The formula commonly used in the world to calculate human body weight, and the calculation of body proportion (more suitable for orientals) standard weight = (height cm- 100)x0.9(kg) standard weight (female) = (height cm- 100)x0.9(kg)-2.5(kg). Normal weight: standard weight+-(how many Jin) /{ 10%. Overweight: more than standard weight 10%, less than standard weight 20%. Body mass index = obesity: 20% above standard weight and 30% below standard weight. Moderate obesity: 30% above standard weight and 50% below standard weight. Severe obesity: 50% over standard weight. Height (m)} Normal woman = 19-24 Ideal constellation calculation method: (height -70)*0.6[ unit: kg] Beauty weight calculation method: The slim figure pursued by beauty-loving women is the so-called beauty weight, and its calculation method is to subtract 5 kg from their ideal healthy weight. This is a requirement for a better figure, and it is also the latest interpretation of the golden figure now. The perfect figure should be 665438+ 0.8% of the leg length below the waist, which is commonly known as the golden section. Chest circumference = height (cm) ×0.535, waist circumference = height (cm) ×0.365 and hip circumference = height (cm) ×0.565. The actual calculated index and the standard index of 3 cm are standard. Less than 5 cm means too slim (thin); More than 5 cm indicates that it is too plump (overweight). But the measurement standard of professional female model is different. Due to professional needs, their measurement standards have a certain gap with the normal standards. Generally, the ratio of female measurements is: bust is about equal to hip circumference, and waist circumference is about 23 cm smaller than bust or hip circumference. Through measurement and calculation, if any circumference is found to be different from the standard data, bodybuilding can make up for it Because targeted fitness can strengthen the coordinated development of "three measurements" and prevent imbalance. In addition, bodybuilding can also make the muscles and fat in all parts of the body evenly distributed, which is beneficial to bodybuilding. Another method: a scientific and convenient formula can help you know whether the size of the chest is just right for your figure. First measure the chest circumference (unit: cm), then measure the clear height, and then start the calculation. Bust/height =? The result is the size coefficient of your own chest. According to the result, see the corresponding judgment. Small chest: the coefficient is less than 0.49; The standard index is 0.5 to 0.53; The aesthetic standard is 0.54 to 0.6; Excessive chest circumference: the coefficient is greater than 0.6; The ideal weight-body ratio table for various heights is148cm155cm165cm 65438+. 8.2kg49.5kg 52.9K56.3kg59.9K62.8kg bust 80cm 82cm84cm86cm9 1cm waist 58cm59cm61cm63cm64cm85cm 85cm 91c.

The most commonly used formula for calculating the standard weight of human body is: standard weight (KG)=[ height (cm)- 100] × 0.9, or standard weight (KG)= height (cm)- 105. Weight over standard weight 10% is overweight, and over 20% is obese. Obesity is divided into one, two and three grades, and the third grade is severe obesity. Calculation method of body mass index: body mass index = weight (KG)÷ height 2(M2). Body mass index ≥24 indicates overweight and ≥30 indicates obesity.
