Description

  The present invention relates to a training tool to be worn on the lower body of a person, and in particular, can eliminate wasteful use of the quadriceps, which is a brake muscle, and can effectively operate hamstrings, which are accelerator muscles, such as walking and running. The present invention relates to a training tool that allows the body to learn how to efficiently use muscles in lower body exercise.

  General sports enthusiasts and amateur athletes tend to use unnecessary muscles excessively when exercising their lower body, such as walking and running, and hinder their natural and efficient exercise. It is done. In collaboration with sports science expert Hideo Takaoka and sports writer Hiroshi Matsui “Soccer Training to Become a World Class” (Publisher: Media Factory Co., Ltd., hereinafter referred to simply as “The Book”) The inefficient running method using the useless muscles is called “Thigh Forward”, and the problem is pointed out as follows.

  FIG. 8A to FIG. 8C are schematic diagrams showing a series of operations of “running thighs”. In the figure, the solid line circle indicates the knee bend, the black chain ellipse indicates the quadriceps muscle which is the “front muscle”, and the alternate long and short dash line indicates the position of the waist.

  First, FIG. 8 (a) shows the motion when the runner lands, and the book states that “the knee is bent and the weight is supported in front of the left leg on the ground. , "I am braking."

  Regarding the operation of FIG. 8 (b) that follows, the same book states that “the knee joint of the left leg is extended and the body is pushed forward by the force of pushing the ground”, “at the same time, “Since muscles are also raised, speed and cut are dull.”, “A waist position is higher immediately after the left leg touches the ground” in FIG.

  Finally, as for the operation of FIG. 8 (c), the same book states: “The knee is bent and the right leg is put on the ground. Therefore, the trunk remains behind and the waist is not carried smoothly. Immediately after (b) in the figure, "From the moment when the left knee is extended the most, the position of the waist is lowered again." Then, as shown in (a) in the figure, "Because the waist is lowered again, "It will be a run that moves up and down."

Summarizing the above-mentioned problems of “running forward”, the following A to D are obtained.
A: Landing with the knees bent B: Using the quadriceps muscle, which is the “front muscle”, wastefully C: The trunk remains behind and the waist cannot be carried smoothly D: The position of the waist moves up and down

  Here, the quadriceps, which is the “front muscle”, is a muscle located on the front side of the thigh (thigh), and is a straight thigh, lateral vastus, medial vastus, or intermediate vastus. One included. The quadriceps muscle is a muscle that connects the pelvis, the femur, and the tibia. When the quadriceps muscle contracts, a force for extending the knee joint is generated. Further, the rectus femoris muscle among the quadriceps muscles is connected to the pelvis and, together with the iliopsoas muscle, generates a force for bending the hip joint. For example, when raising the thigh as in the “thigh raising exercise”, the rectus femoris muscle plays a role of bending the hip joint.

  In the lower body exercise such as walking and running, it is not necessary to use the quadriceps muscle excessively to flex the hip and knee joints. It bends and the knee joint naturally bends following this. The above problems A to D are all caused by the useless use of the quadriceps, which hinders efficient exercise. Hereinafter, the relationship between the problems A to D and the useless use of the quadriceps will be described in detail.

<About Problem A>
The quadriceps muscle produces muscle strength as a so-called “leg spring”, but as shown in FIG. 8 (a), it landed with the knee joint of the left leg bent, and the quadriceps If used as a spring to support weight, this will be a brake that slows down the speed.

<About Problem B>
As shown in FIG. 8B, the hip and knee joints are extended using the quadriceps of the left leg, and at the same time, the hip joint is bent and thickened using the quadriceps of the right leg. Raising the thigh. Since the quadriceps muscles of both legs are used at the same time, the speed and cut are slow.

<About Problem C>
As shown in FIG. 8 (c), the trunk remains behind because it is going to land with the hip and knee joints of the right leg bent. In this case, the cause is that the quadriceps tend to support weight.

<Regarding Problem D>
As shown in FIGS. 8 (a) to 8 (c), the position of the waist during running is also raised and lowered by flexing the hip and knee joints using the quadriceps spring during landing and advancement. It is caused by extension.

