Abstract
Cardiovascular (CV) morbidity and mortality is high in patients with chronic kidney disease (CKD). Most patients reveal a high prevalence of CV risk factors such as diabetes or arterial hypertension and many have manifest cardiovascular disease (CVD), such as coronary artery disease and chronic heart failure with an increased risk of clinical events including sudden cardiac death. Diabetes mellitus and hypertension contribute to the development of CKD and the prevalence of CKD is in the range of 20%-65% in diabetic and 30%-50% in hypertensive patients. Therefore, prevention and optimal treatment of CV risk factors and comorbidities are key strategies to reduce CV risk and improve survival in CKD. Beyond common CV risk factors, patients with CKD are often physically inactive and have low physical function leading to subsequent frailty with muscle fatigue and weakness, sarcopenia and increased risk of falling. Consequently, the economic health burden of CKD is high, requiring feasible strategies to counteract this vicious cycle. Regular physical activity and exercise training have been shown to be effective in improving risk factors, reducing CVD and reducing frailty and falls. Nonetheless, combining exercise training and a healthy lifestyle with pharmacological treatment is not frequently applied in clinical practice. For that reason, this Clinical Consensus Statement reviews the current literature and provides evidence-based data regarding the role of exercise training in reducing CV and overall burden in patients with CKD. The aim is to increase awareness among cardiologists, nephrologists, and health care professionals of the potential of exercise therapy in order to encourage implementation of exercise training in clinical practice, eventually reducing CV risk and disease, as well as reducing frailty in patients with CKD G3 to G5D.

Abstract
This randomized clinical trial aimed to examine the effects of a 6-month home-based, combined exercise training program on Cardiac Autonomic Neuropathy (CAN) in kidney transplant recipients (KTRs) with diabetes. Twenty-five KTRs (19 men (76.0%), with a mean age of 54.4 ± 11.3 years old, CAN and type II Diabetes Mellitus (DM-II)), were randomly assigned into two groups: A (n1 = 13 KTRs), who underwent a home-based exercise training program for 6 months, and B (n2 = 12 KTRs), who were assessed at the end of the study. A cardiopulmonary exercise testing (CPET), sit-to-stand test in 30 s (30-s STS), isokinetic muscle strength dynamometry, and 24-h electrocardiographic monitoring were applied to all participants, both at the baseline and at the end of the clinical trial. At first, there were no statistically significant differences between groups. After 6 months, group A showed higher values in exercise time by 8.7% (p = 0.02), VO2peak by 7.3% (p < 0.05), 30-s STS by 12.0% (p < 0.05), upper limb strength by 46.1% (p < 0.05), and lower limb strength by 24.6% (p = 0.02), respectively, compared to the B group. Furthermore, inter-group changes at the end of the 6-month study indicated that group A statistically increased the standard deviation of R-R intervals (SDNN) by 30.3% (p = 0.01), root mean square of successive differences between normal heartbeats (rMSSD) by 32.0% (p = 0.03), number of pairs of successive NN (R-R) intervals that differ by more than 50 ms (pNN50) by 29.0% (p = 0.04), high frequency (HF (ms2)) by 21.6% (p < 0.05), HF (n.u.) by 48.5% (p = 0.01), and turbulence slope (TS) by 22.5% (p = 0.02), and decreased the low frequency (LF (ms2)) by 13.2% (p = 0.01), LF (n.u.) by 24.9% (p = 0.04), and LF/HF ratio by 24% (p = 0.01), compared to group B. Linear regression analysis after the 6-month study showed that there was a strong positive correlation between VO2peak and SDNN (r = 0.701, p < 0.05) in group A. Moreover, multiple regression analysis showed that KTRs' participation in the exercise program showed favorable modifications to sympathovagal balance and aerobic capacity, as measured with SDNN and VO2peak, respectively. To summarize, diabetic KTRs' cardiac autonomic function and functional capacity can be improved after a home-based long-term exercise training program.

Abstract
Background: This study aimed to investigate the effects of a home-based exercise training program on Cardiac Autonomic Neuropathy (CAN) and metabolic profile in Diabetic Kidney Disease (DKD) patients undergoing maintenance hemodialysis (HD). Method: Twenty-eight DKD patients undergoing hemodialysis were randomly assigned into two groups. The exercise (EX) group followed a 6-month combined exercise training program at home, while the control (CO) group remained untrained. All participants at baseline and the end of the study underwent cardiopulmonary exercise testing (CPET), biochemical tests for glucose and lipid profile, and 24-h electrocardiographic monitoring for heart rate variability (HRV) analysis and heart rate turbulence (HRT). Results: At the end of the study, compared to the CO, the EX group showed a significant increase in serum high-density lipoprotein (HDL) by 27.7% (p = 0.01), peak oxygen uptake (VO2peak) by 9.3% (p < 0.05), the standard deviation of R-R intervals (SDNN) by 34.3% (p = 0.03), percentage of successive RR intervals higher than 50ms (pNN50) by 51.1% (p = 0.02), turbulence slope (TS) index by 18.4% (p = 0.01), and decrease in (glycated hemoglobin) HbA1c by 12.5% (p = 0.04) and low-frequency power LF (ms2) by 29.7% (p = 0.01). Linear regression analysis after training showed that VO2peak was correlated with SDNN (r = 0.55, p = 0.03) and HF (r = 0.72, p = 0.02). Multiple regression analysis indicated that the improvement of sympathovagal balance and aerobic capacity depended on patients’ participation in exercise training. Conclusion: In conclusion, a 6-month home-based mixed-type exercise program can improve cardiac autonomic function and metabolic profile in DKD patients on HD.

Abstract
BACKGROUND Physical activity (PA) improves exercise capacity, slows the decline in lung function, and enhances Quality of Life (QoL) in patients with cystic fibrosis (pwCF). OBJECTIVES The study aimed to evaluate PA and QoL among children with CF compared to healthy controls; the secondary aim was to assess the correlation between PA, QoL, and lung function (FEV1). METHODS Forty-five children and adolescents with CF and 45 age-matched controls completed two self-administered validated questionnaires: The Godin Leisure-Time Exercise Questionnaire (GLTEQ) and the DISABKIDS for QoL. Moreover, pwCF performed spirometry and multiple breath washout tests (MBW). In addition, weight, height, and BMI were recorded. The Godin Leisure-Time Exercise Questionnaire was used to evaluate physical activity; QOL was assessed using the DISABKIDS Questionnaire. The correlation of PA with QOL was assessed as well. RESULTS Mean age of the CF population was 13.22 (±4.6) years, mean BMI 19.58 (±4.1) kg/m2, mean FEV1% 91.15 ± 20.46%, and mean LCI 10.68 ± 4.08. 68% of the CF group were active, 27% were medium active, 5% were sedentary, while 83% of the control group were active and 17% were medium active. PwCF with higher PA scores showed significantly higher emotional health (r2: 0.414, p: 0.006) and total QOL score (r2: 0.372; p: 0.014). The PA score showed no significant correlation with FEV1% or LCI. CONCLUSIONS The children with CF showed satisfactory PA levels, which positively correlated to their QoL. More research is needed on the effect of increased levels of habitual physical activity to establish the decline in pulmonary function among pwCF.

