    A Six-Year Retrospective of ePortfolio Implementation: Discovering Inclusion through Student Voice and Choice
    (WAC Clearinghouse, 2024) Urtel, Mark; Fallowfield, Stephen M.; Angermeier, Lisa; Swinford, Rachel; Exercise & Kinesiology, School of Health and Human Sciences
    Designing then implementing ePortfolios as a High Impact Practice (HIP) (Watson et al., 2016) across an academic program in kinesiology presents many opportunities and challenges. The authors document their six-year journey and ensuing lessons along the way, as they strive to uncover and enact best practices for department-wide implementation. After a first attempt implementing the ePortfolio when they realized their efforts fell short, this faculty team immersed themselves in comprehensive professional development and worked together with students to recast how each knew and understood an ePortfolio. To achieve the newly crafted outcomes of an ePortfolio project, the authors found that promoting student voice and choice is essential to fostering student engagement and inclusivity. Informed by findings of a mixed methods study, the faculty team hopes to provide a meaningful perspective that supports faculty exploration within ePortfolios and offer guidance to be sure students are partners in this journey.

    Academy of Geriatric Physical Therapy Research Agenda: Rationale for the Development and the Intent for Use
    (APTA Geriatrics, 2022-04) VanSwearingen, Jessie; Knox, Sara; Lowry, Kristin A.; Allison, Leslie K.; Ciolek , Cathy; Miller, Kenneth L.; Avin, Keith G.; Hartley, Greg W.; Exercise & Kinesiology, School of Health and Human Sciences
    The rationale for the development and the intent for use of a research agenda for the Academy of Geriatric Physical Therapy is described. The reasons for the research agenda for geriatric physical therapy are (1) to have a broad representation of the research conducted by physical therapist(s) working with older adults, (2) to provide guidance and assistance to emerging investigators to aid the trajectory of a research career, and (3) as a document to engage potential funding agencies, foundations, and individuals in support of physical therapist-conducted research. The design was based on the Research Agenda for Physical Therapy (APTA document), formatted to be consistent with the World Health Organization International Classification of Functioning, Disability and Health, priority ratings for the research statements, and specific examples of research questions for each category of the Research Agenda. The Academy of Geriatric Physical Therapy Research Agenda generated to be a living document, with revisions to research questions and priority ratings expected in the future to enable the agenda to adapt to changes in science, practice, workforce, education, and health policy.

    Adapted Dance and Individuals With Down Syndrome: A Phenomenological Approach
    (Sagamore, 2022-06-01) Swinford, Rachel; Noerr, Kyra; Exercise & Kinesiology, School of Health and Human Sciences
    Individuals with Down syndrome (DS) often experience lower levels of physical activity (PA) and social participation when compared to peers without DS. The purpose was to examine the lived experience of participating in the dance program and interpret the meaning of the dance program. Dancers participated in a 6-week adapted dance program and were interviewed after the program. This study investigated the lived experience of a 6-week adapted dance program for 20 individuals with Down syndrome (DS) using interpretive phenomenology. Dancer interviews revealed a primary theme of dancers experiencing joy and happiness while dancing. This research helps advocate opportunities for individuals with DS to experience dance as a social, physical, and intellectual activity. Findings can support future PA and sports initiatives for individuals with intellectual disabilities.

    Altered skeletal muscle metabolic pathways, age, systemic inflammation, and low cardiorespiratory fitness associate with improvements in disease activity following high-intensity interval training in persons with rheumatoid arthritis
    (BMC, 2021-07-10) Andonian, Brian J.; Johannemann, Andrew; Hubal, Monica J.; Pober, David M.; Koss, Alec; Kraus, William E.; Bartlett, David B.; Huffman, Kim M.; Exercise & Kinesiology, School of Health and Human Sciences
    Background: Exercise training, including high-intensity interval training (HIIT), improves rheumatoid arthritis (RA) inflammatory disease activity via unclear mechanisms. Because exercise requires skeletal muscle, skeletal muscle molecular pathways may contribute. The purpose of this study was to identify connections between skeletal muscle molecular pathways, RA disease activity, and RA disease activity improvements following HIIT. Methods: RA disease activity assessments and vastus lateralis skeletal muscle biopsies were performed in two separate cohorts of persons with established, seropositive, and/or erosive RA. Body composition and objective physical activity assessments were also performed in both the cross-sectional cohort and the longitudinal group before and after 10 weeks of HIIT. Baseline clinical assessments and muscle RNA gene expression were correlated with RA disease activity score in 28 joints (DAS-28) and DAS-28 improvements following HIIT. Skeletal muscle gene expression changes with HIIT were evaluated using analysis of covariance and biological pathway analysis. Results: RA inflammatory disease activity was associated with greater amounts of intramuscular adiposity and less vigorous aerobic exercise (both p < 0.05). HIIT-induced disease activity improvements were greatest in those with an older age, elevated erythrocyte sedimentation rate, low cardiorespiratory fitness, and a skeletal muscle molecular profile indicative of altered metabolic pathways (p < 0.05 for all). Specifically, disease activity improvements were linked to baseline expression of RA skeletal muscle genes with cellular functions to (1) increase amino acid catabolism and interconversion (GLDC, BCKDHB, AASS, PYCR, RPL15), (2) increase glycolytic lactate production (AGL, PDK2, LDHB, HIF1A), and (3) reduce oxidative metabolism via altered beta-oxidation (PXMP2, ACSS2), TCA cycle flux (OGDH, SUCLA2, MDH1B), and electron transport chain complex I function (NDUFV3). The muscle mitochondrial glycine cleavage system (GCS) was identified as critically involved in RA disease activity improvements given upregulation of multiple GCS genes at baseline, while GLDC was significantly downregulated following HIIT. Conclusion: In the absence of physical activity, RA inflammatory disease activity is associated with transcriptional remodeling of skeletal muscle metabolism. Following exercise training, the greatest improvements in disease activity occur in older, more inflamed, and less fit persons with RA. These exercise training-induced immunomodulatory changes may occur via reprogramming muscle bioenergetic and amino acid/protein homeostatic pathways.

