Should More Teams "Trust The Process" Of Tanking?, Eduardo G. Minuci, Alexander Cardazzi, Candon Johnson
Should More Teams "Trust The Process" Of Tanking?, Eduardo G. Minuci, Alexander Cardazzi, Candon Johnson
Economics Faculty Publications
In many professional sport leagues, the worst-performing teams receive higher probability of earning top draft picks. This provides teams incentives to purposefully lose, or "tank," if they are not likely to contend for the playoffs or championships. We evaluate the effectiveness of tanking to improve team outcomes by examining the most explicit tanking case in the NBA: the "Trust the Process" Philadelphia 76ers. Using synthetic control, we demonstrate that tanking caused the 76ers to be more successful in terms of winning and operating income. However, only operating income had a plausibly positive present value when calculating discounted present values.

Increasing Occupational Therapy’S Visibility In College Sports Medicine In Student-Athletes With Season-Ending Injuries, Mickaela H. Buzzy, Bonnie Fischer-Camara
Post Professional Occupational Therapy Doctoral (PPOTD) Student Capstone Projects
Sport is an essential part of a student-athlete’s life. Many student-athletes gain a strong “athletic identity” in their sport. When a student-athlete is faced with an injury, specifically a season-ending injury, they are at risk of facing a significant sense of loss of identity and adverse psychological effects on their mental health. In the collegiate athletic setting, athletic trainers are often the first to notice signs of psychological distress of student-athletes; however, they frequently report limited education, training, and confidence in providing necessary psychosocial interventions. The purpose of this capstone project was to increase occupational therapy’s visibility in the collegiate …

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
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 …

Adopting Stuart Hall’S “Race, The Floating Signifier” As A Conceptual Framework Within Aquatic Research And Education, Kurt J. Cordice
International Journal of Aquatic Research and Education
During his 1997 lecture at Goldsmiths College in London, Stuart Hall, renowned for his contributions to sociology and cultural studies, offered his argument that the concept of race functions as a Floating Signifier. In this essay, Stuart Hall’s Race, the Floating Signifier is presented as a strong conceptual framework to support more accurate and effective positioning of race as an important consideration within aquatic research and education. Evidence from a range of disciplines, including historical research, is presented to establish both the importance and challenge of race within aquatic research and education. This evidence is also used to demonstrate …

International Journal of Aquatic Research and Education
Despite the incremental increase in the number of Black people who are learning to swim, the number of Black divers has not kept pace. In the NCAA Database, swimmers and divers were not segmented; thus, they all appear in the category of “swimming” by race and sex. When viewing the 2024 Division I NCAA Demographics Database, 89 (.02%) of 4307 student-athletes participating in swimming were Black women. For men, the data is equally dismal, revealing that 81 (.03%) of 2,608 student-athletes who were identified as swimmers were Black. The purpose of this research note is to examine the developmental experiences …

The Impacts Of Sports Specialization On Youth Development, Madison M. Allen
The Impacts Of Sports Specialization On Youth Development, Madison M. Allen
Honors Thesis
To this date, there has been a rise in the professionalism of youth sports, which has increased the competitiveness and likelihood of early specialization in young athletes. While this allows youth athletes to have recognition at a young age, many athletes experience negative effects that inhibit their ability to make it to the elite level at a later age. Sports specialization can be defined as the participation and/or training of one sport year-round, typically excluding participation in all other sports. Current research suggests that sports specialization can contribute to injury and musculoskeletal disorders, impact motor skills and coordination, and cause …

Effectiveness Of An Adapted Physical Activity Program On Anxiety, Depression, And Self-Esteem On A Heterogenous Sample: A Randomized Controlled Trial, Mathilde Plard, Claire El Jor, Rebecca Shankland, Quentin Hallez
Baltic Journal of Health and Physical Activity
In recent decades, numerous studies have demonstrated the effectiveness of Adapted Physical Activity (APA) interventions in improving the mental health of individuals. However, a limitation of these studies is their predominant focus on homogeneous groups, characterized by similar diseases or disorders and characteristics. Thus, effects associated with these groups may largely account for the observed benefits, rather than the physical activity itself. This study aimed to investigate the impact of an eight-week APA intervention on anxiety, depression, and self-esteem in a heterogeneous group of participants with diverse health conditions and ages. Participants were randomly assigned to either an experimental group …

Background: Soccer matches include physical and tactical factors, yet limited research has integrated physical-tactical variables involving U21 soccer players. This study examined how different phases of play influence physical intensity in elite U21 soccer players. Materials and Methods: Twelve professional development league matches involving 29 male U21 soccer players (106 observations) were analysed. Players wore 10 Hz GPS units to derive relative (m/min) physical metrics during six phases of play. Phases and positions were compared using repeated‑measures ANOVA and one‑way ANOVA. Results: Players covered significantly greater high-speed running per minute (HSR/min) during the final third compared to build-up (p …
