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.

Benefits Of Exercise Intervention In Reducing Neuropathic Pain, John L. Dobson, James L. Mcmillan, Li Li

Health Sciences & Kinesiology: Faculty Publications

Peripheral neuropathy is a widespread and potentially incapacitating pathological condition that encompasses more than 100 different forms and manifestations of nerve damage. The diverse pathogenesis of peripheral neuropathy affects autonomic, motor and/or sensory neurons, and the symptoms that typify the condition are abnormal cutaneous sensation, muscle dysfunction and, most notably, chronic pain. Chronic neuropathic pain is difficult to treat and is often characterized by either exaggerated responses to painful stimuli (hyperalgesia) or pain resulting from stimuli that would not normally provoke pain (allodynia). The objective of this review is to provide an overview of some pathways associated with the development …

The Perceived Demands Of Crossfit, Bryanne N. Bellovary

All NMU Master's Theses

Rhabdomyolysis is the breakdown of muscle tissue causing myoglobin, creatine kinase, and other intracellular proteins and electrolytes to leak into circulation, disrupting cell homeostasis. Exertional rhabdomyolysis (ER) occurs after extremely rigorous physical training that could include high amounts of strenuous eccentric exercise. There has been an increase in reports for mild to severe ER as well as other musculoskeletal injuries as the popularity of extreme conditioning programs (e.g., CrossFit®) increases. Therefore, the main purposes of this investigation were to identify: primary risk factors associated with ER during CrossFit®, CrossFit® workouts that might induce a higher risk for the development of …

Amputation Effects On The Underlying Complexity Within Transtibial Amputee Ankle Motion, Shane R. Wurdeman, Sara A. Myers, Nikolaos Stergiou

Journal Articles

The presence of chaos in walking is considered to provide a stable, yet adaptable means for locomotion. This study examined whether lower limb amputation and subsequent prosthetic rehabilitation resulted in a loss of complexity in amputee gait. Twenty-eight individuals with transtibial amputation participated in a 6 week, randomized cross-over design study in which they underwent a 3 week adaptation period to two separate prostheses. One prosthesis was deemed “more appropriate” and the other “less appropriate” based on matching/mismatching activity levels of the person and the prosthesis. Subjects performed a treadmill walking trial at self-selected walking speed at multiple points of …

Effects Of Graston Technique On Blood Flow In The Upper Extremity, Ashley Nicole Keck

Theses and Dissertations

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. …
