Description

  The present invention relates to an exercise spat that is worn in a state of being in close contact with the surface of the lower body of the wearer. The present invention relates to an exercise spat that can strengthen the exercise function of the gluteal muscle.

  Conventionally, as for exercise spats, various tights and spats for the purpose of improving exercise functionality and protecting muscles and joints are known.

  The lower limb protective clothing of Patent Document 1 below is a clothing made of a stretchable fabric having at least a lower body portion having a leg length exceeding the patella portion, and the clothing is partially tightened. It has a strong part, passes through the greater trochanter from at least the greater trochanter as the strong part of the tightening force, and further on the vicinity of the boundary between the biceps femoris and the intestinal shin ligament to support the biceps femoris Protective clothing for lower limbs with a strong tightening force part that passes through the vicinity of the lower part of the tendon of the biceps femoris muscle diagonally and to the vicinity of the upper end of the tibia without crossing the muscle abdomen of the biceps femoris It is. This lower limb protective clothing can protect the lower leg during various sports such as baseball, rugby, soccer, etc., especially by supporting hamstrings, which are muscles on the back of the thigh, while maintaining muscle balance and knee Its purpose is to provide protection and movement support for the entire joint and hip joint.

  The lower garment of the following Patent Document 2 has a front part, rear part, outer part, rear waist take-out part, and inner part that make up a pattern adapted to the movement form, and supports the outer knee on the outer surface side of the outer part and the front part. The outer knee support part is sewn, the inner knee support part supporting the inner knee part is stitched outside the inner part and the front part, and a gap is provided between the tips of both support parts, and the front part, the rear part and the inner part Is formed of a tricot knitted fabric having a normal stretch ratio, and the outer portion, the rear waist take-out portion, and both support portions are formed of a tricot knitted strong stretch fabric having a larger elongation than the front portion. The lower garment can be structured to be sufficiently adaptable to the form of movement and can reinforce the mutual movement of the waist and legs without causing compression or pulling. The medial and lateral collateral ligaments of the knee joint can be supported.

Japanese Patent No. 3012819 Japanese Patent No. 3241608 Japanese Patent Laid-Open No. 11-12814

  However, the lower limb protective clothing of Patent Document 1 supports hamstrings, which are muscles on the back of the thigh, to maintain the balance of the muscles, and to protect and assist the entire knee joint and hip joint. The main function of the lower garment of Patent Document 2 is to reinforce the mutual movement of the waist and legs and to support the medial collateral ligament and lateral collateral ligament of the knee joint by both support parts. The taping function tights of Patent Document 3 have the same action as that for protecting the thigh ligament, the inflated shin ligament and the Achilles tendon in sports taping.

  These are intended for exercise support by the waist, joint protection, and material placement methods during exercise, but do not have a function to assist the contraction of the greater anterior muscle, for example, in short distance running in athletics.

  In order to solve the above-described conventional problems, the present invention provides an exercise spat that can enhance the exercise function of the greater gluteal muscle in a sport that needs to exhibit instantaneous power.

The exercise spats of the present invention are made of stretch material, and are worn in a state of being in close contact with the surface of the lower body of the wearer, and include the first type material and the second type material. Spats,
The tightening force of the first type material is stronger than the tightening force of the second type material,
The first type of material is disposed at a position that covers at least a part or all of both greater gluteus muscles,
The second type material is arranged in an area other than the area where the first type material is arranged.

  In the present invention, a stretch material having a strong tightening force as the first material (hereinafter also referred to as “strong tightening material”) is closely attached to a position that covers a part or all of at least both greater gluteal muscles of the human body. For example, in the case of athletics, especially when short-distance power is required, such as when running at short distances, it helps the contraction of the greater gluteus muscle when the ground is kicked and moved forward with a foot. Exercise spats that can exert instantaneous power can be realized. That is, the strong tightening material contracts in accordance with the contraction of the greater gluteus muscle, so that the motor function of the greater gluteus muscle can be synergistically enhanced to exert a stronger instantaneous force.