Abstract
BACKGROUND Running is a common recreational activity, and the number of long-distance-race participants is continuously growing. It is well-established that regular physical activity can prevent and manage non-communicable diseases and benefit public health. Training for a long-distance race requires development of specific aerobic abilities and should generate the desired race performance. The purpose of this study was to support the training design and motivation of recreational endurance runners, by investigating whether a 14.5 km race performance of long-distance runners correlates with their cardiopulmonary indices measured in the laboratory. METHODS To examine the relationships of a 14.5 km running performance with the cardiopulmonary parameters of amateur runners, a cross-sectional study design was applied. Fifteen (eleven men and four women) recreational long-distance runners (aged 41.3 ± 9.2 years) from Northern Greece were included in the study and were evaluated in the laboratory within one week before an endurance running race-the 14.5 km Philip Road race, in Greece. The laboratory-based examinations of the athletes consisted of a comprehensive medical pre-participation screening and maximal cardiopulmonary exercise testing. RESULTS The results showed that the 14.5 km race performance time (73.8 ± 9.7 min) significantly correlated with the cardiopulmonary-exercise-testing speed-related indices at specific submaximal and maximal workloads (p < 0.01, p < 0.05), while the cardiopulmonary indices of oxygen uptake did not reliably predict race running time (p > 0.05). CONCLUSIONS There is a better correlation of the 14.5 km running performance of recreational long-distance runners with the cardiopulmonary-exercise-testing speed-related indices at specific workloads than with the indices of oxygen uptake, running economy or respiratory economy. When preparing a training strategy, amateur long-distance runners should mostly rely on specific running-speed-related laboratory data rather than on oxygen-uptake values.

Abstract
This study aimed to examine the effect of an intradialytic exercise program in combination with music on heart rate variability (HRV) indices and functional capacity in patients on maintenance hemodialysis (HD). Methods: Forty HD patients were randomized to four training groups for six months: the combined music and exercise group (Group A), the exercise group (Group B), the music group (Group C), and the control group (Group D). At baseline and after 6 months, all participants underwent both short- (for 30 min) and long- (for 24 h) term measurements of HRV and functional capacity assessment with a 6 min walking test (6MWT). Patients of groups A and C listened to preferred music. Results: Long-term HRV analysis showed that standard deviation of all normal-to-normal RR intervals (SDNN) and the square root of the mean squared differences of successive RR intervals (rMSSD) were significantly higher at the end of the study in groups A (by 13.2% and 47.3%), B (by 15.1% and 50%), and C (by 9.0% and 30.1%), compared to group D (p < 0.05). Values of rMSSD and percentage of RR intervals differing by more than 50 ms from the preceding RR interval (pNN50) were elevated in groups A (by 35.6% and 142.9%), B (by 36.1% and 75%), and C (by 15.2% and 28.6%), compared to baseline measurements (p < 0.05). Also, pNN50 was increased in group A compared to groups B (by 21.4%), C (by 88.9%), and D (by 142.9%) (p < 0.05). Similar results were noted by short-term HRV analysis. Functional capacity was improved at the end of the 6-month study in groups A (by 20.3% and 25.7%) and B (by 15.8% and 21.1%) compared to groups C and D (p < 0.05). Conclusions: Intradialytic exercise combined with music-listening can improve the functional capacity and cardiac autonomic nervous system activity in hemodialysis patients.

Abstract
BACKGROUND Physical activity levels are significantly lower in kidney transplant (KT) recipients compared to the general population. The effects of exercise training in KT recipients with diabetes mellitus remain unclear, and so little is known about the role of increased exercise on cardiovascular risk and metabolic profile of KT patients.
AIM To investigate the effects of a 6-mo home-based exercise training program on functional capacity, glucose levels and lipid profile of diabetic KT patients.
METHODS In total, 21 type II diabetic KT recipients were randomly assigned into two groups: Exercise (n = 11, aged 52.9 ± 10.1 years) and control (n = 10, aged 53.01 ± 9.5 years). All participants at baseline and the end of the study underwent biochemical tests for fasting plasma glucose levels, glycated hemoglobin and lipid profile and cardiopulmonary exercise testing for maximum oxygen uptake [(VO2)peak] estimation. The exercise group followed a 6-mo supervised home-based aerobic and progressive resistance exercise program of moderate intensity 3 times per week, while the control group continued to receive usual care.
RESULTS At the end of the 6-mo study, the exercise group had significantly lower values in fasting plasma glucose by 13.4% (from 120.6 ± 28.9 mg/dL to 104.8 ± 21.9 mg/dL, P = 0.01), glycated hemoglobin by 1.5% (from 6.7% ± 0.4 to 6.6% ± 0.4, P = 0.01) and triglycerides by 8.5% (from 164.7 ± 14.8 mg/dL to 150.8 ± 11.6 mg/dL, P < 0.05) and higher values in high-density lipoprotein by 10.2% (from 51.4 ± 8.8 mg/dL to 57.2 ± 8.7 mg/dL, P < 0.05) and (VO2)peak by 4.7% (from 22.7 ± 3.3 to 23.8 ± 4.2, P = 0.02) than the control group. There were statistically significant differences between the two groups at the end of the study for fasting plasma glucose (decreased by 9.6%, P < 0.05), triglycerides (decreased by 4.5%, P = 0.04) and (VO2)peak (increased by 4.4%, P = 0.01). Finally, after training, there was a moderate, positive linear relationship between (VO2)peak and glycated hemoglobin in the exercise group (r = 0.408, P = 0.03).
CONCLUSION The results demonstrated that a 6-mo home-based mixed type exercise training program can improve the functional capacity, levels of glucose and lipid profile of diabetic KT recipients.

Abstract
Several studies have shown that patients with cystic fibrosis (CF), even at a young age, have pulmonary and cardiac abnormalities. The main complications are cardiac right ventricular (RV) systolic and/or diastolic dysfunction and pulmonary hypertension, which affects their prognosis. Exercise training (ET) is recommended in patients with CF as a therapeutic modality to improve physical fitness and health-related quality of life. However, questions remain regarding its optimal effective and safe dose and its effects on the patients’ cardiac function. The study aimed to provide a wearable activity tracker (WAT)-based ET to promote physical activity in CF patients and assess its effects on cardiac morphology and function. Forty-two stable CF individuals (aged 16.8 ± 3.6 years) were randomly assigned to either the intervention (Group A) or the control group (Group B). Group A participated in a 1-year WAT-based ET program three times per week. All patients underwent a 6-min walking test (6-MWT) and an echocardiographic assessment focused mainly on RV anatomy and function at the baseline and the end of the study. RV systolic function was evaluated by measuring the tricuspid annular plane systolic excursion (TAPSE), the systolic tricuspid annular velocity (TVS’), the RV free-wall longitudinal strain (RVFWSL), and the right ventricular four-chamber longitudinal strain (RV4CSL). RV diastolic function was assessed using early (TVE) and late (TVA) diastolic transtricuspid flow velocity and their ratio TVE/A. Pulmonary artery systolic pressure (PASP) was also estimated. In Group A after ET, the 6MWT distance improved by 20.6% (p < 0.05), TVA decreased by 17% (p < 0.05), and TVE/A increased by 13.2% (p < 0.05). Moreover, TAPSE, TVS’, RVFWSL, and RV4CSL increased by 8.3% (p < 0.05), 9.0% (p < 0.05), 13.7% (p < 0.05), and 26.7% (p < 0.05), respectively, while PASP decreased by 7.6% (p < 0.05). At the end of the study, there was a significant linear correlation between the number of steps and the PASP (r = −0.727, p < 0.01) as well as the indices of RV systolic function in Group A. In conclusion, WAT is a valuable tool for implementing an effective ET program in CF. Furthermore, ET has a positive effect on RV systolic and diastolic function.

