Inter-Session Repeatability Of Marker-Less Motion Capture Of Treadmill Running Gait, Matthew F. Moran, Isabella C. Rogler, Justin C. Wager Jan 2023

Inter-Session Repeatability Of Marker-Less Motion Capture Of Treadmill Running Gait, Matthew F. Moran, Isabella C. Rogler, Justin C. Wager

Exercise Science Faculty Publications

Twenty-one experienced runners completed three treadmill running sessions on different days. Each session consisted of three consecutive 2 min trials at self-selected speeds (RPE = 3, 5, and 7). An eight-camera marker-less motion capture system and instrumented pressure treadmill (TM) collected data over the final ~25 s at each speed. Lower extremity joint angles (ankle, knee, and hip) and segmental angles (pelvis and trunk) were computed for each trial with foot contact and toe off being kinematically determined. Spatiotemporal metrics (ground contact time, step length, and cadence) were measured via TM and compared to their kinematically derived counterparts. All spatiotemporal …

The Effects Of Accentuated Eccentric Loading On Barbell And Trap Bar Countermovement Jumps, Christopher B. Taber, Calin Butler, Victoria Dabek, Benjamin Kochan, Kyle Mccormick, Emily Petro, Timothy J. Suchomel, Justin Merrigan Jan 2023

The Effects Of Accentuated Eccentric Loading On Barbell And Trap Bar Countermovement Jumps, Christopher B. Taber, Calin Butler, Victoria Dabek, Benjamin Kochan, Kyle Mccormick, Emily Petro, Timothy J. Suchomel, Justin Merrigan

Exercise Science Faculty Publications

This study examined effects of accentuated eccentric loading (AEL) on barbell and trap bar loaded countermovement jumps (LCMJ). Twenty-one subjects (16 male, 5 female; Age: 23.5 ± 1.8 years; Body mass: 81.4 ± 10.6 kg; Height: 176.9 ± 7.2 cm; Training age: 7.1 ± 2.6 years) participated in this study. Upon establishing one repetition maximum and baseline jumping conditions, three experimental loading sessions were completed in random order. Barbell and trap bar LCMJ were performed with a spectrum of fixed loads from 20-50 kg during control conditions and with additional AEL loads of 10, 20, or 30 kg for experimental …

Drivers Of Change In Mindfulness- And Acceptance-Based Interventions With Athletes: Investigating The Influence Of Dosage, Readiness, And Attitudes, Thomas O. Minkler Jan 2023

Drivers Of Change In Mindfulness- And Acceptance-Based Interventions With Athletes: Investigating The Influence Of Dosage, Readiness, And Attitudes, Thomas O. Minkler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mindfulness- and Acceptance-based interventions (MABIs) are being used with increasing frequency with sport participants. Research suggests that such interventions may promote sport performance and impact performance-relevant factors, although the current quality and quantity of research is low. Specifically, questions about intervention engagement (i.e., dosage), potentially impacted by stage of change and attitudes toward sport psychology, need clarification. The present study utilized a multi-method, quasi-experimental longitudinal design with female- and male- identified NCAA collegiate athletes to investigate the effects of an MABI. Specifically, one NCAA Division II team (n = 16) and three NCAA Division III teams (n = …

Longitudinal Sport Science Implementation In American Collegiate Men’S Basketball, Jason Stone Jan 2023

Longitudinal Sport Science Implementation In American Collegiate Men’S Basketball, Jason Stone

Graduate Theses, Dissertations, and Problem Reports (ETD)

The expanding opportunities to implement sport science frameworks in elite-level basketball environments coincide with the sport’s increasing global prominence. Concomitant to these opportunities is the continual growth of the sport technology market (e.g., wearables, force plates) and computational power (e.g., data management tools, coding capabilities), which yields solutions and challenges for both athletes and practitioners. Due to the rapid influx of new sport technologies in high performance environments, particularly American Collegiate Men’s Basketball, more formal and ecologically valid research on how to effectively utilize data derived from them, particularly over long periods of time (i.e., multiple seasons) is needed. To …
