Participant perceptions of exercise programs for overweight women

Eighteen women participated in a research project involving two phases: (a) an interview regarding weight history and exercise patterns, and (b) a series of exercise sessions followed by discussions of participants' reactions to them. The data were analyzed using inductive analysis techniques, and results of the analysis were discussed with participants for collaborative validation of the interpretation. Profiles of selected participants and themes that emerged are described. The participants varied in age and body size and had diverse backgrounds, interests, and abilities, but their shared experience of social disapproval based on body size was shown to affect their perceptions of exercise programs and their decisions about participation.     

Chemicals,Exercise and Hyperactivity: A Short Report

PSYCHOACTIVE DRUGS have been shown to enhance children's short‐term performance on a number of cognitive and social interaction measures and there are encouraging indications that physical exertion can mimic these effects. Although the health benefits of aerobic exercise have been acknowledged for some time, other parameters of physical exertion are less well‐known, particularly in the domain of human cognition. The data presented, and briefly reviewed, are supportive of the hypothesis that physical activity can enhance problem‐solving performance and for so‐called hyperactive children, their ability to attend to the task at hand. Indeed, aerobic exercise may offer an alternative to traditional chemical treatments.     

Medical student, resident, and faculty use of a computerized literature searching system

The experiences of medical students, residents, and faculty with a computerized literature searching system were evaluated. Third-year medical students, internal medicine and family practice residents, and full-time and voluntary faculty at one medical school had the opportunity to use a full-text and bibliographic medical literature retrieval system free of charge for an eleven-month period. Subjects conducted nearly nine thousand literature searches over a period of 942 system hours. Questionnaire data showed that participants could learn to use and would use an electronic information system, felt capable of using the system, utilized the system for a variety of purposes and in a number of different ways, and viewed the system as a valuable tool in searching the medical literature. The results are discussed in the context of the educational needs of the four user-groups and medical education planning by institutions.
