What is the only fuel source that can be used during anaerobic metabolism? - CORRECT
ANSWER✔✔Sugar
__________ serve as the primary fuel for exercise, while ________ are primarily used during
rest and low-intensity physical activity. - CORRECT ANSWER✔✔Carbohydrates, lipids (fats)
Carbohydrates, fats, protein and various associated substrates - CORRECT ANSWER✔✔Aerobic
metabolism can occur using what fuel sources?
1) stored ATP, 2-3) stored creatine phosphate - CORRECT ANSWER✔✔What is the primary fuel
source during 1) a vertical jump, 2) a 3RM deadlift, and 3) a 10-second sprint?
Skeletal muscle (~400g) and the liver (~95g) - CORRECT ANSWER✔✔What are the primary
storage sites for glycogen within the body?
2-5 minutes - CORRECT ANSWER✔✔How much rest is needed to fully recover from an exercise
that significantly drains creatine phosphate stores within a muscle?
Heart rate, stroke volume - CORRECT ANSWER✔✔As a client increases their VO2max, he or she
will have a lower _________ during any sub-maximal exercise intensity; this is mainly attributed
to an increase in __________.
Stroke volume x heart rate - CORRECT ANSWER✔✔Cardiac output is a product of:
,Mitochondria - CORRECT ANSWER✔✔Cellular metabolism using oxygen and various substrates
for fuel occurs in the:
Type I (slow-twitch oxidative) - CORRECT ANSWER✔✔What muscle fiber type has the lowest
capacity to produce force?
Diameter; aerobic - CORRECT ANSWER✔✔Slow oxidative muscle fibers have the smallest
relative _____________ and are primarily fueled via __________ metabolism.
Excess post-exercise oxygen consumption (EPOC) - CORRECT ANSWER✔✔Following high-
intensity exercise, a client may continue to burn additional calories for a number of hours due to
a phenomenon known as:
Calcium - CORRECT ANSWER✔✔What mineral is released from the sarcoplasmic reticulum to
initiate the cascade of events leading to a muscular contraction?
Peripheral fatigue - CORRECT ANSWER✔✔What type of fatigue is associated with reduced
muscle glycogen storage following localized muscular work?
Via increased motor unit recruitment, faster firing rates, and improved firing synchronicity -
CORRECT ANSWER✔✔How is force production improved through neural adaptations?
Exhaustion of ATP/creatine phosphate reserves, tissue acidity, insufficient oxygen, reduced
enzyme activity, tubular system disturbances - CORRECT ANSWER✔✔Identify at least three
primary causes for short-term (acute) muscular fatigue between sets.
Golgi tendon organs - CORRECT ANSWER✔✔If excessive tension is placed upon a given muscle,
________________ send inhibitory signals to reduce motor unit activity and protect the tissue
from potential damage.
, Insulin - CORRECT ANSWER✔✔_________ is the hormone released from the pancreas to help
control blood glucose levels; it also inhibits fat use when in circulation.
Cortisol - CORRECT ANSWER✔✔_______ is an adrenal hormone released in response to high
physiological or psychological stress. It limits carbohydrate uptake, disrupts the protein-sparing
mechanism and can suppress immune system function when chronically released at elevated
levels.
Insulin-like growth factor-1 (IGF-1) - CORRECT ANSWER✔✔What hormone released from the
liver in response to appropriately-devised hypertrophy training signals the body to increase
protein synthesis?
Testosterone, growth hormone, IGF-1 - CORRECT ANSWER✔✔Identify three anabolic hormones
that are released in response to heavy, strenuous resistance training.
Ballistic - CORRECT ANSWER✔✔Throwing a medicine ball for distance requires what type of
muscular contraction?
Carotid - CORRECT ANSWER✔✔What artery is being assessed in under the chin on the neck?
Valsalva maneuver - CORRECT ANSWER✔✔Holding one's breath to increase stability while
lifting a heavy load is referred to as the _______________.
Rate pressure product (RPP); it is calculated using the formula = systolic blood pressure x heart
rate - CORRECT ANSWER✔✔The ____________________ is an estimate of myocardial oxygen
demand and relative stress placed upon the heart.
Shoulder flexion - CORRECT ANSWER✔✔What is the biomechanical term for movement at the
shoulder during a frontal raise?
What is the only fuel source that can be used during anaerobic metabolism? - CORRECT