  The running motion is a typical cyclic motion in which repeated motion is performed. If attention is paid to the movement of one leg, the running movement is roughly divided into a grounding period in which the foot is grounded and a swinging leg period in which the foot is not grounded. Further, the ground contact period is divided into a first half in which the kick force in the forward direction works and a second half in which the kick force in the backward direction works, based on the relationship between the center of gravity of the body and the support foot. Similarly, the free leg period is divided into a first half until the leg comes directly below the center of gravity of the body after the foot has taken off, and a second half swinging forward from the center of gravity.

  The above operation will be described with reference to FIG. 7 is a ground contact period, 8 to 10 and 1 are the first half of the swing period, and 2 to 6 are the second half of the swing period. Since the ground contact period 7 is extremely short, it cannot be divided into the first half and the second half in FIG.

  Each joint of the lower body exerts particularly great power during the ground contact period 7, and muscles such as greater gluteal muscles also contract and exert great power. Therefore, the contraction of the greater gluteal muscle can be assisted particularly by the placement of the strong tightening material in a position covering the greater gluteal muscle. That is, the portion of the strong tightening material contracts in accordance with the contraction of the greater gluteal muscle, so that the motor function of the greater gluteal muscle can be synergistically enhanced to exert a stronger instantaneous force.

  Furthermore, in the first half 8-10 of the swing leg period, since the leg swings backward, the skin surface of the part contracts, but the strong tightening material also assists with this contraction, resulting in quick backward movement as a result. Swing is possible. However, since the foot is not grounded, a great effect cannot be expected.

  On the other hand, in the second half of the free leg period 2-6, the tightening force of the strong tightening material is in a state where the swing of the leg forward is hindered, but the joint does not need to exert great power because the leg is not grounded. Therefore, the influence that hinders the operation is not so great.

  From the above, when the running motion is considered as a total, the effects of the first half and the second half of the swing leg period are almost offset, and as a result, a large movement assist effect in the ground contact period can be obtained.

  Next, the muscles of the lower body of the human body will be described with reference to FIGS. The large gluteal muscle 70 is present in the buttocks, the middle gluteal muscle 71 is above it, and the intestinal shin ligament upper part 73 and the thigh fascia latae 72 are present in this order. 74 is the upper adductor upper part. In the spats for exercise of the present invention, a strong tightening material is disposed on the greater anterior muscle 70 or the greater anterior muscle 70 and the intermediate anterior muscle 71. Placing a strong fabric material in this area can effectively assist muscle contraction. In addition, a stretch material having a weak tightening force (hereinafter referred to as “weakly tightened material”), which is a second type of material, is disposed outside the region where the strong tightened material is disposed.

  The exercise spats of the present invention are suitable for sports based on running.

  In the present invention, in order to create an “almost close contact” state, the peripheral direction is 50% or more and 110% or less, more preferably 70% or more and 95% or less, and the length is 75% or more and 100% with respect to the naked size of the human body. % Or less, more preferably 85% or more and 100% or less to form exercise spats. Of course, since the size of the human body varies among individuals, the above ratio is a guide.

  In the present invention, the “main component” refers to a main fabric portion constituting the exercise spats, that is, a fabric covering the waist and at least the thigh. In addition, the strong tightening material is disposed at a position covering at least a part or all of both greater gluteal muscles. Furthermore, you may arrange | position in the position which covers a part of at least middle gluteal muscle.

  The exercise spats may be formed to cover up to the knee, below the knee, or to the ankle. In the case of covering up to the knee or ankle, these fabrics are arbitrarily arranged with a strong tightening material and a weak tightening material as necessary.

  The strong tightening material and the weak tightening material are preferably integrated by sewing. However, in the case of a weft knitted fabric, it can be integrally knitted as will be described later.

