Force - an interaction between two objects, in the form of a push or pull, that may or may not
produce motion, Force = mass x acceleration.
Force Angle - (FA) the angle between the action line and the lever, on the side of the joint
axis.
Force Couple - concentric/eccentric contractions of opposing muscles acting to produce
motion while maintaining a relatively fixed axis of rotation.
Frontal Plane - (coronal) imaginary line that divides the body into anterior and posterior
halves; lies at a right angle to the sagittal plane.
Fulcrum - the support on which a lever rotates in moving or lifting.
Hyperextension - continuation of the movement of extension past the neutral position.
Hypertrophy - increased cell size leading to increased tissue size.
Impulse - the change in momentum.
Inertia - the tendency of a body to remain at rest or continue in motion unless disturbed by
an external force.
Inferior - a lower position upon or within the body.
Insertion - the more distal attachment site of a muscle. The movable part or attachment of a
muscle as opposed to origin.
Intermittent Work - work sessions interrupted by rest sessions.
Internal Forces - act on the body and arise from sources within the human body.
Inversion - moving the sole of the foot inward. Opposite of eversion.
Isokinetic - action in which the rate of movement is constantly maintained through a specific
range of motion even though maximal force is exerted.
Isokinetic Contraction - a muscular contraction through a range of motion at a constant
velocity.
Isometric - a contraction in which movement is produced but no movement occurs.
Isometric (static) Contraction - a muscular contraction in which there is no change in the
angle of the involved joint(s) and little or no change in the length of the contracting muscle.
Isotonic - a contraction in which movement is produced.
Medial Rotation - movement around an axis and toward the mid-line of the body. Also
termed internal rotation.
Medial - aspect nearest the mid-line of the body; pertaining to the center. Opposite of lateral.
Metabolism - the sum total of the chemical changes or reactions occurring in the body.
