Description

  By wearing, the bottom which can activate the contraction activity of a muscle and can increase calorie consumption is provided.

  Obesity due to poor dietary balance or reduced exercise is called obesity or metabolic syndrome, and is regarded as a problem because it causes serious illness such as diabetes and arteriosclerosis. Conventionally, in order to eliminate such obesity, sweating is promoted by wearing a sauna suit or sweating supporter, slimming supplements, etc., or aerobic exercise such as light jogging, walking, cycling etc. Or trying to increase calorie consumption.

Moreover, as innerwear having a diet effect when worn, a heel protruding inward from the inner surface of the innerwear is formed, and a linear ridge extending in the course direction of the knitted fabric is in contact with the linear heel and The part corresponding to the thigh and the abdomen near the base of the foot when wearing a composite heel region in which a large number of composite heels combined with two wavy heels facing each other across a straight heel are formed An inner wear is provided in which the composite heel region massages the wearer's abdomen and the like and tightens the body due to blood circulation promoting effects (Patent Document 1). Moreover, the innerwear which formed the inclined convex part alternately for the same objective is also proposed (patent document 2).
JP 2004-204411 A Patent No. 4047748

  However, the amount of calories consumed by exercise when wearing a sauna suit or sweating supporter is not much different from that when exercising without wearing a sauna suit or the like. Because it only has the effect of reducing the weight, it cannot be expected to have a great effect in eliminating obesity. Also, when taking slimming supplements, etc., there is a risk of side effects, so use with caution.

  Although aerobic exercises such as light jogging, walking and cycling are said to be suitable for calorie consumption, the muscles that are contracting during aerobic exercise are actually part of the muscle belly. There is no active contraction activity at both ends of the muscle near the tendon, and no efficient calorie consumption is performed because the entire muscle from the stop to the start is not contracted (Fig. (See 5 (a).)

  Furthermore, in the innerwear described in the above-mentioned Patent Document 1, the composite heel projecting inward from the inner surface of the innerwear exhibits a massage effect during exercise of the wearer, etc., and promotes blood circulation around the abdomen. However, since the muscles that are active during exercise remain in a part of the muscle abdomen, the calorie consumption is not efficiently performed as compared with the case where the whole muscles perform contraction activity.

  In general, the contraction activity during exercise is mainly a part of the muscle abdomen, and the contraction activity is hardly performed at both ends of the muscle near the tendon. Therefore, the calorie consumption due to exercise or the like is limited to the amount consumed by the contraction activity of a part of the muscle belly. However, even if the same exercise is performed, if the entire muscle is contracted, more calories are consumed than the contraction activity of a part of the muscle belly, so more calories are consumed. There is no doubt. Therefore, if the contraction activity by the whole from the stop part of the muscle to the start part can be activated, calories can be consumed more efficiently even with the same exercise operation and time. In particular, since the abdomen, buttocks and thighs are difficult to perform muscle contraction activity, it is necessary to promote activation of contraction activity with an external force.

  Therefore, the present invention activates the contraction activity by the entire muscle from each stop to the start of each of the rectus abdominis, gluteal muscles, biceps femoris and quadriceps by wearing, It is an object to provide a bottom intended to increase.

  In order to solve the above problems, the present invention is configured as follows. That is, the bottom according to the first aspect of the present invention includes a waist opening, a crotch part, and left and right leg openings, and a bottom region that is in close contact with the wearer's skin, The lateral pressure line and the vertical pressure line, which are less stretchable than the main body region, intersect the areas corresponding to the rectus abdominis muscle, the buttocks muscle group, the biceps femoris muscle, and the quadriceps femoris muscle. A plurality of knitted grid-like pressure regions are formed, so that the lateral pressure lines divide contraction activities of the muscles to form pseudo tendons, and It is characterized by the fact that the direction of the pressure line suppresses contact blurring to the skin, thereby activating muscle contraction activity.

  Moreover, the bottom according to claim 2 according to the present invention is the bottom according to claim 1, wherein the lateral pressure line is worn on a body region including a portion corresponding to each muscle, A plurality of pressure lines formed in a horizontal ring shape are knitted with a predetermined knitting width and interval, and the vertical pressure lines are knitted in a body region from the waist opening to the left and right leg openings. In addition, the horizontal lines are knitted so as to intersect the horizontal pressure lines between the horizontal pressure lines.

