‘You Have To Respect The Water’: Participant Experiences Of Appreciating And Managing The Risks Associated With Open Water Swimming – A Rapid Ethnographic Study, Mark A. Christie, David Elliott
‘You Have To Respect The Water’: Participant Experiences Of Appreciating And Managing The Risks Associated With Open Water Swimming – A Rapid Ethnographic Study, Mark A. Christie, David Elliott
International Journal of Aquatic Research and Education
Open water swimming (OWS) has rapidly grown in popularity, driven by the purported health benefits of cold-water immersion. A paucity of research remains specifically considering the notable risks inherent in OWS participation, and a lack of qualitative research on freshwater swimming experiences, and safety-related issues therein. This rapid ethnographic study, based at a dedicated OWS lake in the UK, conducted semi-structured interviews with OWS participants (n=17; female=11, male=6). Two core themes emerged: environmental issues impacting OWS experiences and behaviours; and knowledge and education of OWS which highlighted safe/unsafe practices, levels of education for managing risks, personal preparedness, swimming solo/with others, …

Barriers: Location, Functionality, And Method Of Access In Childhood Pool/Spa Submersion Incidents, United States, 2000-2017, Alison Miller, Kristina R. Anderson, William D. Ramos
International Journal of Aquatic Research and Education
Drowning is a leading cause of fatality among children in the United States, and residential pools/spas currently account for as much as 80% of these submersion incidents. This study reviewed narrative case reports obtained from the United States Consumer Product Safety Commission (CPSC) to understand barrier location, type, and functionality as methods of pool/spa access for childhood submersion incidents. Retroactive analysis of 1,523 fatal and non-fatal submersion incidents among children aged 13 years old and younger was conducted using the CPSC in depth investigation dataset from 2000-2017. Narrative descriptions were coded according to the attributes of barrier location, functionality, and …
Lay Rescuer Equipment Preferences And Efficacy During A Simulated Drowning Event, Alison M. Miller, William D. Ramos, Kristina R. Anderson, Jill Cuvala
Lay Rescuer Equipment Preferences And Efficacy During A Simulated Drowning Event, Alison M. Miller, William D. Ramos, Kristina R. Anderson, Jill Cuvala
International Journal of Aquatic Research and Education
During a drowning incident where a lifeguard is not present, a bystander – referred to as a lay rescuer - may put themselves in danger by attempting a rescue. When lay rescuers can avoid entering the water by using rescue equipment to help a drowning victim, it serves to not only help the person actively drowning, but also provides a layer of protection to a lay rescuer. This study sought to examine the following questions: (a) which pieces of rescue equipment were preferred by lay rescuers at pre-determined short and long distances, (b) do lay rescuers select appropriate rescue equipment …

Meeting, Moving, Mastering - A Text Analysis Of The Aesthetic Attractions Of 'Wild Swimming', Dagmar Dahl, Åsa I. Bäckström
International Journal of Aquatic Research and Education
Why are people fascinated by swimming in nature? This article addresses the aesthetic experiences of wild swimming as expressed by five wild swimming authors in their books. Drawing from aesthetic philosophy, we analyze the ways in which the appeal of wild swimming is described on three levels: the allure of water in the environment, the sensory encounter between water and the body, and the experience of moving in water. Furthermore, with reference to Seel’s concept of nature aesthetics (1996), the experience of wild swimming is analyzed in terms of contemplation, correspondence, and imagination. We can conclude that the special intensity …
Towards A Globalised Vision Of Aquatic Competence, Rita F. Pinto, Juan Antonio Moreno Murcia
Towards A Globalised Vision Of Aquatic Competence, Rita F. Pinto, Juan Antonio Moreno Murcia
International Journal of Aquatic Research and Education
Human interaction with the aquatic environment has always taken different forms to meet the needs of pleasure, survival, therapy or performance. The diversity of existing aquatic spaces presents itself as a challenge, due to their variety, dynamism, unpredictability and unrepeatable conditions. These factors potentiate an infinite number of possibilities for human response in interaction with the aquatic environment, with aquatic competence being the one that will be able to sustain all types of interaction. Thus, the aim of the proposal has been to present a new approach to the contextualisation of aquatic competence. After a literature review on the concept …

