Body mass index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms (kg) and height in metres (m).
Abdominal obesity, also known as central obesity and truncal obesity, is the human condition of an excessive concentration of visceral fat around the stomach and abdomen to such an extent that it is likely to harm its bearer's health. Abdominal obesity has been strongly linked to cardiovascular disease, Alzheimer's disease, and other metabolic and vascular diseases.
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest along with a formal recovery plan.
The waist is the part of the abdomen between the rib cage and hips. On people with slim bodies, the waist is the narrowest part of the torso.
The joint European standard for size labelling of clothes, formally known as the EN 13402 Size designation of clothes, is a European standard for labelling clothes sizes. The standard is based on body dimensions measured in centimetres, and as such, and its aim is to make it easier for people to find clothes in sizes that fit them.
The anthropometry of the upper arm is a set of measurements of the shape of the upper arms.
The waist–hip ratio or waist-to-hip ratio (WHR) is the dimensionless ratio of the circumference of the waist to that of the hips. This is calculated as waist measurement divided by hip measurement. For example, a person with a 75 cm waist and 95 cm hips has WHR of about 0.79.
The body fat percentage (BFP) of a human or other living being is the total mass of fat divided by total body mass, multiplied by 100; body fat includes essential body fat and storage body fat. Essential body fat is necessary to maintain life and reproductive functions. The percentage of essential body fat for women is greater than that for men, due to the demands of childbearing and other hormonal functions. Storage body fat consists of fat accumulation in adipose tissue, part of which protects internal organs in the chest and abdomen. A number of methods are available for determining body fat percentage, such as measurement with calipers or through the use of bioelectrical impedance analysis.
In physical fitness, body composition refers to quantifying the different components of a human body. The selection of compartments varies by model but may include fat, bone, water, and muscle. Two people of the same gender, height, and body weight may have completely different body types as a consequence of having different body compositions. This may be explained by a person having low or high body fat, dense muscles, or big bones.
U.S. standard clothing sizes for women were originally developed from statistical data in the 1940s and 1950s. At that time, they were similar in concept to the EN 13402 European clothing size standard, although individual manufacturers have always deviated from them, sometimes significantly.
The Army Physical Fitness Test (APFT) was designed to test the muscular strength, endurance, and cardiovascular respiratory fitness of soldiers in the United States Army. Soldiers were scored based on their performance in three events consisting of the push-up, sit-up, and a two-mile run, ranging from 0 to 100 points in each event. A minimum score of 60 in each event was required to pass the test. The soldier's overall score was the sum of the points from the three events. If a soldier passed all three events, the total could have range from 180 to 300.
Human body shape is a complex phenomenon with sophisticated detail and function. The general shape or figure of a person is defined mainly by the molding of skeletal structures, as well as the distribution of muscles and fat. Skeletal structure grows and changes only up to the point at which a human reaches adulthood and remains essentially the same for the rest of their life. Growth is usually completed between the ages of 13 and 18, at which time the epiphyseal plates of long bones close, allowing no further growth.
The Leadership Development and Assessment Course is the centerpiece of the US Army's Reserve Officers' Training Corps (ROTC) program. Since the 1950s, the Army has called it "Advanced Camp"; it is currently known as "Warrior Forge". It is conducted during June, July, and August at Fort Knox, Kentucky. The course is normally attended by cadets between their junior and senior years of college, although the last rotation consists of soldiers in the Officer Candidate School as well as military junior colleges.
The Indoor Obstacle Course Test (IOCT) is a test of full-body functional physical fitness administered by the Department of Physical Education (DPE) at the United States Military Academy at West Point, New York. DPE considers the IOCT to be one of the best evaluations of total body fitness given in the Army. Cadets who earn an A− are authorized to wear the IOCT Badge on their athletic shorts.
Female body shape or female figure is the cumulative product of a woman's bone structure along with the distribution of muscle and fat on the body.
Obesity classification is a ranking of obesity, the medical condition in which excess body fat has accumulated to the extent that it has an adverse effect on health. The World Health Organization (WHO) classifies obesity by body mass index (BMI). BMI is further evaluated in terms of fat distribution via the waist–hip ratio and total cardiovascular risk factors. In children, a healthy weight varies with age and sex, and obesity determination is in relation to a historical normal group.
The Army Reserve Officer Training Corps (AROTC) is the United States Army component of the Reserve Officers' Training Corps. It is the largest Reserve Officer Training Corps (ROTC) program which is a group of college and university-based officer training programs for training commissioned officers for the United States Army and its reserves components: the Army Reserves and the Army National Guard. There are over 30,000 Army ROTC cadets enrolled in 274 ROTC programs at major universities throughout the United States. These schools are categorized as Military Colleges (MC), Military Junior Colleges (MJC) and Civilian Colleges (CC).
A Body Shape Index (ABSI) or simply body shape index (BSI) is a metric for assessing the health implications of a given human body height, mass and waist circumference (WC). The inclusion of WC is believed to make the BSI a better indicator of risk of mortality from excess weight than the standard body mass index. ABSI correlates only slightly with height, weight and BMI, indicating that it is independent of other anthropometric variables in predicting mortality.
The United States Army Combat Fitness Test (ACFT) is the fitness test for the United States Army. It was designed to better reflect the stresses of a combat environment, to address the poor physical fitness of recruits, and to reduce the risk of musculoskeletal injuries for service members. It consists of six events. Each event is graded on a scale from 0 to 100 points. A minimum of 60 points is required to pass each event. The maximum score is a 600. The test is the US Army's fitness test of record since October 2022.
