NSCA - CSCS - CHAPTER 2 QUESTIONSAND ANSWERS WITH SOLUTIONS 2024
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 - ANSWER the object's rotational speed, measured in radians per second
antagonist - ANSWER a muscle that can slow down or stop the movement
biomechanics - ANSWER the mechanisms through which the musculoskeletal components interact to
create movement
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
first-class lever - ANSWER a lever for which the muscle force ad resistive force act on opposite sides of
the fulcrum
fleshy attachment - ANSWER a form of muscle attachment in which the epimysium is continuous with
the perimysium of the muscle
fluid resistance - ANSWER the resistive force encountered by an object moving through a fluid (liquid or
gas), or by a fluid moving past or around an object or through an opening
form drag - ANSWER a form of fluid resistance that results from the way in which a fluid presses against
the front or rear of an object passing through it
friction - ANSWER the resistive force encountered when one attempts to move an object while it is
pressed against another
frontal plane - ANSWER the plane running parallel to the long axis of the body
