What is the only fuel source that can be used during anaerobic metabolism? -
ANSWER Sugar
__________ serve as the primary fuel for exercise, while ________ are primarily
used during rest and low-intensity physical activity. - ANSWER Carbohydrates,
lipids (fats)
Carbohydrates, fats, protein and various associated substrates - ANSWER Aerobic
metabolism can occur using what fuel sources?
1) stored ATP, 2-3) stored creatine phosphate - 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) - ANSWER What are the primary
storage sites for glycogen within the body?
2-5 minutes - 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 - 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 - ANSWER Cardiac output is a product of:
Mitochondria - ANSWER Cellular metabolism using oxygen and various substrates
for fuel occurs in the:
Type I (slow-twitch oxidative) - ANSWER What muscle fiber type has the lowest
capacity to produce force?
Diameter; aerobic - ANSWER Slow oxidative muscle fibers have the smallest
relative _____________ and are primarily fueled via __________ metabolism.
Excess post-exercise oxygen consumption (EPOC) - 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 - ANSWER What mineral is released from the sarcoplasmic reticulum to
initiate the cascade of events leading to a muscular contraction?
Peripheral fatigue - 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 - 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 - ANSWER Identify at least
three primary causes for short-term (acute) muscular fatigue between sets.
Golgi tendon organs - 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 - ANSWER _________ is the hormone released from the pancreas to help
control blood glucose levels; it also inhibits fat use when in circulation.
Cortisol - 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) - 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 - ANSWER Identify three anabolic hormones
that are released in response to heavy, strenuous resistance training.
Ballistic - ANSWER Throwing a medicine ball for distance requires what type of
muscular contraction?
Carotid - ANSWER What artery is being assessed in under the chin on the neck?
Valsalva maneuver - 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 - ANSWER The ____________________ is an estimate of
myocardial oxygen demand and relative stress placed upon the heart.
Shoulder flexion - ANSWER What is the biomechanical term for movement at the
shoulder during a frontal raise?
Shoulder adduction - ANSWER What action is performed at the glenohumeral joint
during the concentric phase of the pull-up exercise?
Hip extension - ANSWER What is the primary movement performed during the
concentric phase of the dumbbell Romanian deadlift?
Quadriceps - ANSWER What is the prime mover during the front squat exercise?
