Many interventions have begun to focus on conveniently performed lifestyle PA, such as walking. The purpose of this study was to investigate the relationship between neighborhood safety and attractiveness and PA in a sample of African American (AA) and Hispanic or Latina (HL) women participating in Health Is Power (1R01CA109403). Method: Women (AA N=202 and HL N=107) who enrolled in the study were middle-aged (M=45.8 years), overweight (M …

Obesity And Physical Activity Variance By Income And Ethnicity In Kansas City, Katie M. Heinrich, Ws Carlos Poston, Nui Jitnarin, Anthony Randles, Joseph Hughey, Laverne Berkel, C Keith Haddock

International Journal of Exercise Science: Conference Proceedings

Purpose: Although obesity and physical activity prevalence systematically vary by income and ethnicity, it is unclear how well census data represent actual conditions. Using data from the Kansas City Built Environment and Health Study, we examined whether differences in measured obesity prevalence and self-reported physical activity would systematically vary by both census block group median income and percent ethnic minority and self-reported income and ethnicity. Methods: Participants included 586 adults; average age 45±14.7. Most participants were female (69.8%), married (51.5%), had some college or more (72.7%) and had incomes ≤$60,000 (54.6%). Households were solicited from 21 census block groups, stratified …

Reduced Knee Extensor Function In Heart Failure Is Not Explained By Inactivity, Michael J. Toth, Anthony O. Shaw, Mark S. Miller, Peter Vanburen, Martin M. Lewinter, David W. Maughan, Philip A. Ades

Mark S. Miller

Background—The goal of this study was to determine if heart failure alters knee extensor muscle torque, power production or contractile velocity. Methods—Heart failure patients (n=11; 70.4 ± 4.3 yrs) and controls (n=11; 70.3 ± 3.4 yrs) matched for age and sex were evaluated for knee extensor contractile performance under isometric and isokinetic conditions and body composition by dual energy x-ray absorptiometry. Additionally, we recruited sedentary to minimally active elderly controls to match heart failure patients for habitual physical activity and assessed activity levels using accelerometry. Results—Groups did not differ for total or regional body composition or average daily physical activity …

The Effect Of Resistance Training On Strength And Total Physical Activity In Postpartum Females, Tiffany Kaye Hinman

Theses and Dissertations

The purpose of this study was to compare strength and physical activity (PA) changes in postpartum women randomly assigned to either a four-month progressive resistance training (RT) program or a four month flexibility program. Sixty healthy women between six weeks and eight months postpartum initiated the study and 43 completed the entire study. The women tended to be overweight, were all non-smokers, and most were breastfeeding (97%) at the beginning of the study. Both groups (RT and flexibility) completed training exercises twice weekly. Both groups improved in all measures of strength (RT group: leg press, P < 0.001; bench press, P < 0.001; curl-ups, P < 0.001. Flexibility group: leg press, P = 0.009; bench press, P < 0.001; curl-ups, P = 0.005); however, the RT group had higher strength gains compared to the flexibility group over time (leg press, P < 0.005; bench press, P < 0.001; curl-ups, P < 0.007). In addition, both groups increased in low back flexibility but the group*period interaction did not reach significance (P = 0.096). Light-intensity PA increased in the RT group but not the flexibility group (P < 0.05). A group*period interaction was significant for light-intensity PA time (P = 0.031) and borderline significant for sedentary time (P = 0.054). However, controlling for the number of months postpartum and weight gain during the previous pregnancy resulted in a significant interaction for sedentary time (P < 0.05). No changes were found in moderate, vigorous, or moderate to vigorous PA within or between groups over time. In conclusion, twice-weekly RT increases strength and is associated with improvements in several PA outcomes in postpartum women; however, the mechanisms for this are unclear. The training sessions and/or increased spontaneous activity may have contributed.

Factors Affecting Bone Mineral Density In Elite Female Runners, Maureen E. Cartoon

Nutrition Theses

Introduction: The benefits of regular exercise on skeletal health have been well-documented in terms of stimulation of bone accrual and bone maintenance. Medium-impact sports activities such as running have been demonstrated to exert site-specific enhancement of bone mass in the lower appendicular skeleton. However, elite female runners engaged in high intensity training and sports activity may also be at risk of amenorrhea and low bone mineral density (BMD) resulting from inadequate caloric intake. Purpose: To investigate the effect of intensive exercise and maintenance of adequate caloric intake on BMD in a group of elite female runners. Methods: This study represents …

