Low Energy Availability, Disordered Eating, Exercise Dependence, Injury Prevalence, And Fueling Habits In Female Crossfit® Participants, Alyssum Reno-Smith

Dissertations

Disordered eating (DE) is primarily observed in endurance athletes and sports with aesthetics emphases. The prevalence of DE in resistance trained individuals, particularly CrossFit^®, is not well understood. CrossFit® promotes a culture encouraging strong, athletic, or muscular bodies, and both CrossFit® and endurance athletes aim to achieve a low body fat percentage to improve performance. This may lead to body dissatisfaction, exercise dependence (EXD), and/or DE behaviors, which may contribute to Relative Energy Deficiency in Sport (REDs). This cross-sectional study investigated DE prevalence and relationship with EXD risk, body dissatisfaction, and fueling habits in female CrossFit® only (CO) …

Returning To Physical Activity Following Injury: Exploring Psychological Readiness In Middle-Aged Adults, Hunter Martin

Theses and Dissertations (Comprehensive)

Previous researchers have focused on a variety of psychological aspects of injury rehabilitation in the context of returning to competitive sport (Ardern et al., 2016; Donald, 2019; Podlog et al., 2022; Webster et al., 2018). Return to sport decisions have been largely based on physical assessment and functional ability tests with little focus on psychological elements of recovery (Podlog et al., 2015). The existing literature on psychological readiness (PR) to return to sport has grown in recent years, primarily exploring the experiences of young adult athletes aged 18-30 (Podlog et al., 2022).

Modulation Of Persistent Inward Currents With Changes In Posture And Cutaneous Sensory Input, Ryan William Weller

Theses and Dissertations (Comprehensive)

Spinal motor neuron (MN) persistent inward currents (PIC) increase and sustain the MN output. PIC is amplified by descending monoamines and reduced by afferent inhibition. There is strong coupling between plantar cutaneous sensory input and lower limb MNs. Given that monoaminergic drive is altered with postures and motor tasks, our purpose was to assess posture-dependent plantar cutaneous sensory modulation of tibialis anterior (TA) MNs. We hypothesize that: 1) a supine position will suppress PIC, 2) removing the load from the bottom of the heel will inflate PIC, and 3) cutaneous stimulation of the plantar aspect of the heel will reduce …
