Description

  The present invention relates to a muscle building kit.

  It is known that strengthening muscles is very important for maintaining and improving health. In order to strengthen muscles, that is, to increase muscle mass, exercise such as strength training is generally performed. The strength training is performed while applying a high mechanical load to the muscle using a dumbbell or the like. However, it is difficult to perform sufficient strength training with high load. In recent years, it has been required to increase muscle mass more effectively regardless of exercise. Therefore, a muscle augmentation method (Patent Document 1) that increases the muscle mass by keeping the temperature of the muscle at 38 ° C. or more and 41 ° C. or less using a thermal load device, and the muscle enhancement that strengthens the muscle using the heat of the steam heating device. A tool etc. are proposed (patent document 2).

JP 2006-61687 A JP 2009-268618 A

However, since the method described in the above-described prior art document is a thermal device having a small heat application area like a portable hand warmer as described in Patent Document 1, heat cannot be effectively applied to muscles. There was a problem. Therefore, a large heat application area is required to increase muscle mass. In this case, if the heating range is wide, a heat load is applied to the human body, which tends to increase physical and mental burdens.
Thus, the present inventors have conducted extensive studies and found that muscle mass can be effectively increased by ingesting catechins orally and heating the local area of the human body.

According to the present invention, catechins for oral consumption;
There is provided a muscle strengthening kit including a heating means for heating a local body part of a user.

The sheets 112 and 113 are not particularly limited in type as long as they have air permeability, and preferably have stretchability. In particular, since the sheet 112 directly touches the wearer's body, it is preferable that the sheet 112 is made of a material having a good texture.

  As shown in FIG. 3, it is preferable that fixing means 115 for fixing the steam temperature heating tool 11 to the user's body is provided on the surface of the sheet 112 in the steam temperature heating tool 11. As the fixing means 115, for example, an adhesive such as a hot-melt pressure-sensitive adhesive can be used. Alternatively, the fixing means 115 may not be provided, and a wearing tool may be provided that has a pocket for inserting the steam heating tool 11 and is wound around and fixed to the user's body. In this case, the surface of the wearing tool that comes into contact with the skin of the wearer is such that water vapor generated from the steam heating device 11 hits the skin, and the surface opposite to the surface that comes into contact with the skin is supplied with air to the steam heating device 11.

  Of the heat generating sheet and the heat generating powder, it is preferable to use the heat generating sheet because water vapor can be uniformly applied to any posture of the user. Further, the heat generating sheet is more advantageous than the heat generating powder because the temperature distribution of heat generation can be made uniform easily and the ability to support an oxidizable metal is excellent.

  The heat generating part 116 may be blended with a cooling sensation agent that imparts a refreshing feeling to the skin, such as menthol. By supplying a cooling sensation agent along with water vapor to the skin, it can give a refreshing feeling to the skin, so even in environments where it is easy to feel hot feeling such as in summer, usability is maintained while maintaining the muscle strengthening effect due to heat.

  As various materials constituting the heat generating sheet and the heat generating powder, the same materials as those usually used in the technical field can be used. Further, the materials described in JP-A-2003-102761 described above can also be used.

Note that the heat generating portion 116 may be formed by a coating method. In this case, an exothermic composition containing an oxidizable metal, a reaction accelerator (carbon component), and water may be applied on the base material layer.
The base material layer can absorb and retain moisture, and a flexible sheet material is used. As a base material layer, what has air permeability is preferable. As such a material, for example, any fiber sheet such as a non-woven fabric or a woven fabric made of fibers is used.
Examples of the fibers include those mainly composed of natural fibers such as plant fibers and animal fibers, and those mainly composed of chemical fibers. Especially, as a base material layer, what contains the fiber sheet comprised with the fiber mentioned above and a water absorbing polymer is preferable.

The first surface 118 of the water vapor generator 117 has air permeability so that air and water vapor can pass therethrough. On the other hand, the second surface 119 has a lower degree of air and water vapor transmission than the first surface 118. That is, the second surface 119 is less breathable or non-breathable than the first surface 118. Whether the second surface 119 is breathable or non-breathable is appropriately selected according to the specific application of the steam heating device 11.
The steam generator 117 is used such that the first surface 118 side faces the wearer's skin side and the second surface 119 side faces the clothing side (outside). The cooling agent release component such as water vapor or menthol generated by the heat generation of the heat generating part 116 passes through the first surface 118 and is applied to the skin of the wearer as the object.

  Both the first surface 118 and the second surface 119 of the water vapor generator 117 are made of a sheet material. The water vapor generator 117 has a peripheral edge joint 120 having a closed shape formed by joining the peripheral edges of the sheet materials constituting the first surface 118 and the second surface 119 to each other at the periphery. Yes. The peripheral joint 120 is formed continuously. In the steam generator 117, the first surface 118 and the second surface 119 are in a non-joined state at a portion inside the peripheral joint 120. Accordingly, a single bag-like space for accommodating the heat generating portion 116 is formed in the water vapor generator 117.

