Description

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

* The present invention is to implement an exercise suitable for thigh and gluteus maximus exercise such as a leg press or total hip, a stationary indoor bicycle, and an outdoor bicycle while protecting the knee and ankle joints, The present invention relates to an exercise method and exercise device for strengthening the thigh muscles and glutes while protecting the knee and ankle joints by moving the legs with the lower part of the arm on the thigh in a lying position.

To this end, the exercise device according to the present invention includes an arm that is rotatably attached within a radius of a user's pelvis position at a position of 20 cm in the sagittal plane and a seating portion that can sit or lie down, and an exercise configured such that one end of the arm rotatably spans the user's thigh It features a device.

An exercise device according to an embodiment of the present invention includes various resistance force generation units that generate resistance force against a force that a user attempts to rotate an arm portion. In addition, the exercise device according to the present invention includes a shaft conversion unit that allows the user to change the direction of the rotation shaft. Another embodiment of the exercise device according to the present invention includes two different rotation shafts on one arm. In addition, by grafting the exercise device to a bicycle, the rotation axis of the arm part is located at the hip joint and one end of the arm is hung behind the thigh, and it is rotated when rotating in a clockwise direction according to the rotation of the arm part 32 and counterclockwise. It includes an exercise device that drives a bicycle while idling while rotating by driving the rear wheel.

The quadriceps and glutes occupy more than a third of the muscles in our body. Increasing the muscles in this area reduces the risk of diabetes, prevents obesity, and helps promote health after middle age. In addition, it improves the aesthetics of the body and contributes to improving the sports ability of athletes.

However, in general, exercise to strengthen the thigh and glutes is a common disease among muscle strength athletes, such as knee degenerative arthritis and chondromalacia, as a load is applied to the ankle and knee joint. In addition, it is difficult for athletes with weak knee and ankle joints, such as the elderly and obese population, to perform. Therefore, there is a need for an exercise device capable of training the thighs and glutes without stressing the knees and joints.

In general, the exercise for strengthening the thigh and gluteus maximus is performed in a direction in which the leg is pulled toward the chest with the pelvis as an axis and then pushed outward, as shown in FIG. 1. However, the existing exercise method and exercise device can damage the knee joint and ankle joint because the load is transmitted to the ankle or knee as it is, and is unsuitable for users with weak knee and ankle joints to perform. Therefore, in the present invention, a footrest or footrest of an exercise device connected to a weight is placed on the thigh of the leg for exercise, and the user lifts the leg exercising in a sitting, lying, or upright position toward the chest and then rotating it back. As a result, the force transmitted to the knee and ankle is reduced.

When using the exercise device according to an embodiment of the present invention, the user's thigh muscles and glutes are all involved in the extension of the hip joint as well as lateral rotation and adduction. Accordingly, the exercise device of an embodiment according to the present invention includes a shaft conversion unit for converting the direction of a rotation shaft by a user. The rotation shaft may be disposed in a direction in which the user's lower limbs can be rotated in an extension direction. In addition, the rotation shaft may be arranged so that the user's lower limb can move in the directions of pronation and external rotation. The exercise device of another embodiment of the present invention includes two different rotation shafts on one arm, and rotation of different shafts is performed at the same time, so that it is possible to abduct and extend simultaneously.

In addition, the exercise device of another embodiment of the present invention includes a bicycle frame. In the conventional bicycle, the hip joint motion range is limited to within the rotation diameter of the crank arm to which the pedal is attached, as shown in FIG. 2, so that the movement of the lower body is performed only repeatedly in a small section. Therefore, in the present invention, in a bicycle, a propulsion device that fixes the rotation axis of the arm to the position of the user's hip joint, rotates when rotating clockwise according to the rotation of the arm, and drives the rear wheel while idling when rotating counterclockwise to propel the bicycle. It includes an exercise device characterized in that included. On the other hand, U.S. Patent Publication No. US5746688, U.S. Patent Publication No. US5135457, U.S. Patent Application Publication No. US2011/0301002, Publication No. 10-2014-0056481, Japanese Patent Publication No. 4478208, and Japanese Unexamined Patent Publication No. 09 -266958 discloses a prior art for exercise equipment in the related art.

In general, the exercise to strengthen the thigh and gluteus maximus is performed in the direction of pulling the leg toward the chest with the pelvis as an axis and then pushing it outward as shown in FIG. At this time, if the exercise intensity is increased, a burden is placed on the knee joint and ankle joint. However, in the existing exercise equipment, the footrest formed integrally with the arm part provided to be rotatable is located on the ankle or the sole of the foot, so it is often the cause of degenerative knee disease, and users with weak knee and ankle joints use exercise equipment. It was not suitable for use.

In addition, in the case of a general bicycle, as shown in FIG. 2, the range of motion of the hip joint is limited to the radius of movement of the circle in which the crank connected to the bicycle pedal rotates. It can be seen that exercise efficiency is limited in terms of utilization of the quadriceps and glutes.

In the present invention, in an exercise method and exercise apparatus for strengthening the thigh muscles and glutes, the load applied to the opposite leg is reduced by the user taking a sitting, lying, or prone position during the exercise operation. In addition, it is characterized by minimizing the load transmitted to the knee and ankle joint by moving the leg by placing the lower end of the arm on the thigh rather than the ankle or sole. And by expanding the range of motion and rotational axis of the hip joint, the effect of the exercise to strengthen the thigh and gluteus maximus is increased.

When a user with a weak knee or ankle joint or an exerciser who wants to strengthen the thigh and gluteus maximus muscles without a problem with these joints performs an exercise to strengthen the thigh and gluteus maximus with the exercise device of the present invention, strengthen the muscles and in the long term, diabetes, etc. It can help reduce the risk of health, prevent obesity and promote health after middle age. In addition, according to the exercise device of the present invention, it is possible to help improve the body aesthetically and contribute to the athlete's ability to improve sports without difficulty in the knee and ankle joints.
