Talk about comments being taken out of context. Wow! That's often the problem with the written word, you have no audio cue to know the tone of the person being quoted which can change the meaning of a message significantly.
I've done a course with a "movement-tologist" for want of a better name to call him. Running is not just running and a lot of athletes in these team sports are trained to "run". The concession was that running is field sports is more than straight line or lane running, since there is change of direction or speed involved as well.
North Americans and Australians tend to take this mechanics thing across all sports so a football, hockey, basketball, player or a sprinter should all have the general mechanics of a running stride. We were shown footage of a Pakistani, a South African and a Dutch athlete and discussion about who was probably trained to run ensued. In the end the guy assured us that the Pakistani (who seemed to be the one not trained to run) was a good athlete and an effective one despite what was said about his running technique. That being said, he is of the opinion that with better training on his running technique he could be more efficient given his athletic ability.
