Description

  The present invention relates to an exercise aid, an exercise aid set, and an exercise method capable of obtaining a preventive and ameliorating effect of dementia.

  Currently, the number of patients with dementia is 4.62 million, and it is said that it is even 10 million including the number of patients with early dementia, which is the previous stage of dementia. And since the number is expected to increase in the future, the prevention of dementia is the latest issue. There are many known methods for preventing dementia, and among them, it is generally known that exercise is effective, and its effectiveness has been proved. Recently, it has also been demonstrated that hippocampal neurons responsible for memory, which are thought to not regenerate once lost, are regenerated by exercise.

  For prevention and amelioration of dementia, it is not enough to simply exercise, but it is effective to continuously carry out exercises in four areas of aerobic exercise, muscle strengthening, balance training and flexibility training in a well-balanced manner It is known to be. Aerobic exercise is the basis of exercise, reducing visceral fat and improving major cardiovascular risks such as insulin resistance, high blood pressure, hyperglycemia, and serum lipid abnormalities. Muscle strengthening is also important in terms of maintaining muscle strength for daily life. And training balance skills through balance training is also important to reduce the risk of falling. It is also possible to prevent dementia indirectly from the fact that the decline in daily living activities caused by falls induces dementia. However, in order to train balance ability, it is necessary to do exercise that stimulates the cerebellum as well as regular exercise. In addition, muscle and joint flexibility training is also required to perform these series of exercises smoothly.

  By the way, in recent years, a health device for stretching, massaging or exercising a toe, a foot sole, an arch, a lower thigh, and the like is known. In Patent Document 1, for the purpose of restoring the soundness of the sole arch, the footboard slidably formed with the footboard on which the footrest is formed, and the inclination angle of the footrest is adjusted A stretchboard has been proposed which comprises a vent board for the purpose of forming a toe bar near the top of the step.

  Hereinafter, embodiments of the present invention will be described using drawings and the like, but the present invention is not limited to the following embodiments as long as it does not deviate from the spirit of the present invention.

  FIG. 1 is an example of a top perspective view of an exercise aid corresponding to at least one of the embodiments of the present invention. As shown in FIG. 1, the exercise assisting tool 1 comprises a pair of main bodies 2. The user places the left foot and the right foot on the upper surface of the left main body 2a and the right main body 2b, stands up, and performs various exercises described later. Hereinafter, in the present embodiment, the left main body 2a will be described. The right main body 2b has a three-dimensional shape that is symmetrical with the left main body 2a, and thus the description thereof is omitted.

  FIG. 2 is an example of a top view of an exercise aid corresponding to at least one of the embodiments of the present invention. FIG. 3 is an example of a side view of an exercise aid corresponding to at least one of the embodiments of the present invention. The left main body 2 a includes a base portion 3, an inclined portion 4 and a protrusion 5. The inclined portion 4 and the projecting portion 5 are preferably configured using an elastic material. The base portion 3 may also be made of an elastic material. Although it does not specifically limit as an elastic material, For example, it is preferable that it is a material which has elasticity and moderate resilience. Furthermore, it is more preferable to have the lightness so as to be easy to carry. From the viewpoint of elasticity, resilience, and lightness, for example, using an elastic resin material such as EVA (ethylene vinyl acetate copolymer), PU (polyurethane), EPP (foamed polypropylene), EPE (foamed polyethylene), etc. Is preferred. These elastic materials are preferably porous. Note that these materials may be used alone or in combination of two or more. The base portion 3, the sloped portion 4 and the projecting portion 5 may be made of different materials, or may be made of the same material. Moreover, it is preferable that the base part 3 is comprised with a material harder than the inclination part 4 (elasticity is low).

  As shown in FIGS. 1 to 3, the base portion 3 is in the shape of a right triangular prism having a base of a right triangle. Specifically, both bottom surfaces of the right-angled triangular prism are inclined in directions respectively perpendicular to the horizontal direction, and surfaces corresponding to both bottom surfaces of the right-angled triangular prism are the left side surface 6 and the right side surface of the main body 2a. It is eggplant. Then, the surface corresponding to the side including the long side of the bottom of the right triangular prism is the bottom, and the surface corresponding to the side including the oblique is the inclined surface facing upward.