Abstract
BACKGROUND AND AIMS
The effects of exercise training in kidney transplant (KT) recipients with diabetes mellitus remain unclear [1]. This randomized controlled trial aimed to investigate the effects of a 6-month home-based exercise training programme on functional capacity, glucose levels and lipid profile of diabetic KT patients.
METHOD
A total of 21 type II diabetic KT recipients were randomly assigned into two groups: exercise (n = 11, aged 52.9 + 10.1 years) and control (n = 10, aged 53.01 + 9.5 years). All participants at baseline and at the end of the study underwent biochemical tests for fasting plasma glucose (FPG) levels, glycated haemoglobin (HbA1c) and lipid profile and cardiopulmonary exercise testing for maximum oxygen uptake (VO2peak) estimation. The exercise group followed a 6-month supervised home-based aerobic and progressive resistance exercise programme of moderate intensity, 3 times/week, while the control group continued to receive usual care.
RESULTS
At the end of the 6-month study, the exercise group had significantly lower values in FBG by 13.4% (P = .01), HbA1c by 1.5% (P = .01) and triglycerides by 8.5% (P < .05) and higher values in high-density lipoprotein by 10.2% (P < .05) and VO2peak by 4.7% (P = .02) than the control group. Moreover, there were statistically significant differences between the two groups at the end of the study for FBG, triglycerides and VO2peak. Finally, after training there was a moderate, positive linear relationship between VO2peak and HbA1c in the exercise group (r = 0.408, P = .03).
CONCLUSION
The results of this study demonstrated that a 6-month home-based mixed-type exercise training programme can improve the functional capacity, levels of glucose and lipid profile of diabetic KT recipients.

Abstract
The use of substances and medications with potential cardiovascular effects among those practicing sports and physical activity has progressively increased in recent years. This is also connected to the promotion of physical activity and exercise as core aspects of a healthy lifestyle, which has led also to an increase in sport participation across all ages. In this context, three main users' categories can be identified, (i) professional and amateur athletes using substances to enhance their performance, (ii) people with chronic conditions, which include physical activity and sport in their therapeutic plan, in association with prescribed medications, and (iii) athletes and young individuals using supplements or ergogenic aids to integrate their diet or obtaining a cognitive enhancement effect. All the substances used for these purposes have been reported to have side effects, among whom the cardiovascular consequences are the most dangerous and could lead to cardiac events. The cardiovascular effect depends on the type of substance, the amount, the duration of use, and the individual response to the substances, considering the great variability in responses. This Position Paper reviews the recent literature and represents an update to the previously published Position Paper published in 2006. The objective is to inform physicians, athletes, coaches, and those participating in sport for a health enhancement purpose, about the adverse cardiovascular effects of doping substances, commonly prescribed medications and ergogenic aids, when associated with sport and exercise.

Abstract
Hereditary diseases under the age of 35 are the most common underlying heart disease, leading to sudden cardiac death (SCD) in competitive sports, while in older people, atherosclerotic coronary artery disease (CAD) is the main cause. The following preventive measures are recommended: (a) The pre-participation cardiovascular screening, (b) the genetic testing, (c) the use of implantable cardioverter-defibrillator (ICD), (d) the prohibition of doping in sports, (e) the prevention of 'exercise-induced' cardiac complications, (f) the reduction of high-risk factors for CAD, and (g) the use of cardiopulmonary resuscitation. The cost-effectiveness of the electrocardiograms in the pre-participation screening programs remains questionable. Genetic testing is recommended in borderline cases and positive family history. Athletes with ICD can, under certain conditions, participate in competitive sports. Excessive endurance exercise appears to harm the endothelium, promotes inflammatory processes and leads to fibrosis in the myocardium, and calcium deposition in the coronary vessels. Cardiac arrest may be reversed if cardiopulmonary resuscitation is performed and a defibrillator is immediately used. Thus, equipping all fields with automatic external defibrillators are recommended.

Background/Introduction: Long-time endurance exercise training leads to cardiovascular, respiratory, haematological and neuromuscular adaptations. The relative contribution of these adaptations to running performance in long-distance races remains to be elucidated in an integrative manner.
Purpose
The study of the relationship of marathon performance with anthropometric, cardiorespiratory and haematological adaptations.
Methods
Thirty-one marathon runners (26 males, age: 42 ± 9 years) were examined within 3 weeks before Athens marathon race (42.195 km). Assessment of training characteristics, anthropometric measurements, including height, body weight and body fat percentage, echocardiographic study, cardiopulmonary exercise testing using treadmill ergometer and blood test were performed.
Results
Training age was 11(1-39) years. Body fat percentage(BFP) was 17.3 ± 7.1% and body weight-indexed maximum oxygen uptake(VO2max) was 52.6 ± 8.9 mL/kg/min. Marathon race time(MRT) was 3:59:01(2:47:17-5:31:32). Among anthropometric measurements, MRT was positively associated with BFP(r= 0.561, p = 0.002) and body fat mass(r = 0.514, p = 0.005), even after adjustment for VO2max or oxygen uptake at first(VO2-VT1) or second(VO2-VT2) ventilatory threshold, implying an effect of BFP on running economy. Among echocardiographic parameters, MRT correlated negatively with right ventricular end-diastolic area(RVEDA) (r = -0.707, p < 0.001) and ratio of early to late diastolic transtricuspid flow velocity(TVE/A) (r= -0.430, p = 0.025). MRT correlated negatively with body weight-indexed VO2max (r= -0.692, p < 0.001), VO2-VT1 (r= -0.426, p = 0.019) and VO2-VT2 (r= -0.688, p < 0.001). MRT correlated negatively with maximum minute ventilation(VEmax) (r= -0.418, p = 0.022), VEmax indexed for body surface area(BSA) (r= -0.456, p= 0.011), maximum tidal volume(Vtmax) indexed for BSA(r= -0.436, p = 0.018) and oxygen uptake efficiency slope(OUES) (r= -0.529, p = 0.003). MRT was not associated with haemoglobin concentration. RVEDA correlated positively with maximum oxygen pulse (r = 0.653, p = 0.001), which is an estimate of stroke volume during exercise, and OUES(r = 0.534, p = 0.009). After performing multivariate linear regression analysis with MRT as dependent variable and BFP(standardized β=0.495, p = 0.001), RVEDA(standardized β= -0.550, p = 0.001) and Vtmax indexed for BSA(standardized β= -0.110, p = 0.418) as independent variables, only BFP and RVEDA were significant independent predictors of MRT(adjusted R2 = 0.667, p < 0.001 for the model).
Conclusions
The results of the present study demonstrated that the main cardiorespiratory adaptation that could predict a better marathon performance was right ventricular dilatation, through the increase in stroke volume during exercise, whereas upregulation of tidal volume during exercise was found to be a weaker predictor. The principal anthropometric determinant of marathon performance appears to be body fat percentage, via the influence on running economy.

