Variances In Power Output Of Female Athletes During The Menstrual Phases, Julia L. Allen

Masters Theses

The purpose of this research was to examine if there are any variances in a female athlete’s ability to produce power, that could be correlated with the menstrual cycle phases. The study observed three elite female athletes throughout 13 weeks, collecting relative propulsive power and relative braking power data from their vertical jump performances which occurred multiple times a week. At the end of the 13 weeks, participating athletes were asked to download their personal Oura Ring data. The Oura data points included in this study were used to identify and measure several physiological factors such as menstrual cycle day, …

Low Energy Availability (Lea) And Its Relationship To Nutritional Status And Bone Health In Collegiate Athletes, Anthony Dempsey

UNH URC Open (2026 and after)

This project aims to identify low energy availability in a sample of collegiate athletes and explore the relationship with bone mineral density and nutrient deficiencies. Participants (n=3,407) were recruited from a northeast university and self-reported athlete status and physical activity via online questionnaire. Food records were used to calculate energy and nutrient intake. Anthropometrics including height, weight, body composition and bone mineral status were measured in duplicate. Energy availability (EA) was calculated as (Energy Intake (EI) -Exercising Energy Expenditure) (EEE)) /Fat Free Mass (FFM) (kg) and categorized as optimal (>45 kcal/kg FFM), subclinical, or clinically low (< 30 kcal/kg FFM). Fifteen percent of participants were characterized as athletes (club or division I varsity); mean EA was lower among athletes vs. nonathletes (17.90.7vs.21.90.3, p< .001). Males were more likely to have optimal EA status vs. females (8.8vs4.7%, p< .001). Most females (75.1%) were categorized as clinically LEA; 20.3% had subclinical LEA. Among men, athletes’ EA was similar to nonathletes (21.11.2vs22.20.5, p=.4); among females, athletes had lower EA vs. nonathletes (16.220.9vs21.70.3, p< .001). Males with clinically low EA were most likely to consume inadequate intakes of potassium, fiber, iron, and vitamin D (77.1,94.0,10.4 and 97.3%, respectively); similarly, females with clinically low EA, were most likely to consume inadequate intakes (81.9,87.6,88.3, and 99.5%, respectively). Bone z-scores were higher among athletes vs. non athletes (-.27±.06vs-.67±.02, p< .001) but were not different by EA status. Given the prevalence of LEA within the college athlete and nonathlete populations, further research and tailored nutritional education is needed for this at-risk population.

The Impact Of Heavy Resistance Training On Type Ii Muscle Fibers Throughout Female Reproductive Stages, Lily G. Colberg

Scripps Senior Theses

Type II muscle fibers, also known as fast-twitch muscle fibers, are reliant on aerobic glycolysis and are crucial for high-force contractions, mobility, and rapid movements, such as fast reflexes. Heavy resistance training has been found to increase type II muscle fiber concentration in young, middle-aged, and elderly individuals. However, there have been few studies conducted on female-only sample populations. In women, the impact of heavy resistance training on type II muscle fibers is affected by the progressive decline of estrogen that defines the transition throughout the four female reproductive stages: premenopause, perimenopause, late-transition menopause, and postmenopause. Menopausal estrogen depletion causes …

Examining Weight Related Attitudes And Health Behaviors Among College Students, Alexis C. Denski

Senior Honors Theses and Projects

BACKGROUND: College is a pivotal period for the development of lifelong health behaviors. Factors such as greater personal freedom, poor diet, social norms, and insufficient physical activity (PA) contribute to common weight gain and increase of body image challenges. Although many college students report trying to lose weight, there is limited research examining if their PA and dietary behaviors align with evidence-based health recommendations. PURPOSE: Examine the proportion of college students trying to change their weight and their engagement in weight-related behaviors such as PA, strength training (ST), and dietary factors. METHODS: In Fall 2019, a random sample of 5,000 …

Using the push–pull framework and an ecological perspective, it explores how individual aspirations, family priorities, institutional resources, and national policies shape transnational mobility. Semistructured focus group discussions with 10 athletes and eight parents revealed six key motivational themes and highlighted the influence of recent collegiate sport-related policy changes in China. The findings suggest that while both groups value U.S. sport pathways, athletes and parents may …

I Want To Be The Very Best: Are Gamified Applications Like Pokémon Go Associated With Positive Health Outcomes?, Derek D. Mesa

