NSCA CSCS EXAM QUESTIONS WITH
ALL CORRECT ANSWERS
selective recruitment - Answer-fast twitch motor units may occur under certain
circumstances that allow an athlete to inhibit lower-threshold motor units and in their
place activate higher level threshold motor units critical to optimal speed and power
performance
cross education - Answer-training in only one limb can result in an increase in strength
in the untrained limb ~8%
bilateral deficit - Answer-when force produced when both limbs are contracting together
is less than the sum of the forces they produce contracting unilaterally
hyperplasia - Answer-increased number of muscle fibers via longitudinal fiber splitting
as a response to high intensity resistance training
minimal essential strain - Answer-the threshold stimulus that initiates new bone
formation
specificity of loading - Answer-using exercises that directly load a particular region of
the skeleton
osteogenic stimuli - Answer-factors that stimulate new bone formation
structural exercises - Answer-exercises that involve multiple joints, directing force
vectors through the spine and hip and should apply loads heavier than single joint
assistance exercises
progressive overload - Answer-progressively placing greater than normal demands on
the exercising musculature
overtraining - Answer-excessive frequency, volume or intensity of training that results in
extreme fatigue, illness or injury
overreaching - Answer-excessive training on a short term basis
overtraining syndrome - Answer-condition resulting from overtraining, staleness, plateau
or decrease in performance
sympathetic overtraining syndrome - Answer-increased sympathetic activity at rest
parasympathetic overtraining syndrome - Answer-increased parasympathetic activity at
rest and with exercise
,detraining - Answer-cessation of anaerobic training or substantial reduction in
frequency, volume, intensity or any combination that results in decrements in
performance and loss of some physiological adaptations associated with resistance
training
Frank Starling mechanism - Answer-with increased volume the myocardial fibers
become more stretched than at rest, resulting in a more forceful contraction and an
increase in force of systolic ejection and greater cardiac emptying
oxygen uptake - Answer-the amount of oxygen consumed by the body's tissues
maximal oxygen uptake - Answer-the greatest amount of oxygen that can be used at
the cellular level for the entire body
metabolic equivalent of tasks MET - Answer-resting= 3.5 ml of O2/kg/min=1 MET
Fick equation - Answer-VO2=Cardiac output*aVO2difference
arteriovenous oxygen difference - Answer-difference in the oxygen content between
arterial and venous blood
mean arterial pressure - Answer-the average blood pressure throughout the cardiac
cycle
minute ventilation - Answer-the volume of air breathed per minute
anatomical dead space - Answer-alveoli in which poor blood flow, poor ventilation, or
other problems with the alveolar surface impairs gas exchange
myoglobin - Answer-protein that transports oxygen within the muscle cell
hyperoxic breathing - Answer-breathing oxygen enriched gas mixtures
blood doping - Answer-the practice of artificially increasing red blood cell mass as a
means to improve athletic performance
resistance exercise - Answer-a specialized method of conditioning that involves the
progressive use of resistance to increase one's ability to exert or resist a force
preadolescence - Answer-refers to a period of life before the development of secondary
sex characteristics
, epimysium - Answer-continuous tissue encompassing the muscle, consistent with
tendons
tendon - Answer-links muscle to bone
bone periostium - Answer-specialized connective tissue covering all bones
proximal - Answer-closer to the trunk
distal - Answer-farther from the trunk
superior - Answer-closer to the head
inferior - Answer-closer to the feet
origin - Answer-proximal attachment
insertion - Answer-distal attachment
muscle fibers - Answer-long cylindrical cells with many nuclei located on the periphery
of the cell, appear striated
fasciculi - Answer-bundles of muscle fibers
perimysium - Answer-covers bundles of muscle fibers (fascicli)
endomysium - Answer-surrounds each individual muscle fiber
sarcolemma - Answer-continuous with the muscle fibers membrane and endomysium
motor neuron - Answer-nerve cell
neuromuscular junction - Answer-where a nerve cell innervates muscle fibers, each
muscle cell has only one, a motor neuron innervates many muscle fibers
motor unit - Answer-motor neuron and the muscle fibers it innervates
sarcoplasm - Answer-cytoplasm of a muscle fiber, contains contractile components
which consist of protein filaments, other proteins, stored glycogen and fat particles,
enzymes, and specialized organelles such as mitochondria and the sarcoplasmic
reticulum
myofibrils - Answer-contained in the sarcoplasm, contains myofilaments responsible for
contracting the muscle
