Metabolic and cardiovascular responses during 45 minutes of continuous moderate intensity exercise were investigated in 11 children, 8-11 years of age. Results indicate that children exhibit metabolic and cardiovascular adjustments similar to those noted in adults during prolonged exercise. (Author/JMK)

A physically more active life, while not being related to atherosclerosis, could enable some individuals to live longer with atherosclerosis before dying from or showing symptoms of coronary heart disease. (MJB)

Healthy hematologic adaptations to exercise are described. The benefits of increased performance for elite athletes and reduced risk of heart attack for the general population are stressed. The advisability of increased amounts of fish in the diet and low doses of aspirin to reduce coronary risk factors are discussed. (Author/MT)

These fact sheets focus on exercising for improved physical fitness. Answers to common questions about exercise are presented. An outline is provided on two exercise programs--walking and jogging. A discussion is presented on how to start an exercise program. A chart provides information on heart rates for different ages and the length of exercise…

A panel of eight experts discuss the cardiovascular, lipoprotein, weight control, and psychological benefits of exercise on health. The challenge of motivating people to exercise regularly is explored. (Author/MT)

Eight young adult males with Down syndrome received a 16-week rowing ergometry training regimen. Following training, no changes in cardiovascular fitness were found but participants did achieve significantly higher levels of work performance on both treadmill and rowing ergometer tests than did a control group. (Contains references.) (Author/DB)

This study investigated the question of hemoconcentration-hemodilution and subsequent vascular fluid shifts evidenced by marathon runners. Blood samples were taken from runners before and after the New York City Marathon of 1978 and the Fiesta Bowl Marathon of the same year. Participants were of both sexes. Tables accompanying this report present…

Current knowledge in the area of muscle physiology is a basis for a discussion on strength training programs. It is now recognized that the expression of strength is related to, but not dependent upon, the size of the muscle and is probably more related to the ability to recruit more muscle fibers in the contraction, or to better synchronize their…

Patients with chronic conditions such as coronary artery disease, hypertension, diabetes, and obesity might benefit from prescribed exercise. Although exercise does not reverse pathologic changes, it may play a role in disease management. (JD)

A primary goal of the cardiovascular evaluation of exercisers is to identify conditions that carry the risk of exercise-related sudden death. These conditions, which are found in a careful evaluation of the patient, are identifed and described in detail. (Author/JL)

The effects of passive exercise of the extremities on peripheral vision of muscular dystrophic children aged 9 to 13 years was investigated. Compared to control subjects, those who experienced six minutes of passive exercise evidenced increased peripheral vision. Curriculum revisions for muscular dystrophic children indicate the importance of…

Findings from a survey of 92 American medical school curriculums suggest that physicians may be unprepared to offer effective counseling on exercise. The survey showed that 67 percent of schools had no formal instruction in exercise medicine. A required course emphasizing cardiorespiratory fitness is recommended. (IAH)

Emphasizing cardiovascular fitness may be a barrier to mobilizing the sedentary individual. Instead, encouraging low-level physical activity may be an effective first step. Beliefs held toward cardiovascular fitness are presented, and ways in which these beliefs may present barriers to adoption of any level of physical activity are discussed. (IAH)

Reviews possible mechanisms by which exercise lowers blood pressure and discusses research which indicates exercise is an effective therapy for hypertension. The article presents information to help physicians counsel hypertensive patients wanting to start an exercise program and examines the use of exercise testing to predict the onset of…

This paper presents information on the effectiveness of exercise programs for heart attack victims. Some of the observations come from unpublished results of a two year experiment of the National Exercise and Heart Disease Project. The paper first establishes that a group exercise program with trained supervision is advantageous for people with…
