Raúl Aguilar, Carlos Martínez, José R Alvero-Cruz
The cortisol awakening response (CAR) was examined over a 45days stay at extreme altitudes (above of about 5500m) on Mount Kangchenjunga. The CAR refers to a peak cortisol response during the waking period that is superimposed to the diurnal rhythmicity in cortisol secretion, whose function has been proposed to be the anticipation of demands of the upcoming day (the CAR anticipation hypothesis). According to this hypothesis, we distinguished between resting days on which the expedition team engaged in routine activities in the base camp, and ascent days on which it planned to climb up a very demanding track...

Chromosome numbers and heterochromatin banding pattern variability have been shown to be useful for taxonomic and evolutionary studies of different plant taxa. Bignonieae is the largest tribe of Bignoniaceae, composed mostly by woody climber species whose taxonomies are quite complicated. We reviewed and added new data concerning chromosome numbers in Bignonieae and performed the first analyses of heterochromatin banding patterns in that tribe based on the fluorochromes chromomycin A3 (CMA) and 4'-6-diamidino-2-phenylindole (DAPI)...

PURPOSE: To validate heart rate (f H) as an effective indicator of the aerobic demands of climbing, the f H vs oxygen uptake ([Formula: see text]) relationship determined during cycling exercise and climbing on a circular climbing treadwall was compared. Possible differences in maximum aerobic characteristics between advanced and élite climbers were also assessed. METHODS: Seven advanced and six élite climbers performed a discontinuous incremental test on a cycle ergometer and a similar test on a climbing treadwall...

BACKGROUND: The impact of high-intensity, repetitive training on the fingers of adolescent climbers is relatively unknown. OBJECTIVE: To evaluate this effect by ultrasound (US) and to confirm some findings by magnetic resonance imaging (MRI). MATERIALS AND METHODS: The US study was performed in 20 adolescent rock climbers (ages 10-17 years) and 6 non-climbing controls (ages 11-15 years). US was used to examine the third digit of the right hand for differences in thickness of soft tissue, flexor and extensor tendon, volar plate and bony and growth plate adaptations...

This article demonstrates a pneumatically actuated soft robot capable of navigating the inside of a tube. This robot was built using buckling pneumatic actuators (vacuum-actuated muscle-inspired pneumatic structures, or VAMPs). The tube climber can navigate through a tube with turns, inclines, and varying diameters. The robot is also able to remove obstacles (of more than 10 times its own weight) from tubes to perform a clearing function. It maintains climbing and clearing performance in wet conditions and under water...

REVIEW

Climbing plants have unique adaptations to enable them to compete for sunlight, for which they invest minimal resources for vertical growth. Indeed, their stems bear relatively little weight, as they traverse their host substrates skyward. Climbers possess high tensile strength and flexibility, which allows them to utilize natural and manmade structures for support and growth. The climbing strategies of plants have intrigued scientists for centuries, yet our understanding about biochemical adaptations and their molecular undergirding is still in the early stages of research...

Repetitive stress fracture of the middle phalanx epiphysis is an injury specific to elite adolescent sport climbers. As sport climbing becomes increasingly popular in younger age groups, an increased number of these injuries have been reported in recent years. To date, treatment of these fractures has been nonsurgical, with strict rest and physiotherapy prescribed until fracture union. However, when these patients present in a delayed fashion with an established nonunion, nonsurgical treatment may fail, leading to disabling chronic pain and/or digital deformity in some cases...

REVIEW
Dominic Orth, Graham Kerr, Keith Davids, Ludovic Seifert
In this review of research on climbing expertise, we focus on different measures of climbing performance, including spatiotemporal measures related to fluency and activity states (i.e., discrete actions), adopted by climbers for achieving overall performance goals of getting to the end of a route efficiently and safely. Currently, a broad range of variables have been reported, however, many of these fail to capture how climbers adapt to a route whilst climbing. We argue that spatiotemporal measures should be considered concurrently with evaluation of activity states (such as reaching or exploring) in order gain a more comprehensive picture of how climbers successfully adapt to a route...

When the stomata are closed under drought, the only route for water loss from the leaf interior to the atmosphere is across the cuticle. Thus, the extent of cuticular transpiration in relation to the reservoirs of water in the plant and the water acquisition from the soil determines the fitness and survival of the plant. It is, therefore, widely assumed that the cuticular water permeability of plants regularly experiencing drought is comparatively low and, thus, adapted to the environment. To test this hypothesis, 382 measurements of cuticular permeability from 160 species were extracted from the literature published between 1996 and 2017...

Karinen, Heikki M., and Martti T. Tuomisto. Performance, mood, and anxiety during a climb of Mount Everest. High Alt Med Biol. 16:000-000, 2017. BACKGROUND: Various studies have shown the deleterious effects of high-altitude hypoxia on visual, motor, somatosensory, cognitive, and emotional function and also in intelligence tests, reaction time, speech comprehension, hand steadiness, visual contrast discrimination, and word association tests. Because optimal cognitive abilities may be crucial for mountain climbers' safety, this study was intended to evaluate the changes in cognitive performance, mood, and anxiety during an Everest expedition lasting almost 3 months...

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...

Previous investigations have shown that inducing meta-stability in behavior can be achieved by overlapping affordances through constraint manipulation, allowing cooperative and competitive tendencies to functionally coexist. The purpose of this paper was to test a number of conditions applying these design principles on performance during skills practice and transfer. Of additional interest, was whether the existing skill level interacted with the environmental properties of the experimental tasks (varying indoor climbing routes)...
