Indoor cycling training in rehabilitation of patients after myocardial infarction

Background Standard endurance training used from the second stage of cardiac rehabilitation has many common features with indoor cycling training which is used in fitness clubs. In the study, an attempt was made to evaluate the usefulness of this form of training in a 24-day rehabilitation program for patients after myocardial infarction. The study examined a group of 64 patients (51.34 +/- 8.02 years) who were divided into two groups: the IC group (32 patients aged 53.40 +/- 4.31 years) with indoor cycling training instead of standard endurance training; and the ST group (32 patients aged 55.31 +/- 6.45 years) performing standard training. The level of exercise tolerance (cardiopulmonary exercise testing on a treadmill-Bruce's protocol), hemodynamic indicators of the left ventricle (echocardiography) and blood lipid profile (laboratory test) were assessed. Results In the IC group there was a significant increase in the test duration (9.21 +/- 2.02 vs 11.24 +/- 1.26 min; p < 0.001), the MET value (9.16 +/- 1.30 vs 10.73 +/- 1.23; p = 0.006) and VO(2)max (37.27 +/- 3.23 vs 39.10 +/- 3.17 ml/kg/min; p < 0.001). Parallel changes were observed in the ST group, where the following parameters improved: the test duration (9.41 +/- 0.39 vs 10.91 +/- 2.22; p < 0.001), MET value (8.65 +/- 0.25 vs 9.86 +/- 1.12; p = 0.002) and VO(2)max (36.89 +/- 6.22 vs 38.76 +/- 3.44; p < 0.001). No statistically significant changes were found in the hemodynamic indices of the left ventricle and the lipid profile. Also, the intergroup analysis did not show any statistical significance. Conclusion Based on the research results, it was found that 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 early cardiac rehabilitation.
