Calculate your fitness.
Basal Metabolic Rate or simply BMR is the minimal amount of energy you expend when you are at rest. For an accurate BMR calculation, a specific set of criteria should be strictly met. A proper measurement requires that the body be in complete rest, preferably in the post- absorptive state, that is, when the digestive system is inactive. The energy released then is required only for the functioning of the most vital organs, namely the heart, lungs, brain and the entire nervous system, liver, kidneys, sex organs, muscles and skin. Age, gender, height and weight are essential to calculate BMR. Other factors that can affect one's BMR include lean body mass, nutrition and diet, lifestyle and medical considerations.Equations
A more common measurement, which uses fewer criterions, is Resting Metabolic Rate (RMR). Gympik.com provides you with this BMR calculating tool based on the popularly used Harris- Benedict Equation and is available in both imperial and metric units. The equation is demonstrated below:
Imperial System : BMR = (6.25 x WP) + (12.7 x HI) - (6.76 x age) + 66
Metric System : BMR = (13.75 x WKG) + (5 x HC) - (6.76 x age) + 66
Imperial System : BMR = (4.35 x WP) + (4.7 x HI) - (4.68 x age) + 655
Metric System : BMR = (9.56 x WKG) + (1.85 x HC) - (4.68 x age) + 655
