Where is leg length usually measured? What are the normal body proportions?

Most of them are measured from the hip bones, and the normal body proportions are seven heads, which is more in line with the Asian body proportions.

The length of the legs should be the distance from the heel to the base of the thigh, and the normal body proportion is that the leg should be slightly longer than the waist. In addition, there should be a control for weight and height.

Most are measured from the hip bone. The normal body proportions are seven heads and bodies, which are more in line with the body proportions.

Measurement of leg length of the lower extremity, including thigh length, calf length, and total leg length and total leg length of the lower extremity. Since it is not possible to find a very exact anatomical location outside the body surface, there may be some variation between different measurers.

The ratio of leg length to height** is:1. If it is greater than this number, it can be counted as leg length, and less than this number can be counted as leg short.

The ratio of leg length and height equal to ** division is the most perfect. For girls who love beauty, try to choose scientific methods to make their legs look better and exercise regularly.

Benefits of leg length

The legs are long and tall, and the body is well proportioned; It's easier to get to things in high places; Good photo effect and so on.

Disadvantages of long legs

The legs are too long to choose trousers, the pants are long enough, the waist is too loose, the waist is suitable and the pants are not long enough; The balance and coordination of the limbs are not so good; It is easy to sit lame when there is not enough space.

Measurements are performed using a fold algorithm from the anterior superior iliac spinous point (or pubic symphysis point) to the ground, medial malleolus point, and tibial point (as is the case for all measurements involving the thigh segment), because the exact location of the beginning of the thigh (apex of the femoral head) cannot be found on the surface.

Academically, the height minus the sitting height is used to indicate the leg length, and the Mahalobis torso leg length index is used to reflect the upper and lower body proportions.

Malcolm trunk leg length index = [(height - sitting height) sitting height] 100, which is the most reliable and valuable quantitative index of the leg-to-body ratio, which lays the foundation for the study of the leg-to-body ratio.

Leg length is expressed by perineal height or height minus sitting height: with the same height, women's legs are longer than men's; However, since the leg-to-body ratio is positively correlated with height, the larger the height, the larger the leg-to-body ratio; The leg-to-body ratio of males was slightly larger than that of females, and the difference was significant (P<; The extreme value of the leg-to-body ratio is also slightly larger for males than females. Therefore, long legs are not a feminine trait.

To measure the length of your legs, you need to stand up straight with your legs and measure the meter ruler along your legs to your crotch**It's the crotch, you touch your waist with your hands, and the hard bone is the crotch. When measuring, the meter ruler should not be loose, and the measured number will not be accurate if it is loose, so it must be close to the leg. It is absolutely wrong to measure the length of a leg from the navel.

Hip position Measure from below the buttocks. (Model Measurement Method) ps, the amount of bone which protrudes most from the hip line to the cervical vertebrae is the upper body.

Personally, I believe that the length of the human leg is measured by the distance from the anterior superior iliac spine to the medial malleolus of the foot, which is the length of the leg of the human lower limb.

Take the navel as the boundary to measure the length below the navel, and the ratio of height is the ** division ratio.

You can also measure it yourself, take a cotton rope, tie a small piece of weight at one end, and pinch it with your hands at the other end.

Hang the rope down, tie the weight to the ground at one end, do not hang on the body, and draw the other end at the level of the navel.

Tie a knot to make a mark, and then take it down and measure the length of that section with a small ruler.

Leg length is generally calculated from the waist circumference.

The folded line between the buttocks and the thighs,

Start from the pelvic bone and work your way up to the soles of the feet.

Crotch bone You touch your pelvis in** from the ** measure.

If you keep touching your belly, you'll feel the protruding bones, and it's supposed to be there.

Measure from the ankle to the base of the thigh.

Due to the beginning of the thigh (the tip of the femoral head), the exact location cannot be found on the outside. Therefore, the total length of the lower limb (lower limb length), the total leg length (leg length), and the length of the thigh are generally measured by a folding algorithm from the anterior superior iliac spinous point (or pubic symphysis point) to the ground, medial malleolus point, and tibial point (all measurement indicators involving the thigh segment are lineage). There are also approximate measurements using the large rotor point as a reference measurement point.

