Synergist - occurs during the action of two muscles, both of which have a common joint action and each
of which has a second action that is antagonistic or opposing to the other. True synergy is simply the
stabilization of one muscle to prevent any action in one of the joints traversed by a multi-joint muscle.
Synovial Fluid - transparent, viscous lubricating fl uid found in joint cavities, bursae and tendon sheaths.
Tendons - cords of dense fi brous tissue that connect muscle to bone.
Tertiary Joint - a complex joint structure (wrist/ankle-subtalor), designed for fi nely controlled movements.
Torque - the ability of a force to produce movement around an axis.
Training - a program of exercise designed to improve the skills and increase the energy capacities of an
athlete for a particular event.
Translatory Motion - (linear) the movement of an object in a straight line.
Unilateral - refers to only one side.
Validity - the extent to which a measurement or information is relevant or meaningful; appropriate to
the end in view and supported by objective truth.
Vector - an arrow which represents a force’s point of application, action line or direction indicating pull
or magnitude of force being exerted.
Vector Shift - the alteration of a load as it is transferred between the anchor points through a segment’s
kinematic chain.
Velocity - the rate at which an objects position changes with time; that is the total change in position
divided by the total change in time: V-d/t.
Weight - the weight of an object is the gravitational force exerted on it by the earth. W=mg, where
g = gravitational acceleration.
Work - W = Fd. The amount of work performed is equivalent to the force applied to an object times the
distance the object is moved.