<Solution Problems of the Present Invention>
Later, we will explain with reference to FIGS. 7 (a) to 7 (c). In the book “Soccer training to become a world class”, the quadriceps muscle, which is the “front muscle”, is wasted. Firstly, the “high-back running” using hamstrings, which is the “muscle behind the thigh”, is described as the most efficient way to run.

  However, the quadriceps muscles on the front side of the thigh are muscles that are frequently used to control leg strength and are the largest muscles in the human body. In contrast, hamstrings on the back side of the thigh are muscles used to extend the hip joint and flex the knee joint, and are often used in daily life and sports that often move the body forward. There is no muscle. For this reason, hamstrings are generally said to be hard and tend to shrink. Therefore, general sports enthusiasts and amateur athletes do not use the quadriceps that are frequently used in daily life and sports, but use hamstrings that are not often used. It is extremely difficult.

  Also, even if you can go to a gym and train hamstrings using specialized training equipment under the guidance of a professional instructor, teach the body how to use hamstrings in actual exercise. It ’s difficult.

  In addition, Patent Documents 1 to 3 disclose clothes and bands having a configuration in which a stretchable belt-like body is spirally wound around the body, but the clothes and bands of Patent Documents 1 to 3 are postures of a human body. The above-mentioned problems A to D in the lower body exercise are not solved at all.

  The present invention has been made in view of the above problems, and eliminates the wasteful use of quadriceps muscles, and is a training tool that can teach the body about efficient lower body exercise that uses hamstrings. For the purpose of provision.

(2) Preferably, the training tool of the above (1) is composed of a stretchable band member, and is continuous with a first first annular portion forming the first belt-like body and one side of the first annular portion. A second annular portion that forms the second belt-like body and a third annular portion that is continuous with the other side of the first annular portion and forms the third belt-like body may be provided.

(3) Preferably, in the training tool of (2), when the band member is composed of a single piece and both ends of the band member are connected to each other via a buckle part for adjusting the length. Good.

(4) Preferably, in the training tool of the above (2) or (3), the training tool includes a stop rubber capable of inserting and holding the band member, and a boundary portion between the first annular portion and the second annular portion The boundary portions between the first annular portion and the third annular portion are preferably held by the retaining rubber.

(5) Preferably, in the training tool according to any one of the above (2) to (4), the second and third annular portions may each be provided with a footrest strap that hangs on the sole.

(6) Preferably, in the training tool according to any one of the above (2) to (5), the strap for the footrest is made of a flat band-shaped body, and the front or back surfaces of both ends of the band-shaped body are made to face each other. It is good to make it the structure which joined and the said strap for legrests was made to surface-contact with a shin.

(7) Preferably, in the training tool according to any one of the above (2) to (4), the second and third annular portions are respectively intersected on the front side of the shin to form a small ring, and each small ring is It is good also as a structure each hung on a sole.

<First Embodiment>
First, as a first embodiment of the present invention, a band-shaped training tool will be described with reference to FIGS.

<< Overall structure >>
In FIG. 1, the training tool 1 of the present embodiment connects one end of each band member 10 with a buckle 20 to form one large annular shape, and two left and right portions of the large annular band member 10. The entire structure is formed into three large and small rings, and the left and right intersecting portions are fixed by a pair of retaining rubbers 30 and 30.

The three large and small rings of the band member 10 are divided into a small first annular portion (first strip) 11 located in the center in the figure and a large second annular portion (second strip) located on the right side in the figure. ) 12 and a large third annular portion (third strip) 13 located on the left side in the drawing. The small first annular portion 11 is mounted around the waist (waist) of the user. The large second and third annular portions 12 and 13 are wound around the pelvis and legs below the waist. The second and third annular portions 12 and 13 are respectively connected to the straps 50 and 50 for hanging on the soles in a chain shape.

