The relative importance of four muscle groups for indoor rock climbing performance
AUTHORS: MR Deyhle, H. Hsu, TL Cadez-Schmidt, BA Gurney, CM Mermier | Year: 2015
SUMMARY/RESULTS: Researchers attempted to determine the relative importance of four muscle groups (digit flexors, shoulder adductors, elbow flexors, or lumbar flexors) in eleven male rock climbers on a 40 degree overhang by pre-fatiguing one of the individual muscle groups. The results suggested that among the muscle groups studied in men, muscular endurance of the digit flexors and elbow flexors were especially important for the specific terrain.

Connective tissue adaptations in the fingers of performance sport climbers
AUTHORS: T. Schrieber, P. Allenspach, B. Seifert, A. Schweizer | Year: 2015
SUMMARY/RESULTS: Researchers tested whether (at least) 15 years of climbing produces adaptation in climber fingers by measuring the thickness of different tendons in 51 males broken up into a group of climbers and a group of non-climbers. Researchers found that significant adaptation occurred in the flexor tendon pulleys (A2, A4) which wrap around the bone on either side of the second (PIP) joint, as well as the joint capsule (which seals the joint space and holds the joint together) at the closest knuckle (DIP) joint to the tip of the finger.

Estimation of hand and wrist muscle capacities in rock climbers
AUTHORS: L Vigouroux, B Goislard de Monsabert, E Berton | Year: 2015
SUMMARY/RESULTS: Researchers tested five different muscles within the hand and wrist of 9 male and 3 female climbers and compared them to non-climbers. The major difference was identified in the finger flexors of rock climbers, which were 37.1% greater than those of non-climbers. The finger extensor muscles (an antagonist muscle to the finger flexors, which means they have a contract and relax relationship) on the other hand showed no difference with non-climbers, suggesting a discrepancy which may be both potential danger and possible training opportunity.
