Schofield Equation
The Schofield Equation is a method of estimating the basal metabolic rate (BMR) of adult men and women published in 1985. This is the equation used by the World Health Organization, WHO in their technical report series. The equation that is recommended to estimate BMR by the US Academy of Nutrition and Dietetics is the Basal metabolic rate#BMR estimation formulas, Mifflin-St. Jeor equation. The equations for estimating Basal metabolic rate, BMR in kJ/day (kilojoules per day) from body mass (kg) are:Energy Requirements of Adults, Report of a Joint FAO/WHO/UNU Expert Consultation (See table 5.2). Men: Women: The equations for estimating BMR in kcal/day (kilocalories per day) from body mass (kg) are: Men: Women: Key: W = Body weight in kilograms SEE = Standard ...

Basal Metabolic Rate
Basal metabolic rate (BMR) is the rate of food energy, energy expenditure per unit time by endotherm, endothermic animals at rest. It is reported in energy units per unit time ranging from watt (joule/second) to ml O2/min or joule per hour per kg body mass J/(h·kg). Proper measurement requires a strict set of criteria to be met. These criteria include being in a physically and psychologically undisturbed state and being in a Thermal neutral zone, thermally neutral environment while in the post-absorptive state (i.e., not actively digesting food). In Bradymetabolism, bradymetabolic animals, such as fish and reptiles, the equivalent term standard metabolic rate (SMR) applies. It follows the same criteria as BMR, but requires the documentation of the temperature at which the metabolic rate was measured. This makes BMR a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining "standard" rates of metabolism for ma ...

Athlete
An athlete (also sportsman or sportswoman) is a person who competes in one or more sports that involve physical strength, speed, or endurance. Athletes may be professionals or amateurs. Most professional athletes have particularly well-developed physiques obtained by extensive physical training and strict exercise accompanied by a strict dietary regimen. Definitions The word "athlete" is a romanization of the el, άθλητὴς, ''athlētēs'', one who participates in a contest; from ἄθλος, ''áthlos'' or ἄθλον, ''áthlon'', a contest or feat. The primary definition of "sportsman" according to Webster's ''Third Unabridged Dictionary'' (1960) is, "a person who is active in sports: as (a): one who engages in the sports of the field and especially in hunting or fishing." Physiology Athletes involved in isotonic exercises have an increased mean left ventricular end-diastolic volume and are less likely to be depressed. Due to their strenuous physical activities, ...

Mass
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harris–Benedict Equation
The Harris–Benedict equation (also called the Harris-Benedict principle) is a method used to estimate an individual's basal metabolic rate (BMR). The estimated BMR value may be multiplied by a number that corresponds to the individual's activity level; the resulting number is the approximate daily kilocalorie intake to maintain current body weight. The Harris-Benedict equation may be used to assist weight loss — by reducing the kilocalorie intake number below the estimated maintenance intake of the equation. Calculating the Harris-Benedict BMR The original Harris–Benedict equations were published in 1918 and 1919. The Harris–Benedict equations revised by Roza and Shizgal in 1984. The 95% confidence range for men is ±213.0 kcal/day, and ±201.0 kcal/day for women. The Harris–Benedict equations revised by Mifflin and St Jeor in 1990: History The Harris-Benedict equation sprang from a study by James Arthur Harris and Francis Gano Benedict, which was published ...

United Nations University
The (UNU) is the think tank and academic arm of the United Nations. Headquartered in Shibuya, Tokyo, Japan, with diplomatic status as a UN institution, its mission is to help resolve global issues related to human development and welfare through collaborative research and education. In 1969, UN Secretary-General U Thant proposed "the establishment of a United Nations university, truly international and devoted to the Charter objectives of peace and progress". Following three annual sessions discussing the matter, the United Nations General Assembly (UNGA) approved the founding of the United Nations University in December 1972. Tokyo was chosen as the main location due to the Japanese government's commitment to provide facilities and $100 million to the UNU endowment fund. The United Nations University was formally inaugurated in January 1975 as the world's first international university. Since 2010, UNU has been authorized by the UNGA to grant postgraduate degrees, offering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Institute Of Medicine Equation
The Institute of Medicine Equation was published in September 2002. It is the equation which is behind the 2005 Dietary Guidelines for Americans and the new food pyramid, MyPyramid. The Institute of Medicine equation uses a different approach to most others. The equation doesn't measure basal metabolic rate, but uses experiments based on doubly labelled water. The scientists at the Institute of Medicine said in their report that the factorial method tended to underestimate calorie expenditure. Equations The Estimated Energy Requirement, \text, is the estimated number of daily kilocalories, or Calories, an individual requires in order to maintain his or her current weight.

Armed Forces
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mail Carrier
A mail carrier, mailman, mailwoman, postal carrier, postman, postwoman, or letter carrier (in American English), sometimes colloquially known as a postie (in Australia, Canada, New Zealand, and the United Kingdom), is an employee of a post office or postal service, who delivers mail and parcel post to residences and businesses. The term "mail carrier" came to be used as a gender-neutral substitute for "mailman" soon after women began performing the job. In the Royal Mail, the official name changed from "letter carrier" to "postman" in 1883, and "postwoman" has also been used for many years. United States In the United States, there are three types of mail carriers: City Letter Carriers, who are represented by the National Association of Letter Carriers; Rural Carriers, who are represented by the National Rural Letter Carriers' Association; and Highway Contract Route carriers, who are independent contractors. While union membership is voluntary, city carriers are organized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
