Elliptical exercise device for simultaneous training of shoulder girdle, pelvic girdle and trunk muscles in a human
The invention relates to the field of sports and medicine, specifically to training devices, more particularly to an elliptical exercise device suitable for simultaneous training of shoulder and pelvic girdle muscles in a human. Accordingly, it is desirable to provide an exercise device for training trunk muscles, the shoulder girdle and the pelvic girdle in a human and, at the same time, to enable simulation of various motion patterns by activating different groups of muscles, joints, the locomotor system in a human in general and especially muscles which hold the vertebral spine. It is further desirable to enable optional correction of their load during the process of coordination of motor activity (locomotion) of the human body through simultaneous elliptical motions of hands and feet, which, in addition to the load on the shoulder girdle and the pelvic girdle muscles, simultaneously provide preferably stretching load on muscle groups which hold the vertebral spine.
1. An elliptical exercise device for simultaneous training of a shoulder girdle, a pelvic girdle and trunk muscles in a user, the device comprising an exercise device body including an arm load unit having a first hand pedal and a second hand pedal attached thereto and a leg load unit having foot pedals attached thereto,
wherein the arm load unit and the leg load unit are configured to enable the first and second hand pedals and the foot pedals to perform elliptical motions independently from each other,
wherein the arm load unit comprises a first flywheel to which the first hand pedal is coupled and a second flywheel to which the second hand pedal is coupled,
wherein the first flywheel is mounted to a first ball joint configured to allow the first flywheel to rotate in a first direction parallel to the ground, such that a first angle measured in the first direction is capable of change, the first angle being an angle between a sagittal plane of a human body of the user of the elliptical exercise device and a plane of trajectory of elliptical motions of the first hand pedal, and
wherein the second flywheel is mounted to a second ball joint configured to allow the second flywheel to rotate in the first direction, such that a second angle measured in the first direction is capable of change, the second angle being an angle between the sagittal plane of the human body of the user and a plane of trajectory of elliptical motions of the second hand pedal.
2. The elliptical exercise device of claim 1 , further comprising a removable supportive platform.
3. The elliptical exercise device of claim 2 , wherein the removable supportive platform is configured to be located at the level of the chest segment of the human body of the user.
4. The elliptical exercise device of claim 1 , wherein the exercise device is configured to change a third angle measured relative to the ground, the third angle being an angle of inclination of the arm load unit.
5. The elliptical exercise device of claim 1 , further comprising a mechanical lock configured to set kinematic parameters of elliptical motions of the first hand pedal, the second hand pedal, and the foot pedals.
6. The elliptical exercise device of claim 1 , further comprising a telescopic mechanical connection configured to adjust a distance between the arm load unit and the leg load unit.
