Download scientific diagram | Relationship between resting metabolic rate (RMR ) and fat-free mass (FFM) for 42 Caucasian (open symbols) and 40 Polynesian. Relationship between resting metabolic rate and the composition of the FFM and fat mass explained 83% of the variability in RMR (standard error of the .

Support for this hypothesis comes from the fact that mammals with larger body size have longer maximum life spans (large . "Relationship between maximum aerobic power and resting metabolic rate in young adult women".

The breakdown of large molecules into smaller molecules—associated with release of energy—is catabolism. The building up process is termed anabolism.

The breakdown of proteins into amino acids is an example of catabolism, while the formation of proteins from amino acids is an anabolic process.

Basal metabolic rate

Exergonic reactions are energy-releasing reactions and are generally catabolic. Endergonic reactions require energy and include anabolic reactions and the contraction of muscle. Metabolism is the total of all catabolic, exergonic, anabolic, endergonic reactions. Adenosine Triphosphate ATP is the intermediate molecule that drives the exergonic transfer of energy to switch to endergonic anabolic reactions used in muscle contraction. This is what causes muscles to work which can require a breakdown, and also to build in the rest period, which occurs during the strengthening phase associated with muscular contraction.

ATP is composed of adenine, a nitrogen containing base, ribose, a five carbon sugar collectively called adenosineand three phosphate groups.

ATP is a high energy molecule because it stores large amounts of energy in the chemical bonds of the two terminal phosphate groups. The breaking of these chemical bonds in the Krebs Cycle provides the energy needed for muscular contraction. Glucose[ edit ] Because the ratio of hydrogen to oxygen atoms in all carbohydrates is always the same as that in water—that is, 2 to 1—all of the oxygen consumed by the cells is used to oxidize the carbon in the carbohydrate molecule to form carbon dioxide.

Relationship of resting metabolic rate to body composition and protein turnover.

Consequently, during the complete oxidation of a glucose molecule, six molecules of carbon dioxide and six molecules of water are produced and six molecules of oxygen are consumed. The overall equation for this reaction is: When listed on nutritional information tables, fats are generally divided into six categories: From a basal metabolic or resting metabolic perspective, more energy is needed to burn a saturated fatty acid than an unsaturated fatty acid.

The fatty acid molecule is broken down and categorized based on the number of carbon atoms in its molecular structure. The chemical equation for metabolism of the twelve to sixteen carbon atoms in a saturated fatty acid molecule shows the difference between metabolism of carbohydrates and fatty acids.

Palmitic acid is a commonly studied example of the saturated fatty acid molecule. The overall equation for the substrate utilization of palmitic acid is: Unlike fat the body has no storage deposits of protein. All of it is contained in the body as important parts of tissues, blood hormones, and enzymes.

The structural components of the body that contain these amino acids are continually undergoing a process of breakdown and replacement.

The respiratory quotient for protein metabolism can be demonstrated by the chemical equation for oxidation of albumin: This process could severely degrade the protein structures needed to maintain survival such as contractile properties of proteins in the heart, cellular mitochondria, myoglobin storage, and metabolic enzymes within muscles.

The oxidative system aerobic is the primary source of ATP supplied to the body at rest and during low intensity activities and uses primarily carbohydrates and fats as substrates. Protein is not normally metabolized significantly, except during long term starvation and long bouts of exercise greater than 90 minutes.

Relationship of resting metabolic rate to body composition and protein turnover.

Following the onset of activity, as the intensity of the exercise increases, there is a shift in substrate preference from fats to carbohydrates. Both studies find that aerobic fitness levels do not improve the predictive power of fat free mass for resting metabolic rate.

However recent research from the Journal of Applied Physiology, published in Sep. Applying Your BMR Calculation to Weight Loss Once you know your BMR and the number of calories you burn for your activity level, you can improve your weight-loss efforts by setting a lower daily caloric-intake limit and crafting a plan for increasing your physical activity.

Set your daily calorie limit. Putting yourself in a calorie deficit every day should result in the loss of one pound every week, Greaves says. Adjust your exercise output. Calculators ask for your level of physical activity for a very good reason.

You can influence your BMR through exercise, spurring your body to burn more calories even when you are just lounging about. Aerobic exercise provides a temporary boost to your BMR, an effect sometimes referred to as after-burn or excess post-exercise oxygen consumption, says Noelle Lusardi, a certified personal fitness trainer who also works at the Step Ahead Weight Loss Center in Bedminster, N.

This boost drops dramatically following an aerobic workout, with your BMR returning back to its normal level within 15 minutes to 48 hours. Strength training provides a more lasting boost to BMR by altering your body's composition. Muscle at rest burns more calories than fat at rest. That's why men naturally enjoy a higher BMR than women, as they tend to have more muscle mass, Greaves explains. Increase the calorie deficit by adding more exercise.

You can also increase the intensity of your workouts to burn more calories, and you will increase your calorie deficit and aid your efforts at weight loss.
