Reviews empirical studies on aging and learning that support the thesis that learning slows down aging and some of its physical and cognitive subprocesses. (Contains 54 references.) (SK)

Tested the mastery hypothesis as an explanation for the affective benefits of acute exercise. Undergraduate women from a self-selected aerobic dance class rated their exercise performance following class. Affect questionnaires were completed before and at 5 and 20 minutes after the class. Results showed an overall improvement in affect following…

Examines data from research on stretching as it relates to enhanced performance and injury prevention so that fitness, exercise, and sports performance professionals can make informed decisions about stretching programs for clients. The paper notes that stretching is a misunderstood component of fitness and sports training. Few studies show…

Examined whether anxiety-reducing conditions of low- and moderate-intensity cycling exercise would lead to changes in emotional responsiveness to pictures designed to elicit pleasant neutral, and unpleasant emotions among healthy female college students. Results indicated that cycling exercise resulted in decreased baseline activity of facial…

Examined types and frequencies of musculoskeletal injuries among adults with above average activity levels enrolled in the Dallas Aerobics Center Longitudinal Study. Participant surveys and examinations indicated that one-quarter of all respondents reported musculoskeletal injuries (most of which were activity- related). Sport participants had the…

Because football season becomes dangerous when warm weather collides with the need for protective gear, researchers investigated critical heat balance limits in non-heat- acclimatized men who wore various football uniform ensembles and exercised at 35 percent VO2 max in a programmable environmental chamber. The air temperature and humidity limits…

Summarizes proposed variables linked with higher incidences of anterior cruciate ligament tears in females and the biomechanical aspects of the lower extremity during the performance of common basketball skills, focusing on gender differences in knee joint stability and neuromuscular control, biomechanical aspects of lower extremity skills in…

TARGET is an acronym coined to define the motivational climate influences of Task design, Authority structure, Rewards, Grouping arrangements, Evaluation practices, and Timing. This article explains the benefits of using TARGET with high school weight trainers of all body types, explaining that a mastery- oriented climate is established when the…

Electrodermal activity, peripheral blood flow, and heart rate were recorded from 19 adult stutterers and 19 normal speakers during performance of jaw movements. There were no differences between the two groups of speakers, suggesting that the stutterers did not have abnormally high levels of autonomic activation in speech. (Author/DB)

Examines the influence of hormonal factors during pregnancy on maternal responsiveness in infrahuman animals and human beings. Argues that it is likely that maternal behavior in humans has a physiological basis. (PCB)

Headaches experienced by athletes are categorized (exertional, effort, and trauma-triggered migraines), and treatment methods related. Consequences of misdiagnosis, lack of reporting, and poor monitoring are discussed as well as categories of athletes most likely to suffer sports-related headaches. (IAH)

Describes an inexpensive method of measuring energy expenditure during exercise. Presents the materials needed to conduct the experiment, basic principles, procedures, calculation and analysis, and a discussion of results. (ZWH)

This preliminary investigation of stuttering development and maturation of speech motor processes recorded the electromyographic activity of the orofacial muscles of nine children who stuttered. Results suggest that the emergence of tremor-like instabilities in the speech motor processes of stuttering children may coincide with aspects of general…

Forward-masked psychophysical tuning curves were obtained at multiple probe levels from 26 normal-hearing listeners and 24 ears of 21 hearing-impaired listeners with cochlear hearing loss. Results indicated that some cochlear hearing losses influence the sharp tuning capabilities usually associated with outer hair cell function. (Author/JDD)

Hearing loss resulting from excessive noise levels remains a concern in technology education laboratories. Teachers must take responsibility to provide a safer, less noisy environment. (SK)
