Cybex VR2 Owner's Manual
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.
Anatomy - geography, naming by orientation and/or apparent capability (non-functional).
Anchor Points - the points at which a load enters and exits the body and/or limb.
Anterior - anatomical term meaning towards the front. Same as ventral.
Assistant Mover - a muscle that is less effective at performing a specified motion, but does
have a small degree of mechanical ability to help the prime mover. There are many borderline
cases.
Atrophy - reduction in size of cells and tissues.
Axis of Rotation - imaginary line or point which an object rotates.
Bilateral - refers to both sides.
Biolocomotion - a perspective/description of the human body and its mechanics based upon
locomotion. All animals with legs (regardless of numbers) move with the same mechanics.
Gravity is the common denominator.
Biomechanics - the study of motion and the effect of forces on biological systems. In
resistance training it is the analysis of the load placed on a joint by both the muscle and
resistance. Anatomy, Kinesiology, and Physics = Engineering.
Body Composition - the component parts of the body - mainly fat and fat-free weight (lean
body mass).
Calorie - a unit of work or energy equal to the amount of heat required to raise the tempera-
ture of 1 g of water to 1 degree C.
Cam - a mechanical device used to vary leverage. Based on the fact that a muscles
mechanical advantage changes as it moves through a range of motion.
