The International Symposium on Biomechanics and Medicine in Swimming, held every four years under the aegis of the International Society of Biomechanics and the World Commission of Sports Biomechanics, provides a forum in which research related to swimming is reported and problems that confront swimming practitioners are debated. This volume contains the papers presented at the sixth symposium. The keynote addresses covered lactate metabolism, performance determining factors and the analysis of sprint swimming. The contributed papers range widely across sports science, coaching and training and sports medicine.

This book contains edited and revised papers presented at the VIth International Symposium on Biomechanics and Medicine in Swimming. Held under the auspices of the International Society of Biomechanics and the World Commission of Sports Biomechanics, this multi-disciplinary symposium was attended by delegates from 30 countries, emphasizing the international interest in this subject. The contributions highlight the wealth of quality research being undertaken in the field of swimming throughout the world. Three keynote papers are included: "Lactate Metabolism for Swimming", "Performance Determining Factors in Front Crawl Swimming", and "Analysis of Sprint Swimming". The main contents are then grouped into nine sections, organized by discipline: biomechanics, electromyography, swim technique, training, lactate metabolism, performance and physiology, medical considerations, kinanthropometry, and psychological factors. This comprehensive book presents recent research but also tackles some of the current problems facing swimming practitioners. It aims to be a review for researchers in swimming, lecturers and students on sports science and physical education courses and sports medics and

Why am I always tired? Why can't I sleep at night? Why do I suffer from jetlag?

We all have a body clock, a biological structure that controls how we feel, our mental and physical performance, and whether we are active or asleep. This is nature's response to our rhythmic environment, dominated by day and night. Though the body clock normally adjusts us to daytime activity and night time sleep, it can go wrong or be tricked by lifestyle changes. This can result in jetlag, some forms of insomnia and even depression. Keeping in time with your body clock provides clear and accessible advice on how to live with, and not against, your body clock. In a clear and accessible style, it explains how the body clock works, how and why it can work against you, and the measures you can take to optimise your feeling of health and wellbeing. It also explains the role of the body clock in illness, and how an understanding of this can increase your feeling of health.

An essential book for anyone who wants to better understand their body and optimise their feeling of health and wellbeing.

The effects of circadian rhythms on human performance in general and on response to exercise in particular are a well-known phenomenon. Often after a poor night's sleep or taking a "red-eye" flight into a different time-zone, one just doesn't feel like "themselves." This book aims to provide a comprehensive account of biological rhythms and how they affect exercise. Particular attention is given to sleep, its biological function, and the consequences for exercise performance of sleep loss. There are chapters devoted to the effects of disturbing the circadian body clock, such as when multiple time zones are crossed and jet-lag experienced. The effects of nocturnal shift work and seasonal variation are also covered. The interactions between exercise and the female menstrual cycle are explained and the issue of exercise during pregnancy discussed. Finally, there is a chapter devoted to research methods in chronobiology, the scientific discipline underpinning the content of the book.
