Neural Efficiency Hypothesis In Motor Actions; Spectral Power Of Balancing Ballet Dancers, Carter G. Disantis

Senior Theses

Reduced activity observed during functional imaging of motor experts led to the Neural Efficiency Hypothesis (NEH) in motor skills, which posits that expert performers use fewer neural resources during motor execution than novices, reflecting greater neural efficiency.

This pilot study compared EEG recordings from five novices and four expert ballet dancers during standing and one-leg balance. Whole-brain theta (4–8 Hz) and alpha (8–12 Hz) power were quantified, and topographic maps were generated. In addition to testing the primary hypotheses, the experimental design was evaluated as a practical and scalable approach for investigating the NEH in motor skills. Novices showed significantly …

Effects Of Interval Load And Constant Load Cycling On Cortisol And Testosterone Production, Anna Zurlo

Creatine Supplementation Is Safe, Beneficial Throughout The Lifespan, And Should Not Be Restricted, Richard Kreider, Andrew Jagim, Jose Antonio, Douglas Kalman, Chad Kerksick, Jeffrey R. Stout, Robert Wildman, Rick Collins, Diego A. Bonilla

Faculty Scholarship

As researchers investigating creatine supplementation, we have become increasingly concerned about reports that government agencies are attempting to restrict the sale of dietary supplements, including dietary supplements containing creatine, to children and adolescents. Creatine is a naturally occurring compound found in every cell in the human body that plays a critical role in cellular metabolism. The daily turnover of creatine is about 2–4 grams/day, depending on muscle mass and physical activity levels (1, 2). About half of the daily need for creatine is synthesized in the body from amino acids (arginine, glycine, methionine) and stored as free creatine or phosphocreatine …

"Feel For The Water": What Is It, Really?, Robert Keig Stallman, Kristine De Martelaer

International Journal of Aquatic Research and Education

The phrase, 'feel for the water,' is commonly used. But what does it really mean? The traditional idea of this 'feel' focuses on the sensation of touch and use of the hands to produce propulsion. But what about water resistance? Mastering a feel for how to reduce resistance is equally important as the unique relationship between aquatic propulsion and resistance is of great importance. While being in the water, the effects of gravity and buoyancy also need to be perceived by the learner and taught by the instructor. Reflection on the effects on propulsion-resistance and gravity-buoyancy requires relevant exercises to …

Fighting Instinct: The Brain, Emotions And Decision-Making In The Water, Jill Nash, Sam Hills

International Journal of Aquatic Research and Education

This conceptual paper explores the complex interplay among the human brain, emotions, and decision-making processes, particularly in aquatic environments. Integrating insights from neuroscience, psychology, and behavioural economics, we investigate how instinctual responses and emotional states influence our decisions during water-related activities. By analysing both biological and psychological factors, the paper aims to illuminate the intricacies of human behaviour in various aquatic settings and highlights significant gaps in the research on emotional decision-making that warrant further investigation. Additionally, the paper suggests interventions, including plausible communication strategies, to mitigate the impact of instinctual responses and improve safety and decision-making efficiency.

Goggles And Water Competence: An Addendum, Marek Rejman, Robert Keig Stallman Ph.D.

International Journal of Aquatic Research and Education

We offer this short addendum to the 2017 article that appeared in IJARE, ‘’From swimming skill to water competence: Towards a more inclusive drowning prevention future’’ (Stallman et al., 2017), as an editorial to argue that the essential water competencies ought to be mastered “without goggles.” The focus is on the potential negative effect of goggle use during beginning swimming instruction along with their likely absence during unintended and unexpected immersions in natural bodies of water that often lead to drowning. Rejman and Stallman (2024) demonstrated the development of dependence on goggles among young adults and described its negative effect …
