Body Mass Index

The Body Mass Index - BMI

Body mass index is also known as also the Quetelet index. It is a statistic which measures an individual's both height and weight. It's a useful tool to estimate a healthy body weight . Based on the height of an individual. It is accurate, and it is the most popular tool for identifying the weight issue.

Criteria For Underweight And Obesity By BMI

Today, using the World Health Organisation (WHO) guidelines for overweight and underweight by BMI It is possible to discover whether the individual is under the category of overweight, underweight overweight or falls into the category of obesity.

Calculation Of BMI

BMI of an individual is calculated by using the following formula: Body Mass Index (BMI) = Body weight (weight x height) (height and height)
The weight of the individual weighs in kilograms while the height is calculated in meters.
Example:
Consider that the weight of an individual is 70kg. His/her height is 1.60 m. Then, calculate these figures.
BMI = 70 / (1.60 x 1.60) = 70 / 2.56 = 27.34 kg/m2
Now , with the aid of The World Health Organisation (WHO) standards for obesity and underweight
by BMI By analyzing BMI, you are able to determine if the person is classified as normal or overweight.
obesity, weight, or falls under the category of obesity.

Precautions During Measurements

These precautions should be taken while taking the 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 with a body mass to be measured, should wear the minimum necessary clothes without shoes.
3. When measuring height, the student should be bare-footed 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 fitness test that helps assess and judge the level of fitness of the youth. The initial version of this test was announced in 1958 and then revised in the year 1966, followed by a revision in 1976. Many modifications to the test's test battery were implemented in 1976 , in the AAPHER's youth fitness test. The test was intended to measure the level of fitness of teenagers. The tests test body composition as well as agility, flexibility, coordination in upper body strength and endurance for aerobics. The tests are constructed so that they could be administered by experts in the field.

These are the components from AAPHERD physical fitness test: AAPHERD physical fitness 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 dash 9 minutes run for ages 10 to 12 years and 1.5 mile or 12 minutes run for children age 13 and up.

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

The physical fitness test recognizes students for their fitness in the above activities.

Shuttle Run

This competition measures speed, speed and agility of the participants. Draw two parallel lines 30 feet apart and place two wood blocks between the two lines. Students begin at the parallel line. 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, comes back and grabs the second block and runs across the starting line. Blocks must be placed in the lines.

Pull-Ups Testing

A student hangs from a horizontal bar that the student can reach with arms fully extended and feet off the floors using either an grip or underhand. Students with a shorter height could be lifted up to the starting position. They lift their body until their chin clears the bar and then lower.
Body is brought to full hang position. Student does as many proper pull-ups as they can.

Flexed- Arm Hang Testing

In either an overhand or underhand grip, student is in a flexed hanging and chin just above 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

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

Standing Long Jump

Standing long leaps are a common and easy test that tests the power of your legs. The student stands behind an area marked on the ground. With their feet slightly separated. A take-off with a two-foot landing is accomplished by swinging arms and bending the knees to provide forward thrust. The student will attempt to jump as far as possible by landing on both feet while not falling backwards. Three attempts are permitted. The measurement is calculated from the start line to nearest point of contact after landing the distance that is the longest jumped in the best three attempts. recorded.

50-Yard Dash

This is a test used to determine the speed of the student. The student stands at the line of start and begins going at the speed of 'Go'. When the entire distance is covered the time spent to complete the 50-yard distance is recorded.

The latest test from AAPHERD attempts to measure fitness of health

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

Students are expected to run 1.5 miles. The timings are recorded by a stop watch. If this method isn't acceptable, students are then asked to do a 12-minute run. In this method their distance is noted down. The first method is believed to be the most efficient method to know the cardiovascular fitness.

2. Skin Fold Measurement:

In this test , calipers skin is used to determine the thickness of fat on various parts of the body After measuring the thickness of different areas of the body, the measurements are then incorporated into the form of an equation (different equation for boys and girls) to calculate the body density. After calculating body density, it is then put in equation to calculate the percentage of fat in the body. All the measurements must be taken on the right side of the body.
The following three parts are measured:
(a) The skin fold around the abdominal region
(b) Chest skinfold
(c) Arm skinfold
