Problems with Temperature Regulation during Exercise covers the proceedings of the 1976 Problems of Temperature Regulation during Exercise symposium in conjunction with the American College of Sports Medicine meeting, held in Anaheim, California. This book contains seven chapters that consider the various aspects of a specialized problem within the broader area of temperature regulation and exercise physiology. After briefly providing an overview of the temperature regulation during exercise, this text goes on discussing the physical means by which heat is transferred both within the body and between the body and its environment. These topics are followed by a presentation of the physiological systems that control the rates of heat transfer. The subsequent chapters examine the conditions in which the controlling systems are limited in their abilities to transfer heat and to adapt in their capabilities. The remaining chapters explore the specific influences that enhance heat dissipation mechanisms at a given level of central thermoregulatory drive. This work is of great benefit to circulatory physiologists and biophysicists.

The physiology of man is a complex subject. Unfortunately the regulation of temperature in the human body is not always well explained in textbooks. Many conference proceedings on the subject have been produced that give excellent detail on research topics. However, the subject matter is rarely presented as a composite whole. New technology has broadened the scope of methods available for studying body temperature. Thermography in particular has made it possible to record in real time the temperature distribution of large areas of the body surface. Modem image processing methods permit dynamic studies to be carried out and detailed analyses made retrospectively-a tremendous advance over the complex and slow techniques formerly used by physiologists. Yet although the associa tion between disease and temperature is as old as medicine itself, beyond the implicit faith in the clinical mercury thermometer, other measuring techniques are finding a slow acceptance. This book is designed to put into perspective the critical factors that make up "body temperature. " Body temperature cannot be viewed as a static entity but rather must be seen as a dynamic process. An understanding of this phenomenon is important to all who use thermal imaging and measuring techniques in clinical medi cine. These methods have, in recent years, brought engineers, physi cists, technicians, and clinicians together. Inevitably, however, there v vi Preface are gaps and overlaps in technology and understanding.

Should scientific congresses take place in connection with Olympic Games, and should science be represented not only in the form of applied science engaged in the care of athletes, but also as an informing, reflecting and critical authority? The Organizing Committee for the Games of the XXth Olympiad answered this question in the affirmative, and the results have justified this decision. The invitation sent out by the Organizing Committee was accepted by numerous eminent scholars and many participants from all over the world; it was their merit that the general topic of the congress could be discussed in manifold ways under various aspects and without prejudice. For this reason, they deserve our gratitude and appreciation. By now, the congress report has been completed. It is part of the total scientific concept which includes the preparatory publication, "The Scientific View of Sport Perspectives, Aspects, Issues", the congress itself and the present report; and, in close connection therewith, the exhibitions, "100 Years of German Excavation Work in Olympia", "Sport and Medicine" and the literary exhibition. It is to be hoped that this report will prove an important source of information and a stimulus for discussion among participants and scholars, students, teachers and coaches; and that it will safeguard the fruitful continuation of the work initiated by the Munich congress. Thanks are due to those who took pains in preparing this document. It will be an essential element within the framework of all that will remain of the Olympic Games of 1972.

Focusing primarily on the distribution of blood flow and its regulation in humans, this well-illustrated study illuminates the overall control of the human cardiovascular system. Combined for the first time in a single volume are discussions of how peripheral vascular beds are controlled in humans, how these control mechanisms interact with those of cardiac performance and the central circulation, and how this vasomotor regulation serves the whole organism, especially under condition of stress. The author also redresses an imbalance found in contemporary cardiovasculary physiology, where the "cardio" is often emphasized at the expense of the "vascular." Rowell stresses the importance of the passive properties of the venous system and argues that the human cardiovascular system has unique properties and strategies for the distribution of blood flow that are rarely observed in other species, a view that will attract attention and stimulate discussion among cardiovascular experts.

Human body temperature is regulated by a proportionate control system. It is nuclear however, which internal body temperature is regulated by the control of the thermoregulatory effector responses of skin blood flow and sweating. The core temperature increases during exercise as a result of a 'load error' and not a change in the regulated set-point temperature. During exercise the magnitude of core temperature elevation at steady-state is proportional to the metabolic rate and is largely independent of the environmental condition. However, dependent upon the environmental conditions the relative contributions of sensible (radiative and convective) and insensible (evaporative) heat exchange to the total heat loss will vary. The hotter the environment the greater the dependence on insensible heat loss. During exercise in the heat, the primary problem is to simultaneously provide the cardiovascular support to maintain the metabolism for skeletal muscle contraction and to dissipate the associated heat release. In hot environments, the core to skin temperature gradient is reduced to skin blood flow needs to be relatively high (compared to cooler environments) to achieve heat transfer sufficient for thermal balance. In addition, sweat secretion can result in a reduced plasma (by dehydration) and thus blood volume. Both high skin blood flow and reduced plasma volume can reduce cardiac filling and perhaps cardiac output during exercise in the heat. As a result syncope or reduced exercise performance will occur.
