Causes
1. Characteristics of Rock Climbing Rock climbing can be divided into speed climbing, difficulty climbing, and bouldering by competition type, and into artificial wall climbing and natural rock face climbing by venue. However, all types demand high physical fitness from athletes, especially strength. Technically, rock climbing requires climbers to ascend along pre-designed routes. Each movement relies on muscle contraction to overcome body weight, external resistance, and centrifugal force. Generally, throughout the climb, climbers mostly use their fingers to pull, grab, hook, pinch, hang, and brace to support their entire body weight. The load on the hands far exceeds that on other body parts. Moreover, the hands have fewer muscles, a smaller surface area, and relatively sparse capillary distribution. Therefore, they require high levels of specialized strength, making them more prone to exercise-induced fatigue. Symptoms include soreness, tightness, and tenderness in the hand muscles and tendons, joint stiffness, reduced range of motion, and even finger swelling after prolonged climbing.
2. Energy Supply in Rock Climbing Speed climbing requires athletes to complete two designated routes in the shortest time possible—usually just over ten seconds for men and around twenty seconds for women. Thus, the primary energy source during competition comes from the phosphagen system. As climbers perform rapid, forceful hand movements, the intensity is high, leading to a rapid decline in ATP and CP levels in the muscles, which causes fatigue in the active areas. Difficulty climbing involves athletes climbing upward while roped from below, following a sequence of placing intermediate protection locks as dictated by the rules. The final height reached determines their ranking in each round. These climbs last longer, demanding greater endurance. The hand muscles often work under anaerobic conditions, producing more lactic acid the longer the activity continues, thereby increasing localized fatigue.
Treatments
1. Acupuncture Acupuncture involves using various needles to stimulate specific acupoints on the body, activating “qi” to regulate bodily functions and prevent illness. Stimulating the hands with acupuncture can unblock meridians, support health, and dispel pathogens, raising hand temperature, accelerating blood flow, and promoting faster lactic acid metabolism. Hand fatigue may also reduce muscle strength. Using filiform needles to stimulate hand muscles can effectively restore strength, likely by enhancing neurotransmitter release, increasing overall excitability, shifting the body into a stress-response state, mobilizing reserves such as increased red blood cells and hemoglobin, boosting glycogen synthesis, and elevating the activity of enzymes involved in gluconeogenesis—all of which help restore muscle strength to a higher level. Commonly used acupoints include Shao Shang, Shang Yang, Zhong Chong, Guan Chong, Shao Chong, Shao Ze, He Gu, Shou San Li, Qu Chi, Zu San Li, Wai Guan, and Ashi points. Techniques usually involve balanced tonification and sedation or strong tonification-sedation methods. Niu Dong’s experiment with overexerted subjects involved rapid needle insertion into the subcutaneous layer, followed by directional insertion toward nerve pathways, with large-amplitude lifting-thrusting motions and slight directional changes under the skin until the subject felt strong electric-like or sore sensations radiating to the limbs. This method was found to accelerate lactate clearance.
2. Nutrition Rock climbing demands high hand strength, so a diet rich in protein is essential to aid recovery from exercise fatigue. Protein intake should reach 2g per kg of body weight, with one-third being high-quality protein—but not excessive, to avoid disrupting acid-base balance, calcium loss, or overburdening the liver and kidneys. The diet should also include sufficient electrolytes like potassium, sodium, calcium, and magnesium. Additionally, climbers should consume vitamin B and citric acid, both of which help clear excess local lactic acid. Research by Zhang Li on mulberry vinegar containing citric acid showed it effectively reduced lactic acid in mice, demonstrating anti-fatigue effects.
3. Massage Massage effectively relieves muscle tension and spasms by passively moving muscle fibers and relaxing stretched muscles, thus eliminating fatigue. Expanded capillaries and opened reserve vessels improve blood circulation, ensuring timely oxygen and nutrient supply to muscles, enhancing nerve, muscle, and organ vitality, and promoting the absorption and elimination of metabolic byproducts like lactic acid—ultimately improving efficiency and reducing fatigue. Hand massage is generally performed during or after training, lasting no more than 10–20 minutes. Treatment focuses on activating blood circulation and removing stasis, as well as soothing tendons and unblocking meridians. Due to the limited hand muscle mass, techniques with large ranges like grasping or rolling are unsuitable. Instead, friction-based and joint-mobilization techniques such as kneading, wiping, pinching, lifting, stroking, and stretching are preferred. Sun Hepu’s research on localized muscle fatigue in rats showed that pinching significantly delayed fatigue, extended working time, and accelerated recovery.
4. Topical Herbal Medicine External herbal treatments include soaking hands in herbal solutions or directly applying herbal pastes. Soaking leverages heat to dilate blood vessels, reduce peripheral resistance, increase blood flow, and enhance lymphatic circulation. Opened pores absorb active herbal compounds more efficiently, while sweat and sebaceous glands improve excretion, rapidly removing harmful substances (like urea nitrogen) and fatigue-inducing agents (like lactic acid). Soaking is typically done before bedtime, lasting 20–30 minutes at around 50°C for optimal results. Zhao Xin et al. compared traditional herbal soaking for hand swelling and found the treatment group showed better improvement in swelling reduction, joint mobility, and pain relief compared to the placebo group. Direct herbal application allows active compounds to penetrate the skin and reach deep fatigue- and pain-affected areas, effectively relieving muscle fiber spasms, improving microcirculation, and reducing stiffness and soreness. Herbal powders (about 0.5 cm thick) are applied to paper, heated, and placed on affected areas. Common herbs include ephedra, cinnamon twig, saposhnikovia, notopterygium, and angelica dahurica (for dispelling cold), as well as safflower, ligusticum, motherwort, notoginseng, and turmeric (for activating blood circulation). Additional tonifying herbs like astragalus, codonopsis, angelica, and rehmannia may be included based on symptoms. Herbal selection varies with fatigue severity and the athlete’s age.
5. Physical Therapy Physical therapy uses instruments to apply various physical stimuli (e.g., electromagnetic waves, ultrashort waves, infrared, and low-frequency current) to trigger bodily responses that regulate, promote, maintain, or restore physiological functions, counteract causes, and achieve therapeutic goals. These physical energies (heat, electricity, magnetism, light, sound) applied locally can relieve pain, reduce swelling, improve circulation, and regulate neuromuscular tension—aiding hand fatigue recovery. Studies on treating muscle adhesions found low-frequency current therapy highly effective: its micro-vibrations inhibit or interrupt pain signal transmission, providing analgesia. Pulsed-modulated currents boost peripheral circulation, eliminate edema, absorb inflammation, relieve spasms, and reduce pain. Low-frequency current also delivers warmth, dilating local blood vessels, enhancing cell permeability, aiding inflammation absorption, boosting metabolism, and reducing inflammation and pain.
Summary
Rock climbing demands high hand strength, making the hands the most susceptible to exercise fatigue. Recovery is crucial for athletes. Combining methods like massage, topical herbs, physical therapy, acupuncture, and nutrition—or using multiple approaches together—can effectively address hand fatigue, helping climbers regain performance and improve results. However, research on hand fatigue recovery in rock climbing remains limited and warrants further study.
