Closed Chain Kinetic Exercise - a series of rigid links interconnected by a series of pincentered joints.
These are constructed so that motion at one joint will produce motion at all the joints in the system.
Produces greater mechanical effi ciency at the risk of increased joint loading. Leg press, bench press.
Close-Packed Position - all synovial joints have a position where joint surfaces are maximally congruent
and the ligaments and capsule are maximally taut.
Collagen - a fi brous protein that serves as the major component of ligaments and tendons.
Compression - two forces acting along the same line towards each other that constitute a compressive
load or compressive stress.
Concentric action - contraction of a muscle resulting in shortening of the muscle.
Connective Tissue - comprised of mostly the proteins collagen and elastin with water; includes tendons,
ligaments, bursae, cartilage, disks, menisci, fascia and bone.
Cross-bridge - the connection and intertwining of the actin and myosin fi laments in a myofi bril relative to
a muscular contraction.
Curvilinear Motion - the frequently occurring combination of rotatory and translatory motions.
Distraction - two forces acting along the same line and in opposite directions, they constitute a
distractive, tensile load or tensile stress.
Diathrodial Joint - ball and socket joint.
Distal - furthest from the attached end of the limb; away from the body.
Dorsal - pertaining to the back; opposite of ventral, palmar or plantar.
Dorsifl exioni - movement of the foot up in the sagitial plane; movement toward the leg.
Eccentric - muscle action in which tension is developed in the muscle while it is lengthening.
Negative work is performed.
Eccentric Action - a muscle contraction incapable of overcoming the resistance imposed;
the overall muscle length increases.
Endurance - the ability to persist in performing some physical activity.
Energy - the capacity to perform work.
Energy (kinetic) - energy associated with motion.
Energy (potential) - energy by virtue of position.
Energy System - one of three metabolic systems involving a series of chemical reactions resulting
in the formation of waste products and the manufacture of ATP.
Eversion - movement of the sole of the foot outward; opposite of inversion.
Extension - movement at a joint, bringing two parts into or towards a straight line, increasing the angle
of the joint. Returning to anatomical position from a position of fl exion in the sagitial plane.
