Abstract

<p>Fatigue among ship operators has been reported as a reason for marine accidents. Thus, the causes of fatigue should be investigated. Our previous study found that crews control their posture by leveraging pitch motions at their waist using their lower limbs, which affects energy expenditure - an indicator of physical fatigue. This study aims to reveal the relationship between the crew's energy expenditure and their muscle activities by measuring their surface myoelectric signals. The surface myoelectric signals of eight participants in a small marine craft were measured at the soleus, vastus lateralis, lumbar paraspinals, and cervical paraspinals. By using multiple regression analysis, the lumbar paraspinals and body surface area were determined to especially affect energy expenditure, and these partial regression coefficients were 0.30 and 0.84, while the coefficient of determination was 0.98. This study suggests a correlation between the participants' lumbar paraspinals in maintaining posture and their energy expenditure.</p>
