Description

Technical Field

[0001] The present invention relates to clothing incorporating blood flow restriction technology.

Background Art

[0002] Blood Flow Restriction (BFR) training, also known as vascular occlusion training, is an exercise method devised to rapidly increase muscle mass. It compresses the main blood vessel (or multiple main blood vessels) close to the muscle being moved, reducing the blood flowing through the main vein. This inhibits venous return in the muscle, causes venous pooling, and brings about metabolic stress. This can subsequently lead to rapid muscle growth, i.e., a greater increase in muscle tissue more quickly compared to the same muscle stress exercises that do not inhibit venous pooling.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Existing BFR methods involve tying a band around the desired limb. This existing method has the drawback that every time a user wants to incorporate BFR into their training, they have to find the correct position of the band on the limb and apply the pressure exerted by the band to the correct position where the main blood vessels are located. It can be difficult to correctly position the band on the desired muscle every time BFR is incorporated in order to correctly apply pressure to the main vein or otherwise (e.g., artery). Furthermore, the existing method has the drawback that the user has to find the correct pressure exerted by the band on the main vein every time they use it. It can be difficult to adjust the tension of the band to apply the correct amount of pressure and compress the main vein by the correct amount. A further drawback is that the band is obtrusive. If the user wants to do normal training without using the band, they have to carry the band around or put it in their pocket.

Means for Solving the Problem

[0004] In one aspect, there is provided a sports garment having an adjustable compression member for allowing blood flow through a major artery in a user's limb while compressing at least one major vein in the user's limb and restricting blood flow through the at least one major vein. (1) The garment is a top or T-shirt to be worn on the upper body. The compression member is provided on the sleeve of the top or T-shirt to be worn on the upper body. The compression member is disposed on the upper part of the user's arm close to the user's armpit during use. Or, (2) The garment is a pair of shorts or a pair of trousers. The compression member is provided on the leg portion of the pair of shorts or the pair of trousers. The compression member is disposed on the upper part of the user's thigh close to the user's groin during use.

[0005] The garment is designed to correctly position the compression member and restrict blood flow in at least one major vein in the user's upper arm or thigh without unduly restricting blood flow in the artery. This can result in faster muscle growth in the upper arm or thigh compared to exercise when wearing normal sports clothing.

[0006] The garment may include a sleeve or housing for accommodating a compression member that adjustably compresses at least one major vein. Thereby, for example, when the compression member is not being used to restrict blood flow, the compression member can be covered or hidden, and the garment can look like normal sports clothing. Also, it becomes more certain that the user has the option to use BFR at any time while wearing the garment. Separate BFR devices can be lost and may be inconvenient to carry around.

[0007] The sleeve or housing of the garment may be manufactured from the same fabric as the rest of the garment. This allows the garment to have a seamless appearance. Also, although the compression member is repeatedly pulled by the user during adjustment, this can improve the durability of the garment.

[0008] The compression member may comprise an elastic band. The elastic band is configured to be adjustable between a first configuration in which the compression member does not compress at least one major vein and a second configuration in which tension is applied to the elastic band and the elastic band compresses at least one major vein. The tension of the elastic band can result in compression of at least one major vein.

[0009] The elastic band may have a first end and a second end. At least one of the first end and the second end may be movable relative to the other of the first end and the second end to adjust the elastic band between the first configuration and the second configuration. This allows the elastic band to reliably remain in a tensioned state that continuously compresses the major vein when BFR is desired.

[0010] The first end of the elastic band may be fixed to the garment. The second end of the elastic band may be configured to be removably fixed to the garment. This allows the user to repeatedly switch the garment between a mode in which BFR is performed and a normal mode.

[0011] The second end of the elastic band may be configured to at least partially protrude from the housing when the elastic band is in the first configuration. This allows the user to easily grasp the elastic band and move it easily from the first configuration to the second configuration.

[0012] The second end portion may be configured to be removably fixed to the clothing by a hook-and-loop fastener. In one embodiment, one of the straps of the hook or loop portion of the hook-and-loop fastener may be attached to the outer surface of the sleeve or housing. Also, the other of the strap of the loop or hook portion may be close to the second end portion of the elastic band and may be attached to the inner surface of the elastic band. Thereby, the elastic band can be sufficiently joined to the sleeve or housing. Also, the hook-and-loop fastener has the advantage of being lightweight and having no inconvenient protrusions, i.e., being flat.

