Summarizes results from the Olympic Exercise Asthma Summit Conference, offering the latest on identifying and managing exercise-induced asthma (EIA). Concludes that effective pharmacologic and nonpharmacologic treatment is available, but EIA is underrecognized and underdiagnosed. Physicians should look for it in all patients, including school…

Describes a course that uses student-designed laboratory experiments for a one-semester, junior-level physiology course. Discusses advantages and pitfalls of using this methodology. (Author/KHR)

Tested the hypothesis that physical training (PT), especially high-intensity PT, would favorably affect components of the insulin resistance syndrome (IRS) in obese adolescents. Data on teens randomized into lifestyle education (LSE) alone, LSE plus moderate -intensity PT, and LSE plus high-intensity PT indicated that PT, especially high-intensity…

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)

High school coaches and athletic trainers should know proper first aid techniques, have special knowledge about particular sports injuries, have a good understanding of safety precautions for playing equipment and skill techniques, and understand environmental factors that may affect athletes. (JD)

Described are animals that can filter their food out of the water. Various structures modified to strain plankton and small animals from water are detailed. The adaptive significance of these structures is discussed. (CW)

Described is the discovery that oscillations of electric potential at 40 hertz hold the key to how the brain assembles sense impressions into a single object. Potential implications from this research are discussed. (CW)

Describes circadian timekeeping which matches internal states with environmental changes, and the ultradian clock which coordinates intracellular processes including energy cycles, protein turnover, and cell division. Presents discussions of biological rhythms and its characteristics. (RT)

Attitudes toward physical activity among 564 undergraduate and graduate students were primarily influenced by gender, year in school, activity class enrollment, and the passage of time. An experimental group, which received mini-lectures on the scientific bases of exercise, showed little significant change in attitude. The survey instrument is…

The training phase of a rehabilitation program for football players who have sustained lower back injuries proceeds after the pain-control phase, and seeks to minimize risk of reinjury. This phase emphasizes movement training and exercise for strengthening abdominal muscles to stabilize the lumbar spine. A removable exercise guide is included.…

This article discusses the relevance of fitness programing for an aging population and provides parameters for a geriatric fitness program. Emphasized are physical activity as a preventive measure against age-related illness and management of a geriatric fitness program. (IAH)

Summarizes and critiques 16 studies involving the cognitive and behavioral effects of aerobic exercise on children in both schools and clinical settings. Concludes that few studies concurrently measure physical and psychological changes that may accompany exercise in children and suggests methods for further investigation. (SW)

Presents case study of first congenitally deaf British infant to receive multichannel cochlear implant. Used video analysis of achievement of audio objectives to detail pre- and postimplantation phases. Results demonstrated the importance of gesture in transition to written language; benefit of early identification, amplification, and referral for…

Describes activities in which high school students exercise individual muscles or small groups of muscles to try to determine which muscles are involved, their approximate origins, and insertions. (MKR)

Reviews theory and methods used by the field of biological psychology to study stress that have potential for understanding how behavioral and biological adaptations to the stress of exercise are integrated. The overview focuses on anxiety, depression, and physiological responsiveness to nonexercise stressors from the perspective of biological…
