There is a new book out about all of the sports of the world. The cover of the book is made of astroturf, so you can't miss it. In the section on track and field, it said that most world-class long jumpers prefer the hitch style. I wonder why this is?
I thought that hitch and hang were the only two LJ techniques, but there is another one. Glide? I don't recall right now. But it said under this style that it is important to move one's arms a certain way in order to propel the jumper through the air. This contradicts the many posters here who say that once you are in the air, nothing one does affects the distance of the jump. I guess this means you can ball up into a cannon ball, and the results would be the same.
