Leg strength training device used for athletic training

Abstract

The invention provides a leg strength training device used for athletic training. The leg strength training device comprises a fan and a flexible supporting frame; the bottoms of two supporting columns are installed at the left end and the right end of the end face of the top of a base respectively; the bottom of a base plate is installed in the middle of the end face of the top of the base, and the end face of the top of the base is inclined; the bottom of a backrest plate is inserted into the rear end of the end face of the top of the base, and the front end face of the backrest plate is inclined; a power switch is installed at the top of the rear end of the base and connected with an external power supply line; stress rotating rods are connected with the supporting pillars, the bottomsof the stress rotating rods are cylindrical, and external threads are arranged at the bottoms of the stress rotating rods; a lifting rod is connected with the two stress rotating rods, and flexible sleeve pillars are installed on the lifting rod. In this way, when the legs of a person straighten forwards and are bent backwards, pressure is exerted continuously on the legs, the muscles of the legsare kept in a stressed and tensioned state, and the effect of practicing the muscle groups of the legs is realized.

Description

technical field [0001] The invention belongs to the technical field of sports training equipment, and more specifically relates to a leg strength training device for track and field training. Background technique [0002] Track and field is one of the sports that are highly spectator in sports competitions, and track and field mainly examines the athlete's explosive power, endurance, speed, etc., and the completion of this sport mainly depends on leg strength, so the training of leg strength extremely important. [0003] Based on the above, the inventors found that the existing leg strength training device, such as the leg strength training device for track and field athletes mentioned in the patent application number CN206809642U, includes a seat, a machine base, a rubber tensioner, a leg kicking device, a pedal Force device and bearing, characterized in that: the seat is located on the leftmost side of the training device, the machine base is made of aluminum material and...
