2. Stamina – The ability of body systems to process, deliver, store, and utilize energy.

3. Strength – The ability of a muscular unit, or combination of muscular units, to apply force.

4. Flexibility – the ability to maximize the range of motion at a given joint.

5. Power – The ability of a muscular unit, or combination of muscular units, to apply maximum force in minimum time.

6. Speed – The ability to minimize the time cycle of a repeated movement.

7. Coordination – The ability to combine several distinct movement patterns into a singular distinct movement.

8. Agility – The ability to minimize transition time from one movement pattern to another.

9. Balance – The ability to control the placement of the bodies center of gravity in relation to its support base.
