Calculation of body mass
BMI can be calculated by dividing the weight in kilograms by length in square meters. BMI does not measure body fat, so body mass index (BMI) is not accurate in athletes. Muscle is not an increase in weight, In the body as well.
BMI classification
Body Mass Index (BMI) is based on several categories:
- People with a BMI of less than 18.5 are classified as thinner or underweight.
- People with a BMI of 18.5-24.9 are classified as naturally overweight.
- People with a BMI of 25.0-29.9 are classified as overweight.
- People with a mass index of 30 or above are classified as obese.
The difference between weight and mass
- A fixed body mass does not change from one place to another, be it on Earth, in outer space, or on the moon, but the weight changes outside the earth, due to a decrease in gravity in other planets.
- Using a weight mass index for athletes is not always an ideal tool, because athletes can weigh more than non-athletes. Muscle is more dense than fat, which contributes to weight gain, and gender diversity plays an important role. To store more fat in their bodies than men, and older people tend to have less muscle mass than younger adults, and tend to store more fat in the body.
