calories burnt

Question
Hi
I am Jareesh, I want to know some formula on the basis of Calories burnt on different exercises.
Such as Leg Extension mechine, cycling mechine, according to diferent person's weight.
Could you provide me with a better note on this issue.

Answer
I don't have the figures or formula close at hand to answer your question directly. However, body weight does not have a major effect on calories burned in exercises that are done in a seated position. When your body weight is not supported by your legs, calories burned are simply the energy used to overcome that resisitance.

This is why resistance exercises generally don't burn as many calories directly as weight-bearing aerobic exercises. However, resistance exercise helps build muscles which in turn "waste" energy indirectly.

It is when you get on your feet and move your entire body that your weight affects calories burned. A simple internet search (use terms such as 'calories', 'energy', and 'specific exercises') should locate a formula to answer your question.
