This bachelor’s thesis examines the ergonomic aspects of sport climbing, focusing on how ergonomics influences performance, injury prevention, and the overall success or failure of a climb. The introduction provides a brief overview of sport climbing, highlighting the role of ergonomics in enhancing physical efficiency and minimizing injury risks. The thesis sets out to explore key objectives, such as understanding how ergonomic principles can optimize a climber’s performance and improve safety. The ergonomic aspects discussed include postural ergonomics, the importance of grip and force distribution, and strategies for managing energy expenditure to avoid fatigue during climbs. The ergonomic design of climbing equipment, such as shoes, harnesses, and holds, is also examined in relation to its impact on performance. In analyzing the principles that contribute to a successful climb, the thesis delves into critical factors such as efficient body mechanics, movement strategies, and maintaining balance by keeping the center of gravity close to the wall. Psychological ergonomics, including mental focus and stress management, is also discussed as a key component of success in climbing. The thesis further explores biomechanical and ergonomic reasons for climbing failure, such as poor technique, improper body positioning, and overexertion. It uses real-world examples and case studies to illustrate how ergonomic inefficiencies can lead to falls or injuries. A significant part of the thesis is dedicated to an ergonomic analysis for injury prevention, detailing common injuries in sport climbing—such as finger injuries and tendonitis—and identifying the ergonomic factors that contribute to them. It offers practical recommendations for preventing injuries through proper technique, warm-ups, and training. Moreover, it explains how climbers can optimize their performance by applying ergonomic principles.
