Description

  The present invention relates to exercise spats worn when exercising, and more particularly to exercise spats worn during running.

  Conventionally, sportswear such as sports spats has been studied to improve motor function by using appropriate materials. In recent years, sportswear has been proposed that applies taping theory in sports science to form parts that are difficult to stretch, prevent movement disorders such as bruises, bruises, and flesh, and improve motor function ( Patent Documents 1 to 3).

  On the other hand, in an exercise such as running where an impact is applied to the human body, when the input frequency due to the impact is close to the natural frequency of each part of the body, muscle activity to prevent resonance, that is, muscle tuning (Muscle activity reduced soft). -Issue resonance at heal-strike ducking walking. Waking JM et al, J. Biomech 36-12, 1761-1769, 2003) is considered to cause muscle fatigue and pain.

  However, in the sportswear described in Patent Documents 1 to 3, the portions that are difficult to expand and contract are arranged so as to produce the same effect as the taping effect along the joints and muscle fibers, and to suppress muscle tuning. Has not been considered at all.

  In order to solve the above-described conventional problems, the present invention provides an exercise spat that suppresses muscle tuning in the lower limbs and improves an exercise function.

  The exercise spats of the present invention are exercise spats that are stretchable and are worn in a state of being in close contact with the surface of the body, including the outer thigh, the proximal third of the front thigh, and the front thigh A power part is arranged in a region A including the proximal third of the inner part.

  In addition, the exercise spats of the present invention preferably include a rear thigh inner side distal 2/3, a rear thigh center distal 1/3 to a proximal 1/3 and a rear thigh outer side distal 1/3. A power part is also arranged in the region B.

  In the exercise spats of the present invention, preferably, a power part is also arranged in a region C including the proximal lower leg part 2/3.

  According to the present invention, in the exercise spats, by arranging the power part in the region A including the outer thigh portion, the proximal one third of the thigh front central portion, and the proximal third of the thigh front inner portion, In addition, the vibration associated with the movement of soft tissue (including muscle and fat) in the outer thigh area is reduced, and the muscle activity that is originally necessary for reducing the vibration, that is, muscle tuning, is suppressed. Can reduce the load and improve the motor function. In the exercise spats of the present invention, preferably, the rear thigh inner surface distal portion 2/3, the rear thigh central portion distal 1/3 to the proximal 1/3 and the rear thigh outer surface distal portion 1/3 By arranging the power part in the region B including the vibration, the vibration associated with the movement of the soft tissue in the back of the thigh is reduced, and the muscle activity inherent to the vibration reduction, that is, muscle tuning is suppressed, thereby suppressing the muscle of the thigh. Can reduce the extra load and improve motor function. In the exercise spats, preferably, the present invention reduces vibration associated with the movement of the soft tissue in the crus by disposing the power region in the region C including the crus outer side proximal 2/3, By suppressing the muscle activity that is originally necessary for reducing the vibration, that is, muscle tuning, it is possible to reduce an extra load on the muscles of the lower leg and improve the motor function.

  The inventors have found that, in the exercise spats, the power region is arranged in a region corresponding to a region where muscle tuning is likely to occur, thereby suppressing muscle tuning in the lower limbs and improving the motor function. It was.

  The region where muscle tuning is likely to occur was specified by obtaining the evaluation function Q at each part of the lower limb. Here, as shown in the following formula (1), the evaluation function Q is a coefficient k representing the closeness of the input frequency during running and the natural frequency of each part of the lower limbs determined by the Blackman window function, and the acceleration. This is indicated by the product of the peak value / input force (a / F) and the inertance of each part of the lower limb. The higher the evaluation function Q, the greater the inertia (easier to shake) and the more likely the part to resonate. Can be considered. In the present invention, the input force F is the maximum value of the force applied to the body when hit with an impulse hammer, and is, for example, the height of x shown in a thick graph in FIG. The acceleration peak value a is the peak value of the acceleration waveform that appears after the impact, and is, for example, the height a shown in the thin graph in FIG.

