Abstract

Regular walking exercise attenuates lower-limb
cutaneous microvascular endothelial dysfunction in postsurgical
varicose-vein patients. This study assessed the
effects of upper-limb exercise training on lower-limb cutaneous
microvascular function in this patient group. Six
post-surgical (4–5 weeks) varicose-vein patients completed
an 8-week arm-crank exercise training programme.
Changes in cutaneous microvascular function of the lower
leg were assessed using laser Doppler Xowmetry
and iontophoretic administration of endothelial-dependent
and -independent agonists [acetylcholine (ACh) and sodium
nitroprusside (SNP), respectively]. At 8 weeks, median
lower-limb cutaneous vasodilator responsives to ACh and
SNP remained unchanged relative to baseline (e.g. 6 mC:
37 (interquartile range 24–63) vs. 40 (20–71) PU and 35
(23–48) vs. 38 (21–64) PU, respectively for the supine
position). Upper-limb exercise appears ineffective for
improving lower-limb cutaneous microvascular function in
post-surgical varicose-vein patients. Therefore, limb speci-
ficity appears an important factor in optimal exercise
prescription for these patients.
