World's Oldest Sport
Running is a means of terrestrial locomotion allowing a human or an animal to move rapidly on foot. It is simply defined in athletics terms as a gait in which at regular points during the running cycle both feet are off the ground. This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity
vaults over the legs in an inverted pendulum fashion. A characteristic
feature of a running body from the viewpoint of spring-mass mechanics,
is that changes in kinetic and potential energy within a stride occur
simultaneously, with energy storage accomplished by springy tendons and
passive muscle elasticity.The term running can refer to any of a variety
of speeds ranging from jogging to sprinting.The ancestors of mankind developed the ability to run about four and a half million years ago, probably in order to hunt animals. Competitive running grew out of religious festivals in various areas. Records of competitive racing date back to the Tailteann Games in Ireland in 1829 BCE, while the first recorded Olympic Games took place in 776 BCE.
