<Function>
In the above configuration, a case where the user exercises (including stretching) using the exercise assisting device 10 will be described.

  FIG.4 and FIG.5 is explanatory drawing for demonstrating an effect | action of the exercise assistance tool 10 which concerns on this embodiment. Specifically, FIG. 4 is a view showing a state in which the user P is seated on the seating surface 121 when the exercise assisting device 10 is used. FIGS. 5A to 5C are diagrams showing the flow of exercise for training the trunk using the exercise assisting device 10.

  As shown in FIG. 4, when the user P exercises using the exercise assisting device 10, the exercise assisting device 10 is placed on the floor surface 200 or a pedestal 202 provided on the floor surface 200, The exercise assisting device 10 is placed. Then, the user P rotates the seat 12 so that the lower end of the seat 12 in one direction is on the front side, in other words, the front is low, and sits on the seat surface 121. At this time, since the seat surface 121 is inclined, the pelvis of the user P naturally stands, the upper body can stand upright, and the body axis O2 can be made into one linear axis.

  Next, as shown in FIG. 5 (A), the user P brings both hands together or holds the other hand with one hand.

  Then, as shown in FIG. 5B, the user P uses the rotation of the seat portion 12 to rotate the lower body and twists the upper body in the direction opposite to the rotation direction.

  Subsequently, after the user P returns from the state shown in FIG. 5B to the state shown in FIG. 5A, as shown in FIG. Is rotated in the direction opposite to the rotation direction shown in FIG. 5A, and the upper body is twisted in the direction opposite to the rotation direction.

  The user P repeats the exercise shown in FIGS. 5 (A) to 5 (C). In addition, as shown in FIG. 5 (B) and FIG. 5 (C), when twisting the upper body, draw both elbows round along the body alternately, and put Tanda (built-in) in the left and right hip bones. It is preferable to twist.

As described above, according to the present embodiment, since the seat surface 121 is inclined during the exercise shown in FIGS. 5A to 5C, the trunk of the user P is used at an appropriate exercise intensity, It is an exercise of the trunk and can be trained.
Here, since the seat surface 121 has a short length L1 in one direction, in other words, a short length in the front-rear direction when the user P is seated, the user P is in an unstable state. In this unstable state, the user P exercises to maintain balance by consciously recognizing the trunk so as not to fall down, so the trunk is tensed and the trunk is effectively forged. be able to. In particular, in the exercise using the exercise assisting device 10 as described above, among the trunk, it is possible to effectively train the greater lumbar muscle 300 and the iliac muscle 301 as shown in FIG. 6 (A). Further, among the trunk, as shown in FIG. 6 (B), the internal oblique muscle 304 and the transverse abdominal muscle 306 located inside the external oblique muscle 302 can also be effectively trained. In this way, if you can train the trunk effectively, you can create a firm, unblurred body core, learn accurate axis rotation, foam, hip movement, and adjust the intestinal environment. Can be (preventing deterioration of the intestinal environment). In addition, it is possible to prevent the user P from being obese or bent back.
Further, since the length L2 in the other direction in the seat surface 121 is long, the buttocks can be supported in the left-right direction.

  Further, according to the present embodiment, the length L1 of the seat 121 in one direction is half or less of the length L2 in the other direction of the seat 121, for example, 30 mm or more and 70 mm or less. The user P can be given a sense of instability before and after sitting. If this sense of insecurity is given, the user P comes to exercise with a more conscious awareness of the trunk to maintain balance, so that the trunk can be trained more effectively.

  Further, according to the present embodiment, since the seat surface 121 is curved so that the central portion protrudes downward when viewed from one direction, the buttocks of the user P can be fitted to the seat surface. it can. Further, due to this curvature, the rotational axis O1 passes through the central portion, and when sitting on the seat surface 121, the center of gravity gathers in the anus of the buttocks, and the body axis O1 coincides with the rotational axis O1 of the seat 12 (see FIG. 4) .), The rotational movement of the user P can be facilitated.

  Further, according to the present embodiment, since the inclination angle of the seat surface 121 is more than 15 degrees and less than 25 degrees, the trunk can be trained more effectively.

Experimental Example 1
As Experimental Example 1, in the exercise assisting device 10 according to the above-described embodiment, an experiment was performed to evaluate the relationship between the inclination angle of the seat surface 121 and the effect of training the trunk. The experimental results of Experimental Example 1 are shown in Table 1 below. The evaluation was performed in the order of "A", "B", "C", and "D" in descending order.

  As shown in Table 1, when the inclination angle of the seat surface 121 was 0 degree, the user P's pelvis went to sleep, the trunk was not used, and the evaluation was the lowest "D". In addition, when the inclination angle of the seat surface 121 was 5 degrees or 10 degrees, although the pelvis slept slightly, the trunk was used, and the trunk could be effectively forged. In addition, when the inclination angle of the seat surface 121 is 16 degrees, 20 degrees or 24 degrees, the pelvis naturally stands, and the trunk can be trained more effectively. Furthermore, when the inclination angle of the seating surface 121 is 25 degrees, 30 degrees or 35 degrees, the pelvis stands up too much, making it difficult to move the hip joint etc. or to rotate about the body axis O2 In some cases, the trunk was able to be trained more effectively than when the inclination angle was 0 degrees.

  From the above, the inclination angle of the seat surface 121 is more than 0 degrees, preferably 5 degrees or more and 40 degrees or less, more preferably 10 degrees or more and 35 degrees or less, and more than 15 degrees or less than 25 degrees It turned out that this is even more preferable.

<Experimental Example 2>
As Experiment 2, in the exercise assisting device 10 according to the above-described embodiment, an experiment was performed to evaluate the relationship between the length L1 of the seat surface 121 and the effect of training the trunk. The experimental results of this Experimental Example 2 are shown in Table 2 below. The evaluation was performed in the order of "A", "B", "C", and "D" in descending order.

  As shown in Table 2, it was found that the evaluation becomes better as the length L1 becomes shorter to 80 mm, 70 mm, 60 mm..., That is, the trunk can be trained more effectively. However, when it became less than 40 mm, evaluation became bad and it turned out that evaluation becomes still worse as it becomes less than 10 mm. This is because it is difficult for the user P to sit on such a seating surface 121 and it is difficult to exercise.

  From the above, the length L1 of the seat surface 121 is preferably 70 mm or less, and more preferably 60 mm or less. The length L1 of the seat surface 121 is preferably 20 mm or more, and more preferably 40 mm or more.

<Modification>
The present invention is not limited to the above specific example. That is, to the above specific examples, those skilled in the art may appropriately modify the design as long as the features of the present invention are included in the scope of the present invention.
