What is the cost of converting rotational force (redirection) into Linear force?
I will always go with coach Newton on this when deciding on how to achieve uniform acceleration by length.
This question always never gets an answer.
Tennis players used to serve “outside of vertical” (forearm orientation) and rip their MCL’s (UCL), Flexors and Extensors until Dr. Mike Marshall showed Stan Smith how to voluntarily pronate his serves “inside of vertical”, now it’s the norm. Voluntary forearm pronation has saved many sports like football where again, Dr. Marshall taught Archie Manning, Fran Tarkenton, Brian Sipe and many more a better way for your throws to articulate by forearm pronating the QB throws over 40 years ago, now it’s the norm.
In fact all the other overhead ballistic throwing sports take advantage of driving their arms inside of vertical. Only one does both and most to the outside, that would be baseball youth, HS, College and pro pitching, the thing Dr. Marshall actually excelled at. All our youth pitchers are still taught intuitive forearm supination and have to be lucky to find the opposite information. The pros are starting to get it but they operate under a type of secret society where its hard for them to give up an advantage. Top down don’t work unless it’s recognized for what it is.
