Description

Sports wear

The present invention relates to sports wear having at least a region covering the trunk, and more particularly to sports wear that stabilizes the trunk posture during exercise.

Conventionally, the trunk is generally known as the base part of all exercise movements, and by suppressing fluctuations such as bending of the trunk back and forth and collapse to the left and right during various exercise movements, It is known to improve overall exercise performance.

As one action based on this, the stabilizing action of the lumbar vertebrae due to the increase of intra-abdominal pressure is known. Here, the intraabdominal pressure indicates the pressure in the space in the abdomen surrounded by the abdominal muscles / back muscles group, and increases due to the activity of the abdominal muscles, particularly the internal and external oblique and lateral abdominal muscles. It has been proved from the viewpoint of sports medicine and biomechanics that when the intra-abdominal pressure rises, the abdominal cavity pushes the lumbar spine to the back side and the rigidity of the lumbar belt increases. It has been confirmed by various experiments that the posture stability of the trunk at the time increases.

The posture stability of the trunk contributes not only to the basic movements such as running and jumping, but also to the performance of cutting and turn movements found in ball games, and is an extremely important factor in sports movements.

For this reason, conventionally, a trunk-like supporter is strongly wound around the abdomen, or stretched taping is applied to the abdomen to obtain a trunk stability effect when the intra-abdominal pressure rises.

However, in the method of wrapping the belt-like supporter around the abdomen, in addition to the increase in weight, the belt-like supporter does not follow the movement of the trunk, which is a factor that hinders the natural movement especially in the operation of twisting the trunk There was a problem of becoming. On the other hand, in the method of applying elastic taping to the abdomen, specialized knowledge and skills are required for the taping operation, and it is physically difficult to tap the own abdomen. There was a problem that it was necessary separately.

In recent years, a lot of clothes called compression wear have been sold that can achieve similar effects just by wearing them without wearing belt-like supporters or taping.

Here, compression wear means changing the stretchability of the fabric in any part and controlling the wearing pressure, thereby reducing fatigue by promoting venous return, preventing damage by supporting around the joint, and correcting the shape of the soft tissue We expect various effects such as slimming and conditioning effects based on. Among these compression wears, there are those that are expected to improve exercise performance due to the pressure applied to the trunk.

For example, in Patent Document 1, an elastic warp knitting method in which the elastic modulus is seamlessly changed using a method of arbitrarily adjusting the elastic modulus of the fabric while having an isotropic property in the weft direction by knitting a second stitch. Sportswear using the ground has been proposed.

And in this patent document 1, as one of the above-mentioned sportswear for upper body sportswear, in FIG. 6, the elastic warp knitted fabric is used for the front part of the abdomen and the upper part of the back part, so that the body shape is corrected. It has been shown to improve the performance of exercise while having the function.

However, in the case of such upper-body sportswear, the above elastic warp knitted fabric is only arranged on the front of the abdomen on the front of the trunk. The entire lower trunk based on the activity of both the abdominal muscles / back muscles represented by the transversus abdominis, internal and external obliques, and standing spine muscles, which only affect the rectus abdominis muscle, which is considered to be almost unrelated. However, it was difficult to sufficiently stabilize the trunk posture during exercise.

Also, Patent Document 2 proposes an upper garment in which a hardly stretchable region is knitted in a lattice pattern on the front surface of the abdomen.

And in this patent document 2, it is shown that muscle activity is increased by the difficulty stretchable region knitted in a lattice shape on the front surface of the abdomen in the upper garment, which is suitable for rehabilitation and fat burning.

However, the upper garment shown in Patent Document 2 also has a non-stretchable region provided only on the front surface of the abdomen. It only acts on the rectus abdominis muscle, which is considered to be almost unrelated to the increase in internal pressure, and it cannot sufficiently apply the pressure to the entire lower trunk, which is important in exercise, and during exercise It was difficult to sufficiently stabilize the trunk posture.