Abstract
There is little research about the effects of ultra-endurance exercise on arterial morphological and functional properties. The aim was to assess the acute changes of the carotid-femoral pulse wave velocity and carotid doppler-derived parameters following an ultra-marathon race as well as the intima-media thickness of the carotid artery in ultra-marathon runners. Twenty athletes were examined at baseline and within 10 mins after a 246 km running race. Measurements included carotid-femoral pulse wave velocity, peak-systolic and end-diastolic velocities of carotid artery blood flow, pulsatility and resistivity indices and blood biochemical parameters. The intima-media thickness of the right and left carotid artery was measured before the race. Arterial stiffness and carotid artery intima media thickness at rest remained within known normal limits. The ultra-marathon race significantly increased carotid-femoral pulse wave velocity by 22.6% and pulsatility index by 10.2%. There was a decrease in body weight by 3.35% and an increase of all biochemical markers of muscle damage after the race. Additionally, C-reactive protein was correlated with both pulsatility and resistivity indices post-race. This study shows that immediately after a 246 km ultra-marathon running race, acute increase of arterial stiffness and vascular resistance were evident. The carotid artery thickness of ultra-marathon runners was within normal range.

Abstract
Dialysis patients show a high rate of reduced functional capacity, morbidity and mortality. Cardiovascular disorders, muscle atrophy and malnutrition play an essential role among the aetiological factors. Sedentary lifestyle characterizes them and contributes to the aggravation of the disorders. On the contrary, exercise training is an important preventive and therapeutic tool both for cardiovascular problems and for the appearance of muscle atrophy in dialysis patients. Regular exercise causes both central (cardiac) and peripheral (muscular) adaptations, improving functional capacity. In particular, circulatory system clinical trials in haemodialysis (HD) patients documented that exercise has favourable effects on heart function, promotes balance on the cardiac autonomic nervous system and contributes to the management of arterial hypertension. In the muscular system, it prevents muscle atrophy or contributes significantly to its treatment. The main preventive mechanisms of the beneficial effect of exercise on the muscles constitute the inhibition of the apoptotic processes and protein degradation. Exercise training in HD patients leads to an increase of muscle fibers, mitochondria and capillaries, and the combination of regular exercise and dietary strategies is even more effective in preventing or treating muscle atrophy. Finally, an improvement in functional capacity and quality of life was found also in peritoneal dialysis patients following exercise training.

Abstract
Abstract
Background
It is well documented that prolonged intense exercise such as a marathon, transitorily alters cardiac function. However, the impact of ultra-endurance (UE) exercise on global and segmental longitudinal deformation of all cardiac chambers and on inter-chamber functional relationships has not yet been thoroughly investigated.
Purpose
The aim of the study was the evaluation of the acute effects of UE exercise on longitudinal deformation of all cardiac chambers and on intra-, inter- and atrioventricular functional relationships.
Methods
Echocardiographic assessment was performed the day before and at the finish line of “Spartathlon”: a 246 Km ultra-marathon. 2D speckle-tracking echocardiography was performed in all 4 chambers during the same cardiac cycle, allowing a simultaneous strain-time data display of all cardiac chambers (Figure 1). Peak global deformation values and temporal parameters adjusted for the heart rate were extracted from the derived curves, while a segmental analysis for left (LV) and right ventricle (RV) was also performed.
Results
Out of 60 participants initially screened, 27 athletes (17 male, age 45±7 years) finished the race in 33:34±1:59 hours. Both LV (−20.9±2.3 pre- to −18.8±2% post-, p=0.009) and RV global strains (−22.9±3.6 pre- to −21.2±3% post-, p=0.04) decreased post-race, even though remained within normal range for the 85% of the participants. Peak atrial strains [right (RA) and left (LA)] did not change (p=0.12 and 0.95). Basal and mid segmental strain values significantly decreased post-race, while both LV and RV apical strain values remained unaffected (p=0.899 and p=0.46, accordingly) (Figure). Concerning interchamber relationships, RV and RA strain curves were constantly larger in magnitude than those of the LV and LA, with RV/LV, LV/LA, RV/RA and RA/LA peak values' ratios remaining unchanged from pre- to post-race. Finally, although right chambers' time-to-peak values were shorter compared to the left ones, all chambers' strain curves peaked later post-race (p<0.001 for all).
Conclusions
Despite subtle changes in LV and RV strain, 4-chamber deformation values remained within normal range even after running a 246 km ultra-marathon. Following a segmental analysis, this finding could be explained for both ventricles by a preservation of apical deformation. Additionally, inter- and atrioventricular concordance was also maintained.

Abstract
PURPOSE Patients with end-stage renal disease (ESRD) seem to have a negative attitude towards physical activity, which is mainly favored by the lack of counseling provided by the medical and nursing staff. The aim of this study was to investigate the attitudes of both ESRD patients and medical staff on the participation and promotion of physical activity and identify the obstacles that discourage patients' involvement in intervention programs. STUDY DESIGN Subjective assessment questionnaires and the International Physical Activity Questionnaire were administrated to hemodialysis patients and medical staff, to investigate the association between patient's barriers to physical activity, the total intensity level of physical activity, and attitudes of both ESRD patients and medical staff on the participation and promotion of physical activity. RESULTS A total of 103 ESRD patients (61 men, 59.2%), 20 nephrologists (12 men, 60.0%), and 72 nurses (61 women, 84.7%) participated in the study. Most commonly reported patient's barriers were fatigue on dialysis (97.4%) and non-dialysis days (55.1%). Healthcare staff showed positive attitude towards renal rehabilitation exercise programs. However, most of physicians (85.0%) and nurses (83.3%) did not have previous experience with interventional exercise rehabilitation programs. Binary logistic regression revealed significant association between patients' inactivity, demographic data, and barriers towards physical activity, such as fatigue and pain in dialysis and non-dialysis days (p < 0.05), family's and physician's concern (p < 0.05), too many medical problems (p < 0.05), the fear of getting hurt (p = 0.01), and unwillingness for exercise (p < 0.05). Interestingly, healthcare staff's negative attitudes toward patient's physical activity seem to be strongly associated with patient's inactivity status. CONCLUSION Healthcare staff negative attitudes and multiple related barriers especially fatigue on dialysis and non-dialysis days, towards ESRD patient's physical activity, suppress desire for exercise and active patients' status, leading them to abstain from it.

