Th evolution of athletes and sports always intrigues me, especially the reasoning behind the change. What is the determining factor for a sort evolving? Is it better equipment, better training, better diets, or 100 other variables? Check out the below montage made about the gymnastics uneven bars which shows in a nice montage format the evolution from the 1950s to 2010 of the uneven bars. The evolution is quite amazing and worthy of conversation. The New York Times ran a piece earlier this month which did the same thing , but for the 100M sprint. You can view that HERE.