    Angiogenic potential of skeletal muscle derived extracellular vesicles differs between oxidative and glycolytic muscle tissue in mice
    (Nature, 2023-11) Kargl, Christopher K.; Jia, Zhihao; Shera, Deborah A.; Sullivan, Brian P.; Burton, Lundon C.; Kim, Kun Ho; Nie, Yaohui; Hubal, Monica J.; Shannahan, Jonathan H.; Kuang, Shihuan; Gavin, Timothy P.; Exercise & Kinesiology, School of Health and Human Sciences
    Skeletal muscle fibers regulate surrounding endothelial cells (EC) via secretion of numerous angiogenic factors, including extracellular vesicles (SkM-EV). Muscle fibers are broadly classified as oxidative (OXI) or glycolytic (GLY) depending on their metabolic characteristics. OXI fibers secrete more pro-angiogenic factors and have greater capillary densities than GLY fibers. OXI muscle secretes more EV than GLY, however it is unknown whether muscle metabolic characteristics regulate EV contents and signaling potential. EVs were isolated from primarily oxidative or glycolytic muscle tissue from mice. MicroRNA (miR) contents were determined and endothelial cells were treated with OXI- and GLY-EV to investigate angiogenic signaling potential. There were considerable differences in miR contents between OXI- and GLY-EV and pathway analysis identified that OXI-EV miR were predicted to positively regulate multiple endothelial-specific pathways, compared to GLY-EV. OXI-EV improved in vitro angiogenesis, which may have been mediated through nitric oxide synthase (NOS) related pathways, as treatment of endothelial cells with a non-selective NOS inhibitor abolished the angiogenic benefits of OXI-EV. This is the first report to show widespread differences in miR contents between SkM-EV isolated from metabolically different muscle tissue and the first to demonstrate that oxidative muscle tissue secretes EV with greater angiogenic signaling potential than glycolytic muscle tissue.

    ARTE index revisited: linking biomarkers of cardiometabolic health with free-living physical activity in postmenopausal women
    (American Physiological Society, 2022-04-01) Carter, Stephen J.; Baranauskas, Marissa N.; Singh,, Harshvardhan; Martins, Catia; Hunter, Gary R.; Exercise & Kinesiology, School of Health and Human Sciences
    Activity-related energy expenditure (AEE) correlates with physical activity volume; however, between-person differences in body size and walking economy (net V̇o2) can influence AEE. The ratio of total energy expenditure (TEE) and resting energy expenditure (REE) estimates physical activity level (PAL) relative to body mass, yet does not account for variance in walking economy. The activity-related time equivalent (ARTEwalk) circumvents such constraints by adjusting for individual-specific walking economy. Herein, we compared AEE, PAL, and ARTEwalk index in a cohort (n = 81) of postmenopausal women while examining possible associations with biomarkers of cardiometabolic health. Secondary analyses were performed on postmenopausal women dichotomized above/below age group 50th percentile for body fat percent. TEE was reduced by 10% for the thermogenesis of digestion wherein AEE was calculated by subtracting REE from adjusted TEE. PAL was calculated as the ratio of TEE/REE. AEE was divided by the mean net energy expenditure of nongraded walking to calculate the ARTEwalk index. Between-group differences were not detected for AEE or PAL. However, the ARTEwalk index revealed that participants with less adiposity were more physically active (258 ± 149 vs. 198 ± 115 min·day−1; P = 0.046; g = 0.46). AEE and PAL did not correlate with cardiorespiratory fitness or biomarkers of cardiometabolic health. Cardiorespiratory fitness (r = 0.32), arterial elasticity (r = 0.24), total cholesterol/HDL-c ratio (r = −0.22), and body fat% (r = −0.24) were correlated with ARTEwalk. The ARTEwalk index may offer utility in detecting possible differences in physical activity volume among postmenopausal women and appears better associated with cardiometabolic biomarkers compared with AEE or PAL.