Abstract
BACKGROUND Although cardiopulmonary exercise (CPX) test is an essential tool for the assessment of functional capacity in athletes, limited information exists regarding the cardiorespiratory efficiency in young elite volleyball players. The main objective of the present study was to determine the maximal oxygen uptake (VO2max) and ventilatory anaerobic threshold (VT) during the CPX test in young male and female volleyball players. Moreover, to describe the behavior of the novel cardiorespiratory optimal point (COP) index and to assess its association with VO2max and VT. METHODS Eleven adolescent male (15.18 ± 0.75 years old) and 13 female (14.77 ± 0.44 years old) volleyball players underwent a graded maximal exercise test on a treadmill until exhaustion in order to obtain VO2max, VT and COP. The COP was set as the lowest ventilation (VE)/VO2 ratio at a given minute of spiroergometry. RESULTS COP values did not differ significantly between the two sexes (19.81 ± 1.29 and 20.44 ± 2.63 in males and females, respectively) and it was achieved at a speed of 3.41 ± 0.89 km/hr in males, and 3.78 ± 0.76 km/hr in females, lower than that achieved at the VT. COP was not correlated with VO2max (56.32 ± 6.36 ml/kg/min and 44.78 ± 3.65 ml/kg/min) nor with VT (34.81 ± 10.13 ml/kg/min and 34.13 ± 5.87 ml/kg/min) in male and female young volleyball players, respectively. CONCLUSIONS The novel submaximal cardiorespiratory index of COP does not seem to be associated with the traditional aerobic capacity indices in athletes such as VO2max and VT. Thus, it probably constitutes a separate parameter that needs to be further evaluated regarding its significance both in clinical evaluation and sports performance assessment of athletes.

Abstract
BACKGROUND Structural and functional arterial adaptations with regard to the type and level of training in young athletes are understudied. Our research aimed at evaluating them in two types of exercise (dynamic and static) and two levels of engagement (high and recreational). METHODS A total of 76 volunteers formed five groups. Group A included 17 high-level dynamic sports athletes 30·9 ± 6·4 years old, group B 14 recreational ones aged 28·7 ± 6·2 years, group C 15 high-level static sports athletes 26·4 ± 3·9 years old and group D 16 recreational ones, aged 25·8 ± 4·8 years. Fourteen sedentary men 30 ± 3·8 years old formed control group E. Structural indices of left cardiac chambers and thoracic aorta were echographically obtained, as well as common carotid intima-media thickness (cIMT). Furthermore, applanation tonometry was conducted, at rest and during a handgrip strength test, for the acquisition of central arterial pressure parameters, carotid-femoral pulse wave velocity (cfPWV) and total arterial compliance (Cτ ). RESULTS No significant differences in structural arterial markers were observed. However, group A obtained the highest handgrip central systolic pressure values (13·1% compared to group D, P<0·05). Resting cfPWV was lower in group B by 13·8% (P<0·05) than C and by 16·7% (P<0·01) than E, whereas Cτ was higher in group Β by 33·3% than C (P<0·05) and by 40·9% than E (P<0·01). CONCLUSION Functional arterial exercise-induced adaptations become apparent at an early age, without being in conjunction with structural ones. Recreational dynamic exercise results in the most favourable arterial characteristics.

Abstract
AIM Cardiac and vascular autonomic neuropathy contributes to increased morbidity and mortality in patients with chronic kidney disease. The aim of this study was to analyze the effects of a decline in glomerular filtration rate (GFR) on heart rate variability (HRV) and nocturnal blood pressure dipping. METHODS This cross-sectional study comprises 124 patients (46 women, 78 men; age 66 ± 14 years) with chronic kidney disease (CKD) 3-5, not on renal replacement therapy. GFR was measured with iohexol clearance, HRV with 24 h Holter electrocardiogram (ECG) and nocturnal dipping with 24 hour ambulatory blood pressure. RESULTS The GFR was 22.5 ± 8.5 mL/min per 1.73 m2 . The main finding was a significant curvilinear association between the 24 h standard deviation of NN interval (24SDNN) in the HRV analysis and GFR (P = 0.01), logGFR (P = 0.006), diabetes mellitus (P = 0.05) and beta blocker treatment (0.03), respectively. The effect of diabetes mellitus on 24SDNN corresponded to a decline in GFR from 30 to 12 mL/min per 1.73 m2 . There were significant curvilinear associations between systolic nocturnal dipping (P = 0.02) and diastolic nocturnal dipping (P = 0.05), respectively, and diabetes mellitus but not with GFR or logGFR. CONCLUSION In conclusion, cardiac sympathetic overdrive and decreased vagal control appear during CKD 4 and 5. The association with GFR is curvilinear. Diabetes mellitus was significantly associated with both cardiac and vascular autonomic neuropathy, as measured by heart rate variability and nocturnal blood pressure dipping, respectively. Knowing that arrhythmias, often due to sympathetic hyperactivity, are an important cause of sudden death in the dialysis population, this study contributes important knowledge on possible intervention thresholds.

Abstract
Current public health recommendations include adequate diet and exercise in order to reduce the risk of chronic disease, especially vascular disease and other complications associated with obesity. The purpose of this study was to investigate possible relationships between the level of habitual physical activity, eating patterns, and diet composition in apparently healthy adults who exercise regularly. Subjects completed questionnaires and diaries regarding their fitness activity and nutrition. Time spent in the lowest energy expenditure category was associated with high cholesterol intakes and time spent in activities comparable to walking at a leisurely pace and light housework was associated with lower fat consumption. Fat consumption was also higher and carbohydrate consumption was lower than optimal. There was no other correlation between physical activity and the intake of any other nutrient. Further investigation is needed in sedentary populations in order to compare these findings.

Abstract
The authors examined cardiovascular responses to long-distance fin swimming as compared to freestyle swimming. Elite male fin swimmers (n=17) swam 8 km in the open sea (group A) and 17 top freestyle endurance swimmers (group B) swam 6 km in the open sea. The swimming times of the 2 groups did not differ significantly. The heart rate and mean blood pressure were higher in group B than in group A after exercise. As estimated from the systolic time intervals (STI), total electromechanical systole index (QS2I) and electrical systole index (QTI) increased and QT-QS2 decreased in both types of swimming. These changes were more marked in fin swimmers. Moreover, the preejection period (PEPI) and the preejection period to left ventricular ejection time ratio (PEP/LVET) significantly decreased in both groups, while LVET remained constant in the 2 swimming events. Likewise, the amount of change in PEP/LVET was more pronounced in group A. Finally, only the QT-QS2 changes were associated with performance efforts in both groups. Therefore, there are quantitative cardiovascular differences between these types of swimming that should be primarily attributed to the different muscle mass effort involved.