The Impact Of A Pilot Community Intervention On Health-Related Fitness Measures In Overweight Children, Jenny G. Hutchens, Jennifer L. Caputo, Janet M. Colson, Richard S. Farley, Matthew S. Renfrow, Eric P. Seguin

International Journal of Exercise Science

The purpose of this study was to pilot a 5-week community-based intervention on improving measures of health-related fitness in overweight children. Data were obtained from 8 overweight and obese 8- to 14-year-old children. Measurements included muscular fitness (curl-ups and modified pull-ups), aerobic capacity (20 meter progressive aerobic cardiovascular endurance run [PACER] test), body composition (tricep and calf skinfolds), body mass index (BMI), and flexibility (back saver sit-and-reach). A significant reduction in BMI was observed at post-test compared to baseline (p = .03). There was a significant decrease in body fat at post-test for boys (p = .013).

Methods—Participants n = 116, 18–73y, mean BMI = 26.1) walked at self-selected slow, medium, and fast speeds around an indoor circular hallway (0.47km). Both activity monitors were attached to a belt secured to the hip and simultaneously collected data in 60 second epochs. To compare differences between monitors, the average difference (bias) in count output and steps output were computed at each speed. Time spent in different activity intensities (light, moderate, vigorous) based on the Freedson et al. cut-points was compared for each …

Measured And Self-Reported Neighborhood Characteristics And Physical Activity Among African American Women, Kristen M. Mcalexander, Rebecca E. Lee, Scherezade K. Mama, Ashley V. Medina

International Journal of Exercise Science: Conference Proceedings

African American women are vulnerable to physical inactivity compared to white women. Measured and self-reported neighborhood characteristics may be associated with physical activity (PA), yet few studies have examined these factors among minority women. The purpose of this study was to investigate the associations of measured and self-reported neighborhood characteristics with individual PA. The Pedestrian Environment Data Scan was completed for 25% of randomly selected residential street segments within a 400 meter radius of each participants’ address. African American women (N=262, M age=44.4 yrs) completed interviewer administered questionnaires assessing self-reported neighborhood characteristics. PA was measured using the International Physical Activity …

Endurance Exercise Training Effects On Body Fatness, Vo2max Hdl-C Subfractions, And Glucose Tolerance Are Influenced By A Plin Haplotype In Older Caucasians, Nathan T. Jenkins, Jennifer A. Mckenzie, Coleen M. Damcott, Sarah Witkowski, James M. Hagberg

Exercise and Sport Studies: Faculty Publications

Perilipins are lipid droplet-coating proteins that regulate intracellular lipolysis in adipocytes. A haplotype of two perilipin gene (PLIN) single nucleotide polymorphisms, 13041A>G and 14995A>>T, has been previously associated with obesity risk. Furthermore, the available data indicate that this association may be modified by sex. We hypothesized that this haplotype would associate with body fatness, aerobic fitness, and a number of cardiovascular (CV) risk factor phenotypes before and after a 6-mo endurance exercise training program in sedentary older Caucasians. The major haplotype group (13041A/14995A; n = 57) had significantly lower body mass index (BMI) and body fatness compared with …

"A"-Kids: Activity Kcal Intervention Daily Study. Effects Of 100-Kcal Daily Energy Expenditure On Total Moderate-To-Vigorous Physical Activity In 3rd Grade Children, Cheryl A. Howe

Open Access Dissertations

A selection of common children’s games were measured in a laboratory-based study to be enjoyable and to elicit sufficient physical activity energy expenditure (PAEE) in 3rd grade children to combat the purported chronic energy surplus of childhood obesity (~100 kcal.day-1). PAEE during the games was similar for boys and girls, yet overweight children expended greater PAEE relative to body weight than healthy weight children. During a subsequent simulated recess program, the enjoyment declined over the 10-session program with no significant decline in PAEE. Using the enjoyable games of known energy cost in a structured recess program for 9 weeks successfully …

Pregnancy: A "Teachable Moment" For Weight Control And Obesity Prevention, Suzanne Phelan

Kinesiology and Public Health

Excessive gestational weight gain has been shown to relate to high-postpartum weight retention and the development of overweight and obesity later in life. Because many women are concerned about the health of their babies during pregnancy and are in frequent contact with their healthcare providers, pregnancy may be an especially powerful "teachable moment" for the promotion of healthy eating and physical activity behaviors among women. Initial research suggests that helping women gain the recommended amount during pregnancy through healthy eating and physical activity could make a major contribution to the prevention of postpartum weight retention. However, more randomized controlled trials …
