In baseball, it may appear as though pitchers' arms move in impossible ways while pitching, but this is primarily due to the extreme flexibility, strength, and skill of the pitchers, along with the high-speed nature of the motion.There are a few factors that contribute to this perception:Joint flexibility:Pitchers often have a high degree of joint flexibility, especially in their shoulders and elbows. This allows them to generate extreme rotation and extension during their pitching motion, making it seem as though their arms are bending in unusual ways.
High-speed motion:The pitching motion is very fast, often taking less than a second to complete. When we observe a pitcher's arm moving at such high speeds, it can create the illusion that their arm is bending in ways that seem physically impossible.Unique mechanics:Each pitcher has their unique pitching mechanics, which may include varying degrees of arm rotation, wrist snap, and body positioning. These individualised mechanics can contribute to the perception that a pitcher's arm is moving in impossible ways.
Slow-motion replays:When we see slow-motion replays of pitches, it can emphasise the extreme movements and rotations of a pitcher's arm, making it appear even more unusual and "impossible."
In reality, while pitchers' arms may seem to move in impossible ways, their motion is still governed by the constraints of human anatomy and bio-mechanics. It is their exceptional physical abilities, coupled with years of practice and training, that enable them to achieve such impressive and deceptive pitching motions.
