“…It is known that the aerobic fitness level is associated with low values of HRmax in healthy individuals, what has been related to high values of maximal cardiac output [29], high stroke volume and hypertrophy of the left ventricle [30]. This is in agreement with the findings of Fu et al [31], whom observed higher values of cardiac output after 12 weeks of aerobic training accompanied by an improvement in the OUES. Thereby, it is tempter to suggest that the oxygen uptake efficiency may be increased by similar mechanisms responsible to decrease HRmax such as cardiac output enhancement [29] and parasympathetic nervous system activity [32].…”

Objective: The purpose of this study was to investigate if the OUES is determined by the same factors when calculated with VO 2 and VE values throughout the incremental test (OUES 100 ) or using values until 80% of the VO 2 max (OUES 80 ).Methods: 116 healthy male individuals performed a maximal incremental test, two constant-speed tests and a maximal dynamic strength test.Results: OUES 100 and OUES 80 were significantly correlated (r = 0.964; P < 0.001). VO 2 max was the main determinant factor for both OUES 100 and OUES 80 . Additionally, maximal heart rate (HRmax) and maximal dynamic strength (1RM) were the other variables selected for the two models as secondary variables. However, the importances of them were inversed, with the HRmax being the second determinant of the OUES 80 , while 1RM the second determinant for OUES 100 . The running economy, ventilatory threshold and respiratory compensation point were not selected for the models (P > 0.05). Conclusions:Our results suggest that the OUES 80 might satisfactorily replace maximal variables in aerobic fitness evaluations without maximal effort requirement. VO 2 max seems to be the main factor determining oxygen uptake efficiency slope, regardless the range (maximal or submaximal) used to determine. Otherwise, the muscle strength plays a more important role to the oxygen uptake efficiency considering maximal intensities, while the cardiovascular system seems to more strongly influence the oxygen uptake efficiency only until submaximal intensities.

Exercise-based rehabilitation is considered an important adjunct therapy for secondary prevention in patients with coronary artery disease, mainly in populations with coronary artery bypass graft (CABG) and percutaneous coronary intervention. Thus, the increasing number of cardiac surgeries along the years is enlarging the participation of patients in cardiac rehabilitation programs. Encouraging exercise-based cardiac rehabilitation might decreases in-hospital stay, speeds returns to work and reduces costs in public health. Recently, two training modalities of exercise gained much atention in cardiac rehabilitation programs: continuous exercise and high-intensity interval aerobic training (HIIAT). The aim of this chapter is to review the efects of HIIAT in patients that undergone to CABG or other cardiac surgeries regarding clinical and physiological parameters such as death, cardiovascular outcomes, aerobic capacity, anaerobic capacity, quality of life and other parameters, beyond to evaluate the feasibility and safety of HIIAT in this patient's group.

“…This finding is clinically significant as recent studies have shown that performing higher intensity exercise is associated with greater health benefits when compared to moderate intensity exercise. (58) The reported benefits in these studies are increased cardiorespiratory fitness, (190)(191)(192)(193)(194)(195)(196)(197)(198) mitochondrial biogenesis, (192,196) improved ejection fraction and stroke volume, (193,197) suppression of fatty acid uptake and lipogenesis (192) and an increase in flow mediated dilatation, suggesting improved endothelial function. (191)(192)(193)196) The CKD population have demonstrated reductions or impaired function in each of the above parameters that can potentially be improved with HIIT.…”

Chronic kidney disease (CKD) patients have a shorter life expectancy than healthy individuals, from the premature development of cardiovascular disease due to traditional and non-traditional risk factors. It is therefore pertinent that management of CKD be aimed at modifying these cardiovascular disease risk factors. Exercise therapy, in particular aerobic exercise, in the end stage kidney disease population has been shown to decrease cardiovascular disease risk factors and subsequent cardiovascular disease. However, Section 2 contains the second trial that investigated the feasibility and efficacy of a 12 week HIIT program in CKD patients. Recruitment for the HIIT study was through participants who had completed the LM3 study.Chapter 1 provides an introduction to the studies, including the aims of the thesis. Topics reviewed include; pathophysiology of CKD, exercise capacity, autonomic dysfunction, haemoglobin, muscle atrophy, oxidative stress, inflammation, blood lipids and HIIT. Section 1 starts with the detailed methods of the LM3 study (Chapter 2). Further methods applicable to specific studies are reported in the relevant chapter.Chapter 3 investigates the determinants of reduced muscle strength at baseline through a cross-sectional analysis of the LM3 study. This study identified the association of oxidative 3 stress with low muscle strength and reduced lean mass. The relationship was independent of known influences on muscle mass and strength.The feasibility and determinants of the LI group participating in higher intensity exercise training in the first 12 months of the LM3 study was investigated in Chapter 4. The findings identified that higher intensity exercise training was indeed feasible in the CKD cohort, with the number of participants reporting higher intensity exercise increasing from 20% to 43%.Reported higher intensity exercise during the LI was also associated with the greatest exercise capacity at 12 months. Furthermore, the analysis identified haemoglobin to be the greatest predictor of individuals reporting higher intensity exercise.Chapter 5 investigates the agreement between creatinine and cystatin-C estimated glomerular filtration rate (eGFR) measurements in patients completing 12 months of the LM3 study. This chapter explores whether discrepancies in the CKD Epidemiology Collaboration (CKD-EPI)cystatin-C, CKD-EPIcreatinine and modification of diet in renal disease (MDRD) eGFR equations occur after an exercise intervention. It was identified that cystatin-C based eGFR measurements were considerably lower than creatinine based eGFR measurements. Despite this discrepancy at baseline, the agreement between the different GFR estimates did not change after exercise training.Chapter 6 contains the main study from LM3, which investigates the changes in cardiorespiratory fitness, exercise capacity, functional capacity, blood biochemistry, anthropometry measures and other cardiovascular disease risk factors after 3 years of LI compared to the control group. The primary finding from this...
