Body Mass Index

The Body Mass Index - BMI

The index of body mass is also called the Quetelet index. It is a statistical measurement that compares an individual's size and weight. It's a helpful tool to estimate a healthy body weight based on how tall an individual is. It's reliable, and is the most commonly used tool for identifying the weight issue.

Criteria For Underweight And Obesity By BMI

Today, using the World Health Organisation (WHO) criteria for underweight and obesity by BMI, you may come to know if this person falls within the categories of underweight, average weight overweight or falls into the category of obese.

Calculation Of BMI

BMI for any individual is determined by using the following formula: Body Mass Index (BMI) = Body weight / (height + height)
The weight of the individual can be measured as kilograms. the height is measured in metres.
Example:
Let's say that an individual's body weight is 70 kilograms and their height is 1.60 meters. Then, calculate these figures.
BMI = 70 / (1.60 x 1.60) = 70 / 2.56 = 27.34 kg/m2
The time has come to implement guidelines from the World Health Organisation (WHO) standards for obesity and underweight
By BMI using BMI, you can come to discover if the individual falls into the category of normal or overweight.
obesity, weight, or falls under the category of overweight.

Precautions During Measurements

These precautions should be observed while taking measurements for BMI.

  1. The weight of the body must be carried out on an efficient and precise weigh machine.
  2. The student with a body mass to be measured, must wear the minimum necessary clothes without shoes.
  3. When measuring height, the student must be standing barefooted and his/her entire body needs to be straight.

Physical Fitness Test (AAPHERD Test Score)

AAPHERD i.e. American Alliance for Health, Physical Education, Recreation and Dance is a test used to examine and judge physical fitness of youngsters. The first version of this test was published in 1958. It was then revised in 1966 and later in 1976. Many changes in the test's battery were introduced during the year 1976 to the AAPHER Youth fitness test. The test was designed to assess the level of fitness of young people. The tests assess the body's composition as well as agility, flexibility, coordination as well as upper body strength and aerobic endurance. They are designed to ensure that they can be administered by professionals in the field.

Here are the test components in the AAPHERD assessment of physical strength:

  1. Pull ups (boys)
  2. Flexed-arm hang (girls)
  3. Flexed leg sit ups
  4. Shuttle run
  5. Standing broad jump
  6. 50-yard sprint, 9 minute run from ages 10-12 years. 1.5 miles or 12 minute run for children 13 and over.

In 1980 AAPHERD introduced the 'Physical Best' test that included the following elements:
1. 1 1/2 miles walk or 12-minute run
2. Body fat measurement by folds of skin
3. Sit ups
4. Pull ups
5. Sit and then reach the test

The physical fitness test recognizes students for their fitness and physical fitness during the previous activities.

Shuttle Run

This contest measures speed as well as agility the participants. Draw two parallel lines 30 feet apart and place two blocks of wood, in front of the line. Students begin at the parallel line. When the signal "Go" is given, the student runs to the blocks , selects one up, returns to the starting line, and places the block on the line, returns and then picks up the next block before running back across starting line. Blocks should be placed between the lines.

Pull-Ups Testing

A student hangs from a horizontal bar that the student is able to hang from with arms fully extended and feet free from ground using either an grip or an underhand. Students with short height may be lifted into starting position. They will raise the body until the chin clears the bar and then lower it.
body to fully hang starting position. Student performs as many correct pull-ups as he is able to.

Flexed- Arm Hang Testing

In either an overhand or an underhand grip, the student is in a flexed hanging in a position where the chin is clear of the bar. Students are able to be lifted to this position. The student is in this position for as long as he can.

Flexed Arm Hang Scoring

Student's chest should be held close to the bar, with the legs hanging straight. The measurement of time stops when the student's neck touches or falls under the bar.

Standing Long Jump

The standing long jump is a regular and straightforward test for testing the power of your legs. The test participant is placed behind a line marked on the ground. With their feet a little apart. A take-off with a two-foot landing is accomplished by swinging the arms as well as bending the knees to give the forward drive. The participant tries to leap at the highest level possible landing on both feet while not falling backwards. Three attempts are allowed. The measurement is taken from starting point to the closest point of contact at landing the greatest distance jumped in 3 attempts. The highest score is recorded.

50-Yard Dash

This is a test used to determine the speed of the student. The participant stands in front of the starting line , and begins sprinting on the signal "Go'. As soon as the distance has been covered, the amount of time required to cover 50 yards is recorded.

The new test for AAPHERD attempts to measure how healthy you are:

1. 1 1/2 Mile Walk/Run Or 12-Minute Run

Students are asked to run 1.5 mile. Their time is recorded using a stop watches. If this method is not appropriate, then the students are required be on the track for 12 minutes. In this method their distance is recorded. The first method is believed to be the best way for determining the cardio fitness.

2. Skin Fold Measurement:

In this test calipers skin is used to gauge the fat thickness on different areas of the body. After taking measurements of the thickness of various areas of the body, the measurements are then placed in one equation (different equation for males and females) for calculate the body density. After calculating the body's density, it's then placed into an equation to calculate the body fat percentage. All measurements must be done from the left side.
The following three parts are the ones that are measured:
(a) Skinfolds of the abdomen
(b) Chest skinfold
(c) Arm skinfold
