DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sports clothing, and by partially changing the pressure exerted by the clothing on the human body surface, that is, "clothing pressure", to increase concentration during exercise and reduce fatigue. It relates to sports clothing that can be reduced, and mainly to long tights.

[0002]

2. Description of the Related Art In the technical field of sports clothing, various types of materials using stretchable fabrics have been developed from the viewpoint of functionality. For example, long tights used mainly in athletics, one-piece-style clothes used in skiing and skating are typical examples. Among them, long tights have been used for the purpose of keeping warm, but recently, some have been provided with various functions.

[0003] For example, in JP-equitable 6-41641 made to have a taping function tights, have been described that similar effects as taping can be obtained by wearing, there is inexperienced person to taping techniques Even if the necessary parts are appropriately taped, the same function can be obtained, and it is effective in preventing and treating injuries.

Further, Japanese Utility Model Laid-Open No. 5-225004 discloses a stocking for a long-distance runner. The stockings are circularly knitted integrally from the panties to the Achilles tendon, increasing clothes pressure from the panties to the Achilles tendons, improving blood circulation of the feet, and assisting the knee flexing and stretching movements with the elasticity of the stockings. As a result, there is a feature that the movement of the foot is lightened, fatigue is reduced, and the bending and stretching of the foot is speedy and the speed is increased.

Japanese Unexamined Patent Publication (Kokai) No. 3-279403 describes a stocking in which the clothing pressure is gradually reduced from the arch to the thigh, and the tightening force of each part is varied. , Giving a good fit and an excellent wearing feeling. Further, general sports tights have a substantially uniform tightening pressure.

[0006]

However, these conventional techniques have the following problems to be solved. In other words, the tights described in Japanese Patent Publication No. 6-41641 are effective in preventing and treating injuries, but because the stretching direction of the muscles is restrained in the same manner as taping by using a cloth with a strong tightening force,
Movable range of the crus and the thigh is limited, it was also to restrict maneuverability.

The stockings described in Japanese Utility Model Laid-Open No. 5-25044 can be expected to improve the blood circulation of the feet by changing the clothing pressure, but the elastic modulus of the stockings described is generally used for tights for sports. This is equivalent to the elastic modulus of a two-way tricot formed by warp knitting, and a special effect beyond the above-described effect of improving blood circulation cannot be expected.

The pantyhose described in Japanese Patent Application Laid-Open No. 3-279403 provides a fit and an excellent feeling of wearing, but has no effect in reducing fatigue and the like. Also,
Conventional sports tights and skating one-pieces have no special effect other than heat retention.

In general, the sequence of exercise is described in the following order: warm-up, training or competition, and then cool-down. The characteristics required of sports clothing in each process include warming up muscles, increasing concentration, and preparing for the next full-scale exercise at the time of warming-up, in order to prevent breakdowns and enhance athletic performance. Also, when training or competing, your clothes should not impede your movement,
It is necessary to be able to maintain a high concentration and to reduce fatigue as much as possible. Furthermore, at the time of cool down,
It is necessary to improve blood circulation in order to eliminate fatigue mainly caused by lactic acid accumulated in muscles. However, no tights satisfying all of these functions have been invented.

[0010]

SUMMARY OF THE INVENTION A sport garment according to the present invention has been developed in order to solve the above-mentioned problems, focusing on the following points. In other words, when it comes to sports long tights, it is empirical to wrap a gaiter around the lower leg for a long time to improve blood circulation of the lower leg and reduce fatigue by appropriately pressing the lower leg. It is well known from the facts. Therefore, the purpose of reducing the fatigue of the lower leg can be relatively easily achieved by appropriately pressing the lower leg. In recent years, research on the measurement of so-called "CNV" has shown that moderate pressurization contributes to the improvement of concentration, etc. in relation to the effect of stimulation on the legs and the like on the nervous system such as concentration and attention. It has been found. Furthermore, since the thigh and the lower leg have a boundary line below the knee and the clothing pressure on the lower leg is higher than that of the thigh, helping the blood that tends to stay in the lower leg to return to the heart, It has the effect of reducing fatigue and also reducing the burden on the heart.

Therefore, by changing the clothing pressure in various ways and measuring the brain potential related to concentration and the like, the clothing pressure on the thigh in the sports long tights is reduced by 15% when worn.
A ~30gf / cm ^2, clothing pressure of the lower leg portion is concentration and attention when set to be 60~80gf / cm ² that is increased is clarified when worn.

Further, in configuring the long tights according to the present invention, the material forming the lower leg is made of a material having a higher tension than the material forming the thigh, thereby exercising the exercise performance. This makes it possible to obtain the above-mentioned difference in clothing pressure, and to obtain long tights that are not unsightly in appearance and excellent in fashion.