(Formula 1)
Q = k (a / F)

In order to obtain the evaluation function Q, first, the natural frequency at each part of the lower limb was obtained by a method using an impulse hammer. Specifically, the natural frequency was determined based on the acceleration waveform obtained when 24 thighs and 24 crus were hit with an impulse hammer. The measurement was carried out by attaching an accelerometer to each part of the lower limb, and further hitting a 3 cm distal part of the accelerometer with an impulse hammer. In addition, measurement was performed at each site until a stable waveform was obtained 5 times. FIG. 1 shows an example of an acceleration waveform (thin line) obtained when a thigh is hit using an impulse hammer. FIG. 1 also shows a force input waveform (thick line) by an impulse hammer. In FIG. 1, the time difference Δt between the first peak a and the second peak b of the acceleration waveform is obtained, and the reciprocal of Δt is taken as the natural frequency f _n . Table 1 below shows the natural frequencies f _n in the thigh and crus. In addition, although the natural frequency differs depending on the part of the thigh and crus, the natural frequency is low in the thigh with many soft tissues on the surface, and the tibia exists near the front surface in the crus. A part with a specifically high frequency was confirmed.

Next, the input frequency during running was obtained. In addition, the input frequency at the time of running changes with speed, how to run, a road surface state, shoes, etc. Therefore, the input during running is based on the vertical floor reaction force waveform obtained by wearing various shoes and measuring the floor reaction force during landing at a general running speed of 10 km / hour. The frequency was determined. FIG. 2 shows an example of a floor reaction force waveform in the vertical direction at the time of landing during running at a general running speed of 10 km / hour. In FIG. 2, according to “Muscle activity in the leg is tuned in response to impact force charactics” (Boyer and Nigg, J Biomech 37, 1583-1588, 2004), maximum load rate (Max) up to ground initial maximum load (Impact Peak) (d), regarded as 1/4 of the input waveform cycle, a time difference Δti both multiplied by four, and the input frequency f _i taking the reciprocal. As a result, in the running at 10 km / hour, the input frequency of the impact due to grounding was in the range of approximately 13 to 25 Hz. This difference was mainly due to the difference in shoes, and there was a tendency for shoes with a harder ground contact to be higher.

  Subsequently, an evaluation function Q depending on the natural frequency and inertance of each part of the lower limb was obtained. When the input frequency at the time of running and the natural frequency in each part of the lower limb are approximate values, muscle contraction to prevent resonance can occur (Muscle Tuning), but at this time, the inertia in the vibration of each part of the lower limb is large. That is, it is considered that more muscle activity is necessary for a portion that is more likely to vibrate to suppress the vibration. Therefore, as shown in FIG. 3, a coefficient k representing the proximity of the input frequency during running and the natural frequency of each part of the lower limb is obtained by the Blackman window function, and the acceleration peak value / input force (a / The product of the inertance shown in F) was used as the evaluation function Q. The higher the value of the evaluation function Q, the greater the inertia (easier to shake) and the more likely it is to resonate. The evaluation function Q obtained for each part is divided into a thigh and a lower leg and visualized by a visualization software “MicroAVS” (manufactured by K.G. T., Ltd.), and the visualized image is “3DCG software Maya”. The visualization result of the evaluation function Q obtained by texture mapping on the CG of the lower half of the body (manufactured by Autodesk) is shown in FIG. In FIG. 4, the degree 10 indicates the magnitude of the evaluation function Q, and indicates that the value of the evaluation function Q is higher in the direction from I to II. From FIG. 4, it can be seen that the value of the evaluation function Q of the outer thigh portion 12, the thigh inner portions 13 to 15, the rear thigh center 16 and the lower thigh outer portion 17 is high, and muscle tuning is likely to occur. Therefore, the present invention suppresses muscle tuning in the lower limbs by locating power parts in areas where muscle tuning is likely to occur, such as the outer thigh, inner thigh, rear thigh center, and outer thigh. Provide improved athletic spats.

