This book was released on 2011 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability to supply cellular energy in the form of adenosine triphosphate (ATP) by oxidative phosphorylation is critical to maintaining muscle function and health. While conventional endurance exercise training has proven effective at increasing the maximal capacity for oxidative phosphorylation (Vmax), it is not known whether exercise training stimulates mitochondrial ATP synthesis in resting muscle (Vrest). Recently, short-term high-intensity interval training (HIT) training has shown potent effects on Vmax . However, little is known about (1) the effects of short-term HIT on Vrest, and (2) the time course of adaptations in V rest and Vmax following short-term HIT. Healthy young males were recruited to participate in a 2-week training intervention (6 training sessions). Each session consisted of 4-6 bouts of 30-s sprints on a cycle ergometer. Phosphorus magnetic resonance spectroscopy was used to measure Vrest and Vmax in vivo in vastus lateralis: (i) prior to, (ii) 15 hours after a single session of exercise training, and (iii) after completing 6 sessions of exercise training. Two weeks of training increased peak whole-body oxygen consumption (35.8 ± 1.4 to 39.3 ± 1.6 ml·min-1 ·kg-1, p=0.01) and exercise capacity (217.0 ± 11.0 to 230.5 ± 11.7 W, p=0.04) on the cycle ergometer. While Vmax was unchanged after a single session of HIT, completion of six training sessions resulted in increased muscle oxidative capacity (p

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 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.

This book was released on 2009 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Which of the following will yield the fastest measurable change in performance and/or body composition? (A) changes in training. (B) changes in diet. (C) use of sports supplements. (D) they all work equally well. If you answered 'C,' go to the head of the class. That's right; the proper use of sports supplements can produce changes in minutes (e.g. caffeine), days (e.g. creatine) and weeks (e.g. beta-alanine). Yet we are bombarded by muddled thinking from the mainstream media telling us that 'creatine causes cramps,' 'high protein diets are bad for your kidneys,' 'supplements aren't needed as long as you eat a balanced diet' and other ideas that are void of data. Sports Nutrition & Performance Enhancing Supplements (eds. Abbie Smith-Ryan PhD CSCS*D CISSN and Jose Antonio PhD FNSCA FISSN. Linus Publications) is a focused resource that will give you the latest sports nutrition science, and eradicate the intellectually lazy positions held so dearly by the anti-supplement crowd."--Amazon.

Download or read book The Pathway for Oxygen written by Ewald R. Weibel and published by Harvard University Press. This book was released on 1984 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is rare indeed for one book to be both a first-rate classroom text and a major contribution to scholarship. The Pathway for Oxygen is such a book, offering a new approach to respiratory physiology and morphology that quantitatively links the two. Professionalism in science has led to a compartmentalization of biology. Function is the domain of the physiologist, structure that of the morphologist, and they often operate with vastly disparate concepts and procedures. Yet the performance of the respiratory system depends both on structural and on functional properties that cannot be separated. The first chapter of The Pathway for Oxygen engages the student with the design and function of the vertebrate respiratory organs from a comparative viewpoint. The second chapter adds to that foundation the link between cell energetics and oxygen needs of the whole animal. With Chapter 3 the excitement begins--new ideas, fresh attacks on old problems, and a fuller account of the power of the quantitative approach Dr. Weibel has pioneered. The Pathway for Oxygen will be read eagerly by medical students, graduate students, advanced undergraduates in zoology--and by their professors.

