Manifestations of muscle fatigue in baseball pitchers: a systematic review.

The importance of identifying fatigue in pitching is critical in injury prevention — key things to look for decreased velocity, location, and change in mechanics. The difference in mechanics may allow pitchers to go further into games and pitch more games; however, this potentially comes at the cost of increased tissue and joint loading. We need more research but for now, let's protect the young arms coming and playing baseball. Too many boys are having joint issues due to mismanaged throwing programs. Keep an eye on your pitchers.
