Description

FIELD OF THE INVENTION

The invention relates to the field of construction of sports facilities, in particular to the field of construction of football stadiums and fields.

State of the art

The closest analogue of the claimed invention can serve as a device according to US patent US 5605721, equipped with artificial coating, and artificial coating is made in the form of a set of interconnected volumetric elements.

However, the coating does not provide an increase in the load on the thigh muscles (the tailor muscle, which bends the thigh and lower leg, rotates the thigh outward, and the lower leg inward) and the lower leg (the front tibial muscle, which extends and leads the foot) of a person’s legs during sports and playing football field.

Disclosure of invention

The objective of the invention is to intensify the training of football players.

The problem is solved due to the fact that the football field is equipped with artificial turf, and artificial turf is made in the form of a set of interconnected volumetric elements and differs from the prototype in that volumetric elements are made of foam rubber with a volumetric element thickness from 0.13 m to 0.5 m, while the coating is layered, the upper layer is made with an apparent density of 10 kg / m ³ to 39 kg / m ³ , and the lower layer is made with an apparent density of 40 kg / m ³ to 200 kg / m ³ .

The technical result of the invention is to increase the load on the thigh muscles (the tailor muscle, which bends the thigh and lower leg, rotates the thigh outward, and the lower leg inward) and lower leg (the front tibial muscle, which extends and leads the foot) of a person’s legs during sports and games on the field .

Medical observations of the work of the muscles showed that while running on the claimed coating with a thickness of 0.13 m to 0.5 m, the effect of increasing muscle volume over a fixed period of time is most pronounced. Running on such a coating gives an effect similar to using a simulator.

It was found that with a coating thickness of up to 0.13 m, the effect of increasing muscle volume is not very pronounced. With a coating thickness of more than 0.5 m, the effect of an increase in muscle volume is observed, but it (the effect) no longer grows, and the material consumption of the coating increases.

Observations showed that when running on the claimed coating, the volume of fibers in other muscles also increases:

the quadriceps femoris, which extends the lower leg;

the crest muscle, which bends and leads the hip;

the biceps of the thigh, which extends the thigh, bends the lower leg, the bent lower leg rotates outward.

In addition, during training on the claimed coating, the stimulation of the vestibular apparatus is enhanced. There is an improvement in coordination of movements. The outflow of blood from the lower extremities to the heart increases. Additional stimulation of the heart muscle occurs, as a result of which (the passage of blood through the pulmonary circulation), the body is supplied with additional oxygen.

Structurally, volumetric elements can be connected using fastening elements (ropes, belts, fasteners and other elements). In addition, the elements can be glued together with glue.

In the case of impregnation of the coating with water, additional difficulties are created for moving around the coating, which can be useful during training. At least part of the volumetric elements is made with a stress value at 40% strain from 1 kPa to 10 kPa. At least a part of the volumetric elements is made with a tensile strength of 50 kPa to 200 kPa.

Brief Description of the Drawings

The drawing shows a football field with a foam coating (figure 1 and figure 2).

The implementation of the invention

The football field consists of interconnected by means of adhesive foam rubber volume elements 1. Foam rubber elements form an artificial coating. Foam elements are attached to the base 2, made of plastic. Foam elements can also be located on the ground (under the open sky) or on the floor in the gym. If necessary, limit the flow of moisture into the foam elements on an artificial surface with a plastic film. The thickness of the bulk foam element is 0.5 m (it can be selected from the range from 0.13 m to 0.5 m). Volumetric elements are made with a voltage value at 40% strain of 1 kPa. Volumetric elements are made with a tensile strength of 50 kPa. Part of the coating has an upper layer 3 and a lower layer 4, which differ in stress at 40% deformation. The magnitude of the stresses of the layers is 2 times different. The top coating layer is made of bulk elements with an apparent density of 10 kg / m ³ . The lower coating layer is made of bulk elements with an apparent density of 20 kg / m ³ . In order to extend the life of the volume element, the upper part of the volume element can be made with an apparent density of 50 kg / m ³ to 200 kg / m ³ and the rest of the element with an apparent density of 10 kg / m ³ to 49 kg / m ³ . Used playground for sports and games as follows. Football players train on the field - play football. It is much more difficult for footballers to move on a soft, falling surface than on a hard surface. The ball is always above the toe of a football player’s boot. Upon impact, it is necessary to raise the leg, which makes the game more difficult and intensifies the training. If a player falls on the cover, the likelihood of serious injury is reduced.

Due to the fact that it has become more difficult to move around the field, the training time can be reduced. The area with foam coating can be made both in the size of a traditional football field, and in smaller sizes (with a surface area of 100 m ² ). After training on such a field, playing on a regular football field will be more productive.

Studies have shown that with the implementation of the invention will increase the load on the muscles of the thigh (tailor muscle, which bends the thigh and lower leg, rotates the thigh outward, and lower leg inward) and lower leg (the front tibial muscle, which extends and leads the foot) of the person's legs during exercise sports and games on the site.

In addition, the volume of fibers in other muscles increases:

the quadriceps femoris, which extends the lower leg;

the crest muscle, which bends and leads the hip;

the biceps of the thigh, which extends the thigh, bends the lower leg, the bent lower leg rotates outward.

Due to the increase in the intensity of the training, its time can be significantly reduced.

Thus, the objective of the invention is solved.