[0013] In some embodiments, at least one of the first end portion and the second end portion is connected to a rotary dial having a ratchet mechanism. By rotating the dial, tension can be applied to the elastic band. A suitable mechanism of this type is disclosed, for example, in WO 99 / 09850 with respect to a shoe lacing system, the content of which is incorporated herein by reference.

[0014] Furthermore, the clothing may have a mark indicating the amount of compression applied to at least one major vein by the compression member. In some embodiments, the amount of compression is a function of the amount of tension applied to the elastic band. For example, provide a mark in the form of markings along at least one length of the elastic band, the sleeve or housing, and / or the hook-and-loop fastener, or a mark in the form of markings around the rotary dial. Thereby, the user can record the position where the elastic band was comfortable and the tension was effective, and can easily reset the tension to the same degree when using the clothing later.

[0015] In some embodiments, the second end of the elastic band may be configured to be removably attached to the garment by a catch portion configured to engage one of a plurality of eyelets incorporated into the sleeve or housing. The catch portion may be attached to the inner surface of the elastic band proximate to the second end of the elastic band. This allows the elastic band to be removably secured to the sleeve or housing. Also, this configuration may have better aesthetics than loop-and-hook fasteners. Further, a logo of a sports garment may be embossed on the catch portion.

[0016] In some embodiments, a pad or protrusion may be provided on the lower surface of the elastic band at an appropriate position that restricts blood flow in at least one major vein but allows blood flow in the major artery, so as to apply additional pressure to the user's limb.

[0017] The pad or protrusion may be substantially solid, or in some embodiments, may be cushioned for comfort.

[0018] In some embodiments, the position of the pad or protrusion along the length of the elastic band may be adjustable by the user to enable correct placement. The pad or protrusion may be held in the correct position by a clip or other fixture.

Figure 11

[0021] FIG. 1 shows a T-shirt 100 having first and second sleeves 102. The first and second sleeves 102 each include an integrated adjustable strap 104. The integrated adjustable straps 104 on the first and second sleeves 102 may be substantially equivalent. The integrated adjustable strap 104 includes an elastic strap 108 within a housing 106.

[0022] The elastic band 108 may be manufactured from twill tape or rubber. In FIG. 1, the elastic band 108 is in a disengaged first position where it is relaxed and not compressing any major veins. The housing 106 is formed by folding the end of the sleeve 102 under the sleeve 102 itself and securing the edge of the end of the sleeve 102 inside the sleeve 102, for example, by sewing or adhering with a fabric adhesive.

[0023] The width of the housing should be substantially the width of the elastic band 108 or slightly wider than the elastic band 108. The width of the elastic band 108 may be 2 - 3 cm, preferably 2.5 cm. This width is sufficient to apply local pressure to the desired area, disperse the pressure on the surface of the associated limb, and reduce the pain of the limb.

[0024] In an alternative example, the housing 106 may be formed by sewing another fabric to the surface of the fabric of the T - shirt 100. The housing 106 serves to conceal the elastic band 108 such that the T - shirt 100 resembles an unmodified sports - wear T - shirt.

[0025] In FIG. 1, only the portion of the second end of the elastic band 108 is exposed. The first end, the middle portion, and the remaining portion of the second end are within the housing 106. The exposed portion of the second end functions as a tab 112 that can be easily grasped to hold and stretch the elastic band 108.

[0026] The tab 112 may be reinforced by folding the second end of the elastic band back on itself to double the thickness of the tab 112. The tab 112 may be reinforced by folding an elongated metal piece over the end of the tab. The elongated metal piece may be fixed to the tab 112 by a serrated portion. The serrated portion pierces the tab 112 at its end.

[0027] The first end is fixedly attached inside the housing 106. The first end may be looped through a metal buckle 103 (see FIG. 9) attached inside the housing 106 and sewn back onto itself on the metal buckle 103 (see FIG. 9) for attachment. Alternatively, the first end may be fixedly attached by directly sewing the second end to the clothing or by adhesion using an adhesive for fabric.

[0028] The second end may be inserted through a housing around the upper part of the user's biceps brachii and through the metal buckle 103 (see FIG. 9). The double-thickness tab 112 serves to prevent the second end of the elastic band 108 from retreating too far into the housing 106.

