Evolution As Spatial Projection, Charles H. Smith, Ngoc Nguyen
Evolution As Spatial Projection, Charles H. Smith, Ngoc Nguyen
Faculty/Staff Personal Papers
A theory combining explanations for the nature of three-dimensional systems and evolutionary processes is advanced, set to a geometric simulation, and then discussed in the context of several empirical studies bearing on its validity. The concept “evolution” is first discussed, then related to Baruch de Spinoza’s ideas on natural philosophy, including his concept of the conatus. These ideas are then extended by posing the possible existence of a general form of natural systems subsystemization leading to the extended space condition. A geometrical/topological simulation study projecting spatial relations among subsystem structures interpretable through entropy maximization and multidimensional scaling methods is presented, …

Alfred Russel Wallace Notes 39. What About Wallace's 'Agnosticism'...?, Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace (1823−1913) seems to have distinguished his earlier years of agnosticism from his later period as a spiritualist, but a closer look at the situation suggests he actually remained an agnostic all the way through to the end of his life. The confusion is occasioned by a lack of terminology that can be applied to his position, which most closely resembles a Spinozian manner of thinking.

A Novel Method For Producing Muscle Cramps Without Electrical Stimulation, Elizabeth C. Krajca, Benjamin Greengold, Edward Merritt
A Novel Method For Producing Muscle Cramps Without Electrical Stimulation, Elizabeth C. Krajca, Benjamin Greengold, Edward Merritt
International Journal of Exercise Science: Conference Proceedings
Muscle cramps are involuntary, often painful, skeletal muscle contractions that can occur for multiple reasons including physical exertion, injury, dehydration, nutritional deficiencies, or other neuromuscular conditions. Understanding muscle cramping etiology and treatments is difficult due to their often unpredictable timing and conditions that need to be met for many individuals to experience them. Previous studies have induced muscle cramping through electrical stimulation, long duration exercise, dehydration, and other methods, but these techniques are either non-physiological or complex and time attentive. PURPOSE: Therefore, we aimed to develop a new method to produce a muscle cramp in the biceps brachii in a …

A Comparative Analysis Of Maladaptive Perfectionism In Male And Female Competitive Bodybuilders, Maddox B. Utter, Christian O. Quintero, Samantha S. Dardaman, Stephen E. Rowden, Scott B. Martin
International Journal of Exercise Science: Conference Proceedings
Bodybuilding is a sport focused on physique optimization, where success is determined by judges’ evaluations of muscle mass, symmetry, and definition. Due to the sport’s emphasis of physical aesthetics, bodybuilders may feel the need to compare themselves with other competitors. This evaluation and comparison of physique may expose athletes to maladaptive perfectionistic tendencies, such as setting unattainably high standards, excessive worry over mistakes, and a diminished sense of competence. While current bodybuilding literature is limited, previous research suggests that perfectionism may lead to psychological impairments (e.g., body dysmorphia, anxiety, and reduced self-confidence) which may manifest differently between male and female …

Validation Of Bertec Force Plate Treadmill For Asymmetry Measures, Miah A. Barras, Olivia D. Broaddus, Dacia Martinez-Diaz, Charles Layne, Craig Johnston
International Journal of Exercise Science: Conference Proceedings
BACKGROUND: The current literature establishes the existence and detrimental impact of high levels of asymmetry in a range of physical capacities in the general population as well as performance athletes. Given the influence of symmetry, there is a need to identify validated ways to measure it. Despite this, no uniform method of quantifying inter-limb differences exists to date. Furthermore, few studies compare bilateral data when limbs act concurrently as a functional system. One possible application of this measure is to measure the impact of an asymmetric training protocol on bilateral force production. Its theoretical applications remain untested in many circumstances, …

Carbohydrate Effects On Cycling Time To Exhaustion Following Exercise-Induced Glycogen Depletion: Preliminary Data, Ross Moody, Nicole Cipriano, Macilynn E. Coles, Jason Stephens, Sarah Deemer
International Journal of Exercise Science: Conference Proceedings
PURPOSE: In recent years, there has been a rise in the popularity of zero sugar sports drinks which contain fewer calories (from reduced carbohydrate (CHO) content), while maintaining identical electrolyte content. However, substantial evidence demonstrates that CHO consumption before or during exercise enhances performance and supports recovery. Because zero-sugar sports drinks contain only a fraction of the carbohydrate found in traditional full-sugar formulations, they may be less effective for supporting recovery and subsequent performance following muscle-fatiguing exercise. This study investigates whether consuming a full sugar (CHO+), a zero-sugar (CHO-), or water drink following lower-body muscle fatiguing exercise improves cycling …

Firefighting requires repeated bouts of high-intensity physical work performed under extreme environmental conditions, placing substantial strain on the cardiovascular and musculoskeletal systems. Cardiovascular disease (CVD) remains the leading cause of on-duty firefighter fatalities, with the majority of deaths occurring among firefighters aged 40 years and older. Physiological characteristics such as age and body composition influence aerobic capacity and maximal work performance, both of which are critical and essential while performing strenuous operations. PURPOSE: The purpose of this study was to examine how age, sex, and body composition affect aerobic capacity (VO2peak) and maximal work capacity (Wmax …

Prolonged sedentary behavior among university students, faculty, and staff is associated with increased risk of chronic disease, poorer mental well-being, and diminished academic and occupational performance. As institutions seek practical strategies to integrate movement into the day, active workstations (e.g., sit-to-stand desks and desk bikes) have emerged as a promising approach to reduce sitting time while supporting productivity and overall health. PURPOSE: To evaluate the use of active workstations among the Southwestern University community and examine their perceived impact on physical activity levels, productivity and focus, stress and anxiety, and overall sedentary behavior. METHODS: Twenty-six participants (faculty, staff, and students) …
