The purpose of this study was to investigate the attitudes and self-efficacy of swimming coaches regarding the inclusion of swimmers with autism spectrum disorder (ASD). The sample consisted of 150 Greek swimming coaches with an average age of 29.58 years. Each participant completed the Swimming Coaches Attitudes towards Inclusion Questionnaire for perceptions assessment and the Biddle and Goudas (1997) self-efficacy questionnaire. The statistical analysis used SPSS 27 to calculate Cronbach’s alpha, Pearson product-moment correlations, independent t-tests, and ANOVA. The findings of the study showed that the swimming coaches expressed positive attitudes and a high percentage of perceived self-efficacy towards the …
‘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, …

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 …

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 …

International Journal of Aquatic Research and Education
The primary goal of this two-part project is to answer the rhetorical question of which strokes should be taught first, and which later (Langendorfer, 2013, Stallman, 2014a). As you have seen in Part One, we emphasize (as have many others) the need for a firm foundation before any stroke is introduced. When the learner is ready for propulsive motor competencies, there is no stroke which suits all as their first. In Part One we explored the “beginning strokes” all of which are candidates for any given learner’s first stroke. We also argued that after mastering their very first stroke the …
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 …
Revisiting The Metaphorical Concept Of “No Strokes First - All Strokes First”: Part One - Beginning Strokes, Robert Keig Stallman Ph.D., Alex Mwaipasi, Ebbe Laakso Horneman, Nils Olof Vikander, Bente Wäinösdatter Horneman Laakso, Haakon-Paavo Laakso Nysted, Toni Ongala

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 …

Employment With The Northwest Territories Aquatics Program: A Significant Life Event?, Sebastien Denize, Audrey R. Giles
International Journal of Aquatic Research and Education
For over 60 years, the Northwest Territories Aquatics Program (NWTAP) has employed university students from southern Canada with little to no exposure to northern Canada to run seasonal swimming pools and waterfronts in isolated northern communities. In this article, we examine the impact that working for this program had on nine former employees’ lives and whether or not working for the NWTAP could be categorized as a significant life experience. We used thematic analysis of the data from retrospective semi-structured interviews and open-ended questionnaires and identified four themes: (1) employment by the NWTAP enhanced the employees’ self-confidence, independence, and self-efficacy; …

International Journal of Aquatic Research and Education
Exercising using an underwater treadmill (UTM) has become a popular modality; however, few studies have focused on the physiological demands of UTM walking at varying water depths. Thus, the objective of this study was to investigate changes in heart rate (HR) and core temperature (CT) values in college-aged males and females while exercising at different water immersion depths using an UTM. Twenty participants (age = 21.50 ± 2.19 years; height = 169.04 ± 10.85cm; weight = 75.56 ± 22.28kg) walked at water depths of 10cm below the xiphoid process and at the level of the superior iliac crest (I.C.). Each …

International Journal of Aquatic Research and Education
Drowning represents a leading cause of unintentional deaths among children. Concomitantly, while formal swim instruction often incorporates water safety practices, the efficacy of these messages remains largely unexplored. This qualitative-based study sought to evaluate how youth apply learned water safety concepts when posed with a hypothetical aquatic scenario. Semi-structured interviews, augmented by use of a visual illustration prompt, were conducted with 29 participants of a youth Learn-to-Swim (LTS) program. Interviews assessed participants’ expressed water safety behaviors and were coded based on emergent themes. Findings indicated that most participants were able to identify a “struggling” swimmer in the dramatized illustration. When …

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 …

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 …
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 …

Predicting Young Adults’ Intentions And Involvement In Alcohol-Influenced Aquatic Activity, Hannah L M Calverley, Lauren A. Petrass Ph.D., Jennifer D. Blitvich
International Journal of Aquatic Research and Education
Globally, alcohol consumption is a public health issue and a risk factor for drownings among young adults. While studies have identified a prominence of alcohol in youth drownings, little is known about the factors that influence young adults’ involvement in alcohol-influenced aquatic activity. The current study aimed to identify the predictors of young adults’ intention to participate, and past participation, in alcohol-influenced aquatic activity. A reliable and valid survey, informed by the Theory of Planned Behavior, was distributed to young adults (aged 18-24 years) educated in the UK and Australia. Cumulative odds ordinal logistic regressions with proportional odds were …

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 …
Black Drowning Deaths: An Introductory Analysis, Alena Gadberry, James Gadberry
Black Drowning Deaths: An Introductory Analysis, Alena Gadberry, James Gadberry
International Journal of Aquatic Research and Education
Black children between the ages of 5 and 14 are 2.6 times more likely to drown than white children. A systematic exclusion from public pools and other forms of water activities over time has led to a lack of cultural capital involving aquatics among black families. Pierre Bourdieu has provided a theoretical foundation in which to understand this issue. The social fields created by generational socialization have made blacks feel like they have no place in the water. It will take a restructuring of the social institutions to set in motion the socialization (or a re-socialization) of new and more …

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 …

The Ocean Lifeguard Intervention Continuum: A Cognitive Aid For Surf Lifeguard Education, William A. Koon, Ryan M. Gates, Shane Scoggins, Paul Andrus, Jack A. Futoran
International Journal of Aquatic Research and Education
Ocean lifeguards are constantly engaged in beach risk analysis, required to efficiently evaluate a variety of environmental and other factors quickly in order to triage and prioritize who needs help. Teaching these skills is a challenge for introductory training programs. We sought to improve new lifeguards’ understanding of the interaction of various risk components in the beach environment and aid decision-making related to when a lifeguard should intervene in a situation. We developed a two-part cognitive aid for introductory ocean lifeguard education depicting individual and interacting elements of a beach goer’s risk of drowning or injury and the process by …
