Knowing The Basics of Fitness

Physical fitness is most easily understood by examining its components, or “parts.” There is
widespread agreement that these components are basic: 

1.    Cardiorespiratory Endurance - the ability to deliver oxygen and nutrients to tissues,
       and to remove wastes, over sustained periods of time. Long runs and swims are among
       the methods employed in measuring this component. 

2.    Muscular Strength - the ability of a muscle to exert force for a brief period of time.
       Upper-body strength, for example, can be measured by various weight-lifting exercises. 

3.    Muscular Endurance - the ability of a muscle, or a group of muscles, to sustain repeated
       contractions or to continue applying force against a fixed object. Pushups are often used
       to test endurance of arm and shoulder muscles. 

4.    Flexibility - the ability to move joints and use muscles through their full range of motion.
       The sit-and- reach test is a good measure of flexibility of the lower back and backs of the
       upper legs.

5.    Body Composition is often considered a component of fitness. It refers to the makeup of
       the body in terms of lean mass (muscle, bone, vital tissue and organs) and fat mass. An
       optimal ratio of fat to lean mass is an indication of fitness, and the right types of exercises
       will help you decrease body fat and increase or maintain muscle mass.
