The acute intervention was applied on stellate ganglion region (C7-T4). <strong>Results:</strong> Were measured metaboreflex activity by calf vascular resistance (CVR) and calf blood flow (CBF) and HRV during three times: rest, exercise (static handgrip) and postexercise circulatory occlusion (PECO+ and PECO-). At the exercise peak, compared with TENS and Sham, the IES group reduced CVR (36 ± 3 vs 43 ± 3; p&lt;0.05) and increased CBF (p&lt;0.01). Also, IES was associated with a greater reduction on the MMA (IES: 9 ± 2, TENS: 14 ± 4, Sham: 26 ± 5 units; p&lt;0.01). Furthermore, the IES group had a higher reduction of LF/HF ratio during PECO- and PECO+ (p&lt;0.05). <strong>Conclusion:</strong> The IES over the stellate ganglion region seems to have superior efficacy compared with TENS to attenuate metaboreflex activation and vasodilatory responses during exercise in healthy subjects.&nbsp;</p> ER -
