Description

Underwater strength training belt

The present invention relates to an underwater strength training belt.

Conventionally, a pressurized muscle strength training method capable of efficiently strengthening muscles by applying a load due to appropriate blood flow restriction to the muscles has been proposed and put into practical use (for example, see Patent Document 1). In such a strength training method, a muscle strengthening device is used in which a predetermined portion of a user's limb (arm or leg) is tightened with a tightening tool to apply pressure to the muscle.

Japanese Patent No. 2670421

By the way, at present, methods relating to training and rehabilitation using resistance and buoyancy acting in water have been proposed. Underwater training methods that athletes have traditionally adopted include swimming with an object that generates a large amount of resistance underwater (for example, a bucket) attached to the body via a rope, or swimming against the flow of water. A method or the like is employed, and according to such a method, a load can be intentionally applied to a user (a person who receives training).

However, the conventional underwater training method as described above has a problem that the blood lactate concentration of the user cannot be increased efficiently even though large tools and equipment are required. In order to strengthen muscles, it is necessary to secrete more growth hormone from the pituitary gland than usual. For this purpose, it is necessary to efficiently increase the blood lactate concentration. The inventor of the present application has found that muscles can be reinforced very efficiently by combining a conventional pressurized muscle strength training method as described in Patent Document 1 and a method relating to training in water. Recently, we have developed an optimal belt for such underwater pressure training.

The object of the present invention is to provide a belt that is optimal for pressurized muscle strength training in water.

In order to achieve the above object, the underwater strength training belt according to the present invention applies a predetermined pressure to a specific part of the user's extremity in water without restricting the blood flow of the user's muscle. Is used for training muscles, and is configured to be wound around a specific portion and has a stretchable first belt-like member, and is disposed inside the first belt-like member and has a length around the specific portion. A gas bag having a corresponding specific length, a second strip member connected to one end of the first strip member, a buckle connected to the other end of the first strip member, and a first strip A first surface fastener provided on at least a part of the surface of the member, and a second surface fastener provided on substantially the entire surface of the second belt member, and looping the first belt member around a specific portion Form the shape One end of the second belt member and the first belt member is passed through the buckle, the first belt member is folded back, and the first surface fastener and the second surface fastener are joined together to maintain the loop shape, It is comprised so that the applied pressure based on the quantity of the gas in a bag may be provided to a specific part.

When such a configuration is adopted, the first strip member is wound around a specific portion to form a loop shape, and one end of the second strip member and the first strip member is passed through the buckle, and the first strip member is provided on the first strip member. Based on the amount of gas in the gas bag in a state in which the loop shape is reliably maintained by combining the one-surface fastener and the second-surface fastener provided on substantially the entire surface of the second belt-shaped member. The applied pressure can be applied to the specific portion. By adopting a method of folding and fixing the belt in this way, the belt is attached to a specific part of the user without being bulky, so that it is possible to reduce water resistance during underwater motion. Moreover, since the gas bag which has the specific length equivalent to the circumference of a specific part is employ | adopted, a pressurizing force can be provided to the whole circumference | surroundings of a specific part. Furthermore, since the first belt-shaped member has elasticity, the belt can be expanded and contracted in accordance with the expansion and contraction of the user's muscle accompanying the underwater exercise, and the applied pressure can be stably applied. .

In the underwater strength training belt according to the present invention, a flexible piece can be provided on the inner surface of the buckle.

When such a configuration is adopted, a flexible small piece made of, for example, leather or cloth is provided on the inner surface of the buckle (the surface located on the user's skin side), so that the user's skin passes through the buckle. It is possible to prevent the belt from being caught in the buckle together with a part of the belt.

Inside the first belt-like member of the underwater strength training belt according to the present invention, a plurality of plate-like pieces are arranged at predetermined intervals along the length direction of the first belt-like member outside the gas bag. Can do.

By adopting such a configuration, it is possible to prevent the gas bag from expanding to the outside (the side far from the specific portion when the belt is fixed to the specific portion of the user) by the plurality of plate-shaped small pieces. Therefore, the gas bag can be inflated inside (the side close to the specific portion when the belt is fixed to the specific portion of the user), and the applied pressure can be efficiently applied to the specific portion of the user.

In the first belt-like member of the underwater strength training belt according to the present invention, a non-stretchable tape is attached to the outer surface of the plate-shaped piece, and both end portions of the tape are attached to both widthwise end portions of the first belt-like member. Each can be attached.

If such a configuration is adopted, the movement of the plate-shaped piece itself to the outside is prevented due to the presence of the tape, so that the expansion of the gas bag to the outside can be more effectively prevented. Moreover, since the tape is non-stretchable, the gas bag can be prevented from expanding in the width direction. In addition, since a tape will be arrange | positioned at predetermined intervals along the length direction of a 1st strip | belt-shaped member with a plate-shaped piece, at least the part located between tapes among 1st strip | belt-shaped members is 1st. Expansion and contraction is possible in the length direction of the belt-shaped member. Therefore, the expansion and contraction of the first strip member is not hindered by the presence of the tape.

