Was out in Central Park yesterday to watch the USA 8K Championships - most of the male Olympian stars pulled out of the race before the start - but the women were there in full force - runners at this caliber make it look so easy - and when I look at these people running - their bodies in motion - how they flow - I am reminded of the person credited with first examining bodies in motion - running, " Etienne-Jules Marey" - of France. Marey hoped to merge anatomy and physiology in studying human locomotion. That image on the right is an illustration of how he would have a runner wear an elaborate apparatus intended to register his different paces. Keep in mind this was in the late 1800's and the devices (polygraphs, sphygmographs, dromographs and other myographs - stuff that measured physiology, blood pressure for example) were recording instruments that ultimately produced graphs. He succeeded in analyzing man running and demonstrated the walking motion of humans (and horses, the the flight of birds and insects). That above on the left are 2 chronophotographics (Marey's imaging process) of a runner taken from overhead in 1887 . Marey’s chronophotographs were the first images that attempted to explain exactly what happens when the body moves. Now if I can only get my body moving like those Olympians I watched yesterday in Central Park....Have a great day.
