Environmental Correlates Of Physical Activity Among African-American Adults, Tim Bungum, Jennifer Pharr, Paulo S. Pinheiro, Maria Azzarelli

Nevada Journal of Public Health

The purpose of this cross-sectional study was to identify perceived environmental correlates of meeting physical activity guidelines among African-American adults living in Southern Nevada. Trained interviewers phoned potential participants who lived in the 12 zip codes of Clark County, Nevada with the highest proportions of African-American residents. Respondents (n=237) answered 52 health-related and demographic questions. Slightly less than 50% of participants met physical activity guidelines. A factor analysis procedure produced two environmental variables, neighborhood safety and environmental supports for physical activity. Age, gender and educational attainment (p<.05) predicted the meeting of those guidelines (R2=.214), while neighborhood support for physical activity, neighborhood safety, and BMI failed to do so. This finding suggests that environmental factors are not strong predictors of physical activity among African- American adults, although environmental supports for physical activity approached significance. Future studies should consider assessing additional aspects of the built environment as an influence on physical activity.

Persistent Fluctuations In Stride Intervals Under Fractal Auditory Stimulation, Vivien Marmelat, Kjerstin Torre, Peter J. Beek, Andreas Daffertshofer

Journal Articles

Stride sequences of healthy gait are characterized by persistent long-range correlations, which become anti-persistent in the presence of an isochronous metronome. The latter phenomenon is of particular interest because auditory cueing is generally considered to reduce stride variability and may hence be beneficial for stabilizing gait. Complex systems tend to match their correlation structure when synchronizing. In gait training, can one capitalize on this tendency by using a fractal metronome rather than an isochronous one? We examined whether auditory cues with fractal variations in inter-beat intervals yield similar fractal inter-stride interval variability as isochronous auditory cueing in two complementary experiments. …

Learning To Play: A “Hedgehog Concept” For Physical Education, Tyler Johnson

Kinesiology Faculty Publications and Presentations

What is physical education and why does it exist? Despite its relatively long and storied history, consensus about physical education’s existence remains minimal. According to Jim Collins, author of the best-selling book Good to Great, organizations or groups of professionals should determine a “hedgehog concept” or a primary reason for their existence. This article explores three questions developed by Collins to help organizations identify a hedgehog concept: (a) what are we deeply passionate about? (b) what can we be the best in the world at? and/or what can we not be the best in the world at? and (c) what …
