nomic nervous system alterations. The aim of the study was to assess the contribution of the metaboreflex to the control of blood pressure
and heart rate in individuals with MR and ND individuals.
Methods: Eleven healthy ND males (25.1±0.5 years) and ten healthy males with MR (26.4±5.5 years) volunteered for the study. The responses
to isometric handgrip (HG) exercise and the persistence of active metaboreflex via local post exercise circulatory occlusion
(PECO) were evaluated. The testing protocol involved a 3-min rest period, 3 min HG exercise at 30%MVC, followed by 3 min of postexercise
circulatory occlusion and 3 min of recovery (+PECO protocol). Following a 45-min rest, the same protocol was repeated without
circulatory occlusion (-PECO protocol). Beat to beat blood pressure (Finometer) and heart rate were measured non-invasively throughout
the protocol.
Results: Significant differences (p
