Question

multiple choice question
aerobic exercise aids in weight control by:
increasing overall energy expenditure
improving flexibility
increasing fat - free mass
reducing metabolic rate during exercise

Explanation:

Aerobic exercise burns calories, which increases overall energy expenditure. This helps in weight - control as a calorie deficit is created. Flexibility improvement is not directly related to weight control. Increasing fat - free mass is more related to strength training. Reducing metabolic rate during exercise would be counterproductive for weight control.

Answer:

increasing overall energy expenditure
