The effects of high resistance-few repetitions and low resistance-high repetitions resistance training on climbing performance
Author: E. Hermans, V. Andersen, AH Saeterbakken | Year: 2017
Summary/Results: Researchers tested the impact of two experimental protocols: a high-resistance, low-repetition protocol vs. a low-resistance, high-repetition protocol in low- and intermediate-grade climbers over the course of ten weeks. The study also included a group that climbed/trained as “usual”, and all groups had their training controlled for intensity. While both experimental protocols showed improvement in climbing performance in spite of a 50% reduction in climbing, the improvement was not statistically significant. Beta-Angel note: We’re particularly interested in how this related to the control (“usual” climbing) group. However, we don’t have access. Note, the same author who completed “Effect of maximal- and local muscular endurance strength training on climbing performance and climbing-specific strength in recreational climbers: a randomized controlled trial” was also responsible for this study. More information on the protocols and results would be helpful. Please contact us.

Effect of maximal- and local muscular endurance strength training on climbing performance and climbing-specific strength in recreational climbers: a randomized controlled trial
AUTHOR: Espen Hermans | Year: 2016
SUMMARY/RESULTS: Researchers seeking to investigate the effect of strength training on lower skill climbers compared three training regimens (maximal strength training, local muscular endurance, and control) on climbing performance over a 10-week period. Researchers suggest that maximal strength training improved climbing performance for recreational climbers over that of both a control group and a group focusing on endurance. Beta-Angel note: there are some translation issues with the paper that bear further discussion. It’s not clear what the training regimens consisted of. Take a look at “The effects of high resistance-few repetitions and low resistance-high repetitions resistance training on climbing performance” for more details.

A comparison of upper body strength between rock climbing and resistance trained men
AUTHORS: KM Macias, LE Brown, JW Coburn, DD Chen | Year: 2015
SUMMARY/RESULTS: Researchers compared anthropometric variables, such as body fat, and measures of upper body strength, including push-ups and pull ups to failure, grip strength, and pinch strength, of 15 rock climbers and 15 resistance trained men. Resistance training was defined as including squats, deadlifts, bench press, and pull-ups. Rock climbers had greater scores on many of the measures, but not push-ups or absolute grip strength (as opposed to grip strength relative to body weight), suggesting that rock climbing can promote increased upper body strength (relative to body weight) even in the absence of traditional resistance training.

The strength structure of sport climbers
AUTHORS: Stankovic, Ignjatovic, Rakovic, Hodzic | Year: 2014
SUMMARY/RESULTS: Researchers conducted a study on 32 sport climbing competitors competing at the national and international level using 18 measuring instruments in order to evaluate strength specifically. The study identified three “action criteria” (factors) affecting strength which were then tested in both a general, non-specific way as well as a climbing-specific way. These factors are static strength (e.g. non-climbing: wide-grip hangs, climbing: Block (?) under a 90 degree angle), repetitive strength (e.g. non-climbing: regular pull-ups, climbing: pull-ups with two fingers), and explosive strength (e.g. non-climbing: push-ups, climbing: maximal reach with the left hand). Beta-Angel note: for the general tests check out Kurelic et al. (1975) and for the specific-tests check out Stankovic et al. (2009). Unfortunately, the details of each test is in Stankovic’s unpublished doctoral dissertation. Anyone have access to this or at least know what the “Block” test refers to?

Static stretching does not impair sport specific measures of upper-limb force and power in rock climbing
AUTHORS: M.A. Kilgas, K.C Phillips, P.B. Watts | Year: 2014
SUMMARY/RESULTS: Researchers sought out answers to whether past research suggesting an impairment to muscular performance from static stretching in some non-climbing sports also holds for climbing-related activity. Researchers could not find impairments in any of the variables they measured, and suggest that because static stretching increases range of motion, and since range of motion may improve rock climbing performance, static stretching may be beneficial to climbing.

The role of arm position during finger flexor strength measurement in sport climbers
AUTHORS: J. Balas, M. Panackova, J. Kodejska, JD Cochrane, JA Martin | Year: 2014
SUMMARY/RESULTS: Researchers studied the relationship between different arm positions, finger strength, and climbing ability. They found that straight or slightly bent arms, above the head, were the best ways to measure finger strength in climbers if the purpose is to relate it to climbing ability. Beta-Angel note: see the effect of arm and grip position during finger flexor strength measurement in sport climbers for more.