  The strong tightening material and the weak tightening material of the present invention are stretch materials, and the elongation rate when the material is 4.9 N (500 gf) in a width of 5 cm is 5% or more and 30% in the first type material in the direction of the background. It is preferable that the range of less than 30% is the range of 30% or more. In addition, when the elongation of 17.7 N (1800 gf) weight in a 5 cm width is A, the value of the first type of material is A, and the value of the second type of material is B, A is 30% in both the longitudinal direction. More than 80% and B is preferably 80% or more.

In order to obtain such stretch characteristics of each portion, as will be described later, for example, when an elastic yarn is used as a constituent yarn of a knitted fabric or a woven fabric, the following means can be taken as an example.
(1) The composition ratio of the elastic yarn is made higher in the strong tightening material than in the weak tightening material.
(2) Increase the fineness of the elastic yarn in the strong tightening material compared to the weak tightening material.
(3) In the case of a woven fabric, the warp and / or weft density is increased, and in the case of a knitted fabric, the knitting density is increased as compared with a weak tightening material.
(4) A woven fabric or a knitted fabric is produced with a high tension material having a higher tension of the elastic yarn than a weak tension material.
(5) Fabrics or knitted fabrics are manufactured by making the fabric thicker than the weakly tightened material.

  The stretch material of the present invention is preferably at least one fabric selected from a 2-way stretch knitted fabric and a 2-way stretch woven fabric that expand and contract in the machine direction and the transverse direction.

  The two-way stretch knitted fabric or woven fabric may include polyester fiber yarns and elastic yarns as main component constituent yarns, or nylon fiber yarns and elastic yarns as main component constituent yarns. As another configuration, cotton (cotton) and elastic yarn may be used as the main component constituting yarn. Here, the main component constituting yarn means that the total of both components is 80% by weight or more. When polyester fiber yarn is used, it is easy to dry even with sweat. When nylon fiber yarn is used, the knitted fabric has a soft touch.

  The knitted or woven fabric may have any structure. As the woven fabric, a plain weave, a diagonal weave, and a satin weave, which are generally well known, may be a changed weave. Further, a knitted fabric knitted by a Russell warp knitting machine generally well known as a knitted fabric, a knitted fabric knitted by a tricot warp knitting machine, a knitted fabric knitted by a knit weft knitting machine, or the like may be used. For example, a knitted fabric having a half structure knitted by a tricot warp knitting machine or a knitted fabric having a power net structure knitted by a Russell warp knitting machine can be used. As the knitted weft knitted fabric, any structure such as a flat knitting (tengu knitting), a rubber knitting, a pearl knitting, a smooth knitting (double-side knitting) may be used. The knitted fabric knitted by the knit weft knitting machine may be a knitted fabric knitted by a circular knitting machine or a flat knitting machine. In the case of the weft knit, it is also possible to integrally knitting the weak tightening material and the strong tightening material without requiring sewing. For example, there is an apparatus called “FIRST-X” of a flat knitting machine (Shimae Seiki Seisakusho), which can be used to knit the waist and both legs at the same time to produce a knitted product without sewing.

  In addition, a combination of strong and weak tightening materials is seamlessly knitted into a cylindrical shape with a device called "seamless body inner knitting machine" under the full computer control of Santoni, Italy. It is also possible to do.

  The woven fabric or knitted fabric preferably uses at least a part of elastic yarn having elasticity such as polyurethane yarn.

  The elastic yarn is preferably at least one selected from a polyurethane elastic yarn and a polyester elastic yarn. This is because it is highly stretchable and suitable for sports clothing. The elastic yarn may be either a bare yarn (bare yarn) or a covered yarn whose surface is coated with polyester fiber or nylon fiber.

  A fabric using a high crimped false twisted yarn such as polyester or nylon which has been subjected to high crimped false twisting to give stretchability is also possible for at least part or all of the fabric. It is also possible to simply use a plurality of the stretchable knits. Furthermore, the stretchable knitted fabric is laminated into a two-layer laminate fabric, and a stretchable polyurethane sheet is sandwiched between the stretchable knitted fabric and laminated into three layers. A layer laminate fabric can also be used.