  In the present invention, “having stretchability” means that the stretch rate of the fabric constituting the exercise spats exceeds 0% in the width direction (the minor axis direction of the body). In addition, the elongation rate in the length direction (body long axis direction) of the fabric constituting the exercise spats of the present invention is not particularly limited, and may be 0%, may exceed 0%, and the average elongation rate is 60 to 60%. It is preferably 170%. In the present specification, unless otherwise indicated, the elongation rate means the elongation rate in the width direction of the fabric (the minor axis direction of the body). In the present invention, the elongation rate specifically refers to the length of the fabric piece in an unloaded state measured according to JIS L 1096 using a fabric piece having a width of 5 cm and a length of 30 cm. When A is set to B and the length of the dough piece in a state where a load of 20 N is applied in the width direction (the minor axis direction of the body) is set to B, this is indicated by [(BA) / A] × 100.

  In the present invention, in order to create a “substantially close contact” state, the peripheral direction is 50 to 110%, more preferably 70 to 95%, and the length is 75 to 100% relative to the naked size of the human body. Preferably, exercise spats are formed as 85 to 100%. Of course, since the size of the human body varies among individuals, the above ratio is a guide. More specifically, the size is determined according to the JASPO standard.

  The exercise spats may be formed so as to cover up to the knee, below the knee, or to the ankle. If the above exercise spats are formed so as to cover the knee, by placing the power part on the thigh, the muscle tuning of the thigh is suppressed, muscle fatigue and pain are alleviated, The motor function can be improved. In addition, when the above exercise spats cover below the knee, especially the ankle, a power region can also be placed on the lower leg, and muscle tuning of the lower leg can be suppressed in addition to the thigh. Can relieve muscle fatigue and pain and further improve the motor function of the entire lower limbs.

  From the viewpoint of suppressing the muscle tuning of the entire lower limb and further improving the motor function of the entire lower limb, it is preferable that the exercise spats have power portions arranged in all of the regions A, B, and C.

  Moreover, in this invention, it is preferable that the average elongation rate of the cloth which comprises the spats for exercise is 70% or more for a feeling of wear, and it is more preferable that it is 70 to 90%. In the present invention, the average elongation rate means the average of the elongation rates of the fabrics having different elongation rates constituting the athletic spats, as measured above.

  Although the said power site | part is not specifically limited, It is preferable that it is comprised with the fabric whose elongation rate in the width direction is 20 to 80%, and it is comprised with the fabric whose elongation rate in the width direction is 30 to 80%. More preferably, it is particularly preferable that the stretch rate is 30 to 70%. When the stretch rate in the width direction is 20 to 80%, the wearing feeling is also good, and muscle tuning is easily suppressed. In the present invention, when the power portion is formed by double punching, it is preferable that the backing fabric is composed of a fabric having a stretch rate in the width direction of 20 to 80%, and the stretch rate in the width direction is It is more preferably composed of 30 to 80% fabric, and particularly preferably composed of a fabric having an elongation rate in the width direction of 30 to 70%. When the stretch rate in the width direction is 20 to 80%, the wearing feeling is also good, and muscle tuning is easily suppressed. In the present invention, when the power part is formed by double punching, the “fabric constituting the power part” means the cloth to be lined.

  In the exercise spats, although not particularly limited, the elongation rate of the fabric constituting the power region is based on the elongation rate of the fabric constituting the region excluding the power region (hereinafter referred to as a high stretch portion). 10 to 70% lower, more preferably 20 to 70% lower, and particularly preferably 40 to 70% lower. When the stretch rate of the fabric constituting the power part is 10% or more lower than the stretch rate of the fabric constituting the high stretch part, the power feeling by the power part is good, and a sense of support for muscles is easily obtained, Muscle tuning can be suppressed. On the other hand, if the difference between the stretch rate of the fabric constituting the power part and the stretch rate of the fabric constituting the high stretch portion is less than 70%, appearance defects due to seam puckering or the like are unlikely to occur, and stress is applied locally. Does not feel uncomfortable between the fabric of the power part and the fabric of the high stretch part during use, and is less likely to break.

