Rock climbing



Rock climbing is an activity in which participants climb up, down or across natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Due to the length and extended endurance required and because accidents are more likely to happen on descent than ascent, Rock Climbers do not usually climb back down the route. It is very rare for a climber to downclimb, especially on the larger multiple pitches (class III- IV and /or multi-day grades IV-VI climbs). Professional Rock climbing competitions have the objectives of either completing the route in the quickest possible time or attaining the farthest point on an increasingly difficult route. Scrambling, another activity involving the scaling of hills and similar formations, is similar to rock climbing. However, rock climbing is generally differentiated by its sustained use of hands to support the climber's weight as well as to provide balance.

Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with mental control. It can be a dangerous activity and knowledge of proper climbing techniques and usage of specialised climbing equipment is crucial for the safe completion of routes. Because of the wide range and variety of rock formations around the world, rock climbing has been separated into several different styles and sub-disciplines.

Climbing techniques

Different types of rock require different techniques to successfully climb.

Crack climbing
Main article: Crack climbing

Crack climbing is a type of rock climbing that ascends cracks and uses specialized climbing techniques. Cracks used in climbing vary in size from the width of a finger to those that fit an entire body. Climbers use techniques such as jamming, laybacking, and stemming. Some climbers use gloves made out of athletic tape to protect their hands.

Face climbing
Main article: Face climbing

Face climbing is a type of climbing where climbers use features and irregularities in the rock such as finger pockets and edges to ascend a vertical rock face.

Slab climbing
Main article: Slab climbing

Slab climbing is a type of rock climbing where the rock face is at an angle of less steep than vertical. It is characterized by balance- and friction-dependent moves on very small holds.

Simul climbing
Main article: Simul climbing

When two climbers move at the same time. The pseudo-lead climber places gear that the pseudo-follower collects. When the leader runs low on gear they construct a belay station where the follower can join them to exchange gear. The stronger climber is often the pseudo-follower since a fall by the follower would pull the leader from below towards the last piece of gear—a potential devastating fall for the leader. In contrast, a fall from the leader would pull the follower from above, resulting in a less serious fall. Most speed ascents involve some form of simul climbing but may also include sections of standard free climbing and the use of placed gear for advancement (i.e. partial aid or pulling on gear).

Via ferrata
Main article: Via ferrata

A method of fairly easily ascending a route, heavily dependent on permanent protection rather than using natural rock features to proceed.

Grading systems
Main articles: Grade (climbing) and Grade (bouldering)

Climbing communities in many countries and regions have developed their own rating systems for routes. Ratings, or grades, record and communicate consensus appraisals of difficulty. Systems of ratings are inherently subjective in nature, and variation of difficulty can be seen between two climbs of the same grade. Hence, there may be occasional disagreements arising from physiological or stylistic differences among climbers. The practice of rating a climb below its actual difficulty is known as sandbagging.

The most commonly used rating systems in the United States are the Yosemite Decimal System and the Hueco V-scale bouldering grade. The current ranges for climbing routes are 5.0 for easy beginner routes to 5.15 being world class and V0 - V16, respectively. As the limit of human climbing ability has not yet been reached, neither grading system has a definite endpoint and is thus subject to revision.
The ratings take into account multiple factors affecting a route, such as the slope of the ascent, the quantity and quality of available handholds, the distance between holds, ease of placing protection and whether advanced technical maneuvers are required. Typically the rating for the hardest move on the wall will be the rating for the whole climb. While height of a route is generally not considered a factor, a long series of sustained hard moves will often merit a higher grade than a single move of the same technical difficulty. For example, a climb with multiple 5.11 moves with no rests may thus be rated a 5.12.

Terminology
Main article: Glossary of climbing terms

As climbing routes or problems increase in difficulty, climbers learn to develop skills that help them complete the climbs clean. There are several techniques for hands and feet as well as terms for motions that combine the two. For indoor gyms, route setters visualize and create routes for climbers, placing different kinds of holds in specific parts of the wall at particular angles because they intend climbers to use certain techniques.

Environments

Indoor climbing
Main article: Indoor climbing

Indoor climbing occurs in buildings on artificial rock structures. This permits for climbing in all types of weather and at all times of day. Climbers climb indoors to improve their skills and techniques, as well as for general exercise or fun. Indoor climbing gyms typically provide rope setups and ensure that new climbers know safe techniques.

Outdoor climbing

Outdoors, climbs usually take place on sunny days when the holds are dry and provide the best grip, but climbers can also attempt to climb at night or in adverse weather conditions if they have the proper training and equipment. However, night climbing or climbing in adverse weather conditions will increase the difficulty and danger on any climbing route.

Equipment
Main article: Rock-climbing equipment

Most climbers 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 increased safety over chocks, hexes, and pitons. Some climbers choose to wear a specialized climbing helmet to protect them from falling rocks or equipment or head injuries from crashing into rocks.

Injuries
Main article: Climbing 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. Injuries from lead climbing are common.

Planning your climb, knowing your partner, talking about your climb, checking your equipment and the conditions of the rocks, checking the weather, using good judgement and always paying attention minimize the risk of injury.
