The role of the Cerebellum in rock climbing

Author: Lin CY, Kuo SH | Year: 2017
Summary/Results: A letter to the editor rather than a paper, the authors challenge the connection between coordinated motor performance of the body and the cerebellum (a part of the brain which facilitates muscle contraction timing and precision) in the brain by reporting on a single case study involving an individual with a damaged cerebellum who is relatively good at rock climbing, having won the gold medal for his category at the Climbing Adaptive National Championships in the United States, but poor on traditional measures associated with normal human movement,.  The authors provide alternative theories for this disconnect, including compensation by another part of the brain, as well as distinctions between horizontal (walking) and vertical (climbing) movement.  In their study of video of the individual crawling and climbing, the authors suggest that the stability produced by the movement of four limbs over two requires less “cerebellar-dependent coordination”.

Rock climbing and acute emotion regulation in patients with major depressive disorder in the context of a psychological inpatient treatment: a controlled pilot trial

Author: M. Kleinstauber, M. Reuter, N. Doll, AJ Fallgatter | Year: 2017
Summary/Results: Researchers tested the effect of two exercises, a rock climbing exercise and a relaxation exercise, on 40 individuals with depression.  The study found that the rock climbing group had better outcomes in terms of their depression, their positive and negative emotional states, and emotional coping ability after the exercise. One qualification of the study is that participants could choose which group they participated in.

The effect of potential fall distance on hormonal response in rock climbing

AUTHOR: J. Balas, D. Giles, L. Chrastinova, K. Karnikova, J Kodejska, A. Hlavackova, L. Vomacko, N. Draper | Year: 2017
SUMMARY/RESULTS: Researchers measured the concentration of a variety of hormones before and after climbing in two different groups of climbers: in one group, the climbers clipped all of the bolts available on a route, and in the other groups, the climbers skipped every other bolt. The group that clipped half of the bolts saw a bigger increase in concentration of all hormones measured compared to the group that clipped every bolt.

Motivational orientation and risk taking in elite winter climbers: A qualitative study

AUTHOR: G. Jones, J. Milligan, D. Llewellyn, A. Gledhill, MI Johnson | Year: 2017
SUMMARY/RESULTS: Jones et al. examined the experiences of elite winter climbers to understand their motivation for risk-taking behavior. This qualitative study suggests that climbers pursue risk taking behavior as a result of a choice partially associated with the success of others, and partially associated with their own personal desire to master themselves as well as the identified goal.

The effects of eight weeks sport rock climbing training on anxiety

AUTHOR: A. Ewert, D. Aras | Year: 2016
SUMMARY/RESULTS: Nineteen students were examined for the effects of 8 weeks of sport rock climbing training on anxiety by breaking them up into two groups: a group that climbed and a group that did not. The program suggests that sport rock climbing training significantly reduces cognitive and somatic anxiety, increases self-confidence, and increases the oxygen volume of participants.

Coordination in climbing: effect of skill, practice and constraints manipulation

AUTHOR: D. Orth, K. Davids, L. Seifert | Year: 2016
SUMMARY/RESULTS: Orth et al. conducted a review of 42 studies on perception and movement in climbing. The authors conclude that both perception and movement are highly significant for increasing a climber’s ability, specifically that climbing is supported by: superior perception of climbing opportunities; fitting their body to the shape, distances, and moves of the wall; limb coordination; the direction of the climb and contact with the holds; and minimization of exploratory behavior. Beta-Angel note: while minimization of exploratory behavior appears to be important for performance, other research (see motor learning section) suggests exploratory behavior may be important for learning and transfer of lessons across multiple situations.

Climbing with a head-mounted display

AUTHOR: A. Woodham, M. Billinghurt, WS Helton | Year: 2016
SUMMARY/RESULTS: Researchers measured whether climbing performance and word recall were impacted under conditions where a head-mounted display showed climbers words and an auditory signal sounded during both (a) climbing tests, and (b) sitting tests. Woodham et al. suggest that physical tasks may be more detrimental to word recall than seated tasks and that visual stimuli might hinder climbing performance more than do audible stimuli.

Heart Rate, Perceived Effort, and Anxiety during Top Rope & Lead Rock Climbing

AUTHOR: S. N. Drum, M. Kilgas, K. Phillips, P. B. Watts | Year: 2016
SUMMARY/RESULTS: Researchers tested 10 intermediate level climbers on both top rope and lead routes, specifically looking at heart rate and perceived effort. The authors found that lead climbing produces greater minimum and average heart rates, but not with respect to maximum heart rate or level of perceived effort despite significantly greater time to complete the route.

