Rope-jumping is jumping from tall objects (bridges, towers, rocks) using professional climbing gear. This extreme kind of sport appeared about 20 years ago, and recently became popular in Ukraine. A peculiarity of rope-jumping is that the jump is completed with the "pendulum". Due to the specifics of a rope and a method of fixing of equipment the jerk is smoothed that makes a leap comfortable and prevents an injury of the spine. All elements of the system are duplicated, and it minimizes the risk of failure of any of the items.
Bungee jumping, unlike the rope jumping, involves jumping using an elastic cord attached to the legs. Sometimes it is possible to fix the cord around the legs and chest for more comfort and safety. During the bungee-jump the cord stretches and the jumper flies upwards again as the cord recoils, and continues to oscillate up and down until all the energy is dissipated. There are also jumps with partial immersion in water. These jumps require more precise calculations.
The first modern bungee-jumps for fun and getting adrenaline were made at the end of the 1970s. And some time ago jumping with lianas tied to the feet was part of the rituals of the tribes of South America and Oceania. Bungee jumping became popular after the New Zealand athlete A J Hacket made an unauthorized jump from the Eiffel Tower from a height of 114 meters - a jump that could not remain without attention. It was after this desperate act of the New Zealander that fans of extreme sports became interested in bungee-jumping.
In order to jump with an elastic cord from a tall object, a person must have no medical contraindications. In particular, it is forbidden to jump with heart diseases, high blood pressure, nervous disorders, epilepsy. There are also certain age and weight restrictions. In Ukraine, jumping with elastic cord is permitted only for adults or children above 16 years old with a parental consent. Equipment for jumping is suitable for a weight in the range from 45 to 115 kg. In Ukraine, the equipment for rope and bungee-jumping should be certified by UIAA (the International Mountaineering and Climbing Federation). Each rope or elastic cord has a limit of a number of jumps, so equipment must be regularly replaced.
Slacklining is a kind of outdoor activity that involves walking on a tight strap. Slacklining is distinct from traditional tightrope walking in that the line is not held rigidly taut. Thus, the balancer must adjust a rope to his center of gravity. The following things are usually used for slacklining: a nylon webbing that is 2,5-6 cm wide, a cord or metal cable with a diameter of 3-6 mm. On gaining the basic skills of walking on a rope, you can learn to run and perform certain acrobatic tricks on it. Slacklining is divided into the following types: low-line (a rope is fixed on a small height above the ground/water), waterline (a rope is fixed over the water surface), highline (slackline at high altitude, with insurance).
