Description
Technical Field
The invention relates to the technical field of sports equipment, in particular to intelligent training equipment for simulating sitting cross-country skiing.
Background
Cross-country skiing is a traditional project of winter Olympic, and in particular sitting cross-country skiing, the performance of which is very dependent on technical movements and the magnitude of work output of the athlete's upper limbs. Cross-country skiing is a large scene of movement where it is difficult for a coach to track athletes from time to accomplish technical action supervision and correction. This requires that we have corresponding proprietary training equipment in the room to ensure that athletes can simulate outdoor cross-country skiing in local space.
There are also some specific indoor skiing training devices, such as existing sitting gesture ski simulators, which use two hands to pull two grips obliquely above, the grips providing resistance by connecting the flywheel with a rope. The device calculates the work output by the upper limb by counting the rotation speed of the flywheel. But the problem is that this statistics is the output of the hand tension and not the work of the skiing action.
Although some in the art have improved the above-mentioned equipment, designed the structure of ski pole + slide rail, ski pole connection slide rail, slide rail pass through the rope and connect the flywheel and provide resistance, just so can count the upper limbs output work of skiing action. While previous studies and designs have been primarily explored for simulating cross-country skiing, there are a number of problems such as:
1. Sitting skiing is a disabled and unoccupied item, wherein different athletes relate to different force-exerting modes of disabled parts, and a seat is not only used for distinguishing sitting postures and kneeling postures, but also needs to meet the function of adjusting angles in a proper range;
2. The current upper limb output work is completed by counting the work done by the skiing action on the flywheel or the balancing weight, and whether other related parameters assist statistics exist or not, for example, the forward impact force of the skiing in the skiing process can not be collected;
3. The device can analyze the angles of all joints of a body through the gesture capturing system, but does not collect the boundary force of the human body, and cannot perform accurate human dynamics analysis, so that the stress condition of important muscle groups of the human body in the skiing process cannot be obtained;
4. The correct skiing posture is that the two arms exert force in parallel, but uneven force can be involved in the field road condition in the cross-country skiing process or the force cannot be exerted in parallel, and the measurement and analysis of the stress condition of important muscle groups of the body in the case need a specific slideway mode to assist in completion;
