Ecomorphology links microhabitat and morphology. By comparing ecomorphological associations across clades, we can investigate the extent to which evolution can produce similar solutions in response to similar challenges. While Anolis lizards represent a well-studied example of repeated convergent evolution, very few studies have investigated the ecomorphology of geckos. Similar to anoles, gekkonid lizards have independently evolved adhesive toe pads and many species are scansorial. We quantified gecko and anole limb length and microhabitat use, finding that geckos tend to have shorter limbs than anoles...

The goal of this study was to assess the impact of a specific four-week training program on finger grip in climbers; specifically, on the maximal force and the rate of force development (RFD) of finger muscles in isometric contraction. The participants were 14 French male rock climbers who took part in national and international bouldering competitions (at world-ranking and elite levels). They were divided into two samples. The experimental group performed a specific four-week training program that included such exercises as suspensions on small holds at the rate of three times a week...

Rock climbing is among the outdoor activities that have undergone the highest growth since the second half of the 20th century. As a result, cliff habitats, historically one of the least disturbed by human colonization worldwide, are facing more intense human pressure than ever before. However, there is little data on the impact of this activity in plant-communities, and such information is indispensable for adequate manager decision-making. The goal of this study was to determine the impact of rock climbing on plant communities in terms of cover, richness, and composition in relation to climbing intensity on typical Mediterranean limestone cliffs...

BACKGROUND: Rock climbing first evolved as a sport in the late 18th century. With its growing popularity, the number of rock climbing-related injuries has potential to increase, spurring a rise in the number of articles associated with it. Despite the available literature, there remains a paucity of information about upper extremity injuries sustained by rock climbers, and no studies to date have focused on gender-specific injuries. METHODS: A 24-question online survey was distributed to rock climbers about upper extremity injuries sustained during rock climbing...

Different ambient temperatures are known to affect muscular performance based on the type of contraction. The effect of cold (10°C) and thermoneutral (TN) (24°C) ambient temperatures on finger flexor performance was examined in 12 rock climbers. After 30 min of seated rest in the designated temperature condition, participants completed maximal voluntary contractions (MVC) on a climbing-specific finger flexor assessment device equipped with a crimp grip hold. Participants then completed an intermittent fatiguing task until failure...

Rock climbing, whether practiced in nature on cliffs and boulders or indoors on walls made of resin and wood, has gained tremendous popularity in recent decades. More people are exposed to injuries associated with the unique biomechanical forces of rock climbing. A series of repetitive high torque movements of the upper limbs are needed to ascend a wall or rockface. These movements subject the hand and wrist to large forces, potentially resulting in ligament and tendon sprains or rupture and even bone fracture...

Rock climbing performance has been suggested to involve a notable contribution from the aerobic metabolism. Previously it has been shown that forearm oxygenation kinetics can be used to distinguish ability groups and predict red-point sport climbing performance. Currently it is not known if forearm oxygenation kinetics, or a sport specific assessment of cardiorespiratory fitness best predicts sport rock climbing performance. The aim of the study was to determine whether forearm oxidative capacity index, maximal de-oxygenation (Δ score) during a treadwall V[Combining Dot Above]O[SUBSCRIPT TWO]peak test, treadwall V[Combining Dot Above]O[SUBSCRIPT TWO]peak, or running V[Combining Dot Above]O[SUBSCRIPT TWO]max best predicts self-reported sport climbing performance...

The present study was designed to determine which types of specific tests provide an effective evaluation of strength and endurance in highly trained competitive sport climbers. The research process consisted of three basic components: the measurement of selected somatic characteristics of the climbers, the assessment of their physical conditioning, and a search for correlations between the anthropometric and "conditioning" variables on the one hand, and climber's performance on the other. The sample of subjects consisted of 14 experienced volunteer climbers capable of handling 7a- 8a+/b on-sight rock climbing grades...

Well, they've defied expectations so far. It was expected that MA enrollment would decline from 10.9 million enrollees (or 24% of all Medicare enrollment) to 8.2 million (15% of Medicare's total enrollment). Instead, enrollment has continued to climb. In 2016, 17.6 million Medicare beneficiaries-or 31% of all beneficiaries-were in MA plans.

OBJECTIVE: Hamate hook fractures are rare injuries, comprising 2% to 4% of all carpal fractures. Climbing athletes seem to be affected more frequently than others, as they strain the passive and active anatomical structures of their hands and fingers to maximum capacity during training or competing. This stress is transmitted to the hook of the hamate by tightened flexor tendons, which creates high contact pressure to the ulnar margin of the carpal tunnel. Injuries of the hamate hook, caused by contact pressure of the anatomical structures, are rare and occur nearly exclusively during climbing...

Lumbrical strain is a relatively unknown hand injury. We report four cases of lumbrical origin strain involving the ring finger flexor tendons. Three patients sustained the injury during rock climbing and one while working with a jackhammer. In all cases, circumferential fluid around the flexor tendons of the ring finger was demonstrated on MRI and/or ultrasound at the distal palmar level at the "bare area," which is normally devoid of a synovial sheath. There is a paucity of information in the literature regarding this injury and its specific imaging features...
