Abstract

Inertial measurement units (IMUs) represent an exciting opportunity for researchers to broaden our understanding of running-related injuries, and for clinicians to expand their application of running gait analysis. The primary aim of our study was to investigate the 1-week (short-term) and 3-month (long-term) reliability of peak resultant, vertical, and anteroposterior accelerations derived from insole-embedded IMUs. The secondary aim was to assess the reliability of peak acceleration variability and left-right limb symmetry in all directions over the short and long term. A sample of healthy adult rearfoot runners (n = 23; age 41.7 ± 11.2 years) ran at a variety of speeds (2.5 m/s, 3.0 m/s, and 3.5 m/s) on a treadmill in standardised footwear with insole-embedded IMUs in each shoe. Peak accelerations exhibited good to excellent short-term reliability and moderate to excellent long-term reliability in all directions. Peak acceleration variability showed poor to good short- and long-term reliability, whereas the symmetry of peak accelerations demonstrated moderate to excellent and moderate to good short- and long-term reliability, respectively. Our results demonstrate how insole-embedded IMUs represent a viable option for clinicians to measure peak accelerations within the clinic.

跑步机跑步过程中内置鞋垫惯性测量装置的一周和三个月加速度结果的可靠性。

惯性测量单元（IMU）为研究人员提供了一个激动人心的机会，可以拓宽我们对跑步相关损伤的理解，也可以为临床医生扩展他们在跑步步态分析方面的应用。我们研究的主要目的是研究鞋垫嵌入式IMU产生的峰值合成加速度、垂直加速度和前后加速度的1周（短期）和3个月（长期）可靠性。次要目的是评估短期和长期内所有方向上峰值加速度变异性和左右肢体对称性的可靠性。健康成年后足运动员的样本（n = 23；年龄41.7±11.2 年）以各种速度（2.5 m/s，3.0 m/s和3.5 m/s）在跑步机上，在每只鞋中嵌入鞋垫IMU。峰值加速度在所有方向上都表现出良好到极好的短期可靠性和中等到极好的长期可靠性。峰值加速度变异性表现出较差至良好的短期和长期可靠性，而峰值加速度的对称性分别表现出中等至良好和中等至良好的近期和长期可靠性。我们的研究结果表明，鞋垫嵌入式IMU是临床医生在临床上测量峰值加速度的可行选择。

期刊介绍： Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
