I would partially agree! The runs you made did train your muscles that were more small and connecting the big muscle groups. In a scence you just rained the correct "small" muscles while your teammates only focused on the "big" muscle groups that everybody knows.

But it is not jsut the training, it is also the coordination and movements that are important. The more often your body is used to a certain dynamic movement and kowns how the muscles have to playe together the more resistant he is against injuries :)
