Where Is The Power In A Power Analysis?, Kevin D. Dames, Zoe Climenhaga, Jared Rosenberg

International Journal of Exercise Science

International Journal of Exercise Science 18(2): 1114-1120, 2025. https://doi.org/10.70252/AVGK2063 Strategic planning of research involves predicting the number of replications of the experiment needed to detect an expected effect. The power analysis to determine sample size for the proposed experiment requires known or estimated characteristics of existing distributions. When used well, power analysis reduces the risk of statistical errors, wasted efforts, and temptations to twist ensuing analyses to eke out a ‘significant’ result after data collections conclude. This editorial highlights some examples of how this process goes awry. Sections are dedicated to the role of researchers, the case for ‘pilot’ studies, …

Goals Reconsidered: From Brute Prelusory States Of Affairs To The Lusory Complexity Of Sport, Francisco Javier López Frías

Kinesiology and Health Science Faculty Publications

In this paper, I examine Bernard Suits’ conceptualization of goals in his influential definition of gameplay, focusing on how his account falls short of capturing the complexity of sporting practices. Suits famously describes games as voluntary attempts to overcome unnecessary obstacles in achieving an identifiable state of affairs. By referring to this state of affairs as the prelusory goal of games, he frames gameplay as structured teleologically around this goal, converting it into the most fundamental element of his notion of gameplay. Although elegant and very intuitive, this conception of games raises tensions when applied to the complex, multilayered activities …

The backdrop to the case is that a recreational therapy intern worked with various special needs populations – mainly with paraplegic (adult and youth) athletes and veterans. In many organizations, user conflicts and poor communication regarding service provision and scheduling hinder the implementation of programs for special populations, such as veteran groups. In this case, a problem occurred with the scheduling of a water aerobics program for …

Curbing Fatal And Non-Fatal Drowning Deaths: An Effort To Reach Under-Resourced Children In Baltimore, Maryland, Ashton P. Christo, William D. Ramos

International Journal of Aquatic Research and Education

Drowning remains a significant public health problem in the United States, with The Centers for Disease Control and Prevention (CDC) reporting approximately 4,000 drowning deaths annually. Children aged 1-4 face the highest risk, and African American children are disproportionately affected–7.6 times more likely to drown than white children (CDC, 2024). In a city on the East Coast that is predominantly African American, limited access to swimming lessons heightens the risk. To reduce drowning rates, a collaborative swimming program was established between a city high school and a public school enrichment program. The initiative provided essential water safety and swimming skills …

If We Tear It Down, We Might Build You A New One: The Troublesome Use Of Eminent Domain And Urban Neighborhood Swimming Pools, Steven N. Waller Ph.D., James H. Bemiller

International Journal of Aquatic Research and Education

Public swimming pools are a vital part of America’s recreation and sport culture since the early 1900’s. Municipal swimming pools were initially built to provide recreation and hygiene to urban communities, regardless of race or class. However, a complex history of segregation, civil unrest, suburbanization, and funding challenges has resulted in a significant decline in public pools, depriving many communities of vital recreational spaces. In many communities, options for sustaining the operation of swimming pools have resulted in pool closures. Unfortunately, once swimming pools close, especially those in aging neighborhoods in central city areas, they are seldom resurrected. They quickly …

Teaching Swimming To Children With Disabilities: A Qualitative Analysis Of Swim Instructorstea, Stephanie S. Garcia-Hidalgo, Martin E. Block

International Journal of Aquatic Research and Education

When teaching children with disabilities, swim instructors need to be able to assess the unique strengths and needs of each child to determine modifications needed to instruction, equipment, and the setting and then be flexible enough to make changes in real-time to ensure success for the child. Unfortunately, many swim instructors only work seasonally and have the occasional child with a disability, and as a result are likely to have limited training and experiences with children with disabilities. The purpose of this pilot qualitative study is to examine backgrounds, training, and experiences of six swim instructors who work with children …

Promising Practices For Increasing The Number Of Equity-Owed Lifeguards In Canada And The United States Of America, Sofia Pantano, Audrey R. Giles

International Journal of Aquatic Research and Education

Currently a shortage of lifeguards exists in Canada and the United States (US) (Frommer, 2023; Santucci, 2024), and those who are working as lifeguards often do not reflect the diversity of the communities they serve (Martinez, 2020). Increasing the number of lifeguards from equity-owed groups is a potential way of increasing the lifeguard workforce and decreasing the shortage of workers in these important roles, as well as a moral imperative. In this paper I explore challenges to and promising practices aimed at increasing the representation of members equity-owed groups in lifeguarding. I begin with an overview of lifeguarding in Canada …