  If the bottom according to the present invention is worn, the lateral pressurization line in the pressurized region knitted to be difficult to stretch pressurizes the muscle on the pressurization line by the applied pressure, thereby dividing the muscle contraction activity. By forming a tendon in a pseudo manner, the pressure line in the vertical direction is in close contact with the skin, and blurring of the pressure line in the horizontal direction during exercise is suppressed, thereby reducing the size in the pseudo tendon. Since the contracted muscle contraction activity is surely performed at both ends of the muscle in the vicinity of the tendon, the contraction activity by the entire muscle from the stop portion to the start portion is activated and the calorie consumption can be increased. Further, by forming the lateral pressure line in a lateral ring shape when worn, it is possible to maintain the strengthening and stability of the pressure applied to each muscle.

  The best mode for carrying out the present invention will be specifically described below with reference to the drawings. Here, the bottom refers to clothing such as pants, spats, shorts, girdle, tights, or stockings that covers the abdomen, buttocks, and thighs when worn. Hereinafter, a description will be given using shorts.

  FIG. 1 is a front view of a bottom 1 according to the present invention, and FIG. 2 is a rear view of the bottom 1. In the bottom 1, the main body region 2 intersects with a hardly stretchable horizontal pressure line 3 (hereinafter referred to as a horizontal line 3) and a vertical pressure line 4 (hereinafter referred to as a vertical line 4). The pressure region 5 is formed in a lattice shape. When the bottom 1 is worn, the pressurizing region 5 includes an abdominal part (stratus abdominal muscle), buttocks (group of gluteal muscles including major ankle, middle ankle, and small ankle) and thigh (biceps femoris, It is knitted to cover the quadriceps.

  The pressurizing region 5 on the front side shown in FIG. 1 is knitted at portions corresponding to the rectus abdominis and quadriceps muscles. The horizontal line 3 of the front pressure region 5 is knitted with a width of 0.5 cm to 5.0 cm, and the left and right ends of the front knitting are connected to the body region 2 from the waist opening 6 to the crotch portion 7. Three horizontal lines to be tied are knitted at intervals of 3.0 cm to 8.0 cm, and the body region 2 from the crotch portion 7 to the leg opening portion 8 is lateral to each of the portions corresponding to the left and right thighs. Five directional lines are knitted at intervals of 3.0 cm to 8.0 cm. The waist opening 6, the crotch part 7 and the leg opening part 8 have the same stretchability as that of ordinary shorts using elastic yarn, and the crotch part 7 uses a mesh material with good air permeability. May be.

  In addition, the vertical line 4 is knitted with a width of 0.3 cm to 3.0 cm, and in the main body region 2 from the waist opening 6 to the crotch 7, in the knitting area from the waist opening 6 to the uppermost horizontal line 3, A total of 10 lines, one each on the left and right ends of the front side knitting, and four on each side of the central axis α (stitch), are knitted in the vertical direction at intervals of 1.5 cm to 8.0 cm. Each time the lower horizontal line 3 is knitted, it is knitted symmetrically with respect to the central axis α while gradually decreasing the outer vertical lines 4 one by one except for the vertical lines 4 at both left and right ends. Further, in the body region 2 from the crotch portion 7 to the leg opening portion 8, from the uppermost horizontal line 3 of the part corresponding to the left and right thighs to the next horizontal line 3 with the knitting width and interval of the vertical line 4. In the knitting area, two vertical lines are knitted on the left and right sides near the central axis α, and each time the lower horizontal line 3 is knitted, the vertical lines 4 are knitted in the same number or outside. While being gradually increased, the knitting is performed symmetrically with respect to the central axis α.

  Thus, in the front side knitting, the pressurizing region 5 formed by intersecting the horizontal line 3 and the vertical line 4 is knitted at a site covering the rectus abdominis and quadriceps muscles when worn. The reason why the pressurization region 5 is not provided in the knitting region corresponding to the lower part of the abdomen is that excessive pressurization to the inguinal region may inhibit venous return of the lower limbs.

  Further, the pressurization region 5 on the back side shown in FIG. 2 is knitted at sites corresponding to the upper major gluteal muscle, the middle gluteal muscle, the small gluteal muscle, and the biceps femoris. The horizontal line 3 of the pressure area 5 on the back side is formed in the main body area 2 from the waist opening 6 to the crotch part 7 with the knitting width and interval of the horizontal line 3 and the three horizontal lines 3 on the front side. A horizontal line connecting the left and right ends of the back side knitting is knitted at the portion corresponding to the knitting, and a horizontal line having a length of 1.0 cm to 4.0 cm is knitted from the left and right ends only for the lowermost horizontal line 3. . Further, in the main body region 2 from the crotch portion 7 to the leg opening portion 8, five horizontal lines are knitted in each of the left and right knitting, corresponding to the knitting position of the horizontal line 3 on the front side. These lateral lines 3 on the back side are knitted by being connected to the corresponding lateral lines 3 on the front side, and when the bottom 1 is worn, the lateral lines 3 are formed in a ring shape.

