Description

  The present invention relates to a competition wear that enhances the athlete's athletic ability, and is particularly suitable as a swimwear.

  Form resistance is the largest resistance that athletes receive in water. Shape resistance is determined by the projected area of the swimmer viewed from the front in the direction of travel. Therefore, in order to reduce the shape resistance, it is effective for the athlete to keep a posture as parallel as possible to the water surface. In other words, when swimming, keep the entire body in parallel and straight to the surface of the water by keeping the hips, knees, and feet to sink downward relative to the position of the athlete's head. desirable.

  However, since gravity and buoyancy act in the vertical direction with respect to the center line of the body, the swimmer's posture tends to become unstable. On the other hand, the lower body has a higher bone density and more muscles than the upper body, so it is easier to sink in water than the upper body.

From this point of view, the following patent documents 1 and 2 are disclosed.
JP 2001-32104 A JP 2001-262409 A JP 2003-129310 A

  The swimwear disclosed in Japanese Patent Laid-Open No. 2001-32104 is a stretchable fabric that covers the body continuously over the torso and thighs, thereby preventing the submerged portion from the waist to the legs from sinking into the water. Yes.

  The swimmer needs the strength of the abdominal and back muscles in order to maintain the effective posture. However, when the muscles become tired during swimming, it becomes difficult to maintain the effective posture. The invention of Japanese Patent Laid-Open No. 2001-32104 does not consider the case where muscles are fatigued.

  Japanese Patent Application Laid-Open No. 2001-262409 discloses swimwear in which a material having high stretch strength is arranged over a wide range in order to tighten a swimmer's waist with a predetermined pressure.

  This prior art aims at stabilizing the posture during swimming by applying a pressure higher than a predetermined pressure around the waist of the swimmer. However, no consideration is given to positively maintaining the effective posture. Therefore, it would not be expected to be effective enough to prevent the waist and thighs from sinking.

  Japanese Patent Application Laid-Open No. 2003-129310 discloses swimwear that covers the waistline region of the region above the buttock including the waist with a belt-like stretchable fabric.

  This swimwear of the prior art aims at the effect that body shape can be corrected when a person with slack in the abdomen wears, and that it is easy to move in underwater exercise.

  A first object of the present invention is for swimming, in which a swimmer's posture is likely to be an effective posture that is parallel and straight to the water surface, and the effective posture is easily maintained even when the muscles of the swimmer are fatigued. To provide competition wear.

In recent years, inventions have been made on correction clothing that corrects the posture described below.
JP 2001-192903 A JP 2005-281899 A JP2004-107844

  Japanese Patent Application Laid-Open No. 2001-192903 discloses a girdle-like garment that is worn during daily life or sports, and that expands the range of motion of the waist and hip joints. This prior art girdle has a belt portion having a high tightening force that extends along the waistline through the center position of the back of the waist. Therefore, the belt center will be located above the pelvis.

Japanese Patent Application Laid-Open No. 2005-281899 discloses a girdle-like garment that improves the posture of the wearer and is comfortable and easy to move. In this prior art girdle, the pressure on the body is greater on the side than on the belly or waist.
Further, in this prior art girdle, a belt having a large tightening force is disposed around a position 2 to 3 cm above the upper anterior iliac spine. Thus, the center of the belt will be located above the upper end of the pelvis.

  Japanese Patent Application Laid-Open No. 2004-107844 discloses a girdle-like garment that aims to apply a force similar to the force that the muscles around the pelvis act on the pelvis. In this prior art garment, the belt portion having a large tightening force does not cover the front surface of the pelvis. Therefore, the force to tighten the pelvis from the surroundings will be weak.

  Therefore, the second object of the present invention is to enhance the athlete's exercise ability by covering a predetermined region of the pelvis with a belt portion having a large tightening force.

  A competition wear according to an aspect of the present invention is a competition wear made of stretchable fabric, formed of a stretchable first fabric and a second fabric, and along the waist direction of the second fabric. The elastic modulus is larger than the elastic modulus along the waist direction of the first fabric, the crotch in the wear and the lower periphery of the pelvis are covered with the first fabric, and the upper periphery of the pelvis in the wear is A belt-shaped first belt portion is formed to be covered with the second fabric, and the first belt portion includes a belt front portion that covers the upper portion of the pelvis from the front surface, and a belt back portion that covers the upper portion of the pelvis from the rear surface. A pair of belt side portions covering the upper part of the pelvis from the side surface, and the belt front portion, the belt back portion and the belt side portion respectively divide the first belt portion into four equal parts in the circumferential direction. Set to the area The upper end line of the first belt portion is inclined downward as it approaches the center of the belt front portion from the belt side portion, and the front upper end line of the belt front portion is the upper end of the pelvis or its Placed along a nearby level, essentially not covering the area above the pelvis, and essentially not covering the area above the back upper end line of the belt back, A virtual rear center line that is arranged at a position that is approximately 4 cm to 6 cm above the center of the front upper end and that divides the belt back part into two parts up and down is a virtual front part that divides the belt front part into two parts up and down. The first belt portion is formed so as to be a position approximately 4 cm to 6 cm above the average value from the center line.

