All of the following are factors likely to affect energy expenditure during exercise EXCEPT: A. fitness level of individual B. duration of the exercise period C. consumption of multi-vitamin supplements D. muscle mass used while exercising

The factor that does NOT AFFECT the energy expenditure during exercise is the consumption of multivitamin supplements (Option C).

Physical exercise refers to the performance of some physical activity to develop and/or maintain fitness and health.

Physical activity accounts for approximately 30% to 40% of the total energy expenditure during a day.

Vitamins and minerals are essential micronutrients but they have no calories and therefore do not affect the energy expenditure during exercise.

In conclusion, the factor that does NOT AFFECT the energy expenditure during exercise is the consumption of multivitamin supplements (Option C).

C. consumption of multi-vitamin supplements

Explanation:

Consumption of multivitamin supplements can’t affect energy expenditure during exercises because multivitamins are substances ingested to help boost the body’s metabolism.

Fitness levels of individuals would determine how long the person would exercise. If fitness levels are high the individual will expend more energy before getting tired and if low won’t expend much energy.

Duration of the exercise is also a factor. The higher the duration the more energy expended and the Lower the duration the less energy expended.

Some types of muscle mass supports more energy expenditure than others.
