Slouching Towards Inefficiency? The Cardiometabolic And Cognitive Costs Of Poor Posture, Ava Mae Fitzenrider

Honors Projects

Posture affects all of our lives. It is both static and dynamic, adapting continuously to environmental demands. One postural alteration frequently observed in occupational settings is hyperkyphosis, which can be induced by sitting position. During computer use, individuals commonly adopt a slouched posture, which can exacerbate hyperkyphosis, and contribute to dis-ease within the body. Previous research has demonstrated that such postural deviations can negatively affect pulmonary function, as well as other bodily functions. Despite these findings, the effects of acute hyperkyphosis (“slouching”) on cardiometabolic function and cognition remain largely unexplored. Therefore, the purpose of this study was to examine the …

The Effect Of Acute Hypoxia Exposure, With Exercise, On Bone Metabolic Biomarkers, Alyssa Bailly

Health, Exercise, and Sports Sciences ETDs

Hypoxic environments, resulting from decreased atmospheric partial pressure of oxygen, reduce oxygen availability in the blood and tissues, leading to a mismatch between supply and demand. This elicits several physiological adaptations and may influence bone metabolism. Although evidence suggests that hypoxia can modulate bone remodeling through hypoxia-inducible pathways, findings remain mixed, with most data derived from chronic hypoxic exposures in animal and cell culture models. Exercise, an essential stimulus for bone health, may exacerbate hypoxic stress; however, the skeletal response to acute hypoxic exposure combined with exercise remains unclear. We propose that intermittent exercise in hypoxia may increase negative markers …

Ultrasound-Derived Liver Composition And Metabolic Flexibility Under Exercise Stress, Rhodes Van Houten

All Master's Theses

Metabolic Associated Fatty Liver Disease (MAFLD) is characterized by abnormal liver fat accumulation in conjunction with metabolic syndromes. MAFLD affects 33% of individuals worldwide, though little is known about how increased liver fat impacts physiological responses to exercise. This study aimed to analyze the relationship between liver composition and metabolic flexibility during a graded exercise test.  Body composition was analyzed via dual-energy X-ray absorptiometry. Liver ultrasound was evaluated for echogenicity, where elevated mean gray volume (MGV) indicates abnormal liver tissue. Rates of fat (FATox) and carbohydrate (CHOox) oxidation (g/min), respiratory exchange ratio (RER), and blood lactate concentrations ([LA^-], …

24-H Circadian Rest-Activity Rhythms And Physical Frailty In Older Adults: A Biopsychosocial Perspective On Sex Differences And Social Capital, Jisu Kim

Theses and Dissertations

Physical frailty is a prevalent geriatric syndrome characterized by age-related decline across multiple physiological systems. Physical frailty is associated with an elevated risk of adverse health outcomes, including chronic disease progression and all-cause mortality, representing a significant and growing public health concern. Disrupted circadian rest-activity rhythms (RARs) are increasingly recognized as clinically meaningful markers of physical frailty in older adults. However, the extent to which biological sex and social determinants of health (SDoH), particularly social capital, contribute to or modify the associations between RARs and physical frailty remains underexplored.

Therefore, this dissertation summarizes the existing literature on age-related changes in …

Hydration Strategies In Ultra-Endurance Running: A Narrative Review Of Programmed Versus Thirst-Driven Approaches, Shawn C. Wierick, Rosie I. Perez, Xiujing Zhao, Brendon P. Mcdermott

Health, Human Performance and Recreation Faculty Publications and Presentations

Background/Objectives: Ultra-endurance running (UER) presents unique hydration challenges due to prolonged duration, variable terrain, environmental extremes, and gastrointestinal limitations.

This review examines the effectiveness and limitations of each strategy in the context of UER performance and safety. Methods: A narrative review was conducted using a targeted selection of peer-reviewed studies. Both laboratory- and field-based research were included to evaluate the physiological rationale, practical feasibility, and outcomes associated with PFI and TDFI. A total …

Optimizing Hip And Knee Assistance For Walking And Sit-To-Stand Transitions: An Intrinsic Muscle Mechanics Based Predictive Approach, Neethan Ratnakumar

Dissertations

As the global population ages, the demand for wearable assistive technologies continues to rise, driven by their potential to enhance mobility and independence in older adults. Effectively designed controllers for lower-limb exoskeletons to assist sit-to-stand (STS) and walking are crucial for delivering efficient, safe, and comfortable assistance during daily activities. Traditionally, controller optimization involves biomechanical modeling and user-specific customization. Musculoskeletal simulations play a central role in this process by providing insights into human-exoskeleton interaction dynamics, thereby informing and refining control strategies.

