Dr. Chris Ahmad Discusses Pitching Arm Injuries


Great 12:00 video from the MLB Netwiork discussing pitching arm injuries


  • Population who needs TJ the most is the 17 - 18 year olds
  • Force = Mass x Acceleration is related to the UCL ligament becoming fragile and injured so easily and frequently. The body has to be properly prepared
  • Youth pitchers are throwing with more velocity and volume than ever before
  • 2010’s there was 212 TJ surgeries
  • Velocity is the most direct link to the force on the UCL
  • Every year the average fast ball velocity increases in the MLB
  • Middle school pitchers are not tearing their UCL’s but what they do when throwing hard is they break their growth plates
  • Growth plates are weaker than UCL’s on the younger pitcher
  • Generation of force needs to start with the legs. Timing throughout the delivery has to be perfect
  • If all of the force generation is not perfect moving up through the elbow, you increase your risk for added stress in the UCL
  • Everything must be correct through the kinetic chain of the delivery to help prevent injuries especially where the pitch arm and elbow is in relation to front foot plant
  • Fatigue also increases stress in the elbow. Fatigue can follow you into your next start, throughout the season, and into your next season
  • What is also concerning is the max effort placed on every pitch thrown

Some interesting stuff to ponder



Dr. James Andrews discussing youth arm injuries @ 2:10 - 7:25 of this MLB video.



Same old incorrect Kinisioanatomical information that keeps the insanity existing.

They have made their bed but unlike good science and scientists have not learned to evolve.

The “pitch count “ believers (ASMI and all now, recognized baseball establishers) ignore the same information that all overhead throwing athletes (Tennis server’s, badminton smasher’s, Volleyball spikers, Javelin throwers, American football QB’s, Cricket bowlers and some but so few baseball pitchers) around the world understand!

In order to eliminate Ulnar Collateral Ligament (UCL) degradation is to perform an actual Kinetic chain from length that does not use the UCL as an angulative stress point. Well, how easy is that? Actually very easy and guess what it produces a faster ball and all around better command and pitch types all safely forearm driven in pronation.

Dr. Mike Marshall – “you can not start the ballistic forwards acceleration phase until the Humerus is fully outwardly rotated”

This means, do not be late with the external rotation of your shoulder (Humerus) with the simultaneous arrival of your glove side foot plant (walking response) to start the the first forwards power phase, the rotational power phase. If you are late, you then use rotational time to then get it there, wasting the rotational early phase and now loading up on the UCL. When you arrive on time the UCL acts as it should only holding bone to bone for stabilization.

The next anatomical reason for arriving on time, is the Humeral/forearm outwards rotation transition during the lengthening Kinetic chain process allows the athlete to forearm pronate all his arm drives and pitch types that has the Flexor bundle and the pronator terres contract pulling the Radius towards the Ulna, buttressing the UCL.

I’m pretty much at a loss in understanding how this info is suppressed!

For me now it is an ethical consideration that has to be applied at the youth level so parents can at least make the choice to ignore it them selves or apply it.

everyone has a pitch count. the challenging part is that the count happens to be different for everyone, so they play it safe and use a lower than average number. I believe it limits development and I believe it increases potential for injury in the higher velocity pitchers. All to preserve the arm health of the kids that really shouldn’t be pitching anyway.

The problem will always be that the only person that knows what that pitch count should be for each player, is the attentive and invested coach working with a dedicated and disciplined player. You see the issue because about .01% of coaches meet that criteria, and most kids are neither dedicated or disciplined to the level necessary to secure arm health. So… this can never be common practice. Injuries plague certain programs and are rare in others. What you need to identify is where there is a large number of highly competitive pitchers and a statistically small number of arm injuries. There you will find a coach that ‘gets it.’

No Mike Marshall pitcher will ever throw 101-106 mph. End of story.
