choose to wear specialized rubber climbing shoes which are often of a smaller size than their normal street shoes in order to improve sensitivity towards foot placements and use the tightness to their advantage. Climbing chalk (MgCO3) is commonly used as a drying agent to minimize sweating of the hands. Most other equipment is of a protective nature. Rock climbing is inherently dangerous, so to minimize the potential consequences resulting from a fall, climbers use protection. The most basic protective equipment is a climbing rope. Climbing pioneers would attach the rope to themselves; in the event of a fall, the rope would usually cause injury to the climber in the hope that it prevented death. With advances in technology came the development of specialized harnesses, carabiners which are used for clipping into belay and rappel anchors and connecting gear, and belay devices which are used to catch a falling climber, hold or lower a climber and for rappelling. Eventually, the placement of bolts with the use of quickdraws led to the rise of sport climbing. Traditional climbers developed the spring-loaded camming device, which allowed a wider variety of climbing styles to be adequately protected compared to chocks and hexes. Traditionally pitons were used however in most areas protection which damages the rock is discouraged. Most climbers choose to wear a specialized climbing helmet to protect them from falling rocks or equipment or head injuries from crashing into rocks. Injuries Injuries in rock climbing are mainly sports injuries that occur due to falls or overuse. Injuries due to falls are relatively uncommon; the vast majority of injuries result from overuse, most often occurring in the fingers, elbows, and shoulders. Such injuries are often no worse than torn calluses, cuts, burns and bruises. There are a number of skincare products specifically for climbers available in the market. However, overuse symptoms, if ignored, may lead to permanent damage especially to tendons, tendon sheaths, ligaments, and capsules. Taping of fingers and elbows to prevent injuries is common practice and there are various techniques for taping. Photo topos Illustrated photo-topos are widely used in rock climbing. Many of them are found in climbing and mountaineering guidebooks such as those published by Rockfax, or the British Mountaineering Council. Full-colour photo-topo diagrams have replaced the previous generation of text based guidebooks, which were illustrated with hand-drawn diagrams. The use of drones has helped improve the quality of