  A sheet-like inclined portion 4 is stacked on the inclined surface of the base portion 3. The inclined portion 4 is made of an elastic material and has a predetermined substantially uniform thickness. The shape of the inclined portion 4 changes when the user (for example, an adult male with a weight of 60 kg and a foot size of 25 cm) rides on at normal temperature and normal pressure (for example, 23 degrees and 1 atm). If the person gets down, it is preferable to return to the original shape. Furthermore, it is preferable that the inclined portion 4 be more flexible than the base portion 3. Thus, by providing the flexible inclined portion 4 on the base portion 3 whose upper surface is inclined, when the user gets on the main body 2a, the foot becomes unstable. Therefore, in order to keep the user standing on the main body 2a, it is necessary to always keep balance, and it is possible to effectively strengthen the balance ability only by standing on the main body 2a. In addition, since the base portion 3 which is harder than the inclined portion 4 is present under the inclined portion 4, the user can exercise on the main body 2a even in an unstable state.

  The thickness of the inclined portion 4 is preferably 5 mm or more, more preferably 7 mm or more, and still more preferably 9 mm or more. The thickness of the inclined portion 4 is preferably 20 mm or less, more preferably 15 mm or less, and still more preferably 12 mm or less. If the thickness of the inclined portion 4 is thinner than 5 mm, the feet become stable, and it tends to be difficult to effectively strengthen the balance ability. If the thickness of the inclined portion 4 is greater than 20 mm, the foot becomes too unstable and the user tends to lose balance and to fall easily. On the other hand, when the thickness of the inclined portion 4 is in the range of 5 mm to 20 mm, when the user gets on the top, the posture becomes unstable, but the possibility of falling is maintained while the state is low. Can exercise.

  The inclination angle of the surface of the sloped surface and the inclined portion 4 with respect to the bottom surface of the base portion 3 is preferably 3 degrees or more, more preferably 5 degrees or more, and still more preferably 6.5 degrees or more . The inclination angle of the surface of the inclined surface and the inclined portion 4 is preferably 15 degrees or less, more preferably 12 degrees or less, and still more preferably 8 degrees or less. The exercise assisting device 1 of the present invention is used by the user with the foot placed on the surface of the inclined portion 4 with the toe facing the inclined top side. Therefore, when the inclination angle is larger than 15 degrees, when standing with the foot on the surface of the inclined portion 4, there is a tendency that the possibility of falling back increases. On the other hand, when the inclination angle is smaller than 3 degrees, the feet become stable, and it tends to be difficult to effectively strengthen the balance ability. In the present embodiment, the surface of the inclined portion 4 is the inclined surface of the exercise assisting tool 1.

  The ratio (Ha / La1) of the height Ha from the bottom to the surface of the slope 4 and the longitudinal length La1 of the bottom at the slope top side end portion is preferably 0.11 / 1 or more It is more preferably 0.14 / 1 or more, still more preferably 0.15 / 1 or more.

When Ha / La1 is smaller than 0.11 / 1, the inclination is reduced, and it tends to be difficult to effectively strengthen the balance ability. When Ha / La1 is larger than 0.25 / 1, the inclination tends to be large and to fall easily. On the other hand, when Ha / La1 is 0.11 / 1 to 0.25 / 1, it is possible to effectively strengthen the balance ability in a state where the user is less likely to fall.

  The ratio (Wa / La1) of the width Wa of the bottom to the length La1 of the bottom in the longitudinal direction is preferably 0.44 / 1 or more, and is 0.55 / 1 or more. Is more preferable, and 0.6 or more is more preferable. Wa / La1 is preferably 1/1 or less, more preferably 0.81 / 1 or less, and still more preferably 0.74 / 1 or less. When Wa / La1 is smaller than 0.44 / 1 or larger than 1/1, it is difficult to determine the position on which the foot is placed on the main body 2, and it tends to be difficult to obtain an appropriate exercise effect. On the other hand, when Wa / La1 is 0.44 / 1 to 1/1, the user can effectively strengthen the balance ability in a state where the possibility of falling is low.

