Balance is a skill-related fitness component that
refers to the ability of the body to maintain in its equilibrium while
stationary or moving. A person who has good balance is able to maintain his
body within the line of gravity with minimal postural deviations. Maintaining

hearing. A person who has poor balance are not able to perform certain
activities that require special orientation and awareness.
