Which subject would have the HIGHEST basal metabolic rate?
25 year old male
Why do men have a higher basal metabolic rate than women?
Men tend to have more muscle mass than women
In which fitness level would you find a recreationally active 25-year old woman who performs moderate exercise for up to an hour 4-5 days per week and maintains a healthy diet?
Good
Calorimetry is a measure of
heat loss
What is defined as the rate of energy expenditure lying supine immediately after rising and following a 12-18hr fast?
Basal Metabolic Rate
What percentage of your total daily energy expenditure (TDEE) is attributable to exercise?
15-30%
An example of a measure of indirect calorimetry is
blood lactate concentration
Accelerometers are an example of indirect calorimetry.
False;Calculated calorimetry
A VO2 peak test is a type of indirect calorimetry that measures anaerobic fitness level.
False
Heat loss can be used to assess energy expenditure because:
the rate of heat loss and ATP production are proportional
This value accounts for the majority of one's daily energy expenditure:
basal metabolic rate
This lifestyle choice influences basal metabolic rate:
physical inactivity
What anatomical structure explains gender differences in BMR?
skeletal muscle mass
This method of measuring energy expenditure requires place the subjects in a sealed room.
direct calorimetry
Oxygen consumption is correlated to
energy expenditure
A method of determining energy expenditure without actually measuring anything is called
calculated calorimetry
Total daily energy expenditure is composed of what?
basal metabolic rate, thermic effect of feeding, daily physical activity
Direct calorimetry relies on
measurement of body heat production
Indirect calorimetry relies on
measurement of oxygen consumption using a metabolic cart
What percent of your daily EE is accounted for by BMR?
60-75%
What percent of your daily EE is accounted for by exercise?
15-30%
What percent of your daily EE is accounted for by thermic effect of feeding?
10%
