Sport Climbing


Sport climbing is a style of rock climbing that relies on permanent anchors fixed to the rock, especially bolts, for protection, in contrast with traditional climbing, in which the rock is typically devoid of fixed anchors, and climbers must place removable protection as they climb. Since the need to place protection is virtually eliminated, sport climbing places an emphasis on gymnastic ability, strength and endurance, as opposed to adventure, risk and self-sufficiency. Since artificial means are used primarily for safety rather than to make upward progress, sport climbing is considered a form of free climbing.

On a route suitable for sport climbing, pre-placed bolts follow a line up a rock face. Sport climbs are typically between 12 and 36 m in length, and have eight to twelve bolts (some routes may have as few as three bolts, while other routes may have twenty-five or more).



Sport climbing can be undertaken with relatively little equipment. Equipment used in sport climbing includes:

* A dynamic rope
* Quickdraws
* A belay device
* Climbing harnesses for belayer and climber
* Climbing Shoes and chalk bag are normally used, although not technically necessary

Two quickdraws. The left side of the draws are clipped directly to the bolt. The rope will be clipped through the right side.

To lead a sport climb is to ascend a route with a rope tied to the climber's harness, and with the loose end of the rope handled by a belayer. As each bolt is reached along the route, the climber attaches a quickdraw to the bolt, and then clips the rope through the hanging end of the quickdraw. This bolt is now protecting the climber in the event of a fall. At the top of sport routes, there is typically a two-bolt anchor that can be used to return the climber to the ground or previous rappel point.

Because sport routes do not require placing protection, the climber can concentrate on the difficulty of the moves rather than placing protection or the consequences of a fall.

Sport climbing differs from traditional climbing with respect to the type and placement of protection. Traditional climbing uses mostly removable protection (such as cams or nuts), and tends to minimize the usage of pre-placed protection. Sport climbing typically involves single pitch routes, whereas traditional climbing can include single-pitch routes as well as longer, multi-pitch ascents. There are areas like El Potrero Chico that feature multi-pitch sport climbs, but longer routes generally lack pre-placed anchors due to economical, logistical or ethical reasons.

Rock types that produce good sport climbs include limestone, granite and quartzite, though sport climbs can be found on almost all rock types.

Sports Science | Leaders in Sports Nutrition | Sports Training



Sport science is a discipline that studies the application of scientific principles and techniques with the aim of improving sporting performance. Human movement is a related scientific discipline that studies human movement in all contexts including that of sport.

The study of sports science traditionally incorporates areas of physiology, psychology, motor control and biomechanics but also includes other topics such as nutrition and diet, sports technology, anthropometry kinanthropometry and performance analysis.

Sports scientists and performance consultants are growing in demand and employment numbers, with the ever-increasing focus within the sporting world on achieving the best results possible. Through the study of science and sport, researchers have developed a greater understanding on how the human body reacts to exercise, training, different environments and many other stimuli.

The origins of exercise physiology are traced back to the early Greek physicians. Such as the noted ancient Greek physician Galen (131–201) who wrote 87 detailed essays about improving health (proper nutrition), aerobic fitness, and strengthening muscles. Assyrian Hunayn ibn Ishaq translated Galen's work, along with that of Hippocrates, into Arabic which lead to the spread of Greek physiology throughout the Middle East and Europe. Between 776 BC to 393 AD, the ancient Greek physicians planned the training regimens and diets of the Olympic competitors, which developed many principles still used today.

New ideas upon the working and functioning of the human body emerged during the renaissance as anatomists and physicians challenged the previously known theories. These spread with the implementation of the printed word, the result of Gutenberg's printing press in the 15th century. Allied with this was a large increase in academia in general, universities were forming all around the world. Importantly these new scholars went beyond the simplistic notions of the early Greek physicians, and shed light upon the complexities of the circulatory, and digestive systems. Furthermore by the middle of the 19th century early medical schools (such as the Harvard Medical School, formed 1782) began appearing in the United States, whose graduates went on to assume positions of importance in academia and allied medical research.

Medical journal publications in the United States increased tremendously during this period. In conjunction the developments in America were also continuing across Europe. In 1898, three articles on physical activity appeared in the first volume of the American Journal of Physiology. Other articles and reviews subsequently appeared in prestigious journals. The German applied physiology publication, Internationale Zeitschrift fur Phsyiologie einschliesslich Arbeitphysiologie (1929–1940; now know as the European Journal of Applied Physiology and Occupational Physiology), became a significant journal in the field of research.

From this period to the modern day, a number of key figures have moulded the field into what it is today. Below is a selection of just a few of these:

Higher-education degrees in sports science or human physiology are also becoming increasingly popular with many universities now offering both undergraduate and postgraduate degrees in the discipline. Opportunities for graduates in these fields include employment as a physical education teacher, dietician or nutritionist, performance analyst, sports coach, sports therapist, fitness center manager, sports administrator, strength and conditioning specialist or retail manager of a sports store. Graduates may also be well positioned to undertake further training to become an accredited physiotherapist, exercise physiologist or clinical exercise consultant.

There are many noted institutions in the United Kingdom which run courses in sport and exercise sciences. Some of the more well known are Liverpool John Moores, Leeds, Loughborough, Exeter, Bath, Birmingham, Bangor and Heriot-Watt.

Within the United States, The University of Southern Mississippi offers degrees in Sports and High Performance Materials.