Master's Theses or Doctor of Nursing Practice

Physical activity is a significant problem facing the United States, which can be associated with several negative health outcomes. Poor physical health and poor mental well-being are two outcomes that are often examined by researchers alongside reported physical activity. With the introduction of more advanced technology, interventions such as gamification can be made widely available to diverse groups. Gamification is the use of game-like elements in non-game environments, such as physical activity and health improvement. To determine if gamification has an association with the domains of physical activity, mental well-being, and physical health, this study employed a cross-sectional mixed methods …

Comparing Strength Testing Measures And The Association Of Strength And Body Composition In Young Children, Abigayle R. Spong

Theses and Dissertations--Kinesiology and Health Promotion

Muscle strength is an important component of physical fitness; however, measuring it with isokinetic dynamometry (IKD) is expensive and requires dedicated space. Handheld dynamometry (HHD) provides a practical alternative for field and clinical settings. Thus, the purpose of this study was to compare peak knee flexion and extension torque measured by IKD and HHD in 37 children (ages 5-11 years) and examine relationships with body composition. Participants completed a RAMPing protocol at 90^o knee flexion consisting of two warm-up contractions at 50% and 75% effort followed by three maximal voluntary isometric contractions. Body composition was assessed via DXA scans. …

Independent And Interactive Effects Of Stack Height And Heel Width On Spatiotemporal Parameters, Knee Joint Kinetics, And Ground Reaction Forces During Running, Hao Cai

College of Graduate Studies: Theses & Dissertations

This study investigated the independent and interactive effects of stack height (SH) and heel width (HW) on lower-extremity biomechanics during running. Specifically, the study examined how variations in midsole geometry influenced spatiotemporal parameters, knee joint kinetics, and ground reaction forces (GRF). Twelve recreational runners (8 males, 4 females) completed treadmill running trials at 16 km/h under nine shoe conditions that systematically varied in SH (25, 45, and 65 mm) and HW (81, 93, and 105 mm). Lower-extremity kinematics were collected using a Theia3D markerless motion capture system, and GRF data were recorded using an instrumented treadmill. A two-way repeated-measures ANOVA …

Comparison Of 2000-Meter Row Prediction To Measured Vo2peak During Gxt, Andrew S. Ashley

College of Graduate Studies: Theses & Dissertations

BACKGROUND: Aerobic capacity is essential for the performance of military personnel and first responders. Traditionally, graded exercise tests (GXTs) with metabolic gas analysis have been the criterion-referenced method for assessing aerobic fitness. However, treadmill running and cycle ergometers may not fully reflect the whole-body demands required in tactical environments. Rowing-based assessments and the currently commercially available VO2max prediction formula are widely used across tactical organizations as practical field measures, and most tactical operators are considered inexperienced rowers, which has been minimally examined. PURPOSE: The purpose of this study is to compare measured VO2peak from a rowing GXT with estimated VO2max …

Acute Lower Leg Transcutaneous Electrical Nerve Stimulation Increases Leg Blood Flow And Exercise Capacity In Patients With Peripheral Arterial Disease, Thomas K. Pellinger, Catherine B. Neighbors, Joshua C. Hefta, Patrick H. Luo, Carl B. Suarez, Erotokritos T. Varlas, Grant H. Simmons, Brett J. Wong

EVMS School of Health Professions Faculty Publications

We tested the hypothesis that two different durations of lower leg transcutaneous electrical nerve stimulation (TENS) increase post-TENS popliteal artery blood flow (PABF), popliteal vascular conductance (PVC), and 6-min walk distance (6MWD) in patients with peripheral artery disease (PAD). Seven subjects (5 male, 2 female) with PAD (67.9 ± 7.4 years; claudication: ankle-brachial index (ABI) < 0.90) participated in three randomized treatment sessions: control or bilateral TENS (3.0 Hz burst mode, 250 µs) for either 15 or 45 min. PABF (Doppler ultrasound) was measured before and after treatment. 6MWD and time/distance to claudication onset were measured 25 min post-treatment during each session. PABF, PVC and 6MWD increased after both 15 and 45 min of TENS (P < 0.05, post-TENS vs. pre-TENS baseline/control). Our preliminary results suggest that as little as 15 min of lower leg TENS increases leg blood flow and exercise capacity in individuals with PAD.

