Severe-intensity exercise describes specific exercise intensities where contraction-induced metabolic markers (e.g., inorganic phosphate, H+, pH) do not reach steady-state, but continue to change until task failure is reached. It has been found that the rates of change in these markers are intensity-dependent, but reach similar values at the limit of exercise tolerance (T[subscript lim]). Therefore, the amount of work done at T[subscript lim] is not different across severe-intensity work rates. However, we have previously shown evidence of a supra-severe-intensity domain (i.e., extreme-intensity exercise), where the amount of work performed at T[subscript lim] is significantly lower than during severe-intensity exercise. Further, the mechanisms limiting exercise tolerance reverse at significantly faster rates during recovery from extreme-intensity exercise compared to following severe-intensity exercise. Therefore, the overall aims of this dissertation were to examine the differences in exercise tolerance between severe- and extreme-intensity exercise as well as measure important neuromuscular recovery immediately following exercise cessation in order to elucidate what potential mechanistic differences may be contributing to the accelerated accumulation of fatigue. In our first investigation (Chapter 2), we demonstrated that maximal voluntary contraction (MVC) was significantly decreased following severe- and extreme-intensity exercise. MVC recovery was apparent in both men and women following severe-intensity exercise, with little to no recovery following extreme-intensity exercise. Further, peripheral fatigue, estimated by reductions in potentiated twitch force (Q[subscript pot]), did not develop to the same degree following extreme- compared to severe-intensity exercise and showed significant recovery within 90 s in men and 150 s in women. To further investigate sex differences in neuromuscular fatigue development and force recovery following extreme-intensity exercise, in our second investigation (Chapter 3), we found no differences in W'[subscript sev], or W'[subscript ext], between men and women. MVC and Q[subscript pot] forces recovered faster following extreme-intensity exercise compared to following severe-intensity exercise, with women recovering to values not significantly different from baseline sooner than in men. Further, it was evident that men accumulated greater peripheral fatigue during submaximal exercise than women; however, there were no sex differences following near-maximal (90% MVC) exercise. In our final pilot investigation (Appendix A), we examined the potential effects of creatine monohydrate supplementation on extreme-intensity exercise tolerance. Although no statistical differences were found in MVC, Q[subscript pot], W'[subscript sev], or W'[subscript ext], individuals showed large variability in responses to creatine supplementation, with creatine supplementation having profound effects on exercise tolerance in some, but not all, individuals. Collectively, this dissertation provides novel findings and improves our understanding of exercise intensity domain-dependent fatigue mechanisms and their contributions, especially during extreme-intensity exercise. Further, we provide evidence of differences in neuromuscular recovery between men and women, which are likely to have important implications regarding sex-dependent-mechanisms limiting exercise tolerance. Therefore, it is important to consider the differences between men and women regarding the mechanisms and level of fatigue and time course of recovery when developing exercise prescription (e.g., work rate intensity, recovery between exercise modalities) for specific populations.

