Description

Sail-swinging sports simulation device and physical training method

Technical Field

The invention relates to a sail-swinging sports simulation device and a physical training method, which are particularly suitable for sail-swinging sports, mother case CN202010128817.2, application date: 2020-02-28.

Background

As one of competition projects, training is mostly performed by means of water surface training, but the training is often limited by various conditions such as environment and weather, so that land simulation training is often performed to improve training efficiency and training effect.

Since the international interlining releases the rules that limit sailing, sailing has become a key factor in making winnings in sailboard competitions. Therefore, sailboard athletes in all countries strengthen the training of special physical ability and special skill of sail reeling with the help of auxiliary training instruments. The existing method is that the athlete grasps the rope with the arm, the rope is connected with the weight through the pulley (changing direction), the arm simulates the action of swinging the sail to do the back and forth movement to drive the weight to lift, the gravity of the weight is converted into the resistance of the arm movement of the athlete, and the athlete must try to make the upper limb and the whole body move coordinately to overcome the resistance. The resistance of this mode is generated by the weight of the weight and is a fixed value in motion. In addition, during the training process, various motion parameters and body parameters cannot be monitored and displayed in a real-time and quantitative manner, so that the sail swinging process cannot be analyzed and trained scientifically in a quantitative manner.

In fact, the resistance of the athlete during training and sail competition changes continuously along with the force, is a compliant resistance, is similar to an equal dynamic resistance, and is greatly different from the fixed resistance provided by the original land simple training instrument, so that the athlete feels uncoordinated and unrealistic, the physical ability of the athlete cannot be reasonably utilized in the training and the competition, the optimal sail shaking effect cannot be fully exerted, the sport performance is influenced, and sport injury is extremely easy to cause to the athlete. In order to avoid the influence of climate and weather and meet the requirement of scientific training, a land sail-reeling simulation training device which can simulate wind power as much as possible and realize reverse force application of athletes is developed, the wind resistance characteristic of the actual sailboard is simulated to the maximum extent, and the land sail-reeling simulation training device is a requirement of experts, coaches and athletes in the sailboard field in China for many years.

Although the CN200410035580.4 sailboard sail-reeling simulation training device and the CN201620202572.2 sail-reeling simulator provide two types of sail-reeling simulators, they cannot realize reasonable wind power simulation and reproduce the situation of simulated water surface, and in actual use, they will give an illusion to the athlete, thereby affecting the normal performance of the athlete in actual movement.
