The number "Five-Five" means that the ratio of upper and lower body is 1 to 1. In fact, it is only a rough and exaggerated description of the leg-to-body ratio. The accurate leg-to-body ratio still depends on Mahalanobis's trunk leg length index.

People often say that a figure of 50-50 generally means (umbilical height/height) × 100=50. But in fact, the average Mahalanobis index is 85. 10 (middle leg type), and the average value of (umbilical height/height) × 100 is 58.55. The average Mahalanobis index is 83.4 1 (short leg), and the average value of (umbilical height/height) × 100 is 58. 13.

Mahalanobis trunk leg length index, which is equal to [(height-sitting height)/sitting height ]× 100, is the most reliable and valuable quantitative index to explore the leg-to-body ratio, laying a foundation for the study of leg-to-body ratio.

Extended data:

According to the following calculation method:

A, the calculation method of standard weight

Male =50+ (height H- 150)×0.75+ (age -2 1)÷5.

Female =50+(H- 150)×0.32+ (age -2 1) ÷5.

Second, the calculation method of female standard figure

1, bust ≈ hip =H×0.535 hip =H×0.565.
