摘要

负重任务中的步态生物力学是军事研究的重点，旨在优化性能和管理伤害风险。然而，在这些任务中，武器操作对步态的影响仍然相对未被探索。本研究探讨了非线性步幅时间测量，特别是去趋势波动分析（DFA）和样本熵（SE），以评估步幅时间的持续性和规律性。17名澳大利亚陆军士兵在仪器跑步机上完成了12分钟的步行试验，携带和不携带仿制步枪，同时以3.5公里/小时、5.5公里/小时和6.5公里/小时的速度携带23.2公斤的负荷。脚后跟接触使用18个摄像头的Vicon系统进行跟踪。混合效应模型分析表明，武器操作对跨步时间变异性（DFA p = 0.46）或规律性（SE p = 0.42）没有显著影响，这表明它可能不是未来研究负重任务中跨步时间变异性的关键因素。

Carrying a weapon does not change stride-time variability during treadmill-based load carriage.

Gait biomechanics during load carriage tasks are a focus of military research aiming to optimise performance and manage injury risk. However, the impact of weapon handling on gait during these tasks remains relatively unexplored. This study investigates non-linear stride time measures, specifically detrended fluctuation analysis (DFA) and sample entropy (SE), which assess the persistence and regularity of stride time. Seventeen Australian Army soldiers completed 12-minute walking trials on an instrumented treadmill, both with and without a replica rifle while carrying 23.2 kg of load at speeds of 3.5 km/h, 5.5 km/h, and 6.5 km/h. Heel contacts were tracked using an 18-camera Vicon system. Mixed-effect model analyses indicated that weapon handling did not significantly affect stride time variability (DFA p = 0.46) or regularity (SE p = 0.42), suggesting it may not be a critical factor in future studies of stride time variability during load carriage tasks.

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.