Risk taking and ethics in rock climbing

AUTHOR: G. B. Gonzalez1 , C. M. Conroy1 | Year: 2016
SUMMARY/RESULTS: Researchers studied data from a series of 1:1 interviews and an online questionnaire filled out by 101 rock climbers which studied sensation seeking and risk-taking to determine how these factors related to demographics. The researchers suggest that climbers carefully consider risks within the sport and do not engage in risky behavior outside of climbing.

Anxiety level and ability to climb routes in recreational indoor climbing

AUTHOR: P. Czermak | Year: 2016
SUMMARY/RESULTS: Researchers compared anxiety with technique across both top rope and lead climbing in a group of intermediate level climbers. The researchers found that a higher level of anxiety influenced climbing ability and technique, and that technique was also reduced specifically during lead climbing. Beta-Angel note: we hear at the project prefer the term “gaggle” of climbers to “group”, or perhaps a “murder” of climbers… occasionally a “school” of them (but only when they’re learning… together… as a group).

Motivation and Habit Formation: An Exploration of Rock Climbing and Its Implications for Exercise Participation

AUTHOR: E. Dagnan, OTD, C-EP, B. Wood, J. Lazzaro, C. Morabbi, T. Zerwic, A. Bernard, & A. Byland | Year: 2016
SUMMARY/RESULTS: The study’s authors studied 77 individuals to understand bot hthe motivation and barriers to climbing. The authors found that exercise balance, personal growth and challenges were the most commonly reported motivators that injury and time were the most common barriers, and that participants began climbing with external motivators but relied on internal motivators to continue climbing. Beta-Angel note: I always thought the more experienced climbers were motivated by external factors like social gatherings and beer.

The effect of anxiety about falling on selected physiological parameters with different rope protocols in sport rock climbing.

AUTHOR: D. Aras, C. Akalan | Year: 2014
SUMMARY/RESULTS: Researchers had a group of climbers top-rope a climb, and another group of climbers lead the same climb. They measured several physiological factors related to energy and oxygen consumption before and after each climber climbed, and also had them take a survey about their anxiety levels. They found that lead climbers tended to report higher levels of anxiety, as well as more energy consumption than top-rope climbers.

Pattern Recognition in cyclic and discrete skills performance from inertial measurement units

AUTHOR: L. Seifert, M L’Hermette, J. Komar, D. Orth, F. Mell, P. Merriaux, P. Grenet, Y. Caritu, R. Herault, V. Dovgalecs, K. Davids | Year: 2014
SUMMARY/RESULTS: Researchers attempted to ensure that a technical system called an “inertial measurement unit” works to help understand pattern recognition, joint angle and limb orientation in rock climbers of different levels. The technical systems were a success, able to assess the variations in movement and coordination between individuals and within individuals in order to understand the adaptation of climbers to different climbs.

Manipulating cardiovascular indices of challenge and threat using resource appraisals.

AUTHOR: MJ Turner, MV Jones, D Sheffield, JB Barker, P Coffee | Year: 2014
SUMMARY/RESULTS: Researchers used two studies (one specific to rock climbing, the other throwing) and provided different instructions to participants within each task which led to cardiovascular activity: one focused on emphasizing the “threat” of the task, and the other the “challenge” of the task. Instructions differed in terms of perception of the difficulty (threat) or as a challenge to overcome (challenge), and also the extent to which previous participants either struggled (threat) or persevered (challenge). Previously, challenge instructions have been found to be related to superior performance in a range of tasks – however, Turner et al. found that there appeared to be no difference in rock climbing performance based upon the instructions given to participants.

Dual-task interference between climbing and a simulated communication task.

AUTHOR: KA Darling, WS Helton | Year: 2014
SUMMARY/RESULTS: Researchers set out to build on previous research which suggests that impairment of memory occurs during climbing. Researchers looked at the ability of climbers to associate words and the ability to recall words, and found that word recall was reduced when required to associate words, but not when they didn’t. Darling and Helton suggest that the task of climbing may interfere with rehearsal and maintenance of words in memory.