Felt Ambivalence Weakens The Attitude-Intention Pathway For Regular Leisure-Time Physical Activity In Chinese Adolescents: A Three-Wavee Prospective Study, Yaogang Han, Yubing Wang, Pan Li, Guohua Zheng

Human Movement Studies & Special Education Faculty Publications

Background: Favorable attitudes toward regular leisure-time physical activity may not always translate into intention if adolescents feel ambivalent about the behavior. This study tested whether felt ambivalence weakens the prospective attitude–intention association and the indirect effect of attitude on later behavior through intention. Methods: Chinese adolescents (N = 1714; Grades 7–12; mean age = 15.0 years) completed a three-wave survey at approximately two-week intervals. Wave 1 assessed attitudes toward regular leisure-time moderate-to-vigorous physical activity, felt ambivalence, and physical activity habit; Wave 2 assessed intention; and Wave 3 assessed leisure-time physical activity. Moderated mediation was tested in a structural equation model …

From Intention To Enactment: Action Planning And Habit Automaticity Distinguish Successful From Unsuccessful Intenders To Engage In Regular Leisure-Time Moderate-To-Vigorous Physical Activity, Yaogang Han, Yubing Wang, Pan Li, Binn Zhang

Human Movement Studies & Special Education Faculty Publications

University students often intend to exercise regularly but fail to translate intention into action. The present study tested which post-intentional processes distinguish successful from unsuccessful intenders in self-reported regular leisure-time moderate-to-vigorous physical activity (MVPA) enactment. Chinese undergraduates from 10 universities completed a three-wave survey administered at roughly two-week intervals. Habit automaticity was assessed at Wave 1, intention together with action planning and coping planning at Wave 2, and self-reported regular-exercise status at Wave 3. Because the dependent variable was assessed using a single stage-based self-report item, the findings should be interpreted as explaining self-reported regular-exercise status rather than objectively measured …

The Relationship Between Physical Activity, Sleep, And Hallucinations In Adults With Charles Bonnet Syndrome, Jarrod Hollis, Rohit Narayan, Eldre W. Beukes, Rosie Lindsay, Aliyah Bharwani, Umair Mughal, Ikra Yaqoob, Justin A. Haegele, Scott Muriden, Peter M. Allen

Human Movement Studies & Special Education Faculty Publications

Physical activity levels, hallucination experiences, sleep quality, and perceived stress were assessed using a survey administered to 57 adults with a confirmed diagnosis of Charles Bonnet Syndrome (CBS). Physical activity demonstrated a significant negative correlation with hallucination severity (r = –0.335, p = 0.011, two-tailed). A significant negative correlation was also observed between physical activity and perceived stress (r = –0.497, p < 0.001, two-tailed). In contrast, no significant association was identified between hallucination frequency and sleep disruption or insomnia. These findings suggest that engaging in appropriate levels of physical activity may help reduce the severity of hallucinations and mitigate stress among individuals with CBS. The observation that higher levels of physical activity are associated with reduced hallucination burden may help the development of evidence-based management strategies for CBS. Additionally, the finding that physical activity was significantly related to hallucination severity, whereas sleep disruption was not, merits deeper exploration in future research.

When Price Varies Across Otas: How Room Rate Disparity Shapes Switching Behavior And Brand Trust, Ling Ling, Chich-Chien Chen, Zvi Schwartz

Human Movement Studies & Special Education Faculty Publications

This study investigates how room rate disparity across Online Travel Agencies (OTAs) influences consumers’ switching behavior and perceptions of hotel brand integrity. Employing a scenario-based experimental design with a sample of 430 Chinese consumers, we explored price differences interact with loyalty status, price trajectory information, and brand consistency. Our findings reveal a complex non-linear inverse sigmoid relationship between rate disparity and channel switching. Contrary to expectations, loyalty membership did not reduce switching intent or increase discount thresholds. Moreover, rate disparity triggered brand integrity concerns, with brand doubt consistently exceeding switching intent. While price trajectory information did not change switching likelihood, …

Decreased Exercise-Induced Pulmonary Capillary Recruitment In Pulmonary Arterial Hypertension, David Langleben, Stylianos E. Orfanos, Benjamin D. Fox, Michele Giovinazzo, Magali Kaddis, John D. Catravas

Bioelectrics Publications

The human lung normally accommodates exercise-induced cardiac output increases mainly via recruitment of non-concomitantly perfused pulmonary capillaries. Recruitment is detectable by measuring the first-pass transpulmonary metabolism of ³H-benzoyl-Phe-Ala-Pro, providing an estimate of functional capillary surface area (FCSA). Pulmonary arterial hypertension (PAH) results from luminal narrowing of small precapillary arterioles, reducing downstream perfused FCSA. We hypothesized that exercising PAH patients would not be able to recruit FCSA normally. We studied two patients with severe PAH. Despite exercising to maximal dyspnea, neither could recruit FCSA. These limited data are the first direct measurements of FCSA in exercising PAH patients.
