Water Safety Education Programs In Culturally And Linguistically Diverse Seattle Communities: Program Design And Pilot Evaluation, William A. Koon, Elizabeth Bennett, Sarah Stempski, Jennifer Blitvich

International Journal of Aquatic Research and Education

Drowning is a public health concern that disproportionally affects children and minorities in Washington State. Community health educators from Seattle Children’s Hospital designed a Water Safety Education and Lifejacket Giveaway Program for low-income parents of preschool-aged children from culturally and linguistically diverse backgrounds. The program was interpreted into multiple languages and parents and children in attendance received free lifejackets. The mixed-methods pilot evaluation of this program found statistically significant relationships between language and self-reported parent swim skill level (English-speaker OR 4.6; 95%CI: 1.84 – 11.54); and confidence of keeping one’s child safe (English-speaker OR 3.34; 95%CI: 1.10 – 10.4). Additionally, …

Surfboard Paddling Technique And Neuromechanical Control: A Narrative Review, Wynand Volschenk, Zachary J. Crowley-Mchattan, John W. Whitting, Rudi A. Meir, Alec K. Mckenzie

International Journal of Aquatic Research and Education

Surfboard paddling is an essential activity when surfing. Research investigating surfboard paddling, especially as it pertains to neuromechanical control and techniques used, is limited. Previous research made use of swim ergometers to examine surfboard paddling demands. The validity of using swim ergometers in surfboard paddling research and training deserves further analysis. To establish ecologically valid findings, researchers have begun to use swim flumes and still-water paddling environments to investigate paddling efficiency and technique. This emerging body of research has reported that muscle activation patterns, intensities, and timings differ as surfers move through different paddle stroke phases. A deeper understanding of …

Biomechanical Properties Of Land Based And Shallow Water Wait: A Comparative Review Of Literature, Mostafa Yaghoubi, Philip Fink, Wyatt H. Page, Sarah P. Shultz

International Journal of Aquatic Research and Education

Aquatic locomotion exercises are frequently used in rehabilitation and cross-training for land-based athletes. Hydrostatic pressure, thermal conductivity and drag force affect a person's ability to move; therefore, it is important to understand differences of biomechanical gait in water vs land. This review investigated biomechanical differences between shallow water and land-based exercises. PubMed, Google Scholar, SPORTDiscus and Scopus were searched; 33 studies included walking forward (27), backward (6) and running (6). Electromyographic amplitude was similar or less in submaximal intensity during aquatic gait, in comparison to on land. At maximal intensities, however, the amplitude was similar (n=5) or higher (n=4) in …

Advising Physiology Students: Perceptions From The Programs, Anne R. Crecelius, Patrick L. Crosswhite

Health and Sport Science Faculty Publications

Academic advising outcomes can be linked to both student success and retention. Yet relatively little is known specifically related to advising in physiology programs. Pro- fessional organizations dedicated to academic advising in general, and more specifically advising future health professional students exist, yet, whether current physiology programs utilize these resources remains unknown, as does a number of other demographic informa- tion about advising in physiology programs. Here we present data gathered from a sample of physiology educators to inform what current advising practices of physiology students are. Forty-five re- spondents from a variety of institutions and programs provided information on …

An Investigation Of Stress-Related Factors And Injury Occurrence In Division Iii Ice Hockey Athletes 2020., Christian Kiesel

Master's Theses

Many variables can factor into a student athlete sustaining an injury, but one of the most interesting is stress. The Stress and Injury Model is excellent in explaining how exactly history of stressors, personality, and coping mechanisms play a pivotal role in the stress response. If these three factors cause a negative stress response, then that will lead to an athlete becoming more likely to become injured. This study used 40 ice hockey players from a Division III NCAA institution. Each participant completed the Inventory of College Students’ Recent Life Experiences (ICSRLE) and Pittsburgh Sleep Quality Index (PSQI) every month …

Features Of Acceleration And Angular Velocity Using Thigh Imus During Walking In Water, Koichi Kaneda, Yuji Ohgi, Mark Mckean, Brendan Burkett

International Journal of Aquatic Research and Education

Ten participants were assessed while walking in water and on land with wearable inertial measurement units (IMUs) attached to the right thigh. Longitudinal acceleration, anterior-posterior acceleration, and frontal axis angular velocity were measured at 100 Hz, matched with video analysis sampled at 25 Hz during the walking trials. The longitudinal acceleration showed almost 1 g from initial heel contact to 70% of one cycle, and the anterior-posterior acceleration showed a sinusoidal pattern, synchronizing the approximate posture of the thigh in water. The frontal axis angular velocity fluctuated less while walking in water compared with on land, because thigh motion speed …

Kids Don’T Float…And Their Parents Don’T Either: Using A Family-Centered Approach In Alaska’S Kids Don’T Float Program, Michelle E. E. Bauer, Audrey R. Giles, Justina Marianayagam, Kelli M. Toth

International Journal of Aquatic Research and Education

The goal of this experiential report is to outline the adoption of a family-centered Kids Don’t Float approach. We conducted a critical synthesis of information to reflect the expansion of the Kids Don’t Float program into a more family-centered approach. The critical synthesis provided insights into why we should adopt this approach, how it was implemented, and how it influenced drowning incidents compared to the previously used child-centered approach. The adoption of a family-centered approach may contribute to reducing drowning incidents by targeting parents, providing safety information to families, and promoting parental modelling of life jackets.

Unanticipated Stressful And Rewarding Experiences Engage The Same Prefrontal Cortex And Ventral Tegmental Area Neuronal Populations, Alberto Del Arco, Junchol Park, Bita Moghaddam

Faculty and Student Publications

© 2020 Del Arco et al. Brain networks that mediate motivated behavior in the context of aversive and rewarding experiences involve the prefrontal cortex (PFC) and ventral tegmental area (VTA). Neurons in both regions are activated by stress and reward, and by learned cues that predict aversive or appetitive outcomes. Recent studies have proposed that separate neuronal populations and circuits in these regions encode learned aversive versus appetitive contexts. But how about the actual experience? Do the same or different PFC and VTA neurons encode unanticipated aversive and appetitive experiences? To address this, we recorded unit activity and local field …
