TL;DR: Understanding the stages of exercise behavior could yield important information for enhancing rates of participation in physical activity in the study of exercise.
Abstract: The stages of change model has shown promise in advancing knowledge about smoking behavior change and other negative addictive behaviors The model was applied to the study of exercise, a healthy rather than unhealthy behavior A stages of exercise behavior questionnaire was administered to a sample of 235 employees Next, the ability of a second questionnaire measuring physical activity behavior to differentiate employees according to stage of exercise was tested Results revealed that 51% of employees were participating in no physical activity (Precontemplation, Contemplatation) and 49% were participating in occasional or regular physical activity (Preparation, Action, Maintenance) Scores on physical activity behavior items significantly differentiated employees among the stages This model developed on smoking and other behaviors can be generalized to exercise behavior Understanding the stages of exercise behavior could yield important information for enhancing rates of participation in physical activity

TL;DR: These guidelines are a revision of the 1995 standards of the AHA that addressed the issues of exercise testing and training and current issues of practical importance in the clinical use of these standards are considered.
Abstract: The purpose of this report is to provide revised standards and guidelines for the exercise testing and training of individuals who are free from clinical manifestations of cardiovascular disease and those with known cardiovascular disease. These guidelines are intended for physicians, nurses, exercise physiologists, specialists, technologists, and other healthcare professionals involved in exercise testing and training of these populations. This report is in accord with the “Statement on Exercise” published by the American Heart Association (AHA).1
These guidelines are a revision of the 1995 standards of the AHA that addressed the issues of exercise testing and training.2 An update of background, scientific rationale, and selected references is provided, and current issues of practical importance in the clinical use of these standards are considered. These guidelines are in accord with the American College of Cardiology (ACC)/AHA Guidelines for Exercise Testing.3
### The Cardiovascular Response to Exercise
Exercise, a common physiological stress, can elicit cardiovascular abnormalities that are not present at rest, and it can be used to determine the adequacy of cardiac function. Because exercise is only one of many stresses to which humans can be exposed, it is more appropriate to call an exercise test exactly that and not a “stress test.” This is particularly relevant considering the increased use of nonexercise stress tests.
### Types of Exercise
Three types of muscular contraction or exercise can be applied as a stress to the cardiovascular system: isometric (static), isotonic (dynamic or locomotory), and resistance (a combination of isometric and isotonic).4,5 Isotonic exercise, which is defined as a muscular contraction resulting in movement, primarily provides a volume load to the left ventricle, and the response is proportional to the size of the working muscle mass and the intensity of exercise. Isometric exercise is defined as a muscular contraction without movement (eg, handgrip) and imposes greater pressure than volume …

TL;DR: Changing the focus to basic behavioral and social science and mediator change research should provide a more systematic and cost-effective approach to increasing the effectiveness of physical activity interventions.

TL;DR: The paper outlines the research evidence, focusing on the relation between physical exercise and depression, anxiety, stress responsivity, mood state, self esteem, premenstrual syndrome, and body image.
Abstract: The relation between physical exercise and psychological health has increasingly come under the spotlight over recent years. While the message emanating from physiological research has extolled the general advantages of exercise in terms of physical health, the equivalent psychological literature has revealed a more complex relation. The paper outlines the research evidence, focusing on the relation between physical exercise and depression, anxiety, stress responsivity, mood state, self esteem, premenstrual syndrome, and body image. Consideration is also given to the phenomena of exercise addiction and withdrawal, and implications for exercise prescription are discussed.

TL;DR: In this article, the authors applied the model of the stages and processes of change to exercise adoption and maintenance, and found that the underlying constructs derived from smoking cessation and other addictive behaviors can be generalized to exercise behavior.
Abstract: We applied the model of the stages and processes of change to exercise adoption and maintenance. This model has shown promise in advancing theory and treatment of the addictions and other negative health behaviors, but there have been few systematic attempts to apply the model to positive health behaviors, such as exercise adoption. Questionnaires dealing with the stages and processes of exercise change were developed and administered to a sample of 1,172 participants in a worksite health promotion project. The sample was split randomly into halves for (a) initial model development and testing and (b) confirmatory measurement model testing. Additional model confirmation was obtained by examining the hierarchical structure of the processes of change and by conducting Stage x Process analyses. Results suggest that the underlying constructs derived from smoking cessation and other addictive behaviors can be generalized to exercise behavior. Understanding the stages and processes of exercise behavior change may yield important information for enhancing exercise adoption, adherence, and relapse prevention at both individual and public health levels.
