“…Exercise is also associated with improved body weight, blood pressure, insulin sensitivity and hemostatic and inflammatory variables [91,92] . 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.…”

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.

“…Regardless, it is apparent the literature on the effects of interval exercise training in populations with CAD is still developing, and that further research is necessary to examine all of the possible outcomes, as well as determine regulatory pathways. No studies to date have reported adverse events during interval training in individuals with CAD, which supports the acute exercise findings by Meyer et al (1998;. Additionally, no studies reported poor compliance to the interval programs, which is supported by Bartlett et al (2011) who demonstrated interval exercise was perceived to be more enjoyable than endurance exercise.…”

“…Meyer et al (1996) observed acceptable increases in indices of cardiac stress, metabolic stress, catecholamines and leg fatigue in patients with CAD and congestive heart failure during 3 different interval bouts. This was followed up by a study that demonstrated comparable increases in heart rate, systolic blood pressure, cardiac output and leg fatigue during steady-state and interval exercise in CVD patients (Meyer et al 1998). Lastly, in an examination of interval exercise there were no post-exercise elevations in troponin T, indicating the high-intensity exercise did not elicit myocardial injury (Guiraud et al 2011).…”

The merits of low-volume high-intensity interval exercise (HIT) have been established in healthy populations; however, no studies have examined this exercise prescription in patients with coronary artery disease (CAD). The present thesis examined the acute and chronic effects of HIT in patients with CAD. The first study demonstrated transient improvements in brachial artery endothelial-dependent function, which was assessed using flow-mediated dilation (FMD) 60 min following a single bout of either HIT or moderate-intensity endurance exercise (END) in habitually active patients. The second study demonstrated no effects of training status on the acute endothelial responses to exercise; following 12-weeks of either HIT or END training. However, there was a significant reduction in endothelial-independent function immediately postexercise, at both pre- and post-training, which requires further examination. The third study demonstrated comparable increases in fitness and resting FMD following 12-weeks of END and HIT, lending support to the notion that favourable adaptations are obtainable with a smaller volume of exercise. Finally, the fourth study demonstrated no change in heart rate recovery following 12-weeks of END and HIT. However, pre-training heart rate recovery values reported by our sample were in a low risk range, which suggests training induced improvements may only be achievable in populations with attenuated pre-training values. The results of this thesis provide preliminary evidence that supports the use of HIT in patients with CAD. The findings of favourable transient and chronic improvements following HIT are notable, especially given that the HIT protocol involves less time and work than END, which was modelled after the current exercise prescription in cardiac rehabilitation. Further investigations are necessary, including the assessment of additional physiological indices; the feasibility and adherence to HIT; the inclusion of CAD populations with comorbidities, including heart failure and diabetes; as well as other forms of HIT training, including HIT combined with resistance training.

Purpose:Regular exercise training induces cardiac physiological hypertrophy. The aim of this study was to determine the effect of aerobic continuous training and a detraining period on left ventricular structure and function in non-athlete healthy men. Material:Ten untrained healthy male students (aged 18-22 years) were volunteered and participated in countryside continuous jogging programme (3days/week, at 70% of Maximum Heart Rate for 45 min, 8-weeks) and four weeks detraining afterwards. M-mode, 2-dimensional, colour and Doppler transthoracic echocardiography were performed, during resting conditions, before and after the training and after detraining period. Results:Using t-test, we found significant difference in end systolic diameter and the posterior wall thickness, percentage shortening and ejection fraction after eight weeks training compared to before training. It was found no significant difference in end diastolic diameter, interventricular septum thickness, left atrium diameter, aortic root diameter, heart rate, systolic and diastolic blood pressures. Following four weeks detraining after training, compared with eight weeks of training was a significant difference in end diastolic diameter, percentage shortening and ejection fraction and no significant difference in end systolic diameter, posterior wall thickness, interventricular septum thickness, left atrium diameter, aortic root diameter, heart rate, systolic and diastolic blood pressures. Conclusions:In general, eight-week aerobic continuous training and a detraining period can affect left ventricular structure and function.
