“…They found that carrying a distributed load induced significantly higher HR responses than a compact load. In addition to HR, EDA is an important measure to assess exertion during physical and mental workload (Epps, 2018; Collet et al , 2014; Anwer et al , 2020). While many ergonomic studies have used EDA to objectively quantify mental fatigue (Gevins and Smith, 2003; Reimer and Mehler, 2011; Just et al , 2003), no study has used EDA to measure physical exertion during different load-carrying tasks, which may provide new insight into physiological changes.…”

“…However, these studies only assessed energy expenditure or oxygen consumption that may lead to exertion. Recently, heart rate (HR) and electrodermal activity (EDA) have been found as important indicators of physical and mental exertion (Epps, 2018; Collet et al , 2014; Anwer et al , 2020). Furthermore, carrying a load in one hand corresponds to a higher HR than carrying a load in two hands (Irion et al , 2010).…”

“…This segmentation correlates with understimulation leading to disengagement, optimal arousal corresponding to peak performance, and overarousal resulting in stress or errors. Both disengagement and excessive stress can negatively impact accuracy, productivity, and multitasking capabilities, highlighting the need for a delicate balance to maintain team efficacy [9,10].…”

“…The relationship between task load and performance, with the task load scale derived from the NASA-TLX as a percentage. Performance varies with task load, where lower performance is associated with disengagement (task load < 33%), optimal performance corresponds to peak engagement (task load 33-66%), and higher task load leads to stress and reduced performance (task load > 66%) [1,8,10].…”
