Problems solved by technology

[0003] At present, what is used in China is mainly weight-bearing strength training, which is usually called "barbell training". This training method uses the same force in the process of stretching and stretching the legs. Simulate the load form of special sports to the greatest extent
For some foreign trainers, such as Cybex’s Eagle Leg Press, Freemotion’s EPIC Leg Press and Calf, Hoist’s VLP, etc., these trainers are double-leg support kicks, except for the way of providing loads. "Barbell training" also has the disadvantage of inappropriate exercise load
Keiser's Air300 Leg Press has improved this training method and realized the way of separate training with one leg, but it cannot meet the load form of one-way load

Abstract

The invention relates to a seat leg trainer with which can synchronously train two legs backwards and forwards. The invention mainly comprises a chair, left and right pedals, and transmitters connected with the pedals, two groups of tracks, and an angle adjuster, an adjustable damping device fixed on the bottom support, a synchronous steering device, a position adjuster, a tension device, and a data collecting displaying processing system. The invention has adjustable angle between two legs, to synchronously train two legs, and realize one-leg periodical alternation and one-way load method. The invention provides training platform to linearly adjust the train load, to meet different heights and knee angles, while it can collect, store, and real-time display the parameters in the train.

Description

technical field [0001] The invention relates to a seated leg strength training device capable of synchronous retreat training for both legs, and belongs to the technical field of physical training and training equipment. Background technique [0002] For most sports, the movement of the athletes' legs alternates periodically during the competition, and the weight-bearing direction of the legs is unidirectional. For example, in ice skating, the athletes exert their strength in the kicking phase, while the load in the retracting phase is small; Therefore, in order to effectively improve the specific strength level of athletes' legs, it is necessary to adopt a training form suitable for this state. [0003] At present, what is used in China is mainly weight-bearing strength training, which is usually called "barbell training". This training method uses the same force in the process of stretching and stretching the legs. Simulate the load form of special sports to the greatest...
