This study evaluates the effects of different volumes of aerobic exercise training in cardiovascular parameters of patients with cardiovascular diseases enrolled in a cardiac rehabilitation program.
Aerobic exercise training is well known to improve endothelium dependent vasodilatation in the microcirculation. However, the impact of exercise frequency on this response in patients with coronary artery disease remains unclear.
Study Type
OBSERVATIONAL
Enrollment
115
Patients included in the study will be enrolled in a cardiac rehabilitation program, in an independent manner of the study protocols.
Participants will remain sedentary.