According to the present invention, it is possible to provide an optimum belt for pressurized muscle strength training in water.

Note that the number of belts 1 is not necessarily four, and may be any number as long as it is one or more. The number of arm belts 1 and leg belts 1 are not necessarily the same.

The length and width of the belt 1 can be appropriately set according to the length of the outer periphery of the portion to be wound (specific portion). For example, in the case of the belt 1 for the arm, the length of the outer periphery of the specific part of the arm (about 26 cm) can be taken into consideration, and the length can be set to about 40 cm. Can be set. In addition, the leg belt 1 can be set to a length of about 70 cm in consideration of the length (about 45 cm) of the outer periphery of a specific portion of the leg, and can be set to a width of 5.0 to 6.0 cm. Can be set.

The length of the first belt-like member 10 can be set to about 80 to 90% of the entire length of the belt 1. As shown in FIG. 1 and the like, a first surface fastener 50 is provided on the outer surface (surface exposed to the outside) 13 of the first strip member 10. The first surface fastener 50 maintains the loop shape of the belt 1 in a state where pressure is applied to the muscle. The position where the first surface fastener 50 is provided can be appropriately set according to the length of the belt 1 or the like. A first surface fastener 50 may be provided on the inner surface 14 of the belt 1. The first belt-like member 10 is made of a material (for example, neoprene rubber) that has water repellency, water resistance and quick-drying properties and also has stretchability.

The length of the second belt-like member 20 can be set to about 10 to 20% of the entire length of the belt 1. The width of the second strip member 20 can be set to the same width as the first strip member 10 (or a width slightly narrower than the width of the first strip member 10). As shown in FIG. 1 etc., the 2nd surface fastener 60 is provided in the substantially whole outer surface (surface exposed outside) of the 2nd strip | belt-shaped member 20. As shown in FIG. The second surface fastener 60 is connected to the first surface fastener 50 of the first strip member 10 to maintain the loop shape of the belt 1 in a state where pressure is applied to the muscle. The second belt-like member 20 is made of a non-stretchable material (for example, a cloth or a synthetic resin film material) having water repellency, water resistance and quick drying.

The gas bag 30 is an airtight elongated bag having elasticity in at least the length direction thereof. The gas bag 30 is not necessarily limited to this, but can be made of rubber having elasticity similar to that of a rubber bag used for a manchette, for example. The gas bag 30 is connected to a control device (not shown) via a connecting pipe 31 (FIG. 1 and the like). Air is fed into the gas bag 30 from the control device via the connecting pipe 31, and the air inside the gas bag 30 is extracted by the control device. Such a flow of air in and out of the gas bag 30 can be performed by a control device.

The length of the gas bag 30 is assumed to have a specific length corresponding to the length of the outer periphery of the portion to be wound (specific portion). For example, in the case of the belt 1 for the arm, a gas bag 30 having a length of about 26 cm corresponding to the length of the outer periphery of the specific part of the arm is adopted, and in the case of the belt 1 for the leg, the specific part of the leg is used. A gas bag 30 having a length of about 45 cm corresponding to the length of the outer circumference can be employed.

Inside the first strip member 10, a plurality of small plate-like pieces 70 are arranged outside the gas bag 30 at a predetermined interval along the length direction of the first strip member 10, as shown in FIGS. 4 and 5. Are arranged. The plate-shaped small piece 70 is a member for restricting inward the direction of expansion of the gas bag 30 that expands when air is introduced. The plate-shaped small piece 70 is made of a hard material (for example, synthetic resin) that can exhibit such a function. In the present embodiment, as shown in FIG. 5, a plurality of small plate-like pieces 70 having a rectangular shape in plan view are employed, but the planar shape of the small plate-like pieces 70 is not limited to this, and each plate-like piece is not limited to this. The planar shape of the small piece 70 may be different. The lateral length of the plate-shaped piece 70 (dimension in the width direction of the belt 1) can be set in a range of 60 to 100% of the width of the belt 1, and the length of the plate-shaped piece 70 in the vertical direction ( The dimension in the length direction of the belt 1) can be set to be approximately the same as the length in the lateral direction.

Also, a tape 80 is attached to the outer surface of the plate-shaped piece 70 inside the first strip member 10. As shown in FIG. 5, the tape 80 is a band-shaped member extending in the width direction of the first band-shaped member 10, and both end portions thereof are respectively attached to both width-direction end portions of the first band-shaped member 10. . The tape 80 is made of a non-stretchable material (for example, cloth or synthetic resin film material). The length of the tape 80 (the dimension in the width direction of the belt 1) can be set to be substantially the same as the width of the belt 1, and the width of the tape 80 (the dimension in the length direction of the belt 1) is the plate-shaped piece 70. It can be set to be shorter than the length in the vertical direction. The tape 80 is fixed to the outer surface of the plate-shaped piece 70 at a substantially central portion in the length direction. The tape 80 and the plate-shaped piece 70 can be fixed by, for example, adhesion, welding, stitching, or the like.

