Further, an angle measuring device 109 is provided in the limiting shaft, and the device may be an inclinometer or an electronic protractor, which is not limited in the present invention. Taking the electronic protractor as an example, as shown in Figure 2, the electronic protractor is arranged on the extension frame extending from the seat frame to the limit shaft, and the initial position of the seat frame is the 0° position, and the angle measured by the electronic protractor is the seat frame. Rotation angle, the electronic protractor is connected to the processor. During the evaluation or training of the heel raising, the electronic protractor uploads the measured rotation angle of the seat frame to the processor, and the processor uses the formula h=Lsinα to obtain the heel raising height, where h In order to raise the heel height, L is the distance from the limit shaft to the leg press plate, and α is the angle measured by the electronic protractor.

When the foot extends into the pedal, the arc clamp arm is pushed by the foot. According to the size of the foot, the included angle of the two arc-shaped clamping arms changes correspondingly, and at the same time, under the reaction force of the spring element, an angle suitable for the size of the foot is formed.

In the embodiment of the present invention, the size of the opening angle of the arc-shaped clamping arm is used to adjust the size of the foot pedal. The larger the foot, the larger the opening angle of the arc-shaped clamping arm. The smaller the opening angle, the smaller the foot pedal, the user can actively adjust the size of the foot pedal according to the size of the foot, so as to avoid insufficient force due to the wrong size of the foot pedal.

As an optional implementation manner, as shown in FIG. 3 , uniformly distributed elastic columns are provided on the footboard, and the elastic columns are retracted into the footboard under force.

The elastic column is an evenly distributed movable element with micro-protrusions on the surface of the foot pedal, when an external force is exerted on the surface of the elastic column, it retracts into the foot pedal, and presents the shape of a force applying object on the surface of the foot pedal.

In the embodiment of the present invention, the elastic column arranged on the surface of the foot pedal is used to observe the size and shape of the force-bearing surface of the footboard when the user evaluates the strength of the calf, and the user's exertion habits are analyzed according to the size and shape of the force-bearing surface. Combined with the results of the calf strength evaluation, users can customize their own training plans according to their own conditions, so as to improve training efficiency and training effects.

As an optional embodiment, the described calf strength evaluation and training device also includes:

The acceleration sensor is arranged in the leg press plate, is electrically connected with the processor, and is used for measuring the acceleration of the human body when raising the heels.

In the embodiment of the present invention, the acceleration sensor is used to measure the acceleration of the leg press plate during the calf strength evaluation process, and the data is accurate and can more intuitively observe the acceleration change during the calf strength evaluation process. Then adjust the user's training plan.

As an optional embodiment, the described calf strength evaluation and training device also includes:

A power supply module, connected to the pressure sensor, the angular velocity sensor and the processor, respectively, and used for providing electric power to the pressure sensor, the angular velocity sensor and the processor.

The power supply module is used to supply power to the pressure sensor, the angular velocity sensor and the processor, and the power supply module may be a lithium battery or a dry battery, which is not limited in the present invention.
