So ASMI said most pitching injuries come from poor mechanics, poor physical fitness, and overuse. Wow! It took a panel of "experts" and research grants to tell us that? Those 3 things should be painfully obvious to anyone! To protect the Brachialis and Biceps Brachii muscles from pain and injury, you need to stop using them to decelerate elbow extension. Stop the late forearm turnover that causes the forearm to fly away from the body too soon because it is trying to catch up. After turning over the forearm BEFORE front foot strike, raise the elbow up close to the ear so the elbow is pointing toward home plate. Now the Latissimus Dorsi Muscle is loaded and ready to powerfully, inwardly rotate the shoulder. Then willfully, powerfully pronate the forearm with the Pronator Teres muscle during and after release. The Pronator Teres will protect the the back of the elbow from slamming and gradually, instinctively your body will begin to shut off flexion of the Brachialis and Biceps Brachii muscles to where they will remain relaxed and will suffer no pain or injury.
The muscles in the front of the shoulder Accelerate the baseball. The muscles in the back of the shoulder decelerate the baseball. The Biceps Brachii in the front of the shoulder flexes the Shoulder joint. Stop listening to ASMI. Pass it on....in Beantown 😃
Same here. I realized I had a "pushy" arm action and that caused my bicep pain. I started using my body to throw the ball more and bicep pain is less but most of the time, no pain at all. So throw with your body not your hand.