In the past, ‘traditional’ moderate-intensity continuous training (60-75% peak heart rate) was the type of physical activity most frequently recommended for both athletes and clinical populations (cf. American College of Sports Medicine guidelines). However, growing evidence indicates that high-intensity interval training (80-100% peak heart rate) could actually be associated with larger cardiorespiratory fitness and metabolic function benefits and, thereby, physical performance gains for athletes. Similarly, recent data in obese and hypertensive individuals indicate that various mechanisms – further improvement in endothelial function, reductions in sympathetic neural activity, or in arterial stiffness – might be involved in the larger cardiovascular protective effects associated with training at high exercise intensities. Concerning hypoxic training, similar trends have been observed from ‘traditional’ prolonged altitude sojourns (‘Live High Train High’ or ‘Live High Train Low’), which result in increased hemoglobin mass and blood carrying capacity. Recent innovative ‘Live Low Train High’ methods (‘Resistance Training in Hypoxia’ or ‘Repeated Sprint Training in Hypoxia’) have resulted in peripheral adaptations, such as hypertrophy or delay in muscle fatigue. Other interventions inducing peripheral hypoxia, such as vascular occlusion during endurance/resistance training or remote ischemic preconditioning (i.e. succession of ischemia/reperfusion episodes), have been proposed as methods for improving subsequent exercise performance or altitude tolerance (e.g. reduced severity of acute-mountain sickness symptoms). Postulated mechanisms behind these metabolic, neuro-humoral, hemodynamics, and systemic adaptations include stimulation of nitric oxide synthase, increase in anti-oxidant enzymes, and down-regulation of pro-inflammatory cytokines, although the amount of evidence is not yet significant enough. Improved O2 delivery/utilization conferred by hypoxic training interventions might also be effective in preventing and treating cardiovascular diseases, as well as contributing to improve exercise tolerance and health status of patients. For example, in obese subjects, combining exercise with hypoxic exposure enhances the negative energy balance, which further reduces weight and improves cardio-metabolic health. In hypertensive patients, the larger lowering of blood pressure through the endothelial nitric oxide synthase pathway and the associated compensatory vasodilation is taken to reflect the superiority of exercising in hypoxia compared to normoxia. A hypoxic stimulus, in addition to exercise at high vs. moderate intensity, has the potential to further ameliorate various aspects of the vascular function, as observed in healthy populations. This may have clinical implications for the reduction of cardiovascular risks. Key open questions are therefore of interest for patients suffering from chronic vascular or cellular hypoxia (e.g. work-rest or ischemia/reperfusion intermittent pattern; exercise intensity; hypoxic severity and exposure duration; type of hypoxia (normobaric vs. hypobaric); health risks; magnitude and maintenance of the benefits). Outside any potential beneficial effects of exercising in O2-deprived environments, there may also be long-term adverse consequences of chronic intermittent severe hypoxia. Sleep apnea syndrome, for instance, leads to oxidative stress and the production of reactive oxygen species, and ultimately systemic inflammation. Postulated pathophysiological changes associated with intermittent hypoxic exposure include alteration in baroreflex activity, increase in pulmonary arterial pressure and hematocrit, changes in heart structure and function, and an alteration in endothelial-dependent vasodilation in cerebral and muscular arteries. There is a need to explore the combination of exercising in hypoxia and association of hypertension, developmental defects, neuro-pathological and neuro-cognitive deficits, enhanced susceptibility to oxidative injury, and possibly increased myocardial and cerebral infarction in individuals sensitive to hypoxic stress. The aim of this Research Topic is to shed more light on the transcriptional, vascular, hemodynamics, neuro-humoral, and systemic consequences of training at high intensities under various hypoxic conditions.

Background and Aim: The power-duration relationship accurately predicts exercise tolerance for constant power exercise performed in the severe intensity domain. At intensities above critical power (CP), the power-duration relationship establishes a hyperbolic curve. However, the prediction of exercise tolerance is currently unclear for work rates within the extreme intensity domain (durations 2min). We hypothesized that the power-duration relationship deviates from a linear 1/time relationship for WRs within the extreme intensity domain. Methods: Six men completed nine bilateral knee-extension tests on non-consecutive days and then performed 3 exercise tests in the severe intensity domain (S1-S3; T[subscript lim]2-15min) and 4 in the extreme domain at 60%, 70%, 80%, and 90%1RM (T[subscript lim]

In the last 50 years, classical breeding has played a significant role in achieving higher crop productivity, but major crops have reached a plateau in their yield potential. Therefore, the current focus for sustainable intensification of agriculture is the use of biotechnological approaches to enhance the yield potential by combating the yield losses that occur due to abiotic stresses. The abiotic stresses are governed by multigenes, and therefore, a holistic approach is needed to get success in imparting stress tolerance to enhance the yield potential of our crops. Plants face multiple stress conditions during their life stages and adopt several physiological, biochemical, and molecular strategies to combat that, which are sometimes not sufficient to survive, particularly crop plants. The climate change era has created a need to understand the abiotic stresses in a holistic way. Therefore, a deep understanding of multiple abiotic stress mechanisms is necessary to develop crops tolerant to climate fluctuation. With this background, the outline of this book covers the following features: • Agriculture sustainability and molecular understanding of multiple stress tolerance • Systems biology for life-history strategies, conventional and genomic approaches above and underground • Genetic resources and molecular understanding of seed priming • Molecular signaling compounds, cell signal transduction, and crosstalk between plant growth hormones and regulators • Roles Transcription factors, LEA proteins, reactive oxygen species and alternative oxidase • Genome editing, metabolomics, and ‘omics’ technologies
