Download or read book Oxidative Stress in Skeletal Muscle written by Reznick and published by Birkhäuser. This book was released on 2012-12-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skeletal muscle consumes significant amounts of oxygen, and its oxygen flux increases significantly under conditions of exercise and muscle contraction. This makes the muscle vulnerable to oxidative stress since concomitantly with the increase of oxygen flow there is an increase of free oxygen radicals which are a byproduct of muscle respiration. A number of studies in the last decade have documented the involvement of free oxygen radicals in exercising muscles. The consequences of muscle oxidative stress have resulted mainly in increased muscle protein oxidation, elevation of lipid peroxidation, and depletion of muscle antioxidants. The mechanisms of this oxidative stress are under extensive investigation in laboratories around the world and are topics of the chapters in this volume. This book is intended for professionals who are interested in muscle function, physiology, pathophysiology and well-being, such as therapists, trainers and medical professionals as well as for researchers in the field of muscle physiology.

This book was released on 2007 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the effects of a combined antioxidant supplementation on myocardial protein carbonyls (PC) and malondialdehyde (MDA) in rats after aerobic downhill running. Sixty-six male Sprague-Dawley rats were randomly assigned to either a normal diet or antioxidant supplemented diet (2,000 mg vitamin C + 1,000 IU vitamin E/kg diet) for 2 weeks. Exercised rats (N=48) ran on a rodent treadmill for 90 min at a speed of 16 m/min and -16 degrees downhill grade. Rats were killed either at rest, immediately, 2 hrs, or 48 hrs post exercise. Rested rats were killed at the same times as the exercised rats all between 0700-1000 hrs. Ventricular tissue was analyzed for two markers of oxidative stress, PC and MDA. Only exercised rats that completed the 90 min run were included in the PC and MDA data analysis. There was a significant time main effect for PC concentration (p=0.02) but post-hoc analysis indicated no specific time differences. However, PC approached significance (p=0.064) for the 2 hr post exercise time. There were no significant treatment or time*treatment effects for PC. MDA results showed no significant time, treatment or time*treatment effect. These data indicate that downhill running with modest intensity does not significantly increase oxidative stress in hearts as indicated by PC and MDA but a larger sample size is needed to confirm these results.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together some of the leading researchers in the actively investigated field of oxidative stress, an area of study which is of importance to human health and disease. It examines oxidative stress in a variety of models, at rest and after exercise, in young and old. Key concepts of oxidative stress, exercise and aging are presented in clear and easy-to-understand terms. Oxidative stress in different types of exercises OCo isometric, isotonic and sports OCo is explained in detail, with several chapters focusing on acute and chronic adaptations of skeletal muscles following both aerobic and non-aerobic exercises. The book includes current knowledge of the underlying mechanisms influencing health and disease processes associated with oxidative stress.

Download or read book Antioxidants in Sport Nutrition written by Manfred Lamprecht and published by CRC Press. This book was released on 2014-09-17 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of antioxidants in sports is controversial due to existing evidence that they both support and hinder athletic performance. Antioxidants in Sport Nutrition covers antioxidant use in the athlete ́s basic nutrition and discusses the controversies surrounding the usefulness of antioxidant supplementation. The book also stresses how antioxidants may affect immunity, health, and exercise performance. The book contains scientifically based chapters explaining the basic mechanisms of exercise-induced oxidative damage. Also covered are methodological approaches to assess the effectiveness of antioxidant treatment. Biomarkers are discussed as a method to estimate the bioefficacy of dietary/supplemental antioxidants in sports. This book is useful for sport nutrition scientists, physicians, exercise physiologists, product developers, sport practitioners, coaches, top athletes, and recreational athletes. In it, they will find objective information and practical guidance.
Download or read book Handbook of Oxidants and Antioxidants in Exercise written by C. Sen and published by Elsevier. This book was released on 2000-02-16 with total page 1219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the science of exercise dates back to the time of ancient Greece. Today exercise is viewed not only as a leisurely activity but also as an effective preventive and therapeutic tool in medicine. Further biomedical studies in exercise physiology and biochemistry reports that strenuous physical exercise might cause oxidative lipid damage in various tissues. The generation of reactive oxygen species is elevated to a level that overwhelms the tissue antioxidant defense systems resulting in oxidative stress. The Handbook of Oxidants and Antioxidants in Exercise examines the different aspects of exercise-induced oxidative stress, its management, and how reactive oxygen may affect the functional capacity of various vital organs and tissues. It includes key related issues such as analytical methods, environmental factors, nutrition, aging, organ function and several pathophysiological processes. This timely publication will be of relevance to those in biomedical science and was designed to be readily understood by the general scientific audience.

Book excerpt: Aging is associated with a decline in psychomotor and cognitive function. Interventions such as exercise and antioxidants supplementation when investigated independently have been beneficial counteracting oxidative stress and improving brain function in both human and animals. A large number of health conscious individuals often combine exercise with vitamin supplementation, anticipating a synergistic effect maximizing their performance. While some studies reported additive effects, others have also indicated a potential for an antagonistic action of the antioxidants on the beneficial effects of exercise. To date, it has not been well established what the nature of the interaction between antioxidant supplementation and exercise is in terms of functional outcomes and whether age will influence the outcomes. The purpose of this study was to determine if combination of antioxidant supplementation, and moderate exercise could ameliorate psychomotor and cognitive performance of young and old male mice Using vitamins C and E and a treadmill-based forced exercise in young and old C57BL/6J mice, we explored the nature of that interaction on functional and biochemical outcomes. We examined the mice for spatial learning and memory, working memory and executive function, coordinated running performance, muscular reflexes, spontaneous locomotor activity, anxiety and muscle strength. Our data suggested that the male mice exhibited age-associated declines in psychomotor and cognitive performance. Antioxidants supplementation worsened the cognitive flexibility of old mice but improved the depression-like symptoms in young mice. Overall, exercise training reversed the age-related declines in reflexes and balance of old mice, and improved strength and associative learning of young mice only. Furthermore, combination of exercise and antioxidant improved reflexes, motor and cognitive performance, but additive or antagonistic effects of antioxidants on the beneficial effects of exercise were not observed. Hence we can conclude that, combining antioxidants and exercise may not be provide any additional benefit in reversing age-related functional impairments.
