Subsequently, 526 target users from University, Qualtrics and Prolific participant panels assessed exercise programs through an online survey. Dimensionality was assessed using Principal Component Analysis (PCA), Exploratory Factor Analysis (EFA), and bifactor models. …

Relationships Between Lower Body Anthropometrics And Vertical Force-Velocity Profiles In Collegiate American Football Players, Nicholus Adam Despot

Doctoral Dissertations and Projects

The study examined the relationships between lower-body anthropometric characteristics and vertical force-velocity profiles in collegiate American football players. Although the use of force-velocity profiling has increased significantly in recent years, there has been limited research on the association between structural features and key mechanical outputs. A sample of 16 NAIA football players was used to examine how skeletal breadths, girths, and derived ratios relate to key force-velocity metrics. Anthropometric variables were collected using ISAK standards, while force-velocity profiles were obtained through a series of loaded squat jumps on a force platform. Mean propulsive force, velocity and power were used to …

Deutz, Andrew T. Askow, Colleen F. Mckenna, Jonathan A. Aguilera, Cassidy T. Tinline-Goodfellow, Alexander V. Ulanov, Jared W. Willard, Daniel W. D. West, Michael De Lisio, Daniel R. Moore, Nicholas A. Burd

Kinesiology & Sport Management Scholarship

Excess adiposity is linked to anabolic resistance by blunting the postprandial myofibrillar protein synthetic response to protein ingestion. Full-fat dairy milk may overcome this resistance via a matrix combining high-quality protein with anti-inflammatory lipids. Therefore, we compared the effects of ingesting full-fat dairy milk versus a non-dairy macronutrient match isolated blend on the regulation of postprandial myofibrillar and mitochondrial protein synthesis rates and markers of systemic (i.e., IL-6 and TNF-α) and muscle-related inflammation (i.e., NF-κB, NLRP3, TLR4, and MyD88). Twenty-two obese and overweight adult males and females (BMI = 31.1 ± 3.7 kg m−2; aged 35.3 ± 13.2 y) were …

BACKGROUND: Cardiovascular disease (CVD) and Alzheimer's disease (AD) are major public health concerns that share overlapping risk factors and potential mechanistic pathways. Although vascular contributions to cognitive decline are well documented, the specific relationships between AD and different CVD subtypes remain poorly understood. METHODS: In this cross-sectional study, we examined associations between AD and 11 CVD subtypes using logistic regression models in 2 large biobanks: the UK Biobank (n=502 133) and the All of Us Research Program (n=287 011). Models were adjusted for demographic, lifestyle, and clinical covariates. We also explored genetic overlap between AD and CVD traits through proximity-based …

Shared Premotor Resources Underlie Dual-Task Interference Between Speech And Balance, Weina Lu, Sasha Lifton Lewis, Zoey Wire, Ingo Helmich

Exercise and Sport Studies: Faculty Publications

Humans frequently speak while standing, potentially engaging overlapping motor-cognitive resources. Dual-task paradigms with increased motor-cognitive demands reliably impair postural control, presumably due to competition for shared neural resources. The premotor cortex is critically involved in balance stabilization and in resolving competing motor plans and is also engaged during processing of action-related language. We therefore hypothesized that a central processing bottleneck emerges in the PMC when speaking and controlling posture simultaneously. Forty-one right-handed healthy adults (25 female, 16 male) maintained an upright stance while either verbally describing or mentally imagining navigation through a visually presented maze from an egocentric or allocentric …

Correlations Between The Army Combat Fitness Test (Aft) Events And The 12-Mile Ruck March, Isabella Huner Cruz

Masters Theses

The Army Fitness Test (AFT) consists of maximum deadlift, hand-release push-ups, sprint-drag-carry, plank, and a 2-mile run and is used by the United States Army to assess a soldier’s ability to meet occupational demands. The AFT is designed to ensure soldier readiness and maintain physical and mental well-being. In addition to the AFT, soldiers are often tasked with a loaded ruck march across various distances. Loaded ruck marches are a frequent occurrence in the Army as a mode of testing, training, and combat. Due to the AFT’s role in predicting soldier task performance, it would be valuable to identify any …

