Compared the energy cost of treadmill walking in pairs of obese and lean adolescent boys matched for total body mass. Results found no intergroup differences in the net energy cost at the two lower speeds, but obese boys expended more energy at a higher speed. Heart rate was considerably higher in obese boys. Body mass, rather than adiposity, was…

Reports on a simple classroom exercise that investigates whether students' beliefs of what they think should happen influences their measurements. The exercise also provides a framework for discussing the challenges that human belief systems bring to the discipline of using the scientific process. Results suggest that students' preconceived…

Presents a lab that can be offered after students have learned the basic anatomy and physiology of the various phyla, the primary objective of which is to explore and apply their acquired knowledge to a new situation. Involves exploring the anatomy and life-style of the squid. (JRH)

Briefly discusses the work of physician and physical educator Delphine Hanna, examining the philosophy of medicine and explaining how physical education, kinesiology, and sport and exercise science in the United States are all rooted in medical tradition. The paper also discusses the subjective and objective understanding of human body movement.…

Examined the physiological responses of elderly Japanese women to a well-rounded exercise program performed in water. Results indicated that the 12-week program elicited significant improvements in intervention group women's cardiorespiratory fitness, muscular strength, agility, flexibility, body fat, and total cholesterol. Water-based exercise…

This report presents nonexperimental retrospective data on the weights, menstrual cycle intervals, pregnancy symptoms, and running programs of two women who exercised intensely during their first two trimesters. Although these two cases suggest that strenuous anaerobic exercise during pregnancy is not harmful, more studies are needed. (IAH)

A new analysis, based on the concept of the ideal observer in signal detection theory, is described. It allows: tracing of the flow of discrimination information through the initial physiological stages of visual processing for arbitrary spatio-chromatic stimuli, and measurement of the information content of said visual stimuli.

Investigates the preservation of inhibited and uninhibited behaviors in 100 children of 14, 20, 32, and 48 months. Children who had been extremely inhibited or uninhibited at 14 and 20 months differed significantly at 4 years of age in behavior and cardiac acceleration. (RJC)

This article summarizes the current knowledge on the effects of beta-adrenergic blocking drugs, used widely for treatment of cardiovascular diseases, on exercise performance, training benefits, and exercise prescription. (IAH)

As more and more patients survive a coronary event, the need for cardiac rehabilitation will increase. The author reviews the history and current status of this field and predicts what lies ahead. (JD)

Comparison of the physiological responses to an induced cognitive stressor of 30 gifted junior high schools students and their nongifted peers found the skin temperature change to be significantly less in the gifted sample and recovery time to be considerably faster. (Author/DB)

This article reviews auditory deprivation effects on anatomy, physiology, and behavior in animals and discusses the sequelae of otitis media with effusion (OME) in children. Focused on are central auditory processing disorders associated with early fluctuating hearing loss from OME. (DB)

A survey of middle-aged physicians, runners and nonrunners, indicated that the runners had lower body weight and reduced cardiovascular risk factors, and that they smoked fewer cigarettes. (JD)

The ILO92 was used to determine the level of Distortion Product Otoacoustic Emissions (DPOAEs) at 2f1-f2 for 16 combinations of primary levels in the range of 40 to 80 dB SPL from 40 unimpaired adult ears. An overall increase of DPOAE amplitude with increase in primary level was observed. (Author/CR)
