“…An improvement of endothelial dysfunction, assessed sonographically, was also noted after interval exercise training. 18 The second main finding of our study was that microcirculation abnormalities in CHF were significantly correlated with strong prognostic indicators derived from CPET. The degree of reduced RR was associated with reduced exercise capacity (VO 2 peak), inefficient ventilatory capacity (VE/VCO 2 slope) and impaired parasympathetic activity (HRR 1 ), all powerful prognostic indices in CHF, 15,19 which can be improved after exercise training.…”

“…High-intensity interval training is a relative novel alternative modality of exercise in metabolic syndrome [93] , coronary heart disease [94] and in CHF patients [95][96][97] , allowing more intense stimuli in the peripheral muscles. The addition of strength training has been also shown to confer significant improvement in endothelial function [98,99] and peripheral microcirculation [100] in CHF patients.…”

“…A structured exercise training program, and more specifically a combination of aerobic exercise (continuous or high-intensity interval training) with or without the addition of strength training can significantly attenuate the atherosclerotic process through its beneficial effects on endothelial function [93,95,[98][99][100] . However, there is growing interest concerning the role of exercise training on EPCs that may interact with endothelium function; this issue is currently under investigation from several research groups in both healthy subjects and diseases.…”

Circulating bone-marrow-derived cells, named endothelial progenitor cells (EPCs), are capable of maintaining, generating, and replacing terminally differentiated cells within their own specific tissue as a consequence of physiological cell turnover or tissue damage due to injury. Endothelium maintenance and restoration of normal endothelial cell function is guaranteed by a complex physiological procedure in which EPCs play a significant role. Decreased number of peripheral blood EPCs has been associated with endothelial dysfunction and high cardiovascular risk. In this review, we initially report current knowledge with regard to the role of EPCs in healthy subjects and the clinical value of EPCs in different disease populations such as arterial hypertension, obstructive sleep-apnea syndrome, obesity, diabetes mellitus, peripheral arterial disease, coronary artery disease, pulmonary hypertension, and heart failure. Recent studies have introduced the novel concept that physical activity, either performed as a single exercise session or performed as part of an exercise training program, results in a significant increase of circulating EPCs. In the second part of this review we provide preliminary evidence from recent studies investigating the effects of acute and long-term exercise in healthy subjects and athletes as well as in disease populations.

“…Just recently, we have shown that the addition of strength training to the interval training regimen in CHF patients confers more beneficial effects in terms of muscle strength [9] and endothelial function [26], than interval training alone. However, in the present study, there was no significant difference in tissue oxygenation indices between the two training groups.…”

Aim: Aim of our study was to evaluate the effects of interval exercise training (IT) programs, regarding whole body oxygen uptake and peripheral tissue oxygenation, in Chronic Heart Failure (CHF) patients during recovery. Methods: Twenty-six CHF patients (21 males/5 females), mean age of 49 ± 12 years, participated in the study. Fifteen patients were assigned to IT and 11 patients were assigned to IT followed by strength training. All patients were trained for 40 minutes per session, 3 times per week, for 12 weeks. They performed a symptom-limited cardiopulmonary exercise testing (CPET), before and after the completion of the program. Muscle tissue oxygen saturation (StO 2 ) of quadriceps femoris was continuously measured by Near Infrared Spectroscopy (NIRS) during CPET and during the recovery period after the end of exercise. Results: No differences were noted between the two patient groups regarding whole body and peripheral tissue oxygenation indices and, therefore, data from all patients were pooled. After training, an increase in peak oxygen uptake (17 ± 4.5 to 19 ± 5.5 ml/kg/min, p < 0.05), gas exchange threshold (11 ± 3.5 to 12.5 ± 3.5 ml/kg/min, p < 0.05), peak work rate achieved (105 ± 29 to 124 ± 37 Watt, p < 0.05) and the first degree slope of VO 2 at the first minute of recovery (0.45 ± 0.2 to 0.61 ± 0.3 L/min 2 , p < 0.05), was noted. In addition, tissue re-oxygenation time constant was decreased (65 ± 25 to 52 ± 28 sec, p < 0.001). Conclusion: In conclusion, interval exercise training accelerates oxygen uptake and peripheral tissue oxygenation during recovery from exercise in CHF patients.
