Rock climbing is a sport full of adventure. The tension and excitement generated when a person climbs up on a bare rock wall tenaciously attracts many brave people. Although rock climbing started late in our country,
But in a short period of time, this sport has become more and more popular.
Rock climbing, like other sports, requires not only the mastery of various skills, but also arduous special physical training, and especially the good psychological quality of being calm and calm. In view of these characteristics of rock climbing and its own needs,
This sport has become an indispensable training subject for SWAT teams and special forces.
This afternoon, Anke and the others conducted rock climbing training. After the team gathered in front of the climbing wall, Niu Feihu began to explain the theory to them: "In the process of rock climbing, the most basic technique is the fulcrum fixed climbing method.
.As far as this basic technique is concerned, combined with the different fulcrum conditions on the rock wall, the force used in the rock climbing process can be roughly summarized into the following aspects."
After Niu Feihu explained the force points of the fixed climbing method, he added: "When climbing a rocky cliff, your body should naturally relax, and the center of gravity of the body should be stabilized with three fulcrums, and the center of gravity should move with the change of climbing movements. This is whether rock climbing can
The key to stability, balance, and effort saving. If you want to relax your body, you must keep a certain distance between your body and the rock wall according to the steepness and gentleness of the rock wall. Getting too close will affect your observation of the climbing route and the selection of fulcrums.
But when climbing an artificial rock wall, you need to stay very close. When climbing a natural rock wall, your upper and lower limbs must be stretched in a coordinated manner, and you must climb in a rhythm. You must pull up and down at the same time, and your body's center of gravity must be on your feet.
Maintain an upright climbing posture facing the rock wall. The hands are the key to grasping the fulcrum and maintaining body balance during climbing. The strength of the arms directly affects the quality and effect of climbing.
Therefore, for beginners, if they are not good at making full use of the strength of their lower limbs, the movements of the hand wall are even more important. The situation is different when climbing artificial rock walls and climbing natural rock walls, and the force exerted by the arms is also different. In the former, the strength of the arms is also different.
While the first knuckle is required to pinch the fulcrum tightly, the wrist should be tense, the palm should be pressed against the rock wall, and the forearm should also droop with the palm close to the rock wall. During pull-ups, the fingers should press down and lift the arm.
The movement pattern is that the movement trajectory of the center of gravity changes little, and the rhythm is more obvious. However, when climbing a natural rock wall, its movement changes greatly. Various force methods must be used according to different fulcrums, such as grabbing, holding, hanging, digging, and scraping.
, pinch, pull, push, hold, etc.”
After Niu Feihu finished explaining this series of theories, he began to demonstrate. He stood in front of the climbing wall more than ten meters high, grabbed the convex part of the rock on the rock wall with his left hand, and dug his fingers on the rock surface with his right hand.
At the edge of the rock wall, place your forearms against the rock surface, pull down hard to push your body up. Then insert your fingers into a crack in the rock wall, use your fingers to exert force, and use the strength of your hands, palms and arms to move your body upwards.
After completing these movements, Niu Feihu said to the team members: "If your arm strength cannot keep up at this time, you must use the inner side of the sole of the foot or the pedaling force of the toes to support the body to reduce the load on the upper limbs; you can also
Use your toes or heels to hang on the protrusions or depressions on the rock surface to maintain balance or move the body; or use the front of the foot to step down on a larger fulcrum to move the body to reduce the load on the upper limbs."
After saying these words, Niu Feihu quickly moved up with his hands and feet. He was as agile as an ape, his body moved left and right, left and right, and in a short while, he climbed to a height of more than ten meters.
Climbing to the highest point on the wall, and then quickly descending to the ground, the team members were then asked to start practicing.
In order to ensure the safety of the team members, this exercise still uses a team of two people. When one team member climbs up, the other team member will tie the climbing team member around the highest point on the rock climbing wall and tie it to the climbing team member.
After the team member climbs two or three meters, tie the safety rope to the pull ring behind the rock climbing wall to prevent the climbing team member from falling to the ground if he falls.
This time Enke and Wu Sainan were still in a group, and Wu Sainan went up first. When she climbed up, she forgot that her knees were not allowed to touch the rock wall. As a result, her foot support and body balance were affected, and she almost failed to climb up the rock wall.
She fell off, but thanks to Enke's timely reminder, Wu Sainan avoided making similar mistakes again, and quickly mastered the rock climbing skills. Then she climbed relatively smoothly, and soon she reached the highest point of the rock climbing wall.
One of the biggest advantages of Encore is that she always pays attention to her own or other people's mistakes, learns from the mistakes, and never makes similar mistakes again. When climbing, she learned from Wu Sainan's lesson. She found that when climbing, she noticed the movements of her fingers.
At the same time, you should also pay attention to the essentials of foot movements and the coordination of body movements.
Therefore, when climbing by herself, she rotates her legs externally, puts the inside of her big toe close to the rock surface, bends her legs slightly, and uses the fulcrum with her feet to maintain the center of gravity of her body. She uses it flexibly when the fulcrums on the natural rock wall are of different sizes and directions.
With the strength of her hands and feet, she constantly changes the points of support, allowing her body to move upwards as the point of focus continues to change. At the beginning, her climbing speed was very slow, and gradually she became
Get up quickly.
Wu Sainan looked at Anke's quick hands and feet, and quickly climbed up in a coordinated manner. After reaching the highest point, he quickly climbed down again. He couldn't help but shake his head and sighed: "Anke, why do you learn everything so fast?
?”
Enke patted his sore and sore palms, shook his numb fingers, smiled and said, "You are not slow to learn!"
The two people were talking when they suddenly heard a sharp scream. They looked frightened and followed the sound, and saw a team member who had climbed to a height of seven or eight meters leaving the rock wall with his hands and feet.
He quickly fell vertically downwards. He was about to fall to the ground and die, but he was suddenly lifted up by the safety rope tied to his body, and he hit the rock wall hard.
After a while, it was hanging in mid-air and swaying back and forth again!
It turned out that when the team member climbed more than half the distance, all the strength in her hands and feet had been exhausted. Seeing that she was about to reach the top after climbing a few meters more, she was in a hurry and kicked her feet violently, trying to use that kick.
He used the force to make his body bounce up a little, so that his hand could grasp a bump on it. However, he didn't expect that this would violate the taboo of climbing. Not only did his body not bounce up, but his body also bounced up.
The child lost his balance, his footing was unstable, and he suddenly broke away from the rock wall and fell downwards.
Fortunately, preparations were made and the safety work was done well in advance. Although the team member turned pale with fright and almost didn't finish the run, there was a near miss, but his back was hit hard by the rock wall.
