Addresses the theory that there is an oversupply of Ph.D. scientists in the United States. Suggests that the physiology field assess graduate training and make proposals for curriculum change. Develops viewpoint that universities probably should not significantly decrease the overall training effort but rather change curriculum to prepare students…

Examines the perceived conflict some scientists feel about the philosophy of science becoming a part of the education of scientists worldwide, including physiologists. Contends that the perceived conflict is due mainly to misunderstanding and some flawed reasoning in a few constructivist approaches, and that there is no fundamental conflict that…

Describes how school nurses can advocate for adolescent female students and help them avoid the female athlete triad that includes disordered eating, amenorrhea, and osteoporosis. The article focuses on consequences of the triad, how to uncover the symptoms, working to improve public support, and creating a successful program through partnership.…

Evaluated college women enrolled in a strength training class before and after completion of the class, using a combination of physical fitness measures, to determine the relationship between strength training and body image. Strength training generally did not substantially change participants' weight, percentage of fat, or circumferences. Most…

Reports on meta-analysis of 183 experiments comparing the effect sizes (average amount of change observed) of measurement techniques for assessing the effectiveness of public speaking anxiety treatments. Shows differences between self-report, observer, and physiological measurement techniques. Finds no interaction between type of therapy and type…

A study of 80 children, aged 7, 10, 13, and 16, found that gender was not an important variable in speech breathing, but age was. The youngest group exhibited such things as larger lung, rib cage, and abdominal volume initiations and terminations for breath groups and fewer syllables per breath group. (Author/JDD)

Adults (N=142) who engaged in a 12-week moderate exercise program requiring the maintenance of training state exercise heart rates for a minimum of 20 minutes, 3 times a week, experienced an improvement in cardiovascular functioning regardless of age and/or sex. (Author/IAH)

In terms of physical impact, recent studies suggest that many benefits previously attributed to exercise as a factor in weight loss do not exist. Researchers do seem to agree that exercise does have a positive effect on body composition during weight loss. (IAH)

Presented is a simulation program for Apple II computer which assays the effects of a series of variables on bacterial growth and interactions between microbial populations. Results of evaluation of the program with students are summarized. (CW)

Perceived exertion scales, based on subjective perception of energy output, are gaining respect as prescribing and monitoring tools for individual exercise programs. A review of recent literature indicates growing research interest in applications for individuals who are elderly, inactive, or subject to medical conditions such as angina. (IAH)

The process of a 1992 consensus conference that examined relationships among physical activity, fitness, and health variables is described. The conference involved internationally known scientists with relevant expertise. The paper discusses potential sources of physical activity, the benefits of physical activity, the possible harmful effects of…

Data on the dose-response gradient for the relation of physical activity or physical fitness to health and function are reviewed, refuting the idea that physical activity programs are either exercise for health or for fitness and suggesting that the key factor is the total energy expenditure of the activity. (SM)

Examines the effects of physical activity on depression and anxiety, discussing the scientific strength of studies on physical activity, depression, and anxiety against the standards of science accepted in epidemiology with a focus on the independence, consistency, dose-response gradient, and biological plausibility of the evidence. (Author/SM)

Introduces psychological perspectives on stress, noting conceptual models that guide sport and exercise psychology. After presenting key aspects of Lazarus' stress model, the paper reviews major lines of research related to stress within sport and exercise psychology. Lazarus suggests more information can be gained by considering emotion along…

Discusses the implications for professional practice and society of physical activity and stress, looking at the views of a series of papers that examined the issue of stress and exercise. The article focuses on what is missing in current research on stress and physical activity. (SM)
