what information would NOT be used to determine above and below lactate threshold running paces
which of the following measurements would indicate attainment of VO2 ma during a GXT?
Platueaing or decreasing in V02 with increasing workload
In theory, EPOC period can NOT :
is characterized by excess oxygen consumption over that seen during activity.
a RER value of ______ would indicate that fats are the primary fuel source, whereas a value of ______ would indicate that carbs are the primary fuel source.
.7 , 1
List three field tests to estimate aerobic power (VO2 max)
Mile Run, 12 minute run/walk test, step test
as exercise increases= stop using fat but shift to carbs; better trained= shifts to right
as heart rate increases ______ blood pressure increases, as _______ blood pressure stays the same.
Nodes of Ranvier
small gaps of exposed axon, between the segments of myelin sheath, where action potentials are transmitted
After an electrical impulse crosses the neuromuscular junction is travels down the ________
Muscle growth from long-term resistance training is primarily due to the increase in the:
The size of the muscle fibers
The preferred term for an exercise movement that involves the same resistance throughout the range of motion is:
Dynamic constant external resistance
The velocity of a nerve impulse transmission is primarily determined by:
myelination and diameter of the neurons
The spread of electrical impulse among the muscle fibers of the heart:
is achieved through intercalated discs
What technique does the body NOT use to control blood flow during activity?
altering the hemoglobin content of the blood
the fact that an increase in end-diastoltic ventricular volume increases the stoke volume of the heart is an illustration of:
Frank-Starling law of the Heart
during exercise, the time spent in diastole and systole
is decreased with the greatest decrease occurring in diastole
a form of exercise that utilizes the stretch-shortening cycle, termed ________, helps in the development of muscular power.
________ nervous system controls the physiological functions that are unconscious in nature.
Specialized nuerons that are found only in the CNS and connect one neuron to another neuron are called _______
If the end-diastolic volume increases and end-systolic volume remains constant, stroke volume will ________.
with moderate to heavy exercise, changes in sodium excretion and urine output occur. What is the purpose?
to conserve electrolytes
The use of oxygen in aerobic metabolism and production of carbon dioxide is referred to as:
The nasal passages and structures prior to respiratory bronchioles do all of the following except:
Cools the air
The blood pressure of the pulmonary system:
is lower than systemic circulation. which protects the respiratory membrane.
The window of opportunity in which protein should be consumed to improve protein synthesis:
ends several hours after resistance exercise.
The _______ __________ is the calculation of breathing frequency, per minute by the amount of air moved per breath.
Compared to the value measured at sea level, when a subject works at the same work rate at 3,000 meters altitude, the heart rate is:
Pulmonary ventilation is higher at altitude than at sea level for any work rate, this is necessary due to the:
lower air density
Distance-running performances are generally not as good when conducted at a high altitude because, This is due to:
which of the following is an adaptation that the body makes to chronic heat stress:
early onset of sweating
The primary concern with exercise at altitude is:
lower barometric pressure limiting oxygen transfer in the blood
_________ refers to training that utilizes various modes of exercise to improve cardio fitness.
_______ refers to planned variation in training, with the goal of optimizing physical performance
Minimum recommendation to promote and maintain health:
30 minutes of moderate exercise (moderate), 20 mins of vigorous exercise 3 days a week, Combination of the two (2 mod, 2 vig) Resistance training with main muscle groups!
