Description

  The present invention relates to an auxiliary tool for strengthening muscle strength of the lower abdomen.

  Humans tend to accumulate fat with aging because their metabolism decreases with aging. In particular, the lower abdomen is a part where it is difficult to train muscles and is a part where fat is easily attached.

  In order to reduce fat on the lower abdomen, not only aerobic exercise, but also abdominal strength training is required. Examples of abdominal strength training include exercises that raise the upper body with the hips facing the ground, and methods of bending and stretching the legs with the hips on the ground and the back away from the ground. However, with this strength training method, it is difficult to maintain balance simply by bending and stretching the foot several times if not used, there is a risk that the abdominal strength training cannot be performed correctly, and the waist and the like are damaged.

  Other lower abdominal muscle strength training methods include a method to increase muscle strength by breathing against a thin tube as in Patent Document 1, but the lower abdominal exercise is not large, so it takes a short time. It is difficult to increase the effect.

[Configuration of lower abdominal strength strengthening aid]
First, the configuration of the lower abdominal muscle strength reinforcing aid 11 will be described. As shown in FIG. 1, the lower abdominal muscle strength strengthening auxiliary tool 11 includes a stretchable 12 string provided with foot fixing members 13, 13 at both ends, and a neck pad 14 provided near the center of the stretchable string 12. .

  The elastic string 12 has a diameter of about 3 to 5 cm and a length of about 50 cm to 1 m. The elastic string 12 can be stretched about 1.5 to 2 times in the length direction of the elastic string 12 by a normal human force. Become. The stretchable string 12 may be covered with a protective material or the like from the viewpoint of decoration and safety.

  The foot fixing members 13, 13 are for fixing the lower abdominal muscle strength reinforcing aid 11 to the user's foot, and are connected to both ends of the stretchable string 12, respectively. In order to extend / contract the elastic string 12 using the legs, the sole of the foot is placed on the foot fixing members 13, 13, and the elastic strap 13 is extended by pushing the foot fixing members 13, 13 against the sole of the foot. Can be expanded and contracted. Therefore, it is preferable that the foot fixing members 13 and 13 have a plate-like member for arranging the soles of the feet.

  If the foot fixing members 13 and 13 are detached from the foot when the foot is extended, the foot fixing members 13 and 13 collide with the user's face and body due to the elastic force of the stretchable string 12. It is a danger. Therefore, the foot fixing members 13, 13 are preferably provided with a fixing member that can be firmly fixed to the foot, for example, a hook-and-loop fastener, and a mechanism that can be fixed to the foot.

  The neck rest 14 is provided in the vicinity of the center of the length of the telescopic string 12. The neck pad 14 is arranged behind the wearer's neck, and disperses the pressure of the stretchable string 12 applied to the neck by stretching the foot.

  Next, the lower abdominal muscle strength strengthening assisting tool 21 shown in FIG. 2 will be described. The lower abdominal strength strengthening assisting tool 21 includes an elastic cord 22, leg fixing members 23 provided at both ends thereof, and a neck rest 24, like the lower abdominal strengthening assisting tool 11. The lower abdominal muscle strength reinforcing aid 21 further includes arm stretchable straps 26 and grips 25, 25 provided at both ends thereof.

  The elastic cord 26 for the arm is bundled with the neck strap 24 together with the elastic cord 22. Further, a neck rest 24 is disposed near the center of the arm stretchable strap 26. The material of the elastic cord 26 for the arm may be the same as that of the elastic cord 22, and the length is about 40 cm to 60 cm, but the length can be adjusted according to the length of the user's arm. You may do it.