  By stabilizing the pelvis from side to side and back and forth, the upper and lower body are stabilized and the form in the competition is also stabilized. Also, the pelvis is connected to the main muscles that run during running, such as the buttocks and thighs. In order for a muscle to exert a great strength, it is necessary that the muscle has an optimal length. When the pelvis is tilted backward, the muscles of the buttocks (gastrocnemius) and the muscles behind the thigh (hamstrings), which are important in running, contract, and cannot exert great muscle strength. When the pelvis is upright, the muscles are optimally lengthened and the muscular strength is easily exhibited.

According to the present invention, since the upper part of the pelvis is covered from the periphery by the second fabric having a high elastic modulus, the pelvis is difficult to swing from side to side and back and forth and is stabilized.
The belt back part is disposed at a position above the pelvis from the belt front part, and the offset couple is applied to the pelvis as a moment to erect the pelvis. As a result, the pelvis tends to be in an upright posture.

  In particular, even after the muscles that support the bones are fatigued, the inclination of the pelvis is easily stabilized, and the posture in which the pelvis is upright is easily maintained. Therefore, muscles such as the gluteus medius and hamstrings are likely to have an optimum length, and as a result, the muscular strength is easily exhibited.

  On the other hand, the second fabric having a large elastic modulus does not essentially cover the region above the pelvis. Therefore, there is no possibility that the second fabric having a large elastic modulus bites into the waist above the pelvis. Therefore, the change in the peripheral length due to respiration is not hindered, and there is no possibility that excessive pressure is applied to the abdomen.

  In the present invention, each of the first fabric and the second fabric may be a single material or a composite material. For example, the first fabric is constituted by the body fabric covering the entire area of the wear, and the belt portion is reinforced with a reinforced fabric such as a reinforced net, or the body fabric is impregnated or coated with the second fabric. It may be a dough.

In the present invention, the center of the rear upper end is arranged approximately 4 cm to 6 cm above the center of the front upper end, and the rear center line is arranged 4 cm to 6 cm above the front center line on average. The reason for limiting the facts by numerical values is as follows.
When the lower limit is less than 4 cm, the couple is not sufficiently exerted, and a sufficient effect cannot be obtained as compared with the case where the offset is not offset.
If the upper limit exceeds 6 cm, the belt's front lower end approaches the lower limbs, hindering the movement of the lower limbs, or the belt's front lower end to prevent the lower limbs from approaching the lower limbs. Must be small.

A rubber-like belt is disposed at the upper end portion of the first belt portion, and a storage portion formed by sewing a second fabric into a bag shape for storing the rubber-like belt is disposed. The upper end portion having these rubber-like belts and storage portions has an extremely large elastic modulus along the waistline direction. Therefore, the position of the line at the upper end of the first belt portion is an important element for exerting an appropriate couple.
That is, if the level difference between the center of the rear upper end and the center of the front upper end is less than 4 cm, the couple will not be sufficiently exhibited.
On the other hand, if the level difference between the center of the rear upper end and the center of the front upper end exceeds 6 cm, the upper end of the belt back part covers the upper side of the iliac bone, or the position of the rubber-like belt and the storage part at the front part of the belt As it goes down, the line at the lower end of the front part of the belt approaches the lower limbs. Such a belt front part causes discomfort and a decrease in exercise ability.

  In the present invention, the upper end line of the first belt portion is inclined downward from the center of the belt side portion (both ends of the front surface) toward the center of the belt front portion. Therefore, the front upper end line of the belt front portion can be arranged along the upper end of the sacrum or in the vicinity thereof.

  “The belt front portion, the belt back portion, and the pair of belt side portions are provided essentially continuously” means that the first fabric may be provided on a part of the first belt portion made of the second fabric. (There may be a portion with a small elastic modulus). Even when the first fabric having a small elastic modulus is slightly provided, it is possible to apply a large pressure to the pelvis from the periphery of the pelvis.

