Low-load resistance training with blood flow restriction prevent renal function decline: The role of the redox balance, angiotensin 1–7 and vasopressin

•Resistance exercise is an adjunct in the control of hypertension in renal patients.•Strength exercise antagonizes the increase in ADMA induced by chronic kidney disease.•Blood flow restriction is a method that maximizes the exercise benefits in chronic kidney disease patients.•Angiotensin 1–7 and vasopressin are regulated by exercise with restricted blood flow. We sought to investigate the effect of resistance training (RT) and low-load RT with moderate blood flow restriction (RT+BFR) on blood pressure, exercise pressor response, redox balance and vasoactive peptides, body composition and muscle strength in patients with stage two of chronic kidney disease (CKD). We conducted a 6-month randomized controlled exercise intervention in 90 male and female hypertensive CKD patients (58±9 years with estimated glomerular filtration rate (eGFR; of 66.1 ± 1.2 mL/kg/1.73m2). Participants were randomized to one of three groups (n = 30/group); control group (CTL), RT, and RT+BFR. RT and RT+BFR performed three weekly training sessions using similar periodization for six months (two-month mesocycles), but of different intensities. There was similarly effects between RT and RT+BFR in reducing systolic and diastolic blood pressure during daytime and 24hour period (RT: 10.4%; RT+BFR: 10.3% of decrease), fat mass, F2-isoprostanes, asymmetric dimethylarginine (ADMA) and vasopressin (p