  Next, as a method of giving the fabric material a “strong” or “tight” tightening force to obtain a strong tightening material and a weak tightening material, a mixture ratio of polyurethane yarn and high crimped false twisted yarn (hereinafter referred to as stretch yarn) is used. The “large” and “small” of each can give the fabric material a “strength” tightening force. As a method of changing the blend ratio, changing the thickness of the stretch yarn to “thin and thin” gives the blend ratio “large” or “small”. There is a way to get a “large” or “small” mix ratio. It is also possible to change the knitting density to “sparse / dense” when the mixing ratio of the stretchable yarn is constant. In addition, using a fabric with different types of stretch yarns, using a laminated fabric and a non-laminated fabric, or changing the number of layers of the same fabric will also give the fabric a “strength” tightening force. It is possible to have it.

  The “strength” tightening force of the strong tightening material and the weak tightening material can be confirmed by the magnitude of the stretch rate of the fabric at a constant load. That is, a fabric having a strong tightening force has a low elongation rate, and a fabric having a weak tightening force has a high elongation rate.

  In the present invention, the tightening force refers to the resistance of the material to elongation.

The measuring method of the stretch ratio representing the stretchability and the tightening force is a TENSILON universal type tensile tester (UTM-III-200, manufactured by Toyo Baldwin), the tensile strength is 20 cm / min, and the size of the sample fabric is The width was 5 cm, the length was 30 cm, and the holding interval was 20 cm. The weight for measuring the tightening force was 4.9 N (500 gf), the weight for measuring the stretch property was 17.7 N (1800 gf), and the measurement was made in the direction of the background of the fabric material. Hereinafter, the expansion ratio used in the description of the examples is a measurement result by this measurement method.

  In the exercise spats according to the present invention, the strong tightening material and the weak tightening material are integrated by sewing or bonding to form an exercise spats.

  Examples of sewing methods include lock stitching, chain stitching, 1-needle overlock, 2-needle overlock, sewing with a sewing machine that forms a seam, etc. It is not limited to these. However, it is desirable to adopt a one-needle overlock, a two-sewing overlock, and a flat seamer that have a stretch property and are less likely to cause discomfort when worn.

  As the bonding method, paste two types of fabrics (members) that you want to integrate, melt them with heat, and paste them with a heat-meltable seam tape made of resin, such as polyurethane or silicone, which penetrates and solidifies after cooling. Although there is a thermocompression bonding method in which the fabric can be bonded by sandwiching between the fabrics and heat-pressing, it is desirable to provide a stretch property similar to sewing so as to eliminate the uncomfortable feeling at the time of wearing.

  The athletic spats of the present invention can be applied not only to athletics but also to various sports such as golf, tennis, badminton, squash, hockey, jogging, soccer, and rugby.

  Hereinafter, an embodiment of the exercise spats according to the present invention will be described with reference to FIGS. 3A to 3C. 3A is a front view of the exercise spats, FIG. 3B is a side view, and FIG. 3C is a back view. The spats for exercise of this example constituted pants with each member of the center front part 11, the front thigh part 12, the rear upper part 13, the rear center part 14, the rear thigh part 15, and the waist cord 16 used at the time of wearing. The respective parts are arranged symmetrically. In this embodiment, the members are integrated with each other by sewing to form pants. As a sewing method, a flat seam sewing machine was used, polyester spun-like filament yarns were used as needle yarns, wooly nylon yarns were used as upper and lower yarns, and seams with flat seams were sewn.