  “The line at the front upper end of the front part of the belt does not essentially cover the portion above the pelvis” means that the line at the front upper end is disposed above the upper end of the front surface of the sacrum. In addition, it means that the line at the front upper end is arranged below the upper end of the pelvis in the iliac bones on both sides of the front surface of the sacrum.

  “The front upper end line does not essentially cover the upper part of the rear upper end line” means that when a part of the back of the belt is formed of the first fabric, the first fabric portion is moved forward. This means that the front upper end line may be arranged so that the upper end line crosses.

  Except for swimwear, it is preferable that the elastic modulus E1 along the waist direction of the first fabric is set to 0.3 to 3.0 N / cm.

  If the elastic modulus E1 of the first fabric is smaller than 0.3 N / cm, the first fabric will be easily turned during exercise. On the other hand, if the elastic modulus E1 of the first fabric is greater than 3.0 N / cm, the movement of the lower limbs may be hindered by excessive tightening of the first fabric.

  From this viewpoint, the elastic modulus E1 of the first fabric is more preferably about 0.4 to 2.5 N / cm, and most preferably about 0.6 to 2.0 N / cm.

In addition to the swimwear, it may be preferable that the elastic modulus E2 along the waist direction of the second fabric is set to 3.0 to 14.0 N / cm.
If the elastic modulus E2 of the second fabric is smaller than 3.0 N / cm, the pressure on the waist by the second fabric may be too small to obtain a sufficient couple. On the other hand, if the elastic modulus E2 of the second fabric is greater than 14.0 N / cm, the tightening force on the waist may become too high, which may inhibit the movement of the waist or deteriorate blood circulation.

  From this point of view, the elastic modulus E2 of the second fabric is more preferably about 4.0 to 12.0 N / cm, further preferably about 4.5 to 11.0 N / cm, and 5.5 regardless of the type of competition. 10 N / cm may be most preferred.

  In addition to the swimwear, the division value (E2 / E1) obtained by dividing the elastic modulus E2 of the second fabric by the elastic modulus E1 of the first fabric is set to 2.0 to 25.0. Would be preferable.

If the division value (E2 / E1) is smaller than 2.0, the elastic modulus E2 of the second fabric will be too small, or the elastic modulus E1 of the first fabric will be too large. Therefore, the force applied to the outer periphery of the pelvis may be insufficient, or excessive pressure may be applied to the lower limbs.
On the other hand, if the division value (E2 / E1) is larger than 25.0, the elastic modulus E1 of the first fabric will be too small, or the elastic modulus E2 of the second fabric will be too large. Therefore, an excessive force may be applied to the pelvic outer periphery, or the first fabric may turn over and the movement may be hindered.

  From this viewpoint, the division value (E2 / E1) is more preferably about 3.0 to 20, and most preferably about 4.0 to 18.0.

  In addition to the swimwear, a subtraction value (E2-E1) obtained by subtracting the elastic modulus E1 of the first fabric from the elastic modulus E2 of the second fabric is set to 2.7 to 13.7 N / cm. Would be preferable.

If the subtracted value (E2-E1) is smaller than 2.7 N / cm, the elastic modulus E2 of the second fabric will be too small, or the elastic modulus E1 of the first fabric will be too large. Therefore, the force applied to the outer periphery of the pelvis may be insufficient, or excessive pressure may be applied to the abdomen.
On the other hand, if the subtracted value (E2-E1) is larger than 13.7 N / cm, the elastic modulus E1 of the first fabric will be too small, or the elastic modulus E2 of the second fabric will be too large. Therefore, an excessive force may be applied to the pelvic outer periphery, or the first fabric may turn over and the movement may be hindered.

  From this viewpoint, the subtraction value (E2−E1) is more preferably 3.6 to 11.6 N / cm, and most preferably 3.9 to 10.4 N / cm.

  From these combinations, except for swimwear, the elastic modulus along the waistline direction of the first fabric is set to 0.3 to 3.0 N / cm, and the elastic modulus along the waistline direction of the second fabric is 3 0.0-14.0 N / cm, the value obtained by dividing the elastic modulus of the second fabric by the elastic modulus of the first fabric is set to 2.0-25.0, and the elastic modulus of the second fabric It is preferable that the value obtained by subtracting the elastic modulus of the first fabric from 2.7 to 13.7 N / cm is set.

