Wheatstone bridge-based human-body acceleration or power-generation capability comparing device

Abstract

The invention discloses a Wheatstone bridge-based human-body acceleration or power-generation capability comparing device, which is characterized by comprising a platform. The front end of the platform is hinged onto the upper end of a support arm fixed on the ground. A telescopic mechanism capable of telescoping along the vertical direction is arranged between the rear end of the platform and the ground. The platform is provided with two guide rails arranged to extend from the front part of the platform to the rear part of the platform. Two pedals are arranged in tandem on the guide rails. The front ends of the two pedals, on the platform, are respectively provided with a limiting block. The lower parts of the two pedals are respectively provided with a resistive film in the same direction with the guide rails. The front / rear ends of the two resistive films are in connected conduction with the same guide rail through inflective wires. The two resistive films, correspondingly arranged below the two pedals, are respectively provided with movable contacts fixed on the platform and in contact with the resistive films. In this way, a person best in acceleration capacity and the difference between the acceleration capacities of people can be conveniently judged. Meanwhile, a person shortest in the reaction time of start can be judged, so that the reaction speed capacities of people can be judged.

Description

technical field [0001] The invention relates to a physical training device, in particular to a device for comparing human acceleration or exertion ability. Background technique [0002] In life, people participate in various sports and activities. In order to achieve good results and enhance their physical fitness, a lot of training is required, and each item must be targeted, such as explosive training. People in motion start from rest Need to have a certain acceleration ability. At present, the training methods of this acceleration ability are very rich, but the means of how to judge and evaluate each person's acceleration ability are still very lacking. The standard for athlete selection is also very vague, which is not conducive to excellent athletes The selection of sports, especially track and field, still needs to be improved and perfected technically. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention provides ...
