An experiment on differential threshold for pressure on the front and back parts of a lower leg was conducted using eighteen women as subjects. Another experiment for examining compressive feeling of trial stockings, which are controlled their clothing pressure distribution by changing loop length in course direction, was conducted.
The results obtained are as follows:
1) Differential threshold for pressure on the front part of a lower leg was constant ranging from 0 to about 25 gf/cm².
2) Differential threshold for pressure on the back part of a lower leg changed with the level of pressure. When the pressure is low, it was not as sensitive as that on the front part. When the pressure is more than 20 gf/cm², it was as sensitive as that on the front part.
3) Comfortable value of pressure on the front part of a lower lei was lower than that on the back hart.
4) Compressive feeling was more influenced by pressure on the front part of a lower leg than that on the back part.

The waist girth and the clothing pressure developed by a waistband (an inside belt in 2.5 cm width and 97.5 % length of the perfect fit) were measured and analyzed in relation to the time of day and the menstrual cycle under a controlled diet. Subjects were six women ranging from 22 to 40 in age. Both the waist girth and the waistband-pressure changed significantly according to the phase of menstrual cycle (those measured at from the latter half of the phase of higher basal body temperature (BBT) to the phase of menstruation were larger than those from the phase of lower BBT to the first half of the phase of higher BBT) . Therefore, the relation between waistband-pressures and waist girths were examined in the subjects who were in a certain phase of their menstrual cycle (i.e., within three days after the onset of higher BBT) . As a result, both the waist girth and the clothing pressure changed according to the time of day and increased significantly by taking the meals. The relation between X (the difference between the waist girths measured at 9: 30 a.m. and at any experimental times) and Y (the difference between the waistband-pressure at measured at 9: 30 a.m. and at any experimental times) was a straight line (Y=0.95X-0.09, α≤0.01) . From a hygienic point of view, we should consider the fact that the waist girth and the waistband-pressure undergo a considerable change according to the time of day, meals, and phases of menstrual cycle, before we decide to get clothes as our waists are compressed.