This work presents a simulation-driven approach for developing exoskeleton controllers for walking and STS using two distinct methods: optimal …

A Pilot Study Exploring Vitamin D, Mental Health, And Gastrointestinal Health In Humans, Brianna C. Williams

Master's Theses

Mental disorders are experienced by nearly one billion people worldwide. Depression is one of the most common. Treatments exist, yet a devastating 75% of individuals suffering from depression do not receive adequate treatment. An emerging treatment strategy includes exploring the connection between mental health and nutrition, which includes the areas of gut health and nutrient deficiencies. Vitamin D is obtained through food, supplements, and sunlight. Many individuals are considered deficient (25[OH]D concentrations < 12 ng/mL) or insufficient (25[OH]D concentrations < 20 ng/mL). Purpose: This study aimed to explore mental and gastrointestinal (GI) health using surveys and lipopolysaccharide binding protein (LBP) concentrations, a biomarker of GI health, in individuals considered 25(OH)D deficient (DEF) vs not deficient (N-DEF). Methods: This cross-sectional study recruited physically active participants aged 18-45 years who underwent three evaluations in one visit. Health was assessed using surveys to evaluate mental health, GI symptoms, and vitamin D intake. Serum from fasting blood samples was used with an enzyme-linked immunosorbent assay to determine 25(OH)D and LBP concentrations. Unpaired t-tests were used to compare DEF vs N-DEF and significance was set at p < 0.05. Results: Thirty-two participants (mean age 25.3 ± 6.3 years) with mean and body fat percentage of 24.0% ± 10.7%, were placed into DEF (n=16) and N-DEF (n=16) categories. Interestingly, five of the 16 participants in DEF (31%) showed some level of depression (scores ranging from mild to severe) and only two of the 16 participants in N-DEF iv (13%) scored positively in the depression category (scores ranging from mild to moderate). Additionally, the participant with the lowest 25(OH)D concentration (5.42 ng/mL) was the only participant to meet the “severe” depression category criteria, with a score of 24 compared to other participants who scored within 0-16. Also, the only participant who scored “severe” in the stress category, was in the bottom 20% of 25(OH)D concentrations. As for GI health, the difference between average GI scores and average serum LBP concentrations between the groups were not statistically significant. Conclusion: There were no significant differences between DEF and N-DEF in perceived depression (p = 0.16), anxiety (p = 1.0), stress (p = 0.96), GI symptoms (P values ranged from 0.27 to 1.00), nor in LBP concentrations (p = 0.77). Funding: Support was received from the Graduate Student Association and College of Natural Health Sciences at the University of Northern Colorado.

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 …

International Journal of Exercise Science

International Journal of Exercise Science 18(2): 107-118, 2025. Adipose tissue stores energy in fat-rich adipocytes, which can produce and release several adipokines and modulate body metabolism. Exercise may induce adipokine production in adipocytes; however, the relationship between the two remains unclear. Few studies have shown the relationship between adipokines and strength training. Thus, we aimed to evaluate the acute and chronic effects of strength training (ST) on urinary adiponectin, leptin, and resistin levels. Twelve untrained young men (23.42 ± 2.67 years) were included in this study. Body composition was evaluated at baseline and after completing of the training protocol using …

Female recreational runners (n=485) completed …

Investigating The Effects Of Visual Feedback On Muscle Activity, Heart Rate, Rpe, And Perceptions Of Performance In Ballet Dancers, Lilah A. Duboff, Sarah Dipasquale, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 17(1): 1056-1067, 2024. Extreme postures and imbalances in neuromuscular activity may place classical ballet dancers at higher risk of injury. Dance studio mirrors provide visual feedback by which a dancer can self-correct their body position and alignment, but have been suggested to negatively impact kinesthetic abilities and decrease performance capabilities. Thus, we investigated the effects of a mirror on muscle activity of the quadriceps, heart rate (HR), rating of perceived exertion (RPE), and qualitative performance. A lack of visual feedback would increase muscle activity of the quadriceps, HR, and RPE, and decrease self-reported perception of …

Quantifying Non-Gaussian Intermittent Fluctuations In Physiology: Multiscale Probability Density Function Analysis Using The Savitzky-Golay Detrending, Madhur Mangalam, Damian G. Kelty-Stephen, Eiichi Watanabe, Ken Kiyono

