Use of cold-weather personal protective clothing (PPC) in cold climates is essential but can add metabolic cost to the wearer. This study measured the effect of wearing state-of-the-art PPC and personal protective equipment (PPE), with the possible effect of clothing layers and fit, on physiological responses including metabolic rate (MR) and muscle activation level. 19 male participants (80.2 ± 5.9 kg, 181.5 ± 5.1 cm) wore five different clothing ensembles during level (0°) and inclined (6°) walking. Compared to a base layer ensemble (388.7 ± 42.7 W/737.8 ± 57.9 W), wearing a 3-layer PPC ensemble (421.5 ± 44.7 W/811.7 ± 69.2 W) significantly increased MR, and adding PPE (458.3 ± 59.8 W/864.5 ± 71.2 W) further increased MR during level/inclined walking. Independent of the extra weight, adding a middle layer between base layer and outer clothing significantly increased MR during inclined walking only, and no effect of oversized outer clothing was measured.
在寒冷气候下使用防寒个人防护服（PPC）至关重要，但这会增加穿着者的代谢成本。本研究旨在测量穿着最先进的 PPC 和个人防护设备（PPE）的效果，包括服装层数和贴合度对代谢率（MR）和肌肉激活水平等生理反应的影响。19 名男性参与者（80.2±5.9kg，181.5±5.1cm）在水平（0°）和倾斜（6°）行走时穿着五种不同的服装套装。与基础层服装套装（388.7±42.7W/737.8±57.9W）相比，穿着三层 PPC 服装套装（421.5±44.7W/811.7±69.2W）显著增加了 MR，而添加 PPE（458.3±59.8W/864.5±71.2W）则进一步增加了在水平/倾斜行走时的 MR。无论额外的重量如何，在基础层和外层服装之间添加中间层仅在倾斜行走时显著增加了 MR，并且没有测量到过大的外层服装的影响。