  In addition to the swimwear, the elastic modulus of the first fabric is set to 0.4 to 2.5 N / cm, the elastic modulus of the second fabric is set to 4.0 to 12.0 N / cm, The value obtained by dividing the elastic modulus of two fabrics by the elastic modulus of the first fabric is set to 3.0 to 20.0, and the value obtained by subtracting the elastic modulus of the first fabric from the elastic modulus of the second fabric is 3. It would be more preferable to set it to 6 to 11.6 N / cm.

  Other than swimwear, the elastic modulus of the first fabric is set to 0.6 to 2.0 N / cm, the elastic modulus of the second fabric is set to 4.5 to 11.0 N / cm, and the second fabric The value obtained by dividing the elastic modulus of the first fabric by 4.0 is set to 4.0-18.0, and the value obtained by subtracting the elastic modulus of the first fabric from the elastic modulus of the second fabric is 3.9. It would be more preferable to set it to ˜10.4 N / cm. In the most preferred example, the elastic modulus of the second fabric is set to 5.5 to 10.0 N / cm regardless of the type of competition.

  In the case of swimwear, it is preferable that the fabric is in close contact with the skin because water enters the swimwear and becomes a great resistance when the fabric is separated from the skin surface. For this reason, the elastic modulus of the first fabric is preferably high.

  On the other hand, when the elastic modulus E1 of the first fabric is increased, if the elastic modulus E2 of the second fabric is excessively increased, the body tightening force by the wear becomes too large. In the case of swimwear, the swimmer wears the swimwear with a large stretch. Therefore, although the elastic modulus of the second fabric itself is small, the force applied to the swimmer's waist is large.

  From such a viewpoint, in the case of swimwear, the elastic modulus of the first fabric is set to 1.2 to 3.5 N / cm, and the elastic modulus of the second fabric is set to 5.0 to 14.0 N / cm, A value obtained by dividing the elastic modulus E2 of the second fabric by the average value of the elastic modulus E1 of the first fabric is set to 1.5 to 7.0. From the elastic modulus E2 of the second fabric, It would be preferable that the value obtained by subtracting the elastic modulus E1 is set to 3.7 to 12.0 N / cm.

  In the case of swimwear, the elastic modulus of the first fabric is set to 1.5 to 3.0 N / cm, the elastic modulus of the second fabric is set to 5.5 to 10.0 N / cm, and the second fabric The value obtained by dividing the elastic modulus E2 by the elastic modulus E1 of the first fabric is set to 1.9 to 6.0, and the value obtained by subtracting the elastic modulus E1 of the first fabric from the elastic modulus E2 of the second fabric Would be more preferably set to 2.5-8.5 N / cm.

  In the case of swimwear, the elastic modulus of the first fabric is set to 1.7 to 2.8 N / cm, the elastic modulus of the second fabric is set to 6.0 to 9.0 N / cm, and the second fabric A value obtained by dividing the elastic modulus E2 by the elastic modulus E1 of the first fabric is set to 2.2 to 4.0, and the value obtained by subtracting the elastic modulus E1 of the first fabric from the elastic modulus E2 of the second fabric Is most preferably set to 4.3 to 7.2 N / cm.

  In swimwear, use a fabric with a lower elastic modulus (first fabric) for the front of the thigh where the muscle moves greatly, and use a fabric with a slightly higher elastic modulus (first fabric) for the lower abdomen, buttocks and back of the thigh. Also good. In this case, that is, when the first fabric and the second fabric include two or more kinds of fabrics having different elastic moduli, the elastic modulus of the fabric is defined as an average value not only in the swimwear but also in all the garments.

  In the present invention, the elastic moduli E1 and E2 set the pressure applied to the trunk when worn, and thus should be defined by the value of the wearing state. On the other hand, the elastic modulus of the fabric is different from the elastic modulus of the metal material and varies depending on the amount of elongation. Therefore, in the present invention, the elastic modulus is defined as follows in consideration of the reproducibility of the elastic modulus.

That is, as shown in the following formula (1), the elastic modulus means the magnitude of the load per unit elongation when the fabric is stretched by 20% for the fabric of unit width.
E = (F / W) / Δ (1)
E: Elastic modulus F: Load at 20% elongation W: Width of sample Δ: 0.2 (strain)
Since the elastic modulus in the present invention is the magnitude of the load per unit width of the fabric, the thickness of the fabric is ignored.
“Unit elongation” means the elongation per unit length of the fabric.
When the first or second fabric is a composite material, it is defined by a value measured in a composite state.