Abstract
The use of doping substances and methods is extensive not only among elite athletes, but also among amateur and recreational athletes. Many types of drugs are used by athletes to enhance performance, to reduce anxiety, to increase muscle mass, to reduce weight or to mask the use of other drugs during testing. However, the abuse of doping substances and methods has been associated with the occurrence of numerous health side-effects. The adverse effects depend on the type of the consumed drug, as well as the amount and duration of intake and the sensitivity of the body, since there is a large inter-individual variability in responses to a drug. Usually the doses used in sports are much higher than those used for therapeutic purposes and the use of several drugs in combination is frequent, leading to higher risk of side-effects. Among biomedical side-effects of doping, the cardiovascular ones are the most deleterious. Myocardial infarction, hyperlipidemia, hypertension, thrombosis, arrythmogenesis, heart failure and sudden cardiac death have been noted following drug abuse. This paper reviews the literature on the adverse cardiovascular effects after abuse of prohibited substances and methods in athletes, aiming to inform physicians, trainers and athletes and to discourage individuals from using drugs during sports.

Abstract
AIMS The objective of this study was to evaluate the effect of a training programme based on traditional Greek dance on the jumping ability, muscle strength and lower limb endurance in patients with chronic heart failure (CHF). PATIENTS AND METHODS Forty Greek patients with CHF graded as NYHA ⩽ II and aged 73.2±4.7 years were randomly divided into two groups. Group A ( n=20) participated in a three-month physical rehabilitation programme based on Greek traditional dances, whereas group B ( n=20) remained untrained and served as the control group. All patients were studied before and after the 12-week exercise training programme. At baseline and follow-up the exercise capacity of the patients was evaluated by the six-minute walking test, their lower extremity muscle strength was evaluated by an isokinetic dynamometer and their jumping ability by the Myotest-Pro test, which includes three types of jumps (plyometric, countermovement and squat jumps). RESULTS No significant difference was observed between the two groups at the baseline evaluation. At follow-up, group A showed significant improvements in walking distance calculated from the six-minute walking test (10.0% improvement; p<0.05), in lower limb strength (10.32% improvement; p<0.05), and in countermovement jump speed (6.9%; p<0.05) and squat jump speed (5.8%; p<0.05). Group A also increased their jump plyometry height by 13.86% ( p<0.05), their counter jump height by 10.68% ( p<0.05) and their squat jump height by 10.45% ( p<0.05). Group A had a 6.85% ( p<0.05) increased force of counter jump compared with group B. CONCLUSION The design and implementation of cardiac rehabilitation programmes using Greek traditional dances in patients with CHF are both safe and effective in improving lower limb function.

Abstract
Objective: To address whether transtelephonic electrocardiographic monitoring (TEM) of patients with chronic cardiac diseases, being exercised in public gyms, is safe and efficacious. Design: Data were obtained from 91 patients (72 men and 19 women; with a mean (SD) age of 56 (6) years and over a total of 11 820 exercise hours) with coronary heart disease and/or chronic heart failure (≤ stage III NYHA (New York Heart Association)), who were referred for cardiac exercise rehabilitation (phase III). Method: Twelve-lead electrocardiograms of indicated patients were transmitted from the qualified trainers in real time by standard telephone lines and were evaluated by the medical staff at the base. The TEM kits contain a telemedicine 12-lead electrocardiographic unit, a telephone modem, a computer receiver with special operating software and a laser printer. As soon as the ECG was monitored and diagnosed, the cardiologist contacted the exercise trainer and provided all the necessary instructions for intervention. Results: In total, 280 cases were monitored. Successful TEM was reported in 99.3% of the cases. The mean (SD) time from ECG recordings to final interventions was estimated at 294 (13) s. The patients were referred for TEM during or soon after exercise sessions, because of chest pain (36% of the TEM cases), palpitations (33%), dizziness (12%), unexpected fatigue (9%), hypertensive crises (7%) and other disorders (3%). Ischaemic ECG changes were recorded in 14 cases with thoracic pain and arrhythmias in nine patients with palpitations. In only one case was a medical emergency reported and an ambulance response required. Conclusion: These data demonstrate that TEM provides a workable facility in cardiac rehabilitation for monitoring patients who are exercising in gyms.

Abstract
Molasses wastewater is a high strength effluent of food industry such as distilleries, sugar and yeast production plants etc. It is characterized by a dark brown color and exhibits a high content in substances of recalcitrant nature such as melanoidins. In this study, electrocoagulation (EC) was studied as a post treatment step for biologically treated molasses wastewater with high nitrogen content obtained from a baker's yeast industry. Iron and copper electrodes were used in various forms; the influence and interaction of current density, molasses wastewater dilution, and reaction time, on COD, color, ammonium and nitrate removal rates and operating cost were studied and optimized through Box Behnken's response surface analysis. Reaction time varied from 0.5 to 4 h, current density varied from 5 to 40 mA/cm(2) and dilution from 0 to 90% (v/v expressed as water concentration). pH, conductivity and temperature measurements were also carried out during each experiment. From preliminary experiments, it was concluded that the application of aeration and sample dilution, considerably influenced the kinetics of the process. The obtained results showed that COD removal varied between 10 and 54%, corresponding to an operation cost ranging from 0.2 to 33 euro/kg COD removed. Significant removal rates were obtained for nitrogen as nitrate and ammonium (i.e. 70% ammonium removal). A linear relation of COD and ammonium to the design parameters was observed, while operation cost and nitrate removal responded in a curvilinear function. A low ratio of electrode surface to treated volume was used, associated to a low investment cost; in addition, iron wastes could be utilized as low cost electrodes i.e. iron fillings from lathes, aiming to a low operation cost due to electrodes replacement. In general, electrocoagulation proved to be an effective and low cost process for biologically treated molasses-wastewater treatment for additional removal of COD and nitrogen content and color reduction. Treated effluent samples with good quality were produced by EC, with COD, NH4-N and NO3-N concentrations of 180, 52 and 2 mg/l respectively. Response surface analysis revealed that optimized conditions could be established under moderate molasses wastewater dilution, (e.g. 45%), at 3.5 h treatment time and 33 mA/cm(2) current density.

Abstract
The aim of this study is to evaluate the cost-effectiveness of ECG in combination with family and personal history and physical examination in order to detect cardiovascular diseases that might cause sudden death in athletes. The study was conducted on a cohort of 6,634, mainly young professional and recreational athletes, 1,071 from Algeria and 5,563 from Europe (France, Germany and Greece). Each athlete underwent medical history, physical examination, and resting 12-lead ECG. 293 athletes (4.4 %), 149 in Europe (2.7 %) and 144 in Algeria (13.4 %) required further tests, and 56 were diagnosed with cardiovascular disease and thus disqualified. The cost-effectiveness ratio (CER) was calculated as the ratio between the cost of screening and the number of statistical life-years saved by the intervention. The estimated reduced risk of death deriving from treatment or disqualification resulted in the saving of 79.1 statistical life-years in Europe and 136.3 in Algeria. CER of screening was 4,071 purchasing-power-parity-adjusted US dollars ($PPP) in Europe and 582 $PPP in Algeria. The results of this study strongly support the utilisation of 12-lead ECG in the pre-participation screening of young athletes, especially in countries where secondary preventive care is not highly developed.

