THE IMPACT OF INDOOR CYCLING TRAINING ON HEMODYNAMIC PARAMETERS OF THE LEFT VENTRICLE OF MEN WITH ISCHAEMIC HEART DISEASE OR AFTER MYOCARDIAL INFARCTION

Aim. Younger age of the cardiac patients somehow necessitates the use of modern forms  of physical  training,  which become alternative  and  interesting  means  to provide effective rehabilitation. One such form is endurance Indoor Cycling training. In the present study attempts to determine  the impact of 1-month Indoor Cycling training on  hemodynamic  left ventricle parameters of men  with ischemic  heart disease or after myocardial infarction were made.Material and methods. The study group consisted of 50 men under the model A of the 2nd phase  of cardiac rehabilitation (20 men of the Indoor Cycling group, IC, 20 men  rehabilitated  accordingly  to  the  recommendations  of  the  Polish  Cardiac Society — a standard group, ST and 10 people who did not participate in any cardiac rehabilitation program  — a control group, C). The average  age of all patients  was 56,60±8,25  years, the average left ventricular ejection fraction was 56%±4,00. Results. Echocardiogram   did  not  show  significant  changes after  1-month  of training in both groups undergoing comprehensive cardiac rehabilitation. Paralleled to the preliminary study in the group of patients  who refused  to participate  in the cardiac   rehabilitation,   results   showed   a  reduction   in  all  echocardiographic parameters, including a significant decrease in the  left ventricular end  diastolic diameter (52,80 vs 50,50 mm) and volume (134,85 vs 121,88 ml; both variables at p<0,001),  as well as in the left ventricular mass (239,46 vs 208,61 g; p=0,002) and the left ventricular mass index (123,52 vs 107,61 g/m2; p=0,001).Conclusion. No negative influence of the Indoor Cycling training on morphological parameters of the left ventricle was observed. Indoor Cycling training in the second phase  of cardiac  rehabilitation  in patients  with ischemic  heart  disease or after myocardial infarction is a safe form of therapy and therefore  may be an interesting alternative method to the classic bicycle ergometer exercise in the stage of an early cardiac rehabilitation

THE IMPACT OF INDOOR CYCLING TRAINING ON EXERCISE CAPACITY AND BLOOD LIPID PROFILE OF MEN WITH ISCHAEMIC HEART DISEASE OR AFTER MYOCARDIAL INFARCTION

Aim. In the present study attempts to determine the impact of 1-month Indoor Cycling training on exercise capacity and blood lipid profile were made.Material and methods. The study group consisted of 50 men under the model A of the 2nd phase of cardiac rehabilitation (20 men of the Indoor Cycling group, IC, 20 men rehabilitated accordingly to the recommendations of the Polish Cardiac Society — a standard group, ST and 10 people who did not participate in any cardiac rehabilitation program — a control group, C). The average age of all subjects was 56,60±8,25 years, the average left ventricular ejection fraction was 56%±4,00.Results. In the IC group there was a significant increase in the test duration (8,47 vs 10,23 min; p<0,001), a significant increase in the MET value (10,86 vs 12,35; p=0,06) and VO2 max (38,43 vs 48,25 ml/kg/min; p<0,001). Parallel changes were observed in the ST group, where the following parameters improved: the test duration (8,51 vs 9,96; p<0,001), MET value (10,57 vs 12,18; p=0,002) and VO2 max (38,42 vs 46,24; p<0,001). No significant changes in rest and maximum heart rate as well as systolic and diastolic blood pressure parameters were found. In C group no significant changes in treadmill exercise test parameters were observed. Alike in the IC, ST as well as in the C group, positive modification of blood lipid profile was observed. The significant increase in the average value of HDL cholesterol in the control group (41,00 vs 49,52 mg/dl; p<0,05) was only found.Conclusion. Indoor Cycling training in the second phase of cardiac rehabilitation is a safe form of therapy and therefore may be an interesting alternative method to the classic bicycle ergometer exercise in the stage of an early cardiac rehabilitation
