Assessing Physical Activity Determinants In Urban Settings: Comparison Of Perceptions And Environmental Audit Findings, Daniel Remley, Susan Zies, Beth Stefura, Ryan Leone, Kendra Kattelmann, Tandalayo Kidd

Health and Nutritional Sciences Faculty Publications

Sedentary lifestyles are a contributor to obesity and urban adolescents are less physically active than rural adolescents. Supportive physical activity environments, understood as the geography, observations, and perceptions of features such as recreational facilities, sidewalks, bike lanes, traffic patterns, etc., have been positively associated with adolescent physical activity behaviors within urban settings. As part of a Socio-Ecological intervention to improve physical activity behavior, the Physical Activity Resource Assessment (PARA), the Active Neighborhood Checklist (ANC), and focus groups were used to assess the physical activity influences within an urban middle school and surrounding community. The assessments suggested that lack of parks, …

A Qualitative Analysis Of Barriers To And Facilitators Of Successful Weight Loss, Alyson Drooger

Background: Along with the United States obesity epidemic comes extensive weight loss attempts. One way people are attempting to lose weight is through meal replacement programs. Much work has been done to study strategies of structured weight loss programs and examine their success. Limited work has been done to study the specific barriers and facilitators of the real life participants who join weight loss programs. The purpose of this study is to identify, through qualitative research methods, the barriers to and facilitators of weight loss while participating in a meal replacement program.

Methods: Twenty-nine members of a meal replacement program …

The Effect Of Six Days Of Dietary Nitrate Supplementation On Performance In Trained Crossfit Athletes, Samuel J. Kramer, Daniel A. Baur, Maria T. Spicer, Matthew D. Vukovich

Health and Nutritional Sciences Faculty Publications

Background: While it is well established that dietary nitrate reduces the metabolic cost of exercise, recent evidence suggests this effect is maintained 24 h following the final nitrate dose when plasma nitrite levels have returned to baseline. In addition, acute dietary nitrate was recently reported to enhance peak power production. Our purpose was to examine whether chronic dietary nitrate supplementation enhanced peak power 24 h following the final dose and if this impacted performance in a heavily power-dependent sport.
Methods: In a double-blind, randomized, crossover design, maximal aerobic capacity, body composition, strength, maximal power (30 s Wingate), endurance (2 km …

Differences In Running Mechanics Between Overweight/Obese And Healthy Weight Children, Kristen Roles

Electronic Theses and Dissertations

Background/Purpose: Physical activity is commonly prescribed to reduce childhood obesity. However, due to differences in mechanics during low-impact activities, such as walking, obese children may be more prone to negative physical complications during high-impact activities, such as running. Therefore, this study analyzed the mechanical differences in running mechanics between healthy weight (HW) and overweight/obese (OV/OB) children. We hypothesized that when compared to HW children, OV/OB children would display higher vertical loading, greater joint moments and greater joint angular impulses during running. We also expect decreased sagittal plane range of motion and increased frontal plane range of motion of the hip, …