<< Band member >>
In FIG. 1, a band member 10 is a single band-like body having elasticity, and for example, a plain weave rubber having a configuration in which weft yarns are woven into warp yarns (warp yarns) and yarn rubbers in the length direction. The lateral width of the band member 10 is not particularly limited, but as the lateral width is increased, the pressure when closely attached to the body can be dispersed, and the wearing feeling of the training tool 1 can be improved. .

  In this embodiment, a plain woven rubber having a total length of 550 mm and a width of 100 mm is used as the band member 10. If the overall length of the band member 10 is 550 mm, it can correspond to various heights of a person within a generally assumed range. For example, when the user is a short child or woman, the extra length of the band member 10 may be cut. Further, by making the width of the band member 10 as wide as about 100 mm, it is possible to obtain a good wearing feeling while setting the elastic force of the rubber thread high. Furthermore, the tension | tensile_strength of the band member 10 of this embodiment is not specifically limited, According to a user's muscular strength and exercise ability, it can apply from the thing with a low tension | tensile_strength to a high thing. For example, when the tension of the band member 10 of the present embodiment was measured with a spring balance, the tension was about 2 kg when the band member 10 was elongated by 15%. Assuming children, the elderly, general sports enthusiasts, amateur athletes, and even top athletes as users, the tension of the band member 10 when stretched 100% (twice the original length) is 0. It can be in the range of about 5 kg to 10 kg.

<< Buckle >>
FIG. 2A is an enlarged view of the first annular portion 11 of the training tool 1. As shown in FIG. 2A, both end portions of one band member 10 are routed to the back side of the first annular portion 11, and a male buckle 21 made of a synthetic resin and a female are respectively attached to the both end portions. A buckle 22 is attached.

  When wearing the training tool 1, the user first places the first annular portion 11 around the waist, engages the male buckle 21 and the female buckle 22, and pulls both end portions of the band member 10 with the back hand. Just do it. Thereby, simultaneously with the completion of mounting of the first annular portion 11, the length of the first annular portion 11 can be easily adapted to the size around the waist of the user. Such a first annular portion 11 fits around the waist of the user and serves as a fixing point at the upper end portions of the second and third annular portions 12 and 13.

<<< Rubber Rubber>
As shown in FIG. 2A, the retaining rubbers 30 and 30 of the present embodiment have a configuration in which a plurality of slits are provided radially on a circular rubber plate. The central portion and both end portions of one band member 10 are inserted through the slits of the retaining rubbers 30. Each retaining rubber 30 fixes the band member 10 inserted through the slit by the shrinkage and frictional force of the rubber.

  In the present embodiment, the special retaining rubbers 30 and 30 in which a plurality of slits are provided radially on a circular rubber plate are used. However, the present invention is not limited to this. For example, it is good also as a structure which hold | maintains the cross | intersection part of the band member 10 with cyclic | annular retaining rubber like an O-ring.

<< Reflector Line >>
As shown in FIG. 2A, a band-like reflector line 40 made of a soft clothing reflector is sewn on the front side of the first annular portion 11. Examples of the clothing reflector used as the reflector line 40 include an exposed lens type in which a spherical lens is mounted on the surface of the reflective film, an encapsulated lens type in which a protective film is placed on the spherical lens, and a space between the spherical lens and the protective film. Various types of soft reflective materials for clothing such as a capsule lens type provided with an air layer, a prism lens type using a prism element, and a capsule prism type using a full cube element can be applied. By providing such a reflector line 40 on the front side of the first annular portion 11, it is possible to safely perform night jogging, walking, and other training on the road using the training tool 1.

  Moreover, the reflector line 40 is not only for ensuring the safety of night training. As shown in FIG. 2A, the reflector line 40 of the present embodiment has a length that reaches the second and third annular portions 12 and 13 from the first annular portion 11, and therefore the second and third annular portions. The front and back and the front and back of the band member 10 forming 12 and 13 can be discriminated by the presence or absence of the reflector line 40. Thereby, in the mounting procedure of the training tool 1 shown in FIGS. 3A, 3B and 4A, 4B, which will be described later, based on the presence or absence of the reflector line 40, before and after the band member 10, The second and third annular portions 12 and 13 can be accurately wound around the lower body while grasping the front and back sides.