  On the other hand, the elastic part is locally high in the storage part formed in a bag shape by doubling the second fabric for storing the rubber-like belt or the rubber-like belt. However, among these members, the bag-shaped storage part that is difficult to measure is excluded from the definition of the elastic modulus in this specification.

  In a preferred embodiment of the present invention, an upper end portion of the first belt portion is provided with a storage portion that is continuous in a waistline direction, and the storage portion has the second fabric so that the second fabric is doubled. The dough is formed by folding back, and a rubber-like belt having rubber elasticity having elasticity in the waistline direction is housed in the housing portion.

  As described above, the elastic modulus of the upper end portion of the first belt portion having the storage portion and the rubber-like belt is significantly larger than the elastic modulus of other portions. Therefore, since the storage part and the rubber-like belt are continuous in the waistline direction at the upper end part of the first belt part, a large couple is exerted on the waist part when worn.

Here, the rubber-like belt having rubber elasticity is not only the case where the belt is formed of thread rubber or flat rubber, but also a belt formed by weaving thread rubber or impregnating and applying resin to the fabric. And a belt formed into a string or a band from a thermoplastic elastomer having a large elasticity.
“Rubber elasticity” refers to the property that the belt can be largely deformed (for example, the elongation at break is 100% or more), and the belt is restored to its original shape when the stress is removed.

  In a further preferred embodiment of the present invention, the elastic modulus of the rubber-like belt is set to 17 to 40 N / cm, and the width of the rubber-like belt is set to 2.0 to 3.5 cm.

  In this case, since the elastic modulus of the rubber-like belt is large and has a sufficient width, a large couple is exerted.

  The effects of the present invention are obtained by the pressure and moment that the wear exerts on the wearer's pelvis when worn. Therefore, in essence, the wear should be put on the mannequin, the pressure distribution on the surface of the mannequin should be measured, and this measured value should be used as a parameter. However, the measurement of the pressure distribution differs in the data obtained for different mannequins. Therefore, in this specification, the elastic modulus of the fabric is used as a parameter.

The average width in the vertical direction of the front portion of the belt is preferably about 3 to 12 cm, and more preferably about 4 to 10 cm.
On the other hand, the average width of the belt back portion in the vertical direction is preferably about 5 to 12 cm, and more preferably about 6 to 10 cm.

  If the width of the first belt portion is too large, it is difficult to obtain the offset effect. On the other hand, when the width | variety of a 1st belt part is too small, force will act too much locally on a wearer.

In the present invention, the front upper end line of the belt front portion is formed to be convex downward, and the rear upper end line of the belt back portion is formed to be convex upward or substantially horizontal. It is preferable.
Since the upper end of the first belt portion is formed in this way, the line of the upper end of the first belt portion draws a gentle curve from the center of the back surface to the center of the front surface through the side portion, and is natural. Line.

In this case, the lower end line of the belt front part is formed to be convex upward, and the lower end line of the belt back part is further formed to be convex upward. preferable.
In the case of this embodiment, the vertical width of the belt side portion is increased. When the vertical width of the belt side portion is large, the stability of the pelvis in the left-right direction increases.

In the present invention, the first belt portion covers at least a part of the upper anterior iliac spine in the vicinity of both ends of the front surface, covers a part of the iliopsoas muscle, and the belt back covers a part of the sacrum. Is preferred.
With such an arrangement, the first belt portion covers the bones and muscles to stabilize the pelvis, and the first belt portion presses the iliopsoas muscle to enhance the function of the iliopsoas muscle, which is an inner muscle. Become.

In this case, it is more preferable that the belt back portion covers the upper end of the sacrum or the vicinity thereof and does not cover the lower end.
When the belt back portion is provided at such a position, the offset amount between the force applied to the pelvis from the back surface and the force applied to the pelvis from the front surface is large. Accordingly, the pelvis tends to be in an upright posture.

Further, the belt side portion is preferably disposed below the iliac crest and above the greater trochanter.
Between the iliac crest and the greater trochanter, the belt side exerts a force on the gluteus medius, preventing the gluteus medius movement from side to side and enhancing the function of the gluteus medius. . As a result, the pelvis and lower limbs are stabilized in the left-right direction, and the exercise efficiency is improved.

  In this case, a line at the lower end of the belt side portion is formed so as to protrude downward as approaching the substantially center in the circumferential direction of the belt side portion, and the lowermost end of the belt side portion is the large end. Approaching the trochanter. It may be preferable that the height of the belt side portion is set to ½ or more and 4/5 or less of the distance from the greater trochanter to the iliac crest.

