Free hand climbing is a kind of outdoor extreme sports which does not rely on any external forces, but only rely on their own strength to complete the climbing process. The rock climbing originated in Europe and is very dangerous. It is listed as the top ten most dangerous sports in the world. This sport only uses natural handles such as cracks, caves and protrusions on the rock, so it has high requirements for rock climbing skills, and it is also a great test for psychological quality. There is only one consequence of any slip in the process of rock climbing: falling freely from high altitude. Therefore, before climbing to choose a good climbing route, to avoid scratches. Unarmed rock climbing combines fitness, entertainment and competition. It is called "ballet on the cliff" by rock climbing fans all over the world.
Three point fixation is the basic method of rock climbing, the main point is: there are certain requirements for the postures and movements of all parts of the body.
Body posture when climbing rock cliff, the body should relax naturally, stabilize the body center of gravity with three fulcrums, and the center of gravity should move with the change of climbing movement, which is the key to the stability, balance and labor saving of rock climbing. If you want to relax, you should keep a certain distance between your body and the cliff according to the steepness of the cliff. If you are too close to the cliff, it will affect the observation of the climbing route and the selection of the fulcrum. But when climbing the artificial rock wall, it should be very close. When climbing the natural rock wall, the upper and lower limbs should stretch out harmoniously, the eyes should be rhythmic, the upward and downward climbing should be forced at the same time, the body center of gravity must fall on the feet, and the climbing posture of facing the rock wall, three-point fixed support, standing on the rock wall, three-point fixed support and standing on the rock wall should be maintained.
Arm movements
The hand is the key to grasp the fulcrum and maintain the balance of the body in climbing, and the strength of the arm directly affects the strength of the body
The quality and effect of unarmed climbing. Therefore, an excellent rock climber must have enough finger strength, wrist strength and arm strength. For beginners, when they are not good at making full use of the strength of their lower limbs, arm movements are more important. How to apply force to the arm is different between artificial rock climbing and natural rock climbing. The former requires the first finger joint to tighten the fulcrum, the wrist to be tight, the palm to stick to the rock wall, and the forearm to droop with the palm close to the rock wall. In the pull-up, the fingers (grip) have the action of pressing down and lifting the arm. The movement rule is that the trajectory of the center of gravity changes little, and the rhythm is more stable Obviously. But when climbing the natural rock wall, its movement changes greatly. According to the different fulcrum, we should use all kinds of force methods, such as grasping, grasping, hanging, picking, raking, pinching, pulling, pushing, supporting, etc.
Foot movements
The key to a good climber's climbing skill is whether he can make full use of his legs. Climbing by arm strength alone cannot last. The crux of the foot movement is to turn the legs outward, keep the inside of the big toe close to the rock surface, bend the legs slightly, and keep the body center of gravity by stepping on the fulcrum. In the case of different sizes and directions of the fulcrum on the natural rock wall, it should be used flexibly. But remember, do not touch the knee rock surface, otherwise it will affect the foot support and body balance, and even cause slippage and knee injury. In addition, when stepping on the fulcrum with the foot, do not use too much force, and grasp the direction of force.
arm-leg relationship
The strength of upper and lower limbs of excellent rock climbers is used in coordination. For beginners or unskilled athletes, upper limb strength is more important. When climbing, it is often the upper limb pull-up and the lower limb push and lift to move the body. If the upper limb strength is poor, it is easy to get tired when climbing, which is manifested as arm weakness, pain and numbness, and gradually losing the ability to grasp. After losing grasping ability, it is difficult to maintain body balance even with good lower limb strength. Therefore, to learn rock climbing, first of all, you need to practice the strength of the upper limbs. The upper limbs should mainly rely on the strength of the fingers, wrists and arms, and then cooperate with the strength of the wrists, toes and legs, so that the body center of gravity can move harmoniously with the different directions of force, and the coordination of hand and foot movements will be free.
