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, …

Getting In: Safe Water Entry Competencies, Kevin Moran Dr, Jennifer Blitvich, Lauren Petrass, Keith Mcelroy

International Journal of Aquatic Research and Education

In high income countries, jumping and diving into water are a small but persistent cause of death and serious injury especially among male youth and young adults. Although water entries maintain a high media profile, little is known about what entry competencies and underlying water safety knowledge youth bring to this practice. Undergraduates enrolled in aquatics (N= 76) completed a survey before attempting 7 entry jumping and diving tasks. While safety attitudes and self-reported behaviours were generally good, considerable variation in practical entry competence was evident. Most completed a deep-water compact jump (87%) and PFD jump (88%) with …

The Lifeguard Rescue Reporting System: Survey Results From A Collaborative Data Collection Method, William D. Ramos, Roy Fielding, Kristina R. Anderson, Peter G. Wernicki Md

International Journal of Aquatic Research and Education

Several water safety organizations have attempted to improve reporting regarding lifeguard actions in order to better understand the characteristics of successful, non-fatal rescues. In 2003, a collective effort initiated the Lifeguard Rescue Reporting System, an online survey distributed to lifeguards and facility managers across the United States and Canada to better understand rescue actions performed in pools/spas, water parks, and open water areas. After seven years of data collection, the online survey accumulated data reflecting 1,676 rescue actions, collecting information including location, victim characteristics and outcome, rescuer characteristics and strategies, and other general circumstances. Descriptive results indicated that at least …

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 …

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 …

Hasselfeld Ms, Violet T. Schramm, Angelo J. Colosimo Md, Aaron Kuehn-Himmler At Ms, Gerald M. Holloway Ms Atc, Faniel Fosselman Do Mba, Jon Vincent, Nicole Giordano, Jon G. Divine Md Ms

Journal for Sports Neuroscience

Introduction.

Concussions are of significant concern for athletic trainers, and there is a critical need to objectively and safely allow an athlete to return to play. In sports the objective is return as safely and soon as possible. Exertion is a consideration regarding progressing an athlete back to play. The ability to exert in cardiovascular and strength and conditioning contexts are two critical steps in most return to play protocols. Being able to make objective recommendations is urgently needed, as trial and error leads to unnecessary risk of eliciting symptoms and/or causing setbacks.

Objective.

Journal for Sports Neuroscience

Abstract.

Introduction

Sports related concussion, also considered mTBI, has remained in the public eye due to heightened fear concerning playing football and other collision based sports. Concussion prevention, as well as rehabilitating the brain after a concussion, is a high priority for many sports medical practitioners as well as for athletes. For these reasons, researchers associated with the American Athletic Conference (AAC) have surveyed concussion incidence in football. One of the AAC teams engaged in regular neurovisual training (NVT) and concluded this training program is associated with faster return to play post-injury in this observational cohort study.

Applications Of The Critical Power Model To Dynamic Constant External Resistance Exercise: A Brief Review Of The Critical Load Test, Haley C. Bergstrom, Taylor K. Dinyer, Pasquale J. Succi, Caleb C. Voskuil, Terry J. Housh

Kinesiology and Health Promotion Faculty Publications

The study and application of the critical power (CP) concept has spanned many decades. The CP test provides estimates of two distinct parameters, CP and W′, that describe aerobic and anaerobic metabolic capacities, respectively. Various mathematical models have been used to estimate the CP and W′ parameters across exercise modalities. Recently, the CP model has been applied to dynamic constant external resistance (DCER) exercises. The same hyperbolic relationship that has been established across various continuous, whole-body, dynamic movements has also been demonstrated for upper-, lower-, and whole-body DCER exercises. The asymptote of the load versus repetition relationship is defined as …

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 …

Effects Of A Dual-Task Paradigm On Tandem Gait Performance, Courtney Angela Perry

Cal Poly Humboldt theses and projects

In concussion management, a variety of cognitive and motor control tests, like the tandem gait, have been used for assessing the presence of a concussion injury at the sideline and through recovery. More recently, research suggests that introducing a secondary cognitive retention task during tandem gait (i.e., dual task) may provide a better assessment of concussion. The purpose of this study was to determine if a tandem gait test paired with a 6-digit retention is a valid and reliable tool. Participants completed three trials of both the single-task (ST) and dual-task (DT) tandem gait tests, and their average (MEAN) and …
