What Are Body Proportions?
Body proportions
- BMI index = weight (kg) / [height (m)] ²: Asian men average 21.55, Asian women average 20.77 [2]
- The "false width" theory defines the width as the true width and the large trochanter width or hip width as the false width.
Body proportion measurement
- According to the "false palate width" theory, the width of the intercondylar space of a normal person is larger than the width of the greater trochanter, and the width of the greater trochanter is greater than the width of the intertrochanter [49] . actually not:
- (1) It is often said that males have narrow pelvis and females have wide pelvis. This is actually relative to height. Women with the same height have wider pelvis. In terms of average pelvic width, men and women are similar, and women are not larger than men in every region [50] .
- (2) Secondly, the pelvic width is also called the intercondylar width, which is the width of the abdomen, not the width of the buttocks [14] ; the width between the points of the greater trochanter is close to the width of the buttocks; Width <hip width.
- (3) In the average size of the human body, only the measured values of the width between the large trochanter points and the hip width are always slightly larger for women than for men. With the same height, the difference between the sexes is extremely significant. In other words, women's hip joints are wider, and the width from the abdomen to the hips increases more significantly, constituting the curvy beauty peculiar to women. The relevant data is as follows [2] :
- Pelvic width, intertrochanteric width and hip width (3 photos)
project | male | Female | Gender difference |
Height (mm) | 1714 | 1591.3 | 122.7 |
Pelvic width (mm) | 272.2 | 263 | 9.2 |
(Pelvic width / height) × 100 | 15.88 | 16.53 | -0.65 |
Large rotor width (mm) | 306.7 | 318.2 | -11.5 |
(Big rotor width / height) × 100 | 17.89 | 20.00 | -2.10 |
(Pelvic width / large trochanter width) × 100 | 88.75 | 82.65 | 6.10 |
Hip width (mm) | 327.80 | 330.70 | -2.90 |
(Hip width / height) × 100 | 19.12 | 20.78 | -1.66 |
Reasons for body proportions
- At the widest part of the lower part of the human body, the female is below the greater trochanter, corresponding to the buttocks of the buttocks [52] .
- Women usually have a large amount of fat accumulation under the greater trochanter of the femur and the upper part of the outer side of the thigh, connecting forward with the fat in front of the thigh and backward with the fat in the buttocks [9] .
- Estrogen promotes the accumulation of fat in the hips and thighs and inhibits the accumulation of fat in the abdomen [5] . The fat stored in the hips and thighs contains Omega-3 polyunsaturated fatty acids (DHA), which is essential for fetal brain development [43] .
- Various methods may be able to reduce the fat under the rotor [53] , that is, the width of the hips is reduced, and it is closer to the width of the large rotor. However, the width of the large rotor is greater than the width of the rotor.
Body proportion conclusion
- In summary, the width of the greater trochanter is greater than the width of the pelvis, regardless of gender, and the accumulation of fat under the trochanter in women is a normal physiological phenomenon. Academically, there is no such word. Therefore, "false width" is a false concept .
