Principles of Inheritance and Variation.New Questions and Answers and Forum Categories (Lean tissue is more metabolically demanding than fat tissue.) So more calories are burnt even when sleeping. Physical exercise not only influences body weight by burning calories, it also helps raise the BMR by building extra lean tissue. Both these factors tend to increase the metabolic rate. Anxiety and tension may not show on the face but they do produce an increased tensing of the muscles and release of norepinephrine even though the subject is seemingly quiet. Like thyroxine, adrenaline also increases the BMR but to a lesser extent. If too little thyroxine is produced (myxoedema) BMR may shrink to 30-40 percent of normal rate. If too much thyroxine is produced (thyrotoxicosis) BMR can actually double. The more thyroxine produced, the higher the BMR. Thyroxine is a key BMR-regulator which speeds up the metabolic activity of the body. But prolonged exposure to heat can raise BMR. A short exposure to hot temperature has little effect on the body’s metabolism as it is compensated mainly by increased heat loss. Exposure to cold temperature causes an increase in the BMR, so as to create the extra heat needed to maintain the body’s internal temperature. Temperature outside the body also affects basal metabolic rate. although the BMR of a man as given above is higher than that of a boy of 15 kg body weight that spends about 800 Kcal/day for its basal metabolism, the BMR per kg/day of man is about 30 Kcal, while that of the boy is about 53 Kcal/kg/day. Heavily built persons have higher BMRs, but the BMR per unit body weight is higher in the smaller built individuals ex. In terms of oxygen consumption it would amount to about 15 litre/hr. of an average Indian man is 1750-1900 Kcal/day.
It is essentially the minimum energy required to maintain the heart rate, respiration, kidney function etc. in a room with comfortable temperature and humidity, awake and sitting in a reclining position, 10-12 hours after the last meal. Definition of BMR:īasal metabolic rate is the energy released when the subject is at complete mental and physical rest i.e. After reading this article you will learn about 1. Let us make an in-depth study of the basal metabolic rate (BMR).
