Running
Running is a means of terrestrial locomotion allowing humans and other animals 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.

Famous quotes containing the word running:
“Executives are like joggers. If you stop a jogger, he goes on running on the spot. If you drag an executive away from his business, he goes on running on the spot, pawing the ground, talking business. He never stops hurtling onwards, making decisions and executing them.”
—Jean Baudrillard (b. 1929)
“People run away from the name subsidy. It is a subsidy. I am not afraid to call it so. It is paid for the purpose of giving a merchant marine to the whole country so that the trade of the whole country will be benefitted thereby, and the men running the ships will of course make a reasonable profit.... Unless we have a merchant marine, our navy if called upon for offensive or defensive work is going to be most defective.”
—William Howard Taft (1857–1930)
“I must down to the seas again for the call of the running tide Is a wild call and a clear call that may not be denied.”
—John Masefield (1874–1967)
