Body Mass Index

The Body Mass Index - BMI

The Body Mass Index is also known as also the Quetelet index. It is a statistical measurement that compares an individual's weight and height. It's a useful tool to estimate a healthy body weight . The measurement based on the height of an individual. It is accurate, and it is most widely used tool for identifying the weight issue.

Criteria For Underweight And Obesity By BMI

With the aid of The World Health Organisation (WHO) guidelines for obesity and underweight by BMI, you may come to know if this person falls under the categories of overweight, underweight, overweight or falls in the category of obese.

Calculation Of BMI

BMI of any individual is calculated by using the following formula: Body Mass Index (BMI) = Body mass (weight x height) (height in relation to height)
The weight of an individual weighs in kilograms and the height is taken in metres.
Example:
Consider that the weight of an individual is 70kg, and his height is 1.60 meters. Now compute these values.
BMI = 70 / (1.60 x 1.60) = 70 / 2.56 = 27.34 kg/m2
Today, with the help of criteria from World Health Organisation (WHO) criteria for overweight and underweight
By BMI by BMI to learn if the person is under the category of normal, overweight, or
the overweight, weight or falls under the category of overweight.

Precautions During Measurements

The following precautions must be observed while taking measurements to determine BMI.

1. The body's weight needs to be weighed using an exact and reliable weight machine.
2. The student, whose body weight is to be recorded, must wear the minimum of required clothing without shoes.
3. For the purpose of measuring height the student must be standing barefooted and their entire body must be straight.

Physical Fitness Test (AAPHERD Test Score)

AAPHERD i.e. American Alliance for Health, Physical Education, Recreation and Dance is a test to determine and assess the fitness levels of children. The first version of the test was released in 1958, and was revised in 1966 , and then in 1976. Numerous changes to the test battery were made in 1976 in AAPHER youth fitness test. The test was designed to measure the fitness levels of the young people. The tests measure body composition and flexibility, agility, coordination, upper body strength, and endurance for aerobics. The tests are designed in a way that they could be administered by experts working 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 sprint, 9 minute run for children aged 10-12 years, and 1.5 mile and 12 minutes run for kids 13 and above.

In 1980 AAPHERD introduced the 'Physical Best' test that contained the following questions:
1. 1 1/2 mile walk run 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 test of physical fitness awards students for their fitness in the above tests.

Shuttle Run

The test measures speed the speed, quickness, and agility of the students. Draw two parallel lines 30 feet apart and place two blocks of wood, between the two lines. Students begin on the parallel line. When the signal "Go" is given, the student runs to the blocks , takes one up, runs back to the starting line, places block behind the line, is back and takes the next block before running back to the starting line. Blocks should be placed between the lines.

Pull-Ups Testing

Student hangs from a horizontal bar that the student can reach with arms fully extended, and feet free from flooring using either an overhand grip or an underhand. Students with short height may be lifted to a starting position. They lift their body until their that the bar is cleared of chin and then lower
body to full hang starting body to full hang starting. Student does as many proper pull-ups as he is able to.

Flexed- Arm Hang Testing

In either an overhand or an underhand grip, the student assumes flexed arm hang position with chin clearing the bar. Students can be lifted up to this position. The student is in this position for for as long as he's able.

Flexed Arm Hang Scoring

The chest of the student must be held close to bar with legs hung straight. The timer is stopped when the student's chin touches or is lowered below the bar.

Standing Long Jump

Standing long leaps are a popular and simple test to administer test of the power of your legs. The student stands behind an imaginary line that is marked on ground. With feet slightly apart. Two-foot take-off and landing is performed using swinging of the arms and bending of the knees to give forward thrust. The student attempts to jump at the highest level possible and land on both feet while not falling backwards. Three attempts are allowed. The measurement is calculated from the starting point to the closest point of contact at landing the longest distance covered in 3 attempts. The highest score is recorded.

50-Yard Dash

This is a test used to test the speed of a student. The participant stands in front of the starting line , and begins running when the signal says 'Go'. As soon as the distance has been covered, the amount of time it took to complete 50 yards is recorded.

The latest test from AAPHERD attempts to assess the fitness of health

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

Students are expected to run 1.5 mile. Their timings are taken by stop watch. If this method isn't adequate, students are instructed in 12 mins of running. The distance is noted down. The first method is considered to be the best method to assess the cardiovascular fitness.

2. Skin Fold Measurement:

In this test , the calipers's skin are used to measure what the amount of fat on various body parts. After taking measurements of the thickness of various parts of the body, these results are then put into one equation (different equation for girls and boys) for calculate the body density. After calculating the body's density, it is then put into an equation to calculate the percentage of body fat. All measurements should be taken using the right-hand side.
The three parts that follow are measured:
(a) Skinfolds of the abdomen
(b) Chest skinfold
(c) Arm skinfold
