Running
Outdoor Running🏃♀️
Running is a method of terrestrial locomotion
allowing humans and other animals to move rapidly on foot.
It is a type of gait characterized by an aerial phase in which all feet
are above 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 stance leg or legs in an
inverted pendulum fashion.
A 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.
