Arterial blood flow and shear rate. Blood flow (A) and shear rate (B) of the dorsal metatarsal artery in the control (without garment, open symbols) and garment (closed symbols) legs as measured by Doppler ultrasonography before and during 8-h constant sitting. C and D, Correlations of percent changes in blood flow of the dorsal metatarsal artery with percent changes in the circumferences of the calf (C) and malleolus (D) in the control (open symbols) and garment (closed symbols) legs after 8-h constant sitting. A and B, Group data expressed as the mean ± SD, C and D, individual data of nine healthy males. A and B, Significance for an effect of sitting time (baseline vs 1, 2, 3, 4, 5, 6, 7, and 8 h of sitting) or elastic garment (with or without) was quantified with a two-way ANOVA for repeated measures, followed by Bonferroni post hoc testing as appropriate. C and D, Spearman correlations of changes in blood flow of the dorsal metatarsal artery with changes in calf (C) and malleolus (D) circumferences after 8-h constant sitting were determined. *P < 0.05 between baseline and each time point of sitting within a group; †P < 0.05 between the control and garment legs at the same time point.