<<< Strap Strap >>>
As shown in FIG. 2 (b), each of the footrest straps 50, 50 is connected to the second and third annular portions 12, 13 in a chain shape, and with respect to the second and third annular portions 12, 13. Can move freely. Such footrest straps 50 and 50 are formed by wrapping the second and third annular portions 12 and 13 around both legs of the user and then hanging them on the soles of the feet, so that the second and third annular portions 12 and 13 It becomes a fixed point at the lower end.

  In the present embodiment, the back surfaces (or front surfaces) of both ends of the belt-shaped body constituting the leg strap 50 are sewn to face each other. Thereby, the belt-like body of the folded portion 50a of the footrest strap 50 overlaps flatly, and when the footrest strap 50 is hung on the sole of the user, the folded portion 50a comes into surface contact with the user's shin.

  That is, when the front and back surfaces of both ends of the belt-shaped body constituting the footrest strap 50 are joined to each other and joined to form a simple ring, such a footrest 50 is placed on the sole of the user. When folded, the folded portion 50a as shown in FIG. 2 (a) is not formed, and the portion having the thickness of the belt-like body comes into contact with the user's shin. According to the present embodiment, the folded portion 50a is in surface contact with the user's shin, so that the feeling of wearing the footrest strap 50 is good.

  In the present embodiment, the foot strap 50 is provided separately from the second and third annular portions 12 and 13, but the second and third annular portions 12 and 13 are not provided without the foot strap 50. It is good also as a structure which hangs the lower end part of this to a user's sole directly.

<< Training tool installation procedure >>
Next, the mounting procedure of the training tool 1 described above will be described with reference to FIGS. 3A, 3B, 4A, 4B, and 5A to 5C.

As shown in FIG. 3A, when the training tool 1 is worn, the user first places the first annular portion 11 around the waist, and the male buckle 21 is attached. And the female buckle 22 is engaged, and the both ends of the band member 10 are pulled with a back hand. Thereby, the length of the 1st annular part 11 adapts to the size of a user's waist circumference, and mounting | wearing of the 1st annular part 11 is completed.

-Length adjustment of 2nd and 3rd annular part Then, the 2nd and 3rd annular parts 12 and 13 are adjusted to the length suitable for the length of a user's leg. As a measure of the optimal length of the second and third annular portions 12 and 13, for example, as shown in FIG. 3 (a), the footrest straps 50 and 50 are placed on the floor surface when the first annular portion 11 is attached. It should be long enough to be on the side. According to such a method, the second and third annular portions 12 and 13 can be easily adjusted to a length substantially the same as the length of the user's leg, and the second and third annular portions 12 and 13 can be adjusted. When this is wound around the user's leg, an appropriate contraction force for bending the leg can be obtained.

  The above-described length adjustment of the second and third annular portions 12 and 13 may be performed only when the training tool 1 is used for the first time, and the lengths of the second and third annular portions 12 and 13 may be adjusted. Once the adjustment is made, the length adjustment step is omitted, and the first annular portion 11 is simply mounted on the waist, and the second and third annular portions 12 and 13 are wound around both legs, respectively.

-Winding of 2nd and 3rd annular part Then, the 2nd and 3rd annular parts 12 and 13 are wound around a user's both legs, respectively. For example, as shown in FIG. 3B, first, the second and third annular portions 12 and 13 are hooked on the front side and the back side of the pelvis (see FIG. 5C for the back side of the pelvis). . That is, the second annular portion 12 is rotated to the left side while the upper body is hidden from the right side in the drawing. Similarly, the third annular portion 13 is rotated to the right side while the upper body is hidden from the left side in the drawing. Thereby, the second and third annular portions 12 and 13 can be hooked in front of the pelvis.

  Here, when the second and third annular portions 12 and 13 are hooked, the second and third annular portions 12 and 13 are formed using the reflector line 40 shown in FIG. It is good to carry out while grasping the front and back of the band member 10 and the front and back.

