A new performance threshold in sport climbing: A change in how climbing trainers work?

Previous research has shown that the finger flexor's occlusion threshold (OT) could be different among sport climbers when expressed as a percentage of their maximum finger force (OT%), and that there is no association between the OT% and the climberś ability level. The aim of the present study was to evaluate the possible association between the relative finger force applied at the OT% (rff-OT%) and climbing ability level. We approximated the finger flexor's OT of 34 sport climbers by finger hang endurance test analyses at different intensities between 35% and 85% of their individual maximum finger force on a previously individually adapted edge depth, and we valued their rff-OT% as the relative force they could perform at that intensity. We found a high correlation between the rff-OT% and climbing ability in elite climbers. These findings suggest that having an OT at the highest possible percentage is critical, in addition to having a high relative finger force, as this would enable climbers to express relative force at a wider range of intensities with favorable metabolic conditions.
