agonist Answer-also called the prime mover. The muscle most directly involved in
bringing about a movement
anatomical position Answer-the body is erect, the arms are down at the sides, and the
palms face forward
angle of pennation Answer-angle between the muscle fibers and an imaginary line
between the muscle's origin and insertion; 0° corresponds to no pennation
angular displacement Answer-the angle through which an object rotates, for which the SI

bracketing technique Answer-a form of acceleration training in which the athlete
performs the sport movement with less than normal and greater than normal resistance
cartilaginous joint Answer-a slightly movable joint in which cartilage unites bony surfaces
classic formula Answer-the load lifted divided by body weight to the two-thirds power
concentric muscle action Answer-a muscle action in which the muscle shortens because
the contractile force is greater than the resistive force. The forces are generated within the
muscle and acting to shorten it are greater than the external forces acting as its tendons to
stretch it
distal Answer-away from the center of the body
dorsal Answer-toward the posterior of the body
eccentric muscle action Answer-a muscle action in which the muscle lengthens because
the contractile for is less than the resistive force. The forces generated within the muscle and
acting to shorten it are less than the external forces acting as its tendons to stretch it
fibrous attachment Answer-a band of tough, inelastic fibrous tissues that connects a
muscle with its bony attachment
