Techniques for the use of various different rock climbing techniques

 　　Some people think that hands can bear more weight for climbers, so the hand points must be large. However, this is unnecessary. Most of the hands on the straight wall are used to master balance. The contact force between the fulcrum and the hand will become the key. But no matter what, do not use too much force on the hand when grasping the point. On the contrary, the hand should be relaxed and use the minimum force to grasp the point, otherwise the arm strength will be lost quickly. There are many shapes of fulcrum on the rock wall, and there are dozens of common types. Climbers should be familiar with the shapes of these fulcrums and know where and how to grasp the hands of different fulcrums. According to the position and direction of the protruding and sagging on the fulcrum, there are mainly the following climbing techniques:

      Holding

　　When your fingers grasp a concave edge of the fulcrum, you usually hold it tightly. But in many cases, some fulcrum can be grasped with your palm without relying solely on the strength of your fingers. Moreover, the grasping of the entire palm can also increase the stability of the grasp.

　　Open grip

　　If the edge of the fulcrum or a small hole at some points can support the second joint of the finger, the hand can be flat on the rock surface. In this way, the hand can be opened and the fingers are brought together to fully contact the fulcrum, so that the entire palm does not need to hold the fulcrum tightly. In this action, the effect of the thumb is generally small, but if the fulcrum is tilted, the thumb can pinch the point with other fingers. Generally speaking, if the fulcrum is round, the method of opening and grip is the best choice.

　　Sharpening

　　When the hand encounters a relatively small fulcrum When the four fingers of the hand can be put together, you can press the index finger with your thumb and hold the fulcrum to perform a clamping action. When doing clamping, avoid unnecessary pressure and tension to avoid injury to the fingers [When the palm is facing upward and grabbing the point of soil, you need to use a reverse clamping action. This clamping action is often used to maintain balance. It is achieved through the reaction force between the hands and hands or between the hands and feet

　　Curved grip

　　Curved grip is to bend the palm, close the four fingers together, press the thumb on the index finger, and grasp the fulcrum on the outer edge of the palm. Because the force joint of the thumb is very strong, it can control the hand shape well. Therefore, this grip is not only powerful, but also gives the other fingers a good opportunity to relax. In fact, the forearm can be relaxed by bending the wrist and holding the fulcrum, so this kind of clamping action of the wrist is a good rest position, usually in small This kind of action is used more frequently.

Pinching and gripping

When the shape of a fulcrum has no side to hold and can only rely on the friction of the fingers, you need to use the action of pinching. Generally speaking, the direction of pinching the thumb is opposite to the direction of fingers, but sometimes, some pinchable points can make your thumb press on the edge of the fulcrum, and the direction of its pressing is always the force of the four fingers.

　　Side pulling

　　The basic technical point of side pulling is to make the body side to the rock wall, with the opposite side of the body contacting the rock wall, and the other leg is stretched straight to adjust the body balance, push the body up with the force of a single leg, and grasp a fulcrum above. This action is mainly used by large sites when the over-elevation area and the sand point is arranged close to a straight line.

　　"Caval point" method

　　On natural rock walls, you can often find that the rock walls have Many small holes, and modern rock climbing competitions often have many "hole points". The size of the climbing hole points ranges from a narrow slit to a large hole point that can be reached into one or two fingers. When grasping these hole points, first feel the situation in the hole from the inside and find the deepest part to grasp. Pointing among all hole points is the most difficult. If you accidentally pull the muscle keys of the fingers. If the single finger point is in a sag direction, you can lean on the index finger to increase the stability of the grasping point. The shape and size of the hand point are different. There may be multiple grasping methods for the same fulcrum point, but to quickly choose the best method, you also need to master it through a lot of exercises to master it and use it flexibly. In the use of climbing techniques, the strength of the finger is very important. Usually, you can practice by burping your fingers, pulling up your fingers, lifting and pinching heavy objects.
