Definitions
- the present invention relates to a sports device and, in particular, the present invention relates to a sports device for posture stabilization in the case of a hip and knee extension of a person and a seat pan for a sports device.
- hip and knee extension to train the buttocks and thigh muscles is indispensable.
- This hip and knee extension is commonly referred to as a squat.
- the athlete does not use any additional weights, but crouches while keeping a straight back section, if possible, and gets up again.
- FIG. 11 In order to stay in balance, it is necessary for the athlete to perform a slight forward balancing movement with the upper body in order to keep the center of gravity above the ball of the foot. As can be seen in FIG. 11, this leads to a wide forward bending of the upper body and a large buckling of the knees.
- the angle between the athlete's upper body and thighs becomes less than 90 °.
- This also leads to an angle ⁇ between the knees and the calf area of the athlete becoming less than 90 °.
- both angles a and ß move in a range from 30 ° to 60 °. This leads to a very heavy load on the knee joints.
- a barbell bar is usually used for this, which is placed on the shoulder area of the athlete.
- this weight can be up to 150 kg or more. If the athlete now moves with the weights on his shoulder into the position shown in FIG. 11, in which the angles ⁇ and ⁇ are far less than 90 °, there are heavy loads on the joints. In addition, any "inaccuracy" of the movement immediately leads to a very heavy load on the back area of the athlete. In particular, these irregularities occur in the movement of the athlete when fatigued or in the case of non-trained athletes. These irregularities result in the movement damage to the spine and spine as well as the knee joint within a very short time.
- a sports device for posture stabilization in the case of a hip and knee extension of a person comprising a seat pan which can be displaced in a vertical direction, the seat pan being designed to accommodate a seat area of the person, the seat pan having a flexible area, to allow stretching and flexing of the person's hip joint and a rigid area which supports a back part of the person, and wherein the sports equipment has means for holding the person's buttocks area in the seat pan.
- the kink angle of the knee joints namely the angle ⁇ in FIG. 11, is also limited to approximately 90 °.
- the hip joint is fixed and forms a starting point for possible weights.
- This sports device advantageously stabilizes the posture of the person during hip and knee extension, thereby protecting the spine. This leads to the avoidance of spinal injuries. It also advantageously leads to that even a beginner in training can do this BC squat exercise without fear of injury.
