[quote=“structuredoc”]I’m still not quite following - you said the leg remains bent at a similar angle until rotation begins, but then you say the back leg bends and they continue to sit getting lower and lower as they progress toward home. If you continue to sit aren’t you changing the angle?
Couldn’t Ryan’s head move downward simply as a product of moving down the slope of the mound with his long stride?
With regard to what you want to see happen, how do you teach this to pitchers? What are the instructions/cues to make this happen?
My point about hitting was that most hitters take very little to no stride - sure there is a weight shift, but once the heel drops, almost every hitter will swing around a stationary axis - purely rotational at that point. Why not just let a pitcher do the same thing? Take little to no stride and whip the hips…[/quote]
The term sitting does not mean simply remaining the same angle, but instead the back leg being bent until point of rotation. No doubt Ryan’s head downward movement is because of the mound. But it is also because of the loading on the back leg. Next time try pushing off the rubber and video yourself, notice how your head moves down, then forward and up. The head should only go forward at least until follow through.
The hitting swing is different than a throw simply because the objective is different as well as the plane. A pitcher throws on a downward slope. I’m not suggesting throwing like how you would swing, like you said that would cause numerous problems. However, the lower body action is very similar. The objective is just different. When you swing you are trying to hit a baseball in a straight line or up. Therefore your body will remain back, but as you pitch your body comes forward as you attempt to deliver the ball as close to the plate as possible. Remember that all of this is unconscious.
Instruction is often not needed if a kid has been taught nothing. I watched a 6 year old a few days ago with perfect lower body form. He sat on his back leg until it reached his lowest point and he rotated inward.
However, sometimes kids (like me) have been taught to stride as far as possible. But what that encourages is a linear “push” not necessarily an actual push but the appearance that they are pushing off the rubber. There leg is simply pulled off the rubber as there front leg pulls them forward and then the upper body is forced to do all of the rotation leading to injury.
First thing you have to ignore stride length for a while. Length is not determined simply by how far you stretch your front leg, but by how low and how long you sit on that back leg. The longer and lower, the farther the stride. I can’t explain it well, but I will try to record myself doing a few drills the next couple days to show you how I would instruct a student of mine.