[0029] A releasable connector 110 for removably attaching the second end to the clothing, or a first part 110a (see FIG. 9) of the releasable connector 110, is fixedly attached to the second end. The clothing 100 may have a second part 110b of a releasable connector for removably attaching the second end to the clothing. The first part 110a (see FIG. 9) and the second part 110b of the releasable connector 110 for removably attaching the second end to the clothing have a hook-and-loop fastener 110, such as Velcro (registered trademark).

[0030] One of the loop part or the hook part of the hook-and-loop fastener 110, 110b, is disposed on the outer surface of the housing 106. The loop part of the hook-and-loop fastener 110 is preferably disposed on the outer surface of the housing 106. This prevents discomfort to the user who may come into contact with the second part 110b of the releasable connector 110 for removably attaching the second end when wearing a T-shirt 100.

[0031] The other one 110a (see FIG. 9) of the hook or loop portion of the hook-and-loop fastener 110 is attached to the outer surface of the second end portion of the elastic band 108. Thus, by engaging the hook portion 110a (see FIG. 9) and the loop portion 110b of the hook-and-loop fastener 110, the second end portion can be detachably attached to the sleeve 102 of the T-shirt.

[0032] The second end portion 112 may be detachably attached to the sleeve 102 of the T-shirt by using other methods. For example, the second end portion may have an eyelet, a button, or a popper attached to the outer surface of the elastic band 108 for engaging with a metal ring, and a buttonhole or a snap attached to the outer surface of the housing 106 in relation thereto.

[0033] FIG. 2 is a view showing a pair of shorts 200 each having a first and a second leg portion 202 with an integrated adjustable band portion 204. The integrated adjustable band portion 204 is substantially the same as the integrated adjustable band portion 104 described in the T-shirt 100 of FIG. 1.

[0034] The integrated adjustable band portion 204 includes an elastic band 208 in a housing 206. The first end portion of the elastic band 208 is attached in the housing 206. The outer surface of the second end portion of the elastic band 208 has a releasable connector 210, or a first portion 210a (see FIG. 9) of the releasable connector, which is detachably attached to the leg portion 202 of the pair of shorts 200. The second portion 210b of the releasable connector 210 for detachably attaching the elastic band 208 to the leg portion 202 may be attached to the outer surface of the housing 206.

[0035] Similar to the configuration described with reference to FIG. 1, the first end portion, the intermediate portion, and a part of the second end portion are within the housing 206. The exposed portion of the second end portion functions as a tab 212 that can be easily held and grasped to move the elastic band 208. The tab 212 may be reinforced by folding the second end portion of the elastic band back onto the second end portion itself and doubling the thickness of the tab 212.

[0036] The first end portion of the elastic band 208 is fixedly attached to the inside of the housing 206. The first end portion may be formed into a loop leading to a metal buckle 203 (see FIG. 9) attached to the inside of the housing 206 and sewn back onto itself on the metal buckle 203 (see FIG. 9) for attachment. Alternatively, the first end portion may be fixedly attached by directly sewing the second end portion to the clothing or by adhering it using an adhesive for fabric.

[0037] The second end portion may be inserted through the housing 206 around the upper part of the user's thigh and into the metal buckle 203 (see FIG. 9). The tab 212 with double thickness helps prevent the second end portion of the elastic band 208 from retreating too far into the housing 206.

[0038] In the example of FIG. 2, the releasable connector 210 for removably attaching the second end portion of the elastic band 208 to the leg portion 202 is a hook-and-loop fastener 210. The first part 210a (see FIG. 9) of the releasable connector for removably attaching the elastic band 208 to the leg portion 202 is preferably the hook portion of the hook-and-loop fastener. Also, the second part 210b of the hook-and-loop fastener is preferably the loop portion of the hook-and-loop fastener.

[0039] The integrated adjustable band portion 204 is disposed immediately below the crotch portions of a pair of shorts and is adapted to be located at the upper part of the thigh muscles when the pair of shorts is worn by a user. In the example of FIG. 2, the housing 206 is formed by sewing or adhering a piece of material onto a pair of shorts 200. In an alternative embodiment, the housing 206 can be formed by folding the ends of the legs 202 of a pair of shorts 200 under the legs 202 themselves and securing the edges of the ends of the legs 202 to the inside of the legs 202, for example, by sewing or using an adhesive for fabric.

