Sex-Based Differences In Concussion Outcomes Among Adolescents And Young Adults, Jacob James Michael Kay

Theses and Dissertations

Concussive injuries among youth are a serious public health concern in the United States, with increasing incidence leading the Centers for Disease Control and Prevention to classify these injuries a “silent epidemic.” Though most concussions in youth resolve within a few weeks, a significant proportion (~15-20%) of individuals will experience persisting symptoms that can negatively affect important aspects of social life, as well as academic and vocational performance. Furthermore, guidelines from the most recent Consensus Statement on Concussion in Sport highlight the importance of considering individual characteristics that may modify the nature and outcomes of concussion. Biological sex is one …

How “Dependent” Are We? A Spatiotemporal Analysis Of The Young And The Older Adult Populations In The Us, Debasree Das Gupta, David W. S. Wong

Kinesiology and Health Science Faculty Publications

The shifting of a country’s age structure has far-reaching socioeconomic and policy implications. In the US, the changing age structure at the sub-national level has received little research attention. To address this gap, we examine age dependencies across states in the US between 1990 and 2010 using decennial census data. We find that dependency changes have been gradual with a distinct graying of states during this period. Within this overarching trend, the sources of states’ dependencies follow complicated trajectories without clear spatiotemporal patterns. Nevertheless, changes in states’ old-age dependency contributions to respective total dependencies are geographically clustered and the inverse …

The Experiences Of Athletes, Parents, And Coaches With The Long-Term Athlete Development Model (Ltad) In Youth Soccer Academies, Kody Watson

Theses and Dissertations (Comprehensive)

The Long-Term Athlete Development Model (LTAD) has been developed to allow children the best chance of engaging in lifelong sport and physical activity. The LTAD focuses on long-term development, not short-term success, which allows for the best opportunity of sport participation and optimal sport potential throughout life (Balyi, Way, & Higgs, 2013). Research surrounding the LTAD model has stated that there is a lack of empirical evidence of the model being utilized within sport, as some researchers believe that it is more theoretical than practical (Lloyd & Oliver, 2012). However, even with this criticism of the LTAD model, Canadian sport …
