Total energy expenditure is broken down into two components-resting metabolism and physical activity.
Indicate whether the statement is true or false
Q. 2Which of the following does NOT occur as a result of low-intensity, steady state exercise lasting more than 20 minutes?
a. The energy system that predominates is oxidative phosphorylation
b. The percentage of energy from fat decreases
c. The percentage of energy from fat increases
d. There is an increase in fatty acid release from adipocytes and uptake by muscle
Q. 3A simple and commonly used estimate of resting energy expenditure is 1 kcal per kilogram body weight per hour for both men and women.
Indicate whether the statement is true or false
Q. 4The elevated oxygen consumption during recovery from an exercise bout is called EPOC or:
a. oxygen debt.
b. oxygen deficit.
c. anaerobic threshold.
d. fat burning zone.
Q. 5Those who work with athletes, particularly endurance athletes, should use the Cunningham equation to predict RMR because it may better account for the higher amount of lean body mass in trained athletes.
Indicate whether the statement is true or false
Q. 6Which of the following is true as exercise intensity increases?
a. At a certain point aerobic metabolism is shut off and anaerobic metabolism is turned on.
b. When the anaerobic threshold is reached muscles stop getting oxygen and suddenly begin producing lactate, which can be measured in the blood.
c. There is a point in ultraendurance activities where fat metabolism stops completely and protein metabolism supplies nearly all of the energy.
d. Energy is supplied in a smooth continuum where one system may predominate depending upon the intensity.
