Running

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:

    These six things doth the Lord hate: yea, seven are an abomination unto him: A proud look, a lying tongue, and hands that shed innocent blood, an heart that deviseth wicked imaginations, feet that be swift in running to mischief, a false witness that speaketh lies, and he that soweth discord among brethren.
    Bible: Hebrew Proverbs 6:16-19.

    “Would you—be good enough—” Alice panted out, after running a little further, “to stop a minute—just to get—one’s breath again?”
    “I’m good enough,” the King said, “only I’m not strong enough. You see, a minute goes by so fearfully quick. You might as well try to stop a Bandersnatch!”
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

    ‘Tis with my mind
    As with the tide swelled up unto his height,
    That makes a still-stand, running neither way.
    William Shakespeare (1564–1616)
