I've uploaded a video of my son throwing and I need some advice. Jeremy at Windsor very kindly helped him a few months back. Over time however the lessons we learnt have slipped and he gets tremendous pain in the elbow when throwing to the point where he is about to stop altogether (again!). The video shows from behind and the side and is here: www.enriched.co.uk/javelin.aviI know the legs and feet are all wrong but you can see by the face that he was throwing under sufference so that I could video him! Is there anything obvious that anyone can see that we could work on so the elbow is not "caned" (to use his term) on each throw.

Hi nick the link won't open in Real Player. I will have a look at it for you if you can send me the file and put some thoughts on it. I will have a look at it on my quintic system I have got at home.

if you can get the DivX codex, that'll work. Using the latest winamp and that works.

Sorry I thought I'd removed the DivX codec requirement - by putting it back to WMV, but the theory fails! The free DivX Codecs are at www.divx.comI've added a Windows Media Version as well, the first version with Divx has been edited so it shows single images rather than combined images and is clearer.

Hi Nick,
Normally when the elbow hurts, it is because the javelin is being thrown "out the side", or not high enough with the shoulder of the throwing arm going past the ear.
Keeping the throwing arm high (parallel to the ground) may help.
Have been unable to see the video, but you're always welcome to come down to Eton again.

Jeremy,
I appreciate that and would love to - just didn't want to pester you too much!

Hi Nick
Few things to comment on.
He needs to be more side on to start with. His left shoulder just needs to be closed off a little more so he is looking over it.
He doesn't seem to be throwing round the side (i.e. Slinging it....where Slinger got his name), but when he strikes the jav (initially from the back) his left shoulder has dipped to the left. Keeping his left side up and accross will go some way to alleviating some elbow pain.
If you watch any video clip of top throwers from the rear view, at the moment of strike their shoulders are square. Therefore you could rest a javelin accross their shoulders and it would be parallel to the ground.
Slinger posted a photo sequence of Jan the other day of a 90m throw and this illustrates it really well.
Obviously the shoulder dips away eventually as you have to get up and over the top of your left leg (or right for the lefties amongst us).
Carry position is great so he has a great chance with this.
In terms of the legs, he needs to run with his legs out in front of him, so he never gets ahead of himself (that is.....his centre of mass, usually near the sternum, is behind his right foot during each right foot contact).
So just do some drills where he stays back, maybe x overs over 30m and film them. Compare these with his throws.
In this way he will be able to strike onto his left instead of striking over it and therefore crumpling up at the end (left leg bent). This will also help him stay up on the left as he will be striking onto a decent left and not crumpling up into a ball as he delivers the spear.
Watch some of the videos that have been posted recently and see that they are all back when their right foot hits for the final time.
Work on these two things and then he can move onto the next level and work on something else.
It is an ongoing development we are looking for so don't try to do it all at once. 2 or 3 things maximum are all a thrower can retain and as your son is obviously young we shoulden't be overloading his mind right now.
I have been there and I know exactly how it feels.
To finish, without using your legs, you will never throw the really big distances, subesequently hurting himself as he will rely on his throwing arm too much.
Hope this helps.
If you want any more advice email me. My phone number is on my email so please don't hesitate to email me. You are more likely to get me on mobile.
Cheers
David
