Backhand Disc Throw


4.1 Abstract


The flight of the disc is understood but how a person produces the initial conditions


remains to be investigated. A seven segment throwing model has been developed to


investigate the kinematics and kinetics of backhand disc throws. This model specifies


the motion of the torso, allows for the motion of the glenohumeral rhythm and scapular


sliding on the thorax, and includes six degrees of freedom: three at the shoulder, and one


each at the elbow (ulnahumeral), radioulnar, and wrist (radiocarpal) joints. The equations


of motion, developed symbolically using Kane’s method, were coded in AUTOLEV.


Analysis of 57% maximal effort throws reveals that the largest power contribution results


from horizontal adduction of the shoulder providing nearly all the work done to increase


translational velocity of the disc. At release the work done by horizontal adduction


was 35 J while the total work at all joints was 34 J. The seven segments behaved as a


kinetic chain during the throw; however the elbow does not fully extend at any time. It


was flexed 57° at release, coming no closer than 27° to full extension during follow


through.

Sooo...basically you are saying practice, practice, and more practice. Beginners will not be able to keep up with the lingo. I had a a hard time keeping up and i've been playing for about eight years now. I will certainly give your advise a try though and hopfully be able to break the 500' mark consistantly.
so... how does this apply to forehand throwing again?
It doesn't.  I found somebody's thesis on the aerodynamics of disc flight and thought that this part was hilariously over-scientific so I posted it here sarcastically. 
This is the primary cause of anal seppage.
what? glenohumeral rhythm?  it does have it's dark side...

So the guy stayed loose at the joints and used a bent elbow technique while turning his hips and upper body while having his shoulder keep everything on line and chopped at the end so he wouldn't hyper extend his elbow. Sounds like what we already know, good stuff. Muwahahahahaha, a nice flat easy shot.

My interpretation of it was this:  words, words, bigger words, possible numbers, anatomy question(?), space off thinkin about Natalie Portman, words, fin.
The paralysis of analysis ;-)
Physics !
I believe that the muffler belt needs tightening.
LOL!!!
I have to start all over, dangit! I guess the person who wrote this knows best.
