Description

Fencing auxiliary training device and training method thereof

Technical Field

The invention relates to the field of fencing, in particular to a fencing auxiliary training device and a training method thereof.

Background

Fencing is one of the sword sports. The athlete holds a slender elastic steel sword with a hand, wears a mask and specified clothes, and plays a game on a rectangular field. The victory or defeat is determined according to the set time and the number of swords in the thorns (wedges).

The fencing competition is carried out on a metal track with the length of 14 meters, the width of 1.5-2.5 meters and the height of 10-50 centimeters. The metal track has the function that no signal is displayed when the athlete intentionally and unintentionally pricks on the playing field. Two ends of the metal channel are respectively provided with a wire dragging disc, wires which can freely pass in and out are arranged in the wire dragging discs, the wires are communicated with the wires on the bodies of the athletes, and the wires on the bodies of the athletes are communicated with the swords. Thus, the two athletes, the referee and the wire supporting disc are mutually connected to form a ring-shaped circuit. Whenever one stabs the other with sufficient pressure, the circuit is completed and the referee is signaled. The device can help the referee to make analysis and judgment.

Fencing sportsman not only will contact the action of hand in fencing training at ordinary times, will carry out the paces training of foot equally to reach quick effect that is rectilinear movement, but when training, the training process is comparatively lasting and very fast, hardly audio-visually sees the straight line shape of removal route, leads to training effect and efficiency relatively poor, and in long-time training, the continuous effect that receives of the power of foot leads to the ankle to be injured easily.