  The length of La1 is preferably 240 mm or more, more preferably 270 mm or more, and still more preferably 285 mm or more. The length of La1 is preferably 360 mm or less, more preferably 330 mm or less, and still more preferably 315 mm or less. In addition, the length of Wa is preferably about 160 mm or more, more preferably 180 mm or more, and more preferably 190 mm or more, since it is approximately the length of two foot width of a Japanese adult male.

Lb / Wb is preferably 0.98 / 1 or less, more preferably 0.76 / 1 or less, and still more preferably 0.67 / 1 or less. When the ratio of Hb / Lb and Lb / Wb is both out of the above range, the curvature of the curved surface 8 is large, the toes may be too much curled and may feel pain, or conversely, the curvature may be too small and the toes may be warped. It does not return, and it tends to be difficult to obtain the stretch effect. When the ratio Hb / Lb is within the above range, the curve of the curved surface 8 has a curvature such that the toe does not feel pain and an appropriate stretch effect can be obtained. In addition, when the ratio of Hb / Lb to Lb / Wb is both within the above range, the curve of the curved surface 8 has a curvature close to the curve of the arch, and the curved surface 8 and the arch easily contact the entire surface. , The arch stretch effect is high.

Among Hb, Lb or Wb, two are preferably in the above-mentioned numerical range, and it is more preferable that all three are in the above-mentioned numerical range.

  In particular, when the height Hb is 15 mm to 45 mm, when the toe is placed on the protrusion 5, the muscles and ligaments of the sole of the foot can be appropriately stretched without the user feeling a strong pain. When the height Hb is higher than 45 mm, when the user stands on the main body 2a, the toes of the toes tend to be too warped, making it difficult to feel pain or maintain an upright posture. On the other hand, when the height Hb is less than 15 mm, the amount of extension of the muscles of the soles of the foot and the like tends to be small, which tends to make it difficult to obtain a sufficient stretch effect.

  Furthermore, the ratio (Wb / Wa) of the length Wb of the side where the curved surface 8 of the protrusion 5 is in contact with the inclined portion 4 and the length Wa of the base portion 3 in the lateral direction is 0.33 / 1 or more Is preferably 0.41 / 1 or more, more preferably 0.45 / 1 or more. Further, Wb / Wa is preferably 0.75 / 1 or less, more preferably 0.61 / 1 or less, and still more preferably 0.55 / 1 or less. The ratio (Lb / La2) of the length Lb of the side where the side surface of the protrusion 5 is in contact with the slope 4 to the length La2 in the longitudinal direction of the slope 4 is preferably 0.14 / 1 or more.

Further, Lb / La2 is preferably 0.33 / 1 or less, more preferably 0.25 / 1 or less, and still more preferably 0.22 / 1 or less.

  Length Lc from the slope top side end of slope 4 to the side closer to slope top among sides where curved surface 8 and slope 4 are in contact, and length La2 in the longitudinal direction of slope 4 The ratio (Lc / La2) is preferably 0.11 / 1 or more, more preferably 0.14 / 1 or more, and still more preferably 0.15 / 1 or more. Lc / La2 is preferably 0.25 / 1 or less, more preferably 0.20 / 1 or less, and still more preferably 0.19 / 1 or less. Further, the ratio (Wc / Wa) of the length Wc from the end on the right side of the inclined portion 4 to the right side of the protrusion 5 and the length Wa in the short direction of the base portion 3 is 0.07 / 1 or more is preferable, 0.08 / 1 or more is more preferable, and 0.09 / 1 or more is more preferable. Wc / Wa is preferably 0.15 / 1 or less, more preferably 0.12 / 1 or less, and still more preferably 0.11 / 1 or less. When any ratio of Wb / Wa, Lb / La2, Lc / La2 or Wc / Wa is within the above range, the user is appropriately loaded with safety secured and exercised. You can get the effect.

The length Wc is preferably 24 mm or less, more preferably 22 mm or less, and still more preferably 21 mm or less.

