In Part 1 of this series we noted that The American Sports Medicine Institute (ASMI) suggested the top 3 primary risk factors that contribute to overuse injuries in youth baseball pitchers were:
Overbearing dad's who want their kid to get a scholarship and play pro ball???

- Total number of pitches during a game, season, and a year.
- Injuries are the result of the cumulative stress (microtraumatic trauma) of the repetitive act of throwing. This stress accumulates over multiple games, seasons and years in young players
- A statistical link has yet to be determined, however biomechanical and clinical studies are continually being reviewed to find inefficiencies in throwing mechanics that lead to increased stress on the arm
The Pitch Count Rules:

There is a small, yet vast difference in the bylaws for Little League Baseball and USA Baseball as pertaining to pitch limits and mandatory rest periods.
The Little League pitch limits are mandatory and must be strictly followed. Each league now requires a designated scorekeeper or official to track the pitch counts, and to notify umpires when pitchers reach mandatory limits. Any violation of the Little League pitch limit and mandatory rest rules may result in a forfeit.
By contrast, the USA Baseball pitch limits are recommendations. Because they are voluntary, there is no scorekeeper, and a team does not incur a penalty if the guidelines are not followed.

**However, while Little League Baseball, unlike USA Baseball, does not set mandatory limits on the number of pitches per week, it does require mandatory rest between pitching appearances. That mandatory rest effectively limits the number of pitches which can be thrown over the course of a week.
Independent Travel Baseball

A note of extreme caution to parents of youth baseball pitchers on independent travel and all-star teams competing in independently-operated tournaments: they may have NO rules at all on pitch limits and rest.
Another thing parents also need to be aware of is that if your child competes for multiple teams, it is up to you and your child to keep track of his pitch count. This is because when a child is on numerous teams, there often is little to no communication between the different coaches. With no communication, each coach only has the numbers down for his own team, not what your child did elsewhere, and not how much rest they need. Failure to keep track of this may put your child at a significant risk of an overuse injury to their elbow or shoulder that may require surgery.
Limit pitches per season and year
When it comes to a pitch count throughout the season, Little League Baseball does not set limits on that. Although USA Baseball does not either, it does have some recommendations*:

* Pitch count limits include only pitches thrown during games and don't include:
- Throws from other positions (Note: Little League bans pitchers from going behind the plate as catchers because of the amount of throwing involved in that position). The American Sports Medicine Institute seems to provide some preliminary support for that ban, finding, based on limited data, that playing catcher appeared to double or triple a pitcher's risk of injury, although the small number of injured players studied prevented a finding that the risk was significantly significant).
- Instructional pitching during practice pitching; and
- Throwing drills, which are important for developing proper mechanics - since poor throwing mechanics have been linked to increased risk of injury - and strength - since poor conditioning also increases the risk of arm injuries.
The Conditioning Of Young Pitchers
We've covered some of the important topics on the conditioning components for youth baseball players in previous posts. If they neglect the proper conditioning elements in the off-season then their chances for success and avoiding injury is limited. Proper off-season programming can be referenced here:
But what happens during the season for many young throwers? They are often told by un-informed dads and coaches that lifting weights during the season will make them "tight" or hurt their performance. This can't be further from the truth. We addressed this in a previous post. The kids are maxed out because they are playing for 2 & 3 different teams so this leaves no time to maintain their strength and mobility. They are told to go out and "run long distance" to keep their legs strong. This could possibly be the worst thing a young pitcher can do! More on these topics coming in our next post.
For our in-season guys (and softball girls) the total volume of work is reduced by 30-50% depending on a number of variables such as the athlete's training experience, physical maturity, are they a pitcher, or strictly a position player. Medicine ball work is cut in half and more emphasis is spent on countering the repetitive rotational forces that have to do with throwing and hitting. Extra attention is spent on soft tissue work, hip mobility and posterior cuff strength.
