1, rope climbing rope can be divided into the main rope and auxiliary rope. The thickness of the main rope is about 9-10 centimeters, in principle, the main rope is double use, the auxiliary rope is single use, generally speaking, the length of about 40-45 meters.

2. The hook and loop is a metal ring with a spring-loaded opening on one side, which can be used in a wide range of applications. It has considerable strength in the longitudinal direction, but because the opening is weak, it should never be used in the transverse direction.

3, chisel nails chisel nails are used to drive into the cracks of the rock to subsidize the firmness of the climbing tools, in general, depending on the type of rock and choose a different length and thickness of the chisel nails. Nut rope is used to clip into the rock cracks as a fulcrum tool.

4. Screws are tools used to drive chisel holes into uncracked rock, with a wedge attached to the tip. A hammer is a tool used to pound chisel nails or to level sharp rocks.

5. Descender is a tool used in conjunction with climbing ropes to help speed up climbing and save time and labor in carrying luggage. The descender is suitable for rope descent without a large slope to rely on. A surety is a useful tool for safe braking, but it is essential that you are very skilled at it.

6, the helmet is used to protect the head, to avoid the head by falling rocks, helmet-shaped cap should be equipped with a belt, so as to avoid the helmet because of the impact and fall off. In addition, once the helmet has been impacted, its strength is significantly reduced, so attention should be paid to the use of the helmet, the use of a considerable amount of time, it is best to update.

7, gloves, best to wear tough gloves when slipping, because the impulse is very strong when slipping, the hand will be due to friction and serious burns, and there are therefore loose hand fall accident.

8, safety belt, safety belt has chest type, parachute type, waist type, etc., the main purpose is to spread the impulse to all parts of the body, and terminate with a situated posture, and protect the weak points of the body.

9, other: powder bag with magnesium carbonate powder, climbing shoes, rock hammer, drill, ring lugs, expansion anchor ladder, rope ladder, hammock, pulley, tool belt, headlamp, survival paper, rock wedge, rock wedge starter, crag hooks, walkie-talkie, road map of the rocky field.

Rock climbing precautions:

1, avoid over-training

When intensive training but no progress, it is time to review the training course is too frequent, in the body has not been given enough time to recover, that is to start the next training. This can lead to a gradual decline in the climber's fitness with each session.

The correct training method is to start the next training session after the body has recovered from the previous one and has reached overcompensation (about 24 to 36 hours), in order to keep the fitness level steady. In addition, the amount of training must be gradually increased in line with the progress of physical fitness, in order to give the body enough stimulation, so that the physical fitness can have long-term progress, and not stagnate in the plateau period.

The first day of training is for the chest and back, the second day is for the shoulders and arms, the third day is for flexibility and aerobic training, and the fourth day is for repeating the cycle of the previous three days. In this way all parts of the body have two days of rest after training, which can avoid overtraining and sports injuries.

Take at least one day off a week. It is necessary to allow some time for the athlete to recover from intense training or for the muscles to regain energy. This can be done by taking a rest day after three days of training, followed by a rest day after six days of training.

2. Pay attention to healthy diet

①The amount of dietary intake during training should take into account the body's needs, especially the need to consider enough carbohydrate supplementation in order to maintain muscle glycogen storage. During intense training, a low intake of carbohydrates will result in a low muscle glycogen content, and it is difficult to train regularly with a low muscle glycogen content.

2) Eat foods with low glycemic index carbohydrates such as apples, oranges, yogurt, and milk before training.

3) Replenish energy as soon as possible after each day's training because there is only a limited amount of time to replenish energy during the training period, and muscle glycogen recovery is strongest in the first hour after training (eat foods with high glycemic index carbohydrates, such as sports drinks, baked potatoes, honey, white rice, and white bread).

④Arrange a proper eating schedule. Try to eat as much as you can during the training period, and don't give up the opportunity to eat because it's inconvenient. If you go to training without breakfast, you should eat food containing high carbohydrates (e.g., fruits, whole wheat bread) at around 9:00 a.m. or 10:00 a.m. after training. If you train in the evening, you should eat a little bit of food around 3:00 or 4:00 p.m., and then eat your regular meal after training.

5Consider using a microwave oven for food preparation. Microwaving does not cause a significant loss of nutrients and saves time. This can be helpful for busy athletes who need to prepare the ideal food. Reduce intake of fried or salty foods. Try preparing foods by steaming or stir-frying. Don't add too much salt to avoid dehydration.

6) Eat more fresh vegetables (especially root vegetables and leafy greens), fruits (especially acidic fruits) and cereals (such as whole bread, beans, brown rice, etc.).

7 Emphasize starchy foods (complex carbohydrates) over sugary foods (simple carbohydrates), and don't rely on too many pastries or sweets for carbohydrates (except in the first hour after training).

8 Do not eat too much meat, the best choice of meat, lean meat or chicken and duck meat, to reduce the intake of meat and increase the complex carbohydrates. Try to eat a meal without meat every day.

9. Make sure you are getting enough water and fresh juices (which are high in vitamins and minerals) in your meals. Never get dehydrated before or during training. The company's goal is to provide a regular supply of water to its customers.

3. Keep a soft body

While training gives you strength, you will usually feel a gradual tightening of the muscles. A stiff body will limit the ability to move and counteract the effects of muscle building. So don't overlook the importance of flexibility training during your physical training.

The term "flexibility" refers to the range of motion of a limb around a joint. For climbers, good flexibility not only helps with movements such as high kicks and arm crossings, but also keeps the center of gravity close to the wall to save energy or lowers the center of gravity to change the direction of force at the hand points, and prevents injuries from occurring.

The way to improve flexibility is to "stretch" to increase muscle length. Before stretching, it is important to do a complete warm-up exercise in order to achieve the effect and avoid straining. The best time to stretch is after climbing or exercising. Although mild stretching before climbing can help warm up the muscles, over-stretching can impair the muscle's motor response and affect climbing performance.