  When any one of La2, Lc or Wc is within the above-mentioned numerical range, the protrusion 5 has the shape of a curve of the user's arch when the exercise assisting tool 1 of the present invention is used in the manner of green bamboo stepping. And it becomes a shape that matches the width of the arch and can stretch the sole more effectively. It is preferable that any two of La2, Lc or Wc be within the above numerical range, and it is more preferable that all three be within the above numerical range. When the user puts the foot on the main body 2a, if it is out of the above numerical range, an appropriate repulsive force can not be obtained from the main body 2a, or an appropriate portion of the sole of the foot is hard to hit the projection 5 As a result, it becomes difficult to obtain the effect of exercise by using the exercise assisting device 1.

  It is preferable that the left side surface 7 of the protrusion 5 be separated from the left end of the inclined portion 4 by a predetermined length. The space provided on the left side of the left side surface 7 of the inclined portion 4 makes it easy for the user to place his / her foot at a position where the protrusion 5 contacts only the arch portion of the user.

  The protruding portion 5 may have the same hardness as the inclined portion 4 or may be softer than the inclined portion 4. In addition, the protrusion 5 may be fixed to the surface of the slope 4 with an adhesive or the like, which is made as a member separate from the slope 4, or the protrusion 5 and the slope 4 may be integrated. It may be molded into

  Note that the size of the length, height, and the like of the main body 2a in the present embodiment may be changed within the range in which each ratio described above is held. For example, a smaller size may be used for women and children, or a larger size may be used for Westerners who are larger than Japanese.

  In the present embodiment, although the example in which the shape of the base portion 3 is a right triangle is described as an example, if the shape of the base portion 3 has a surface inclined with respect to a horizontal plane when placed on a plane Not limited to this. For example, it may be in the shape of a right trapezoidal trapezoid having a base of a right trapezoidal shape. Specifically, both bottom surfaces of the right-angled trapezoidal column are inclined in directions respectively perpendicular to the horizontal direction, and a surface corresponding to a plane having sides including both right-angled portions of the bottom surface is the bottom surface. Also good.

  In the present embodiment, the shape of the protruding portion 5 is described as an example of a shape obtained by cutting a cylinder in the vertical direction, but the bottom of the cylinder may not be a perfect circle but an elliptical shape. For example, if the shape of the protrusion 5 is a cylinder whose bottom is an elliptical cylinder and is cut by a plane parallel to the major axis of the ellipse, the curved surface 8 of the protrusion 5 draws a gentle curve, and more arched Fit to the arch and it is easy to obtain the effect of exercising using the exercise aid 1.

  The usage method of the exercise assistance tool 1 in this Embodiment is demonstrated. The order of performing exercises described below is an example, and the order of each exercise may be switched. FIG. 4 is an example of a schematic view of a state where a foot is placed on an exercise support, as viewed from the side, corresponding to at least one of the embodiments of the present invention. The user places the pair of main bodies 2 on a horizontal surface in a direction in which the inclined top is located on the back side as viewed from the user. Then, the left foot and the right foot are placed on each of the left main body 2a and the right main body 2b, and the posture is maintained. In the state where the user places the foot 9, the user places the foot in such a position that the toe contacts the user side of the protrusion 5. Since the upper surface of the main body 2a is inclined so that the toe is on top, for example, with the foot placed on the inclined surface so that the toe contacts the user side of the projection 5, or With the foot placed on the projecting portion 5 so as to be positioned on the inclined top side with respect to the projecting portion 5, the muscles of the rear lower leg will be stretched only by the user standing up. Furthermore, since the fingertips of the foot rest on the curved surface 8 of the protrusion 5, the muscles and ligaments of the sole of the foot are also extended. Further, since the portion on which the foot of the main body 2 is placed is the inclined portion 4 softer than the base portion 3, when standing on the main body 2, the posture of the user becomes unstable. Therefore, the user must always keep balance in order to maintain the posture. Thus, the user can perform flexibility training and balance training only by standing on the main body 2 and maintaining its posture. Here, the “user side of the protrusion” is, for example, a plane parallel to the left-right direction of the inclined surface, and the protrusion 5 is divided into two regions by a plane including a straight line representing Hb. In this case, it is an area located on the side of the heel of the slope. Specifically, the “user side of the protrusion” refers to the area indicated by hatching in FIG. 4. Further, “the slope top side than the protrusion” is, for example, a plane parallel to the left and right direction of the slope and dividing the protrusion 5 into two regions by a plane including a straight line representing Hb. In this case, it is an area located on the top side of the slope. Specifically, “the slope top side with respect to the protrusion” refers to a region other than the hatched region of the protrusion 5 in FIG. 4.

