why do you train to not use the whole ring? im not trying to put you down by the way -- i just notice in your outdoor videos you, even as a pretty big guy, dont use the whole ring.

[jasondiscus]

Many great throwers that are bigger than me are landing the right foot near the middle of the circle. This is necessary for the conservation of rotational momentum. This momentum is very important in discus throw and I try to conserve the orbit or rotational path and maximize angular velocity. the farther you move the central axis that you rotate around in the linear direction, the harder it is to maintain angular momentum an or the energy of the discus pulling out against your axis/ body.

[jasondiscus]

This is actually my intention, but this is a very good and valid question. Here is my explanation. The whole ring need not be used until after the release for my technique.

[jasondiscus]

Sorry that my post is out of order but I meant to add that I am working for a more circular axis and not one that is ovular like I would use when I am sprinter harder towards the front. When I was using more ring, I was throwing shorter because of my ovular path which is harder to accelerate on.

dude thts a nice throw am a freshmen for eastwood high school for my meet i throw a 100 discus throw with my front end i wish i could do south african style well good job man

@jasondiscus if the angular velocity increases, will that affect the linear velocity? or is angular velocity just an increase in degrees per second and not change the linear velocity at all? Please help! i dont really know and I can't find anyone who does.

[Tmatuszak]

@jasondiscus Hey I have a question that I have been wondering for a while and it applies here. angular momentum = mass of implement x radius of orbit x angular velocity. so when any of these variables are changed, the others will change to keep the product (angular momentum) the same. so theoretically, if you shorten the radius the angular velocity will have to increase (since the mass cannot). But heres the question: ill finish it on the next post...

its so fun to watch people who are good at what they do nice throw man

[uberthrower]

thats some great analysis. the results speak for themselves! keep up the good work man, bring some discus glory back to the US!!!

@uberthrower i mean, using a shot ring kinda teaches you to only use 7 feet when youve got 8'4 to work with in reality
