INTRODUCTION There is still unresolved question whether ischemia-inducing training regime would be superior to guideline-driven approach which recommends that training intensity should stay below the ischemic threshold( IT) . OBJECTIVES This study purpose was to assess the influence of pre-training warm-up ischemia on effects of training conducted either at or below the ischemic threshold in CAD pts. PATIENTS AND METHODS 30 male pts aged 568 yrs, after MI with stable angina and positive exercise test (ET1) were divided into 2 groups: Gr A comprised pts presenting pre-training warm-up effect (n=18), and Gr B (n=12) pts without this phenomenon. Then, all pts underwent 8-week training program (TP). The intensity of TP was planned to reach HR at ischemic threshold. Successive ETs were performed immediately after TP(ET2), on days 3 (ET3), and 10 (ET4) and one month (ET5) after TP.  RESULTS In Gr A, all analyzed variables improved significantly during ET2 compared with ET1 except max ST depression(max STD). An increase in workload was 28%, in distance 24%, in duration 20%, and in time to 1-mm-ST depression( STD)  28%. Max STD reduction, although insignificant was 14%. Beneficial effect of training on exercise-induced ischemia maintained up to 10 days (ET4) and that on physical capacity (PC) up to one month(ET5). In Gr B, TP did not influence time to 1-mm STD, yet PC improved significantly in comparison with ET1 and maintained to one month.  CONCLUSIONS Warm-up effect before exercise training appeared necessary to attenuate myocardial ischemia after training.
