Effect of Concurrent Training on Hemodynamic Responses in Male Patients with Coronary Artery Disease

rehabilitation, mostly because of its positive effec ts on myocardi al perfu sion in patient with co ronary artery disease. Improvement of peripheral vascular sys tem and myocardi al contrac tile function hav e been suggested as potential adaptations. The purp ose of this study was to determine the effect of concurrent training 0 11 hemodynamic respon ses in patient s with coronary arte ry di sease. Materials & Methods: In this interventional and experimental study twenty four patient (50-75 years old) with coron ary artery disease were se lec ted by sample of co nve nie nce and through a directive goa l oriented sampling and were randomly divided to two subgroups. experi mental (n=12) and co ntrol (n=12) groups. The experimental group participated in 3 months co ncurre nt train ing. 3 times/w eek for 60 to 80 minute at 70% to 85% of MHR and 40% to 60% of IRM. Invest igation variables were assessed at baseline and at the end of the protocol by the impedance ca rdiography meth od. Data were ana lyzed by T test. Results: A significant training effect was docum ented by an decrease in heart rate and blood pressur e at rest. Stroke volume (SV) increased from 60±8 to 81± 13 rnl/beats, Stroke index (Sl) inc reased from 33±4 to 44±6 rnl/beat/m ʹ , Cardi ac output (CO) increased from4± I to 5± I lImin and Cardiac index (Cl) increased from2±O.5 to 3±O.5 11minlm2 (p
