Body Mass Index

The Body Mass Index - BMI

A body mass index can also be known as the Quetelet index. It is a measure of statistical significance which compares an individual in both height and weight. It's a great tool to assess the healthy body weight . The measurement based on how tall an individual is. It's accurate and is the most popular 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) criteria for obesity and overweight through BMI you will be able to discover whether the individual falls within the categories of overweight, underweight overweight or falls in the category of obese.

Calculation Of BMI

BMI BMI of an person is determined with the help of the following formula:Body Mass Index (BMI) = Body weight / (height x height)
Here the weight of the individual will be noted in kilograms while the height is calculated in metres.
Example:
Suppose an individual's body weight is 70kg, and his height is 1.60 m. Calculate these numbers.
BMI = 70 / (1.60 x 1.60) = 70 / 2.56 = 27.34 kg/m2
Today, with the help of guidelines from the World Health Organisation (WHO) the criteria for obese and overweight have been updated.
By BMI by BMI to learn if the person falls into the category of normal or overweight.
obesity, weight, or falls under the category of overweight.

Precautions During Measurements

These precautions should be observed while taking measurements to determine BMI.

  1. The body's weight has to be weighed using an accurate and reliable weighing machine.
  2. The student who's body weight is to be measured, must wear minimum required clothes specially without shoes.
  3. During the measurement of 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 that is used to examine and judge fitness levels of youth. The first version of the test was published in 1958, then updated in 1966 and after that in 1976. Many changes in the test's test battery were implemented in the year 1976 for the AAPHER youth fitness test. This test is designed to test the fitness levels of youth. The tests assess the body's composition, flexibility, agility, coordination as well as upper body strength and endurance for aerobics. The tests are designed in a way they can be administered by experts working on the job.

Below are the test component that comprise AAPHERD physical fitness test: 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. 1.5 mile and 12 minute run for children age 13 and over.

In the year 1980, AAPHERD introduced the 'Physical Best' test which included the following items:
1. 1 1/2 mile walk or a 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 awards students for their level of physical fitness in the above actions.

Shuttle Run

This competition measures speed, quickness and agility of the participants. Create two parallel lines that are 30 feet apart, and then place two blocks of wood, to one side. Students begin on the parallel line. On the signal 'Go' the student races through the blocks, picks one of them, runs back to the starting line, places block in the middle of the line, goes back, and picks up the second block and runs across the starting line. Blocks should be placed between the lines.

Pull-Ups Testing

A student hangs from a horizontal bar that the student is able to be hung from, arms fully extended, and feet free from the floor. They can use either an overhand grip or an underhand grip. Students of short heights can be lifted to a starting position. They will raise the body until the your chin is clear of the bar, then lower
body to full hang starting position. The student does as many correct pull-ups as he is able to.

Flexed- Arm Hang Testing

By using an overhand or underhand grip, student is able to assume a flexed arm hang in a position where the chin is clear of the bar. Students can be lifted up to this position. The student holds the position indefinitely.

Flexed Arm Hang Scoring

The chest of the student must be held close to the bar, with the legs hanging straight. The timer is stopped at the point that the student's head touches or falls under the bar.

Standing Long Jump

Standing long leaps are a frequent and easy test that tests powerful leg strength. The participant stands in front of one of the lines marked on the ground. With their feet slightly separated. A two-foot jump and landing can be achieved using the swing of the arms and bending of knees to create forward thrust. The participant tries to leap as far as possible and landing on both feet without falling backwards. Three attempts are permitted. The measurement is taken from beginning point to point of contact at landing the distance that is the longest jumped in the three best attempts is recorded.

50-Yard Dash

It is a test to evaluate the speed of the student. The student stands at the line of start and begins running on the signal 'Go'. As soon as the distance has been completed, the duration taken to complete 50 yards is recorded.

The new test for AAPHERD is designed to assess 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 watches. If this method is not sufficient, the students are told to do a 12-minute run. In this method their distance is recorded. This is the first method that is considered as the best method to determine the fitness of the heart.

2. Skin Fold Measurement:

In this test , calipers skin is used to measure the fat thickness on various body parts. After measuring the thickness of different parts of the body, these measurements are then incorporated into an equation (different equation for males and females) which is used to calculate the body's density. After calculating body density, it's put into an equation to calculate the percentage of fat in the body. All measurements should be done by examining the back of the body.
The three parts that follow are measured:
(a) Skinfolds of the abdomen
(b) Chest skinfold
(c) Arm skinfold

What is ransomware exactly?

Technology is constantly evolving the intruders employ ever more sophisticated methods of stealing our money. We get messages in our mail and mobile devices with links to images or programs which "interest us" However, in actual it's viruses that can take control of the mobile device or our computer. For instance, you could make your advertisement on an advertising platform to sell a product. Within a few hours you get an SMS with an offer to trade the product you are selling for another and a link to the images of this item. In fact, if you open this link on Android device, it will download an additional program that will transfer all your money to the accounts belonging to the intruder. Another common attack technique is to mail out messages with links text and links, which encourage users to click on the link. For example, an attacker could offer you good job and you must fill out some form by clicking the link. Your mobile or computer will then be infected...

Calculator SearchPrevious, navigation, Jump (Calcium)Next (Caleb)A basic calculator A calculator  is a device for performing calculations . These days, most calculators incorporate general-purpose computing systems, however, they're often made to carry out specific tasks. For instance graphing calculators focus on graph-centered math like trigonometry as well as statistics. Furthermore, modern calculators tend to be larger and more portable than a majority of computers however some personal digital assistants (PDAs) are similar in terms of size to hand held calculators. Since calculators  are miniaturized, someday devices that are the size of credit cards will be able to do the same calculations like today's huge scientific calculators. Another potential advancement could be comparable to a portable computer which has notations that do not require buttons, but written directly on an LCD. By this method, the requirement for buttons could be removed and the siz...

Parts per Million by Weight in Water It's the concentration of gas at ppm that is found in water. It is usually expressed in terms of weight. To determine the concentration with metric units how dense is water is necessary. In pure waters, the density is 1000.0000 kilograms for every millimeter 3. at temperatures of 3.98degC and the standard atmospheric  pressure that was in use up to 1969. This was the first classification of the kilogram. The current definition of the Kilo is that it is equivalent in weight to that of the prototype that is used in international standards for the kilogram. High-purity water (VSMOW) in temperatures up to 4°C (IPTS-68) in regular atmospheric  pressure has been measured at the density averaged at 999.9750 kg/m 3. . [5] The density of water is influenced by pressure, temperature and impurities i.e. the dissolved gasses and salinity of the water. A shocking concentration  of the gases present in the water can affect the density ...
