Bachar Ladder
The Bachar ladder is a form of rope or metal ladder used as a training device by rock climbers to improve upper body strength. Named after noted free soloist John Bachar, Bachar ladders typically consist of PVC rungs joined by webbing or cord to create an unstable structure similar to the ratlines of a sailing ship. However, unlike ascending ratlines leaning inward using one's legs for upward progress and arms for steadying, the Bachar Ladder is typically hung at an overhanging angle of 20-45° and climbed from below using only the arms. Whereas the campus board focuses more on powerful, sometimes far-reaching movements, the Bachar ladder differs in that it swings slightly when it is being climbed, requiring the climber to use more core tension to maintain stability. For athletes who have practiced pulling movements using only fixed or stable points, the Bachar ladder can improve the strength and efficiency of climbing/pulling movements. It produces greater engagement of core m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Climbers
Rock climbing is a climbing sports discipline that involves ascending routes consisting of natural rock in an outdoor environment, or on artificial resin climbing walls in a mostly indoor environment. Routes are documented in guidebooks, and on online databases, detailing how to climb the route (called the beta), and who made the first ascent (or FA) and the coveted first free ascent (or FFA). Climbers will try to ascend a route onsight, however, a climber can spend years projecting a route before they make a redpoint ascent. Routes range from a few metres to over a in height, and traverses can reach in length. They include slabs, faces, cracks and overhangs/roofs. Popular rock types are granite (e.g. El Capitan), limestone (e.g. Verdon Gorge), and sandstone (e.g. Saxon Switzerland) but 43 types of climbable rock types have been identified. Artificial indoor climbing walls are popular and competition climbing — which takes place on artificial walls — became an ...

Free Solo
Free solo climbing, or free soloing, is a form of rock climbing where the climber (or ''free soloist'') climbs Solo climbing, solo (or alone) without Climbing rope, ropes or other Rock climbing equipment#Protection devices, protective equipment, using only their climbing shoes and their liquid chalk, climbing chalk. Free soloing is the most dangerous form of climbing, and, unlike bouldering, free soloists climb above safe heights, where a fall can be fatal. Though many climbers have free soloed Grade (climbing), climbing grades they are very comfortable on, only a tiny group free solo regularly, and at grades closer to the limit of their abilities. Some climbers' profiles have been increased by free soloing (e.g. Alex Honnold and John Bachar), but others question the ethics of this, and whether the risks they are undertaking should be encouraged and commercially rewarded. "Free solo" was originally a term of climber slang, but after the popularity of the 2018 Academy Awards, Os ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Bachar
John Bachar (March 23, 1957 – July 5, 2009) was an American rock climber. Noted for his skill at free soloing, he ultimately died during a free solo climb. A fitness fanatic, he was the creator of the climbing training device known as the Bachar ladder. Early life and education Bachar was born in 1957. He grew up in Los Angeles, California, and started climbing at the bouldering hot spot of Stoney Point in the northern San Fernando Valley. After attending Westchester High School, graduating in 1974, he attended UCLA, where his father was a math professor, but dropped out to climb full-time. Obsessed with the sport, he immersed himself in books on physical training and nutrition, and soon was able to outperform his fellow climbers. Fellow students at his high school remember him scaling the exterior high school gym walls on many occasions. Climbing career John Long, John Yablonski, Ron Kauk and Mike Graham, whom Bachar met in the early 1970s, all free soloed with him, star ...

Ratlines
Ratlines () are lengths of thin line tied between the shrouds of a sailing ship to form a ladder. Found on all square-rigged ships, whose crews must go aloft to stow the square sails, they also appear on larger fore-and-aft rigged vessels to aid in repairs aloft or conduct a lookout from above. Rat-boards Rat-boards are lower courses in a ratline, often made of slats of wood (batten A batten is most commonly a strip of solid material, historically wood but can also be of plastic, metal, or fiberglass. Battens are variously used in construction, sailing, and other fields. In the lighting industry, battens refer to linea ...s) for support where the distance between shrouds is greatest. In some instances holes in these slats guide and organise low-tension lines between the deck and the rig. Knotting See also * Footrope References {{Sail Types Sailing rigs and rigging ...

Campus Board
A campus board (or pan Güllich) is a training tool that has been widely adopted by sport climbing, sport climbers to improve their plyometric performance and led to dramatic improvements in climbing technique in all rock climbing disciplines. The campus board was invented in 1988 by German climber Wolfgang Güllich to help him climb the world's hardest consensus-graded route at the time, ''Action Directe (climb), Action Directe'', and has since become a standard training tool for climbers. Other climbing training 'boards' have been developed since the campus board, including the MoonBoard, a small customized overhanging indoor climbing wall also for plyometric performance, and the hangboard (or also the fingerboard), a device for building up static strength, particularly in the fingers, but also in the arms. Description Typically, a user ascends or descends the campus board using only their hands, and often leaping from hold to hold (i.e both hands are off the board while transit ...

