Chapter 717·Theory and Practice Collide

"Rock climbing has the reputation of 'rock ballet' and 'rhythmic gymnastics on the cliff'. It was originally derived from mountaineering. It is very skillful and adventurous. It is an important item in extreme sports. Very popular in the world.

You don’t need to use tools when climbing rocks. Of course, what I’m talking about is free climbing. When climbing upwards, you only move upwards with the balance of your hands, feet and body. The hands and arms should use various force methods according to the different fulcrums. , such as grasping, holding, hanging, pulling, supporting, pushing, pressing, etc., so this sport requires relatively high strength and body flexibility requirements for climbers.

Normally, in addition to free climbing, you need to fasten safety belts and protection ropes, and equip ropes to avoid danger. However, some people who really like to challenge the limit and seek excitement generally use free climbing, that is to say, they do not If safety measures are needed, the cliff we need to climb this time is only 20 meters high, so there is no need to keep safety ropes and the like. "

After roughly educating the people in the live broadcast room about what rock climbing is, Zhang Yang squatted down and rubbed his hands vigorously on the dry ground next to him to increase friction, and then squatted down again to tighten the shoelaces. Tight, after stuffing all the shoelaces that were thrown back and forth into the upper of the shoe, I came to the bottom of the cliff to find a suitable route for climbing up. First of all, it is natural to avoid places that are wet by water, that is, too Pass close to the waterfall, and then look for a route with climbing objects all the way up.

The route is still easy to find. With keen eyes and countless rock climbing skills in his mind, a broad avenue soon appeared in Zhang Yang's mind, and there seemed to be a path woven by bright light from bottom to top on the cliff. And the road map that came out appeared in front of my eyes.

Clapping his hands, turning his head to look at Rhubarb lying there looking at him, Zhang Yang put his hands and feet on the first climbing object...

"Brother Yang, be careful, we understand the theory, but after all, we only climbed once, so we must pay attention to safety!"

"The theory is clear and sound, but you must pay attention to safety. You don't have a safety rope. It's not easy to climb halfway up and think about getting down!"

"I am a rock climbing enthusiast. Anyway, I don't think the anchor can climb up. You don't even have safety measures. You really think you are the master of free climbing."

"That's right, it's as if everything is the same, and you don't even apply chalk, what should you do if your hands are sweating halfway through crawling?"

"To those fans who are fans of anchors, let me explain why you need to use magnesium powder. When climbing rocks, your hands will definitely sweat. Magnesium powder can absorb moisture and increase the friction between your hands and the surface of the rock mass to prevent slipping."

"That's right, I don't like those stupid fans who don't understand anything and just blow it up, making it look like your anchor or something."

"In addition to the moisture absorption function mentioned by the brother upstairs, the magnesium powder can also fill in the folds of the palm, increase the contact surface with the rock mass, make the grip more solid and uniform, easy to control, and move more freely."

"I wonder if you people are weird? Didn't you see that Brother Yang just rubbed dirt off the ground? Who would have known that this time he came here for rock climbing and brought the magnesium powder you mentioned?"

The cliff wall of about 20 meters is actually not a challenge for Zhang Yang at all. What kind of magnesium powder is not, and if he is allowed to use this kind of thing at this height, it is better to just use tools to climb up.

He came to the position more than five meters above the ground with ease, and the fans in the live broadcast room were surprised that this guy actually climbed up while acting as a commentator.

"There is a basic method of rock climbing, that is, the three-point fixation method, which has certain requirements for the posture and movement of each part of the body.

First of all, everyone must pay attention, people who are afraid of heights should not even think about doing this sport, because you must keep your body relaxed when climbing rocks, because this sport still requires relatively high body posture. We need to stabilize the center of gravity of the body with three fulcrums, and the center of gravity must move with the transition of climbing movements. This is the key to whether rock climbing can be stable, balanced, and labor-saving. "

While talking about Zhang Yang, he kept a certain distance between his body and the rock wall according to the steepness of the rock wall. By the way, he stretched out his arms as much as possible, and tightly grasped the two protrusions he just found with both hands. starting point.

"Here we want to remind you that if you are using the artificial rock wall for indoor rock climbing, your body should be very close to the rock wall, but if it is this kind of natural rock wall, you have to rely on the steepness of the rock wall. Keep a certain distance between the body and the rock wall, because if you get too close, it will affect the observation of the climbing route and the selection of the fulcrum.

When climbing on a natural rock wall like now, the upper and lower limbs must be coordinated and stretched like I am now, and the rhythm must be controlled. The pull-up of the arms and the descent of the feet must be vigorous at the same time, and the center of gravity of the body must fall on the feet. , keep facing the rock wall to form a three-point fixed support. "

After doing the same thing as he said just now and climbing up two or three meters, Zhang Yang reckoned that someone could understand, then Zhang Yang continued to talk about the essentials.

"Hands are the key to grasping the fulcrum and maintaining body balance during climbing, and the strength of the arm directly affects the quality and effect of climbing. Therefore, an excellent rock climber must have sufficient finger strength, wrist strength and arm strength.

Of course, for beginners, arm movements are even more important when they are not good at making full use of lower body strength.

Whether the climbing technique is good or bad, the key point is whether the strength of the legs can be fully utilized, because it is impossible to climb with only the strength of the arms.

The main point of foot movement is to rotate the legs outward, keep the inner side of the big toe close to the rock surface, bend the legs slightly, and use the fulcrum to maintain the center of gravity of the body. When the fulcrum of the natural rock wall is different in size and direction, use it flexibly.

But remember, the knees must never touch the rock face, otherwise even if you hit the rock wall lightly, it will affect the support of the feet and the balance of the body, and even cause slippage and injury to the knees. When holding the fulcrum, avoid using too much force, and grasp the direction of force. "

It's not a performer, Zhang Yang's live broadcast room has always been when encountering something novel, he will explain it to his friends in the live broadcast room in detail, and will continue to remind some precautions.

Often when some fans follow their idols to do some operations, they always feel that they have to do what their idols do, as if this will bring them closer to their idols. If they encounter some irresponsible people wantonly Bragging about the simplicity of this and the ease of that, without reminding of dangerous situations and precautions, the probability of problems is simply not too high.

When he first decided to go rock climbing, Zhang Yang had already considered that if someone really went out into the wild to try it, it would be a big problem, so he kept reminding everyone in the live broadcast room to pay attention to safety, And also try to talk about some action essentials in detail.

Five or six minutes later, when he was less than one meter away from the top of the cliff, Zhang Yang suddenly grabbed a flat and protruding rock, and while the fans in the live broadcast room were stunned, he suddenly turned around and threw He hung himself on that rock, and was still facing the outside of the cliff.