The rear center portion 14 is made of a strong tightening material (indicated by a hatched portion in the drawing) and is arranged in a partial region of the wearer's major and middle gluteal muscles. The strong tightening material is a polyester filament twin yarn with a fineness of 136 dtex and a bare tentacle structure using a polyurethane bare yarn with a fineness of 64 dtex. The blend ratio is 85% polyester, 15% polyurethane, A circular knitting machine with a gauge number of 30 G was used. The elongation at the time of 4.9N (500 gf) load representing the tightening force was 20% in the warp direction and 25% in the weft direction. The elongation at the time of 17.7N (1800 gf) load representing the stretchability was 60% in the warp direction and 70 in the weft direction. The weight (unit weight) per unit area was 320 g / m ² .

The central front part 11, the front thigh part 12, the rear upper part 13 and the rear thigh part 15 were made of a weak tightening material. Weakly tightened materials are polyester filament yarn with a fineness of 68 dtex and bare bear tissue using polyurethane bare yarn with a fineness of 36 dtex. The blending ratio is 85% polyester, 15% polyurethane, round A knitting machine with a gauge number of 30 G was used. The elongation at the time of 4.9N (500 gf) load representing the tightening force was 90% in the warp direction and 70% in the weft direction. The elongation at the time of 17.7N (1800 gf) load representing the stretchability was 190% in the warp direction and 80% in the weft direction. The weight (unit weight) per unit area was 190 g / m ² .

  In this example, in order to create a “substantially close contact” state, 80% in the peripheral direction and 90 to 95% in length were prepared as a guide for the naked size of the human body.

  In order to verify the effect of the present example, the following experiment was conducted on five sprinters of athletics.

  That is, the lower limb muscle activity amount obtained from the measurement of the lower limb electromyogram at the time of running at 25 km / h using a treadmill is the same as that of the example product of the present invention and the comparative example product (the same shape as the present example, all sites Comparison was made using spats made of weakly tightened material) and conventional running pants (trunks using polyester tricot).

  The electromyograms of the lower limbs are derived from the outer front of the thigh, the front of the thigh, the center of the front of the thigh, the center of the front of the thigh, and the wide thigh so that the activities of the outer vastus, medial vastus muscle, rectus femoris, biceps femoris, and greater calf muscle can be derived, respectively. Measurement was performed with electrodes attached to the center and the buttock.

  All measurements were performed on the right leg, and the integrated value of the electromyogram from the landing of the foot to the next landing was taken as the amount of muscle activity. If there is an effect of the present embodiment, the amount of muscle activity when the present embodiment is worn should be low even when traveling at the same speed.

  As a result, as shown in FIG. 4, when comparing the amount of muscular activity when wearing the conventional general running pants as 100%, this example is more muscle than either the comparative example product or the conventional general running pants. The amount of activity was low, and especially in the buttocks, the muscle activity amount was 88.4% lower than that of the conventional general running pants. FIG. 4 is an average value of five testers.

  From this result, it is clear that the strong tightening portion arranged in the collar portion in this embodiment assists the running operation. Moreover, although this result is a comparison of the amount of muscle activity at the same speed, it can be expected that the vehicle can run at a higher speed if it exhibits muscle activity similar to that when running pants when wearing this embodiment.

  In addition, when all subjects wear it, there is less fatigue, and when the force is needed, it will help the contraction of the greater gluteal muscles when kicking the ground with the foot to move forward, and exert a stronger force I was able to confirm that it was possible. The feeling of wearing was good and well received.

  In the above-described embodiment, the spats are formed by the members of the center front portion 11, the front thigh portion 12, the rear upper portion 13, the rear center portion 14, the back thigh portion 15 and the waist cord 16 used at the time of wearing. The shape of each region is not limited to this as long as the fabric materials having the respective tightening forces are arranged in the region. Further, in the above-described embodiment, the length of the exercise spats is the length up to the above-knee position, but of course it is not limited to this, and the position below the knee is within the range in which the object of the present invention is achieved. The length of the spats for exercise such as the ankle position may be arbitrary. 1A to 1C are three-dimensionally resembling the wearing state, but some shape changes may be made depending on the wearer's body shape and the like.
