The main objective is to evaluate in hemodialysis patients the effects of two intradialytic rehabilitation programs based on physical exercise, with or without the application of blood flow restriction, on myocardial stunning and morpho-functional cardiac remodelling, compared with usual care (i.e., dialysis without exercise). In addition, the investigators will also assess the acute effects (i.e., a single session for each condition) of physical exercise, with or without blood flow restriction, on myocardial stunning at the end of dialysis.
In comparison with a conventional exercise program, the combination of physical exercise with blood flow restriction, which synergistically and additively activates intramuscular signalling pathways related to both exercise and ischaemia, is hypothesised to result in:
This is a three-arm randomised clinical trial with parallel groups: standard hemodialysis (HD-CONTChro), a rehabilitation program with intradialytic exercise without vascular occlusion (HD-EXChro), and a rehabilitation program with intradialytic exercise with vascular occlusion (HD-BFREChro), with a 1:1:1 allocation ratio.
To investigate the acute effects of the interventions, all patients will undergo, in a randomized order, one session of each of the three dialysis modalities-standard hemodialysis (HD-CONTacute), hemodialysis with exercise without vascular restriction (HD-EXacute), and hemodialysis with exercise with vascular restriction (HD-BFREacute)-prior to initiation of the chronic phase of the study.

| Change in the number of regional wall motion abnormalities (RWMAs) | The investigators will use echocardiography to assess the number of left ventricular myocardial segments (using a 18-segment model), that demonstrate a reduction in longitudinal deformation greater than 20% at peak stress during hemodialysis, relative to baseline measurements obtained at the start of the dialysis session. Their aim is to compare the change in regional wall motion abnormalities (RWMAs) at peak stress of dialysis (i.e. 30 min before its end), in a standard HD, before and after 12 weeks of program (for HD-EXChro and HD-BFREChro) or usual care (for HD-CONTChro).
