Kinetic and kinematic chain theory at work!

The phenomena in exercise opens a large can of worms!  Concepts are discussed around every door, leading to a abundant controversies in the field.  Many things are unresolved as many have learned that you can make money fitting.  Many are just estimations!

The of goal of sport movement for sport sciences is achieving an optimal movement pattern (path, velocity, acceleration, angle, angular velocity, angular acceleration) for a relevant body segment. This movement structure has to be successful in connection with the anatomical, sport oriented movement.  The competitors have to move the relevant segments, and supplementary equipment on the best path.

I guess we have done our homework and so has Sue Butler who called us from back east, Sue pointed out that our teachings here in Boise, ID and over the phone allowed her to get the hole shot against some of the fastest gals in the cyclocross game.  One being last years cyclocross series winner and Wobble-naught & Myo-facts sEMG/Dartfish user Georgia Gould.  Talk about fast company! From the gun, Sue Butler (Monavie Cannondale), Gould, Compton set a blazing pace which put a big gap on the field. Sue then decided to set a pace while in third.

Back on the front, Gould and Compton traded leads, attacking each other, Georgia bobbled on a u-turn and Compton got away.  Both Georgia & Katie came up to Sue after the race to  point out how impressed they are with her new found performance.  

There are a lot of fittings systems out there today since we started the first online CAD fitting. Many have attempted to copy us, e.g.  our laser, our CAD, our Dartfish and many have fought the sEMG tooth & nail saying you can't do that.  Many don't care to use our software for one reason (Big brother putting a gun to their head) or another, mostly money, as they have to pay for our CAD and Dartfish!  And many sure don't get the results that we have! 

We don't pull the wool over your eyes with some sizing idea, rather we open them to more truths!

3. Sue Butler         (Monavie Cannondale) Wobble-naught & Myo-facts sEMG/Dartfish

Even Jeremiah Bishiop (Trek Factory) took a 2nd in the mens race!  Way to go Jeremiah!!!

This cyclocross is sure a fun event to keep your eye on.  The racing shows what you have!
Not like the team road races, where you don't know who is sand bagging!  

In the case of power oriented movements (cycling) a body segment is accelerated as result of muscular work of the athlete and get a higher and higher movement energy and impulse.  The source of this modification in movement state of different body segments, muscles and joints connected to each other is working in synergy in a well-defined order between them.

A well-done training is effective only that case, when the kinematical and dynamical parameters of the segmental movements define optimal (sometimes special) movement pattern.  Under the movement the segments are working as an interconnected chain system. 

Understanding this, it is our opinion the high velocity changes between the types of these chain system elements are the basic causes of injuries.  

Biking fitting is a complex kinematical and dynamical system and it can not be achieved by a basic mass marketing system.  There are open and closed kinematic and kinetic chains. But in real life you can define other types of chains, based on the relationships of the movement possibilities (degree of freedom, kinematic chains), and the relationships between the external and internal forces (dynamic chains).  

On this basics, we can define a new kinetic chain description system, which contains kinematical and dynamical parameters and depict the interconnections between them.

In other words, we can make you ride faster with more comfort!
Our results show that!
