In addition to weight, everyone's body fat also has certain indicators. If you want to build a muscle, your body fat should not be too high. People with high body fat are too obese, and the probability of getting sick will increase. People with low body fat rate will have symptoms such as osteoporosis. Generally, women's body fat is slightly higher than that of men, which is about 25% to 28%. Let's take a look at the comparison table of female body fat percentage.
Too high or too low body fat rate is not good. If the body fat rate is too high, the weight over 20% of the normal value can be regarded as obesity. Obesity means lack of exercise, overnutrition or some diseases of endocrine system, which are often complicated with hypertension, hyperlipidemia, arteriosclerosis, coronary heart disease, diabetes, cholecystitis and other diseases;
If the body fat rate is too low, which is lower than the safe lower limit of body fat content, that is, 5% for men and 13%~ 15% for women, it may cause dysfunction. And too little fat can lead to osteoporosis. Due to insufficient body fat and estrogen level, the combination of calcium and bone is affected, and normal bone density cannot be maintained. Therefore, osteoporosis and fractures are prone to occur.
Especially, the body fat rate of developing girls is low, which is more harmful. Too much dieting and too little body fat will reduce the secretion of estrogen in the body, make menstruation disorder and even affect the development of reproductive organs.
Comparison table of female body fat rate-calculation of body fat rate: calculation of body mass index
If you want to know your body fat rate, you can use the following two formulas.
① Body mass index = weight (kg) ÷ (height × height) (m)
② Body fat rate: 1.2× body mass index +0.23× age -5.4- 10.8× sex (male 1, female 0).
8%~ 10% The competitive state achieved by a very small number of female athletes (which will cause amenorrhea, menstrual disorder and chest contraction)
1 1%~ 13% dorsal muscle is exposed, and the division of the external abdominal oblique muscle is more obvious (competitive state of female bodybuilders)
14%~ 16% dorsal muscles are exposed and abdominal muscles are more divided.
(17%~25% is the ideal body fat rate for women)
From 17% to 19%, the fat in all parts of the body is not slack, and the abdominal muscles are obviously divided.
20%~22% of all parts of the body do not relax, abdominal muscles begin to appear, and the block is not obvious.
23%~25% of body fat is basically not slack, and abdominal muscles are not exposed.
26%~28% of body fat is obviously relaxed in the waist and abdomen, and the abdominal muscles are not exposed.
29%~3 1% abdominal muscles are not exposed, and the waist circumference is usually 8 1~85 cm.
32%~34% of the abdominal muscles are not exposed, and the waist circumference is usually 86~90 cm.
35%~37% of the abdominal muscles are not exposed, and the waist circumference is usually 9 1~95 cm.
38%~40% of the abdominal muscles are not exposed, and the waist circumference is usually 96~ 100 cm.
The abdominal muscles above 4 1% are not exposed, and the waist circumference is usually above 10 1 cm.
