Mass and energy are closely related to each other. According to mass-energy equivalence, if any object that has mass is stationary or rest mass also has an equivalent amount of energy whose form is called rest energy. Any additional energy (of any form) acquired by the object above that re...

Of course, during vigorous exercise, the energy consumption of the skeletal muscles and heart increase markedly. About 75% of the calories burned in a day go into these basic functions. The BMR is a function of age, gender, total body weight, and amount of muscle mass (which burns more ...
