Explore the emerging field of free radical biology, exercise, and aging with this definitive reference. Free Radicals in Exercise and Agingaddresses the current debate regarding whether free radicals released during exercise accelerate the aging process. It explains how free radicals can serve as important regulators of aerobic processes, and it clarifies the importance of exercise in increasing the efficiency of the antioxidant and oxidative repair systems. Mounting research data indicate that free radicals are involved in a variety of physiological and pathophysiological processes. This book focuses on exercise-induced adaptation. In general, a person's ability to adapt to internal and external changes decreases during the aging process. However, by continually exposing the body to different challenges, regular exercise triggers an adaptation process that keeps the body and mind fit. Free Radicals in Exercise and Agingelucidates the role of free radical species in regulating this process. This text is also one of the first to provide an in-depth review of skeletal muscle oxidative stress and aging. This issue is pivotal because muscle serves such a critical role in mobility and normal life. Free Radicals in Exercise and Aging shares the most current understanding of how reactive oxygen species influence the biology of skeletal muscles. It explores some of the unique characteristics that skeletal muscle displays during aging, both in terms of free radical production and with regard to antioxidant systems. The implications of this research are far-reaching. Mutation of DNA is linked very closely to cancer, and if regular exercise improves the regulation of the antioxidant systems and the oxidative damage repair system, these mechanisms may be a very important tool against this deadly disease. This research-oriented text presents the latest information on the subject. It reviews and critiques current literature and provides critical information for exercise physiologists, sports medicine specialists, sport nutritionists, and gerontologists.

Among the various theories proposed to account for the process of aging, the free radical theory is of practical interest since it includes the possibility of retarding this process by administrating natural or synthetic antioxidants and free radical scavengers. The book "Free Radicals and Aging" summarizes knowledge accumulated during recent years in 42 reviews written by experts in the field. Aspects of free radical involvement in the intrinsic aging process and in age-related diseases, as well as the importance of the pro-antioxidant balance throughout life are discussed. Epidemiological studies from several European countries are reported showing correlations between low plasma levels of essential antioxidants and the occurence of coronary heart disease, cancer and cataract formation. Appropriate nutrition as well as prophylactic and therapeutic use of antioxidants are considered. This book represents a milestone in the field of age-related free radical biology and medicine.

Oxidative stress and aging Over the past several years there has been an extraordinarily rapid growth in our knowledge of free radical chemistry and its possible involvement in both normal essential biology and age related disease and dysfunction. Much of this growth in the traditionally separate sciences of chemistry and molecular gerontology occurred independently, with little interaction or communi cation between the scientists working in these two fields. In view of the growing maturity of the two fields and the potential importance of advancing our knowledge in the area of oxidative stress and aging, we perceived a critical need to organize an international conference the "First Inter national Conference on Oxidative Stress and Aging" in Hawaii in 1994 to bring together the world's leading scientists in the fields of reactive oxygen species and molecular gerontology. The objective of this conference was to provide a unique opportunity for scholars working in these two related and rapidly growing fields to participate in the exchange, integration, and synthesis of new concepts and ideas, to engage in constructive criticism and to initiate new collaborative research projects. The conference focused on the molecular and cellular aspects of aging as related to oxidative stress. It was one of the largest and most comprehensive international conferences held in molecular gerontology. At this conference a call was made for submission of papers to be used in the publication of a book covering the major contributions of the meeting.

Extensively revised and updated to reflect the current state of knowledge in the study of aging, this Fourth Edition offers a complete profile of the aging process at all levels, from molecules and cells to demography and evolution. Written by international experts in current basic and clinical aging research, this text includes aspects of individual, comparative, and differential aging, and discussions of theories and mechanisms of aging. This invaluable reference illustrates how bodily systems, organs, and functions are affected with aging, describes how genetic and environmental factors influence age-related changes, and addresses some of the clinical consequences of these changes for health and longevity. Well illustrated, with numerous tables and graphs, this book presents up-to-date information from internationally renowned experts in various bio-medical fields.

Experts in the fields of energy metabolism, aging and oxidative stress provide an integrated view of how mechanisms involved in regulating energy metabolism are linked to fundamental processes of aging including cellular stress resistance and free radical production. During evolution signal transduction pathways and organ systems have been optimised for the efficient seeking, ingestion, storing and using of energy. These signalling pathways play prominent roles in lifespan determination with insulin and related signalling pathways being prime examples. The authors consider how lifespan and healthspan can be extended through knowledge of energy metabolism with the experimental model of dietary restriction being one example. The information in this volume of ACAG will foster novel approaches and experiments for further understanding the roles of energy metabolism in aging and disease.

For many, the terms aging, maturation and senescence are synonymous and used interchangeably, but they should not be. Whereas senescence represents an endogenously controlled degenerative programme leading to plant or organ death, genetiC aging encompasses a wide array of passive degenerative genetiC processes driven primarily by exogenous factors (Leopold, 1975). Aging is therefore considered a consequence of genetiC lesions that accumulate over time, but by themselves do not necessarily cause death. These lesions are probably made more severe by the increase in size and complexity in trees and their attendant physiology. Thus while the withering of flower petals following pollination can be considered senescence, the loss of viability of stored seeds more clearly represents aging (Norden, 1988). The very recent book "Senescence and Aging in Plants" does not discuss trees, the most dominant group of plants on the earth. Yet both angiospermic and gymnospermic trees also undergo the above phenomena but less is known about them. Do woody plants senesce or do they just age? What is phase change? Is this synonymous with maturation? While it is now becoming recognized that there is no programmed senescence in trees, senescence of their parts, even in gymnosperms (e. g. , needles of temperate conifers las t an average of 3. 5 years), is common; but aging is a readily acknowledged phenomenon. In theory, at least, in the absence of any programmed senescence trees should -live forever, but in practice they do not.
