Agility -- The inherent ability to change direction quickly and efficiently\ Anaerobic exercise -- Activity done at such a fast pace the heart cannot supply oxygen as fast as the body uses it\ Balance - Ability to maintain the equilibrium of the body in a fixed position or while moving\ Flexibility -- Range of motion at a joint\ Muscular endurance -- Ability to use skeletal muscles for long periods of time\ Dynamic stretch -- method of increasing joint range (flexibility) involving slow movements\ Muscular strength -- the ability of muscles to exert force one time\ Overload principle -- exposing the muscles, joints, and cardiovascular system to more work and stress than is normally\ experienced\ Reaction time -- the amount of time necessary to initiate a response to a stimulus\ Recovery time -- amount of time necessary for the body to regain normal conditions after exercise\ Repetition -- the number of times a motion is repeated during specific exercise\ Set -- group of repetitions\ Speed -- the amount of time it takes the body to move from one point to another\ Warm up -- mild exercise done to get ready for more vigorous exercise\ Atrophy -- decrease in muscle size\ Hypertrophy -- increase in muscle size\ Barbell -- bar used with free weights\ Dumbbell -- hand held with a fixed weight\ Muscular power -- combination of strength and speed\ Specificity -- exercise for a specific muscle group\ Lactic acid -- a waste product built up in the body as a result of exercise\ Aerobic exercise -- activity done at a pace where the heart can supply as much oxygen as the body needs\ Anterior -- front of the body\ Posterior -- back of the body\ Medial - middle
