!!! Energy Intake, Expenditure and Balance in Physical Activity and Performance

Question 1

What is energy?

Answer 1

The strength required for sustained physical or mental activity.

Question 2

What is energy expenditure?

Answer 2

The sum of the basal metabolic rate, the thermic effect of food and the energy expended in physical activity.

Question 3

What is basal metabolic rate?

Answer 3

Basal metabolic rate (BMR): The minimum amount of energy to sustain essential physiological function.

Question 4

What is the thermic effect of food?

Answer 4

Thermic effect of food (TEF)- Is the amount of energy it takes to eat, digest, absorb and use food taken in.

Question 5

What is physical activity energy expenditure?

Answer 5

The energy expended during body movement. Calculated by multiplying MET by BMR.

Question 6

What is metabolic equivalent (MET)?

Answer 6

The caloric consumption of an active individual compared with the resting basal metabolic rate at rest.

Question 7

What happens if someone does not eat enough calories?

Answer 7

1. Muscle loss
2. Decreased intensity and duration of performance
3. Increased risk of injury, fatigue and illness.

Question 8

What equation must be remembered?

Answer 8

Energy expenditure = BMR + TEF + physical activity energy expenditure.

Question 9

Why is it important for an athlete to calculate energy expenditure?

Answer 9

1. Can calculate the overall energy cost of a training session
2. Can adjust diet according to the number of calories burned.
3. It estimates the energy cost of an activity to the amount of oxygen consumed.
