NSCA - CSCS - Chapter 2
Acceleration - answer the change in velocity per unit time
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 unit is the radian
angular velocity - answerthe object's rotational speed, measured in radians per second
antagonist - answera muscle that can slow down or stop the movement
biomechanics - answerthe mechanisms through which the musculoskeletal components
interact to create movement
bracketing technique - answera form of acceleration training in which the athlete
performs the sport movement with less than normal and greater than normal resistance
cartilaginous joint - answera slightly movable joint in which cartilage unites bony
surfaces
classic formula - answerthe load lifted divided by body weight to the two-thirds power
concentric muscle action - answera 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 - answeraway from the center of the body
dorsal - answertoward the posterior of the body
eccentric muscle action - answera muscle action in which the muscle lengthens
because the contractile for is less than the resistive force. The forces generated within