DESIGN Randomized controlled trial. SETTING Sports Medicine Laboratory. SUBJECTS A total of 31 patients, aged 59.9 ± 14.1 years. INTERVENTIONS They were randomly assigned either to a Greek traditional dancing programme (Group A) or to a sedentary control group (Group B). MAIN MEASURES A functional capacity assessment was performed at baseline and the end of the study. Global Assessment of Functioning Scale and Positive and Negative Syndrome Scale were also used. Quality of life was examined using the Quality of Life and Satisfaction questionnaire. RESULTS After the eight months, Group A increased walking distance in the 6-minute walk test (328.4 ± 35.9 vs. 238.0 ± 47.6 m), sit-to-stand test (19.1 ± 1.8 vs. 25.1 ± 1.4 seconds), Berg Balance Scale score (53.1 ± 2.1 vs. 43.2 ± 6.7), lower limbs maximal isometric force (77.7 ± 25.7 vs. 51.0 ± 29.8 lb), Positive and Negative Syndrome Scale total score (77.0 ± 23.1 vs. 82.0 ± 24.4), Global Assessment of Functioning Scale total score (51.3 ± 15.5 vs. 47.7 ± 13.3) and Quality of Life total score (34.9 ± 5.2 vs. 28 ± 4.5), compared with Group B. CONCLUSIONS Our results demonstrate that Greek traditional dances improve functional capacity and quality of life in patients with schizophrenia.

Abstract
Most of the available data on the cardiovascular screening of athletes come from Italy, with fewer records being available outside of Italy and for non-Caucasian populations. The goals of the SMILE project (Sport Medicine Intervention to save Lives through ECG) are to evaluate the usefulness of 12-lead ECGs for the detection of cardiac diseases in athletes from three European countries and one African country and to estimate how many second-level examinations are needed subsequent to the initial screening in order to classify athletes with abnormal characteristics. A digital network consisting of Sport Centres and second and third opinion centres was set up in Greece, Germany, France and Algeria. Standard digital data input was carried out through the application of 12-lead ECGs, Bethesda questionnaires and physical examinations. Two hundred ninety-three of the 6,634 consecutive athletes required further evaluation, mostly (88.4 %) as a consequence of abnormal ECGs. After careful evaluation, 237 were determined to be healthy or apparently healthy, while 56 athletes were found to have cardiac disorders and were thus disqualified from active participation in sports. There was a large difference in the prevalence of diseases detected in Europe as compared with Algeria (0.23 and 4.01 %, respectively). Our data confirmed the noteworthy value of 12-lead resting ECGs as compared with other first-level evaluations, especially in athletes with asymptomatic cardiac diseases. Its value seems to have been even higher in Algeria than in the European countries. The establishment of a digital network of Sport Centres for second/third opinions in conjunction with the use of standard digital data input seems to be a valuable means for increasing the effectiveness of screening.

Abstract
BACKGROUND There are conflicting data regarding the effects of renal transplantation (RT) on uraemic autonomic dysfunction. Moreover, no study has examined the impact of physical training on the cardiac autonomic function in RT patients. Thus, we studied the effects of exercise training on heart rate variability (HRV) and arterial baroreflex sensitivity (BRS), which are sensitive markers of cardiac autonomic outflow, in RT recipients. METHODS Eleven patients (Exercise group-aged 52.1 ± 5.6 years) were studied before and after 6 months of exercise training. Twelve age- and sex- matched RT patients (Sedentary) and 12 healthy sedentary individuals (Healthy), who remained untrained, served as controls. At baseline and follow-up, all the subjects underwent cardiopulmonary exercise testing for the evaluation of peak oxygen consumption (VO2peak), a tilt test for the evaluation of BRS and baroreflex effectiveness index (BEI) and an ambulatory 24-h Holter monitoring for time- and frequency-domain measures of HRV. RESULTS In the exercise group, VO2peak increased by 15.8% (P < 0.05) and all depressed HRV and BRS indices were significantly improved after training. Specifically, the standard deviation of all normal-to-normal (NN) intervals (SDNN) significantly increased by 92.5%, the root-mean-square of the differences between consecutive NN intervals by 45.4%, the percentage value of NN50 count by 58.2%, the high-frequency by 74.8% and low-frequency spectral power by 41.6%, BRS by 43.7% and BEI by 57.3%. None of the variables studied was altered over time in either control group. CONCLUSIONS The increased cardiorespiratory fitness by exercise training was associated with an improved BRS function and a modification of the sympathovagal control of HRV towards a persistent increase in parasympathetic tone. These alterations may lead to a better cardiovascular prognosis in RT recipients.

Abstract
BACKGROUND The assessment of functioning and disability is an important part of the clinical evaluation, since it measures disease burden and reflects the effectiveness of therapeutic planning and interventions. The aim of the current study was to develop such a self-report instrument on the basis of a review of the literature, and compatible with the WHO approach. MATERIAL AND METHODS The review of the literature led to the development of the Global Disability Scale (Glo.Di.S) with 25 items assessing different aspects of disability. The study sample included 728 persons from vulnerable populations (homeless, jobless, very low income, single parent families etc.; (29.12% males and 70.88% females; aged 55.96 ± 15.22 years). The protocol included also the STAI and the CES-D. The statistical analysis included factor analysis item analysis and ANCOVA. RESULTS The factor analysis revealed the presence of 4 factors explaining 71% of total variance (Everyday functioning, Social and interpersonal functioning, Severity and Mental disability). Chronbach's alpha for the whole scale was 0.95 and for subscales were 0.74-0.94. DISCUSSION The results of the current study suggest that the Glo.Di.S. has the potential to serve as a reliable and valid tool for assessing functioning and disability. Further research is needed to prove that it could be useful across countries, populations and diseases, and whether it provides data that are culturally meaningful and comparable. It can be used in surveys and in clinical research settings and it can generate information of use in evaluating health needs and the effectiveness of interventions to reduce disability and improve health.

Abstract
The aim of the study was to evaluate the cardiac autonomic activity in free diving (FD) athletes. Thirteen Greek male free divers (group I, aged 33.4 ± 6.3 years, 6.6 ± 4.5 years of training experience) volunteered to participate while 13 age-matched sedentary subjects served as control group (group II). All subjects were submitted to ambulatory 24-h ECG recording for heart rate variability (HRV) analysis on a day of regular activities with no exercise or training. The results showed that group I had significantly lower minimum and mean heart rate by 23.9% (P < 0.001) and 20.6% (P < 0.001), respectively. All the measured time and frequency domain indices of HRV which reflect cardiac parasympathetic activity were higher in group I than in group II by 37.6% to 146% (P < 0.001). Conclusively, the resting cardiac autonomic activity and especially the parasympathetic branch was significantly increased in free divers compared to untrained subjects. This finding should be rather attributed to the accumulated effect of both exercise training and frequent exposure to FD stimulus.

