BMI – Importance of Body Mass Index for Fitness
The Body Mass Index is also known as Quetelet Index because it was invented by Adolphe Quetelet. In fact, it is the statistical measurement which compares an individual’s weight and height. Although it does not actually measure the percentage of body fat yet it is a very useful tool to estimate a healthy body weight based on how tall an individual is. Indeed, it is the most widely used tool to identify the weight problem. BMI is very easy to measure and evaluate. With the help of BMI one can come to know whether one is underweight, overweight, obese or normal. BMI is defined as an individual’s body weight divided by the square of his height. BMI can be determined using a BMI chart. Its value is measured in kg/m2. BMI can be balanced by regular exercise through fitness equipment like abdominal crunch machine, rowing machine, leg press machine, treadmills etc.
The body mass index (BMI), or Quetelet index, is a heuristic proxy for human body fat based on an individual’s weight and height. (Wikipedia)
This fitness testing is used to measure body composition. In this testing/index the health and fitness abilities of an individual is based upon the relationship of height and weight. Here height is considered in meters and centimetres; weight is considered in kilograms and grams. BMI is calculated by taking an individual’s weight (in Kg and gm) and dividing it by his height (m and cm) square. BMI can be improved with regular exercise with gym equipment.
i.e. Weight ÷(height x height)
This is just a guide to know the overweight content in the body. This test can be a preventive step towards obesity. Some of the good home gym equipment for healthy BMI and known as BMI fitness equipment are dumbbells, barbells, exercise bench, chin-up bar, jump rope, etc
Use the table to determine your BMI rating.
CATEGORY MEN WOMEN
Underweight Less than 20 Less than 19
Healthy 20 to 25 19 to 24
Overweight 26 to 30 25 to 30
Obese More than 30 More than 30
PRECAUTIONS TO BE TAKEN DURING MEASUREMENT:
- The body weight must be taken on a reliable and perfect weighing machine.
- One must wear minimum required clothes while taking the weight.
- While measuring the height one should be bare- footed and the body should be absolutely straight.
WHR is the ratio of circumference of waist to that of the hips. It is calculated by measuring the smaller circumference of the waist (above the belly) and dividing by the circumference of the hip at the widest part of the hip. This is applicable to both men and women. WHR is a good indicator of health and attractiveness of a person. The ratio 0.7 is considered good health among women, whereas the ratio at around 0.9 is considered health among men. These persons have less chance of health problems. These people will also look attractive. The measurements can be taken inches or centimetres. It’s a measurement you can easily do yourself with a tape measure and a calculator. It predicts the risk to your health from a measurement of the amount of abdominal / belly fat you carry.The truth is that obesity and the risks it may pose to you have little to do with what the scales say. How much fat you have on your body and specifically how much you have in the abdominal area of your body is what counts?
