Description

{Exercise device to preserve ankle and knee joint while exercising upper leg and hip}

The present invention is intended to provide exercise for protecting the knee and ankle joint, which is suitable for femoral and gluteal muscles such as a leg press or a total hip, a fixed indoor bicycle, an outdoor bicycle, The present invention relates to a motion method and an exercise device for strengthening a femoral muscle and a dumbbell while protecting the knee and ankle joint by moving the leg with the lower end of the arm placed on the thigh.

To this end, the playground according to the present invention comprises a sitting part capable of sitting or lying down, an arm rotatably attached within a radius of 20 cm of the pelvis position of the user on the sagittal plane, and a motion configured such that one end of the arm rotates on the user's thigh And a device is provided.

The exercise device according to an embodiment of the present invention includes various resistance force generators for generating a resistance force against a force that the user is trying to rotate the arm portion. In addition, the athletic apparatus according to the present invention includes an axis change unit that allows the user to change the direction of the rotation axis. The playground of another embodiment according to the present invention includes two different pivot shafts in one arm portion. In addition, the exercise device is attached to the bicycle, and the pivot axis of the arm portion is positioned at the hip joint portion, one end of the arm is arranged to cover the back of the thigh, and is rotated in the clockwise direction in accordance with the rotation of the arm portion 32, And an exercise device that drives the rear wheel to propel the bicycle while idling while rotating.

The femoral muscle and gluteus are more than one third of the muscles in our body. Increasing the muscle in this area reduces the risk of diabetes, prevents obesity, and helps promote health after middle age. In addition, it aids the body in aesthetic and contributes to the improvement of athletes' sports ability.

However, in general, exercises to strengthen the femoral and gluteal muscles are applied to the ankle and knee joints, and knee degenerative arthritis and osteoarthritis are common diseases of the muscular exerciser. In addition, it is difficult to exercise with weak knee and ankle joints, such as elderly people and obese people. Therefore, an exercise device capable of training the femoral and gluteal muscles without stress on the knees and joints is needed.

In general, the exercise for strengthening the femoral muscle and gluteus is performed in a direction in which the leg is pulled toward the chest and pushed outward with the pelvis as an axis as shown in Fig. However, the existing exercise method and the athlete's foot are transmitted to the ankle or the knee as they are, so they can damage the knee joint and the ankle joint, and it is not suitable for the users who have weak knee and ankle joints. Accordingly, the present invention is directed to a method and apparatus for positioning a footrest or footrest of a fitness instrument connected to a weight on a thigh of a moving leg, and lifting a leg that the user is sitting on, lying down, or in an up- So that the force transmitted to the knee and ankle is reduced.

When using the exercising apparatus according to an embodiment of the present invention, the user's femoral and gluteal muscles are involved not only in the extension of the hip joint but also in lateral rotation and adduction. Therefore, the exercise device of one embodiment according to the present invention is provided with the axial conversion section for the user to change the direction of the rotation axis. The pivot axis may be arranged in a direction in which the user can rotate in a direction in which the base of the user is stretched. In addition, the rotation axis can be arranged so that the user's lower extremity can move in the directions of adduction and external rotation. The motion device of another embodiment of the present invention includes two different pivot shafts on one arm and is rotated at different shafts at the same time, so that it is possible to perform simultaneous extension and extension.

In addition, the playground of another embodiment of the present invention includes a bicycle frame. In the conventional bicycle, the range of motion of the hip joint is limited to the rotation diameter of the crank arm with the pedal attached as shown in FIG. 2, so that the movement of the lower body is repeated only in a small section. Therefore, according to the present invention, there is provided a bicycle comprising: a propulsion unit that fixes a rotary shaft of an arm at a position of a hip joint of a user and rotates in a clockwise direction in accordance with a rotation of the arm and idles in a counterclockwise direction to drive a rear wheel, The present invention includes a fitness machine.

In general, the exercise for strengthening the femoral muscle and the gluteus maximus is performed in the direction of pulling the leg toward the chest and pushed outward with the pelvis as an axis as shown in Fig. At this time, when the exercise intensity is increased, the knee joint and the ankle joint are burdened. However, since the existing exercise equipment is located on the ankle or the sole of the foot, which is integrally formed with the arm portion, which is rotatably provided, it often causes degenerative knee disease. In the case where the knee joint and the ankle joint are weak, It was unsuitable for use.

In addition, as shown in FIG. 2, in the case of a general bicycle, the range of motion of the hip joint is limited to the radius of motion of the rotating circle of the crank connected to the bicycle pedal. Therefore, And the exercise efficiency is limited in terms of utilization of the femoral muscle and gluteus maximus.

The present invention relates to a method and a device for exercising a femoral component and a gluteus maximizing a load applied to an opposite leg by a user sitting, lying down or lying down during a movement. Further, the lower end of the arm is placed on the thigh rather than the ankle or the sole, and the leg is moved to minimize the load transmitted to the knee and the ankle joint. By increasing the range of motion and the axis of rotation of the hip joint, the effect of strengthening the femoral and gluteal muscles is enhanced.

When a user with weak knee or ankle joints or an athlete who intends to strengthen the treadmill and gluteal muscles without causing such joints exercises the femoral and gluteal strengthening exercises with the exercise device of the present invention of the present invention, the muscles are strengthened and, in the long term, Reducing the risk of obesity and helping to improve post-MI health. Further, according to the exercising apparatus of the present invention, it is possible to help the body aesthetically and to help the athlete to improve the sports ability without any difficulty in the knee and ankle joint.
