1. Indoor climbing skills: make good use of spring action
In order to obtain more jumping force, before each dynamic action, you should first move in the vertical direction, first up and then down, and extend and compress like a spring. This force will allow you to reach the target rock point to the maximum extent. If there is not enough space for spring action, you can also rely on swinging your body to gain momentum.
2. Grip and open grip of indoor climbing skills
When fingers grasp a convex or concave edge of the fulcrum, they will generally cling to it. But in many cases, some fulcrums can be grasped with the palm of the hand, without relying on the strength of the fingers alone, and the grasping of the whole palm can also increase the stability of grasping. If the edge of the fulcrum or the small hole at some points can support the second joint of the finger, the hand can lean flat on the rock surface, so that the hand can be opened and the fingers can be brought together, so that the finger can fully contact with the fulcrum, and the whole palm does not need to hold the fulcrum tightly. In this action, the thumb generally plays a small role, but if the fulcrum is inclined, the thumb can pinch the point with other fingers.
3. Foot movements of indoor climbing skills
The key to an excellent climber’s climbing skills is whether the strength of his legs can be fully utilized. Climbing by arms alone cannot last. The main points of foot movements are that the legs rotate outward, the inner side of the big toe is close to the rock surface, the legs bend slightly, and the foot is used as the fulcrum to maintain the center of gravity of the body. In the case of different sizes and directions of the fulcrums of natural rock walls, they should be flexibly used.
4. Hand foot cooperation in indoor rock climbing
All excellent rock climbers use their upper and lower limbs in coordination. For beginners or unskilled athletes, the strength of upper limbs is more important. When climbing, the upper limbs often pull in and the lower limbs push and lift to move the body.
If the strength of the upper limbs is poor, it is easy to get tired when climbing, which is manifested as weakness, pain and numbness of the arms, and gradually lose the ability to grasp. After losing the grip ability, even with good lower limb strength, it is difficult to maintain physical balance. Therefore, to learn rock climbing, we should first practice the strength of the upper limbs, which should be mainly based on the strength of fingers, wrists and arms, and then be combined with the strength of ankles, toes and legs, so that the center of gravity of the body moves harmoniously with the direction of force, and the coordination of hand and foot movements will be free.
Characteristics of indoor rock climbing
1. Compared with outdoor climbing, the safety factor of indoor climbing is greatly improved, and protective equipment such as ropes, iron ropes and hooks are provided. Participants used the three-point fixation method to climb up along the edges, fulcrums and cracks of the rock wall. People mainly compared the difficulty, speed and skill of climbing.
2. Indoor climbing seems easy but sometimes difficult. It is required that players integrate endurance, flexibility and balance ability, and use fulcrums with different difficulties to complete difficult movements such as cross-over, pull-over, and so on, so as to get stimulation and enjoyment from adventure. If you make a bold effort to climb up, you will surely suffer.
Indoor climbing requires essentials and dexterity. Beginners are generally advised to find large and easy to grasp rock points to climb up, and then choose small rock points to increase difficulty and exercise arm strength after slowly mastering some skills.
3. Don’t think that climbing is only a man’s patent. Many girls can also be seen in the climbing hall. Whenever a girl climbs bravely on the cliff under the protection of a protective rope, the onlookers always keep cheering. The rock climbing coach warned that when climbing, the body should be as close to the rock wall as possible, so as to save energy. The foot should step on the dimple on the rock point, which can effectively prevent slipping.
Types of indoor climbing
1. Drilling lock rock climbing field
It is a rock field type with simple construction method and low cost at present. As long as the hole is drilled on the concrete wall according to the standard technical specifications, the expansion anchor pile is driven and the rock is locked. However, if the height increases, the construction difficulty will be relatively increased, which is not necessarily cheaper. The disadvantage is that the rock points can only protrude outward but not inward, and the route changes less and monotonously.
2. Wood plywood rock wall
This kind of artificial rock field is made of hot-pressed wood plywood, coated with a layer of polyester condensate on the outside, that is, most of them are replaced with paint in China, and the back is supported by metal steel frames. Because it is composed of wood plywood, its cost is higher than that of rock field in the form of hole locking rock block, but the relative variation of rock surface is also relatively rich.
3. Plane synthetic slate wall
This kind of rock field is composed of unit rock plates. The basic material of synthetic rock plate is glass fiber reinforced polyester. Because through simple modular combination, both simple and complex designs can be assembled like building blocks, making it the best rock field material in the world at present, whether it is tactile or simulates three-dimensional changes.
