Metabolic rate may be defined as the amount of energy consumed by the organism with per unit time. Around 20% of the energy of humans can be obtained through physical activity.
The estimation of oxygen consumption of body helps an individual to find the metabolic rate of the individual. The metabolic rate can be estimated as the amount of the oxygen consumed in the body and heat produced are directly proportional to each other. The graph drawn between the heat produced and body weight is used to estimate the metabolic rate.
