NSCA CSCS EXAM CHAPTERS 1 & 2
WITH COMPLETE SOLUTIONS
-The arrangement of myosin (thick) and actin (thin) filaments gives skeletal muscle its
striated appearance. - ANS-
•Motor units are composed of muscle fibers with specific morphological and
physiological characteristics that determine their functional capacity. - ANS-
•Proprioceptors are specialized sensory receptors that provide the central nervous
system with information needed to maintain muscle tone and perform complex
coordinated movements. - ANS-
•The cardiovascular system transports nutrients and removes waste products while
helping to maintain the environment for all the body's functions. The blood transports
oxygen from the lungs to the tissues for use in cellular metabolism; and it transports
carbon dioxide from the tissues to the lungs, where it is removed from the body. - ANS-
Acceleration definition - ANS-The change in velocity per unit of time
Actin - ANS-thin filaments
Activation of muscles - ANS-Arrival of the action potential at the nerve terminal causes
the release of acetylcholine, once a sufficient amount of acetylcholine is released an
action potential is generated across the sarcolemma and the fiber contracts
Advantages of free weights - ANS-whole-body training, simulation of real-life activities
Agonist muscle - ANS-The muscle primarily responsible for movement of a bone. (prime
mover)
all-or-none principle - ANS-The principle that all of the muscle fibers in the motor unit
contract and develop force at the same time; a stronger action potential cannot produce
a stronger contraction
anatomical position - ANS-To stand erect with arms at the sides and palms of the hands
turned forward
anatomy of synovial joint - ANS-Bone ends covered with smooth hyaline cartilage; joint
is enclosed in a capsule filled with synovial fluid; usually with additional ligament and
cartilage
, Angular work and power - ANS-Angular displacement (angle through which an object
rotates)
antagonist muscle - ANS-The muscle opposite the agonist, can slow or stop the
movement
axial vs appendicular skeleton - ANS-skull, vertebral column (c1- coccyx), ribcage,
sternum
vs.
shoulder girdle, pelvic girdle, bones of the arms, wrists, hands, bones of ankles, legs,
and feet
Back injury in resistance training - ANS-- Lower back is vulnerable
- Resistance training should be generally performed with lower back in moderately
arched position
biaxial joint - ANS-operate in two perpendicular axes (ankle and wrist)
Biomechanical factors in human strength - ANS-Neural Control
Muscle Cross-Sectional Area
Arrangement of Muscle Fibers
Muscle Length
Joint Angle
Muscle Contraction Velocity
Joint Angular Velocity
Strength-to-Mass Ration
Body Size
Biomechanics definition - ANS-The mechanisms through which components interact to
create movement
bipennate muscle - ANS-forms an angle with a tendon; fibers on both sides of tendon;
ex: rectus femoris
Bone periosteum - ANS-a specialized connective tissue covering all bones
bracketing technique - ANS-athlete performs the sport movement with less than normal
and greater than normal resistance; a form of acceleration training
Calcium and ATP are necessary for crossbridge cycling with actin and myosin filaments
- ANS-
Cardiovascular system notes - ANS-- Blood flow
- Conduction System
-EKG