  With the foot placed on the main body 2 in such a position that the toe of the protrusion 5 is on the user side of the protrusion 5, the user lifts and lowers the heel and performs the stepping motion on the spot. The stepping exercise is an aerobic exercise, and the upper surface of the main body 2 has a predetermined inclination angle, and therefore, the user's muscles are more heavily loaded than when performing a heel raising and lowering exercise on a normal horizontal surface. By performing this exercise, the user can train the muscles on the lower thigh side. In other words, it is possible to strengthen the muscle. In addition, since the upper surface of the main body 2 is soft and the posture is not stable, the user must always keep balance, which also results in balance training. Furthermore, since the fingertips are in a state of being placed on the protrusion 5, muscles and ligaments such as the sole of the foot are stretched. Thus, the user can perform aerobic exercise, muscle strengthening, flexibility training, and balance training by performing stepping motion on the main body 2 in situ.

  The user can also exercise to move the position of the knee, such as bending and stretching, while standing upright on the upper surface of the main body 2, instead of stepping on the spot. For example, the leg can be placed on the inclined surface so that the toe contacts the user side of the protrusion 5 and the bending and stretching movement can be performed in a state where the heel is in contact with the inclined surface. Bending and stretching exercises are generally known as exercises that have the effect of stretching the rear lower thigh, but by performing bending and stretching exercises with the toe positioned above the heel, they are near the leg shins You can get the effect of flexibility training, which increases the flexibility of muscles and ankle joints. And since it carries out on the upper surface of the unstable main part 2, it also serves as balance training. Thus, the user can perform flexibility training and balance training by performing bending and stretching exercises on the main body 2.

  Next, the user stands on the main body 2 for about one minute. FIG. 5 is an example of a schematic view of a state where a foot is placed on an exercise support, as viewed from the side, corresponding to at least one of the embodiments of the present invention. FIG. 6 is an example of a schematic view of the state corresponding to FIG. 5 corresponding to at least one of the embodiments of the present invention as viewed from above. The user places the foot on the protrusion 5 so that the toe is located closer to the slope top than the protrusion 5. Furthermore, as shown in FIG. 5 and FIG. 6, the user places the foot at a position where the little finger of the left foot 9 is located beside the left side surface 7 of the protrusion 5. And the left side surface 7 are grasped so as to be sandwiched between the little finger and the ring finger. In this state, one foot standing for about one minute is performed on the main body 2. One foot standing for one minute corresponds to the same basal metabolic rate as walking for 50 minutes, and the same effect as performing aerobic exercise can be obtained. Also, because the foot is in an unstable state, the user needs to keep balance more carefully than when standing with one leg normally. In this way, the user can stand on the main body 2 with one foot to obtain the same effect as performing aerobic exercise and can perform balance training.

  By performing the exercise described above, it is possible to perform well-balanced exercise in four areas effective for preventing and improving dementia, that is, aerobic exercise, muscle strengthening, balance training, and flexibility training. And since the above-mentioned exercise can obtain an effect even if it carries out all for a short time, a user can exercise continuously every day.

  In addition to the above-described three exercises, for example, even if the following exercises are performed in combination, the exercises in the four regions can be performed efficiently.

  As the projection 5 hits the arch, it is possible to perform the stepping exercise in the same manner as the green bamboo stepping. Stepping exercise is an aerobic exercise and has the effect of strengthening the muscles used when moving the foot up and down. In addition, since the foot is in an unstable state, the user needs to make balance in order to stabilize the posture. In addition, the effect of stretching exercise can be obtained to loosen the muscles and ligaments around the arch. Thus, the user can perform aerobic exercise, muscle strengthening, balance training, and flexibility training by performing stepping motion on the main body 2 in place.

