Rock climbing can easily lead to localized fatigue in the limbs, especially in the hands. How to quickly restore hand fatigue in athletes is an urgent issue to address. This article summarizes the causes and treatment methods of hand fatigue in rock climbing for the reference of climbing enthusiasts.
Steps/Methods
Massage can effectively relieve muscle tension and spasms, as it enables passive movement of muscle fibers, relaxing the stretched muscles, eliminating fatigue. The expansion of muscle capillaries and the opening of reserve capillaries lead to accelerated blood circulation, which promptly supplies the oxygen and nutrients needed by the muscles, enhances the activity of nerves, muscles, and organs, and promotes the absorption and excretion of metabolic by-products such as lactic acid. Thus, it helps improve work efficiency and eliminate fatigue. Hand massage is generally performed during or after training, typically lasting no more than 10–20 minutes. The treatment focuses on promoting blood circulation, resolving stasis, and relaxing tendons and meridians. Since there are relatively few hand muscles, techniques involving large movements such as grasping or rolling are not suitable. Methods such as kneading, wiping, pinching, lifting, stroking, and traction (a type of friction or joint movement technique) are usually preferred. Sun Hepu found through experiments on localized muscle tissue in rats that the pinching technique significantly delays fatigue, prolongs working time, and accelerates the recovery from exercise-induced fatigue.
External Herbal Application External herbal remedies can be applied through soaking or direct application. Herbal soaking utilizes the heat stimulation of water to dilate blood vessels, reduce peripheral resistance, increase blood flow and speed, and promote better circulation of both blood and lymph in the hands. At the same time, the expansion of pores allows for faster absorption of active herbal components, enhancing the excretory functions of sweat and sebaceous glands, and swiftly eliminating harmful substances (such as urea nitrogen) and fatigue-inducing agents (like lactic acid) from the body. Herbal soaking is usually done before resting at night, with a soaking duration of about 20–30 minutes, maintaining the water temperature around 50°C to achieve ideal results. In this area of research, Zhao Xin et al. used traditional Chinese herbal soaking solutions to treat patients with hand swelling. Comparative findings showed that the herbal soaking group experienced improvements in reducing swelling and joint mobility, and also significantly outperformed the placebo group in pain relief.
Direct application of herbs allows the medication to penetrate the skin and reach the deeper areas where fatigue and pain originate. This method is notably effective in alleviating local muscle fiber spasms, improving microcirculation, and reducing muscle stiffness and soreness. Typically, the herbs are ground into powder, placed on paper with an area corresponding to the size of the hand and a thickness of about 0.5 cm, heated, and then applied to the affected area. Commonly used external herbs include ephedra, cassia twig, ledebouriella root, notopterygium root, and angelica dahurica (which dispel wind-cold), as well as safflower, ligusticum, motherwort, pseudo-ginseng, and turmeric (which resolve stasis). Additional tonifying herbs such as astragalus, codonopsis, angelica sinensis, and rehmannia may be included based on symptoms. Herbal selection should vary depending on the degree of fatigue and the climber’s age.
Physical Therapy Physical therapy uses instruments to apply various physical stimuli to the body, inducing reactions that regulate, promote, maintain, or restore physiological functions, suppress causes, and thereby achieve therapeutic goals. Common treatment methods include electromagnetic waves, ultrashort waves, infrared rays, and warm low-frequency electrical stimulation. These physical energies—heat, electricity, magnetism, light, and sound—applied locally can relieve pain, reduce swelling, improve local blood circulation, and regulate nerve and muscle tension, all of which aid in accelerating the recovery from hand fatigue.
Researchers studying the treatment of muscle adhesions have found that warm low-frequency electrical stimulation is highly effective. The tiny vibrations generated by low-frequency currents serve as an appropriate stimulus that may inhibit or interrupt the transmission of pain signals, thus providing significant analgesic effects. Pulsed modulated current promotes peripheral circulation, eliminates edema, aids in inflammation absorption, relieves muscle spasms, and reduces or eliminates pain. Additionally, low-frequency therapy has a warming effect: it dilates local blood vessels, increases cell permeability, facilitates inflammation absorption, boosts metabolism, and delivers anti-inflammatory and analgesic benefits.
Acupuncture Acupuncture involves using various types of needles on specific acupoints of the body, stimulating “qi” through different methods to adjust bodily functions for disease prevention. Applying acupuncture to the hands can unblock meridians, support healthy energy, dispel pathogens, raise hand temperature, accelerate blood flow, and promote faster metabolism of lactic acid.
Hand fatigue may also lead to decreased muscle strength. Using filiform needles to stimulate hand muscles can effectively restore muscle strength. The mechanism may involve enhanced function of the neurotransmitter release system due to needling, increasing overall excitation and shifting the body from a normal to a stress-responsive state. This mobilizes various bodily reserves: red blood cell and hemoglobin levels rise, glycogen synthesis in muscles accelerates, and the activity of various enzymes required for gluconeogenesis increases. These changes collectively restore muscle strength to a higher level.
Commonly used acupuncture points include Shaoshang, Shangyang, Zhongchong, Guanchong, Shaochong, Shaoze, Hegu, Shousanli, Quchi, Zusanli, Waiguan, and Ashi points. Filiform needles are generally used with balanced reinforcing-reducing or strong reinforcing-reducing techniques. Niu Dong conducted a study on an overexertion exercise group where needles were rapidly inserted into the subcutaneous layer and then directed toward nerve pathways, employing large lifting-thrusting motions with slight directional changes under the skin until the subject experienced a strong electric shock-like or sore-numb sensation radiating to the extremities—then the needles were withdrawn. Results showed this method could accelerate the clearance rate of blood lactic acid.
Nutrition Rock climbing demands high levels of hand strength, so daily diets should be rich in protein to facilitate the recovery from exercise-induced fatigue. Protein intake should reach 2g per kg of body weight, with one-third being high-quality protein. However, excessive protein can disrupt the body's acid-base balance, lead to calcium loss, and increase the burden on the liver and kidneys.
The diet should also contain ample electrolytes such as potassium, sodium, calcium, and magnesium. Additionally, climbers should ensure sufficient intake of vitamin B and citric acid, both of which help clear excess lactic acid produced in the limbs. Zhang Li’s research on mulberry vinegar containing citric acid found that the substance effectively reduced lactic acid levels in mice, producing an anti-fatigue effect.
Precautions
Rock climbing is an activity that demands considerable hand strength, making the hands particularly prone to sports-related fatigue. Therefore, recovering hand fatigue is especially important for climbers. A combination of methods—including massage, external herbal applications, physical therapy, acupuncture, and proper nutrition—can sometimes yield better results in addressing hand fatigue. These approaches help climbers regain their performance abilities more quickly and improve athletic performance. However, research on the recovery of hand fatigue in rock climbers remains limited, indicating a need for further study in this area.
