Strength Training in Climbing: A Systematic Review

Langer, K, Simon, C, and Wiemeyer, J. Strength training in climbing: A systematic review. J Strength Cond Res 37(3): 751-767, 2023-The aim of this review was to provide an overview of the state of research on strength training in climbing and to answer the question how climbing performance, maximum grip strength, upper-limb strength endurance, maximum upper-limb strength, and upper-limb power as dependent variables are affected by different types of training. Moreover, we addressed the question which training methods and training parameters are most effective in increasing climbing and bouldering performance. Searches of MEDLINE (PubMed), SPORTDiscus, ProQuest, and Google Scholar were conducted for studies that met the following criteria: (a) examining effects of training on at least one of the dependent variables, (b) controlled longitudinal design with pretest and posttest, and (c) detailed information on training parameters and subjects. Twelve studies were included into the review. The quality of the studies was rated according to the PEDro scale, and the training interventions were classified according to training method (maximum strength [MS], hypertrophy [HYP], and endurance [END]), specificity (specific, semispecific, and unspecific), and static or dynamic exercises. For 9 of the 12 studies, effect sizes were calculated and the treatments compared. The results showed (a) positive effects of strength training on all variables, (b) a trend toward a mixture of MS and HYP or END training, (c) a trend toward semispecific exercise, and (d) similar effects for dynamic and static exercise with a trend toward a mixture of both. Coaches and athletes are recommended to combine static and dynamic semispecific exercises in a HYP and MS or END training.
