This topic came up the other day at a softball related event. I brought it to my office to dicuss with some friends as we often debate some off the wall things. None of them have DD's in softball but they are familiar with the sport and hear me talk about pitching. So maybe some knowledgeable, physics, muscle groups etc guru's can weigh in on some of the points we discussed, is it truly a natural motion.
1. All of the cave dwgs from early man and Egyptian dwgs show rocks to spear being thrown overhand. The only thing we could find thrown non overhand was the rock in a sling which seemed mostly side arm type to maybe under hand.
2. If a kid was brought up throwing with a single step stride, overhand once then underhand once, which method would produce the most velocity, the best acururcy assuming mechanics are naturally perfect in both methods. Talking about muscle groups here.
Knowing it has been discussed here before I brought up over use and how using the "it's a natural motion" theory so it won't hurt nothing. Everyone called BS. Responses ranged from walking, butt scratching, nose picking to eating as natural. There will always be pain involved as the body way of saying enough is enough if repeated too much. The body may try to offset the pain with calluses, stretched stomach etc but even natural motions have a threshold that may vary from person to person, but still a limit that can be exceeded.
Before anyone says it, yes some days are slower than others at work.
