Abstract

Age is associated with increased tissue stiffness and a higher risk of low back pain, particularly in older, sedentary workers who spend long periods sitting. This study explored how trunk stiffness changes with age and its relationship with posture during prolonged sitting in a sample of 37 women aged 20-65 years. Age was assessed as both Chronological Age and Fitness Age, with trunk stiffness measured using a passive trunk flexion apparatus. Participants sat at a computer workstation for 60 minutes, and spine posture was recorded every 10 minutes. The study found that trunk stiffness significantly increased with age, especially when considering Fitness Age (r = 0.517, p = 0.003). Additionally, trunk stiffness was negatively correlated with spine motion during sitting (r = -0.435, p = 0.023). These findings suggest that workers with poorer health move less while sitting and could be more susceptible to the deleterious effects of sedentary work.

年龄、体能和健康状况对完整下背部被动僵硬的影响及其对健康女性就座工作的影响。

年龄与组织僵硬度增加和腰痛风险增加有关，尤其是那些久坐不动的老年人。这项研究以37名年龄在20-65岁之间的女性为样本，探讨了躯干僵硬度随年龄的变化及其与长时间坐姿的关系。年龄评估为实足年龄和健康年龄，使用被动躯干屈曲仪测量躯干刚度。参与者坐在电脑工作站前60分钟，每10分钟记录一次脊柱姿势。研究发现，躯干刚度随着年龄的增长而显著增加，特别是考虑到健身年龄（r = 0.517, p = 0.003）。此外，躯干僵硬度与坐位时脊柱运动呈负相关（r = -0.435, p = 0.023）。这些发现表明，健康状况较差的员工坐着时活动较少，更容易受到久坐工作的有害影响。

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.