The buckle 40 is for folding the belt 1 through the other end 11 of the belt 1 when the belt 1 is wound. As shown in FIGS. 2 to 4, a flexible small piece 90 made of a soft material (for example, skin or cloth) is disposed on the inner surface of the buckle 40 (surface located on the user's skin side). ing. The flexible piece 90 prevents the user's skin from being caught in the buckle 40 (along with a portion of the belt 1 passed through the buckle 40) when the belt 1 is tightened to apply pressure. be able to.

Next, with reference to the flowchart of FIG. 7 and the like, each process of pressurized muscle strength training in water using the belt 1 according to the present embodiment will be described.

First, the belt 1 is wound around a portion (specific portion) close to the heart of at least one of the four limbs including the muscle for which the user wants to increase muscles (for example, the left upper arm including the biceps) (belt winding step: S1). . At this time, the first belt-like member 10 of the belt 1 is wound around a specific portion to form a loop shape, and one end 11 of the second belt-like member 20 and the first belt-like member 10 is passed through the buckle 40, and the first belt-like member 10 is folded and the first surface fastener 50 and the second surface fastener 60 are joined together to maintain the loop shape.

Next, by supplying air from the control device (not shown) to the inside of the gas bag 30 through the connection pipe 31, a pressure based on the amount of gas in the gas bag 30 is applied to the specific portion (pressure force). Application process: S2). The magnitude of the applied pressure can be set as appropriate according to the age, sex, exercise experience, etc. of the user, but it should be an appropriate value that can be limited without stopping the blood flow of the user's muscles. To do.

Thereafter, the user performs an underwater exercise while maintaining the applied pressure applied to the muscle by the belt 1 (underwater exercise process: S3). Water resistance and buoyancy act on the user by the underwater motion process S3. The type and duration of the underwater exercise can be appropriately set according to the age, sex, exercise experience, etc. of the user. Underwater exercises are not limited to swimming exercises, but other exercises in the water (walking exercises, squat exercises, butterfly movements and kicking exercises held by the pool, calf raise exercises, leg curl exercises, legs Extension exercise).

In the belt 1 according to the embodiment described above, the first belt-like member 10 is wound around a specific portion to form a loop shape, and one end 11 of the second belt-like member 20 and the first belt-like member 10 is used as the buckle 40. Through the first surface fastener 50 provided on the surface of the first belt member 10 and the second surface fastener 60 provided on substantially the entire surface of the second belt member 20, the loop shape is obtained. In a state where the gas bag 30 is reliably maintained, a pressing force based on the amount of gas in the gas bag 30 can be applied to the specific portion. By adopting the method of folding and fixing the belt 1 in this way, the belt 1 is attached to a specific part of the user without being bulky, so that it is possible to reduce water resistance during underwater motion. Moreover, since the gas bag 30 having a specific length corresponding to the peripheral length of the specific portion is employed, it is possible to apply pressure to the entire periphery of the specific portion. Furthermore, since the first belt-like member 10 has elasticity, the belt 1 can be expanded and contracted according to the expansion and contraction of the user's muscle accompanying the underwater exercise, and the applied pressure can be stably applied. It becomes.

Further, in the belt 1 according to the embodiment described above, the flexible small piece 90 made of, for example, leather or cloth is provided on the inner surface of the buckle 40 (the surface located on the user's skin side). It is possible to prevent the user's skin from being caught in the buckle 40 together with a part of the belt 1 passed through the buckle 40.

Moreover, in the belt 1 according to the embodiment described above, the gas bag 30 can be prevented from expanding to the outside by the plurality of small plate-like pieces 70. Therefore, the gas bag 30 can be inflated inward, and a pressure can be efficiently applied to a specific portion of the user.

Further, in the belt 1 according to the embodiment described above, since the movement of the plate-shaped piece 70 itself to the outside is prevented by the presence of the tape 80, the expansion of the gas bag 30 to the outside is more effectively prevented. be able to. Further, since the tape 80 is non-stretchable, the gas bag 30 can be prevented from expanding in the width direction. Note that the tape 80 is disposed at a predetermined interval along the length direction of the first band-shaped member 10 together with the plate-shaped pieces 70, so that the tape 80 is positioned at least between the tapes 80 in the first band-shaped member 10. The portion to be stretched can be expanded and contracted in the length direction of the first strip member 10. Therefore, the expansion and contraction of the first strip member 10 is not hindered by the presence of the tape 80.