Activity and functions of the human gluteal muscles in walking, running, sprinting, and climbing
AUTHORS: JL Bartlett, B Sumner, RG Ellis, R Kram | Year: 2014
SUMMARY/RESULTS: Researchers measured muscle electrical activity in the gluteus maximus muscles during walking, running, sprinting and climbing. While the authors hypothesized that this electrical activity would be greatest in sprinting and climbing, it turned out to be greatest in sprinting and similar between running and climbing.

Metric characteristics of the specific strength sports climbers tests
AUTHORS: D. Stankovic, A. Joksimovic, A. Rakovic, M. Michailov, D. Pirsl | Year: 2009
SUMMARY/RESULTS: Researchers tested 9 climbing-specific tests on 14 national level climbers of explosive, repetitive, and static strength on 14 climbers based on the amount to which the results vary from one another. While researchers believe that all the tests are acceptable as an estimation of climbing strength, they found that the explosive tests vary the least across the results, that the repetitive strength tests vary very little, and that the results of the static strength tests vary the most. Beta-Angel note: see the “strength structure of sport climbers” for more.

The Human Gluteus Maximus and its Role in Running
AUTHORS: D.E. Liberman, DA Raichlen, H. Pontzer, DM Bramble, E. Cutright-Smith | Year: 2006
SUMMARY/RESULTS: This research looks at the human butt and its role in running. However, it also discusses the distinction between the human butt and the ape butt, specifically with respect to evolutionary design and purpose – potentially the increased leverage of the butt during extension (movement of the leg in a backward direction, such as a backward leg raise), control/stabilization of flexion of the trunk (bending over or curling into a ball), and running. Beta-Angel Note: Even though this article wasn’t specific to rock climbing, it is one of the few Easter eggs I’ve hidden throughout this inventory designed to push us into what one of my colleagues refers to as “adjacent spaces” of research. Of particular enjoyment here are the evolutionary reasons behind the “enlarged GM” or butt.

Muscle volume is a major determinant of joint torque in humans
AUTHORS: Fukunaga T1, Miyatani M, Tachi M, Kouzaki M, Kawakami Y, Kanehisa H. | Year: 2001
SUMMARY/RESULTS: Researchers looked at the relationship of muscle volume, measured by cross-sectional area using MRI, pennation angle, and ultrasonography, and joint torque, defined as ‘maximal force multiplied by the moment arm (a function of distance from the lever’s fulcrum)’ on elbow flexor and extensor muscles. Researchers found that muscle volume of the upper arm is a major determinant of joint torque, regardless of athletic training, as compared to joint torque’s reliance on fiber length.
Beta-Angel note: May have implications for hypertrophic training.

Biomechanical analysis of vertical climbing in the spider monkey and the Japanese macaque
AUTHORS: E. Hirasaki, H. Kumakura, S. Matano | Year: 2000
SUMMARY/RESULTS: Researchers attempted to understand the differences in climbing styles between two types of primates: the spider monkey and the Japanese macaque. Researchers found that the spider monkey uses its forelimbs to keep the body close to the object it is climbing, while the forelimbs of the Japanese macaque likely contribute to propulsion up the wall. Beta-Angel note: Another ‘adjacent space’ article. We’re on a role today with non-human primates. As a general note, this is a rabbit hole that should probably be saved for later once the “primary” articles are identified.

An electromyographic study of arm muscles during climbing
AUTHORS: Koukoubis TD1, Cooper LW, Glisson RR, Seaber AV, Feagin JA Jr. | Year: 1995
SUMMARY/RESULTS: The researchers measured electrical activity in the spreading muscles of the hand (first interosseous), two different forearm muscles (brachioradialis and flexor digitorum superficialis), and an upper arm muscle (biceps brachii) during a hang, pull-up, and lowering movement. The authors suggest that the high activation of the brachioradialis (during pulling and lowering) and flexor digitorum superficialis (throughout hanging, pulling, and lowering), in combination with their elevated incident of injury during climbing, should be targeted for emphasized conditioning.
