Towards A “Rescue Ready” Mindset: Can Lifeguard Teams Learn Lessons From The Attributes Of Chronic Unease?, Billy Rj Doyle, Jonathon Webber

International Journal of Aquatic Research and Education

Highly Reliable Organisations (HROs) are safety-centric organisations that operate in complex environments alongside risky technologies and processes. There is a high risk of catastrophe and error in these settings, the consequences of which may result in loss of life, financial cost, and damage to the environment. “Chronic unease” is a concept originally adopted by Royal Dutch Shell describing a mindset that has five predictable attributes that contribute to an individual’s and organisational safety culture. The authors of this paper describe the attributes of chronic unease in the context of lifeguard operations. A case study of a dangerous and dynamic rescue …

Wheelchair Propulsion For Everyday Manual Wheelchair Users: Repetition Training And Machine Learning-Based Monitoring, Pin-Wei Chen

Arts & Sciences Electronic Theses and Dissertations

Upper limb pain and injuries are prevalent among manual wheelchair users and can restrict their participation and daily activities. Due to the high repetition and force in wheelchair propulsion, chronic wheelchair propulsion has been linked to the risk of upper limb pain and injury. Prevention of upper limb pain and injury is a high priority in wheelchair-related research. Decades of research in wheelchair propulsion biomechanics have led to clinical practice guidelines (CPG). Unfortunately, a decade after the publication of the CPG, CPG-recommended propulsion is still uncommon. Hence, for the first aim, a randomized controlled trial pilot study with two groups …

Structural And Tissue-Level Adaptations Of Lumbar Intervertebral Discs In Humans With Inducible Low Back Pain Symptoms, Christian Isaiah Weber

McKelvey School of Engineering Theses & Dissertations

Low back pain (LBP) is a devastating musculoskeletal ailment that impacts majority of the global population. Up to 95% of cases are considered nonspecific where the origin is unclear. Although there is a diagnosis with these cases, there lacks specificity that would help individuals with treatment and pain management. Imaging techniques such as magnetic resonance imaging (MRI) are primarily utilized in the diagnosis of LBP as it illuminates internal structures of the spine. One important structure clearly identified with MRI is the intervertebral disc (IVD) that is susceptible to injury and disease. Further, diagnostic imaging is performed lying down where …

Maternal Digital Media Use During Infant Feeding And The Quality Of Feeding Interactions, Alison K. Ventura, Jordyn Levy, Sierra Sheeper

Kinesiology and Public Health

Experimental research with parents of older children suggests parents’ engagement with technological devices (e.g., television, mobile devices) in the presence of their children decreases the quality of parent-child interactions. Many mothers report frequent use of technological devices during infant feeding but, to date, few studies have explored the potential association between maternal technological device use during feeding and the quality of infant feeding interactions. To this end, mothers (n = 25) and their infants (mean age = 19.3 ± 6.4 weeks) participated in a within-subject, experimental study to explore associations between maternal digital media use and feeding interaction quality …

Ulnar Collateral Ligament Reconstruction With Traditional Docking Compared To Novel Surgical Techniques, Kayley D. Guy, Brendon P. Mcdermott, Kaitlin Gallagher, Tyrone Washington

Health, Human Performance and Recreation Undergraduate Honors Theses

Background: Ulnar Collateral Ligament Reconstruction (UCLR) is a surgical procedure on one of the main ligaments that provides normal stability for the elbow joint against excessive valgus stress. Damage to this ligament is common in athletes performing overhead throwing activities, primarily baseball players, due to excessive valgus stress during the throwing motion. The most common form of treatment for this type of injury is reconstructive surgery of the ligament, especially if athletes wish to return to sport participation. This type of surgery is extremely invasive and requires extensive post-operative rehabilitation in order to facilitate return to play. To date, many …

The Effects Of Caffeine Ingestion On The Hemostatic Response To Simulated Firefighting Activities, Sierra Wassell

Showcase of Graduate Student Scholarship and Creative Activities

The leading cause of death among firefighters is sudden cardiac event, and it is acknowledged that most ischemic events are due to an occlusive thrombus formation. In addition, due to the demanding job requirements and shift work, firefighters are commonly known to overuse caffeine as an ergogenic aid. The purposes of this study were to examine the potential effects of caffeine on the hemostatic response to simulated firefighting activity.

The Effect Of Oral Contraceptives On Caffeine Metabolism And Cycling Performance, Annette M. Lemanski

Showcase of Graduate Student Scholarship and Creative Activities

This project objectives were to determine the effects of oral contraceptives and menstrual cycle on the benefits of caffeine supplementation for cycling performance. Seventeen recreationally trained female cyclists completed four trials consisting of 3 kilometer time trials. Subjects ingested either caffeine or a placebo one hour prior to each trial. The magnitude of the ergogenic aid of caffeine was compared between oral contraceptive users and eumenorreheic females. In addition, the effect of caffeine was compared across different phases of the menstrual cycle, specifically the follicular and luteal phases.

Crises In The Aquatic Profession, Robert Keig Stallman

International Journal of Aquatic Research and Education

In this paper, I propose there are several crises in the aquatic profession and I explain what they are and how to address them using research and my own observations. I use an innovative questioning process to do this by asking you the reader a series of questions after which I explain each. The first crisis has to do with the quantity of trained swimming instructors relative to the population that they serve. In many western European and North American high income countries (HICs), the teacher:student ratios are declining and it is getting increasingly difficult to hire trained swim instructors. …

Grace Walton, Cory M. Dungan, Douglas E. Long, S. Craig Tuggle, Kate Kosmac, Bailey D. Peck, Heather M. Bush, Alejandro G. Villasante Tezanos, Gerald Mcgwin, Samuel T. Windham, Fernando Ovalle, Marcas M. Bamman, Philip A. Kern, Charlotte A. Peterson

Center for Muscle Biology Faculty Publications

Progressive resistance exercise training (PRT) is the most effective known intervention for combating aging skeletal muscle atrophy. However, the hypertrophic response to PRT is variable, and this may be due to muscle inflammation susceptibility. Metformin reduces inflammation, so we hypothesized that metformin would augment the muscle response to PRT in healthy women and men aged 65 and older. In a randomized, double-blind trial, participants received 1,700 mg/day metformin (N = 46) or placebo (N = 48) throughout the study, and all subjects performed 14 weeks of supervised PRT. Although responses to PRT varied, placebo gained more lean body …
