Abstract

Comfortable joint angles (cja), anthropometrics, range of motion (rom) and sex are crucial for optimising bicycle designs to enhance performance and prevent injuries. previous studies have not comprehensively provided related data, motivating the current study to address three questions: (1) What is the CJA hip and shoulder abduction/adduction (ADD-ABD) for cyclists? (2) How do these measurements vary according to sex and stature? (3) What are the correlations among bicycle variables, anthropometrics, ROM and CJA of the hip and shoulder ADD-ABDs? Data were collected from 12 participants using three bicycles, web cameras and video processing. The analysis showed an average CJA of 26° and 83° for the hip and shoulder ADD-ABDs, respectively. No significant differences were observed between sexes or stature groups. Significant correlations were found between shoulder ADD-ABD and upper-body variables and between hip ADD-ABD and lower-body variables. These findings contribute to improving bicycle designs for individual comfort and performance.

Practitioner summary: The association of comfortable hip and shoulder adduction-abduction angles with anthropometrics, range of motion (ROM), and bicycle variables was investigated using a detailed biomechanical analysis. It offers insights and contributes to a better bicycle design by identifying optimal joint angles for improved ergonomic fit and rider performance.

对自行车设计的人体工程学见解：髋关节和肩部内收外展角度的意义。

舒适的关节角度（cja）、人体测量学、活动范围（rom）和性别是优化自行车设计以提高性能和防止受伤的关键。以往的研究没有提供全面的相关数据，促使本研究解决三个问题：(1)骑车者的CJA髋关节和肩部外展/内收（ADD-ABD）是什么？(2)这些尺寸是如何根据性别和身高变化的？(3)自行车变量、人体测量学、髋关节和肩部ADD-ABDs的ROM和CJA之间有何相关性？研究人员使用三辆自行车、网络摄像头和视频处理技术，从12名参与者那里收集了数据。分析显示，髋关节和肩部ADD-ABDs的平均CJA分别为26°和83°。没有观察到性别或身高组之间的显著差异。肩部ADD-ABD与上半身变量、臀部ADD-ABD与下半身变量之间存在显著相关性。这些发现有助于改善自行车设计的个人舒适性和性能。从业者总结：通过详细的生物力学分析，研究了舒适的髋关节和肩部内收外展角与人体测量学、活动范围（ROM）和自行车变量的关系。它提供了见解，并有助于更好的自行车设计，通过确定最佳的关节角度，以提高人体工程学的配合和骑手的表现。

期刊介绍： Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives. The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
