Body Mass Index

The Body Mass Index - BMI

The index of body mass can also be called the Quetelet index. It is a measurement of statistics which compares an individual in size and weight. It's a great tool for estimating a healthy body mass based on the height of an individual. It is. It's accurate and is the most frequently used tool for identifying the weight issue.

Criteria For Underweight And Obesity By BMI

Now with the help of the World Health Organisation (WHO) criteria for underweight and obesity through BMI, you may come to determine if the person falls under the categories of overweight, obese overweight or falls into the category of obesity.

Calculation Of BMI

BMI of any individual is determined by using the following formula: Body Mass Index (BMI) = Body mass (weight x height) (height + height)
Here the weight of the person weighs in kilograms. the height is measured in meters.
Example:
If the body mass of an individual is 70 kg and his/her height is 1.60 m. Now , compute these values.
BMI = 70 / (1.60 x 1.60) = 70 / 2.56 = 27.34 kg/m2
Today, with the help of the World Health Organisation (WHO) criteria for underweight and obesity
By BMI, you may come to discover if the individual is classified as overweight, normal
the overweight, weight or falls into the category of overweight.

Precautions During Measurements

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

1. The body's weight needs to be carried out on the most reliable and accurate weight machine.
2. The student, whose body weight is to be recorded, must wear the minimum of required clothing without shoes.
3. In order to measure height the student should be bare-footed 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 that is used to judge and evaluate the level of fitness of the youth. The first version of this test was released in 1958, then updated in 1966 and later in 1976. Many modifications to the test's test battery were implemented in the year 1976 for the AAPHER youth fitness test. This test is intended to measure the fitness levels of youngsters. The tests assess body composition, flexibility, agility, coordination, upper body strength, and aerobic endurance. The tests are constructed so that they can be administered by professionals in the field.

Here are the test components from 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 minutes run from ages 10-12 years old. 1.5 mile and 12 minutes run for kids 13 and over.

In the year 1980, AAPHERD introduced the "Physical Best" test which included the following items:
1. 1 1/2 mile walk run or 12-minute run
2. Skin fold measurement body fat
3. Sit ups
4. Pull ups
5. Sit and then reach the test

The test of physical fitness awards students according to their physical fitness in the above tests.

Shuttle Run

This test measures speed, speed and agility of the participants. Create two parallel lines that are 30 feet apart. Place two wood blocks between the two lines. Students start on the parallel line. On the signal 'Go' the student runs to the blocks , selects one up, walks back to the line from which they started, puts the block behind the line, returns and then picks up the next block before running back to the starting line. Blocks must be placed within the lines.

Pull-Ups Testing

Student hangs from a horizontal bar that the student is able to be hung from, arms fully extended and feet free from ground using either an grip or an underhand. Students who are short in height can be lifted to a starting position. They raise body until that the bar is cleared of chin and then lower
body until it is fully in the hang body to full hang starting. Student performs as many correct pull-ups as he is able to.

Flexed- Arm Hang Testing

By using an overhand or an underhand grip, the student will be in a flexed hang posture with their chin clear of the bar. Students may be lifted into this position. Student holds this position until he is able to.

Flexed Arm Hang Scoring

The chest of the student should be kept close to the bar, with the legs straight. The measurement of time stops when the student's neck touches or is lowered below the bar.

Standing Long Jump

The standing long jump is a popular and simple test to conduct to test the power of your legs. The athlete stands in front of a line marked on the ground. With the feet set slightly apart. A two-foot take-off and landing is performed using swinging of the arms , and then bending knees to create the forward drive. The student will attempt to jump as far as possible landing on both feet without falling backwards. Three attempts are permitted. The measurement is calculated from the where the take-off line is located to the closest point of contact upon landing the distance that is the longest jumped in three attempts. The best three times are 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 completed, the duration spent to complete the 50-yard distance is noted.

The new test developed by AAPHERD seeks to determine 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 acceptable, students are then asked in 12 mins of running. This method is where their distance is measured. The first method is thought to be the best way to know the cardiovascular fitness.

2. Skin Fold Measurement:

The calipers' skin is used to measure the fat thickness in various parts of the body After checking the thickness of various parts of the body, these measurements are put in one equation (different equation for males and females) in order to calculate the density of the body. After calculating the body's density, it is put in equations to calculate the percentage of body fat. All the measurements must be done by examining the back of the body.
The following three parts are weighed:
(a) The skin fold around the abdominal region
(b) Chest skinfold
(c) Arm skinfold
