The lower body covering portion 21 is a lower body covering means that substantially covers a portion of the lower body other than the toes. The lower body covering portion 21 applies an appropriate pressure to the lower body of the wearer 4, thereby supporting the deep muscles of the lower body and promoting the blood flow of the wearer 4. Here, the lower body covering portion 21 is formed at a position other than the above-described opening portion 22, winding portion 23, external rotation support portion 24, pump support portion 25, hooking portion 26, and lower body connecting portion 27 in the lower garment 20. Then, the lower garment 20 is formed by sewing together with the winding part 23 and the pump support part 25. Moreover, the shape of this lower body coating | coated part 21 can apply an appropriate shape according to the height, physique, etc. of the wearer 4, and is not restricted to the thing of illustration. Further, the lower body covering portion 21 is formed of an elastic material (for example, nylon, polyurethane, etc.) that can ensure appropriate comfort and is in close contact with the lower body of the wearer 4.

(Configuration-Underwear-Opening)
The opening 22 is an opening means for constantly maintaining the crotch portion of the wearer 4 in an open state, and is a hole formed so as to penetrate from the outer surface of the lower garment 20 to the lining. Here, the “open state” indicates a state where the crotch portion is exposed to the outside. The specific range of the “groin area” is an arbitrary area including at least the outer end of the urination organ of the wearer 4. However, in the first embodiment, as shown in FIG. 1B, the opening 22 extends from about 10 cm below the navel to about 3 cm below the thigh root, and in the width direction the lower garment. It is assumed that it extends over almost the entire width of 20. The opening 22 extends not only to the front surface of the lower garment 20 but also to a portion (crotch) between the front surface and the rear surface. However, the specific region of the opening 22 is not limited to that shown in the first embodiment. For example, since the position of the crotch part varies depending on the gender of the wearer 4, the specific position of the opening 22 may be appropriately changed. Further, the vertical direction may be wide open so as to reach the inner thigh or the knee area. In the width direction, a large opening may be provided from the front surface of the lower garment 20 to the rear surface through the side surface.

  As an advantage of providing the opening 22 in this manner, first, the wearer 4 can easily urinate. That is, when the wearer 4 wears the undergarment 20 after wearing the underwear 5 as in the present application, the crotch portion of the underwear 5 of the wearer 4 is always kept open by the opening 22. The wearer 4 can easily urinate by taking off only the underwear 5 or by using a hole for urination provided on the front surface of the underwear 5.

  Second, the wearer 4 can comfortably perform the crotch opening operation. That is, since the opening 22 extends between the inner root of the right leg thigh and the inner root of the left leg thigh, the hip joint of the wearer 4 is not compressed by the lower garment 20, It is possible to prevent the crotch opening operation of the wearer 4 from being hindered by the stretching force of the lower body covering portion 21.

(Configuration-Underwear-Winding part)
The winding portion 23 is a winding means for winding the upper end of the lower garment 20 around the waist of the wearer 4 or releasing the winding, and enables the wearer 4 to quickly and easily defecate. It is a means to do.

Is wound around the waist of the wearer 4, and in this state, the hook surface of the right protrusion 23a and the loop surface of the left protrusion 23b are overlapped with each other. As a result, the hooking surface and the loop surface are bonded to complete the winding while the right protruding portion 23a and the left protruding portion 23b are brought into close contact with the waist of the wearer 4 by the force of the elastic member 23c to return to the original state.

  Further, in the state where the winding portion 23 is wound around the wearer 4 in this way, the hook surface of the right protruding portion 23a and the loop surface of the left protruding portion 23b are separated from each other, thereby opening the opening portion in a front view. The area 22 and the area above the winding part 23 are communicated with each other. Therefore, as shown in FIG.3 (b), the upper end part of the lower garment 20 droops back by the dead weight of the upper end of the lower garment 20, and the wearer's 4 buttocks will be in an open state. Therefore, the wearer 4 can easily defecate. That is, in the conventional wear, it was necessary to slide down the lower garment 20 at the time of defecation, but the wear that supports this kind of muscle is formed so as to be in close contact with the body of the wearer 4 and thus it is difficult to slide down. there were. However, the fatigue reducing wear 1 according to the first embodiment does not require the lower garment 20 to be dragged down, and the wearer 4 can use the extremely easy method of peeling the right and left protruding portions 23a and 23b from each other. Since the buttocks can be opened, the wearer 4 can easily defecate.

Here, the distribution of the load applied from the right foot of the wearer 4 is displayed on the right side, and the distribution of the load applied from the left foot of the wearer 4 is displayed on the left side. Moreover, the position of the gravity center of the wearer 4 specified based on the magnitude | size of the load applied from the wearer's 4 leg | foot is plotted at the approximate center position.

