Why Youth Pitcher Arm Stress is (MUCH) Higher than Pro Pitchers.


Study found pitchers who can delay trunk rotation can significantly reduce stress to arm even below the level of a youth pitcher based on body weight. This proves pro pitchers do better job of timing movements than building strong shoulders to handle stress. It also proves glove side pulling can increase arm torques as it can start trunk rotation early in pitching sequence.

Why arm stress is high in youth pitchers than pro pitchers

Conventional coaching wisdom in today's game to reduce youth pitcher arm stress is to build arm strength to handle more stress & enhance their game but studies show this isn’t what is happening. Professional pitchers based on body weight actually are the best at reducing stress to the arm. This means elite pitchers get better at using more of their body to increase performance than their arm. So why are we training with extreme throwing programs like; high intent weighted baseballs, extreme long toss or run and guns? Doesn’t make any sense when you read studies like the one above.

If you think about it pro pitchers getting better at reducing arm stress as they enhance their performance makes a lot of sense. When a pitcher moves up levels of the game not only are they throwing hard but they are throwing more often with professional pitchers throwing around 200 innings a season for starters. The only way a human being can survive something so unnatural as throwing 90+mph 200 innings a year is if they are extremely talented at reducing the stress to some of the smallest joints in their body like the elbow and shoulder. Seems pretty logical to say if you want to become an elite pitcher in this game you better become a powerful and an efficient machine to survive.

Darwinism is a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others, stating that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual’s ability to compete, survive, and reproduce.

Sports are the case studies proving the Darwinian theory today. Basically the strong survive or you are only as strong as your weakest link. Problem is baseball believes the weakest link is the elbow and shoulder when actually it is always at the bottom of the kinetic chain or body. If the arm is having to take all the stress because the hips failed or the trunk went early then the problem isn’t the arm. The problem is rarely the arm when you understand how the kinetic chain or body must work together to drive energy from the ground up to the ball. In the case study above they found that the reason youth pitcher arm stress was higher than in pro pitchers was because they delayed their trunks more. This gave them more time to transfer the energy from the ground up.