[0040] The width of the end of the leg 202 to be folded under should be substantially the width of the elastic band 208 or slightly wider than the elastic band 208. The width of the elastic band 208 can be 2 to 3 cm, preferably 2.5 cm. In this configuration, the length of the leg 202 is such that the end of the leg 202 reaches the upper part of the thigh. In this way, the housing made in this manner results in a pair of shorts with short legs.

[0041] FIG. 3 is an enlarged view of the sleeve 102 of a T-shirt 100 having an integrated adjustable band portion 104. FIG. 3 shows the integrated adjustable band portion 104 in a first position where the elastic band 108 is not under tension. The length of the elastic band 108 may be changed according to the size of the T-shirt 100. A longer elastic band 108 is required for a user with a larger circumference around the biceps brachii than for a user with a smaller circumference. The integrated adjustable band portion 104 is disposed at the upper part of the biceps brachii close to the user's armpit when the user is wearing the T-shirt 100.

[0042] FIG. 4 shows where a user moves the elastic band 108 from a non - engaged first position where the elastic band 108 is relaxed to a second position where the elastic band 108 is under tension. The length of the elastic band 108 should be such that the elastic band 108 can be stretched and the first part 110a (see FIG. 9) of the hook - and - loop fastener 110 on the elastic band 108 can be engaged with the second part of the hook - and - loop fastener 110 on the housing 106.

[0043] The user moves the elastic band 108 from the non - engaged first position to the second position by pinching the tab 112 with the thumb and index finger and pulling the tab 112 away from the first end of the elastic band 108 which is fixedly attached. By moving the second end of the elastic band 108 and further separating it from the fixation of the first end of the elastic band 108, the amount of tension applied to the elastic band 108 can be adjusted.

[0044] FIG. 5 shows a T - shirt 100 to which the second end of the elastic band 108 is detachably attached. The first part 110a (see FIG. 9) and the second part 110b of the hook - and - loop fastener 110 are engaged, and the elastic band 108 is fixed under tension. In FIG. 5, the elastic band 108 is under tension so as to compress the main vein related to the biceps brachii covered by the band and reduce the blood flow through the main vein. The blood flow is preferably reduced to 40 - 50%.

[0045] The integrated adjustable band part 104 may be provided with a marker (not shown) along the length of the housing 106, the elastic band 108, and / or the hook - and - loop fastener 110 to indicate the amount of tension applied to the elastic band 108. In this way, the user can obtain a value regarding the amount of tension applied to the elastic band 108. This can provide the user with an easy way to return to the amount of tension applied to the elastic band 108 when later using the BFR of the sports clothing 100.

[0046] Figure 6 is an enlarged view of the leg portion 202 of a pair of shorts 200 with an integrated adjustable band portion 204. The elastic band 208 is in a first position without tension. The length of the elastic band 208 may be changed according to the size of the pair of shorts. A longer elastic band 208 is required for a user with a larger thigh circumference than for a user with a smaller thigh circumference. The adjustable band portion 204 integrated with the housing 206 is disposed at the upper part of the thigh close to the groin of the user when the user is wearing the pair of shorts.

[0047] Figure 7 shows where the user moves the elastic band 208 from a first position where the elastic band 208 is relaxed to a second position where the elastic band 208 is under tension. The user moves the elastic band 208 from the disengaged first position to the second position by pinching the tab 212 with the thumb and index finger and pulling it away from the first end of the elastic band 208 to which the tab 212 is fixedly attached. The compression on the major veins is preferably such that it limits blood flow to about 40 - 50% of the original flow rate. The amount of tension in the elastic band 208 can be adjusted by moving the second end of the elastic band 208 further away from the fixation of the first end of the elastic band 208.

[0048] Figure 8 shows where the user is wearing a pair of shorts 200 with the second end of the elastic band 208 removably attached. The length of the elastic band 208 should be such that when the first part 210a (see Figure 9) of the hook - and - loop fastener 210 on the elastic band 208 engages with the second part 210b of the hook - and - loop fastener 210 on the housing, the elastic band 208 is under tension. The elastic band is fixed in a tensioned state by the engagement of the hook - and - loop fastener 210.

[0049] The integrated adjustable band portion 204 may be provided with a marker (not shown) along the length of the housing 206, the elastic band 208, and / or the hook-and-loop fastener 210 to indicate the amount of tension applied to the elastic band 208. In this way, the user can obtain a value regarding the amount of tension applied to the elastic band 208. This can provide the user with an easy way to return to the amount of tension applied to the elastic band 208 when later using the BFR of the sports clothing 200.