The water vapor generator 117 is configured such that water vapor is preferentially released through the first surface 118 by appropriately adjusting the air permeability of the first surface 118 and the second surface 119. Specifically, the air permeability of the second surface 119 is greater than the air permeability of the first surface 118. Here, the air permeability is a value measured by JIS P8117, and is defined as the time required for 100 ml of air to pass through an area of 6.45 cm ² under a constant pressure. Therefore, a high air permeability means that it takes time to pass air, that is, the air permeability is low. Conversely, a low air permeability means high air permeability. Thus, the magnitude of the air permeability and the level of air permeability are opposite to each other. In the present embodiment, when the air permeability of the first surface 118 and the second surface 119 is compared, the first surface 118 is higher than the second surface 119. That is, as described above, the second surface 119 is non-breathable or hardly breathable (that is, it has breathability but is less breathable than the first surface 118). It is.

  The specific range of the air permeability of the first surface 118 in the steam generator 117 is preferably 1000 to 30000 seconds / 100 ml, more preferably 2000 to 30000 seconds / 100 ml, and more preferably 5000 to 25000 seconds. Particularly preferred is / 100 ml. The specific air permeability of the second surface 119 in the water vapor generator 117 is preferably 30000 seconds / 100 ml or more, more preferably 40000 seconds / 100 ml or more, and 50000 seconds / 100 ml or more. Is even more preferred.

  The water vapor generator 117 has a flat shape having a first surface 118 that is a ventilation surface and a second surface 119 that is a non-venting surface opposite to the first surface 118, and the first surface 118 that is a ventilation surface. Steam temperature and heat are generated through it. Alternatively, the water vapor generator 117 has a flat shape having a first surface 118 which is a ventilation surface and a second surface 119 which is a difficult ventilation surface facing the first surface 118, and is a first surface which is a ventilation surface. Steam heat is generated through the surface 118. When the second surface 119 is difficult to breathe, the air is preferentially passed into the water vapor generator 117 through the second surface 119 by balancing the air permeability of the first surface 118 and the second surface 119. As it flows in, water vapor is preferentially released through the first surface 118.

When the second surface 119 is difficult to breathe, the second surface 119 is used from the viewpoint of suppressing the release of water vapor through the second surface 119 while ensuring the inflow of air through the second surface 119. It is preferable that the air permeability of 119 is 1.5 times or more, particularly 2 times or more than the air permeability of the first surface 118. Alternatively, the ratio of the air permeability of the first surface 118 and the air permeability of the second surface 119 (first surface / second surface) is preferably 0.7 or less, particularly 0.4 or less. As a result, the water vapor emission through the second surface 119 can be further reduced, and the water vapor emission through the first surface 118 can be further increased. On the other hand, when the second surface 119 is non-breathable, the inflow of air into the water vapor generator 117 and the generation of water vapor are performed exclusively through the first surface 118.
Both the first surface 118 and the second surface 119 of the water vapor generator 117 are made of a sheet material. As the sheet material that controls the air permeability and prevents the powder from leaking out, a moisture permeable film or a melt blown nonwoven fabric is preferably used. The moisture-permeable film is obtained by forming a melt-kneaded product of a thermoplastic resin and an organic or inorganic filler that is not compatible with the resin into a film shape and stretching it uniaxially or biaxially. It has a structure. By configuring a laminated sheet by combining sheet materials having various air permeability and moisture permeability, the degree of freedom for setting the air permeability of the first surface 118 and the second surface 119 to a desired value is increased.

  The steam heating tool 11 as described above is hermetically housed in a packaging bag 12 (see FIG. 1) having oxygen barrier properties until just before use.

(how to use)
Next, the usage method of the muscle strengthening kit 1 of this embodiment is demonstrated. Here, the steam heating tool 11 is used as a heating means, and the heat generating part 116 of the steam heating tool 11 is a heat generating sheet, and an example in which it is attached to a leg part will be described.

Paste on the upper knee. The steam heating tool 11 may be attached to both legs of the user, or the steam heating tool 11 may be attached only to one leg. From the top of the heat generating sheet, in order to prevent the heat generating sheet from being peeled off from the local area of the human body and falling off, it is possible to attach a breathable supporter S that does not inhibit the heat generation of the heat generating sheet as shown in FIG. preferable. The supporter S is preferably made of a stretchable material such as nylon, polyurethane, or polyester. In addition, when the heat-retaining and breathable supporter S, which is made of wool or moisture-absorbing heat-generating fiber, is attached, the heat-retaining effect is enhanced in addition to the heat generation of the heat-generating sheet, and the transmission of heat to the muscle becomes more effective.

  Moreover, only one steam heating tool 11 may be affixed with respect to a user's one leg part, and as shown in FIG. Moreover, you may affix the vapor | steam heating tool 11 to the multiple places of a human body local.

