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<0.05) and increased CBF (p<0.01). Also, IES was associated with a greater reduction on the MMA (IES: 9 ± 2, TENS: 14 ± 4, Sham: 26 ± 5 units; p<0.01). Furthermore, the IES group had a higher reduction of LF/HF ratio during PECO- and PECO+ (p<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. </p>}, journal={Manual Therapy, Posturology & Rehabilitation Journal}, author={Chiappa, Gaspar Rogerio da Silva and Zago, Julio and Vieira, Paulo and Winter, Andre and Winter, André and Chiappa, Adriana and Rondinel, Tatiana and Santos, Francisco and Cipriano, Gerson and Silveira, Marcos}, year={2021}, month={Dec.}, pages={1–7} }
