Российский кардиологический журнал № 3 (143) | 2017 THE IMPACT OF INDOOR CYCLING TRAINING ON HEMODYNAMIC PARAMETERS OF THE LEFT VENTRICLE OF MEN WITH ISCHAEMIC HEART DISEASE OR AFTER MYOCARDIAL INFARCTION Gloc D. D.1 , Nowak Z.2 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. <...> 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. <...> 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). <...> 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. <...> Russian Journal of Cardiology 2017, 3 (143): 46–53 http://dx.doi.org/10.15829/1560-4071-2017-3-46-53 Key words <...>
