Beta (climbing)
Beta is climbing jargon that designates information about how to ascend a climb (such as, "grab flake on left while moving right foot to edge on right"). Description The complexity of beta can range from a small hint about a difficult section (referred to as "some" beta), to a step-by-step instruction of the entire climb (referred to as "the" beta). In rock climbing this may include information about a climb's difficulty, crux, style, length, quality of rock, ease to protect, required equipment, and specific information about hand or foot holds. For mountaineering, beta may include information about the length and difficulty of the approach, availability of water on the climb and the approach, ease of exiting the route before completing it, descent information, perhaps even useful logistic information for climbs in foreign countries. Sometimes beta is also drawn, in the form of a ''beta-map''. It is not uncommon for climbers to have different betas for the same climb. In ot ...

Boulder Worldcup 2017 Munich Finals 9529
In geology, a boulder (or rarely bowlder) is a rock fragment with size greater than in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks or stones. The word ''boulder'' derives from ''boulder stone'', from the Middle English ''bulderston'' or Swedish ''bullersten''.

Rock Climbing
Rock climbing is a sport in which participants climb up, across, or down natural rock formations. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. 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. Knowledge of proper climbing techniques and the use of specialized 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, such as scrambling, bouldering, sport climbing, and trad (traditional) climbing another activity involving the scaling of hills and similar formations, differentiated by the rock climber's sustained use of hands to support their body weight as well as to provide balance. Rock climbing competitions have the objectives of either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade (climbing)
In rock climbing, mountaineering, and other climbing disciplines, climbers give a grade to a climbing route or boulder problem, intended to describe concisely the difficulty and danger of climbing it. Different types of climbing (such as sport climbing, bouldering or ice climbing) each have their own grading systems, and many nationalities developed their own, distinctive grading systems. There are a number of factors that contribute to the difficulty of a climb, including the technical difficulty of the moves, the strength, stamina and level of commitment required, and the difficulty of protecting the climber. Different grading systems consider these factors in different ways, so no two grading systems have an exact one-to-one correspondence. Climbing grades are inherently subjective.Reynolds Sagar, Heather, 2007, ''Climbing your best: training to maximize your performance'', Stackpole Books, UK, 9.

Crux (climbing)
A crux in climbing, mountaineering and high mountain touring is the most difficult section of a route, or the place where the greatest danger exists. In sport climbing and bouldering, the most technically challenging point in the climb is also called the ''crux'' section. In describing a climbing route using a topo (climbing), topo, cruces (or cruxes) are usually shown with a key symbol. The climbing grade, grade of a climbing route is based on the technical difficulty of the crux (e.g. in the sport climbing system, or in the bouldering system), and for traditional climbing routes, an additional grade is used for the risk of personal injury to a climber of a fall at the crux (e.g. the Grade (climbing)#British, British E-grade system). That means the rest of the route might be considerably easier, however, a route may comprise several cruces of equal difficulty, or simply be a route of a very consistent level of difficulty with no sections that stand out as harder than the rest. ...

Climbing Protection
Climbing protection is any of a variety of devices employed to reduce risk and protect others while climbing rock and ice. It includes such items as nylon webbing and metal nuts, cams, bolts, and pitons. Different forms of climbing draw on varying forms of protection and the systems that are created from its elements. Types of climbing There are a number of ways to "protect" a climb, varying according to the type of climbing: Lead climbing A lead climber places protection (temporary or permanent anchors) in the rock, snow, or ice establishing a climbing route. The rope is clipped through carabiners (often joined by a short length of webbing into a pair known as a quickdraw) which are in turn connected to the protection. The belayer pays out rope during the ascent, and manually arrests the climber's fall by locking the rope, typically with some form of belay device. Aid climbing Aid climbing involves standing on or pulling oneself up via devices attached to fixed or pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing Equipment
A wide range of equipment is used during rock or any other type of climbing that includes equipment commonly used to protect a climber against the consequences of a fall. Rope, cord and webbing Climbing ropes are typically of kernmantle construction, consisting of a core (kern) of long twisted fibres and an outer sheath (mantle) of woven coloured fibres. The core provides about 70% of the tensile strength, while the sheath is a durable layer that protects the core and gives the rope desirable handling characteristics. Ropes used for climbing can be divided into two classes: dynamic ropes and low elongation ropes (sometimes called "static" ropes). Dynamic ropes are designed to absorb the energy of a falling climber, and are usually used as belaying ropes. When a climber falls, the rope stretches, reducing the maximum force experienced by the climber, their belayer, and equipment. Low elongation ropes stretch much less, and are usually used in anchoring systems. They are al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climbing Hold
A climbing hold is a shaped grip that is usually attached to a climbing wall so climbers can grab or step on it. On most walls, climbing holds are arranged in paths, called routes, by specially trained route setters. Climbing holds come in a large array of sizes and shapes to provide different levels of challenge to a climber. Climbing holds are either bolted to a wall via hex-head bolts and existing t-nuts or they are screwed on with several small screws. In extreme cases, concrete anchors may be used (if putting holds on the underside of a bridge, for example). Early materials Rock Early climbing holds were made from real rocks that were cast into concrete blocks; later they were rocks with holes drilled in them so they could be attached to a wall. While the feel of these holds is realistic, rock holds are heavy and can polish with heavy use. Rock holds are also difficult to manufacture. Wood Wood was another early hold-making material, mainly because it was inexpensi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountaineering
Mountaineering or alpinism, is a set of outdoor activities that involves ascending tall mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing. The consequences of mountaineering on the natural environment can be seen in terms of individual components of the environment (land relief, soil, vegetation, fauna, and landscape) and location/z ...

Betamax
Betamax (also known as Beta, as in its logo) is a consumer-level analog recording and cassette format of magnetic tape for video, commonly known as a video cassette recorder. It was developed by Sony and was released in Japan on May 10, 1975, followed by the US in November of the same year. Betamax is widely considered to be obsolete, having lost the videotape format war which saw its closest rival, VHS, dominate most markets. Despite this, Betamax recorders continued to be manufactured and sold until August 2002, when Sony announced that they were discontinuing production of all remaining Betamax models. Sony continued to sell Betamax cassettes until March 2016. Original version Launch and early models The first Betamax device introduced in the United States was the LV-1901 console, which included a color monitor, and appeared in stores in early November 1975. The cassettes contain videotape in a design similar to that of the earlier, professional , U-matic format. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