Further, Patent Document 3 proposes clothing such as a swimsuit in which an inner core layer made of stretchable fabric that can be stretched on the inner surface of the base layer is provided in the region of the lower back from the front of the abdomen and the waist to the buttocks. ing.

And in this patent document 3, by providing the above inner core layer on the inner surface of the base layer in the region of the lower back from the front of the abdomen and the lower back to the buttocks, it helps smooth the abdomen and the buttocks, It has been shown to reduce shape resistance and provide additional support to improve trunk stability.

However, even in clothing such as a swimsuit disclosed in Patent Document 3, the inner core layer as described above is not provided over the entire circumference of the center of the trunk, and the entire center of the trunk is not provided. The circumference was not properly applied, and it was difficult to sufficiently stabilize the trunk posture during exercise.

An object of the present invention is to solve the above-described problems in sports wear including at least a region covering the torso, and in particular, a sport that can sufficiently stabilize the trunk posture during exercise. It is an object of the present invention to provide a service wear.

In the present invention, in a sports wear having a region covering at least the trunk, a pressure-applying portion that applies pressure over the entire circumference of at least a portion between the umbilicus and the superior anterior iliac spine at a position below the ribs. It was made to provide.

Like the sports wear of the present invention, when a pressure-applying portion that applies pressure over the entire circumference of a portion between the umbilicus and the superior anterior iliac spine is provided, at least the central part of the trunk is formed by the pressure-applying portion. The entire circumference is compressed and applied to the entire lower trunk based on the activities of both abdominal muscles / back muscles represented by transversus abdominis, internal and external obliques, and standing spine muscles, which are important in motor movements. The pressure acts sufficiently, and the back and forth and right and left shaking of the lower trunk during exercise is reduced. Further, since the pressure-applying portion is an area that does not reach the ribs, the upper trunk is hardly pressed and the breathing and arm swinging operations are not restricted.

In addition, in order to make the pressure applied to the entire lower trunk more fully, the above-mentioned pressure-applying portion is moved from the midpoint position between the umbilicus and the lower end of the radius to the umbilicus and upper anterior iliac spine. Can be provided so as to include the range of the midpoint position.

Further, when applying the pressure in the above-described pressure-applying portion, the pressure-applying portion can be made of a material having a stronger elongation stress than the body part other than the pressure-applying portion. For example, the pressure-applying portion Is made of a material that is less stretchable than the other body parts, and the stretchability at the pressure part is lower than the stretchability at the body parts other than the pressure part, so that the pressure at the pressure part is reduced. It can be made stronger than the body part other than the pressure part.

Further, the circumferential elastic deformation range in the pressure-applying portion is made larger than the elastic deformation range in the length direction, or the circumferential stretchability in the pressure-applying portion is set in the circumferential direction in the body part other than the pressure-applying portion. When the wear of this sportswear is worn, it is possible to reduce the stretchability in the length direction at the pressure-applying portion to be lower than the stretchability in the circumferential direction at the pressure-applied portion. Compared to the body part, a strong elongation stress is generated in the circumferential direction of the pressure-applying portion, and the pressure-applying portion can be appropriately applied with pressure. On the other hand, when the sportswear is attached / detached, the pressure-applying portion is prevented from extending in the length direction, and the sportswear can be easily attached / detached.

Here, in order to make the stretchability in the length direction in the pressure-applying portion lower than the stretchability in the circumferential direction in the press-fit portion, for example, the warp direction in the warp knitted fabric is the circumference of the pressure-applied portion. In this direction, the pressure-applying portion can be constituted by a warp knitted fabric, and at least one elastic yarn constituting the warp knitted fabric can be cut and knitted.