A Preliminary Analysis of Motivation and Goal Orientation in Rock Climbers

AUTHOR: G. B. Gonzalez, P. Gonzalez | Year: 2014
SUMMARY/RESULTS: Researchers measured 92 climbers for demographic questions, a questionnaire, and on a scale of motivation. Climbers scored highest in terms of intrinsic (or voluntary based on interest) motivation and task (focused on tasks at hand rather than goals) orientation and the researchers suggest that age and other climbing-related factors may play a role in individual motivation to engage in climbing.

A psychophysiological comparison of on-sight lead and top rope ascents in advanced rock climbers

AUTHOR: S Fryer, T. Dickson, N. Draper, G. Blackwell, S. Hillier | Year: 2013
SUMMARY/RESULTS: Researchers tested the idea that lead climbing may be physiologically and psychologically more stressful than top rope climbing for advanced climbers by comparing stress in 31 climbers as measured pre-climb by an anxiety assessment and measured at interval by plasma cortisol (a hormone released as a response to stress), oxygen volume, and heart rate. Fryer et al state that while heart rate was significantly elevated during the last part of the route, climbers do not find lead climbing more stressful than top rope climbing during on-sight.

Prolonged rock climbing activity induces structural changes in cerebellum and parietal lobe.

AUTHOR: M. Di Paola, C. Caltagirone, L. Petrosini | Year: 2013
SUMMARY/RESULTS: Researchers analyzed the rains of 10 world-class mountain climbers and 10 individuals with no climbing experience to determine whether climbing changes parts o fthe brain. The authors of the study found differences in a section of the brain known as the “vermian lobules I-V” which they suggest is related to highly dexterous hand movements and to movement coordination and visual perception. They also found enlargement of the “parietal” area (normally associated with sensation) is related to predicting the consequences of action in order to correct for it.

Effect of style of ascent on the psychophysiological demands of rock climbing in elite level climbers

AUTHOR: Tabitha Dickson, Simon Fryer, Gavin Blackwell, Nick Draper & Lee Stoner | Year: 2012
SUMMARY/RESULTS: Dickson et al. wanted to measure the difference between a top rope on-sight climb and a lead on-sight climb by measuring the perception of anxiety pre-climbing, blood lactate (a byproduct of the body’s use of simple sugars formed in association with muscular fatigue, often associated with being “pumped”), and plasma cortisol concentration (a hormone released in response to stress) while climb time, heart rate, oxygen consumption, blood lactate, plasma cortisol concentration and task load were measured in response to the climb. The researcher’s results indicate that the physiological and psychological responses of elite level climbers do not differ for lead and top rope on-sight ascents. Beta-Angel note: I don’t know, I think top roping is so next level.

SUMMARY/RESULTS: Researchers studied plasma cortisol (a hormone released in response to stress) concentrations, anxiety, and self-confidence in 19 intermediate climbers during an on-sight climb. Researchers found that the style of ascent (lead or top rope) did not matter with respect to any of the measured variables, and that there was a strong relationship between plasma cortisol concentrations and both self-confidence (lower cortisol to higher self-confidence) and anxiety (lower cortisol to lower anxiety).

Training with mild anxiety may prevent choking under higher levels of anxiety

AUTHOR: R.R.D. Oudejans, J.R. Pijpers | Year: 2010
SUMMARY/RESULTS: The researchers had two groups of novice climbers practice throwing darts while hanging low on a wall. In one group, the researchers induced mild anxiety, while the other practiced without anxiety. Later, both groups’ performances were tested under low, mild, and high anxiety conditions. The climbers who practiced under anxiety did equally well under all three conditions, while the climbers who practiced under no anxiety did worse as anxiety levels went up. These results suggest that climbing under low levels of stress can increase ability to perform during high levels of stress.

Anxiety-performance relationships in climbing: a process-oriented approach

AUTHOR: JR Pijpers, RRD Oudejans, F. Holsheimer, FC Bakker | Year: 2003
SUMMARY/RESULTS: Authors of the study measured anxiety, heart rate, blood lactate (a byproduct of the body’s use of simple sugars formed in association with muscular fatigue, often associated with being “pumped”) concentration, and muscle fatigue, and climbing time and ease of movement in 13 novice climbers in order to understand anxiety and behavior in low- and high-anxiety climbing situations. The results showed that climbing higher produced more anxiety, that heart rate, muscle fatigue, and blood lactate concentrations were all significantly elevated, and that the ease, or fluency, of movement (as measured by the length of climbing time and geometric entropy) was impacted negatively.