  Further, the vertical line 4 is centered in the knitting area from the waist opening 6 to the uppermost horizontal line 3 in the main body region 2 from the waist opening 6 to the crotch 7 with the knitting width and interval of the vertical line 4. A total of 8 lines, 4 each on the left and right of the axis α (stitch), are knitted in the vertical direction, and the knitting area from the uppermost horizontal line 3 to the lower horizontal line 3 has a central axis α. A total of 6 lines, 3 each on the left and right, are knitted in the vertical direction, and further, the inner end of the lowermost horizontal line 3 knitted with a length of 1.0 cm to 4.0 cm on the left and right ends and the upper side thereof Longitudinal lines 4 that vertically connect the lateral lines 3 are knitted and are symmetric with respect to the central axis α. Further, in the body region 2 from the crotch portion 7 to the leg opening portion 8, four vertical lines are provided for each knitting area sandwiched between the horizontal lines 3 with the knitting width and interval of the vertical lines 4. It is knitted symmetrically with respect to the central axis α so as to intersect the horizontal line 3. A vertical line 4 is also formed on the central axis α from the waist opening 6 to the crotch portion 7. Depending on the shape of the buttocks of the person who wears the bottom 1, for example, when a person with a relatively large buttocks wears the bottom 1, the knitted from the crotch part 7 to the left and right leg opening parts 8. The pressure region 5 may pressurize the lower part of the greater gluteal muscle.

  The knitting interval of the horizontal line 3 and the vertical line 4 may be changed depending on the wearer's body shape and sex, or may be changed depending on the size and shape of the muscle. For example, the knitting interval of the horizontal line 3 may be increased for relatively large muscles such as quadriceps and biceps, but each of the multiple abdominal muscles such as rectus abdominis. It is necessary to make the interval small in order to activate the muscle contraction activity for each belly.

  Here, the knitting material and the knitting structure of the main body region 2 and the pressure region 5 will be described. The main body region 2 is a plain knitting (flat knitting) made of a covering yarn having a high elongation and low stress polyurethane elastic yarn as a core yarn, and is knitted so that its pressure is 0 hpa to 30 hpa. Other than the above, and using a high-elongation low-stress polyurethane elastic yarn as the core yarn, it maintains a comfortable overall pressure-bonding that is in close contact with the body when the bottom 1 is worn, and a nylon yarn as a covering yarn for covering Etc. to ensure ease of wearing and good touch.

  Next, the horizontal line 3 in the pressurizing region 5 is knitted by alternately inserting a covering yarn and a nylon yarn, each having a polyurethane elastic yarn as a core yarn, based on the main body region 2 for each course. The polyurethane elastic yarn insertion course is knitted with a single knit miss (welt knitting), and the nylon yarn insertion course is knitted with a plain knitting, so that the pressure of the horizontal line 3 is 10 hpa to 50 hpa. It is organized to become. FIG. 3 is a diagram specifically showing the knitting structure of the horizontal line 3, and plain knitting is indicated by ◯ and knit mistakes are indicated by X. First, the first course is knitted using polyurethane elastic yarns, with one knitting miss for each well, and then the second course is knitted by plain knitting using nylon yarn. In the third and subsequent courses, the knitting of the first course and the second course is alternately repeated, and the number of knitting courses is adjusted according to the width 0.5 cm to 5.0 cm of the horizontal line 3. Due to the knit mistake of the polyurethane elastic yarn, the stretchability of the lateral line 3 in the lateral direction is suppressed to obtain a pressure higher than that of the main body region 2, and the nylon 1 is inserted every course, so that the bottom 1 is easy to wear. And to ensure good touch. Note that the covering yarn used for the knitting course in which the knit mistake is provided is not limited to the polyurethane elastic yarn as long as the desired pressure can be obtained, and the elasticity of the elastic yarn used as the core yarn is not limited. Depending on the condition, or in order to adjust the pressure, knitting mistakes may be knitted to increase appropriately.

