![]() Supplement intake and dosage may be governed by the resting metabolic rate as well. This is also the general application of a Resting Metabolic Rate calculator: calculating metabolism needs, fitness regimen energy requirements, athletes food intake for competitive sports, and so on. Abbreviations aside, RMR is a huge component of Total Daily Energy Expenditure (TDEE) - usually 60-85% of TDEE and is often used to calculate daily caloric needs, and from them: different kinds of diets / food regimes, and nutrient requirements. It is also encountered under the names Resting Energy Expenditure or REE, as well as RDEE - Resting Daily Energy Expenditure, which is why this tool can be referred to as both an RMR calculator, REE calculator, or RDEE calculator. The Resting Metabolic Rate (RMR) is the amount of energy your body consumes when in resting state. RMR metrics used: 1 Calorie = 1 kcal (1 kilocalorie) = 1,000 calories. How accurate are RMR / REE estimations?.RMR formula and calculating your Resting Metabolic Rate.Take this into account when interpreting the data. It should be noted that the mean and the median values, at least for children and adolescents of age 0-20 differ significantly, with the median being significantly lower than the mean, suggesting that the distribution is affected by a relatively small number of overweight and obese individuals. ![]() Mean female BSA by age table: Mean (average) BSA for males by age Age or age groupīody surface area in squared meters and squared feet in the graph and tables is calculated using our body surface area calculator. Mean male BSA by age table: Mean (average) BSA for males by age Age or age group The graph clearly shows that values for boys and girls are almost identical up to 14 years of age, when they significantly departure with males having a mean BSA 10-15% higher than females due to differences in stature and weight (there is no gender component in the formula). ![]() NCHS National Health and Nutrition Examination Survey (2011-2014). īoth the chart and the tables with average body surface area estimates are based on weight and height data from the U.S. Breitmann in 1932, Stevenson in 1937, Haycock in 1978, Schlich in 2010) and a discussion about their accuracy is ongoing in the medical community, but the formula used in our BSA calculator is one of the most-commonly used by medical practitioners. There are other competing formulae derived over the years (e.g. The DuBois & DuBois original formula is:Ġ.007184 x height (cm) 0.725 x mass (kg) 0.425 This is a slight variation of the DuBois & DuBois body surface area formula, derived in 1916, modified for easier calculation with height expressed in meters instead of centimeters and the results are practically identical. Below are some average values for different age groups in graph and table form. The result is in squared meters, which easily be converted to square feet, inches or yards as needed. Where height is in meters and mass is in kg. To estimate your body surface area our BSA calculator uses the following formula :Ġ.20247 x height (m) 0.725 x mass (kg) 0.425 BSA calculations are useful when determining different body characteristics, for example energy expenditure in the form of BMR, RMR (REE), RDEE, TDEE, which are in turn used when determining dietary and nutritional needs. After removing the pieces, they were cut into regular shapes allowing accurate BSA calculation.įrom these studies we have understanding of the relationship between height (stature) and body weight (mass) and a formula through which we can calculate a persons body surface area based in their weight and height. To address it, scientists in the early 1900s took measurements via melted paraffin and paper strips applied to their body. Since the body is a complex figure, making an accurate measurement of its surface is a considerable challenge. Body Surface Area (BSA) is simply a measurement of the surface area of your body.
