Key result
Application of 35 mmHg lower body positive pressure during dynamic exercise augmented the release of arginine vasopressin and catecholamines, but not plasma renin activity.

No immediate clinical implications; leaves open whether metaboreflex thresholds differ among vasopressin, catecholamines, and renin.
Does moderate muscle metaboreflex activation via lower body positive pressure augment the release of arginine vasopressin, plasma renin activity, and catecholamines during dynamic exercise in healthy adults?
Moderate activation of the muscle metaboreflex during dynamic exercise augments the release of arginine vasopressin and catecholamines, but not plasma renin activity, suggesting non-uniform thresholds for hormonal responses.
Nishiyasu et al. (2000) studied Healthy adults (n=10). Lower body positive pressure (LBPP) vs. Exercise without LBPP was evaluated on Arginine vasopressin, plasma renin activity, and catecholamines. Application of 35 mmHg lower body positive pressure during dynamic exercise augmented the release of arginine vasopressin and catecholamines, but not plasma renin activity.
