Different exercise modes result in different heart rate recovery (HRR) patterns which could be related to the greater vagal reactivation following arm compared to leg-ergometry. Heart rate recovery was calculated following maximal arm and leg-ergometry. HRR-1 following maximal arm-ergometry was significantly higher than HRR-1 post maximal and sub-maximal leg-ergometry. This ...

The vasodilator signals regulating muscle blood flow during exercise are unclear. We tested the hypothesis that in young adults leg muscle vasodilation during steady-state exercise would be reduced independently by sequential pharmacological inhibition of nitric oxide synthase (NOS) and cyclooxygenase (COX) with NG-nitro-L-arginine methyl ester (L-NAME) and ketorolac, respectively. We ...
