Abstract

Introduction: In this study, we used surface electromyography (EMG) electrodes in order to measure and compare activity in the neck, back and thigh muscles of soldiers wearing two different types of body armour. A secondary objective was to analyse shoulder and hip ranges of motion using inertial motion sensors.

Methods: Fourteen male soldiers were instructed to march 6 km on a treadmill while wearing different types of body armour. All participants wore shorts and a T-shirt and the same size vest regardless of their body size. We measured back and thigh muscle activity as well as shoulder and hip ranges of motion at regular intervals during the march.

Results: Over the course of a 6 km march, muscle activity was already increased to 1.3 to 2.0 times after putting on the vest and increased by up to 13 times during the march with equipment. The new vest with hip belt required higher levels of muscle activity.

Conclusions: Body armour with hip belt placed higher levels of stress on back and neck muscles during a 6 km march than without. There was no major difference between the two types of body armour in terms of thigh muscle activity.

Trial registration number: DRKS00016005.

对穿着不同类型防弹衣的德国士兵行军时的肌电图和运动范围进行测量。
简介在这项研究中,我们使用表面肌电图(EMG)电极来测量和比较穿着两种不同类型防弹衣的士兵的颈部、背部和大腿肌肉活动情况。次要目标是使用惯性运动传感器分析肩部和臀部的运动范围:方法:14 名男性士兵被要求穿着不同类型的防弹衣在跑步机上行进 6 公里。所有参与者都穿着短裤、T恤和相同尺寸的防弹背心,与体型无关。在行进过程中,我们定时测量背部和大腿肌肉活动以及肩关节和髋关节的活动范围:结果:在 6 公里的行进过程中,穿上背心后肌肉活动量已增加了 1.3 至 2.0 倍,而在穿戴装备行进过程中,肌肉活动量最多增加了 13 倍。结论:结论:在 6 公里行军过程中,带臀带的防弹背心对背部和颈部肌肉造成的压力高于不带臀带的防弹背心。在大腿肌肉活动方面,两种类型的防弹背心没有很大区别:DRKS00016005.