  Although the said high stretch part is not specifically limited, It is preferable that it is comprised with the fabric whose elongation rate in the width direction is 55-170%, and it is comprised with the fabric whose elongation rate in the width direction is 65-155%. Is more preferable, and it is more preferable that the stretch ratio in the width direction is made of a cloth having 75 to 115%. A feeling of wear becomes more favorable that the elongation rate in the width direction is 75 to 115%.

In the present invention, clothing pressure by the power portion is preferably 9~25g / cm ^2, more preferably 10~22g / cm ^2. If the clothing pressure by the power region is 9 to 25 g / cm ² , the amount of muscle activity during exercise such as running can be reduced, and the wearing feeling is also good. In the present invention, clothing pressure refers to a measurement made as follows, with exercise spats worn on a mannequin of the same size. Specifically, after fixing the clothing pressure sensor to the measurement site, the user wears exercise spats and repeats attachment and detachment at least three times to measure the clothing pressure. The clothing pressure shows a peak value immediately after wearing and then gradually decreases for stress relaxation, but the measured value is the peak value immediately after wearing.

The fabric of the power part and the fabric of the high stretch portion are not particularly limited as long as they have stretchability, and normal spats fabrics such as woven fabrics and knitted fabrics can be employed. As the woven fabric, for example, plain weave, oblique weave, satin weave, altered plain weave, altered satin weave, altered satin weave, alter weave, crest weave, one-ply weave, double structure, multiple structure, warp pile weave, weft pile weave, There are tangles. Examples of the knitted fabric include round knitting, weft knitting, warp knitting (including tricot knitting and raschel knitting), pile knitting, etc., flat knitting, tengu knitting, rib knitting, smooth knitting (double-sided knitting), rubber knitting, pearl knitting , Denby tissue, cord tissue, atlas tissue, chain tissue, insertion tissue, etc. The dough preferably has a basis weight in the range of 120 to 280 g / m ² , more preferably in the range of 140 to 250 g / m ² , and particularly preferably in the range of 160 to 230 g / m ² . If it is said range, there exists an advantage which does not impair a motor function, is durable, is light and is easy to move. The cloth may be impregnated or pressed with an elastomer resin or rubber. Elastomer resins include urethane elastomers, soft vinyl chloride elastomers, styrene elastomers, olefin elastomers, ester elastomers, amide elastomers, chlorinated polyethylene elastomers, Syn-1,2-polybutadiene elastomers, Trans-1 , 4-polyisoprene elastomer, fluorine elastomer and the like. Examples of rubber include silicone rubber, fluorine rubber, urethane rubber, synthetic rubber, and natural rubber. Moreover, the said cloth | dough may be one sheet and what laminated | stacked the two sheet | seats of a different expansion | extension rate may be sufficient.

  The fibers constituting the fabric are not particularly limited. For example, polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyurethane fibers, polyamide fibers, acetate fibers, cotton fibers, rayon fibers, ethylene vinyl alcohol Fiber, nylon fiber, etc. can be used.

  This will be described below with reference to the drawings. 5A is a front view of an exercise spat in one embodiment of the present invention, FIG. 5B is an inner side view thereof, FIG. 5C is a rear view thereof, and FIG. 5D is an outer side view thereof. The spats 20 for exercise include a region A including a thigh outer side portion (A1), a proximal one-third (A2) of the front surface of the thigh and a proximal third portion (A3) of the inner front portion of the thigh, and a rear thigh inner surface portion Position B / 3 (B1), region B including posterior thigh central portion distal 1/3 to proximal 1/3 (B2) and posterior thigh outer side distal 1/3 (B3), crus outer side proximal 2 / 3 (C1) is included in the region C including the region C1.

It is like that.

  The athletic spats may constitute a power part and a high stretch portion using fabrics having different elongation rates, respectively, and after creating the spats with one type of fabric having a predetermined elongation rate, the regions A and the regions B. The power region may be formed by lining the region C with a cloth having a predetermined elongation rate and an elongation rate different from each other. Also, using a special fabric made by aligning nylon and polyester, such as “Seiren Bisco Magic” (manufactured by Seiren Co., Ltd.), the power part can be formed by dissolving only polyester with a special solvent at a predetermined position. Good. Moreover, you may produce by knitting a power site | part and a high stretch part with a different fiber composition using the machine for exclusive use of the "hole garment" of Shima Seiki Seisakusho. Above all, from the viewpoint that the feeling of wearing becomes better, the above-mentioned sports spats use special fabrics such as “Seren Bisco Magic” (manufactured by Seiren Co., Ltd.) or “Hall Garment” dedicated machine of Shima Seiki Seisakusho, The width direction (the minor axis direction of the body) is preferably formed seamlessly.