  Next, as shown in FIG. 4 (a), the second annular portion 12 is crossed on the front side of the thigh of the left leg in the figure and then crossed on the back side of the knee (for the back side of the knee, FIG. (See (b)). Thereafter, the lower end portion of the second annular portion 12 is positioned on the front side of the shin, and the footrest strap 50 is hung on the sole. Thereby, winding around the left leg of the 2nd annular part 12 is completed.

  Next, the third annular portion 13 is wound around the right leg in the same procedure as described above. That is, as shown in FIG. 4 (b), the third annular portion 13 is made to cross the second annular portion 12 by passing through the front side of the pelvis obliquely. Then, after crossing on the front side of the thigh of the right leg in the figure, crossing is performed on the back side of the knee (see FIG. 5B for the back side of the knee). Thereafter, the lower end portion of the third annular portion 13 is positioned on the front side of the shin, and the footrest strap 50 is hung on the sole. Thereby, the winding of the third annular portion 13 around the left leg is completed, and the mounting on the lower half of the training tool 1 is completed.

<< Shrinking force of training tool >>
Next, the contraction force that the training tool 1 exerts on the user's lower body will be described with reference to FIGS.

  According to the above-described mounting procedure, the training tool 1 mounted on the lower body of the user forms intersections on the front side of the pelvis, the front side of the thigh, and the back side of the knee. These intersections are called a pelvic intersection, a thigh intersection, and a back of the knee, respectively, and are denoted by reference characters CR1, CR2, and CR3 in FIGS.

  5 (a) to 5 (c), the pelvic intersection CR1, the thigh intersection CR2 and the knee back intersection CR3 of the training tool 1 are respectively bent in the directions indicated by solid arrows in the drawing (the lower body joints are bent). (Direction) contraction force is generated, and as a reaction thereof, a load is applied to the movement in the direction indicated by the chain line arrow in the figure (the direction in which the lower body joint is extended). Hereinafter, the effects of the contraction force on the lower body of the user will be described in the order of the pelvic intersection CR1, the thigh intersection CR2, and the knee back intersection CR3.

<<< Pelvic intersection >>>
The pelvic intersection CR1 shown in FIG. 5 (a) extends from the left and right sides of the first annular portion 11 attached around the waist to the front of the pelvis, and its contraction force moves forward (strictly speaking, the user's pelvis). Energize in the forward tilt direction and place it in the middle position (neutral position perpendicular to the floor). The contraction force of the pelvic intersection CR1 has an effect that the trunk of the user rides on the leg and the waist can be smoothly carried during exercise. Further, by urging the user's pelvis forward, there is also an effect that the functions of the complex transverse muscle, the multi-row muscle, the diaphragm, and the pelvic floor muscle group which are deep muscles (inner muscles) of the trunk are promoted.

<<< Thigh intersection >>>
The thigh intersection CR2 shown in FIGS. 5 (a) and 5 (b), together with the pelvic intersection CR1, exerts a contraction force that bends the user's hip joint. The contraction force of the thigh crossing CR2 enables the hip joint to bend without using unnecessary force, and training to bend the leg without using the quadriceps muscle wastefully. Is possible. In addition, the contraction force that flexes the hip joints stresses the hamstrings, which are the muscles that extend the hip joints, and stimulates the hamstrings. Even just standing upright, it becomes possible to train while being conscious of hamstrings. In addition, the muscles of the trunk work together with Hamstrings.

<<<< Knee crossing section >>>>
The knee sole intersection CR3 shown in FIGS. 5B and 5C, together with the thigh intersection CR2, exerts a contraction force that bends the knee joint of the user. The contraction force of the back knee crossing portion CR3 allows the knee joint to bend without using useless force, and training is performed to bend the leg without using the quadriceps. It becomes possible.

<<< Strap Strap >>>
As shown in FIG. 5 (b), the contraction force of the knee crossing portion CR3 is always applied to the foot strap 50, and the cubic bone located near the arch of the sole on which the foot strap 50 is hung. And pull up the scaphoid. As a result, there is an effect that the functions of the posterior tibial muscle and the long peroneal muscle that pull up the sole arch are promoted.

