The overarching goal of ergonomics is to enhance performance and ensure workplace safety during physical tasks, simultaneously minimizing musculoskeletal disorders and energy expenditure. Recently, concerns have arisen about body measurements contributing not only to musculoskeletal issues but also to a potential decline in energy and work efficiency. Hence, this study aimed to explore the impact of maximum grip strength (MGS) on activity energy expenditure (AEE) and work efficiency. AEE measurements, conducted using the Actiheart, were carried out with 10 subjects performing a drilling task in 12 coordinated postures involving the shoulder, trunk, and leg. Analysis through independent samples t-test and mean differences revealed that AEE decreased as subject's MGS increased. Individuals with higher MGS exhibited lower in AEE, suggesting greater efficiency in their performance.