  The fact that the side of the belt presses the gluteus medius over a large area between the iliac crest and the greater trochanter enhances the function of the gluteus medius. If the belt side does not cover the greater trochanter, the leg movement will be smooth.

The present invention can be preferably used as swimwear.
By applying an offset force to the pelvis, a force that lifts the heavy lower leg upward acts on the pelvis during swimming. Therefore, the waist does not sink during swimming, and the posture is stabilized even if muscle fatigue occurs. As a result, the posture of the swimmer is likely to be an effective posture that is parallel and straight to the water surface, and the effective posture is easily maintained even if muscles are fatigued.

  In the case of swimwear, it further includes a pair of second belt portions formed of a fabric different from the first fabric, and an elastic modulus along a longitudinal direction of the second belt portion is larger than an elastic modulus of the first fabric. Each of the second belt portions has a first connecting portion in which an upper end of the second belt portion is connected to a lower end of the first belt portion at a thigh back portion outside the pelvis, and from the first connecting portion, It is preferably formed in a belt shape toward the inside of the knee.

  The function of assisting the function of hamstrings and gluteal muscles that extend the hip joint and the ability to rotate the hip joint by placing the second belt part on a virtual line connecting the pelvic outer side and the knee inner side of the thigh back improves . Further, by extending the hip joint, the lowering of the waist during swimming is suppressed.

  In the case of swimwear, it further includes a pair of third belt portions formed of a fabric different from the first fabric, and an elastic modulus along a longitudinal direction of the third belt portion is larger than an elastic modulus of the first fabric. The third belt portion is more preferably formed in a belt shape from the inside near the upper end of the front thigh toward the outside of the knee.

  By placing the third belt part on a virtual line connecting the inner side near the upper end of the front thigh and the outer side of the knee, the function of assisting the function of the adductor muscle group that inverts the hip joint and the inner joint of the hip joint are internally rotated. Function is improved. By turning the hip joint inward and inward, more water can be captured by the lower limbs and legs during a kicking action in water.

  In the case of running tights having legs that cover the lower side of the knee, the support part that is formed of the second fabric and covers the upper front surface near the knee, the support part, and the belt side part along the longitudinal direction of the leg. It is preferable to further include a connecting portion connected together.

  In this case, vibration of the thigh is suppressed by the support portion. Further, by connecting the support part to the belt part, lateral stability of the lower limbs is achieved. Furthermore, the rotation of the knee joint and the hip joint can be stabilized.

Test example 1, test example 2, test example 3, comparative example 1, comparative example 2 and comparative example 3 used in the test will be described.
In the following, “the elastic modulus of the rubber-like belt Gb” indicates the elastic modulus in a state where the first fabric F1 is superimposed on the front and back surfaces of the rubber-like belt Gb.

Test Example 1:
In Test Example 1, in the competition wear 1 of FIG. 1A, the elastic modulus along the waist direction R of the first fabric F1 is set to 1.1 N / cm, and the elastic modulus along the waist direction R of the second fabric F2 Is the wear set to 4.6 N / cm. The elastic modulus of the rubber-like belt Gb was 18.4 N / cm.

Test example 2:
In Test Example 2, in the competition wear 1 of FIG. 1A, the elastic modulus along the waist direction R of the first fabric F1 is set to 1.1 N / cm, and the elasticity along the waist direction R of the second fabric F2 The rate is set to 8.0 N / cm. The elastic modulus of the rubber-like belt Gb was 25.7 N / cm.
Accordingly, in Test Example 1, the pressure and couple applied to the subject by the first belt portion 10 (FIG. 1A) are set smaller than those in Test Example 2.

Comparative Example 1:
Comparative Example 1 is a wear in which the elastic modulus along the waistline direction R of the first and second fabrics F1 and F2 is 1.1 N / cm in the competition wear 1 of FIG. The elastic modulus of the rubber-like belt Gb of Comparative Example 1 was 6.1 N / cm.

Comparative Example 2:
The comparative example 2 used the well-known pants 100 shown to FIG. 1B, FIG. 3A, and FIG. 3B.
As shown in FIG. 1B, the pants 100 of Comparative Example 2 includes a third fabric F3, a fourth fabric F4, and a fifth fabric F5.

