Glossary
Abduction - movement away from the mid-line of the body.
Acceleration - the rate at which an object’s velocity changes with time; that is the change of velocity
divided by the time interval.
Accuracy - freedom from error. Degree of conformity of a measure to a standard or a true value.
Action Line - the direction of pull created by the fi bers or tendons of the muscle at the point of
application.
Active Insuffi ciency - a two joint muscle loses the ability to cross-bridge (generate force) due to full
shortening over its greatest anatomical length and tension created in an opposing muscle (antagonist).
Active Range of Motion - the degree of motion that occurs between two adjacent segments through
voluntary contraction of the agonist.
Active Stabilization - provided by an internal force. Static stabilization is provided through an isometric
contraction where dynamic stabilization is a series of motions. Dynamic stabilizers maintain the relative
positions of the segments, preventing undesirable or unnecessary motions due to external forces as well
as artifacts of internal forces. May also refer to the concentric/eccentric contractions of a muscle acting in
a force couple to produce motion while maintaining a relatively fi xed axis of rotation.
Adipose tissue - fat tissue.
Adduction - movement towards the mid-line of the body.
Agonist - (prime mover) the muscle most involved in producing a movement.
Aerobic - utilizing oxygen.
Aerobic endurance - the ability to persist in physical activities that rely heavily upon oxygen for energy
production.
Anabolic - pertaining to the synthesis of complex substances from simpler substances, especially to the
synthesis of body proteins from amino acids.
Anaerobic - without oxygen.
Anaerobic endurance - the ability to persist in physical activities of short duration that require high
rates of energy expenditure. These high rates of energy expenditure cannot be met solely by aerobic
metabolism.
Anthropometrics - measurements and relationships of length and girth of body parts.
Antagonist - the muscle in opposition to the agonist.
Anatomical Position - standing erect, with feet and palms facing forward.
Anatomical Pulley - a bone or skeletal prominence that alters the direction of the pull of a muscle to
increase the muscle’s mechanical advantage.