Abstract
Objective: To investigate whether a structured long-term exercise training programme in patients with coronary artery disease affects baroreflex function and cardiorespiratory efficiency. Patients: Twenty-five elderly male patients with coronary artery disease. Methods: The patients were randomized into exercise (group A) or control group (group B). Group A followed a seven-month supervised exercise programme, consisting of three sessions of aerobic interval training weekly at moderate intensity. Twenty patients completed the study (group A: 10 patients and group B: 10 patients). At the beginning and end of the study, all subjects underwent a tilt test for the baroreflex sensitivity assessment and a graded exercise treadmill test with spiroergometry for the evaluation of their cardiorespiratory efficiency. Results: There were no differences between the two groups for any baseline variable. After training in group A, peak oxygen consumption, maximal treadmill tolerance time and anaerobic threshold were significantly increased by 21.9% ( P < 0.001), 19.8% ( P < 0.001) and 18.6% ( P < 0.05), respectively. There were also significant increases in baroreflex sensitivity by 21.2% ( P < 0.01), in baroreflex effectiveness index by 23.9% ( P < 0.01), in event count by 45.1% ( P < 0.01) and in ramp count by 13.2% ( P < 0.05). Moreover, significant correlations were observed between the autonomic and cardiorespiratory parameters in group A at the end. Conclusion: The results suggest that long-term exercise training leads to beneficial effects on baroreflex activity and cardiorespiratory performance in coronary patients, and thus could constitute an efficient nonpharmacological intervention in this population.

Abstract
Cardiovascular remodelling in the conditioned athlete is frequently associated with physiological ECG changes. Abnormalities, however, may be detected which represent expression of an underlying heart disease that puts the athlete at risk of arrhythmic cardiac arrest during sports. It is mandatory that ECG changes resulting from intensive physical training are distinguished from abnormalities which reflect a potential cardiac pathology. The present article represents the consensus statement of an international panel of cardiologists and sports medical physicians with expertise in the fields of electrocardiography, imaging, inherited cardiovascular disease, cardiovascular pathology, and management of young competitive athletes. The document provides cardiologists and sports medical physicians with a modern approach to correct interpretation of 12-lead ECG in the athlete and emerging understanding of incomplete penetrance of inherited cardiovascular disease. When the ECG of an athlete is examined, the main objective is to distinguish between physiological patterns that should cause no alarm and those that require action and/or additional testing to exclude (or confirm) the suspicion of an underlying cardiovascular condition carrying the risk of sudden death during sports. The aim of the present position paper is to provide a framework for this distinction. For every ECG abnormality, the document focuses on the ensuing clinical work-up required for differential diagnosis and clinical assessment. When appropriate the referral options for risk stratification and cardiovascular management of the athlete are briefly addressed.

Abstract
OBJECTIVE The aim of this study was to evaluate the changes in the levels of vasoactive eicosanoid hormone-like substances PGE2, PGI2 and TXA2 in hemodialysis (HD)patients who were following a long-term physical training program during the hemodialysis session. DESIGN A total of 50 patients with Chronic Kidney Disease (CKD) (stage 5)on hemodialysis and 35 healthy individuals who served as controls (C) were evaluated. The 50 CKD patients were divided into two groups: the HD group consisted of 31 patients who received usual care without any physical activity during the hemodialysis sessions, while group HD/Exer included 19 patients who followed a program of physical exercise for six months. Plasma levels of PGE2, 6-Keto-PGF1alpha (the stable derivative of PGI2) and TXB2 (the stable derivative of TXA2) were measured by reliable enzymo-immunoassay methods (EIA) in HD and HD/Exer patients before and after the hemodialysis sessions as well as in the group of C. RESULTS The plasma levels of PGE2 and 6-keto-PGF1alpha in group HD Exer/before patients were higher than those in group HDbefore (20.39+/-5.82 and 1449.19+/-553.41 vs 17.68+/-5.36 and 1295.10+/-384.43 pg/ml, p=0.044 and p=0.067, respectively), while the plasma levels of TXB2 were lower in HD Exer/before patients compared to HDbefore(499.76+/-67.51 vs 608.01+/-80.23 pg/ml, p=0.041). The plasma levels of PGE2 and 6-keto-PGF1alpha in group HD Exer/after patients were significantly higher compared to those in HDafter patients (23.01+/-5.70 and 1618.19+/-435.07 vs 16.57+/-4.97 and 1005.44+/-317.16 pg/ml, p<0.001 and p<0.040, respectively). However, significantly lower values in the plasma levels of TXB2 in HD Exer/after compared to HDafter patients (363.10+/-51.91 vs 439.75+/-62.34 pg/ml, p=0.030) were detected. As expected, PGE2 and 6-keto-PGF1alpha values were lower in C than in the groups of patients with CKD. CONCLUSIONS The data indicate that exercise training during HD exerts a beneficial effect on the levels of the vasoactive eicosanoid hormone-like substances in patients on HD.

Abstract
OBJECTIVE To assess the effects of intradialytic exercise training on health-related quality of life indices in haemodialysis patients. SUBJECTS/PATIENTS Thirty-five patients on haemodialysis, with a mean (SD) age of 48.8 (13.9) years, volunteered to participate in the study. They were randomized either to rehabilitation group (group A: 19 patients), following a 10-month intradialytic exercise training programme or to control group (group B: 14 patients). After the randomization, two of the patients, one of each group, withdrew from the study for reasons unrelated to exercise training. METHOD All patients at the beginning and the end of the study underwent clinical examination, laboratory tests and a treadmill exercise testing with spiroergometric study for the evaluation of their aerobic capacity (Vo(2peak)). A formal psychosocial assessment, which included affective (Beck Depression Inventory), health-related quality of life (Quality of Life Index, Living Questionnaire of Minnesota, Life Satisfaction Index and Short Form-36 questionnaire) and personality (Eysenck Personality Questionnaire) parameters, was evaluated at beginning and end of the study. The dose of erythropoietin was changed as needed, according to the level of the haemoglobin, aiming to keep it at 11 (2) g/dL during the study. RESULTS Baseline values were similar between the two groups. After training in group A, Vo(2peak) was increased by 21.1% (P<0.05) and exercise time by 23.6% (P<0.05). Moreover, group A showed a decrease in self-reported depression (Beck Depression Index) of 39.4% (P<0.001). In addition, trained patients demonstrated a significant improvement in Quality of Life Index (from 6.5 (1.8) to 9.0 (1.3), P<0.001) and Life Satisfaction Index (from 44.8 (8.6) to 53.0 (5.6), P<0.001), and an increase in the Physical Component Scale of the SF-36 (from 40.5 (5.6) to 44.5 (5.5), P<0.05), while the Mental Component Scale remained unchanged. Multiple regression analysis indicated that the improvement in quality of life depended on the participation in exercise programmes, the effects of training and the reduction in the level of depression. No changes were observed in Eysenck Personality Questionnaire by the end of the study, while all the above parameters remained almost unchanged in the controls. CONCLUSION The results demonstrated that intradialytic exercise training improves both physical functioning and psychological status in haemodialysis patients, leading to an improvement of patients' quality of life.
