A Motivational Climate Intervention And Exercise-Related Outcomes: A Longitudinal Perspective, Theresa C. Brown, Mary D. Fry, E. Whitney Moore

Kinesiology, Health and Sport Studies

While researchers have suggested that the social context in exercise settings is linked to individuals’ physical activity motivation and potential exercise-related outcomes, few research designs have examined the nuance of those relationships. Moreover, interventions targeting the social context of exercise settings are sparse, so the potential impact of staff training on members’ motivation to exercise are not well known. Drawing from two major motivation theories, achievement goal perspective theory and self-determination theory, this study considered an intervention with fitness center staff from the members’ perspectives. Members completed a survey before and after an intervention designed to help staff create a …

Youth Program Adult Leader's Directive Assistance And Autonomy Support And Development Of Adolescents’ Agency Capacity, David Hansen, E. Whitney Moore, Nadia Jessop

Kinesiology, Health and Sport Studies

Developing a capacity for exercising agency is an important developmental task of adolescence. Many organized youth programs provide adolescents opportunities to build their capacity to exercise agency. The researchers tested hypotheses that adult youth program leader's directive assistance and autonomy support would promote adolescents’ capacity for agency. They surveyed 441 high school adolescents and 11 adult advisors from 10 Future Farmers of America chapters twice over 2 years. Adolescents self‐reported on their capacity for agency and advisors reported on each adolescent's capacity. Directive assistance and autonomy support correlated with the capacity for agency within both time points. Only autonomy support …

Using Yoga To Reduce Stress And Bullying Behaviors Among Urban Youth, Erin E. Centeio, Laurel Whalen, Erica Thomas, Noel Kulik, Nate Mccaughtry

Kinesiology, Health and Sport Studies

Background/Purpose: Obesity and secondary conditions continue to disproportionally affect the health of children living in urban areas. Studies show that a lack of resources and physical activity-unfriendly communities discourage 60 minutes of daily activity, including strengthening exercises, as recommended by the Centers for Disease Control and Prevention. Using Social Ecological theory, the purpose of this study was to examine the multi-level influences of a yoga-based intervention on urban, inner city youth. Method: Using a mixed-methods design, ninety-three 3 - 5^th grade students at five urban elementary schools participated in a ten-week yoga intervention. Analysis/Results: RM-ANOVA results …

Implementing Comprehensive School Physical Activity Programs: A Wayne State University Case Study, Erin E. Centeio, Nate Mccaughtry

Kinesiology, Health and Sport Studies

Comprehensive school physical activity programs (CSPAPs) have been highlighted by numerous public health and education agencies for their potential to improve the health and academic achievement of American youth. A CSPAP integrates physical activity throughout the school environment before, during and after school by engaging educators, children, families and community organizations. As the design, implementation and evaluation of effective CSPAP programs has inched forward, so has the call for physical education teacher education (PETE) programs to prepare the next generation of physical educators with the skills and knowledge needed to one day lead CSPAP efforts in K-12 schools. The purpose …

Identifying The Function Of The Calpain Small Subunit In The Mechanics Of Cell Migration, Bingqing Hao

Wayne State University Dissertations

Cell migration plays a vital role in many physiological events including: morphogenesis, wound healing, and immune response. Dysfunctional cell migration results in multiple disease states including chronic inflammation, vascular disease, and tumor metastasis, to name a few. Progress in understanding the mechanism of cell migration had been slow until the turn of the century when rapid technological advances in microscopy and omics burst to the forefront. These advances led to the realization that physical factors (dimensions, fluid shear stress, hydrostatic pressure, compression stress, environmental stiffness, and topography) have profound effects on cell migration. This study of cell mechanics has expanded …

An Investigation Of The Mechanism Of Traumatic Brain Injury Caused By Blast In The Open Field, Ke Feng

Wayne State University Dissertations

Blast-induced traumatic brain injury (bTBI) is a signature wound of modern warfare. The current incomplete understanding of its injury mechanism impedes the development of strategies for effective protection of bTBI. Despite a considerable amount of experimental animal studies focused on the evaluation of brain neurotrauma caused by blast exposure, there is very limited knowledge on the biomechanical responses of the gyrenecephalic brain subjected to primary free-field blast waves imposed in vivo, and the correlation analysis between the biomechanical responses and its injury outcomes. Such information is crucial to the development of injury criteria of bTBI.

