Impact of endurance training conducted under hypoxia conditions on change in exercise tolerance of patients with ischemic heart disease treated with angioplasty or bypass grafting.

50 patients participated in 24 endurance trainings in normobaric hypoxia conditions. Trainings were conducted every day feom Monday to Friday and lasted about 1 hour (30 minutes for adaptation and 30 minutes of training). Intensity of each session depended on the results of first stress test but never exceeded 85% of HRmax. Before trainings they had spiroergometric treadmill stress test and blood tests. These same was after training programme. 1. Before trainings each aptient uderwent: - spiroergometric test (made by physiotherapist or nurse) according to Bruce protocol - blood tests (morphologycal parameters, lipids, Interleucine alpha, gasometic parameters, electrolytes (made by nurse in analtical laboratory) - body mass and composition (In body) After these each patient participated in 24-days trainings programme on cycloergometer in normobaric hypoxia conditions (chamber of normobaric hypoxia). a) All sessions were supervsored by physiotherapist and paramedic b) Mode of administration was group of 4 patients trained at the time c) Intensity was selected individually depending on the results of the treadmill test (at the begining of programme) d) duration of session- 1 hour (30' of adaptation, 30' of proper training) e) total duration of intervention- 24 days f) Strategies used to assess and monitor adherence to the intervention- session attendence checklists 2. Type of workout- endurance workout done on cycloergometer 3. Normobaric hypoxia conditions means that level of oxygen in the air was lower (these same as on 2000m a.s.l., it is about 16% of oxygen) but pressure of the air is these same as normal After finishing trainings patients had all examinations and tests as in first day (in normoxia condiotions). Results were compared.
