Moment Arm - (MA) the shortest distance between the action line and the joint axis.

Momentum - determined by mass x velocity. Will remain constant unless the object is acted

upon by another force.

Muscle Contraction - shortening of a muscle and/or development of tension in a muscle.

Muscular Endurance - the ability of a muscle or muscle group to perform repeated

contractions against a light load for an extended period of time.

Neutral - a point between the two extremes of a joint’s range of motion.

Obesity - excess body fat.

Open Kinematic Chain - the ends of the limbs are free to move without causing motion at

another joint. Open chain motions are not predictable because the joints amy function either

independently or in unison. Less mechanically efficient, therefore more stress is placed upon

muscular tissue.

Origin - attachment of a muscle that remains relatively fixed during muscular contraction.

Overload - to exercise a muscle or muscle group against resistance greater than that which is

normally encountered. The resistance (load) can be maximal or near-maximal.

Passive Insufficiency - a two-joint muscle loses the ability to cross-bridge (generate force)

due to full lengthening over its greatest anatomical length due to force created in an opposing

muscle.

Passive Stabilization - due to noncontractile components. Internal stabilization is created by

connective tissue (muscular support is not provided anatomically or physiologically) and external

stabilization is provided by a bench or brace.

Plane of Motion - a two-dimensional flat surface running through an object. Motion occurs in

the plane or parallel to the plane.

Plantar - anatomical term referring to the sole or bottom.

Plantarflexion - movement of the foot down in the sagittal plane; movement away from the

leg.

Posterior - anatomical term meaning toward the back. Opposite of anterior.

Potential Energy - energy by virtue of position.

Power - the product of force and velocity. Work divided by time.