  Next, the vertical line 4 uses a covering yarn having a high elongation and low stress polyurethane elastic yarn as a core yarn, and a knit mistake is provided for each knitting course based on the interval described in FIG. Knit so that the pressure is 5 hpa to 40 hpa. For the covering yarn, a nylon yarn having a good touch is used. FIG. 4 is a diagram for specifically explaining the knitting structure of the vertical line 4, and plain knitting is indicated by ◯ and knit mistakes are indicated by X. First, in the first course, a knit mistake for skipping two stitches is first provided, then two plain stitches are knitted, and then a knit mistake for skipping two stitches and a plain stitch are repeatedly knitted. From the second course to the eighth course, knitting is performed in the same manner as the first course, and the knit mistakes of skipping two stitches are continued in the vertical direction. Next, in the 9th course, first, two plain knittings are knitted, then a knit mistake for skipping two knittings is provided, and then, a plain knitting and a knit mistake for skipping two knittings are repeated for knitting. The 10th to 16th courses are knitted in the same way as the 9th course, and the knit mistakes of double stitching are continued in the vertical direction.

  As described above, the vertical line 4 is knitted while changing the knitting position where the knitting mistake of double knitting is skipped and the knitting position where two plain knittings are knitted every 8 courses. Repeat the same organization as the first course. Thus, by continuously knitting in the vertical direction while changing the knitting position of the knit mistake, the stretchability of the vertical line 4 is suppressed, and when the bottom 1 is worn, the vertical pressure is applied to the knitting of the vertical line 4. Obtainable. In addition, by using nylon yarn or the like as the covering yarn for covering, the ease of wearing and the good touch are ensured. Note that each of the covering yarns described above may be either a single covering yarn or a double covering yarn depending on the material of the elastic yarn used as the core material. The knitting of the vertical line 4 is not limited to polyurethane elastic yarns as long as the desired pressure can be obtained. Also, depending on the stretchability of the elastic yarn as the core yarn, or the pressure adjustment Therefore, knitting may be performed by appropriately increasing or decreasing the number of knitting misses.

  Each of the above-mentioned regions is knitted with a pressure of 0 hpa to 30 hpa for the main body region 2 and 10 hpa to 50 hpa for the horizontal line 3 in the pressurizing region 5 and 5 to 40 hpa for the vertical line 4. Within the range of pressure values, the knitting is always performed with the contact pressure such that the horizontal line 3 ≧ the vertical line 4> the main body region 2. The wearing pressure is measured by using an air pack type clothing pressure transducer AMI3037 manufactured by AIM Corporation and wearing it on a human body with a standard size bottom 1 that is always worn.

  FIG. 5 is a diagram showing muscle contraction when the bottom 1 is worn, in which FIG. 5 (a) shows muscle contraction of the quadriceps 9 when not worn, and FIG. The muscle contraction activity of quadriceps femoris 9 when 1 is worn is shown. Here, the quadriceps muscles 9 will be described as an example, but the bottom 1 also applies to other muscles such as the rectus abdominis muscle, the upper major ankle, the middle ankle, the small ankle, etc. corresponding to the knitting of the pressure region 5. If you wear, the same muscle contraction activity is performed. The quadriceps muscle 9 when not worn is hardly contracted in the upper and lower ends in the vicinity of the tendon, and is mainly performed in a part of the muscle abdomen in the vicinity of the center. The state of muscle contraction activity is indicated by arrows in the figure. When the bottom 1 knitted as described above is worn, the bottom 1 is brought into close contact with the wearer by the overall pressure of the main body region 2, and the horizontal line 3 of the lattice-shaped pressurization region 5 is applied by the pressure of the main body region 2 or more. The quadriceps muscles 9 are pressurized on the line to form pseudo tendon drawings to divide the muscle contraction activity, and shortened muscle contraction activities are performed in each tendon image.

  That is, the contraction activity that has been performed only in a part of the muscle abdomen of the quadriceps femoris 9 is shortened in each tendon by forming a pseudo tendon in the muscle and subdividing it. Since the contraction activity is performed, the muscle contraction activity is also performed at both ends of the muscle in the vicinity of the tendon. As a result, the contraction activity is activated in the quadriceps muscle 9 as a whole. Although not shown in FIG. 5, the vertical line 4 is attached to the skin and suppresses blurring during the movement of the horizontal line 3, thereby adding a corresponding part to ensure active muscle contraction activity. Press. As described above, muscle contraction activity is activated, calorie consumption can be increased, and obesity can be efficiently eliminated.

  Next, an experiment example is shown as follows about the calorie consumption at the time of exercising wearing the bottom 1. In the experiment, three females in their twenties were walking for 20 minutes on a treadmill (walking equipment) at a speed of 5.3 km / h in an environmental laboratory with a room temperature of 25 ° C. and a humidity of 50% RH. The calorie consumption was measured separately when not worn, when the bottom 1 was worn, and when the conventional product was worn.

