Center of Gravity - the center of a body’s mass. In the human body, it is the point which all parts are
in balance with one another. The COG may be within the body, altered by the position of the body even
to the point of being outside the body (pike position), or altered by the addiction of load to specifi c body
areas.
Circumduction - a circular movement permitted at ball and socket, condylar and saddle joints.Consists
of fl exion, abduction, extension and adduction in sequence.
Circuit Training - a conditioning program consisting of a number of exercises performed at “stations”.
Usually, a given exercise is performed at a station within a specifi ed time; then the athlete moves to the
next station, with its own particular exercise and specifi ed time, then to the next station, and so on.
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 sagittal plane; movement toward the leg.
Eccentric - muscle action in which tension is developed in the muscle while it is lengthening.
Negative work is performed.