At the upper end of the pants 100, a rubber-like belt Gb is inserted over the entire circumference of the trunk of the pants 100.
As shown in FIGS. 1A and 1B, the front upper end line 14A of the pants 100 is set to be higher from the crotch C than the front upper end line 14 of the competition wear 1 of FIG. 1A. Therefore, the upper part of the wearer's pelvis Bh (FIGS. 5A and 5B) is tightened by the rubber-like belt Gb.
The maximum offset amount H1 of the upper end line of the pants 100 was about 3 cm.

As shown in FIGS. 3A and 3B, a fourth fabric F4 is used on the upper sides of both side surfaces 112 and the back surface 113 of the pants 100. For the belt front portion 111 of the pants 100, a fifth fabric F5 formed so as to protrude downward as it goes to the center is used.
The elastic moduli of the third fabric F3, the fourth fabric F4, and the fifth fabric F5 were 1.7 N / cm, 4.4 N / cm, and 4.9 N / cm, respectively. The elastic modulus of the rubber-like belt of Comparative Example 2 was 11.6 N / cm at the abdomen and 18.0 N / cm at the back.

Test Examples 3 and 4 and Comparative Example 3:
Test Example 3 is the men's swimwear of FIGS. 6A to 6C, and Test Example 4 is the girls' swimwear of FIGS. 10A to 10C. The elastic modulus of the first fabric of Test Examples 3 and 4 was 1.2 N / cm on the front surface, 3.3 N / cm on the back surface, and 6.7 N / cm on the second fabric. In addition, the rubber-like belt of Test Example 3 is thread rubber.
As Comparative Example 3, general swimwear was used.

Elastic modulus measurement method The elastic modulus of the fabric was measured according to the following specifications in accordance with JIS-L1018.
Testing machine: Universal material testing machine (Instron 5565 type)
Tensile direction: Wear circumference direction Tensile speed: 20.0 cm / min
Distance between chucks: 10.0cm
Fabric size: width 5.0cm, length 20.0cm
Sample size of rubber-like belts of Test Examples 1 and 2 and Comparative Example 1: width 2.5 cm, length 20.0 cm
Sample size of rubber-like belt of Comparative Example 2: width 3.0, length 20.0 cm
It was determined by measuring the magnitude of the load per unit width relative to the unit elongation when each sample was extended by 20%.

Short distance running test:
11A and 11B show the results of a short-distance running test using Comparative Example 1 and Test Example 1. FIG.
In this test, changes in running speed and propulsive force were measured with 14 male short-distance players as subjects.
As a result, as shown in FIG. 11A, the running speed was improved by 0.5% as an average value, and as shown in FIG. 11B, the driving force was improved by 3% as an average value.
This degree of improvement is equivalent to a reduction of 0.05 seconds when it is assumed that 100 m is run in 10 seconds.

Changes in kick behavior:
12A and 12B show the results of the kick operation test using Comparative Example 1 and Test Example 1. FIG.
In this test, changes in kick motion were measured using five male long-distance players as subjects.
As a result, as shown in FIG. 12A, the force in the lateral direction indicating the instability of the kick operation in Test Example 1 decreased as compared with Comparative Example 1. Further, as shown in FIG. 12B, the propulsion efficiency in Test Example 1 was improved by 8% in average value as compared with Comparative Example 1. In addition, the left and right sway of the hips during running was also reduced.

  Next, the following jump tests 1, 2, and 3 were performed. In this test, the subject jumped with a run, and the jump height was measured from the vertical displacement of the reflective marker attached to the subject's waist. The subject wearing each wear performed two jumps with two jumps as one set, for a total of four jumps.

Jump test 1:
13A and 13B show the results of jump test 1 using comparative example 1 and test example 2. FIG.
In Jump Test 1, the jump height was measured using a total of 8 male basketball players and 3 volleyball players as subjects.
As a result, as shown in FIG. 13A, the jump height of Test Example 2 was improved by 1 cm on average compared to Comparative Example 1. Further, as shown in FIG. 13B, the variation in the jump height in Test Example 2 was reduced as compared with Comparative Example 1, and the failure of the jump was reduced.