Journal Articles

When measuring physiological data, the central limit theorem typically implies a consistent variance, resulting in data that closely follow a Gaussian distribution. However, physiological measurements often deviate from this expectation, increasing variance due to nonlinear correlations across various scales. The challenge lies in testing these tails, which comprise only rare and extreme values. We introduce multiscale probability density function (PDF) analysis, a method that estimates this non-Gaussianity parameter for physiological fluctuations in each of multiple timescales. We gain valuable insights into the observed distributions with heavier tails and nonlinear correlations by exploring the relationship between non-Gaussianity and logarithmic scale. To …

The Acute Impacts Of Resistance Training Performed With And Without Blood Flow Restriction On Lower Body Muscular Power, Justin Faller, Brian Thompson, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 16(6): 1320-1333, 2023. The American College of Sports Medicine recommends resistance training using at least 70% one repetition maximum to improve muscular strength and hypertrophy; however, these intensities may not be safe for all populations. A training technique that has been reported to elicit increases in strength and muscle size uses low intensity resistance training or low load training in combination with blood flow restriction (BFR) to the working muscle. Although the acute effects of BFR on muscle strength and size are well established, the effects of BFR on muscular power are not definitively known. …

The Effects Of Accessory Blood Flow Restriction Training On Muscle Size And Strength In Division Iii Soccer Athletes: A Preliminary Ecological Study, Kaitlyn Judd, Christian Morales, Megan White, Kate Wilkie, Justin Faller, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 16(6): 1244-1256, 2023. Blood flow restriction training (BFRT) uses occlusion during low-intensity resistance training (< 50% of 1-repetition maximum, 1RM) to reduce arterial blood flow and venous return, imposing greater metabolic stress but similar muscular hypertrophy and strength gains as high-intensity resistance training (HIRT). However, no study, to date, has incorporated BFRT in a collegiate strength and conditioning setting to assess ecological validity. We aimed to investigate the effects of adding 6-weeks of accessory BFRT or HIRT to NCAA Division III soccer players prescribed resistance training regimen on muscle strength and size. Male and female (n = 17) athletes were randomly assigned to complete biceps curls 2x/week under BFRT or control (HIRT), following regularly scheduled strength training. Bicep strength (1RM) and circumference (BC) were assessed at weeks 0, 3, and 6 (men only). In men, for BC no significant interaction of condition x time was observed (p = 0.861), though condition (BFRT vs Control, p = 0.025) and time (p = 0.024) were significant. For 1RM, there was no significant interaction of condition …

Association Between Objectively-Measured Sedentary Time And Self-Reported Prescription Medication Use Among Adults: A Pilot Study, Ciarra Ashley Boyne

UNF Graduate Theses and Dissertations

BACKGROUND: Prescription medication use and extended sedentary time are independently related to poor health outcomes (e.g., diabetes, metabolic syndrome, mortality). Historically, survey methods have been used to obtain estimates of total sedentary time (ST), however, recent use of accelerometers avoids self-report bias and affords more characteristics of ST that may be factors in health outcomes (e.g., frequency and duration of sedentary bouts). The aims of this pilot study were to 1) examine the association between objectively measured ST via accelerometers and self-reported prescription medication use in adults and 2) examine the independent association of sedentary bout length and frequency with …

The Effects Of Cannabidiol Cream On Soreness And Performance After Exercise In Untrained Individuals, Joseph Thomas Pastina

Theses and Dissertations--Kinesiology and Health Promotion

Impairments associated with EIMD and DOMS can result in moderate-to-severe discomfort and hindered performance. Recently, a compound derived from the cannabis plant, cannabidiol (CBD), has been used as a recovery tool for EIMD and DOMS. Despite the rising popularity of CBD products, their effectiveness in mitigating EIMD and DOMS is unknown. Purpose: The purpose of the present study was to investigate the effects of CBD cream on DOMS and performance after an intensive lower-body exercise protocol. In addition, the study sought to …

Reliability And Validity Of A Commercial Running Power Meter To Indicate Metabolic Workload During Endurance Running, James Harris Hudgins Iii

Theses and Dissertations--Kinesiology and Health Promotion

Commercial running power (RP) meters may provide endurance runners and coaches with improved precision for monitoring running intensity. Cyclists rely upon the relationship between cycling power and metabolic demand to regulate physiological intensity during training and racing, independent of changes in the physical environment (e.g., terrain, wind). Research demonstrates strong reliability and validity for a specific RP meter to indicate metabolic demand within controlled running conditions. However, several potential influences on this relationship have not been investigated. Therefore, four studies were conducted with the following aims:

- Study 1: Determine the inter-limb reliability and validity of a single-limb-based RP meter …