In addition, when the above-mentioned sports wear is provided with a pressure part and a body part other than the pressure part, when the pressure part and the body part other than the pressure part are sewn, the unevenness of the sewing part is caused. There is a possibility of rubbing on the skin and causing scratches, or rubbing on other wear and causing pilling. In addition, when applying a difference in stretchability between the pressure-applying part and the other body part by applying a resin-based coating agent or by partially discharging the resin impregnated in advance, the processing cost In addition, the production process may increase, and comfort during wear may be reduced due to changes in air permeability, water permeability, and friction coefficient. Furthermore, in these cases, since a change in the wearing pressure abruptly occurs at the boundary between the sewing part and the resin coating part, if the boundary and the body shape do not match, an undesired pressure distribution may occur. For this reason, when providing the above-mentioned sports apparel with a pressure part and a body part other than the pressure part, the pressure part and the body part other than the pressure part are constituted by a continuous warp knitted fabric. It is preferable that the boundary between the pressure part and the body part other than the pressure part is continuous without sewing.

In addition, when the pressure part and the body part other than the pressure part are configured as a continuous warp knitted fabric, the pressure part is formed in a band shape with a constant width so that knitting can be easily performed. Is preferred.

Further, in the sports wear described above, it is preferable to perform a process for increasing the frictional resistance on the skin surface side of the pressure-applying portion. In this way, when the sports wear is worn, the frictional resistance between the pressure-applying part and the skin increases, the displacement between the pressure-applying part and the skin decreases, and the pressure applied by the pressure-applying part is reduced. It works stably at the appropriate position. In addition, when performing the process of increasing the frictional resistance on the skin surface side of the pressure-applying part, for example, a material having a high friction coefficient is used for the material constituting the pressure-applying part, or a resin is used on the skin surface side of the pressure-applying part. Can be printed, or unevenness can be formed by knitting on the skin surface side of the warp knitted fabric constituting the pressing portion.

In addition, if the pressure applied at the pressure-applying portion is small, it is difficult to sufficiently obtain the above-described action due to the pressure-applied pressure. The feeling of wearing becomes worse. For this reason, it is preferable that the pressure applied in the pressure-applying portion is in the range of 0.7 to 1.2 kPa, more preferably in the vicinity of 1.0 kPa. The above-mentioned pressure value is a value measured using an air pack type sensor and using a contact pressure measuring device AMI3037-10 (manufactured by AIM Techno).

In the sports wear according to the present invention, as described above, the pressure-applying portion that applies the pressure to the entire circumference of the portion between the umbilicus and the superior anterior iliac spine is provided.・ Sufficient pressure is applied to the entire lower trunk based on the activities of both the abdominal muscles / back muscles represented by the internal and external abdominal oblique muscles and spine standing muscles, and the front and rear and left and right of the lower trunk during exercise Oscillation is reduced, and the trunk posture can be sufficiently stabilized during exercise, and the upper trunk is hardly pressed, and breathing and arm swinging movements are not restricted.

In the sportswear which concerns on said embodiment, it is the schematic back view which showed the state which has arrange | positioned the fastener between right-and-left spine standing muscles.

Next, sportswear according to an embodiment of the present invention will be specifically described with reference to the accompanying drawings. The sportswear according to the present invention is not particularly limited to those shown in the following embodiments, and can be appropriately changed and implemented within a range not changing the gist thereof.

FIG. 1 shows the positions of the torso of the human body X in the case where the pressure-applying portion 11 is provided on the sportswear 10, L is a line of the lower edge of the rib, P1 is a position of the umbilicus, and P2 is a lower end of the rib. P3 is the line at the upper anterior iliac spine, P12 is the line at the midpoint between the umbilicus and the lower end of the radius, and P13 is the line at the midpoint between the umbilicus and the upper anterior iliac spine. Show.

In the sportswear 10 of the embodiment shown in FIGS. 2 (A) and 2 (B), the pressure-applying portion 11 for applying the pressure is a line P12 at the midpoint position between the umbilicus and the lower end of the radius, When the sports wear 10 is worn when the sports wear 10 is worn over the entire circumference between the umbilicus and the line P13 at the midpoint position between the umbilicus and the superior anterior iliac spine, The pressure is in the range of 0.7 to 1.2 kPa so that a larger pressure is applied than the body part other than the pressure member 11.

