An Interpretative Phenomenological Analysis Of Black Female Swimmers' Experiences Of Belonging, Felicity E. Passon
Master's Theses
Although swimming participation has grown in the United States, the experiences of Black female swimmers remain significantly underrepresented in academic literature. This study addresses that gap by exploring the lived experiences of Black women participating in Division 1 (D1) college swimming. Using Interpretative Phenomenological Analysis (IPA) and Black feminist thought, the research explored how Black female D1 swimmers experienced belonging in this underrepresented sport. Semi-structured interviews were conducted with nine D1 Black female swimmers, and six major themes illustrate the varied factors that shaped their experiences of belonging. Even with racially gendered barriers to inclusion, they identified strategies to foster …

Objectives
Movement behaviors, such as sedentary behavior (SB), light intensity physical activity (LPA), and moderate to vigorous intensity physical activity (MVPA) are mutually exclusive, in that time spent in one behavior inevitably displaces time spent in another. Yet, few studies have simultaneously considered these health behaviors and their association with health-related quality of life (HRQoL), an important indicator of health and well-being in aging populations. This study aimed to explore the role of waking movement behaviors (i.e., SB, LPA, MVPA) in prospectively predicting HRQoL in older adults. The study further aimed to cross-validate associations between movement behaviors and HRQoL using …

Background
Optimizing human performance under stressful physical and cognitive conditions is paramount during high-stakes military operations. As such, interventions to improve warfighter performance by mitigating task-induced cognitive performance deficits are necessary. While caffeine is the most widely consumed psychoactive substance in the world, common side effects (i.e. anxiousness, micro-saccades, irritability) may be detrimental to warfighter operations. Theacrine, a purine alkaloid similar in structure to caffeine but with a longer half-life, less habituation, and fewer side effects, is proposed as a caffeine-alternative to enhance cognitive resilience.

Children's ambulatory sleep is commonly measured via actigraphy. However, traditional actigraphy measured sleep (e.g., Sadeh algorithm) struggles to predict wake (i.e., specificity, values typically < 70) and cannot predict sleep stages. Long short-term memory (LSTM) is a machine learning algorithm that may address these deficiencies. This study evaluated the agreement of LSTM sleep estimates from actigraphy and heartrate (HR) data with polysomnography (PSG). Children (N = 238, 5–12 years,52.8% male, 50% Black 31.9% White) participated in an overnight laboratory polysomnography. Participants were referred be-cause of suspected sleep disruptions. Children wore an ActiGraph GT9X accelerometer and two of three consumer wearables(i.e., Apple Watch Series 7, Fitbit Sense, Garmin Vivoactive 4) on their non-dominant wrist during the polysomnogram. LSTM estimated sleep versus wake and sleep stage (wake, not-REM, REM) using raw actigraphy and HR data for each 30-s epoch. Logistic regression and random forest were also estimated as a benchmark for performance with which to compare the LSTM results. A 10-fold cross-validation technique was employed, and confusion matrices were constructed. Sensitivity and specificity were calculated to assess the agreement between research-grade and consumer wearables with the criterion polysomnography. For sleep versus wake classification, LSTM outperformed logistic regression and random forest with accuracy ranging from 94.1to 95.1, sensitivity ranging from 94.9 to 95.9 across different devices, and specificity ranging from 84.5 to 89.6. The addition of HR improved the prediction of sleep stages but not binary sleep versus wake. LSTM is promising for predicting sleep and sleep staging from actigraphy data, and HR may improve sleep stage prediction.

Ergonomic And Biomechanical Assessment Of Vertical Ladder Climbing For Exoskeleton Integration In Construction Tasks, Ehsan Shourangiz
LSU Master's Theses
Active exoskeletons are increasingly utilized in physically demanding industries such as construction and manufacturing to reduce strain and lower the risk of work-related musculoskeletal disorders, supporting worker safety and long-term health. However, most existing systems are designed for repetitive tasks like lifting or prolonged standing, with limited consideration for dynamic activities such as vertical ladder climbing. Ladder climbing is common and physically demanding in industrial environments, often required to access elevated areas like scaffolding, tanks, or rooftops. Since exoskeletons are intended to remain worn throughout multiple tasks, requiring workers to remove and re-don the device during ladder climbing would reduce …

Background: High-intensity functional training (HIFT) varies daily workout programming, and trainees are often tasked with completing “as many repetitions as possible” (AMRAP) within a set time. Successful performance depends on fatigue management skills and maintaining a consistent expression of force and velocity when performing and transitioning between exercises over the duration of the workout. Multi-ingredient preworkout (MIPS) supplement formulations often contain ingredients shown to facilitate energy availability and mitigate fatigue, and therefore, might positively affect HIFT performance. This study aimed to assess a multi-ingredient pre-workout supplement’s acute effect on pacing and the expression of kinetics throughout a 5- and 15-minute …

The connection between sport and morality is a key focus of J. S. Russell’s scholarly work. He rejects the ‘separation thesis’, which claims that sport has a significant degree of autonomy and thus its own set of values separate from those of society. Instead, he supports the ‘continuity thesis,’ which suggests that the moral values at the heart of sport reflect more basic moral values found outside its boundaries. Therefore, for Russell, individuals involved in sport do not leave ordinary morality to enter a separate sporting one. Rather, they engage in a social practice whose core moral principles are extensions …

Topics in Exercise Science and Kinesiology
Topics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 9, 2025. Exercise-induced hypoalgesia (EIH) is a transient decrease in pain perception that can be observed following various tasks, including low-intensity and high-intensity exercise. The application of blood flow occlusion (BFO) can help enhance exercise adaptations while being able to exercise at a low intensity, which has important implications for clinical and rehabilitative settings. Through descending inhibitory pathways, BFO-induced pain can potentially alleviate exercise-induced pain. This study aimed to assess whether the superimposition of BFO – and its associated augmented perceived responses – during low-intensity, low-volume resistance exercise could …
