This study examined heart rate (HR) and stride frequency (SF) values of 30 college-aged males and females during dry-land (DL) and aquatic walking (AW). Aquatic walking trials were completed in an underwater treadmill with the water depth at waist level; the water temperature (31℃ ± 0.1℃) and room temperature (26.6℃ ± 0.1℃) were maintained at thermoneutral levels throughout the study. During each walking condition, HR and SF were recorded at treadmill speeds of 1 mph, 2 mph, and 3 mph. Participants were instructed to walk with their hands at their sides swinging as they would when walking on dry-land unless …


Features Of Acceleration And Angular Velocity Using Thigh Imus During Walking In Water, Koichi Kaneda, Yuji Ohgi, Mark Mckean, Brendan Burkett May 2020

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. Program evaluators and water …

Wai Puna: An Indigenous Model Of Māori Water Safety And Health In Aotearoa, New Zealand, Chanel Phillips Ph.D. Apr 2020

Wai Puna: An Indigenous Model Of Māori Water Safety And Health In Aotearoa, New Zealand, Chanel Phillips Ph.D.

International Journal of Aquatic Research and Education

Māori (the indigenous peoples of Aotearoa, New Zealand) are intimately connected to wai (i.e., water) yet are overrepresented in New Zealand’s drowning statistics each year. On average Māori account for 20-24% of all preventable and non-preventable drowning fatalities, despite comprising only 15 percent of New Zealand’s population. Drowning remains a significant issue posing a threat to whānau (i.e., families) through premature death being imminent and whakapapa (i.e., genealogy) being interrupted. There is limited research that has examined Māori and indigenous understandings of water safety within the literature and limited studies that have investigated the issue of Māori drowning from a …

Ocean lifeguards have several responsibilities that require precise training. California State Parks is one of the largest providers of open water lifeguard services in the United States, and trains approximately 200 new lifeguards per year. As part of our lifeguard training section’s quality improvement efforts, we conducted a training needs assessment to help determine how well our introductory ocean lifeguard training curriculum prepared lifeguards to perform job related tasks upon successful completion of the training program. We surveyed both first year and seasoned lead lifeguards on operational needs, training gaps, and specific subject areas. We identified several areas where our …


Alcohol_Focused Drowning Prevention Campaigns: What Do We Know And What Should We Do Now?, Hannah Calverley, Lauren Petrass, Jennifer Blitvich Apr 2020

Alcohol_Focused Drowning Prevention Campaigns: What Do We Know And What Should We Do Now?, Hannah Calverley, Lauren Petrass, Jennifer Blitvich

International Journal of Aquatic Research and Education

Alcohol and drugs have been identified as key risk factors for youth (aged 15-24 years) and adult drownings in high-income countries (HIC). Whilst alcohol specific drowning prevention education programs have been developed and implemented, youth continue to be over-represented in drowning statistics, including those linked with alcohol. Therefore, this project aimed to: (i) review and assess all alcohol themed drowning prevention campaigns within HICs; (ii) determine whether the campaign had undergone evaluation for effectiveness; and (iii) provide recommendations to improve the effectiveness of future interventions. For each of the eighty-one HICs identified for the 2019 fiscal year, searches of peer-reviewed …


Socio-Ecological Nature Of Drowning In Low- And Middle-Income Countries: A Review To Inform Health Promotion Approaches, Muthia Cenderadewi, Richard Charles Franklin, Susan Devine Apr 2020

Socio-Ecological Nature Of Drowning In Low- And Middle-Income Countries: A Review To Inform Health Promotion Approaches, Muthia Cenderadewi, Richard Charles Franklin, Susan Devine

International Journal of Aquatic Research and Education

Most deaths by drowning (91%) have occurred in low- and middle-income countries (LMICs), particularly in Southeast Asia (35%) and Africa (20%), in proportion to total drowning deaths worldwide. Poor data collection in LMICs hinders the planning, implementation, and evaluation of prevention strategies. The objective of this study was to review the rates and risk factors of unintentional drowning in LMICs and to identify drowning prevention strategies within a socio-ecological health promotion framework. A systematic search, guided by PRISMA, was conducted on Ovid MEDLINE, CINAHL, Informit health, PsycINFO (ProQuest), Scopus, SafetyLit, Google Scholar, and BioMed Central databases for all relevant studies …

The Assessment Of Swimming And Survival Skills: Is Your Programme Fit For Its Purpose?, Paolo Di Paola Aug 2019

The Assessment Of Swimming And Survival Skills: Is Your Programme Fit For Its Purpose?, Paolo Di Paola

International Journal of Aquatic Research and Education

Assessment of swimming and survival skills is a crucial part of any swimming and lifesaving programme. Unfortunately, quite often, it is also the weakest part of the programme itself. Inadequate skills assessment and verification might lead to ineffective skills acquisition and development, to a false sense of safety and over confidence in the water that can be extremely dangerous. Assessor experience and observation skills, assessment methodology, and criteria are all closely inter-linked and their interaction will somehow determine the assessment outcomes. Our paper analyses some of the current issues in these areas of the assessment process, such as assessor’s lack …

Drowning is a leading cause of death for US children. Teaching youth to swim in a formal setting from certified instructors is a consistent drowning prevention recommendation. Purposes for this investigation was to examine type of swimming instruction and ability to swim and compare to attitudes toward swimming among US youth. Methods were similar to previous USA Swimming studies in 2008 and 2010. YMCA associations in five cities were used to recruit adolescent survey respondents (n=600) aged 12-18 years. Results showed African American youth had the lowest rate of formal swimming instruction (29%) compared to White (32%) and Hispanic (42%) …


Revised Scientific Review: Minimum Age For Swim Lessons, Stephen J. Langendorfer Ph.D. Jan 2019

Revised Scientific Review: Minimum Age For Swim Lessons, Stephen J. Langendorfer Ph.D.

International Journal of Aquatic Research and Education

The question addressed in the original scientific review (2009) was rephrased as Does sufficient scientific evidence exist to support setting a minimum age for swimming lessons? for this triennial review. Addressing the research question is significant because strong differences of opinion about the appropriate age(s) for initiating learn-to-swim lessons have existed among the pediatric medical profession, aquatic professionals and agencies, and proprietary programs and swim schools for over four decades. The question has implications for the appropriate purposes, pedagogies, and outcomes associated with swimming experiences for infants and young children that will be addressed in a subsequent review. The revised …


Drowning Prevention: Define And Then Gather Evidence Or Gather Evidence To Define?, Nina J. Nyitrai, Suzi Edwards, Nicholas O'Dwyer Dec 2018

Drowning Prevention: Define And Then Gather Evidence Or Gather Evidence To Define?, Nina J. Nyitrai, Suzi Edwards, Nicholas O'Dwyer

International Journal of Aquatic Research and Education

According to the World Health Organization, drowning fatalities are a neglected public health issue ranked as the third most frequent cause of unintentional death by injury. Data used to record drowning incidents are acknowledged as inaccurate. Recommendations on drowning prevention based on these data are currently not informed by accurate, detailed and reliable evidence. Two modifications to current practice are proposed: 1) an Aquatic Incident Report needs to be developed as an extension of the current workplace incident report to prompt for information commonly not included in current drowning reports; and 2) National Water Safety Plans should be modified to …