Second Embodiment
As mentioned above, although the training tool 1 of the band form was demonstrated as 1st Embodiment of this invention, this invention is not limited to a band form. For example, as shown in FIG. 6, the training tool 2 of the present invention may be in a wear form.

  In FIG. 6, the training tool 2 in the form of wear is contraction in a direction to bend the joints of the lower body to outerwear or underwear 60 made of a stretchable material that fits legs such as tights, stockings, spats, leggings, trenka, etc. The first, second and third strips 11, 12 and 13 that generate force are sewn to the fabric or knitted into the fibers constituting the fabric.

  Also by the training tool 2 of such a wear form, the same pelvic crossing part CR1, thigh crossing part CR2 and knee back crossing part CR3 as in the first embodiment are formed, and the same effects as in the first embodiment are achieved. It is possible.

<Application of training tools to exercise>
Next, operational effects when the present training tool is applied to lower body exercise will be described with reference to FIGS.

  7 (a) to 7 (c) are schematic diagrams showing a series of operations for efficient running using this training tool, and “Teaching Back” in the book “Soccer Training to Become World Class”. It is based on the schematic diagram. The solid line arrow in the figure indicates the contraction force of the training tool, and the chain line arrow indicates the movement of the user's leg against the contraction force. In addition, the solid line circle in the figure indicates the user's knee, and the black chain ellipse indicates the hamstrings located on the back side of the user's thigh.

<< General effects >>
As shown by solid line arrows in FIGS. 7A to 7C, the lower body of the running user always has contraction force in the direction of bending the joint by the training tool. For this reason, when bending the hip and knee joints, it is sufficient to rely on the contraction force of this training tool, so the hip joint can be bent without using unnecessary force and the leg without using the quadriceps. It is possible to perform training to bend. On the other hand, the contraction force of the training tool constantly applies a load to the hamstrings that extend the hip joint and stimulates the hamstrings, so that the user can run while being aware of the hamstrings. In addition, the contraction force of this training tool always urges the user's pelvis forward to position it in the middle position (neutral position perpendicular to the floor), so that the user's trunk Get on your hips and smooth your waist during exercise.

<< First Travel Step >>
First, as shown in FIG. 7A, the user applies the hamstrings against the contraction force of the training tool, and stretches the knee of the left foot to land. As a result, the user's trunk gets on the legs and the waist can be carried smoothly. At this time, the contraction force of the training tool urges the user's pelvis forward to support the user's trunk on the leg. On the other hand, the user strongly swings the right leg forward using the iliopsoas muscle and the contraction force of the training tool without putting unnecessary force on the right leg.

<< Second travel step >>
Next, as shown in FIG. 7 (b), the user receives a repulsive force from the ground with the left leg extended using the hamstrings in the running step of FIG. 7 (a), and this repulsive force is forwarded. Use it as a driving force. On the other hand, the user carries the right leg further forward using the iliopsoas muscle and the contraction force of the training tool without putting unnecessary force on the right leg. Thus, by using this training tool, hamstrings can be actively used and useless use of the quadriceps can be eliminated, so that the running speed and cut are maintained.

<< Third Travel Step >>
Finally, as shown in FIG. 7C, the user's left leg is swung backward and the right leg is swung forward, and the soles of both legs are separated from the ground. In both steps of FIGS. 7A and 7B, the user does not land by bending the knee or pushing the ground by stretching the knee. Through FIGS. 7A to 7C, The waist position is stable and a high center of gravity is maintained.

<< Efficient teaching of lower body exercise >>
As described above, by using this training tool, it is possible to eliminate unnecessary use of the quadriceps muscles and teach the body of efficient lower-body exercise using hamstrings. In other words, by wearing this training tool, daily walking and running, or simply running daily life, you can train hamstrings and suppress the use of quadriceps. This makes it possible for the body to learn an efficient lower body exercise. And if you let your body learn efficient exercises for the lower body, when you don't wear this training tool, you will be able to use your lower body and move your lower body efficiently. The body can feel the sensation of lightening.

<Other changes>
The training tool of the present invention is not limited to the first and second embodiments described above.
