Download or read book Science and Application of High Intensity Interval Training written by Laursen, Paul and published by Human Kinetics. This book was released on 2019 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: The popularity of high-intensity interval training (HIIT), which consists primarily of repeated bursts of high-intensity exercise, continues to soar because its effectiveness and efficiency have been proven in use by both elite athletes and general fitness enthusiasts. Surprisingly, few resources have attempted to explain both the science behind the HIIT movement and its sport-specific application to athlete training. That’s why Science and Application of High-Intensity Interval Training is a must-have resource for sport coaches, strength and conditioning professionals, personal trainers, and exercise physiologists, as well as for researchers and sport scientists who study high-intensity interval training.

Download or read book Respiratory Physiology written by John Burnard West and published by . This book was released on 1996 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Present-day respiratory physiology stems largely from the explosion of ideas which took place during and after World War II. A number of the major players are still active, but the opportunity to prepare a personal history of this branch of medicine will soon be lost. In a sense then, this book offers an exceptional, even unique, opportunity. We are offered a first-hand chronicle of the advancements made in respiratory physiology in the course of this century by one of the principal figures in the field. The volume covers every aspect of the evolution of this important area of knowledge: morphology, gas exchange and blood flow, mechanics, control of ventillation, and comparative physiology. Some of the chapters are personal accounts of the development of respiratory physiology as observed by the author. It is hoped that what is lost in objectivity by this approach is more than made up by the captivating insights provided by the author into the process of scientific research and discovery.
Download or read book High Intensity Exercise in Hypoxia Beneficial Aspects and Potential Drawbacks written by Olivier Girard and published by Frontiers Media SA. This book was released on 2018-01-25 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Effects of High intensity Intermittent Exercise on Energy Intake and Its Regulation written by Yueren Aaron Sim and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated] It is well established that exercise plays an important role in the management of overweight and obesity. In the past, this was primarily attributed to the direct contribution of exercise to energy expenditure, however it is becoming increasingly evident that exercise may also influence appetite and energy intake. Importantly, the precise effect of exercise on appetite and energy intake appears to be influenced by specific characteristics of the exercise. In particular, high-intensity exercise appears to have beneficial (anorexic) effects on appetite and energy intake. Prolonged and continuous high-intensity exercise may however, not be tolerable and sustainable in an inactive and overweight population. An alternative may be the use of high-intensity, intermittent exercise that involves short bouts of high-intensity exercise interspersed with periods of exercise at lower intensities. However, the effects of high-intensity, intermittent exercise on energy intake and appetite regulation is not known. The research presented in this thesis examines the acute and longer term influence of high-intensity, intermittent exercise compared with traditional moderate-intensity, continuous exercise on subsequent energy intake, perceptions of appetite and appetite-related blood variables in sedentary, overweight men.
