NSCA-CSCS Chapter 5
Type IIx - answerWhich muscle fiber type has the GREATEST potential to, when trained
in a specific way, CHANGE into a more aerobic or oxidative form?
Anaerobic Training - answerA 17 year old american football player just participated in a
weight training session combined with a plyometric workout. What kind of training is
this?
Neural Adaptations - answerA 14 year female volleyball athlete has recently started a
resistance training program and has seen significant gains in just three weeks. What is
responsible for these initial gains?
Phosphagen System and Anaerobic glycolysis - answerFor a 100m sprinter to be
successful they must work what work systems?
Power gains will be compromised - answerA weightlifter adds 30 minutes of intense
(>75% VO2 max) stationary bicycle riding every other day to her resistance training
program. What describes the GREATEST effect this addition will have on her
performance?
Front Squat - answerA 50-year old female triathlete is concerned about osteoporosis.
What exercise is MOST beneficial for improving her bone mineral density?
Type I muscle fibers - answerWhat muscle fiber types are "bypassed" as a result of
selective recruitment that allows an Olympic weightlifter to generate maximum power
during a 1RM snatch?
Large muscle mass exercises and High intensity and volume - answerWhat are the
MOST effective stimulants of growth hormone production from a resistance training
workout?
Nervous System - answerThe INITIAL decrease in muscular strength caused by
detraining is due to undesired changes in which system?
Consists of high-intensity, intermittent bouts of exercise such as weight training;
plyometrics drills; and speed, agility, and interval training. - answerAnaerobic Training
Based on the relationship between motor unit twitch force and recruitment threshold. -
answerSize Principle
The Size Principle - answerThe recruitment and decruitment of motor units in an orderly
manner is governed by what?
, Fast twitch muscle fibers may be recruited before slow twitch fibers under certain
circumstances that allow an athlete to inhibit lower-threshold motor units and in their
place activate the higher-threshold motor units critical to optimal speed and power
performance. - answerSelective Recruitment
The interface between the nerve and skeletal muscle and is another potential site for
the occurrence of neural adaptations from anaerobic training. - answerNeuromuscular
Junction (NMJ)
This is a common research tool used to examine the magnitude of neural activation
following training. - answerElectromyography (EMG)
Greater Neural Activation - answerAn increase in EMG indicates what?
Training only one limb can result in an increase in strength in the untrained limb. -
answerCross-education
This means that the force produced when both limbs are contracting together is less
than the sum of the forces they produce when contracting unilaterally. - answerBilateral
Deficit
Refers to the muscular enlargement resulting from training, primarily owing to an
increase in the cross-sectional area (CSA) of the existing fibers. - answerHypertrophy
Structural Proteins - answerTitin and Nebulin are considered to be what?
This is the formation of muscular tissue, particularly during embryonic development. -
answerMyogenesis
Results in an increase in the number of muscle fibers via longitudinal fiber splitting as a
response to high-intensity resistance training. - answerHyperplasia
Only in animals, but the findings are controversial in humans. - answerHyperplasia has
been observed in whom?
In response to this osteoblasts migrate to the bone surface and begin bone modeling.
Increasing the strength of the bone. - answerMechanical Loading
These manufacture and secrete proteins - primarily collagen molecules- that are
deposited in the spaces between bone cells to increase strength. - answerOsteoblasts
The intercellular substance of bone tissue consisting of collagen fibers, ground
substance, and inorganic bone salts. - answerBone Matrix
