Sports rope: description, varieties, application

There are many different simulators for sports. Some software-controlled models are more like a spaceship than a conventional treadmill. Along with cutting-edge developments, very simple, familiar shells, such as a sports rope, do not lose their relevance.

History

The first mention of it refers to ancient times, by 129 AD. Rope climbing perfectly trained strength and endurance. Later, the exercise was highlighted in a separate kind of gymnastics program. From 1896 to 1932, even Olympic awards were played out.

At first the height of the lift was 14 meters, the winner of 1896 was able to complete the task for 23.4 seconds. Then the height was reduced to 7.62 m, the Olympic record - 6.7 s.

The second birth rope sports for climbing found in the 90s of the last century in the Czech Republic, where national competitions are held annually. The record of overcoming the shell length of 8 meters is only 5.5 seconds.

In sports

Products can be different in thickness, the method of weaving, the material of manufacture. Rope sports a child, usually a small diameter. The small handle is unable to securely fix the thick rope. When it is made using cotton fiber, soft and durable, it can be painted in any color. Children with pleasure learns such a simulator for about three years. It helps to strengthen the muscles of the hands, develops skill and dexterity. Ropes for the sports corner (children's) are sometimes made with knots at a certain distance for the convenience of children.

Traction requires the product to be particularly strong. Efforts are simultaneously applied by a group of people, sometimes several dozen. On both sides wrapped with tape, in order to protect the fibers from rastrepyvaniya. Length - at least 33.5 meters, according to existing rules, one team must consist of at least 8 players.

The sports rope is great for dropping excess weight and intensive training of athletes. Crossfitters use a horizontal variant, practicing mahi, blows, throws. One end of the projectile is securely fixed in the wall or floor, the free ends with a special anti-slip coating (in order not to rub palms and not to be disheveled) are picked up. The rope is massive, 6-10 meters long.

Requirements

The definition of a rope is as follows: a strong, thick rope of synthetic, metal or vegetable fibers intertwined in a certain way. Despite the different target use of the projectile, it should be:

• Antiallergenic;
• Smooth, but not slippery;
• Do not heat up when downhill;
• Strong;
• Thick enough (in diameter).

Absolutely all products are tested for tearing. This is an elementary safety requirement when using a rope.

Material

Materials are divided into two groups: plant and synthetic. Each of them has its advantages and disadvantages:

• Jute. An annual plant of up to 4 meters in length grows in China, India, Egypt. The sports rope is weaved from 3-4 veins according to the technology worked out for centuries. Modern technology allows you to provide the necessary thickness and strength. Characteristic:

- ecologicaly clean;

- resistant to ultraviolet light;

- antistatic;

- wear-resistant;

- has a low weight.

• Cotton. Ropes for the sports corner (children's) are made of this material. Characteristic:

- excellent hygienic indicators;

- Elastic;

- resistant to relatively high temperatures;

- does not accumulate static electricity;

- poorly tolerates moisture (subject to rotting);

- there is no breaking of fibers (at bends);

- has an attractive appearance;

- little weight;

- resistant to breaking load;

- wear-resistant.

• Sisal. Woven-twisted ropes are made from agave leaves fibers, growing in Kenya, Brazil, Tanzania. Characteristics:

- strong;

- eco-friendly;

- durable;

- easy;

- Elastic;

- Soft.

• Manilsky. Abaca, or manila, is a natural fiber extracted from a textile banana. It grows in the Philippines and the Moluccas. Characteristics:

- eco-friendly;

- hygroscopic;

- strong;

- it has a minimum degree of slip;

- high breaking force.

• Polypropylene. This is an artificial material, a multifilament fiber or a film filamentary filament. Characteristics:

- smooth;

- resistant to bending;

- has increased resistance to aggressive media;

- easy;

- wear-resistant;

- Does not rot;

- Elastic;

- poorly tolerates direct sunlight, deformation reaches 15% (lengthening of the rope).

Applications

A braided or twisted article with a minimum diameter of 8 mm can be considered a rope. Everything that is thinner refers to ropes or cords. The scope of application is very extensive. Ropes can be divided into groups:

• Sea, are used in shipbuilding, marine and river business;
• Rigging (rigging on a ship);
• Load-lifting, with their help lift and move loads;
• Towing, without them towing of vehicles is impossible;
• Decorative, they design rooms, interior items, furniture;
• Rope sporting as a projectile in separate disciplines and for training.

There are many other branches of human activity where it can come in handy. Despite the various technical characteristics, the ropes fulfill one task - they withstand the high loads imposed on them.

Selection

In specialized stores you can choose the appropriate sports rope. The price depends on the material of manufacture, brand, length and diameter of the product. It ranges from 120 r. For one running meter up to 3000 r. and higher. Large selection and fasteners. It is purchased in a set or separately.

The main criteria are the operating conditions. You should take into account such nuances: the method of fastening, the humidity of the room, the purpose of use. Correctly selected projectile will serve for more than one year and will ensure safety during operation.
