Description

  The present invention relates to a physical strength enhancing device for use in a bathtub for the purpose of enhancing physical strength in addition to abdominal muscles and adductor muscles, utilizing the weight and buoyancy of hot water during bathing.

Conventionally, as a training tool of this type, for example, as described in the patent publication “JP-A-9-140828”, a foot is placed on a footrest portion of an abdominal muscle base or a foot is placed on a belt-like place to be fixed. Devices that mainly exercise abdominal muscles by tilting or raising the upper body backward are known.
Japanese Laid-Open Patent Publication No. 9-140828

  However, many of these instruments are large and easy to install in a room, and take time to exercise in daily life, and it is difficult to continue until the effect appears.

  For those with back pain, it is effective to train the abdominal muscles to overcome it, but if you do not, you will worsen the back pain while training the abdominal muscles. In addition, as the body ages, the abdomen squeezes out as the abdominal muscles weaken, making it difficult to maintain the body shape. In addition, the risk of adult disease increases and consideration for health is also necessary.

  As described above, healthy people who have been feeling physically weak or lacking exercise in the adult illness reserve army, who are concerned about their health to recover their health and maintain their physical fitness, have been focusing on the abdomen and lower body during daily bathing. It aims at providing the physical strength augmentation instrument which can be trained.

  The present invention can adjust the buoyancy and moderately adjust the weight of the physical strength augmentation device used in the bathtub by appropriately putting hot water from the bathtub into the physical strength augmentation device used in the bathtub, and load depending on the age and physical strength of the user. You can change the exercise.

  The present invention makes it possible to continue exercising for a long period of time by using it in a bathtub during daily bathing, and can obtain good results. Adjusts the load during exercise by adjusting the water injection to the physical strength enhancing equipment used in the bathtub to cope with differences in the physical strength and state of the user, increase in blood flow due to bathing, increase the blood flow, relax muscles, and water pressure By obtaining a synergistic effect of the pressure load on the body, it is possible to efficiently strengthen muscles mainly in the abdomen and lower body while suppressing the risk of damage to joints, muscles, ligaments and the like.

  In the present invention, the physical strength augmentation device used in the bathtub, which has the following actions, is placed on both feet and lifted closer to the upper body, thereby promoting abdominal muscle contraction and increasing abdominal muscle mass due to exercise results. It will tighten.

  The embodiment of the present invention will be described with reference to the drawings. The embodiment is composed of a water receiving portion and a water holding portion and a pinching holding portion formed by water injection and both feet, which are formed of an elastic body and used in a bathtub.

  Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a top view showing a physical strength increasing device used in the bathtub according to the present invention, and FIG. 2 is a shape of the physical strength increasing device used in the bathtub. FIG. 3 is a cross-sectional view from the side. 4 and 5 are explanatory diagrams showing the usage state.

  As shown in FIG. 1, the entire circumference is circular, the side is T-shaped as shown in FIG. 2, and the upper part is a water receiving part. An edge is provided there. This is because the abdominal muscles are pushed down to the inner bottom of the bathtub and then pushed up using the abdominal muscles, but at that time, the weight of the hot water is sufficiently received and the load on the muscle is greatly increased.

  The use method of the physical strength augmentation device used in the bathtub is to squeeze the water of the physical strength augmentation device used in the bathtub and the sandwiching holding part by both feet between the shins of the legs or the inner crotch of the upper knee, and place the water receiving part on the foot. Hold and bend both legs while lifting the strength-enhancing device used in the bathtub close to the upper body with the strength of the abdominal muscles.In this case, before reaching the limit of the range of movement, extend all the legs in the opposite direction. If you do a repetitive exercise that lowers the physical strength enhancing equipment used in, the abdominal muscle exercise that fixes the conventional leg and warps the upper body to the back side and then tilts it forward, the upper body warps too much The risk of low back pain increases while you train your abdominal muscles, but the use of a physical strength device in the bathtub moves the lower body without moving the upper body, so there is less strain on the lumbar disc Having the characteristics risk of causing a clause low back pain is extremely low.

  In addition, since it is used underwater, the body floats due to buoyancy, making it difficult to exercise. Therefore, it is possible to maintain a stable posture by grasping the edge of the bathtub with both hands and exercising.

  In addition, there are two types of usage methods in the water, and one of them is the exercise that mainly pours the abdominal muscles by adding water to the pinching and holding part between the water and both feet, offsetting the buoyancy and obtaining a weight load. The second is water injection and the water in the pinching holding part by both feet is increased to increase buoyancy, the same as the abdominal muscle movement, pinched in the inner crotch of the upper knee, while the legs are bent and held in the bathtub while extending the legs downward in the water At that time, an action to get out of the legs sandwiched by the buoyancy is added, and at this time, in order to prevent the legs from coming out from the legs, the inner crotch and the lower half of the body are given a force superior to buoyancy. Need arises. This trains the hip joint and adductor muscle group. The exercise effect can be obtained by repeating this operation.

  As another example of exercise, abdominal muscle exercises can be performed by sitting on a chair in a place other than a bathroom, placing a physical strength-enhancing device to be used in the bathtub above the knee, sandwiching it with the inner crotch, and raising and lowering the legs. It can be used easily during lunch breaks in the office or on the sofa in the living room while watching TV.

  It can be used indoors even on days when you do not take a bath, and as a variable weight physical strength augmentation device with the amount of water put inside, hold the lower part of the main body near the ankle or knee and put the upper part of the main body on the foot, The muscles of the abdomen and lower body can be trained by bending the knees and raising them closer to the upper body while sitting with both hands.

  The above-described invention can be used as a rehabilitation tool for low back pain and hip joint pain because it can be exercised while warming the body by the action of hot water when used in a bathtub.
