195. Thrilling rock climbing training

Rock climbing is a sport full of adventure. The tension and excitement generated when one is climbing tenaciously on the bare rock wall alone attracts many brave people.Although rock climbing started late in our country, it has become more and more popular in a short period of time.

Rock climbing is the same as other sports, not only to master all kinds of skills, but also to carry out arduous special physical fitness training, and especially to have a good psychological quality of calmness and calmness.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, Encore and the others had rock climbing training.When the team assembled in front of the climbing wall, Niu Feihu began to give them a theoretical explanation: "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 rock wall Based on the different fulcrums above, the force during rock climbing can be roughly summarized into the following aspects.”

After Niu Feihu talked about the strength points of the fixed climbing method, he said: "When you climb a rocky cliff, your body should be relaxed naturally, and the center of gravity of the body should be stabilized with three fulcrums, and the center of gravity should move with the transformation of climbing movements. The key to stability, balance, and labor-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. If you get too close, it will affect the observation of rock climbing routes and the selection of fulcrums.

But stick very close when climbing artificial rock walls.When climbing on a natural rock wall, the upper and lower limbs should be coordinated and stretched, the climbing should be rhythmic, and the pulling up and down climbing should be done simultaneously. The center of gravity of the body must fall on the feet, and maintain a climbing posture facing the rock wall and standing upright on the rock wall.The hand is the key to grasp the fulcrum and maintain the balance of the body during climbing. The strength of the arm directly affects the quality and effect of climbing.

Therefore, for beginners, when they are not good at making full use of the strength of the lower limbs, the movement of the hand wall is even more important.The situation is different when climbing artificial rock walls and natural rock walls, and the strength of the arms is also different.The former requires the first knuckles to tighten the fulcrum, while the wrist should be tense, the palm should be attached to the rock wall, and the forearm should be drooping as the palm is close to the rock wall. During the pull-up, the fingers should press down and lift the arm , its action law is that the trajectory of the center of gravity does not change much, and the rhythm is more obvious.However, when climbing a natural rock wall, its movements vary greatly, and various force methods must be used according to different fulcrums, such as grasping, holding, hanging, digging, picking, pinching, pulling, pushing, and supporting. "

After Niu Feihu finished explaining this series of theories, he began to demonstrate.I saw him standing in front of a climbing wall more than ten meters high, grasping the raised part of the rock on the rock wall with his left hand, grasping the edges and corners of the rock face with his right fingers, sticking his forearm to the rock face, pulling down hard to make his body climb up. pedal.Then insert your fingers into a crack on the rock wall, use your fingers hard, and use the strength of your hands, palms, and arms to move your body upwards.

After completing these actions, Niu Feihu said to the team members: "If your arm strength cannot keep up at this time, you should use the pedaling force on the inside of the sole of your foot or your toes to support your body to reduce the load on your upper limbs; Use the toes or heels to hang on the protrusions or depressions of the rock surface to maintain body balance or move the body; or use the larger fulcrum of the front part of the foot to move the body to reduce the load on the upper limbs."

After finishing these few words, Niu Feihu moved up quickly with his hands and feet.I saw that he was as nimble as an ape, his body turned from left to right, from front to left and then to the right. After a while, he climbed to the highest point on the climbing wall more than ten meters high, and then quickly descended to the ground. The players started practicing.

In order to ensure the safety of the team members, this practice is still in a team of two. When one team member climbs upwards, the other team member will go around the highest point on the climbing wall and tie the climbing team member to that climbing team member. After the team member climbs two or three meters, tie the safety rope on the pull ring behind the climbing wall to prevent the climbing team member from falling to the ground in case of falling.

This time Encore and Wu Sainan are still in the same group, and Wu Sainan goes first.When she climbed up, she forgot that her knees should not touch the rock wall. As a result, the support of her feet and the balance of her body were affected, and she almost didn't fall off the rock wall. With similar mistakes, she quickly mastered the rock-climbing skills, and then she climbed more smoothly, and climbed to the highest point of the rock-climbing wall in a short while.

One of the biggest advantages of Encore is that it will always pay attention to its own or other people's mistakes, sum up experience and lessons from mistakes, and never make similar mistakes again.When climbing, drawing lessons from Wu Sainan, she found that while climbing, she should pay attention to the essentials of the movements of the feet and the coordination of the movements of the whole body while noticing the movements of the fingers.

Therefore, when climbing by herself, her legs are externally rotated, the inner side of her big toe is close to the rock surface, her legs are slightly bent, and she uses the fulcrum to maintain the center of gravity of her body. When the fulcrum of the natural rock wall is different in size and direction, she can use it flexibly. The strength of the hands and feet, constantly changing the support point, let one's body move up continuously with the constant change of the force point.At the beginning, her climbing speed was still very slow, and gradually became faster.

Wu Sainan saw that Anke's hands and feet were nimble, and his movements were coordinated and quickly climbed up. After reaching the highest point, he quickly climbed down again. He couldn't help shaking his head and sighing, "Anke, why do you learn everything so fast? ?”

Anke patted his sore and painful palms, shook his numb fingers, smiled and said, "You're not a slow learner!"

The two of them were talking when they heard a sharp scream. They followed the sound in shock 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. Rapidly falling vertically.Seeing that he was about to fall to the ground and die, he was suddenly lifted up by the safety rope tied to his body, and after hitting the rock wall heavily, he was suspended in the air again. It's swinging back and forth!

It turned out that when the team member had climbed more than half of 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, she kicked her feet suddenly in desperation, trying to use that kick Using the power to make my body bounce up a little, so that my hands can grab a bump on it, but I didn't expect that this is just a taboo for climbing. Not only did I not let my body bounce up, but I also let my body jump He suddenly lost his balance, lost his footing, and suddenly broke away from the rock wall and fell down.

Fortunately, the precautions were taken, and the security work was done well in advance. Although the team member was so frightened that his face was pale, and his three souls and seven souls almost didn't finish the run, he was safe and sound, but his back was hit hard by the rock wall For a moment, it didn't hurt.