This study aims to evaluate …

Psychosocial Predictors Of College Student Athlete Burnout And Engagement, Brigid Byrd

Wayne State University Dissertations

Purpose: The purpose of this study was to assess salient psychosocial predictors of both academic and athletic burnout and engagement in college student athletes. Method: One-hundred and seventy-nine male and female college student athletes were recruited from a Midwestern University to complete a questionnaire at one time point. Results: The prediction model for athlete burnout was statistically significant, F (4,174) = 16.41, p<.001, and accounted for approximately 27% of the variance. The prediction model for athlete engagement was also statistically significant, F (4,174) = 9.25, p ≤ .001, and accounted for approximately 18% of the variance. The prediction model for student burnout was statistically significant, F (6,172) = 3.79, p<.005, and accounted for approximately 10% of the variance. The prediction model for student engagement was not statistically significant. Conclusions: Athletes who felt misunderstood by their coach, felt their coach did not provide options and choices, and who felt their coach was not confident in their sport ability experienced symptoms of athlete burnout while athletes who felt understood by their coach, felt their coach provided options and choices, and who felt their coach had confidence in their sport ability, believed in their ability to accomplish their sport goals, felt engaged in their sport. Also, athletes who felt their coach was less friendly and supportive if they were not training and competing well, felt intimidated by their coach, and who felt their coach tried to control their free time and who also felt their teammates did not encourage them to study or did not make sure they got to class had high student burnout. Application: Coaches should aim to create an autonomy supportive coaching climate in which athletes feelings of autonomy are enhanced. Exploratory findings also suggest decreasing controlling coaching behaviors and increasing teammate academic social support may be important in thwarting feelings of student burnout in student athletes.

Biomechanics Of Concussion: The Importance Of Neck Tension, Ron Jadischke

Wayne State University Dissertations

Linear and angular velocity and acceleration of the head are typically correlated to concussion. Despite improvements in helmet performance to reduce accelerations, a corresponding reduction in the incidence of concussion has not occurred (National Football League [NFL] 1996 – present).

There is compelling research that forces on and deformation to the brain stem are related to concussion. The brain stem is the center of control for respiration, blood pressure and heart rate and is the root of most cranial nerves. Injury to the brain stem is consistent with most symptoms of concussion reported in the National Football League and the …

Development Of A Finite Element Pelvis And Lower Extremity Model With Growth Plates For Pediatric Pedestrian Protection, Ming Shen

Wayne State University Dissertations

Finite element (FE) model is a useful tool frequently used for investigating the injury mechanisms and designing protection countermeasures. At present, no 10 years old (YO) pedestrian FE model has been developed from appropriate anthropometries and validated against limitedly available impact response data. A 10 YO child FE pelvis and lower extremities (PLEX) model was established to fill the gap of lacking such models in this age group. The baseline model was validated against available pediatric postmortem human subjects (PMHS) test data and additional scaled adult data, then the PLEX model was integrated to build a whole-body FE model representing …

Biofidelity Assessment Of 6-Year-Old Anthropometric Test Devices (Atds) And Scaling Laws In Lateral Impact, Jennifer Yaek

Wayne State University Dissertations

There is a clear need to further develop the design and biofidelity of the 6-Year-Old ATDs for future child safety research and child occupant protection in side impacts. Due to the scarcity of pediatric PMHS impact testing, specifically in the lateral direction, alternative means of obtaining relevant data for pediatric models need to be considered.

In this first portion of this study, assessment of the mechanical behavior and biofidelity of existing 6-Year-Old ATDs in lateral impact were performed. None of the three 6-year-old ATDs (HIII, Q6, and Q6s) tested were found to be considered good tools for assessing side impact …

National Franchise Members’ Perceptions Of The Exercise Psychosocial Environment, Ownership, & Satisfaction, E. Whitney G. Moore, Mary D. Fry

Kinesiology, Health and Sport Studies

The purpose of this study was to examine the relationship between: a) the motivational climate developed by a national exercise franchise and b) members’ sense of ownership in and enjoyment of exercise. Members of a national exercise franchise (N=5,329) were surveyed to learn their views on the motivational climate (autonomy supportive, caring, task- and ego-involving), exercise class ownership, and class enjoyment. Mean scale scores revealed this national exercise franchise succeeded in developing a high caring (M = 4.60 ± .68), task-involving (M = 4.04 ± .62), and autonomy supportive (M = 5.98 ± 1.00) climate, and low ego-involving (M = …
