Book excerpt: Popular science at its most exciting: the breaking new world of chronobiology - understanding the rhythm of life in humans and all plants and animals. The entire natural world is full of rhythms. The early bird catches the worm -and migrates to an internal calendar. Dormice hibernate away the winter. Plants open and close their flowers at the same hour each day. Bees search out nectar-rich flowers day after day. There are cicadas that can breed for only two weeks every 17 years. And in humans: why are people who work anti-social shifts more illness prone and die younger? What is jet-lag and can anything help? Why do teenagers refuse to get up in the morning, and are the rest of us really 'larks' or 'owls'? Why are most people born (and die) between 3am-5am? And should patients be given medicines (and operations) at set times of day, because the body reacts so differently in the morning, evening and at night? The answers lie in our biological clocks the mechanisms which give order to all living things. They impose a structure that enables us to change our behaviour in relation to the time of day, month or year. They are reset at sunrise and sunset each day to link astronomical time with an organism's internal time.
Download or read book The Athlete s Clock written by Thomas W. Rowland and published by Human Kinetics. This book was released on 2011-04-15 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Athlete’s Clock: How Biology and Time Affect Sport Performance offers an engaging, interdisciplinary consideration of some of the most compelling questions in sport and exercise science. This unique text takes a broad look at the physiological clock, offering students, researchers, coaches, and athletes a unique approach to understanding how various aspects of time affect sport performance. The Athlete’s Clock explores the ways in which time and its relationship to athletic effort can optimize sport performance. Readers can investigate challenging questions such as these: •If physiological responses to training vary rhythmically throughout the day, what is the optimal time of day for training? •If a coach thinks that a high stroke count leads to a better time in a particular swim event, should the athlete go with it? Or is it better to stick to a more intuitively normal cadence? •Do endurance athletes consciously control their pacing, or are they under the control of unconscious processes within the central nervous system? •In what ways do aging and rhythmic biological variations over time control athletic performance? •Can athletes use cognitive strategies to subdue or overcome limits imposed by biological factors out of their control? Readers will find information on the mechanisms by which time influences physiological function—such as running speeds and muscle activation—and how those mechanisms can be used in extending the limits of motor activity. Chapter introductions cue readers to the ideas addressed in the chapter, and sidebars throughout present amusing or unusual examples of sport and timing within various contexts. In addition, take-home messages at the end of each chapter summarize important findings and research that readers may apply in their own lives. Addressing one of the most intriguing questions in sports, a conversational interview with athlete development expert, anthropologist, and sport scientist Bob Malina covers the timely topic of sport identification and talent development. The interview is an engaging discussion of how and when talent identification should take place and how talent development for young, promising athletes might proceed. The text also considers how time throughout one’s life span alters motor function, particularly in the later years. The Athlete’s Clock: How Biology and Time Affect Sport Performance blends physiological, psychological, and philosophical perspectives to provide an intelligent and whimsical look at the effects of timing in sport and exercise. This text seeks to provoke thought and further research that look at the relationship between biology, time, and performance as well as an understanding of and appreciation for the intricacies of human potential.
Download or read book Biological Rhythms written by Vinod Kumar and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Chapters 11 to 14) summarise important features of the biological clock at the level of whole animal covering all vertebrate classes (fish to mammal). Chapters 15 and 16 are on long term (seasonal) rhythms in plants and higher vertebrates. Short term rhythms (ultradian rhythms), the significance of having a clock system in animals living in extreme (arctic) environments, and the diversity of circadian responses to melatonin, the key endocrine element involved in regulation of biological rhythms, have been discussed in Chapters 17 to 19. Finally, a chapter on sensitivity to light of the photoperiodic clock is added which, using vertebrate examples, illustrates the importance of wavelength and intensity of light on circadian and non-circadian functions. A well-known expert writes each chapter. When presenting information, the text provides consistent thematic coverage and feeling for the methods of investigation. Reference citation within the body of the text adequately reflects the literature as subject is developed. A chapter begins with an abstract that enables a reader to know at the first glance the important points covered in that chapter. The chapter concludes with a full citation of references included in the text, which could be useful for further reading. The book ends with a comprehensive subject index that may be useful for quick searches.

