Data are expressed as mean ± SD. Significance for an effect of sitting time (baseline vs 1, 2, 3, 4, 5, 6, 7, 8 h of sitting) or elastic garment (without or with) was quantified with a two-way ANOVA for repeated measures, followed by, when appropriate, Bonferroni post hoc testing was conducted.
*P < 0.05 between baseline and sitting within group.
†P < 0.05 between without garment leg and with garment leg at the same time point.
