Examining Correlations With Frequency Of Walking Trips In Metropolitan Areas, Michelle J. Marcus

Public Health Theses

This research assessed correlations between funding for pedestrian facilities, presence of walkways, and daily and weekly walking trips in a sample of United States residents living in metropolitan areas. The purpose of the research was to identify factors at the policy and environmental level which are associated with a greater frequency of walking trips, and therefore may influence physical activity levels. Data from the U.S. Federal Highway Administration’s 2001 National Household Travel Survey and the Thunderhead Alliance’s 2007 Benchmarking Report: Bicycling and Walking in the U.S. were combined to provide variables for the number of daily and weekly walking trips, …

Exploratory Study Of Environmental Effects On Physical Activity And Overweight In Older Women: Research Update, Heather A. Whitcomb, Kosuke Tamura, Lauren Milius, Francine Laden, Steve Melly, Peter James, Robin Puett, Ellen Cromley, Eran Ben-Joseph, Philip J. Troped

GIS Day

Background: Physical inactivity and obesity are major public health issues. Recent studies have provided evidence that attributes of the built environment influence physical activity among adults and that factors such as greater urban sprawl are related to overweight and obesity. Few studies have developed objective individual-level measures of the built environment, a geographic scale that may be more relevant to certain types of physical activity, such as walking. In addition, further research is needed to assess the associations of both objective and perceived environmental factors with physical activity. In this 2-year exploratory study funded by the National Cancer Institute, we …

Acute Exercise Protects Against Doxorubucin Cardiotoxicity, Karen Y. Wonders, David S. Hydock, Carole M. Schneider, Reid Hayward

School of Sport & Exercise Science Faculty Publications

Numerous methods have been used to minimize the cardiotoxic effects of the chemotherapeutic agent doxorubicin (DOX), and most have had limited success. Chronic endurance exercise has been shown to protect against DOX cardiotoxicity, but little is known regarding the effects of acute exercise on DOX-induced cardiac dysfunction. Purpose. The purpose of this study was to determine the effects of a single bout of acute endurance exercise on the cardiac dysfunction associated with DOX treatment. Methods. Male Sprague-Dawley rats either performed an acute exercise bout on a motorized treadmill for 60 minutes at a maximal speed of 25 m/min with a …

The Influence Of Preferred Attentional Focus Strategies On Exercise Induced Changes In Affect, Erin L. Heltsley

Masters Theses & Specialist Projects

Along with the numerous physical benefits of exercise, past research has shown that physical activity can alleviate symptoms of anxiety and depression in both clinical and non-clinical populations. Yet, it has been suggested less than half of American adults exercise at public health recommended levels. Therefore, it is important to identify factors that may lead to an increase in physical activity and, subsequently, improvements in mental health. Previous research, for the most part, has neglected to investigate how preference for attentional focus strategy during exercise influences mood. In addition, previous studies that involved attentional focus and exercise have focused more …

Obesity Risk Knowledge, Self-Efficacy, And Physical Activity In Families Of Adolescents, Elaine M. Rutkowski Phd, Msn, Rn, Cns

Dissertations

There were no significant relationships found between parental obesity risk knowledge and physical activity in their children. nor between parent's self efficacy and their children's physical activity. In addition there was no significant relationship between the adolescents' obesity risk knowledge and their physical activity. There was, however, a statistically significant relationship between adolescent's self efficacy and physical activity. The result of the correlation between parent's self-efficacy and their level of physical activity was not significant but approached significance (p = .07) and may be identified as a trend. There was a statistically significant negative correlation between parents who describe their …

Health Sciences Papers and Journal Articles

Background: Different approaches to measuring physical activity and fatness in youth have resulted in studies reporting relationships ranging from very strong to non-existent.

Methods: The sample comprised 787 males and 752 females aged between 7 and 16 years. Pedometer-determined physical activity, height, weight and waist girth measures were taken.

Results: Significant differences were found in activity level between BMI-determined weight categories for the females (F(1, 742) = 9.07, p = .003) but not for the males (F(1, 777) = 3.59, p = .06) and between truncal adiposity groupings for both the males (F(1, 777) = 4.69, p = .03) and …

Encouraging Physical Activity In Teens. Can Technology Help Reduce Barriers To Physical Activity In Adolescent Girls?, Tammy Toscos Phd, Anne Faber, Kay Connelly, Adity Mutsuddi Upoma

Health Services and Informatics Research

Physical activity levels of girls decline dramatically during adolescence and may be a contributor to the increasing number of obese teens in the United States. Research has shown that social support is positively correlated with physical activity levels in adolescents, particularly girls. We present the findings from a three week field study of a mobile phone application designed to create a support group for physical activity within an existing social network of adolescent girls. Our findings suggest design considerations for technologies that encourage physical activity for this user group.

Presented at 2008 Second International Conference on Pervasive Computing Technologies for …

The Effectiveness Of Mentoring-Based Professional Development On Physical Education Teachers' Pedometer And Computer Efficacy And Anxiety, Jeffrey J. Martin, Nate Mccaughtry, Pamela Hodges Kulinna, Donetta Cothran, Roberta Faust

Kinesiology, Health and Sport Studies

The purpose of our study was to examine the impact of mentoring-based professional development on physical education teachers' efficacy. Experienced mentor teachers were paired (n = 15) with inexperienced protégé teachers (n = 15) at the beginning of a yearlong intervention study. It was hypothesized that teachers would increase their efficacy to use pedometers and computers to enhance instruction, and reduce their computer anxiety. Repeated-measures ANOVAs for mentors and protégés revealed a variety of significant main effects. We found increases in computer and pedometer efficacy. A second set of repeated-measures ANOVAs based on mentors', protégés', and control groups' …

Physical Activity And Blood Pressure In Childhood: Findings From A Population-Based Study, Sam D. Leary, Andy R. Ness, George Davey Smith, Calum Mattocks, Kevin Deere, Steven N. Blair, Chris J. Riddoch

Faculty Publications

The pathological processes associated with development of cardiovascular disease begin early in life. For example, elevated blood pressure (BP) can be seen in childhood and tracks into adulthood. The relationship between physical activity (PA) and BP in adults is well-established, but findings in children have been inconsistent, with few studies measuring PA mechanically. Children aged 11 to 12 years were recruited from the Avon Longitudinal Study of Parents and Children. 5505 had systolic and diastolic BP measurements, plus valid (at least 10 hours for at least 3 days) accelerometer measures of PA; total PA recorded as average counts per minute …
