Ever wondered what activities burn the most kilojoules?
You know you should exercise if you want to lose weight, but why is exercise so important? Is it simply because you burn energy whilst exercising?
No, it is about so much more than what happens during your workout. When you exercise, you increase your muscle percentage. Your muscle cells use fat as their source of energy. Therefore, the higher a person’s muscle percentage, the more fat her body burns, even though she is in a resting position. But for interest’s sake, I have listed below more or less how many kilojoules you burn during specific activities.
To lose half a kilogram per week, you should burn about 15 000 kilojoules more than usual. The amount of kilojoules burned during an activity depends on how much you weigh. A person weighing 50kg will burn less kilojoules during a specific activity than a person weighing 80kg doing that same activity. A good way to burn extra kilojoules is to extend the duration of your workouts or to exercise at a higher intensity.
The table below gives an indication of how many kilojoules (kJ) a person weighing 70 kg burns:
|Cycling @ 20 km per hour||1700 kJ per hour|
|Jogging @ 9 km per hour||3000 kJ per hour|
|Skipping rope||3100 kJ per hour|
|Swimming @ 45m per minute||2000 kJ per hour|
|Walking @ 7.5 km per hour||1800 kJ per hour|
|Playing Tennis (singles)||1700 kJ per hour|
