Exam 6: Measurement of Energy in Food

Not an approach to accurately quantifying the energy generated during rest and physical activity?

Physical activity increases with age, and sufficient activity becomes more common among women than men.

An airtight chamber with an oxygen supply where a person lives and works for an extended time period.

Coefficients of digestibility average 97% for carbohydrates, 95% for lipids, and 92% for proteins.

Measuring oxygen uptake to estimate energy expenditure.

One MET represents an adult's average seated resting oxygen uptake or energy expenditure-about 250 mL O₂·min^-1, 3.5 mL O₂·kg^-1·min^-1, or 1 kcal·kg^-1·h^-1.

For each RQ value, a corresponding caloric value exists for each liter of oxygen consumed.

One metabolic equivalent (MET) represents an adult's average seated resting oxygen consumption or energy expenditure.

Thermic effect of feeding is the minimum energy requirement to sustain the body's functions.

Method to calculate the metabolic mixture during physical activity.

A general value for the gross heat of combustion for protein is 5.65 kcal·g^-1.

Indirect calorimetry.

Obese individuals usually exhibit greater digestive efficiency compared with lean counterparts.

A high-fiber meal has __________ total energy absorbed than a fiber-free meal of equivalent caloric content.

The MET provides a convenient way to rate oxygen consumption during exercise compared with a resting baseline.

Excessive fat catabolism produces excessive urea.

Considered a non-weight-bearing activity?

Has the highest resting metabolic rate.

The respiratory quotient is the ratio of CO₂ produced to O₂ consumed during macronutrient combustion.

The net energy expenditure equals gross energy expenditure added to the energy requirement of rest for an equivalent time.