  As shown in FIG. 4, at the time of wearing, the posture is improved by the spine standing muscle assisting portion 13, thereby increasing the installation area of the right foot (particularly noticeable for the portion surrounded by a circle) You can see that the center of gravity is close to the center of the body. Therefore, it is possible to maintain a well-balanced posture for the wearer 4, to increase the movable range of the arm during the arm raising operation, and to prevent back pain and stiff shoulders.

(Experiment B)
Then, it shows below about the experiment (experiment B) which measures the discharge rate of a muscle. FIGS. 5A and 5B are diagrams showing instantaneous myoelectric values in Experiment B, in which FIG. 5A is an instantaneous myoelectric value when the fatigue reducing wear 1 is not worn, and FIG. 5B is a wearing of the fatigue reducing wear 1. Indicates the instantaneous myoelectric value. FIG. 6 is a graph showing myoelectric integration values (described later) in Experiment B. In this experiment B, specifically, when the fatigue reduction wearer 1 is not worn and worn, the subject has four types of actions (an action to take the box, an action to lift the box, and a state in which the box is lifted). The action of maintaining for 5 seconds and the action of lowering the box) are performed, and the discharge rate for each muscle of the subject in each action (discharge rate when the maximum muscle strength is 100. Hereinafter, referred to as “myoelectric moment value”) Measured, and the integrated value of the discharge rate (hereinafter referred to as “myoelectric integrated value”) was calculated for each muscle. Here, the horizontal axis of FIG. 5 represents time (msec), and the vertical axis represents the myoelectric instantaneous value (%). In addition, the horizontal axis in FIG. 6 indicates the name of each muscle to be measured, and the vertical axis indicates the myoelectric integration value (%). A box with a weight of 16 kg was used. Further, as shown in FIG. 6, the muscles to be measured were four muscles of the deltoid muscle (front part), the spine standing muscle, the gastrocnemius, and the biceps femoris. In FIG. 5, only the myoelectric instantaneous value of the deltoid muscle is shown.

  First, from the results shown in FIG. 5, by wearing the fatigue reduction wear 1 according to the first embodiment, the myoelectric instantaneous value of the deltoid muscle is particularly prominent in the operation of lifting the box and the operation of maintaining for 5 seconds. It can be confirmed that it is decreasing. Moreover, it can be seen from the results shown in FIG. 6 that the electromyographic integrated values of the deltoid muscles and the spine standing muscles can be greatly reduced by wearing the fatigue reduction wear 1 shown in the first embodiment. In particular, it can be seen that the deltoid muscles can be reduced by about 50% compared to when not worn.

Further, the left column shows a fatigue measurement method using VAS (visual analog scale), and the right column shows a measurement method using flicker values.

  Here, the method of measuring fatigue level by VAS is to write a mark on a line with contrasting items on both ends according to the degree of how the subject feels, and based on the length from the end to the mark of the subject This is a method for converting the subjectivity into a numerical value, and indicates that the greater the numerical value (hereinafter referred to as the VAS numerical value), the greater the degree of fatigue. In addition, the method of measuring the degree of fatigue by flicker value is a method of measuring the numerical value of the number of revolutions per second at the boundary where flicker is seen or not seen by flickering light by rotation of the light shielding plate and increasing the rotation speed. The smaller the numerical value (hereinafter referred to as flicker value), the greater the fatigue level. In addition, since the concrete procedure etc. of these fatigue degree measuring methods are well-known, description is abbreviate | omitted.

  Moreover, the period during which the measurement was carried out was a total of three weeks from March 3 to March 24 for both the subject wearing the fatigue reduction wearer 1 and the subject not wearing it, and the subject worked on weekdays. The measurement was performed later. In addition, in the example related to the subject wearing the fatigue reduction wear 1 (below), strictly speaking, the fatigue reduction wear 1 is not worn every day on weekdays, and the fatigue reduction wear 1 is worn only for about 2 to 3 days a week. . The ascending test subject and the descending test subject are both craftsmen, and the content of the work is a work performed by a general sculptor in a day.

  First, regarding subjects who do not wear the fatigue reduction wear 1, it can be confirmed that on weekdays, the VAS value continues to increase and the flicker value continues to decrease compared to the previous day on weekdays. Here, regarding the subject wearing the fatigue reduction wear 1, as shown in the lower row, on the day when the fatigue reduction wear 1 is not worn on weekdays, the numerical value of VAS shows a high value and the flicker value shows a low value. Show. However, for many days of wearing the fatigue reduction wearer 1 on weekdays, the VAS figure is clearly lower than the previous day (especially March 7 and March in circles). 13 and March 22), it can be seen that the flicker value is clearly increasing (particularly March 5, March 7 and March 22 surrounded by a circle). Therefore, it turns out that the fatigue degree of the wearer 4 after finishing work can be drastically reduced by wearing the fatigue reduction wear 1 which concerns on this Embodiment 1, and performing work.
