A short YouTube talk by Jeff Langmaid arguing that high repetition in sport with minimal cross-training leads to strength imbalances and substantially raises injury risk. He emphasizes identifying and addressing these imbalances early (years before professional play) to reduce injuries across youth to pro levels, noting baseball pitchers are especially vulnerable due to repetitive overhead throwing.
People are playing a lot of sports, and they're playing a lot of sports a lot of times with a lot of reps, with minimal cross training, that increases the likelihood of injury. Now, it also develops that skill, don't get me wrong, but it dramatically increases the likelihood that you could be injured. So knowing at the highest level what is causing professional athletes or leading them to be more likely to injure themselves due to imbalances in strength, addressing that 10 years before, five years before, as you are coaching, training, and getting up to hopefully becoming a pro athlete, this is super, super impactful all the way down the chain and all the way up the chain from youth to professional levels and everything in between. So baseball pitchers are particularly susceptible to these types of injuries, of course, because of the repetition and the demanding nature of the overhead throwing motion.
