The amount of calories you will burn while jumping is calculated based on your weight and the amount of time you spend jumping. Jumping rope will burn more calories than jumping jacks.
The formula for estimating calories burned while jumping is (METs x 3.5 x weight in kilograms) ÷ 200) x amount of time in minutes. MET, or metabolic equivalent, is calculated based on your resting metabolic rate and the energy exerted while jumping. To change your weight from pounds to kilograms, divide your weight in pounds by 2.2. A 155-pound person weighs 70 kilograms.
Jumping jacks has a MET value of 8.0. Jumping rope quickly has a MET value of 12. The high jump and long jump, while running a track and field race, has a MET value of 6.0.
A 155-pound person jumping rope at a moderate to quick pace for five minutes will burn from 59 to 70 calories. That same 155-pound person will burn 21 calories jumping on the trampoline for five minutes. Doing jumping jacks for two minutes will burn 18 calories, regardless of how many jumping jacks you do.
