The number of calories you’ll burn during exercise depends on your size, exercise intensity and type of physical activity you’re performing. Certain forms of exercise will help you burn more calories in a shorter time. If you’re overweight or obese, burning an additional 500 to 1,000 calories per day can help you lose about 1 to 2 Ibs. of body weight per week, if your calorie intake remains unchanged.
Cardiac output varies among adults who are highly adapted to exercise and people not in condition. The output also is influenced by age, gender and what sort of exercise you are doing. Cardiac output is interdependent with blo...