[0050] FIG. 9 is a view showing the integrated adjustable band portions 104, 204 excluding the housings 106, 206 to more clearly illustrate the configuration of the elastic bands 108, 208. Metal buckles 103, 203 are attached to the housings. The first ends of the elastic bands 108, 208 are attached to the metal buckles 103, 203. This attachment may be achieved by sewing a loop of fabric around the bar of the buckle.

[0051] The elastic band is wound around the perimeter of an opening for a user's limb in the clothing and is inserted through the second bar of the metal buckles 103, 203. The tabs 112, 212 are thicker than the opening between the bars of the metal buckles 103, 203. The metal buckles 103, 203 can prevent the second ends of the elastic bands 108, 208 from retreating too far into the housings 106, 206. The first parts 110a, 210a of the releasable connectors for attaching the second ends to the clothing are attached to the outer surfaces of the elastic bands. This is such that when the elastic bands are folded back over the buckles, the first parts 110a, 210a engage the second parts 110b, 210b on the outer surfaces of the housings 106, 206.

[0052] Figure 10 is a diagram showing an alternative configuration for removably attaching the second ends of the elastic bands 108, 208 to the clothing 100, 200. The catch portions 105, 205 are configured to be hooked onto one of the plurality of eyelets 107, 207. The eyelets 107, 207 are arranged at an interval of distance d from the housings 106, 206. The eyelets 107, 207 are reinforced so as not to fray the material of the housings 106, 206 and to assist the force of the catch portions 105, 205 against the eyelets 107, 207.

[0053] The length of the catch portions 105, 205 is substantially equal to the width of the elastic bands 108, 208. This makes it possible to disperse the elastic force applied to the eyelets 107, 207 by the catch portions 105, 205 from the elastic bands 108, 208 along the length of the catch portions 105, 205 and prevent damage to the housings 106, 206. The radius of the catch portions 105, 205 may be 2 to 7 mm. This makes it possible to sufficiently attach to the eyelets 107, 207 without giving discomfort to the user due to the catch portions protruding to the user's skin.

[0054] The catch portions 105, 205 may be made of a metal such as aluminum or steel. The catch portions 105, 205 are preferably made of an oxidation-resistant metal. This can more reliably ensure the durability of the catch portions 105, 205 even in the presence of sweat that may occur from the user wearing the sports clothing 100, 200.

[0055] The eyelets 107, 207 may be reinforced by the reinforcing elements 109, 209, for example, by folding a thin piece of material around the eyelets 107, 207. This material is preferably an oxidation-resistant metal.

[0056] One catch portion 105, 205 and a plurality of eyelets 107, 207 may have better aesthetics than the loop-and-hook type fasteners 110, 210. Further, a logo of sports clothing may be embossed on one catch portion 105, 205 and / or the reinforcing element 109, 209.

[0057] As an alternative to the marker for indicating the amount of tension of the elastic bands 108, 208, the reinforced eyelets 107, 207 themselves may serve to indicate the amount of tension applied to the elastic bands. For example, the user can recall hooking the catch portion 105, 205 to the second eyelet 107 out of the possible three eyelets 107.

[0058] FIG. 11 is an enlarged view of the sleeve 102 of the T-shirt 100 provided with the integrated adjustable band portion 104. FIG. 11 shows the integrated adjustable band portion 104 in the first position where the elastic band 108 is not under tension. The length of the elastic band 108 may be changed according to the size of the T-shirt 100. A longer elastic band 108 is required for a user with a larger circumference around the biceps brachii than for a user with a smaller circumference. The integrated adjustable band portion 104 is disposed at the upper part of the biceps brachii close to the user's armpit when the user is wearing the T-shirt 100.

[0059] Tension can be applied to the elastic band 108 by rotating the dial 150 with a ratchet in the clockwise direction and winding the tensioning cord 151 around a spool (not shown) connected to the dial 150. The tensioning cord 151 is connected to the second end portion 112 of the elastic band 108. When the user wants to stop the BFR training after exercise, the dial 150 can be rotated counterclockwise to release the tension applied to the elastic band 108. The dial 150 is provided with a mark 152 to indicate to the user the amount of tension of the elastic band 108 and the degree of compression on at least one major vein.
