Body Mass Index

The Body Mass Index - BMI

Body mass index is also called"the Quetelet index. It is a measurement of statistics that compares an individual's body weight and height. It's a useful instrument to determine the healthy bodyweight based upon the height of an individual. It is. It's reliable, and is the most commonly used tool to pinpoint the problem with weight.

Criteria For Underweight And Obesity By BMI

Now with the help of this information, and the World Health Organisation (WHO) guidelines for overweight and underweight according to BMI, you may come to know if this person is classified as overweight, underweight overweight or falls within the category of obese.

Calculation Of BMI

BMI that of an person is calculated using the following formula:Body Mass Index (BMI) = Body weight (weight x height) (height in relation to height)
The weight of the individual is measured in kilograms. Likewise, the height is taken in meters.
Example:
Let's say that an individual's body weight is 70 kg and his/her height is 1.60 meters. Now compute these values.
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) the criteria for obese and overweight have been updated.
by BMI by BMI to know whether this individual falls under the category of normal or underweight.
obesity, weight, or falls in the category of obesity.

Precautions During Measurements

The following precautions must be observed when taking measurements for BMI.

  1. The body's weight should be recorded on an exact and reliable weigh machine.
  2. The student with a body mass to be measured, should wear the minimum necessary clothes without shoes.
  3. In order to measure height the student should not be wearing shoes and the body of the student must 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 the test was launched in 1958, then updated in 1966 , and then in 1976. A number of changes to the test's battery were introduced in 1976 , in the AAPHER's youth fitness test. The test was designed to test the level of fitness of youth. The tests test the body's composition as well as agility, flexibility, coordination in upper body strength and endurance for aerobics. The tests are designed in a way they can be administered by professionals on the job.

These are the components for AAPHERD physical fitness test: AAPHERD Physical fitness tests:

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

In the year 1980, AAPHERD introduced the 'Physical Best' test which included the following items:
1. 1 1/2 miles walk or 12-minute run
2. Measurement of body fat in the skin fold
3. Sit ups
4. Pull ups
5. Sit and test your reach

The physical fitness test is a way to recognize students for their physical fitness in the above events.

Shuttle Run

The test measures speed as well as agility the participants. Set two parallel lines 30 feet apart. Place two blocks of wood, in front of the line. Students start at the parallel line. After the signal "Go", the student races to the blocks picks one up, returns to the line from which they started, puts the blocks behind the line, is back and takes another block and runs back across starting line. Blocks should be placed within the lines.

Pull-Ups Testing

A student hangs from a horizontal bar at a height the student can be hung from, arms fully extended and feet off the flooring using either an overhand grip or an underhand. Students who have a short height may be lifted up to the starting position. They lift their body until their your chin is clear of the bar, then lower it.
Body is brought to full hang position. Student performs as many accurate push-ups as possible.

Flexed- Arm Hang Testing

In either an overhand or an underhand grip, the student takes flexed arms hang position with chin clearing the bar. Students are able to be lifted to this position. The student holds the position as long as he can.

Flexed Arm Hang Scoring

Student's chest should be positioned close to the bar, with the legs straight. The timer is stopped when the student's chin is in contact with or is lowered below the bar.

Standing Long Jump

The standing long jump is a frequent and easy test to administer test of explosive leg power. The participant stands in front of an imaginary line that is marked on ground. The feet are placed slightly apart. A two-foot landing and take-off is used with swinging of the arms , and then bending the knees to give forward motion. The participant tries to leap at the highest level possible and land on both feet without falling backwards. Three attempts are permitted. The measurement is taken from beginning point to point of contact on landing the longest distance covered in 3 attempts. The highest score is recorded.

50-Yard Dash

It's a test designed to determine the speed of the student. The participant stands in front of the starting line , and begins running when the signal says 'Go'. As soon as the distance is completed, the time spent to complete the 50-yard distance is recorded.

The latest test from AAPHERD attempts to measure health fitness:

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

Students are asked to run 1.5 miles. The time they run is measured using a stop watch. If this method isn't sufficient, the students are told be on the track for 12 minutes. In this method their distance is measured. The first method is considered to be the most effective method to measure the aerobic fitness.

2. Skin Fold Measurement:

The calipers' skin is used to determine how thick fat is in different parts of the body. After measuring the thickness of various organs, the measurements are then placed in one equation (different equation for boys and girls) so that you can calculate the body's density. After calculating body density, the data is placed into an equation to calculate the body fat percentage. All measurements must be done from the left side.
The following three parts are weighed:
(a) The skin fold around the abdominal region
(b) Chest skinfold
(c) Arm skinfold
