In the valley, there are cliffs on both sides.

Liu Xi fell to his death.
4. According to the position of the protection point, the protection methods are divided into upper protection and lower protection, and only the upper protection method is introduced here. The upper protection method is to set the protection point at the top of the climbing route, which corresponds to the top rope climbing and is suitable for training and beginners to climb. At present, there are several popular operation methods, but the safety is high, and the French protection method is widely used, which is usually called five-step method.
1, specific operation steps: five steps are a cycle (taking the right hand as an example). (1) The palm of the left hand is upward, the palm of the right hand holds the main rope downward, and the left hand pulls the rope upward. (2) Hold the rope in your right hand and bounce it backwards from your chest to the outside of your right thigh. (3) Move the left hand to the top of the right hand and hold the rope with the palm down. (4) Move your right hand to the top of your left hand. (5) Return to the first step.
2. Note: (1) At any time, one hand should hold the rope passing through the descender. (2) When paying off the rope, both hands should be coordinated. (3) Pay off the rope slowly and evenly.
5. The protector keeps giving the rope (or receiving the rope) when the climber rises, and tightens the rope to stop falling when the climber misses. When suddenly falling, the impact is so great that it is difficult to grasp the rope directly. The impact force is mainly offset by the friction between the rope and the iron lock and the descender. Because there is great friction on the protection fulcrum, lighter people can protect heavier people. According to the relative position of protection fulcrum, protection forms are generally divided into the following two types:
Upper protection:
A form of protection where the protection fulcrum is above the climber. In the process of climbing, the protector has been pulling the rope, so that there is no rope left on the climber's chest, but don't pull it too tightly, so as not to affect the climber's action, which should be paid special attention to when climbing high elevation angle. The upper protection has no special requirements for climbers, and the impact force is small and safer when falling. In the following protection, the equipment used generally includes seat belts, iron locks and descenders. When the protector takes up the rope, it should be noted that one hand should always hold the rope behind the descender (or hold the ropes at both ends of the descender together), and it is difficult to stop falling only by holding the rope in front of the descender.
Lower protection:
The protection method that the protection fulcrum is located under the climber. There is no preset protection point on it, just hang the protection rope into the iron lock on the safety fulcrum on the way during the climber's ascent. This is the only feasible protection method for leading climbers, which is practical and stipulated in international competitions. However, this kind of protection requires the climber to hang himself for protection, and it has a long falling distance and strong impact when falling, so it is generally used by skilled people.
Climbing technique
Rock climbing requires good physical conditions, but more importantly, skilled skills. Learning climbing skills is very practical and must be practiced in constant climbing. If you have skilled people to guide you, you will get twice the result with half the effort.
Operation:
The fundamental purpose of freehand rock climbing is to make the body move upward and get close to the rock wall. There are many fulcrum shapes on the rock wall, and there are dozens of common ones. Climbers should be familiar with the shapes of these fulcrums and know where to grasp different fulcrums and how to exert their strength. Finger strength is very important in rock climbing, which can usually be practiced by means of finger lying support, pull-ups, finger hanging pull-ups and lifting heavy objects. At present, some foreign experts have been able to reach the strength level of one-way aerobics. When climbing a long route, you can choose an easy position to take turns to rest. The rest area should be chosen where there is no elevation angle or the elevation angle is small and the fulcrum on the hand is large. When resting, keep your feet firmly on the fulcrum, keep your arms straight (it is difficult to rest when bending over), push your upper body backward, but your waist must be pushed forward, so that your lower body can cling to the rock wall and your weight can be pressed on your feet, reducing the burden on your arms, moving your fingers, shaking your hands to relax, and rubbing some magnesium powder to avoid slipping.
Foot method:
In order to reach a certain level of rock climbing, you must learn to use your legs and feet. Legs have great bearing capacity, explosive force and endurance, so we should make full use of the strength of legs and feet in climbing. Rock climbing usually wears special climbing shoes. The soles of these shoes are hard rubber, the forefoot is slightly thick, the shoe body is tough leather, the toe is pointed, and the sole friction is large. Wearing these shoes can firmly support the weight of your whole body when you step on a fulcrum as narrow as less than one centimeter wide. When buying this kind of shoes, everyone must pay attention to it, and don't buy them too big. As long as you can get in, your big toes are dug in and you can't straighten up. I'm used to it, just like putting oil on my feet. The right foot slides out from the fulcrum and the left foot slides in at the same time. The weight is always borne by the feet, and the hand is only used to adjust the balance. In addition to supporting weight, feet are often used to keep balance during climbing. Your foot doesn't have to step on the fulcrum all the time. Sometimes you have to hang one leg to adjust the position of your body's center of gravity, so that the weight can be stably transferred to the other foot.
Route planning:
Many fulcrums are installed on one side of the rock wall. Choosing different fulcrums can form multiple climbing routes. Everyone has different optimal routes according to their different physical conditions. When practicing, you can first look at other people's climbing routes, choose an optimal route according to your physical condition, exercise your eyesight, and discover and plan new routes. In the official competition, you can't look at other people's routes, you must plan it yourself. This requires a better understanding of your height, arm length, leg height and finger strength. In practice, a rock wall, after it can reach the top, usually has endless use value. You can increase the difficulty by planning different routes, generally consciously limit yourself and give up some fulcrums, such as giving up some big points, deliberately bypassing a key point on the original route, or using only the fulcrums on one side or in the middle of the rock wall, or transitioning from one route to another.
Rock climbing is a fascinating sport. Few people like it now, but they all come together because of the same hobby. Walking into this small circle, you will find that people here are friendly and willing to help each other. They protect each other, learn from each other, are willing to give advice to new laptops, and will also argue over some technical issues. The best way to learn rock climbing is to join them and share their happiness. People are completely free on the rock wall, which will only bind your physical strength and imagination. To practice, to experience the dancing charm.
6. Increase the flexibility and coordination of the body. Coordinationofmindandbody): This is the key ability of rock climbing, which is more important than physical strength; Foreign medical institutions have used rock climbing to correct children's muscle development and coordinate training of hands, eyes and body.
Strength: Rock climbing needs a balance of strength and beauty, and it is enough to bear its own weight and defying gravity. In this matter, girls are no worse than boys.
Concentration: One can cultivate one's concentration on things by stepping on the rocks with full attention and paying attention to every detail of the body's displacement on the rocks.
Initiative: When you climb a rope to bear the weight and "hang" on a high rock wall or tower, do you give up or continue to insist? What can be described is not only courage, but also willpower, sense of honor and determination to surpass oneself.
Self-confidence: In the face of a rock field that is at least 3 or 4 times higher than yourself, to overcome it, the mind is naturally more self-respecting and confident than ordinary people.
Balance: Known as the "Spider-Man" walking on the rock wall, the basic posture of walking is "three-point movement", relying on a sense of balance!