Available in PDF, EPUB and Kindle. Book excerpt: Considering the increasing global prevalence of overweight and obesity and their propensity for disease, this study was undertaken in an attempt to optimize exercise prescription for this at-risk group by determining if the benefits associated with interval training occur in an intensity dependent manner. 19 sedentary, overweight males (Age: 22.7 ± 3.9 yrs, BMI: 31.4 ± 2.6 kg/m2, WC: 106.5 ± 6.6 cm) performed interval training for three weeks at either 70% or 100% of their peak work rate on a cycle ergometer. Aerobic capacity measurements, time to completion trials, muscle biopsies, and fasted blood samples were all performed pre and post training. Analyses of aerobic capacity and exercise performance demonstrate greater improvements made in the 100% compared to the 70% group, while measures of skeletal muscle oxidative capacity indicate equivalent changes between groups. Taking into account the similar increases in mitochondrial content in both groups and understanding the influence of both oxygen supply and demand in determining maximal oxygen consumption, the greater increases in aerobic capacity achieved by the 100% group may be the result of enhanced cardiovascular adaptations. These findings suggest that some of the health benefits associated with interval exercise may be intensity dependent. Therefore, there may be additional benefit to exercise at higher intensities.

Download or read book Science and Development of Muscle Hypertrophy written by Brad J. Schoenfeld and published by Human Kinetics. This book was released on 2020-05-08 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science and Development of Muscle Hypertrophy, Second Edition, is the most comprehensive resource on muscle hypertrophy in the world. Written by Brad Schoenfeld, PhD, an internationally renowned expert on muscle hypertrophy, this book is the definitive resource for strength and conditioning professionals, personal trainers, sport scientists, researchers, and exercise science instructors who are seeking information regarding muscle hypertrophy, including the mechanism of its development, how the body structurally and hormonally changes when exposed to stress, ways to most effectively design training programs, and nutritional guidelines for eliciting hypertrophic changes. This new edition offers more than 1,000 references and applied guidelines. Two all-new chapters deliver practical content on the measurement of muscle hypertrophy and advanced training practices. Readers will learn various methods by which hypertrophy is measured, including site-specific measures (circumference measures, MRI, CT, and ultrasound), indirect measures (underwater weighing, DXA, BIA, ADP, and skinfolds), and histological measures (biopsy), as well as the strengths and limitations of each modality. The new edition also provides guidance for achieving greater training volumes with training practices that maximize the individual’s genetic potential to gain muscle. No other resource offers a comparable amount of content solely focused on the science of muscle hypertrophy and its application to designing training programs. The full-color book offers several features to make the content accessible to readers: Research Findings sidebars highlight the aspects of muscle hypertrophy currently being examined to encourage readers to re-evaluate their knowledge and ensure their training practices are up to date. Practical Applications sidebars outline how to apply the research conclusions for maximal hypertrophic development. Comprehensive subject and author indexes optimize the book’s use as a reference tool. Although muscle hypertrophy can be attained through a range of training programs, this book allows readers to understand and apply the specific responses and mechanisms that promote optimal muscle hypertrophy. It explores how genetic background, age, sex, and other factors have been shown to mediate the hypertrophic response to exercise, affecting both the rate and the total gain in lean muscle mass. Sample programs show how to design a three- or four-day-per-week undulating periodized program and a modified linear periodized program for maximizing muscular development. Science and Development of Muscle Hypertrophy is an invaluable resource for those seeking to maximize hypertrophic gains for themselves or their athletes or clients and for those searching for the most comprehensive and authoritative research in the field.

Download or read book Exercise and Diabetes written by Sheri R. Colberg and published by American Diabetes Association. This book was released on 2013-05-30 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical movement has a positive effect on physical fitness, morbidity, and mortality in individuals with diabetes. Although exercise has long been considered a cornerstone of diabetes management, many health care providers fail to prescribe it. In addition, many fitness professionals may be unaware of the complexities of including physical activity in the management of diabetes. Giving patients or clients a full exercise prescription that take other chronic conditions commonly accompanying diabetes into account may be too time-consuming for or beyond the expertise of many health care and fitness professionals. The purpose of this book is to cover the recommended types and quantities of physical activities that can and should be undertaken by all individuals with any type of diabetes, along with precautions related to medication use and diabetes-related health complications. Medications used to control diabetes should augment lifestyle improvements like increased daily physical activity rather than replace them. Up until now, professional books with exercise information and prescriptions were not timely or interactive enough to easily provide busy professionals with access to the latest recommendations for each unique patient. However, simply instructing patients to “exercise more” is frequently not motivating or informative enough to get them regularly or safely active. This book is changing all that with its up-to-date and easy-to-prescribe exercise and physical activity recommendations and relevant case studies. Read and learn to quickly prescribe effective and appropriate exercise to everyone.

