Obesity is the result of metabolism and energy balance. You are in a positive energy balance if the amount of energy from food exceeds energy for vital functions of the base of physical activity during leisure and work at DIN. That means you eat what you eat with physical activity.
Although obesity itself is not always pose a health risk, obesity is often associated with different diseases that affect metabolism, cardiovascular disease and musculo-skeletal. Hypertension, hypercholesterolemia and hyperglycemia, coronary heart disease and osteoarthritis of the knee and hip affect performance, work capacity and quality of life.
Who’s overweight?
Overweight refers to the presence of excess fat in the body. The best way to determine whether a person is overweight is by using the body mass index, BMI. This value is calculated by dividing weight (in kilograms) of the person who won by the square of the person (in meters).
BMI = weight (kg) / (height x height (m))
For example, a 60 kg with a height of 160 cm, BMI:
60 (kg) / (1.6 x 1.6 (m)) = 23.4
The body mass index does not describe the amount of fat, but rather serves as a means of comparison between individuals in relation to overweight or underweight. The value of the BMI does not distinguish between muscle and adipose tissue. For example, one lifter can have a BMI indicating obesity, although the only person, big muscles and little fat. To make this distinction, should be the thickness of skin folds were measured on the trunk and limbs. BMI is a reliable way to assess the relative weight of a person other than the strength training athletes.
This classification is true for data control and the emphasis on weight-related illnesses for several years in relation to population trends.
The classification applies to men and women. Calculated in this way, a man of 170 cm in height is normal 54-72 kg, 73-87 kg in weight moderately and significantly overweight, if more than 87 kg, while the figure of a woman of 160 cm height would be 48 -64 kg, 65-77 kg and over 77 kg. This means that you’re not the figure of a supermodel to have to stay within the normal weight does not pose a risk to health. Polar A5 Heart Rate Monitor includes BMI calculation and design.