In the M size mannequin, as shown in FIG. 5, clothing pressure sensors are fixed to the lower leg outer side 24, lower leg rear part 23, thigh outer side 21, and thigh rear part 22, and the exercise spats of the M size Example 4 or Comparative Example 1 Wearing was used to measure the clothing pressure. The clothing pressure showed a peak value immediately after wearing and then gradually decreased for stress relaxation, but the measured value was the peak value immediately after wearing. For the clothing pressure data, the mean ± SD was calculated from the mean value and standard deviation (SD) at each part. Further, from the average value and standard deviation (SD) at each site, an average ± 2SD (a range including approximately 95.44% assuming that the population is normally distributed) was calculated.

(Muscle activity)
Each subject was allowed to wear running pants and the exercise spats of Example 4 and Comparative Example 1 at random, and the amount of muscle activity was measured as follows under each condition. Specifically, the subject is allowed to run at a running speed of 10 km / hour on a treadmill, and as shown in FIG. 5, the anterior tibial muscle on the outer side of the lower leg 24, the lateral head of the gastrocnemius at the rear part 23 of the lower leg, and the outer vastus muscles on the outer side of the thigh 21. The EMG (electromyogram) of hamstrings in the back thigh 22 was derived and the amount of muscle activity was evaluated. More specifically, the obtained electromyogram waveform is subjected to full-wave rectification, and the average amplitude in the section from 0.1 second before contact to 0.2 second after contact is obtained for each step, and the average value for all steps Asked. Further, for comparison, a relative value with the amount of muscle activity at the time of wearing the running pants taken as 100 was obtained for each muscle of each subject under each condition and used as an index of muscle activity. There were 5 test subjects, and Table 2 below shows average values.

  As can be seen from the results of Table 2 above, when wearing the exercise spats of Example 4 in which the power parts are arranged in the regions A, B and C, the exercise spats of Comparative Example 1 in which the power parts are not arranged The amount of muscle activity during running was reduced as compared to the case of wearing the. This tendency was conspicuous in the anterior tibial muscle, lateral vastus muscle, and hamstring, which are muscles located in the region where the power site is disposed. This is presumed to be due to the fact that the muscle tuning was suppressed because the power part was arranged in the part where muscle tuning is likely to occur in the exercise spats of the example.

(Wear test results)
The exercise spats of the examples and comparative examples were worn, and a wear test was performed as follows. The results are shown in Table 3 below.

<A feeling of wearing>
After wearing the exercise spats, the feeling of wearing was evaluated by the following three-step sensory evaluation. There were 5 test subjects, and Table 3 below shows average values.
1 A little tight 2 Good 3 A little loose

<Power difference>
After wearing athletic spats, the difference in power was evaluated by the following four sensory evaluations. There were 5 test subjects, and Table 3 below shows average values.
1 No 2 Slightly weak 3 Good 4 Strong

  As can be seen from the data of the examples in Table 3, the exercise spats of Examples 1 to 12 in which the power parts are arranged in the area A, the area B, and the area C are not bad in wearing feeling. There is also a sense of power difference. Moreover, it turns out that a feeling of wear is favorable when the average elongation rate of the cloth in the exercise spats is 70 to 90%. Moreover, when the stretch rate difference between the fabric of the power part and the stretch rate of the fabric of the high stretch portion is 10 to 70%, the sense of power difference is good, a sense of support for the muscle is obtained, and muscle tuning is easily suppressed. . On the other hand, in Comparative Example 1 which is made of a fabric having no power portion and having a constant elongation rate, there is no sense of power difference, a sense of support for muscles cannot be obtained, and muscle tuning cannot be suppressed.
