BACKGROUND: The Hajar Mountains of Oman and the United Arab Emirates (UAE) is the highest mountain range in Eastern Arabia. As a result of their old geological origin, geographical isolation, complex topography and local climate, these mountains provide an important refuge for endemic and relict species of plants and animals with strong Indo-Iranian affinities. Among vertebrates, the rock climbing nocturnal geckos of the genus Asaccus represent the genus with the highest number of endemic species in the Hajar Mountains...

We report an unusual case of spinal accessory nerve palsy sustained while transporting climbing gear. Spinal accessory nerve injury is commonly a result of iatrogenic surgical trauma during lymph node excision. This particular nerve is less frequently injured by blunt trauma. The case reported here results from compression of the spinal accessory nerve for a sustained period-that is, carrying a load over the shoulder using a single nylon rope for 2.5 hours. This highlights the importance of using proper load-carrying equipment to distribute weight over a greater surface area to avoid nerve compression in the posterior triangle of the neck...

BACKGROUND: The "weekend warrior" engages in demanding recreational sporting activities on weekends despite minimal physical activity during the week. We sought to identify the incidence and injury patterns of major trauma from recreational sporting activities on weekends versus weekdays. METHODS: We performed a retrospective cohort study using the Alberta Trauma Registry comparing all adults who were severely injured (injury severity score [ISS] ≥ 12) while engaging in physical activity on weekends versus weekdays between 1995 and 2009...

BACKGROUND: The aim of this study was to examine the effect of anxiety about falling on selected physiological parameters on the lead (LC) and top-rope climbing (TRC) methods. For this purpose the physical differences between the two methods have been eliminated and the effect of only the anxiety about falling on the physiological parameters has been studied. METHODS: A total of 26 intermediate level sport rock climbers, 22 male and 4 female with an average age of 27...

OBJECTIVE: Rock climbing's popularity continues to rise, with people of all ages regularly participating in the sport. Climbing literature suggests climbers get injured mostly in their upper extremities. Most studies on climbing injury analysis are conducted retrospectively, with all the inherent problems of a retrospective setup (no exact time collection, biased injury perception, etc). Prospective data are still missing. METHODS: We prospectively evaluated all attendees of a major German indoor climbing gym in Stuttgart, Germany, with bouldering and lead climbing facilities...

OBJECTIVE: There is a lack of data to establish minimal requirements for technical alpine climbing skills needed by rescue teams involved in alpine helicopter rescue operations to perform such operations safely. METHODS: A year of rescue operations (N = 2731) were investigated for the technical difficulties of the terrain. The difficulties were graded according to the Union Internationale des Associations d'Alpinisme (UIAA) scale for rocky terrain and steepness for ice slopes...

BACKGROUND: Previous research has focused on the positive consequences of flow, an intrinsically rewarding state of deep absorption. In contrast, the present research links flow to impaired risk awareness and to risky behaviour. We expected flow to enhance self-efficacy beliefs, which in turn were hypothesised to result in low risk awareness and risky behaviour in sports. In addition, we predicted that individuals' level of experience in the activity would moderate the expected effects...

The main purpose of this study was to examine the effect of chalk on the friction coefficient between climber's fingers and two different rock types (sandstone and limestone). The secondary purpose was to investigate the effects of humidity and temperature on the friction coefficient and on the influence of chalk. Eleven experienced climbers took part in this study and 42 test sessions were performed. Participants hung from holds which were fixed on a specially designed hang board. The inclination of the hang board was progressively increased until the climber's hand slipped from the holds...

AIM: Blood samples for the determination of plasma cortisol concentration are generally obtained via venipuncture or capillary sampling at the fingertip. During rock climbing the upper body, forearms and fingertips are subject to continual loading and gripping making sampling at these sites problematic. The purpose of this study was to examine differences in plasma cortisol concentrations from capillary samples taken at the fingertip and first (big) toe in a rock climbing context. METHODS: Nine (8 males, 1 female) climbers completed a succession of climbing bouts at three different angles (91°,100° and 110°)...

Andreas Schweizer
Rock climbing, sport climbing and bouldering are highly popular new sport disciplines. An increasing number of indoor climbing gyms throughout the country offer the possibility to perform the sport regularly independently from the weather. As a result a variety of new pathologies like the closed flexor tendon pulley rupture of the finger and syndromes caused by overuse mainly in the upper extremity have appeared and should be familiar to physicians and therapists working in the field of sports medicine. An overview of the most common and most specific climbing related injuries as well as their diagnosis and treatment options with a focus on the upper extremity are presented...

This article analyzes whether climbing, a motor activity featured by upward movements by using both feet and hands, generation of new strategies of motor control, maintenance of not stable equilibrium and adoption of long-lasting quadrupedal posture, is able to modify specific brain areas. MRI data of 10 word-class mountain climbers (MC) and 10 age-matched controls, with no climbing experience were acquired. Combining region-of-interest analyses and voxel-based morphometry we investigated cerebellar volumes and correlation between cerebellum and whole cerebral gray matter...

The purpose of this study was to examine 2 recovery modalities (with and without an ice bag treatment) on closed-handed and open-handed weight-assisted pull-ups in recreationally-trained rock climbers. Healthy and recreationally active volunteers (n = 9) completed 4 counterbalanced trials separated by 72 hours. Trials included 3 sets of closed-handed and open-handed weight-assisted pull-ups supported by 50% of body weight, until failure. Between each set, participants sat quietly in a chair and engaged in approximately 20 minutes of either passive or ice bag treatment...

This paper applies the mathematics of chaos to the task of designing indoor rock-climbing routes. Chaotic variation has been used to great advantage on music and dance, but the challenges here are quite different, beginning with the representation. We present a formalized system for transcribing rock climbing problems and then describe a variation generator that is designed to support human route-setters in designing new and interesting climbing problems. This variation generator, termed strange beta, uses chaos to introduce novelty...

Climbing is a sport, a hobby, and metaphor for life's lessons. A climbing course for undergraduate students was designed on the basis of the principles of rock climber and educator Kurt Hahn, who transferred lessons learned from physical activity into lessons for life and whose philosophy underpins the Outward Bound program. Hahn's 10 principles for sound mind-body-spirit are described.

S Fryer, T Dickson, N Draper, G Blackwell, S Hillier
Research suggests that lead climbing is both physiologically and psychologically more stressful than top rope climbing for intermediate performers. This observation may not be true for advanced climbers, who train regularly on lead routes and are accustomed to leader falls. The aim of this study was to compare the psychophysiological stresses of lead and top rope on-sight ascents in advanced rock climbers. Twenty-one climbers (18 men and three women) ascended routes near or at the best of their ability (22 Ewbank)...
