The leg strength training device is simple in structure, convenient to use, high in comfortableness, low in cost and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of sports training devices, in particular to a leg strength training device for track and field athletes. Background technique [0002] There are a lot of equipment for physical exercise, and there are very few equipment for track and field athletes' leg strength training. The leg strength training of track and field athletes is mainly for leg explosive power and endurance. Normally, weight-bearing running exercises are carried out on the playground. This kind of exercise takes a long time and the effect is average. The Chinese patent number is: 201620090098.9 The track and field athlete leg strength training device, It is composed of seat, backrest, backrest knob, outrigger, base, bracket, gear, flywheel and tooth chain: the track and field athletes leg strength training device drives the gear by stepping on the pedal with both feet, and then drives the flywheel through the tooth chain. By adjusting the kn...

The leg strength training of track and field athletes is mainly for leg explosive power and endurance. Normally, weight-bearing running exercises are carried out on the playground. This kind of exercise takes a long time and the effect is average. The Chinese patent number is: 201620090098.9 The track and field athlete leg strength training device, It is composed of seat, backrest, backrest knob, outrigger, base, bracket, gear, flywheel and tooth chain: the track and field athletes leg strength training device drives the gear by stepping on the pedal with both feet, and then drives the flywheel through the tooth chain. By adjusting the knob to control the friction coefficient between the flywheel and the friction plate to control the strength of the legs, although this device can be used for indoor training, but without a shock absorber, the vibration generated by the athlete during exercise will cause discomfort and affect the use of the device life, and the resistance adjustment structure of the device is complicated, the cost is high, and it is not easy to maintain
