title: Acute Cardiovascular and Hemodynamic Responses to Low Intensity Eccentric Resistance Exercise with Blood Flow Restriction.
abstract: BACKGROUND
  Recently it has been suggested that low intensity (LI) resistance exercise (RE) alone or in combination with blood flow restriction (BFR) can be applied for cardiovascular function improvement or rehabilitation.
  
  
  OBJECTIVE
  The aim of the present study was to investigate the acute effects of LI eccentric RE with and without BFR on heart rate (HR), rate pressure product (RPP), blood pressure (BP) parameters [systolic, diastolic, and mean arterial pressure (MAP)], oxygen saturation (SpO2) and rate of perceived exertion (RPE).
  
  
  METHODS
  In a semi-experimental study 16 young adults (26.18 ± 3.67 years) volunteered and performed LI (30% maximum voluntary contraction) eccentric RE alone or combined with BFR.
  
  
  RESULTS
  The results indicated that HR, RPP, and RPE increased significantly within both groups (P < 0.05); SBP and DBP increased significantly only with BFR (P < 0.05); MAP increased significantly during exercise without BFR (P < 0.05); and no change was observed in SpO2in either groups (P > 0.05). Furthermore, studied parameters did not vary amongst different groups (P > 0.05).
  
  
  CONCLUSIONS
  It is concluded that LI eccentric RE with BFR positively regulated the hemodynamic and cardiovascular responses. Therefore, the eccentric RE combined with BFR seems to be a good option for future studies with the aim of time efficacy, since it alters these parameters within normal values.
