Causes and Treatments of Hand Fatigue Caused by Rock Climbing
It is easy to cause local fatigue of the limb during climbing exercise, especially in the hand. How to quickly recover the fatigue of the athlete's hand is an urgent problem to be solved. This article summarizes the causes and treatment methods of hand fatigue in rock climbing for reference by rock climbers.
1. Characteristics of the project of climbing The climbing can be divided into speed rock climbing, difficulty rock climbing and climbing stone according to the nature of the competition. According to the sports venue, it is divided into artificial site rock climbing and natural site rock climbing. But no matter what kind of rock climbing, athletes' physical requirements are very high, especially the strength. As far as the technology itself is concerned, climbing projects require climbers to climb upwards on pre-designed routes. During the climbing process, the completion of each movement must rely on the force of muscle contraction to overcome its own gravity and External resistance and centrifugal force.
For the climber, he uses the “three-point fixing method†of hands and feet as the basic climbing tactics, using the pull, buckle, support, gripping, pinching, pushing and other actions of the upper and lower limbs, and the synthesis of other parts of the body. Power to complete. In general, during the entire climb, the climber spends most of his time pulling, grasping, deducting, pinching, hanging, and supporting his fingers to support the entire body weight. The load on the hand is far greater than other parts. At the same time, the hand muscles are small, the area is small, and the capillary blood vessels are not rich in distribution. Therefore, the special strength of the hand requires high quality, and the muscles and joints of the hand are also more It is prone to exercise fatigue. Fatigue symptoms can be seen in the hand muscles, tendon Swelling tight, according to the pain, joint stiffness, smaller activity, long-term climbing can cause fingertip hypertrophy.
2. Energy supply characteristics of rock climbing The speed climbing requires athletes to complete the required two routes in the shortest possible time. Generally, it takes only a dozen seconds for a line of men's athletes; women only need more than twenty seconds to finish, so the players are in the game. The energy comes mainly from the phospho-gen system. Rock climbing athletes need to exert force quickly during the climbing process, and the required exercise intensity is relatively large. The content of ATP and CP in muscles will rapidly drop, resulting in fatigue at the site of use.
Difficult climbing is the protection of the tether under the athlete, with a rope to climb upwards, and in accordance with the rules of the game, the middle protection padlock will be put in order. The final height of the climb will determine the position of the athlete in each round. It takes a long time to play, so the athlete's endurance requirements are relatively high. The muscles of the hands often work in the absence of oxygen. The longer the duration of work, the more lactic acid will be produced, and the more fatigue the part will become.
Rock climbing is a type of project where the requirements of the opponent's power quality are relatively high. The hand is also the most likely to produce exercise fatigue. It is also very important for rock climbing athletes to recover from fatigue, through massage, external use of traditional Chinese medicine, instrument therapy, acupuncture, nutrition In order to achieve better results, different methods may be used to solve the problem of hand fatigue in combination with several methods to provide useful help for rock climbers to restore their athletic ability and improve their performance. However, research on the recovery of hand fatigue for rock climbers is still rare and needs to be strengthened.
