Performance indicators in speed climbing: insights from the literature supplemented by a video analysis and expert interviews

Frontiers in Sports and Active Living, 2023
Due to the goal of mastering a standardised route with relatively large handholds as quickly as possible, the weighting of performance-determining factors might be different in speed climbing in comparison to lead climbing or bouldering. The objective of

Stair climbing and incident atrial fibrillation: a prospective cohort study

Environmental Health and Preventive Medicine, 2022
Background: A protective role for physical activity against the development of atrial fibrillation (AF) has been suggested. Stair climbing is a readily available form of physical activity that many people practice. Herein, we investigated the association

Anthropometric Parameters and Body Composition in Elite Lead Climbers and Boulderers—A Retrospective Study

Applied Sciences
Based on previous research studies and systematic reviews, success in sport climbing seems to be determined by variables such as strength, power, or endurance.

Surface Mechanical Effects of Wildfires on Rocks in Climbing Areas

Fire, 2023
Wildfires are widely recognized as a cause of mechanical damage to rocks. Nevertheless, previous research has neglected how wildfires might impact sport climbing areas. In Spain, two large wildfires affected two climbing areas between 2020 and 2021. This

Psychological factors that influence performance in youth advanced climbers

Social Sciences and Humanities Open, 2023
Introduction: Rock climbing performance in lead can be measured in two ways: on-sight and red-point. On-sight climbing demands greater physiological and psychological factors. There are five main recurring themes that keep climbers highly motivated: risk

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Heart Rate Behavior in Speed Climbing

Frontiers in Psychology, 2020
Speed climbing is an Olympic discipline within the combined sport climbing event in 2020 for the first time. Speed climbing is a high-speed and anaerobic exercise against gravity over a few seconds with extreme psychological pressure.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Automated Video Assistant Referee in Lead Climbing

Current Issues in Sport Science
Introduction In lead climbing, points are awarded for each hold held, which are then primarily decisive for the ranking. These points are awarded immediately after an attempt by a judge who observed the athlete.