International Journal of Aquatic Research and Education
The aim of this article is to address the familiar question “Which swimming stroke should be taught first?” The discussion is usually focused on breaststroke versus crawl. Provoked by these naïve discussions of which stroke should be taught first (as if stroking equals swimming, which it emphatically does NOT), the question was answered metaphorically in an earlier article “No Stroke First – All Strokes First” (Stallman, 2008a). Here in Part I we identify and describe six strokes, all of which might be a candidate for any learners ‘very first’ stroke. We describe them as beginning strokes. Having identified and learned …

The Real-Time Classification Of Competency Swimming Activity Through Machine Learning, Larry Powell, Seth Polsley, Drew Casey, Tracy Hammond
International Journal of Aquatic Research and Education
Every year, an average of 3,536 people die from drowning in America. The significant factors that cause unintentional drowning are people’s lack of water safety awareness and swimming proficiency. Current industry and research trends regarding swimming activity recognition and commercial motion sensors focus more on lap swimming utilized by expert swimmers and do not account for freeform activities. Enhancing swimming education through wearable technology can aid people in learning efficient and effective swimming techniques and water safety. We developed a novel wearable system capable of storing and processing sensor data to categorize competitive and survival swimming activities on a mobile …
Do Water Safety Lessons Improve Water Safety Knowledge?, Michael J. Tipton, Joseph Muller, Cristian Abelairas Gomez, Jo Corbett
Do Water Safety Lessons Improve Water Safety Knowledge?, Michael J. Tipton, Joseph Muller, Cristian Abelairas Gomez, Jo Corbett
International Journal of Aquatic Research and Education
A person, usually a child or young adult, dies by drowning every 90 seconds around the planet. Most drowning prevention initiatives do not assess the efficacy of the intervention. In this study, thirteen- to fourteen-year-olds had their level of water safety knowledge (covering cold shock, rips and tides) assessed before, just after, and 3-6 months after one, 25-minute water safety lesson on these topics. We evaluated the knowledge gained and retained on water safety “awareness” (i.e., knowledge of risks) and “confidence” in terms of knowing what to do in an emergency. The results demonstrated that the lesson significantly increased water …

I walked into the classroom feeling nervous. It wasn't my first time teaching undergraduate students about human endocrine physiology. I knew the material well. But today's lecture was different. I pulled up slides depicting a hypothetical cancer patient and told them, “Patient X had a biopsy that detected invasive carcinoma in her breast.” I described the many months of chemotherapy, surgery, and radiation treatments she went through before going into remission. Then I taught the students about the hormonal therapy she was prescribed—drugs her doctor hoped would limit the growth of any remaining cancer cells and prevent a recurrence. On …

Perceptions Of Water Competencies, Drowning Risk And Aquatic Participation Among Older Adults, Teresa Stanley, Kevin Moran
Perceptions Of Water Competencies, Drowning Risk And Aquatic Participation Among Older Adults, Teresa Stanley, Kevin Moran
International Journal of Aquatic Research and Education
New Zealand has an aging population and, despite falling drowning tolls in all other age groups (WSNZ, 2019c), older adults have continued to drown in both increasing numbers and proportion. The reasons for this are not well understood since very little drowning research has focused on older people. A water safety survey (N = 389) seeking information on older adults’ aquatic recreational practices and perceptions of safety was conducted at the end of the summer season, 2019. Most adults (86%, n = 335) reported some aquatic activity in the previous year, but those aged 65+ years (66%) were significantly …

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 …

Undergraduate degree programs named “Physiology” have existed for over 50 yr. The number of programs and enrolled students have been growing since ~2005 (5, 9). There are many thousands of students currently enrolled in physiology pro- grams across the United States and indeed across the world. Despite the long history and current popularity of the physiol- ogy major, there is no coordinated plan articulated for the design, administration, or assessment of degree programs in physiology at the undergraduate level.
Although several professional societies have invested in under- graduate physiology education in various ways, none has under- taken the task of …

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 …