In practice, some more measurable data are usually used to represent leg length, that is, leg length in a generalized sense, from large to small, in order of iliac crest height, posterior superior iliac spine height, anterior superior iliac spine point height, greater trochanter point height, pubic symphysis height, perineal height, height minus sitting height, gluteal groove height. It is also used to subtract the height of the medial malleolus or the height of the lateral malleolus to indicate the length of the leg by subtracting the height of the medial malleolus from the height of the umbilicus, and the height of the anterior superior iliac spine point minus the height of the medial malleolus.

The most standard body proportions are: 1, that is, the length below the navel is higher than the whole body.

Anatomically and anthropometrically strictly defined leg length, the scientific name is full leg length, which is the narrow sense of leg length and the real leg length; It is equal to the length of the thigh plus the length of the calf, or the full length of the lower limb minus the height of the inner ankle. However, because the femoral head is deeply embedded in the acetabulum, the top of the thigh cannot be palpated, so the upper end of the thigh cannot be accurately determined.

Perineal height) 100: Asian male average, Asian female average ; The average for European and American men is that European and American women are all dressed as equals.

Expand the information of the banquet:

Meaning. Divide a line segment into two parts, the ratio of the length of the shorter part to the longer part is equal to the ratio of the length of the longer part to the overall length, and the ratio is an irrational number, and the approximate value of the first three digits is. Because the shape designed according to this ratio is very beautiful, it is called ** ratio, also known as the ratio of the outside to the outside.

This is a very interesting number, which we have approximated, and can be found by simple calculations:

The role of this value not only exists in art fields such as painting, sculpture, architecture, etc., but also has a non-negligible role in management, engineering design, etc.

The total leg length (leg length) is generally measured by a folding algorithm from the anterior superior iliac spine (or pubic symphysis) to the ground, medial malleolus, and tibia (as is the case for all thigh-related measurements). There are also approximate measurements using the large rotor point as a reference measurement point. The total leg length (leg length) is determined differently using different measuring points (greater trochanteric site, pubic symphysis site, or anterior superior iliac spine site).

Neither measurement can measure the precise anatomical length of the whole leg (leg length).

1. The large rotor point is high.

The height of the large trochanter point + 23mm is the length of the lower limb, which is compared with the height.

Strictly speaking, the lower limb length should start from the apex of the femoral head, but in vivo measurements, it is difficult to find this point. It is also problematic to calculate lower limb length by using the greater trochanter as the starting point plus the average of the distance between the greater trochanter and the apex of the femoral head. Although the shape of the trochanter protrudes from the surface of the human body, it is a spherical surface, and it is difficult to determine the measurement point.

2. The anterior superior iliac spines are high.

The height of the anterior superior iliac spine point is -40 mm as the length of the lower limb, which is compared with the height. In anthropometric measurements, lower extremity length is often calculated by subtracting the average of the anterior superior iliac spine to the apex of the femoral head from the anterior superior iliac spine.

3. High gluteal groove.

The length of the lower limb was taken from the lowest edge of the gluteal cleft, and the distance from the spinous process of the seventh cervical vertebra to the lowest edge of the gluteal groove was taken as the length of the trunk.

4. High perineum.

The perineal height is the length of the lower limbs, compared with the height. In different references, the perineal point can be the intersection of the line of the inferior point of the ischial tuberosity on the left and right sides and the median sagittal plane, or it can be located at the inferior border of the pubic symphysis. The perineal height measured by the former is actually the height minus the sitting height.

Secondly, when measuring perineal height, the subject adopts a standing posture, and the perineal point is often difficult to determine, and the position and tightness of the movable ruler card have an impact on the measurement results. In some literature, perineal height data are informative.

5. Sitting height and Mahalanobis index.

The sitting height is the trunk length, the height is reduced by the sitting height is the lower limb length, and the Marhalcomb torso leg length index reflects the proportions of the upper and lower parts of the body.
