Prime Mover - (agonist) a muscle that is mechanically optimal to produce a specific motion
at a joint. There can be more than one prime mover for a particular motion, and a specific
muscle can be a prime mover for more than one motion at a joint.
Progressive Resistance - overloading a muscle or muscle group consistently throughout the
duration of a weight-resistance program.
Pronation - a triplanar motion at the subtalar joint consisting of abduction, depression and
eversion, resulting in lowering of the longitudinal arch of the foot. Position of the forearm with
the palm facing down.
Protein - a basic foodstuff containing amino acids.
Proximal - towards the attached end of the limb or origin.
Range of Motion - the amount of motion available to a joint within the anatomical limits of the
joint structure. Can be classified as Passive (movement produced via a force outside the limb),
Active (movement produced by muscles within the limb) or Resisted (movement challenged
under additional load). The amount of resistance will affect the range of motion with direct
proportion.
Reciprocal Inhibition - contraction of agonist causes relaxation of antagonist.
Reliability - the extent to which an experiment, test or measuring procedure yields the same
results on repeated trials. Also known as reproducibility or repeatability.
Repetition Maximum (RM) - the maximum load that a muscle or muscle group can lift in a
given number of repetitions before fatiguing. For example, an eight-RM load is the maximum
load that can be lifted eight times.
Repositioners - muscles that lift the extremity and move it to a new location allowing the
prime movers to again accept load or propel.
Response - a sudden temporary adjustment in physiological function brought on by a single
exposure to exercise, e.g., the rise in heart rate associated with an exercise bout.
Rotary Motion - (radial or angular) the movement of an object around a fixed axis in a curved
path.
S.A.I.D. Principle - Specific Adaptation to Imposed Demand. A muscle will gain strength in
the specific ranges of motion and speeds in which it is trained.
Sagittal Plane - Imaginary line that divides the body, or any of its parts, into right and left
sections.
Scoliosis - a lateral curvature of the vertebral column, usually in the thoracic area.
Secondary Joint - hinge joints that have a singular function (elbow/knee). Muscles are
situated on either side of these joints in virtual, if not real, pairings.
Set - in an interval training program, a group of work and relief intervals. In weight lifting, the
number of repetitions performed consecutively without resting.
