Perfusion (ml/min-100 g)	(n = 14)	(n = 12)	(n = 15)	(n = 11)
Anterior compartment	52 ± 39	61 ± 33	33 ± 20	26 ± 24
Lateral compartment	44 ± 24	75 ± 27	26 ± 13	16 ± 15
Lateral gastrocnemius	38 ± 35	75 ± 14	6 ± 8	21 ± 16
Medial gastrocnemius	48 ± 24	127 ± 50	15 ± 11	22 ± 17
Soleus	9 ± 8	179 ± 60	13 ± 11	81 ± 59
Deep compartment	18 ± 21	95 ± 60	11 ± 15	28 ± 30
Maximal perfusion	74 ± 21	179 ± 60^†	43 ± 10^†,‡	92 ± 55^†,‡
Average perfusion	-	109 ± 40	-	36 ± 19^‡

^†p < 0.05 vs. NL-Ex; ^‡p < 0.05 vs. NL-Cuff. NL = healthy controls; PAD = peripheral arterial disease patients; Ex = exercise stress; Cuff = occlusion-hyperemia stress.
