The influence of endurance training intensity on dynamics of post-exertional heart rate recovery adaptation in patients with ischemic heart disease
The intensity of post-exertion heart rate recovery, evaluated in the first minute of the recovery period (HRR60), is considered to be a strong predictor of risk for cardiac death. Intensification of physical activity performed as part of cardiac rehabilitation (CR) increases the HRR60 value in ische...

Zusammenfassung: | The intensity of post-exertion heart rate recovery, evaluated in the first minute of the recovery period (HRR60), is considered to be a strong predictor of risk for cardiac death. Intensification of physical activity performed as part of cardiac rehabilitation (CR) increases the HRR60 value in ischemic heart disease (IHD) patients. In this context, the impact of endurance training intensity (ETI) on change in HRR60 intensity seems to be an interesting issue.
The study group consisted of 251 patients who were subjected to a CR cycle. 45 patients of this group participated in CR twice. The control group consisted of 35 patients who were not subjected to any CR. ETI was estimated by the training work. In all patients an exertion test on a treadmill was performed twice within six months, analyzing the initial and final HRR60 value and ΔHRR60.
After a six-month observation, there was a statistically significant increase in the HRR60 value (17.98±8.33/min vs. 22.72±7.72/min, p |