Michigan Tech Publications

Gynecological malignancies such as cancer of the cervix, ovary, endometrium, vulva, and vagina pose a severe global health burden. Although conventionally attributed to genetic mutation, hormonal imbalance, and chronic viral infection, including high-risk human papillomavirus, recent evidence suggests that the human microbiome plays a central role in their pathogenesis and development. This review summarizes existing evidence that microbial dysbiosis, specifically the depletion of beneficial Lactobacillus species and overrepresentation of anaerobic organisms such as Fusobacterium, Atopobium, and Sneathia, is implicated in carcinogenesis pathways. These include chronic inflammation, immune modulation, loss of epithelial barrier integrity, microbial metabolite toxicity, and estrogen metabolism by …

Expanding The Convergence Canon: Indigenous Knowledge Systems And Place-Based Convergence Research In Lake Superior’S Keweenaw Bay, Usa, Melissa Baird, Valoree Gagnon, Judith Perlinger, Noel Urban, Larissa A. Juip, Kelly Kamm, Evelyn Ravindran, Caren Ackley, Cassandra M. Reed-Vandam

Michigan Tech Publications

This study presents results from an NSF-funded convergence research project conducted in partnership with the Keweenaw Bay Indian Community (KBIC) in Michigan’s Upper Peninsula, USA. While convergence research frameworks often emphasize deep integration, we argue that participatory, place-based, and community-led convergence requires maintaining an integrity of difference. Through a systematic literature review, surveys and semi-structured interviews, we examined how team members operationalized convergence research and the Tribal Landscape System (TLS) framework. Across these data sources, convergence emerged as a negotiated practice shaped by distinct roles, institutional responsibilities, and long-term partnership commitments. Our findings demonstrate that ethical engagement, adaptive collaboration, and …

Psychosocial Mediators Of A Physical Activity And Dietary Intervention In Pregnant Women With Overweight Or Obesity, Meghan Baruth, Sarah Wilcox, Jihong Liu, Rebecca Schlaff

Faculty Publications

Background

Mediation analyses provide insight into both ‘pieces’ of the mediation chain; they allow us to look into the ‘black box’ that is behavior change. They allow researchers to better understand the ‘how’ of an intervention’s effects and/or the ‘why’ behind why an intervention worked or did not work. The lack of publications in pregnant populations highlights the need for additional studies to be conducted and published. The purpose of this study is to examine the psychosocial mediators of physical activity and dietary outcomes in a sample of pregnant women with overweight or obesity participating in the Health in Pregnancy …

School-based interventions aiming to increase children’s physical activity have largely been ineffective, perhaps due to a lack of consideration of the unique culture within each school. The aim of this paper is to understand the key aspects of physical activity culture in English primary schools using the organizational culture framework.

Methods: A four-month rapid ethnography study was conducted within three primary schools in Bristol, UK, between March and July 2024. The findings draw on observations, interviews, documentary data, photo elicitation, informal conversations and …

Gastrointestinal Symptoms After Sport-Related Concussion In Irish Athletes, Emma Finnegan, Ed Daly, Katherine Hunzinger, Lisa Ryan

Department of Exercise Science Faculty Papers

Background/Objectives: Sport-related concussion (SRC) elicits multi-systemic symptoms, including nausea, fatigue, and cognitive changes. Gastrointestinal (GI) symptoms are not well captured in current concussion assessments and may be under-recognised in clinical follow-up. GI disturbances may influence intake tolerance and day-to-day fuelling during post-SRC recovery. This study investigated the prevalence and severity of self-reported GI symptoms in Irish athletes after their most recent SRC, examined sex-based patterns, and evaluated the rationale for integrating GI symptom checks into standard concussion tools (e.g., SCAT6) and post-injury monitoring. Methods: An online survey was completed by recreational, competitive, and elite athletes who retrospectively self-reported concussion history, …

Biomechanical Characterization Of Porcine Lower Limb Arteries For Preclinical Evaluation Of Peripheral Vascular Devices, Barbara Batista De Oliveira, Frazer Heinis, Anastasia Desyatova, Jason Mactaggart, Alexey Kamenskiy

Journal Articles

Purpose Peripheral artery disease (PAD) predominantly affects the lower extremities, where complex biomechanical deformations during limb flexion contribute to disease progression and treatment failure. While human and cadaver studies have characterized these deformations, preclinical device testing requires large-animal models that replicate human arterial anatomy and biomechanics. Swine are commonly used, yet their biomechanical comparability to humans remains poorly defined. Methods We performed a detailed morphometric and biomechanical analysis of the external iliac (EIA), superficial femoral (SFA), and popliteal (PA) arteries in 20 Yucatan and 16 domestic swine using computed tomography angiography. Arteries were evaluated in straight and flexed limb postures …
