Energy Requirements Quiz

What is the Respiratory Exchange Ratio (RER)?

• The ratio of CO2 released to oxygen consumed

• The amount of energy used by the body

• The measurement of basal metabolism

• The caloric equivalence of energy expenditure

What factors affect BMR?

• Age, height, growth, body composition

• Diet, exercise, sleep, hydration

• Genetics, environment, stress, hormones

• All of the above

What is the effect of fever on BMR?

• Lowers BMR

• Raises BMR

• No effect

• Depends on the individual

What is the equation to estimate energy burned during an activity?

• activity level (MET) x duration x weight = total kcal burned

• weight x height x age = total kcal burned

• duration x MET = total kcal burned

• activity level x weight = total kcal burned

What is the thermal effect of food (TEF)?

• Energy expended during digestion and absorption

• Energy used during physical activity

• Energy required for basal metabolic functions

• Energy stored as fat

What is the definition of energy balance?

• A state where energy intake equals energy expenditure

• A state where energy intake exceeds energy expenditure

• A state where energy expenditure exceeds energy intake

• A state of weight loss

What is the formula for estimating energy requirement (EER)?

• EER = BMR x Physical Activity Level

• EER = BMR + TEA + TEF + AT

• EER = Total kcal burned / weight

• EER = BMR + weight

How does hydration status influence BMR?

• Only extreme hydration affects BMR

• Hydration raises BMR

• Hydration has no effect on BMR

• Dehydration lowers BMR

What role does muscle mass play in energy expenditure?

• Lower muscle mass increases energy expenditure

• Higher muscle mass increases energy expenditure

• Muscle mass only affects energy during exercise

• Muscle mass has no impact on energy expenditure

What is the significance of the thermic effect of exercise (TEE)?

• Energy used for digestion

• Energy expended during physical activity

• Energy required for basal metabolic functions

• Energy stored in muscles