    Beetroot juice supplementation and exercise performance: is there more to the story than just nitrate?
    (Frontiers Media, 2024-02-20) Zoughaib, William S.; Fry, Madison J.; Singhal, Ahaan; Coggan, Andrew R.; Exercise & Kinesiology, School of Health and Human Sciences
    This mini-review summarizes the comparative effects of different sources of dietary nitrate (NO3-), beetroot juice (BRJ) and nitrate salts (NIT), on physiological function and exercise capacity. Our objectives were to determine whether BRJ is superior to NIT in enhancing exercise-related outcomes, and to explore the potential contribution of other putatively beneficial compounds in BRJ beyond NO3-. We conducted a comparative analysis of recent studies focused on the impact of BRJ versus NIT on submaximal oxygen consumption (VO2), endurance performance, adaptations to training, and recovery from muscle-damaging exercise. While both NO3- sources provide benefits, there is some evidence that BRJ may offer additional advantages, specifically in reducing VO2 during high-intensity exercise, magnifying performance improvements with training, and improving recovery post-exercise. These reported differences could be due to the hypothesized antioxidant and/or anti-inflammatory properties of BRJ resulting from the rich spectrum of phytonutrients it contains. However, significant limitations to published studies directly comparing BRJ and NIT make it quite challenging to draw any firm conclusions. We provide recommendations to help guide further research into the important question of whether there is more to the story of BRJ than just NO3-.

    COVID-19: Implications for Physical Activity, Health Disparities, and Health Equity
    (Sage, 2021-07-27) Hasson, Rebecca; Sallis, James F.; Coleman, Nailah; Kaushal, Navin; Nocera, Vincenzo G.; Keith, NiCole; Exercise & Kinesiology, School of Health and Human Sciences
    Physical activity is one of the most efficacious pathways to promoting mental and physical health, preventing disease, and, most important during the COVID-19 pandemic, bolstering a stronger immune system. Efforts to “flatten the curve” have resulted in the temporary closure of exercise facilities and gyms, suspension of sport activities, and advisories to avoid public recreational spaces. All of these changes have made traditional opportunities to be physically active difficult to access. These changes have also exacerbated existing disparities in access to social and environmental supports for physical activity, potentially contributing to a widening gap in physical activity participation among those at greatest risk for COVID-19. Physical activity can play a special role in reducing the inequitable consequences of COVID-19; however, expansion and better targeting of evidence-informed interventions are needed that address the unique barriers present in communities that have been economically and socially marginalized to achieve health equity in COVID-19 outcomes. This review highlights effective and feasible strategies that provide more equitable access to physical activity programs and spaces across the United States. With a renewed investment in physical activity, this behavior can play a crucial role in improving population health and reducing disparities during the COVID-19 pandemic and beyond.

    Effectiveness of biomedical interventions on the chronic stage of traumatic brain injury: a systematic review of randomized controlled trials
    (Frontiers Media, 2024-03-18) Kawata, Keisuke; Rettke, Devin J.; Thompson, Christopher; Mannix, Rebekah; Bazarian, Jeffrey J.; Datta, Dibyadyuti; Exercise & Kinesiology, School of Health and Human Sciences
    Traumatic brain injury (TBI), in any form and severity, can pose risks for developing chronic symptoms that can profoundly hinder patients’ work/academic, social, and personal lives. In the past 3 decades, a multitude of pharmacological, stimulation, and exercise-based interventions have been proposed to ameliorate symptoms, memory impairment, mental fatigue, and/or sleep disturbances. However, most research is preliminary, thus limited influence on clinical practice. This review aims to systematically appraise the evidence derived from randomized controlled trials (RCT) regarding the effectiveness of pharmacological, stimulation, and exercise-based interventions in treating chronic symptoms due to TBI. Our search results indicate that despite the largest volume of literature, pharmacological interventions, especially using neurostimulant medications to treat physical, cognitive, and mental fatigue, as well as daytime sleepiness, have yielded inconsistent results, such that some studies found improvements in fatigue (e.g., Modafinil, Armodafinil) while others failed to yield the improvements after the intervention. Conversely, brain stimulation techniques (e.g., transcranial magnetic stimulation, blue light therapy) and exercise interventions were effective in ameliorating mental health symptoms and cognition. However, given that most RCTs are equipped with small sample sizes, more high-quality, larger-scale RCTs is needed.
