Final answer:
The emphasis should be placed on the intensity of the aerobic activity, recalculation of energy expenditure with weight loss, and resting energy expenditure of the client. option3
Step-by-step explanation:
The emphasis should be placed on the intensity of the aerobic activity when considering total energy expenditure for weight loss or maintenance. The intensity of the aerobic activity directly affects the number of calories burned during the exercise. Higher intensity exercises, such as running or high-intensity interval training (HIIT), can burn more calories compared to lower intensity exercises like walking.
In addition, it is important to recalculate the energy expenditure when the client loses weight. As weight loss occurs, the total energy expenditure decreases. Therefore, it is necessary to adjust the clients' energy intake and activity level accordingly to continue achieving weight loss or maintaining a healthy weight.
While the total distance or time of walking or running can contribute to the energy expenditure, it is the intensity of the aerobic activity that has a larger impact on total energy expenditure. It is also crucial to consider the resting energy expenditure of the client as it contributes to the total energy expenditure throughout the day, even during periods of rest.
