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

hyperventilation - Answer-increased pulmonary ventilation

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