Next, a one-piece type garment used in skiing and skating competitions, and a garment used in various competitions such as cycling competitions and rowing competitions, which are made of stretchable fabric and are closely attached to the body for sports Also in clothes, by changing the clothes pressures of the thighs and lower thighs, upper arms and lower arms, and abdomen and chest, it is possible to exert the same operational effects as the above-mentioned long tights.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The long tights according to the present invention
As shown in FIGS. 3 and 4, long tights made of a material having elasticity, and the material constituting the lower leg is more strained than the material constituting the thigh with the line immediately below the knee joint as the boundary line. By increasing the force, the clothing pressure on the lower leg is made higher than that on the thigh. Specifically, the clothing pressure on the thigh becomes 15 to 30 gf / cm ² when worn, and the clothing pressure on the lower leg is increased. Is configured to be 60 to 80 gf / cm ² when worn. Here, the thigh of the long tights according to the present invention is a pubis muscle, a long adductor muscle, a group of adductor muscles composed of thin muscle and adductor muscle, sewing muscle, rectus femoris, middle vastus, The part covering the quadriceps femoris (extensor thighs) consisting of the vastus lateralis and medial vastus, flexor thighs consisting of the semimembranosus, semitendinosus and biceps femoris, and the lower leg of long tights The part is a group of extensor leg muscles including the peroneus longus, tibialis anterior, gastrocnemius, soleus, short peroneus, and extensor digitorum longus, and the peroneus, soleus, flexor pollicis longus, flexor longiscus and tibia It refers to the site that covers the crus flexor group consisting of muscles.

The above clothing pressure is measured by a pressure sensor having a thickness of 0.6 mm and a diameter of 6 mm (PS- manufactured by Kyowa Dengyo Co., Ltd.).
A pressure-sensitive element (2.0 mm thick) obtained by laminating and integrating an elastic sheet made of silicone or the like and a thin metal plate having a diameter of 10 mm on the surface of the (A type), and affixing the pressure-sensitive element to a measurement site on the human body surface It is done wearing.

The relationship between the clothing pressure and concentration and attention is one of the brain potentials involved in concentration, such as "C".
By measuring "NV", it can be qualitatively grasped. Here, “CNV” is one of the brain potentials called concomitant negative fluctuations.
It is believed that the negative values of "NV" have increased and reflect concentration, attention, and preparedness for motor responses.

In order to optimize the clothing pressure of tights worn during exercise in relation to the nervous system such as concentration,
The following experiment was performed. First, as an experiment 1, “CNV” was measured while changing the pressure level by wrapping a cuff around the lower leg of both feet of the subject. From the value of “CNV” when pressurized, “CNV” when not pressurized was measured. ”And subtract“ ΔC
NV ₁ ". As a result, as shown in FIG.
“ΔCNV ₁ ” is best when pressurized at 0 to 80 gf / cm ^2.
Was found to be high.

Next, in Experiment 2, a cuff was wrapped around the lower leg of both feet of the subject and pressurized at 72 gf / cm ^2.
Measuring the V ", it was by subtracting the value of the" CNV "when the thigh and lower leg is not pressed both pressurized and" ΔCNV ₂ ". As a result, as shown in FIG. 2, when the lower leg is pressurized at 72 gf / cm ² , the thigh becomes 15-30 gf / cm ^2.
It was found that “ΔCNV ₂ ” was the highest when pressure was applied.

From this measurement result, the clothing pressure on the thigh was reduced to 15
３０30 gf / cm ² , clothing pressure on lower leg 60-80 gf
/ Cm ² , it was found that “CNV” was the highest.

[0020] If the clothing pressure on the thigh is greater than this, "CN
“V” decreases, and if the clothing pressure on the lower leg is higher or lower than this, “CNV” decreases and the effect is not expected much. Furthermore, as can be seen from the experimental results, the difference in the clothing pressure between the thigh and the lower leg, which is such that the clothing pressure is continuously changed, is expressed as “C
The effect of increasing the “NV” cannot be obtained. Clothes pressure on the thigh can be obtained by using a two-way tricot cloth or the like with normal tension, but clothing pressure on the lower leg is necessary for cloths with normal tension only by reducing the pattern size. Cloth pressure cannot be obtained, and easiness of attachment and detachment is extremely poor. Therefore, it is necessary to use a fabric having both high tension and sufficient elasticity. Therefore, in order to obtain the clothing pressure difference between the thigh and the lower leg to the extent that the effect is obtained, it is necessary to extremely change the tension of the cloth at a certain position between the thigh and the lower leg.

Therefore, the fabric used for the lower leg is JIS
After stretching at a tensile speed of 200 mm / min to a load of 1.8 kg by the L1096 constant-speed extension method, and then returning at a constant speed to draw a stress-strain curve, the stress at the 30% elongation of the return was defined as the tension force. In this case, the weight is desirably 250 g or more and 1000 g or less. For the dough used for that,
A tricot or Russell knitted fabric using a polyurethane elastic yarn of 200 denier or more, and a cloth knitted with a synthetic fiber of 30 to 70 denier such as nylon or polyester, and the polyurethane elastic yarn is 280 denier or more. It is preferred to use two types of polyurethane elastic yarns, one of 40 to 70 denier. In addition, a stretchable fabric containing polyurethane elastic yarn, one side of which is coated with a stretchable resin film such as polyurethane or silicone, or coated with the resin, or a three-layer laminate of stretchable fabric. It can be appropriately selected from those having a structure.

