This paper applies machine learning and 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, then describe a variation generator that is designed to...

Dynamic high-resolution ultrasonography findings obtained in 34 extreme rock climbers with finger injuries were compared with those in 20 healthy volunteers. Thicknesses of the flexor tendon and A-2 flexor tendon pulley system were measured at the base of the proximal phalanx. The distance between the tendon and phalanx was evaluated with the finger in extension and in forced flexion as a measu...

Abstract Study aim : The increase in the number of professional climbers led to development since early age. Therefore, average age elite has decreased over last decade. Consequently, and maturity specifics should be investigated with influential factors climbing. This research aimed investigate forearm muscle strength youth sport determine gender, age, status as influence on performance climbe...

Vol. 6, No. 3, pp. 480-489, 2011. The different demands of competition coupled with the morphological and physiological characteristics of cyclists have led to the appearance of cycling specialities. The aims of this study were...

Finger flexor pulley system injuries are the most common overuse injury in rock climbers. These occur rarely outside of climbing, owing to sport’s unique biomechanical demands on finger. As climbing continues grow and earn recognition as a mainstream sport, an understanding how diagnose treat these also has become important. Our purpose is describe current concepts anatomy, biomechanics, clinic...

This study investigates the hypothesis that shallow edge lifting force in high-level rock climbers is more strongly related to fingertip soft tissue anatomy than to absolute strength or strength to body mass ratio. Fifteen experienced climbers performed repeated maximal single hand lifting exercises on rectangular sandstone edges of depth 2.8, 4.3, 5.8, 7.3, and 12.5 mm while standing on a forc...

INTRODUCTION Rock climbing is becoming both accessible and popular amongst a broader population base [1]. This increasing participation has been matched by an increasing injury rate, particularly injuries to the distal upper extremity [2]. The most common climbing injuries occur in the finger flexor tendon pulleys, which can be overloaded to failure by acute excessive force in compromised finge...