Download or read book Investigation of Metabolic Responses to Exercise in Adolescents and Adults During High Intensity Exercise and Recovery written by Rebecca Willcocks and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Children and adolescents are thought to use oxidative metabolism to a greater extent than adults during high intensity exercise. The studies reported in this thesis examine the nature and implications of age-related differences in muscle metabolism during high intensity exercise and recovery. Chapter 4 concluded that during heavy intensity exercise, phosphocreatine (PCr) kinetics did not differ with age or sex, while Chapter 5 revealed that during very heavy intensity exercise, the fundamental t was slower and slow component amplitude greater in men compared with adolescent boys, indicating that exercise intensity might play a role in determining age-related differences in muscle metabolism. In Chapter 6, two bouts of very heavy intensity exercise were completed, and prior exercise reduced the PCr slow component amplitude in men but not boys. Deoxyhaemoglobin (HHb) kinetics was faster in adolescents compared with adults during both heavy and very heavy intensity exercise, indicating that matching of oxygen delivery to oxygen utilisation is less precise at the onset of exercise in adolescents compared with adults. PCr recovery from high intensity exercise was faster in boys than men, but not different in girls and women, as described in Chapter 7. The speed of PCr recovery was correlated with maturity in adolescents, but was not correlated with end-exercise [PCr] or pH. Two different tests to measure mitochondrial capacity in adolescents were evaluated in Chapter 8, and a fitted curve and gated test were both used to determine PCr recovery kinetics. Finally, in Chapter 9, age-related differences in muscle metabolism and oxygenation during fatiguing exercise were examined; a strong trend for greater fatigue in adults compared with adolescents was accompanied by greater metabolic perturbation in adults. Overall, these data show that muscle metabolism and oxygenation differs between adolescents and adults during and following very high intensity exercise.

Download or read book 15 Minutes to Fitness written by Vincent Ben Bocchicchio and published by SelectBooks, Inc.. This book was released on 2017-01-17 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Do you ever feel like a hamster, spinning on a wheel in an endless loop and getting nowhere when it comes to your health and fitness? Are you working out regularly and cutting calories but seeing no real improvements? Does it feel like you will never lose those last 10 or 20 pounds? Or do you feel as if you simply don’t have the time required to lose the fat and get into shape? Imagine if you could have the blueprint for the most efficient form of exercise to keep your body healthy and fit and an eating plan to satisfy hunger, taste, and health. Well, now you can. The best part? It will only require 15 minutes of exercise, twice a week, paired with a controlled-carb diet, and on the average, you will lose 10 pounds of fat within five weeks. It’s hard to believe, but it works—and 15 Minutes to Fitness:Dr. Ben's SMaRT plan for total Fitness will not only show you how to do it but also explain why it works. If this sounds like just another “new exercise secret,” please be assured that it is most certainly not. The foundation of this program is based on years of study, observation, and practice, and it has delivered real, measurable results in the overwhelming majority of those who have tried it. Dr. Vincent “Ben” Bocchicchio has spent the last 40 years in the fitness and health field, and as he approaches 70, people are still shocked to hear that he only spends 14 minutes twice a week on working out. But it’s true. With only 7 percent body fat, he is often asked what the secret is and if there's a “magic bullet.” The answer would be that the magic bullet is knowledge. And now with this book you will understand why genetically our bodies require simple and limited exercise exposure and how you can follow this optimal pattern yourself. The fact is that as humans we are hard-wired to exercise our bodies in very specific ways to reap the highest level of health benefits. I will provide the simple scientific argument for why my combination of high intensity exercise and controlled carbohydrate eating is the most effective means for burning fat, so that you can better understand exactly why this works. Exercise and diet are the two most powerful tools available for attaining high levels of health and function, and 15 Minutes to Fitness will show you just how little it actually takes to achieve a maximum response.
