This post comes from our colleague, Graeme Lehman, in Kelowna, BC. Graeme has a great blog which you can find at lehmansbaseball.wordpress.com. If you are from the area, make sure you see Graeme.
Quick recap of Part 1 since I wrote it 3+ months ago. This article talked about a study which reported that pitchers who threw with excessive contralateral tilt could produce more velocity than those who didn’t tilt as much. This extra velocity came with a price which was more joint forces at the elbow and shoulder which could lead to an injury. The amount that each pitcher tilt’s is going to dictate which arm slot they use since the arm should always be at 90-100 degree angle from the trunk in order to maximize force and minimize injuries.