Book excerpt: BACKGROUND INFORMATION/INTRO: Circadian rhythms are the body’s biological clock that carries out essential processes. These processes run on a 24-hour cycle which can be disrupted through multiple factors. Disruption of these cycles can lead to a variety of issues including sleep loss, insomnia, changes to mental health, and physical ailments such as cancer, cardiac dysfunction, and sarcopenia. Gene expression in the central clock produces circadian rhythms in the central clock known as the suprachiasmatic nucleus (SCN) as well as in the peripheral tissue. FOS is a neural marker of activity in the SCN METHODS: Four groups of male and female mice (~12 months) were separated into a control group (C), a disrupted and sedentary group (DS), and a disrupted and forced exercise group (DE), and a non-disrupted and forced exercise group (NDE). The circadian disruption (CD) for the DS and DE groups consisted of an accelerated shift work schedule for four weeks. The DE and NDE mice were subjected to forced treadmill running daily at the start of their normal activity period. Immunohistochemistry was completed to observe gene expression in the SCN. RESULTS: A one-way ANOVA revealed a significant between-groups effect (F3,15 = 6.305, P = 0.0056). Post hoc analyses revealed a significant difference between the DNE and NDNE group (P = 0.003). CONCLUSIONS: The CD protocol effectively reduced FOS expression in the SCN. Mice in the DE group displayed increased FOS expression in the SCN that more closely resembled the non-disrupted groups compared to the DNE group.

Download or read book Circadian Physiology written by Roberto Refinetti, PhD. and published by CRC Press. This book was released on 2019-07-17 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long before Apollo 11 blasted off for the moon, astronauts Neil Armstrong, "Buzz" Aldrin and Michael Collins simulated actual space conditions to prepare their bodies for the long voyage to earth's only natural satellite. And before some U.S. professional athletes compete on another continent, they alter their eating and sleeping patterns to adapt themselves for the shift in time zones. Practices such as these are all related to the regulation of the human body's biological rhythms, which are controlled by the 'body clock'. Circadian Physiology highlights the basic processes and latest research findings in circadian biology, and describes how this knowledge applies to the prevention of jet lag and the malaise associated with shift work, the treatment of sleep disorders and depression, the timing for effective administration of medicines, and the planning of astronaut schedules for space exploration. Targeted at life scientists who are not specialists in biological rhythms, the book is also accessible to general readers who have an interest in scientific issues and their applicability to health and business problems. To provide the in-depth understanding of circadian phenomena required for the analysis of actual research data, the author has included software for data analysis and simulation that will allow readers to put into practice the formal knowledge acquired through the disciplinary chapters. With its accessible, up-to-date review of scientific and medical advances, Circadian Physiology is a valuable addition to the growing field of circadian biology.

This book was released on 2023-08-23 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our bodies are symphonies of rhythms. Beneath the hum of life's busy motion, inside the cells of every tissue, molecular oscillations mark time's passage like the world's smallest beating drums. These cellular pulses resonate across scales into larger biological waves – cycling hormones coursing day and night, electrical brain storms waxing and waning, silent marrow churning out blood's metronomic tempo. We are creatures not of static Being, but of Becoming – beings built upon change, growth and decay. Yet unlike random chaos, the change that shapes us flows in patterns anchored deep within our genetic code. Our rhythms of activity and rest, waking and sleeping, eating and fasting, learning and forgetting, sensing and responding have all evolved to turn in sync with the predictable cycles of our spinning planet. Circadian we are, and Ultradian too. But modern life has led us astray. We doused night with artificial light, ate at odd hours, filled waking moments with distraction, turned days into endless work, and mistook convenience for progress. In banishing nature’s rhythms, we damaged our innate temporal order. We disrupted healthy oscillations once harmonized through epochs past. Now we suffer mounting ills. Yet latent within our cells, the ancient rhythms persevere. To flourish, we need but realign: Dim electric nights, welcome natural dawns, move, feast, and rest in moderation. Timing is medicine. The body heals in rhythm, thrives in rhythm. And so might we. This book charts a course back into flow with nature’s temporal patterns. Here lies the fruit of chronobiology – illuminating our biological heritage to live timely. Master these cycles, and transform your days. Peak performance, robust health, and deep meaning emerge from within. Come. Let us synchronize our lives anew.

Available in PDF, EPUB and Kindle. Book excerpt: Biological rhythmicity has been a subject of scientific research for a relatively short time. In the special case of daily, or circadian rhythms, it is only during the past twenty years that rapidly increasing efforts have been undertaken in evaluat ing properties and mechanisms. As a consequence of these efforts, the study of biological and, in particular, circadian rhythmicity is no longer a somewhat dubious occupation but rather a serious branch of science which combines the interdisciplinary efforts of numerous researchers around the world. The general result of these efforts is that many features of circadian rhythms of many different species of living beings are well known today. In addition to studies with lower organisms, the evaluation of human circadian rhythms was originally more or less a compulsory exercise done in order to extend the "catalogue of species"; of course, the work was of unusual impor tance due to the special position of man in biology. In the course of the very first experimental series, it became clear that humans possess an "internal clock" as had been established in various organisms, protists, plants, and animals, and that human circadian rhythms fit the general regularities of biological rhythms known at that time. However, it soon became apparent that circadian rhythmicity of man shows, additionally, particularities of great general interest, for practical and theoretical reasons.
