About you're theory of training altering kinematics, check this out:
THE INDEPENDENT EFFECTS OF GRAVITY AND INERTIA ON RUNNING MECHANICS
YOUNG-HUI CHANG, et al
[i]"Subjects ran at 110, 120 and 130 % of normal weight and mass, at 110, 120 and 130 % of normal mass while maintaining 100 % normal weight, and at 25, 50 and 75% of normal weight while maintaining 100 % normal mass.
Only relatively small changes in running kinematics were observed across the three experimental treatments. Although the force magnitudes varied for each treatment, the orientation of the vectors remained nearly constant."[/i]
Just imagine that! Actual research with a total of 9 different tests of changes in varing conditions and they were able to orientate their vector alignment without your technique training!
"[u]Similarly, a better understanding of how gravity and inertia independently influence running mechanics[/u] may provide insight into the general principles that govern legged locomotion in different habitats and across phylogenetic aquatic???terrestrial transitions (e.g. secondary aquaticism) as well as across ontogenetic aquatic???terrestrial transitions (e.g. amphibians)."
Wait a minute. Gravity and inertia influence running mechanics? That's not right. Had they studied the spatial kinematics of the runners, they would have realized that technique training would have helped make it easier for them to align their….oh, they were able to orientate vector alignment. Never mind.
You're stuck on an old paradigm, Mike. Time to move on.
So here is my question . . . This study to which you are referring, does it talk about whether the vector alignment was optimal or correct? It states, "orientate THEIR vector alignment," which basically means that they are just running the same, whether their technique is correct or not.
What i mean is this, let's say you have a triple jumper. Would you train technique with that athlete? Of course you would, because the athlete needs to learn how to properly position the limbs in order to optimize each phase. Running is no different. The force applied is a vector and if the direction of the force is misaligned, then energy is wasted and the athlete is inefficient.
This study to which you are referring seems to be saying that no matter the weight or mass of the athlete, technique wasn't changing. So take a horrible triple jumper and put him or her through the three different tests, their technique is still going to be . . . horrible, because according to the study, they would still be applying force in the same directions. They would be "orientating THEIR vector alignment" the same way each time.
