Physical inactivity is a major risk factor for developing coronary artery disease. It also increases the risk of stroke and such other major cardiovascular risk factors as obesity, high blood pressure, low HDL ("good") cholesterol and diabetes. The American Heart Association recommends that children and adolescents participate in at least 60 minutes of moderate to vigorous physical activity every day. Increased physical activity has been associated with an increased life expectancy and decreased risk of cardiovascular disease. Physical activity produces overall physical, psychological and social benefits. Inactive children are likely to become inactive adults. This book presents new research in the field from around the world.
The IXth International World Symposium on Biomechanics and Medicine in Swimming was held in Saint-Etienne in France from June 21 - 23 2002, under the auspices of the World Commission of Sport Biomechanics and the Steering Group of Biomechanics and Medicine in Swimming. The main conference organisers were the Laboratoire de Physiologie of the Medical Faculty and Service d'Exploration Fonctionnelle Cardio-Respiratoire et Médecine du Sport of Saint-Etienne Hospital. The conference was a joint effort with several other organisations as well. The Department of Physical Education of the University of Saint-Etienne, the City of Saint-Etienne, the Conseil Général de la Loire, the Conseil régional Rhône-Alpes, the Association des Chercheurs en Activités Physiques et Sportives, the French Swimming Federation, the INSERM, the Ministry of Foreign Affairs, the Société de la Loire de Médecine du Sport and the société française de Médecine du Sport were the main public sponsors of the Symposium.
Explores the fundamental processes of motor learning and skill acquisition in sport. This book examines the interaction of personal, environmental and task-specific constraints in the development of motor skills, and demonstrates how an understanding of those constraints can be applied in a wide range of specific sports and physical activities.
Cellular life depends upon energy storage, transformation, utilization, and exchange in order to optimally function and to stay-off death. The over 200-year-old study of how cells transform biological fuels into usable energy, a process broadly known as bioenergetics, has produced celebrated traditions in explaining origins of life, metabolism, ecological adaptation, homeostasis, biosynthesis, aging, disease, and numerous other life processes. InTech's edited volume, Bioenergetics, brings together some of these traditions for readers through a collection of chapters written by international authorities. Novice and expert will find this book bridges scientific revolutions in organismic biology, membrane physiology, and molecular biology to advance the discipline of bioenergetics toward solving contemporary and future problems in metabolic diseases, life transitions and longevity, and performance optimization.
Triathlon is among the world's most gear-intensive sports. The gear you select and how you use it can mean big results--or bigger disappointment. FASTER takes a scientific look at triathlon to see what truly makes you faster--and busts the myths and doublespeak that waste your money and race times. In this fascinating exploration of the forces at play in the swim-bike-run sport, astronautical engineer and triathlete Jim Gourley shows where to find free speed, speed on a budget, and the gear upgrades that are worth it. FASTER offers specific, science-based guidance on the fastest techniques and the most effective gear, answering questions like: Which wetsuit is best for me? What's the best wa...
Pour chaque thème, il détaille les connaissances théoriques fondamentales avec l'aide de schémas synthétique pour en faciliter la compréhension. En s'appuyant sur ses connaissances, il propose des solutions concrètes pou une transposition cohérente et efficace sur le terrain. Après avoir rappelé le rôle de l'entraîneur et détaillé les bases fondamentales de l'entraînement, proposé une méthode pratique permettant de transposer sur un plan pratique les principes théoriques de la physiologie de l'activité musculaire, il développe les approches techniques d'apprentissage, propose différents entraînements spécifiques, des méthodologies, des organisations et une planification adaptée aux objectifs et aux niveaux des nageurs. Une dernière partie totalement novatrice propose une préparation mentale simple et facile à mettre en œuvre afin d'anticiper les problèmes que peuvent rencontrer les nageurs.
Since 1991, the edited book series Studies in Perception and Action has appeared in conjunction with the biennial International Conference of Perception and Action (ICPA). ICPA provides a forum for researchers and academics who share a common interest in ecological psychology to come together, present new research, and foster ideas towards the advancement of the field. This volume highlights research presented at the 17th ICPA meeting in the summer of 2013. The short papers and empirical articles presented in this book represent the contributions of researchers and laboratories from across the globe. The reader will find new, cutting-edge research on a wide variety of topics in perception and action. This volume will especially appeal to those that are interested in James J. Gibson's ecological approach to psychology, as well as, more broadly, students and researchers of visual and haptic perception, perceptual development, human movement dynamics, human factors, and social processes.
