REG wrote:Wait, I just re-read Kurz's Stretching Scientifically book again, and I specifically re-read the pages again on the reasons for the doing exercises through a full ROM. I can't exactly remember word for word what one of his statements says, and I don't have the book with me right now since last week my book has been misplaced somewhere in my home, but he says something like "If baseballs players were to do standard push-ups with a shortened ROM, then there would be no way that anyone of them would be able to pitch a good throw." So what exactly does Mr. Kurz mean by "shortened ROM?" I am still very confused by all this.
You know, I just realized something, Mr. Kurz might of actually said 'shortened position' and not 'shortened ROM.' Additionally, I have thought about this and there probably is a technical yet considerable difference between 'shortened ROM' and 'shortened position' of a given joint. If a joint moves in a 'shortened position' then the joint is moving through the flexed range of motion, which means that the muscles that move that specific joint move only through its
contracted angles or through its
flexed range of motion. The term 'shortened ROM' is more
general and the movement in this case could take place either through its
extended range of motion (through extended angles of muscles) or through its flexed range of motion (through contracted angles of muscles) or a range of motion in between those two ranges, etc.. So in the case of the hip flexors and the muscles (hams and quads) that extend and flex the knee, those muscles would be reduced in flexibility if one were to do bicycling, as bicycling does not allow a full range of extension in the hip and knee joints, which means that those muscles would move within a contracted position throughout the entire duration of such an exercise. With running, your hips and knees are able to move through a full range of extension in the hip and knee joints, which would mean that in this exercise the hip flexors, hams, and quads would move within an
extended position or stretched position throughout the entire duration. I am not absolutely sure on this, but I think this is what you and Mr. Kurz mean or have been trying to tell me as to the reason why running is recommended over cycling. So, is this all correct?