In this way, the contact pressure provided over the entire circumference between the line P12 at the midpoint position between the umbilicus and the lower end of the radius and the line P13 at the midpoint position between the umbilicus and the superior anterior iliac spine. The entire circumference of the central part of the trunk is applied by the part 11, and the entire lower trunk, which is important in exercise, is sufficiently applied, so that the front and rear of the lower trunk during exercise Further, the swinging to the left and right is reduced, the trunk posture during exercise is sufficiently stabilized, and the pressure part 11 does not reach the rib, so that the upper trunk is hardly pressed. , Breathing and swinging motions are not limited.

Further, in the sports wear 10 of this embodiment, when the pressure applied to the pressure-applying portion 11 is larger than the body part other than the pressure-applying portion 11, the pressure-applying portion 11 is replaced with a portion other than the pressure-applying portion 11. It is made of a material that is less stretchable than the body part, so that the elongation stress in the pressure part 11 is larger than the body part other than the pressure part 11. In particular, since the stretchability in the circumferential direction of the pressure-applying portion 11 is lower than the stretchability in the circumferential direction of the body part other than the pressure-applying portion 11, A strong tension is generated in the direction, and a sufficient pressure can be applied to the entire lower trunk.

Moreover, in the sportswear 10 of this embodiment, the elastic deformation range in the circumferential direction of the pressure applying portion 11 is larger than the elastic deformation range in the length direction, and the stretchability in the length direction of the pressure applying portion 11 is increased. It is made lower than the stretchability in the circumferential direction. If it does in this way, at the time of attachment / detachment of this sportswear 10, it will be suppressed that the pressurization part 11 will extend in the length direction, and it will become difficult to attach / detach, and attachment / detachment of sportswear 10 can be performed easily.

Here, as described above, the elastic deformation range in the circumferential direction in the pressure-receiving portion 11 is larger than the elastic deformation range in the length direction, and the stretchability in the length direction in the pressure-receiving portion 11 is lower than the stretchability in the circumferential direction. In order to obtain the sports wear 10, for example, as shown in FIG. 3, a three-ply warp knitting machine is used, and 44 dtex PET yarn is applied to the front heel at the body part other than the pressure-applying portion 11. Using cord knitting and denby knitting using 33 dtex polyurethane elastic yarn on the back heel, while the pressure part 11 is the same as the body part other than the pressure part 11, 44 dtex PET is applied to the front heel. Cord knitting using yarn, Denby knitting using 33 dtex polyurethane elastic yarn on the back bag and 44 dtex polyureta on the middle bag Perform the chain knitting an elastic yarn, so that the warp direction of the thus organized warp knitted fabric is in the circumferential direction.

In this way, the stretchability in the circumferential direction of the pressure-applying portion 11 is the stretchability in the circumferential direction of the body portion other than the pressure-applying portion 11 by the comb knitting with the polyurethane elastic yarn knitted only on the pressure-applying portion 11. Accordingly, it is possible to obtain the sports wear 10 in which the stretchability in the length direction of the pressure-applying portion 11 is lower than the stretchability in the circumferential direction.

Further, by using a three-ply warp knitting machine as described above, it is possible to provide the pressure-applying portion 11 in a band shape with a constant width, and the boundary between the pressure-applying portion 11 and the body part other than the pressure-applying portion 11. Can be easily knitted at the same time so as to be continuous without sewing.

And when the boundary of the body part other than the pressure part 11 and the pressure part 11 is continuously knitted without sewing in this way, the body part other than the pressure part 11 and the pressure part 11 is sewn. In this way, the unevenness of the sewing part does not rub against the skin and cause scratches, or it causes other parts to wear, causing pilling, etc., and the wearing pressure changes abruptly with the sewing part as a boundary. Thus, the wearing feeling is prevented from being impaired.

