Human Movement Studies & Special Education Faculty Publications

Over the eight years from 2015 to 2023, the Ultimate Fighting Championship (UFC) partnered with the United States Anti-Doping Agency (USADA) to institute comprehensive external oversight of doping controls. This study investigates the effects of transitioning from internally administered anti-doping protocols to exclusive external governance by comparing UFC performance metrics before and during the USADA partnership. Using a Difference-in-Differences (DiD) approach with data from 2012 to 2018, we find that match duration significantly increased, while the likelihood of extreme outcomes, knockouts (KO), technical knockouts (TKO), and submissions, decreased during the USADA period. These results suggest that performance-enhancing drugs (PEDs) could …

Relationships Between Quadriceps Neuromuscular Function And Time From Surgery Following Acl Reconstruction Are Sex-Specific, Tatiana Restrepo

Honors Undergraduate Theses

Anterior cruciate ligament reconstruction (ACLR) is associated with persistent quadriceps dysfunction, including muscular weakness and altered spinal and cortical excitability. While recovery has been widely studied, most investigations focus on isolated domains and fixed postoperative time points. Emerging evidence suggests females often experience slower or less complete quadriceps recovery compared to males, yet the time-dependent nature of these sex-specific outcomes remains unclear. The purpose of this study is to examine whether relationships between time since ACLR and quadriceps neuromuscular outcomes differ by sex across muscular, spinal, and cortical domains. Adults aged 18–35 with a history of primary, unilateral ACLR were …

Stability Of Salivary Microrna Measures Across An Ncaa Division I Football Season: Implications For Microrna As A Biomarker Of Concussion, Thomas R. Campbell, Martina Zamponi, Delaney Leathers, Julie Cavallario, Jessica C. Martinez, Peter A. Mollica

Rehabilitation Sciences Faculty Publications

Background

Clinicians often face challenges in concussion care due to a heavy reliance on subjective patient input. Recently, research has sought objective biomarkers, like salivary microRNAs, to improve concussion management. However, significant limitations hinder the use of microRNAs as a diagnostic tool, including the cumulative effects of a contact sport season. A better understanding of the response to a contact sport season would help researchers and clinicians interpret expression changes at the time of injury in the context of seasonal variation. in Therefore, this study investigated the reliability of previously identified salivary microRNA targets across one contact sport season.
