An adult weighing 125 to 195 pounds will burn 29 to 44 calories per hour while sitting. While walking, the number of calories expended will increase by approximately what rate?

A. It will double.
B. It will be four times greater.
C. It will triple.
D. It will be five times greater.

Answer :

Final answer:

The caloric expenditure for an individual who transitions from sitting to walking will usually double, or even triple, depending on the person's physical characteristics and the intensity of the walking movement.

Explanation:

To determine how much the caloric expenditure increases when an individual transitions from sitting to walking, we need more specific numbers. However, as the question suggests, the act of standing and walking significantly increases the body's caloric expenditure compared to sitting. This increase depends on several factors, including body mass, activity level, and the intensity of the walk.

The equation for this can be represented as: Number of calories burnt per hour = BMR/24 * MET value of the activity, where MET (Metabolic Equivalent of Task) is a measure of energy expenditure for activities.

For example, the MET for sitting quietly is considered 1, while for walking it's approximately 2.5 - 3.5, depending on the speed. Therefore, we can say the caloric expenditure for the same individual will be at least double to triple when transitioning from sitting to walking.