Further, in the sports wear 10 of this embodiment, as shown in FIGS. 4A and 4B, the unevenness 11a by knitting is provided on the skin surface side of the pressure-applying portion 11, and the unevenness 11a The frictional resistance on the skin surface side of the pressure contact portion 11 is increased. When the frictional resistance on the skin surface side of the pressure-applying part 11 is increased in this way, the displacement between the pressure-applying part 11 and the skin when performing exercise motion while wearing is reduced, and the pressure applied by the pressure-applying part 11 is reduced. Will act stably at the appropriate position. Further, in the case where the unevenness 11a is provided by knitting as described above, there is no sense of discomfort at the time of wearing as in the case where the resin is printed on the skin surface side of the pressure-applying portion 11 to increase the frictional resistance.

In the sports wear 10 according to the above-described embodiment, the pressure-applying portion 11 for applying the pressure is formed between the line P12 at the midpoint position between the umbilicus and the lower end of the radius, and the umbilicus and the superior anterior iliac spine. It is provided in a band shape with a constant width over the entire circumference between the line P13 at the midpoint position between them, but at least below the umbilicus and the superior anterior iliac spine at a position below the line L at the lower edge of the radius. In a range including a part between the widths, the width can be increased or decreased.

Moreover, according to the kind of exercise | movement which wears this sportswear 10, it is also possible to change suitably the width | variety of said compression part 11 in the circumferential direction, for example, FIG. 5 (A), (B ), The width of the pressure-applying portion 11 in the front abdomen is made larger than the other portions, or the width of the pressure-applying portion 11 in the back waist as shown in FIGS. 6 (A) and 6 (B). Can be made larger than the other parts, and as shown in FIGS. 7A and 7B, the width of the pressure-applying portion 11 on both sides can be made larger than the other parts.

Further, a fastener can be provided so that the sportswear 10 as described above can be easily attached and detached. In this case, in order to prevent the fastener from directly contacting the skin and causing scratches, FIG. As shown in FIG. 8, it is preferable to arrange the fastener 12 between the right and left spine standing muscles.

In this embodiment, an example of the sleeveless sports wear 10 is shown, but a sleeve may be provided.

Next, as shown in the above-described embodiment, the pressure-applying portion for applying the pressure is set between the line P12 at the midpoint position between the umbilicus and the lower end of the radius, and between the umbilicus and the superior anterior iliac spine. When using sportswear that is provided in a band with a constant width over the entire circumference between the point position line P13 and wearing this sportswear, compared to not wearing this sportswear, It will be clarified based on experiments that fluctuations in the front-rear direction and the left-right direction during movement are suppressed.

Here, when the above-mentioned sports wear was worn, the pressure applied to the pressure-applying part was 1.0 kPa, and the pressure applied to the body part other than the pressure-applied part was 0.3 kPa.

And, in the acceleration phase of about 10 m from the start where the trunk sway is the largest in full power sprinting motion, as the amount of swaying in the abdomen below the rib lower end and the chest above the rib lower end, The angle change in the left-right direction was measured when the above-mentioned sports wear was worn and when it was not worn, and the results are shown in Table 1 below. In addition, about the angle change to the front-back direction and the left-right direction, 250 frames per second were measured using the optical reflection type motion capture system Vicon (made by Vicon-Motion-systems-Inc.).

As a result, there was almost no difference in the amount of swaying in the front-rear direction and the left-right direction in the chest of the upper trunk, but when the sports wear was not worn, the lower body is important in exercise Comparing the amount of swaying in the front and back direction and the left and right direction in the abdomen of the trunk, when wearing sports wear, the amount of swaying in the front and back direction and left and right direction is greatly reduced compared to when not wearing it, There is a significant difference between the two, indicating that the trunk posture can be sufficiently stabilized during exercise.
