Coach B, I saw this posted about Jerk Press and wanted to know what you though about what is being said. Do the statements being made apply the same to the Jerk and snatch as both are overhead movements? Thanks for any input Greg Kemp Esperanza High school I wouldn't be so quick to say that behind the neck jerks won't harm your athletes. Here are some words from Buddy Morris, former Cleveland Browns S/C coach. In my opinion, one of the best there is...definitely one of the most hard working! Here ya go: 5/5/2004 - -------------------------------------------------------------------------------- Question The other day you had posted that overhead movements like, and this is an assumption, jerk press and military were a bad thing. I was taught differently and I was wondering what the reasoning behind this idea is. I am a high school track and field and football coach...I train the shoulders using jerk press and cuff complex as auxillaries, if this is wrong, I would like to know. Thanks -------------------------------------------------------------------------------- Response: If the individuals who taught you that pressing overhead was great then ask them when was the last time they were in a cadavear lab. I understand that overhead pressing has the highest activation of all the cuff muscles but it is also the greatest irratiant and has the highest stressful forces to the shoulder joint itself. Now you should know that once you change structure, you change function. When any athlete presses overhead you take a risk and you must ask yourself is the risk worth the benefit (you should do that with any exercise you choose). ORTHOPEDICALLY speaking as the bar travels overhead you jam the head of the humerus up into the acromin, which creates impingement (as does any movement that causes the bicep to move closer to the head). Let me define shoulder impingement for all you thickheaded people out there (probably most of you are olympic based in your training knowledge and we are not creating elite weight lifters). Impingment involves a mechanical compression of the supraspinatus tendon, subacromial bursa, and the long head of the biceps tendon, all which are located under the coracoacromial arch. This compression is due to a decrease in space under said arch. Repetitive compression leads to irritation and inflammation of these structures. Shoulder impingement is also closely related to instability. Athletes who are involved in overhead ativities often exhibit hypermobility and capsular laxity. Prolonged inflammation causes decreasesd muscular efficiency and can also lend itself to one other major problem, a ruptured supraspinatus or biceps tendon. In short, shoulder impingement compresses all the soft tissue structures under the coracoacromial arch during HUMERAL ELEVATION! It also takes you out of the scapular plane and creates structural imbalances. Now ask the individuals who taught you when was the last time they were in a cadaver lab. As a strength coach you better have a working knowledge of orthopedics and rehab. I am now done trying to help people make their programs orthopedically sound, so go ahead and be old-school, which is an excuse for being DUMB!

greg....first off i am not a doc and i am not a physical therapist and no...i have not been in a cadaver lab of late. i use the push press, push jerk, power jerk, snatch pp, sn ohs, and as many overhead movements that i can. is that being dumb?? i don't think so, i have not had any injuries to the shoulder joints that was caused by overhead movements. i have had some kids with shoulder problems that bench press too much without doing the reciprocal movement patters....i.e. db pulls or bent over rows, etc. i am going to forward your note to greg glassman of crossfit. he knows way more about shoulder anatomy than i do.....i know greg believes in the overhead movements and he will more than likely contradict what is written above....coach b

This person's response makes some sense - This is a problem with poor overhead pressing/positioning, which is what is used by most people out there. active shoulders (shrugged) should eliminate the problem as I understand it.

But fundamentally what this responder says is absurd - suggesting that the human body was not intended to lift its arms overhead is DUMB.