  FIG. 6 shows a table and a bar graph showing the individual calorie consumption of three people. As shown in the table for each individual, the amount of calories consumed during walking for 20 minutes by subject A was 62.63 kcal when not wearing, 68.16 kcal when wearing bottom 1, and wearing a conventional product In some cases, it was 64.44 kcal. The amount of calories consumed when wearing the bottom 1 has increased by 8.8% compared to the amount of calories consumed when not wearing the bottom 1, and an increase rate of 2.9% when wearing the conventional product ( The amount of calories consumed is about 3.0 times that of the case of not wearing. The amount of calories consumed during walking for 20 minutes by subject B is 61.53 kcal when not wearing, 63.19 kcal when wearing bottom 1, and 62.00 kcal when wearing conventional products. The amount of calories consumed when wearing the bottom 1 is increased by 2.7% compared to the amount of calories consumed when not wearing it, and the rate of increase when wearing the conventional product is 0.8. The amount of calories consumed is about 3.4 times that of% (compared to the case of not wearing). The amount of calories consumed during walking for 20 minutes by the subject C is 63.34 kcal when not worn, 67.85 kcal when the bottom 1 is worn, and 66.04 kcal when the conventional product is worn. The amount of calories consumed when the bottom 1 is worn is increased by 7.1% compared to the amount of calories consumed when the bottom 1 is not worn, and the increase rate when the conventional product is worn is 4. The calorie consumption is increased by about 1.7 times compared to 3% (compared to the case without wearing).

  FIG. 7 shows the average calorie consumption of the three people in a table and a bar graph. The average calorie consumption 66.40 kcal when the bottom 1 is worn is 62.50 kcal when the calorie is not worn. The amount of calories burned is about 2.3 times that of the conventional product with an average calorie consumption increase rate of 2.7% (compared to the case of not wearing). Although the calorie consumption differs depending on the weight of the subject, the calorie consumption of each subject was remarkably increased as compared with the case of not wearing or wearing the conventional product.

  As a result of the above experiment, when the bottom 1 is worn as compared with the case where it is not worn and the case where the conventional product is worn, the calorie consumption is increased even with the same exercise operation and time, and the calorie is efficiently consumed. It is recognized that it is consumed. The bottom 1 used in this experiment reproduces the configuration shown in FIGS. 1 to 4, and the pressure of the main body region 2 is 13 hpa, the pressure of the horizontal line 3 is 23 hpa, the knitting width is 1.0 cm, and the knitting width is 1.0 cm. The spacing is 3.5 cm for the knitting area from the waist opening 6 to the crotch part 7, 4.5 cm for the knitting area from the crotch part 7 to the left and right leg openings 8, and the pressure applied to the vertical line 4 is 14 hpa, The knitting width is 0.5 cm and the knitting interval is 2.0 cm.

  In the above embodiment, the horizontal line 3 is knitted so as to have a ring shape when worn. However, the horizontal line 3 has a ring shape at portions corresponding to the rectus abdominis muscle, the buttocks muscle group, the biceps femoris, and the quadriceps. Instead, the grid-like pressurizing region 5 composed of the horizontal line 3 and the vertical line 4 may be knitted as one segmented region. However, as in the above-described embodiment, it is possible to maintain the strengthening and stability of the pressurization more by knitting the horizontal line 3 so as to have a ring shape when worn.

  The number of knitting of the horizontal lines 3 and the vertical lines 4 configured in the above embodiment is not limited to that shown in the above embodiment, and may be changed according to the wearer's body shape, age, sex, and the like. Moreover, in the display of FIG.1 and FIG.2, the reason why the horizontal line 3 and the vertical line 4 were not knitted in the vicinity of the crotch part 7 and the lower part of the hip part is that tightening to the hip part may be a burden at the time of wearing. If the wearer is thin, or the knitting of the body region 2 corresponding to the buttock is allowed to have a margin for a person whose buttock is large, etc. Line 3 and vertical line 4 may be provided. In addition, the pressure region 5 corresponding to the rectus abdominis muscle, the buttocks muscle group (major gluteal muscle, middle gluteal muscle, small gluteal muscle), the biceps femoris muscle, and the quadriceps femoris muscle is any one of the muscles. It may be knitted corresponding to any one of these muscles, or may be knitted corresponding to any combination of these muscles.

  In addition to the above embodiment, anything that is in close contact with the lower body, such as a swimsuit, can be obtained by forming a pressure tendon region 5 to create a pseudo tendon image, and shortening muscle contraction activity can cause muscles in the vicinity of the tendon. Since it is performed reliably at both ends, the contraction activity by the whole muscle from the stop portion to the start portion is activated and the calorie consumption can be increased.
