There are ten recognized general physical skills, and they are all practiced regularly in training. You are as fit as your competency in each of these ten skills.

  1. Endurance (cardio-vascular/respiratory) – The ability of body systems to gather, process, and deliver oxygen.
  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 body’s center of gravity in relation to its support base.
  10. Accuracy – The ability to control movement in a given direction or at a given intensity.

Improvements in endurance, stamina, strength, and flexibility come about through training. Training refers to activity that improves performance through a measurable organic change in the body. (1 – 4)

By contrast improvements in coordination, agility, balance, and accuracy come about through practice. Practice refers to activity that improves performance through changes in the nervous system. (7 – 10)

Power and speed are adaptations of both training AND practice. (5 & 6)
