“…These expected effects conform to previous results showing that prolonged standing induce long-lasting muscle fatigue (Garcia et al, 2015(Garcia et al, , 2016(Garcia et al, , 2018Wall et al, 2020), edema Antle et al, 2018;Garcia et al, 2018;Hansen et al, 1998;Wall et al, 2020;Zander et al, 2004), and discomfort (Garcia et al, 2015(Garcia et al, , 2018, Drury et al, 2008. However, in this field study, lower-leg muscle fatigue and edema were not yet significant after 6 hr of standing work, when wearing regular socks, while these effects were seen to appear within 3 hr of static standing work at an office workstation Garcia et al, 2015Garcia et al, , 2016Garcia et al, , 2018Wall et al, 2020). In this latter condition, lowerleg muscle fatigue was strongly present after 3 hr of light manual work including various rest break distributions (Garcia et al, 2015(Garcia et al, , 2016(Garcia et al, , 2018 regardless of age, gender, and habituation to standing work (Garcia et al, 2015;Wall et al, 2020); hence, these factors are not considered in the present work.…”