In this test, for the gluteus medius and the hamstrings, the strength output efficiency was measured by dividing the integrated value of the force when the subject kicked the floor by the amount of muscle activity.
As shown in FIG. 14A, the muscle strength exerting efficiency of the gluteus medius showed a large value in the order of Test Example 2, Comparative Example 1, and Test Example 1. In particular, Test Example 2 showed a muscular strength exerting efficiency about 1.5 times that of Test Example 1 and Comparative Example 1.
As shown in FIG. 14B, the muscular strength of hamstrings showed a large value in the order of Test Example 2, Test Example 1, and Comparative Example 1.
From these results, it can be seen that the efficiency of exerting each of the muscular strengths is large in the descending order of the couple applied to the pelvis.
This is because, during the jump, the activity of the gluteus medius M2 (FIG. 5B) that stabilizes the pelvis is promoted, and the pelvis stands upright so that the muscle becomes the optimal length, and as a result, mainly works in the jump. It is considered that the muscle strength efficiency of the gluteus musculature and hamstrings has improved.

Jump test 2:
In this test, five adult males who are doing competitive sports were subjects.
As a result, as shown in FIG. 15A, the average jump height was higher in the order of Test Example 2, Test Example 1, Comparative Example 2, and Comparative Example 1.

The wear of the comparative example 2 and the wear of the test example 1 are formed of cloth having the same elastic modulus. In addition, the offset force is applied to the body in both cases.
However, the difference of the experimental result of the comparative example 2 and the test example 1 has arisen, and the reason is considered.

The line 14A at the front upper end of the rubber-like belt Gb of the pants 100 used in Comparative Example 2 in FIG. 1B is arranged in a portion above the wearer's pelvis Bh.
On the other hand, the front upper end line 14 and the rear upper end line 15u of the rubber-like belt Gb of the competition wear 1 used in Test Example 1 are not arranged in a portion above the wearer's pelvis Bh.
The offset amount between the front upper end line and the rear upper end line of the rubber-like belt Gb of the competition wear 1 of Test Example 1 is the front upper end line and the rear upper end line of the rubber-like belt Gb of the conventional pants 100. It is larger than the offset amount with the line.

  That is, the competition wear 1 of the test example 1 is (1) the front upper end line of the rubber-like belt Gb is not arranged above the pelvis as compared with the pants 100. (2) The offset amount is the pants. There is a difference that the offset amount is larger than 100.

As described above, the competition wear 1 has the front upper end line of the rubber-like belt Gb not arranged above the pelvis, and the offset amount is large, so that there is a moment to erect the pelvis due to the offset couple. large. As a result, it is estimated that the pelvis tends to be in an upright posture.
On the other hand, in the pants 100, the line 14A at the front upper end of the rubber-like belt is arranged in a portion above the pelvis Bh, and the offset amount is small, so the offset couple is small. As a result, it is estimated that it is difficult to erect the pelvis.
From the above, it is considered that the competition wear 1 and the pants 100 have a clear difference in configuration, and the difference in the magnitude of the couple applied to the pelvis Bh has influenced the experimental results.

Next, the difference between the test results of Test Example 1 and Test Example 2 will be considered.
As described above, the elastic modulus of the second fabric F2 of Test Example 1 is 4.6 N / cm, the elastic modulus of the rubber-like belt Gb is 18.4 N / cm, and the elastic modulus of the second fabric F2 of Test Example 2 is 8 The elastic modulus of the rubber-like belt Gb was 25.7 N / cm.
Accordingly, the pressure and couple force applied to the pelvis Bh by the first belt portion 10 (FIG. 1A) of Test Example 2 is greater than the pressure and couple force applied to the pelvis Bh by the first belt portion 10 of Test Example 1.
When the pressure applied to the pelvis is large, the pelvis can be stabilized. Furthermore, since the couple applied to the pelvis is large, the pelvis tends to be in an upright posture.
As described above, Test Example 1 and Test Example 2 are different in the elastic modulus of the second fabric F2 and the rubber-like belt Gb, and it is considered that the difference in the pressure applied to the pelvis Bh and the magnitude of the couple affected the experimental results. It is done.

Jump test 3:
Next, the same jump test was conducted by wearing the respective wears of Test Example 1 and Comparative Example 1 with 8 general adult male subjects as subjects. As a result, as shown in FIG. 15B, the jump force was higher in Test Example 1 than in Comparative Example 1.

Swimming test:
The average value of the propulsion distance for one stroke during swimming was measured using seven male students and six female students of the university swimming club wearing the swimwear of Comparative Example 3 and Test Examples 3 and 4. As a result, as shown in FIG. 16A, the stroke length was increased by 2 cm on average.
Also, in Test Examples 3 and 4, about 70% of the athletes had their waists in the direction of the arrow in FIG. 16B, and therefore felt that the lowering of the waist was suppressed. Is estimated to have increased.

  The present invention can be used as various sports wear such as swimming, wrestling, and athletics.
