Asymmetrical external loading acting on the musculoskeletal system is generally considered unhealthy. Despite this knowledge, carrying loads in an asymmetrical manner like carrying on one shoulder, with one hand, or on the strap across the torso is a common practice. This study is aimed at presenting the effects of the mentioned load carrying methods on muscle activity assessed by using thermal field and ground reaction forces. Infrared thermography and pedobarographic force platform (ground reaction force/pressure measurement) were used in this study. Experimental results point out an increased load-dependent asymmetry of temperature distribution on the chosen areas of torso and the influence of external loading on ground reaction forces. Results point out that wearing an asymmetrical load should be avoided and are showing which type of carrying the external load is potentially less and the most harmful.
作用于肌肉骨骼系统的不对称外部负荷通常被认为是不健康的。尽管有这样的认知，但以不对称方式负重，如单肩扛、单手拎或用横跨躯干的背带负重，却是常见的做法。本研究旨在呈现上述负重方式对通过热场和地面反作用力评估的肌肉活动的影响。本研究使用了红外热成像技术和足底压力测力平台（地面反作用力/压力测量）。实验结果表明，在选定的躯干区域，温度分布的不对称性随负荷增加，且外部负荷对地面反作用力有影响。结果指出应避免不对称负重，并表明哪种外部负重方式潜在危害较小和最大。