When the user's body part is heated by the steam heating tool 11, the heating area is preferably 20 cm ² or more, and more preferably 40 cm ² or more. The heating area is preferably 200 cm ² or less, and more preferably 100 cm ² or less. Among them, it is preferable that the heating area is 20～200Cm ^2, it is preferred that especially 40~100cm ^2.
By setting the heating area to 20 cm ² or more, a sufficient muscle weight gain effect can be obtained. On the other hand, heat stress (such as hot flashes) can be reduced by setting the heating area to 200 cm ² or less. Moreover, even if the heating area is relatively small, such as 200 cm ² or less, a sufficient muscle weight gain effect can be obtained.
Note that the heating area indicates the total value of the areas of the heat generating parts 116 when heating with a plurality of steam heating tools 11, and when there are a plurality of steam heating tools 11, the heating of each steam heating tool 11. The total value of the area of the part 116 is shown.

In addition, users take catechins orally. Either the local heating of the human body or the oral intake of catechins may be first, but from the viewpoint of exerting a sufficient muscle strengthening effect, the state where the human local body is heated with the steam heating device 11 and the blood concentration of catechins is high. It is preferable that the catechins are orally ingested so that the blood concentration of the catechins becomes higher after the skin temperature is increased and the blood concentration of the catechins is increased. More preferably, the catechins are orally ingested so that the skin temperature always rises while the blood concentration is high.
The intake of catechins is preferably 300 mg / day or more, and more preferably 400 mg / day or more, from the viewpoint of exerting a sufficient muscle increasing effect. More preferably, it is 500 mg / day or more. The intake of catechins is preferably 1000 mg / day or less, and more preferably 800 mg / day or less. More preferably, it is 700 mg / day or less. Of these, the intake of catechins is preferably 300 to 1000 mg / day, and more preferably 400 to 800 mg / day. Especially, it is preferable that it is 500-700 mg / day or less.
Here, it is preferable that the user orally ingests the above-mentioned daily intake of catechins in a state where the skin temperature immediately below the heating part 116 of the steam heating device 11 is 38 ° C. or higher.
Especially, it is preferable that a user orally ingests the catechin of the daily intake mentioned above in the state which heated the human body local area with the steam heating tool 11.
Furthermore, catechins are preferably taken orally within the entire daily intake within one hour, preferably within 30 minutes, in order to increase the blood concentration.
By doing in this way, sufficient muscle weight gain effect can be acquired. When the concentration of catechins in the user's blood is increased, the muscle is heated by the steam heating device 11, so that the uptake of catechins into the muscle tissue is promoted, and the effect of increasing the muscles due to the heat and catechin is increased. It is thought that can be further increased.

The heating time by the steam heating tool 11 is preferably 2 hours or more and 12 hours or less. Especially, it is preferable to maintain the state in which the skin temperature of the user's local body becomes 38 ° C. or higher for 2 hours or more and 12 hours or less after catechin intake. By heating for 2 hours or more, it is considered that the circulation of muscle is promoted by the heat, the catechins can be sufficiently taken into the muscle tissue, and a sufficient muscle weight-increasing effect can be exhibited. Moreover, a user's burden and the risk of a low-temperature burn can be reduced by making heating time into 12 hours or less.
The skin temperature can be measured, for example, with a thermometer (LT-8) manufactured by Gram Co., Ltd. The skin temperature here is the temperature of the skin surface immediately below the heat generating portion 116 of the steam heating device 11.
Further, the user is preferably a healthy person who has exercise habits, and the degree of exercise habits is more preferably that exercise such as walking for 30 minutes or more is performed for 2 days or more per week.

Here, the conventional technical level will be described.
Patent Document 1 discloses a technique for increasing the amount of muscle using the heat of a thermal load device, but in this technique, a thermal apparatus with a small heat application area such as a portable hand warmer is effective for muscles. It is difficult to increase the amount. Further, Patent Document 2 discloses a muscle strengthening device that reinforces muscles by using the heat of the steam heating device. However, in order to obtain an effect, a certain extent of heating area is required.
Catechins are known to have antioxidant activity, and have the effect of preventing cell and gene damage from active oxygen and free radicals. For example, JP 2008-13473 A discloses the use of catechins as muscle function lowering inhibitors. However, this is only an action for preventing muscle oxidation, and is totally different from increasing the muscle mass to catechins. It has never been known at all that catechins have the effect of increasing muscle mass.
On the other hand, the present inventors have found that the muscle mass can be effectively increased by heating the user's local body with the steam heating device 11 and orally ingesting catechins. And the muscle enhancement kit provided with the catechin for ingestion and the steam heating tool 11 was invented. As a result, the muscle mass can be effectively increased without excessive exercise. Therefore, even a person with limited exercise such as an elderly person can easily increase muscle mass.
