A method for testing oxygen uptake while subjects are swimming is described and analyzed. (JD)

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…

A review of previous research was completed to determine (a) the response of the cardiac time components of the left ventricle to varying types and intensities of training programs, (b) the probable physiological explanations for these responses, and (c) the significance of the changes which did or did not occur. It was found that, at rest,…

A pulmonary function ratio describing oxygen extraction from alveolar ventilation was used for an intergroup comparison between three groups of athletes (rugby, basketball, and football players) and one group of sedentary subjects during steady-state submaximal exercise. The ratio and its component parts are determined from only three gas…

The purpose of this study was to compare the coronary heart disease (CHD) probability estimates of a group of sedentary males involved in an exercise stress test program from 1968 through 1974 with those of a comparison group of sedentary males not involved in the program. The program was designed to evaluate cardiopulmonary function and improve…

This investigation studied the physiological profiles of eight highly trained female dance majors. To be considered highly trained, each subject had to be dancing a minimum of three hours a day, four to five days a week, for the last year. They also had to meet the criterion of dancing at least ten hours a week for the last five years prior to…

To evaluate the effects of drinking glucose and fructose before prolonged exercise, six female runners were given glucose, fructose, saccharin, or plain water to drink before running to exhaustion. Metabolic processes were monitored. The best performance came from those drinking water alone. Fructose seemed preferable to glucose, however.…

In an attempt to identify physiological factors that account for success in distance running, researchers evaluated relationships among ventilatory threshold, running economy, and distance running performance. Subjects were trained male runners with similar maximal aerobic power. (Authors/PP)

Oxygen uptake and heart rate kinetics for submaximum exercise (bicycle riding) were compared in prepubescent boys and adult men. Resulting data suggest that children and adults do not differ significantly in cardiorespiratory adjustments during low-intensity exercise. (Authors/PP)

This is a report on research in the field of physical responses of children to strenuous activity. The paper is divided into three subtopics: (1) peak performance measure in children; (2) training effects on children; and (3) importance of physical activity for children. Measurements used are oxygen consumption, ventilation, heart rate, cardiac…

A major concern to practitioners in the wellness movement has been the dearth of high quality up-to-date information about their field. This book provides a comprehensive and current look at the wellness field. Presentations in part 1 include: (1) "The History and Future of the Wellness Movement" (Donald B. Ardell); (2) "Presenting…

An abundance of research relative to physical fitness and, more generally, physical education of school children, has surfaced during the past few years. Negative aspects of health and physical fitness are increasing year by year, and further evidence suggests that academic performance is negatively affected by low levels of fitness. A survey was…
