(Gravity) x 10m/s(1 Gravity second). You won't drop 1 second though, but some of the horizontal momentum also is transformed through the bracing. IIRC Markus Kallstrom was measured on a force plate to have close to 1000lbs on his front foot during the swing.
2. Absolutely, but it's a smooth rhythmic extension, not a jerk. Otherwise you would be collapsing into the ground. Just to standstill upright and static without moving around you are actively extending your leg/legs. You may even appear to be collapsing while you are actively extending or trying to extend to break your fall because gravity is always accelerating you downward and then add in that extra acceleration from falling and you have to generate even more force to maintain some semblance of upright balance.
It's the same concept/idea though. You are adding nothing to the discussion besides being a contrarian.Please stop mixing units, without some much fancier footwork lbs and kg cannot be used in the same formula like this, need to be consistent with either metric or English, lbs is a force, kg is a mass, metric equivalent of force is newton. This just hurts my head trying to follow this. Try this on for size, gravity is 10m/s/s, if you are falling for 1 s that means you are traveling at 10m/s. If we make an assumption that you stop moving in .1 s when you land your deceleration will be 10m/s/.1s or 100 m/s/s. If you weigh 10 kg and F=ma the force from falling comes out to 100m/s/s *10 kg = 1000 kg *m/s/s or 1000 Newtons. If you are standing statically, 10kg*10m/s/s (gravity)=100 kg*m/s/s or 100 newtons.
How is it BS if most people do that?
McBeth is known for collapsing his knee and being more on the toe on lower power shots, it seems to be the way he absorbs some power and gains consistency.
His rotation is through the outer part of the foot, like halfway up the foot...then his mass moves forward and he gets to the toes, yes.
IMO toe/ball pivot is just not the best way for distance or your leg. Pivoting on the ball of the foot means your heel/ankle/knee and hip all have to go airborne and end up spinning back in toward your center/weight, and your whole center is orbiting around a point, slowing down your rotational speed.Doesn't rotate one bit on the heal, but rotates primarily flat on the foot with just a touch of toe support as he leans forward a bit.