If the pattern for sewing the long tights according to the present invention is designed so that both feet can be sewn with a single suture line at the rear, the pattern is formed along the bulge of the leg. It is preferable because uniform clothing pressure can be easily obtained in each of the lower part and the lower leg.

Next, a one-piece type garment used in skiing and skating competitions and a garment used in various competitions such as cycling competitions and rowing competitions, which are made of stretchable fabric and are closely attached to the body for sports Also in clothing, the clothing pressure on the thigh and lower leg, upper arm and lower arm, and abdomen and chest can be changed by means similar to the above-mentioned long tights.

[0024]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As one embodiment of the long tights according to the present invention, as shown in FIG.
In long tights in which both feet are sewn by a single suture line at the rear, the fabric is switched just below the knee joint, and the fabric constituting the thigh is made of 40 denier nylon thread and 40 denier polyurethane. The two-way tricot fabric made of elastic yarn was used, and the fabric constituting the lower leg portion was formed of a Russell knitted fabric in which 50 denier nylon yarn and two types of polyurethane elastic yarn of 280 denier and 70 denier were mixed and knitted. The clothing pressure in the example is 20 to 25 gf / cm ^{2 for} the thigh and 65 to 70 gf / cm for the lower leg.
cm ² . As the comparative product A, a product formed entirely of a two-way tricot fabric composed of 40 denier nylon yarn and 40 denier polyurethane elastic yarn was used.

The clothing pressure of the comparative product A was ²⁰ to 25 gf / cm ² for both the thigh and the lower leg. As the comparative product B, the clothing pressure of both the thigh and the lower leg was set considerably higher than that of the general product. The clothing pressure of the comparative product B is the thigh,
The lower thigh was 40 to 50 gf / cm ² . The invented product, the comparative product A, the comparative product B, and the non-wearing state were compared by measuring brain waves by the following method.

A pair of sound stimuli are given to the eight healthy male subjects at regular intervals in a sitting resting state, and a button is pressed for the second stimulus, and the CNV between the first stimulus and the second stimulus is pressed. (Concomitant negative fluctuation) was measured, a value obtained by integrating the CNV value between the first stimulus and the second stimulus was determined as CNV, and the difference from CNV ₀ when the tights were not worn was ΔCNV.
And FIG. 4 shows the results. From this experimental result, it was found that the product of the present invention has a larger negative value of ΔCNV than the comparative product A and the comparative product B, and the concentration and the attention are increased.

Next, the effects of the product of the present invention, the comparative product B, and the unworn condition on the circulatory system were measured by the following method and compared. After measuring the sitting rest on the bicycle ergometer for 5 minutes for 7 healthy male subjects, exercise was performed for 35 minutes so that the heart rate was 120 beats / minute as a load period. As a recovery period, sitting rest was maintained on a bicycle ergometer for 20 minutes after the end of exercise. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (D
BP), calculate the double product (DP),
The difference between exercise and rest was taken as ΔDP. here,
Double products include heart rate (HR) and systolic blood pressure (SB)
P) and is an index of the energy consumption of the heart, and indicates the magnitude of the burden on the heart.
The result is shown in FIG. From this experimental result, it was found that in the present example, the double product was reduced by about 20% as compared with the comparative product B and the non-wearing state, so that the burden on the heart was small and the fatigue during exercise was small.

[0028]

The effects of the sports clothing according to the present invention will be summarized. Explaining the long tights, when the user wears the long tights and exercises, a moderate feeling of tightening on the lower leg enhances concentration and attention and facilitates preparation for a reaction to the next operation. In addition, since the thigh and the lower leg have a boundary line immediately below the knee joint, the clothing pressure on the lower leg is higher than that of the thigh, so that the blood that tends to stay in the lower leg can be returned to the heart and helped. It has the effect of reducing fatigue and also reducing the burden on the heart. Therefore, agility and endurance are improved, and an improvement in competition results can be expected.

In the long tights according to the present invention, since the portions from the knee joints to the thighs, buttocks and waist are made of a fabric having a relatively low tension, unnecessary twitching during exercise can be prevented. It does not occur and does not interfere with motor function. As a result, warm-up can be performed efficiently, and a game can be played while wearing the long tights according to the present invention.

In addition, in the long tights according to the present invention, since the material constituting the lower leg is made of a material having a higher tension than the material constituting the thigh, the clothing tightness difference is reduced. It is not necessary that only the lower leg is narrowed down to obtain a shape. Therefore, tights that are not unsightly in appearance and are excellent in fashion can be obtained.

Next, one-piece type clothes used in skiing and skating competitions and clothes used in various competitions such as cycling competitions and rowing competitions, which are made of stretchable fabric and are closely attached to the body. Also in clothes, by changing the clothes pressures of the thighs and lower thighs, upper arms and lower arms, and abdomen and chest, it is possible to exert the same operational effects as the above-mentioned long tights.