Core (anatomy)
The core or trunk is the axial skeleton, axial (central) part of an organism's body (biology), body. In common parlance, the term is broadly considered to be synonymous with the torso, but academically it also includes the head and neck. Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to injury. The major muscles of the core reside in the area of the belly and the mid- and lower back (not the shoulders), and peripherally include the hips, the shoulders and the neck. Muscles Major muscles included are the pelvic floor muscles, transversus abdominis, multifidus, internal oblique, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm (anatomy), diaphragm. The lumbar muscles, quadratus Lumborum (deep portion), deep rotators, as well as cervical muscles, rectus capitus anterior and lateralis, longus coli may also b ...

Motor Unit Recruitment
Motor unit recruitment is the activation of additional motor units to accomplish an increase in contractile strength in a muscle. A motor unit consists of one motor neuron and all of the muscle fibers it stimulates. All muscles consist of a number of motor units and the fibers belonging to a motor unit are dispersed and intermingle amongst fibers of other units. The muscle fibers belonging to one motor unit can be spread throughout part, or most of the entire muscle, depending on the number of fibers and size of the muscle. When a motor neuron is activated, all of the muscle fibers innervated by the motor neuron are stimulated and contract. The activation of one motor neuron will result in a weak but distributed muscle contraction. The activation of more motor neurons will result in more muscle fibers being activated, and therefore a stronger muscle contraction. Motor unit recruitment is a measure of how many motor neurons are activated in a particular muscle, and therefore is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proprioception
Proprioception ( ) is the sense of self-movement, force, and body position. Proprioception is mediated by proprioceptors, a type of sensory receptor, located within muscles, tendons, and joints. Most animals possess multiple subtypes of proprioceptors, which detect distinct kinesthetic parameters, such as joint position, movement, and load. Although all mobile animals possess proprioceptors, the structure of the sensory organs can vary across species. Proprioceptive signals are transmitted to the central nervous system, where they are integrated with information from other Sensory nervous system, sensory systems, such as Visual perception, the visual system and the vestibular system, to create an overall representation of body position, movement, and acceleration. In many animals, sensory feedback from proprioceptors is essential for stabilizing body posture and coordinating body movement.

Elbow
The elbow is the region between the upper arm and the forearm that surrounds the elbow joint. The elbow includes prominent landmarks such as the olecranon, the cubital fossa (also called the chelidon, or the elbow pit), and the lateral and the medial epicondyles of the humerus. The elbow joint is a hinge joint between the arm and the forearm; more specifically between the humerus in the upper arm and the radius and ulna in the forearm which allows the forearm and hand to be moved towards and away from the body. The term ''elbow'' is specifically used for humans and other primates, and in other vertebrates it is not used. In those cases, forelimb plus joint is used. The name for the elbow in Latin is ''cubitus'', and so the word cubital is used in some elbow-related terms, as in ''cubital nodes'' for example. Structure Joint The elbow joint has three different portions surrounded by a common joint capsule. These are joints between the three bones of the elbow, the ...

Shoulder Joint
The shoulder joint (or glenohumeral joint from Greek ''glene'', eyeball, + -''oid'', 'form of', + Latin ''humerus'', shoulder) is structurally classified as a synovial joint, synovial ball-and-socket joint and functionally as a diarthrosis and multiaxial joint. It involves an articulation between the glenoid fossa of the scapula (shoulder blade) and the head of the humerus (upper arm bone). Due to the very loose joint capsule, it gives a limited interface of the humerus and scapula, it is the most mobile joint of the human body. Structure The shoulder joint is a ball-and-socket joint between the scapula and the humerus. The socket of the glenoid fossa of the scapula is itself quite shallow, but it is made deeper by the addition of the glenoid labrum. The glenoid labrum is a ring of cartilage, cartilaginous fibre attached to the circumference of the cavity. This ring is continuous with the tendon of the Biceps, biceps brachii above. Spaces Significant joint spaces are: * The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Range Of Motion
Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another. In biomechanics and strength training, ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. The act of attempting to increase this distance through therapeutic exercises (range of motion therapy— stretching from flexion to extension for physiological gain) is also sometimes called range of motion. In mechanical engineering, it is (also called ''range of travel'' or ''ROT'') used particularly when talking about mechanical devices, such as a sound volume control knob. In biomechanics Measuring range of motion Each specific joint has a normal range of motion that is expressed in degrees. The reference values for the normal ROM in individuals differ slightly depending on age and sex. For example, as an individual ages, they typically lose a small amount of ROM. Analog and trad ...