  In addition to effectively performing exercise in the four areas, the above exercise has the effect of improving the balance of the plantar ligament, muscles and bones, and correcting the flexor foot. In addition, by opening the knees and pelvis, the posture is improved, and as a result, it is possible to prevent falling. In addition, although the above-mentioned exercise can be sufficiently effective if it performs about 1 minute and foot stepping exercise about 30 times at that time, elderly people etc. can obtain an effect even if it is a short time or a small number of times. Can.

  The exercise assisting device 1 according to the present embodiment is divided into two main bodies of a left main body 2a on which the left foot is placed and a right main body 2b on which the right foot is placed. Therefore, by adjusting the distance between the two bodies, it is possible to exercise in a state suitable for the foot width of the user. Moreover, there is also an advantage that carrying is convenient because the left and right bodies are independent in compact size.

  In the present embodiment, as an example of the exercise assisting tool 1, it has been described using two main bodies separated into the left main body 2 a for the left foot and the right main body 2 b for the right foot. The tool 1 may be configured integrally with the left main body 2 a and the right main body 2 b. That is, the width of the base portion 3 and the inclined portion 4 may be increased so that both feet can be simultaneously placed on one main body. In the case of a shape in which both feet can be placed on one main body, the length Wb of the protrusion 5 may be increased to make the protrusion 5 as one, or use as a guide for the position where the left and right legs are to be placed. For this purpose, the projecting portion 5 may be divided at an intermediate position in the width direction and separately provided for the left foot and the right foot.

  As described above, using the exercise assisting device 1 of the present invention, it is possible to efficiently perform the exercise in four areas of aerobic exercise, muscle strengthening, balance training and flexibility training in a short time, and dementia We can plan prevention, improvement.

  Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited at all by these examples.

  In the following examples, the effects obtained by the exercise method were evaluated by the mini mental state test (MMSE test).

(Mini Mental State Examination (MMSE Examination))
The mini mental state test is a set of questions developed for the diagnosis of dementia, and consists of 11 questions with a full score of 30. It covers orientation, memory, computing skills, verbal skills, graphic skills, etc. Diagnosis is normal at 27 points or more, diagnosis of early dementia (mild dementia) at 22 to 26 points, and diagnosis of dementia at 21 points or less.

(Exercise aid)
As the exercise aid, the left main body 2a and the right main body 2b for the right foot were separated. The left main body 2a is 50 mm for Ha, 300 mm for La1, 300 mm for La2, 200 mm for Wa, 22 mm for Hb, 60 mm for Lb, 60 mm for Wb, 100 mm for Lb, 50 mm for Lc, 20 mm for Wc, 10 mm for inclined surface thickness, and inclination angle The base 3, the slope 4 and the protrusion 5 are made of EVA (ethylene vinyl acetate copolymer). The right side main body 2b has a symmetrical shape with the left side main body 2a, and is made of the same material as the left side main body 2a.

  In the following example, 20 patients with early-stage dementia (patients who scored 22 to 26 in the mini mental state test) were used as subjects and three times a week for 3 months using the above-mentioned exercise aids. The following exercises were carried out.

  First, the subject stands on the exercise aid for 1 minute. At this time, in a state where the subject, ie, the user places the left foot and the right foot on each of the left main body 2a and the right main body 2b, the fingertip portion of the foot is placed on the user side of the protrusion 5. Next, have the subject perform stepping on the exercise aid for one minute. Then, the subject moves his or her foot so that the toe is positioned closer to the top of the slope than the protrusion 5, and causes the subject to stand for one minute on the exercise aid. Then, after 3 months, a mini mental state test was conducted. The results of the test are shown in Table 1.

  From the above results, it can be seen that 90% (18 out of 20) of the subjects had the effect of maintaining and improving dementia. That is, when exercise is performed using the exercise assisting device 1 of this embodiment, it can be said that it is significant for the prevention and improvement of early dementia. This result shows that, by using the exercise assisting device 1 of the present invention, the effects of the four areas of exercise of aerobic exercise, muscle strengthening, balance training and flexibility training can be obtained in a well-balanced manner.
