    if the accelerometer won't work...(but we won't know if we don't try)then I recall something Ben Plucknet said...he said the shot must be moving at I think it was 10 mph faster at point of release to throw 60 feet, than to throw 50 feet , furthermore , it must go double the speed to throw 70 feet over a 50 foot throw....something like 50 mph for the 70 footer ,and 25 mph for the 50 footer...what ever the speeds were doesn't matter, but I bet if we took a RADAR GUN and measured the speed during different points of the spin we would see an incredible difference between say a HS thrower and Reese Hoffas world champs throws. then just work those points for improvement of speed???? thoughts? anyone got a radar gun?

    Valenti, I am curious what you would do for a typical workout without the olympic lifts. how many times a week do you lift, etc?

    The problem with the radar gun, (as we've used it before in practice to measure the speed of our discus release), is sometimes it measures your coming out of the back, and other times it catches the release. The radar gun also takes such a long time to reload, you can't measure multiple times in a throw to see if there is continuous acceleration.

    I think it would be great feedback, even if you just cmopared technical aspects, better or worse , to the differing speeds of release. I have a cheaper radar gun that we use with my son's baseball pitching. I think I will incorperate it into my preseason data collection. Is that info Ben provided accurate? I thinks it's great feedback if we can use it.

    As linear aspects of the throw improve, force will have to increase in order to accelerate the shot. When the linear aspects of the throw decline the distance traveled by the shot increase and so less force would be needed to accelerate the shot to the same speed as the linear throw. So if the glider and the spinner both had a release velocity of 4m/s the spinner would have to only produce 89% of the gliders force in order to reach the same ending velocity. So, it takes less force in the spin than in the glide to produce the same results. However, because the spin is a more complicated movement than the glide the proper forces are harder to produce. So, keeping the spin as linear as possible like w8coach said while also increasing the distance traveled (which is a natural byproduct of the spin) helps to combine the benefits of both techniques and in turn should produce high quality shot putting.

    From what I can tell from the biomechanical studies I have read on the shot, the accelration patterns in both the glide and spin are pretty similar. In both techniques the shot never gets going much more than 2 m/s until the thrower gets to the power position. There is usually a small decleration of the shot as the thrower "settles" into the power position. Then the delivery begins. From here about 80-85% of the final release speed is generated. A 70 foot throw will be released at about 14 m/s, a 65 foot throw is generally around 13 m/s and a 60 foot throw is usually released at a little less the 12 m/s. 1 m/s is about 2.2 mph. With the rotational technique the more successful throws usually see less deceleration as the throwers enter double support before the big acceleration at the end as the extend during delivery. I think this is the portion of the throw that Reese does so well when compared to others.

    The overall distance traveled in the spin is greater than in the glide. Like Babbitt said the acceleration patterns are similar and like him I found that the shot gets going to about 2.13m/s prior to the power position and I calculated Godina's 22m Collegiate record as having a velocity of 14.40m/s on the release. Of course angle of release is going to play a role in distance but generally speaking what Babbitt posted is pretty damn close to what I have. I also think that with the spin it is easier to accomplish what Don is saying about reducing deceleration as the thrower enters double support before the delivery.
