Thanks Greg & Jason, I love this stuff that was the quickest 8 min video ever! I was a biomechanist and at 60 I have goals for golf. I always thought a force couple was best but I didn't know how to do it, plus I was totally ignoring the Moment arm effect to create rotation with a lateral force OH MY I have some practicing to do!! Thanks again, brilliant!
It's unclear to me what it is, exactly, that we are trying to speed up by using GRF and torque. What moving part of the swing gets the most benefit of increasing the moment arm, or increasing the force? Why does no one ever spell it out? Is it the rotation of the upper body? The hips? Is it.... at the end of a long chain reaction, simply the hands that get faster?
K I'm going to explain it, but you can just watch Dr.Kwon's video on torque, since it looks like they just copied it, and they even copied the stick figure from his research. I think that's why they don't explain it well, because they don't want it to be obvious that they got the the moment arm idea from Dr. Kwon. You shift to your right and turn in the backswing, but the turn is initiated with a push into the ground with the right foot. This gets your center of mass (approx. belly button area), moving back toward the target WHILE still rotating back. Then, as weight shifts to the left and you start to apply pressure into the ground with left foot, the horizontal force (that came from pushing the ground with the right foot) gradually turns into a vertical force - as viewed from face on. If the hozizontal force is significant enough and early enough, it will be well ahead of the center of mass, despite the fact that the center of mass has also shifted to the left. This creates a long moment arm, which allows you to increase the body's rotational speed without really increasing effort, but it happens very early in the downswing. Then, as you asked, this passes speed to the arms as the body starts to decelerate, then the hands, and ultimately the club. And you have more clubhead speed without going to the gym or really even trying to swing harder. I don't mind explaining this because I'm a Level2 Dr.Kwon instructor, and I know they are leaving all this info out of their explaination, maybe on purpose. I assume this comment will be deleted, but hopefully you can understand if you read it. Hope it helps.
@@nickcampbell8619 Thanks for taking the time and giving me this detailed answer! I'm familiar with Dr Kwon and I've seen his videos. I understand the concept of force x lever and so on, and I can also observe how the forces move through the swing. I guess I'm a bit more skeptical of the practical application of focusing on these forces when learning the swing. I'm much more in the camp of working a familiar pattern of movement (like throwing a ball) or Dr Kwons various drills with ropes and so on where people get comfortable with a single flowing motion. And even with your explanation, I'm not sure this information is more "actionable" than, let's say, simply starting by swinging a club (or rope) really slowly while paying attention to how the weight shifts and how we can accelerate the clubhead with very little effort once we learn to slow the core down and be a bit more patient in the swing and trust the mechanics. As you notice, I say: trust the mechanics (levers, forces), so I'm not discounting them, it's more a question of what to focus on.
Data driven analysis might appear to be impressive but without a true understanding of the information it does nothing for the average golfer. Everyone watching is most likely impressed but have learned nothing that will improve their swing. Basically, people like this are making a living out of confusing the $#!t out of people. Have any of you viewers learned anything that you're excited to grab a club and go outside and try right now?
This is a golf tradeshow, the PGA show, for business exhibitiors. Obviously they are showcasing Smart2move, force plate devices. The people attending this show probably understand the gist of what is happening here. For a better explanation you would need to take a lesson from someone trained to utilize and explain these devices. Dr. Greg Rose is basically an expert at analyzing golf swings to improve ground reaction forces, force and torque utilization to swing faster and hit farther. Cool stuff!

I agree
