Abstract

The aim of the present study was to compare the sympathetic neural and endothelial responses of brachial artery to vasodilatory and constrictor stimuli in elite weightlifters and a sedentary age-matched control group. 7 elite weightlifters (age 23. 5± 2. 2 yrs) and 8 sedentary healthy subjects (age 24. 3± 2. 12 yrs) voluntarily participated in this study. High-resolution Doppler ultrasound was used to determine brachial artery diameters at rest, following 5 minutes of forearm occlusion [Flow Mediated Dilation (FMD)] and during acute sympathetic stimulation [cold pressure test (CPT)]. vasoreactivity responses were calculated from the vasodilatory and constrictor peak changes in artery diameter. The acquired data were analyzed using independent t test and repeated measures method at P≤ 0. 05. brachial artery diameters in baseline [mean differences, 0. 5 mm (P=0. 001)], peak vasodilation [mean differences, 0. 57 mm (P=0. 002)] and peak constriction [mean differences, 0. 498 mm (P=0. 003)] were significantly greater in weightlifters than control group. However, no significant difference was observed in %FMD, %CPT and vascular operating range (VOR) between weightlifters and age-matched control group (P≤ 0. 05). The present study indicated that the function of brachial artery is not necessarily enhanced in elite weightlifters. However, elite weightlifters had larger brachial artery diameter than age-matched healthy control subjects.
