Body Mass Index

The Body Mass Index - BMI

The body mass index can also be known as the Quetelet index. It is a measure of statistical significance that compares a person's the areas of height and weight. It's a helpful tool to calculate the healthy body weight . Based on how tall an individual is. It is reliable and is most widely used tool to find the issue with weight.

Criteria For Underweight And Obesity By BMI

With the aid of an understanding of the World Health Organisation (WHO) guidelines for overweight and underweight through BMI You will be able to know whether this individual falls under the categories of overweight, obese overweight or falls in the category of obesity.

Calculation Of BMI

BMI of any person is determined using the following formula:Body Mass Index (BMI) = Body mass / (height and height)
The weight of the person weighs in kilograms and the height is calculated in metres.
Example:
Imagine that a person's body weight is 70kg, and his height is 1.60 meters. Now calculate these numbers.
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) guidelines for obesity and underweight
by BMI by BMI, you will be able to find out if this person is under the category of underweight, normal
the overweight, weight or falls within the category of obesity.

Precautions During Measurements

These precautions should be taken while taking the measurements to determine BMI.

1. The weight of the body must be carried out on an accurate and reliable weigh machine.
2. The student who's body weight is to be taken, must wear the minimum amount of clothes required, without shoes.
3. During the measurement of height the student should stand barefooted and the entire body should be straight.

Physical Fitness Test (AAPHERD Test Score)

AAPHERD i.e. American Alliance for Health, Physical Education, Recreation and Dance is a test that is used to measure and evaluate level of fitness of the youth. The first version of this test was made public in the year 1958, then updated in 1966 and after that in 1976. A variety of modifications to the test's batteries were made in 1976 , in the AAPHER's youth fitness test. This test is designed to measure the fitness levels of the young people. The tests measure body composition and flexibility, agility, coordination, upper body strength, and aerobic endurance. They are designed to ensure that they can be administered by experts working in the field.

Below are the test component that comprise The AAPHERD exercise test

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 suitable for ages 10 to 12 years and 1.5 mile , or 12 minutes run for children age 13 and above.

In 1980 AAPHERD introduced the 'Physical Best' test which included the following items:
1. 1 1/2 mile walk run or 12-minute run
2. The measurement of the folds on the skin is body fat
3. Sit ups
4. Pull ups
5. Sit and reach test

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

Shuttle Run

This contest measures speed, quickness and agility of the participants. Create two parallel lines that are 30 feet apart. They then put two blocks of wood, in front of the line. Students begin on the parallel line. After the signal "Go", the student races through the blocks, picks one, then runs back to the starting line, then places the block in the middle of the line, comes back and grabs the second block , and then runs across the starting line. Blocks must be placed within the lines.

Pull-Ups Testing

The student hangs from the horizontal bar that the student is able to hang from, with arms fully extended and feet free from floors using either an grip or a grip under the hand. Students who are short in height can be lifted to a starting position. They lift their body until their it is clear of the bar. They then lower.
body until it is fully in the hang position. Student performs as many correct push-ups as possible.

Flexed- Arm Hang Testing

In either an overhand or an underhand grip, the student takes flexed arms hang posture with their chin clear of the bar. Students can be lifted up to this position. The student is in this position for until he is able to.

Flexed Arm Hang Scoring

Student's chest should be held close to bar with legs straight. The duration of the timer will be stopped when student's chin touches or falls beneath the bar.

Standing Long Jump

It is a very frequent and easy test that tests the power of your legs. The athlete stands in front of one of the lines marked on the ground. With their feet slightly separated. Two-foot take-off and landing is achieved by swinging the arms and bending of the knees in order to provide forward thrust. The participant tries to leap at the highest level possible and land on both feet, but not falling backwards. Three attempts are allowed. The measurement is taken from take-off line to the nearest point of contact upon landing the greatest distance jumped in best of three attempts is recorded.

50-Yard Dash

It is a test to measure the speed of the student. The participant stands in front of the starting line and begins sprinting on the signal "Go'. Once the distance is completed, the time it took to complete 50 yards is noted.

The new test developed by AAPHERD will attempt to measure the fitness of health:

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

Students are expected to run 1.5 miles. Their time is recorded using a stop watches. If this method isn't sufficient, the students are told be on the track for 12 minutes. This way, their distance is recorded. This is the first method that is considered to be the best method to determine the fitness of the heart.

2. Skin Fold Measurement:

The calipers' skin is used for measuring the thickness of fat on various areas of the body. After taking measurements of the thickness of various organs, the measurements are put in one equation (different equation for girls and boys) so that you can calculate the density of the body. After calculating body density, it is then put in equation to calculate the percentage of fat in the body. All the measurements must be done on the right side of the body.
The three parts that follow are measured:
(a) Skinfolds of the abdomen
(b) Chest skinfold
(c) Arm skinfold
