Perceptions And Use Of The Athletic Training Milestones In Education: A Report From The Aate Research Network, Cailee E. Welch Bacon, Barton E. Anderson, Julie M. Cavallario, Bonnie L. Van Lunen, Lindsey E. Eberman

Clinical Practice in Athletic Training

The Athletic Training Milestones (AT Milestones) were developed as an evaluation tool to capture the breadth and depth of athletic training knowledge, skills, and behavior. However, it is unclear whether athletic training programs are implementing this tool or how they are implementing it to gauge the clinical progression of students or residents in athletic training. We aimed to explore the perceptions and use of the AT Milestones among educators in athletic training programs. We used a cross-sectional, web- based survey with open-ended questions to collect data from athletic training programs on if and how they implement the AT Milestones at …

Sensory Dysfunction And The Role Of Nrf2 In The Production Of Pain In Chronic Hindlimb Ischemia, Oliver Kitzerow

Theses & Dissertations

Peripheral arterial disease (PAD) is a progressive and debilitating atherothrombotic disorder that is estimated to impact >200 million people worldwide. Higher physical activity levels are associated with better overall survival rates, slower decline of functional capability, and improved quality of life. However, intermittent claudication, pain produced by physical activity, severely limits functional capacity in PAD patients. Despite known sensory dysfunction and documented neuropathy in diseased patients, the neural mechanisms that produce pain in PAD are yet to be identified. Importantly, few animal models of hindlimb ischemia (HLI) successfully recapitulate chronic human PAD. We developed a chronic animal model of HLI …

Resistance Training And Running Performance And Economy: A Literature Review, James Bottrill

University Honors Theses

Running performance is largely determined by maximal oxygen uptake (VO₂ max), velocity at VO₂ max, fractional utilisation of VO₂ max and running economy. Running economy is relatively under-researched and could be improved by resistance training because of its neuromuscular underpinnings. However, existing research on this topic is quite unorganised and inconclusive and is yet to prove a direct linkage between resistance training, running economy and performance. This literature review aimed to provide an organised overview of the existing literature, identify and address confounding variables and provide recommendations for future research. A search for studies was conducted via …

Ankle Dorsiflexion Range Of Motion, Dynamic Balance, And Static Balance In Division Iii Collegiate Gymnasts, Emily Sabo

Master's Theses

Introduction: Artistic gymnastics is a demanding sport composed of high intensity activities. Decreased range of motion can increase the risk of lower extremity injury due to the inability to disperse forces properly upon landing. Landing from a height demands dynamic balance, which may be influenced by ankle range of motion. Due to the complexity of the sport, identifying potential deficits at the ankle could lead to the development of injury prevention programs. Purpose: The purpose of this study is to investigate if correlations exist between active ankle dorsiflexion range of motion (AROM) and static balance and/or AROM and dynamic balance …

Purpose: Biased perceptions of individuals who are not part of one's in-groups tend to be negative and habitual. Because health care professionals are no less susceptible to biases than are others, the adverse impact of biases on marginalized populations in health care warrants continued attention and amelioration.Method: Two characters, a Syrian refugee with limited English proficiency and a black pregnant woman with a history of opioid use disorder, were developed for an online training simulation that includes an interactive life course experience focused on social determinants of health, and a clinical encounter in a community health center utilizing virtual reality …

A Literature Review On The Development Of Upper Limbs In Humans, Anh T. Phan

The Cardinal Edge

The development of tetrapod upper limbs shares an evolutionary origin and has been adapted and specialized for different functions for different species, such as flight in birds, swimming and balance in sea mammals, and coordination and grabbing objects in humans. The basis of tetrapod limb development has common developmental patterns, starting with the formation of the limb bud via Sonic hedgehog (Shh) signaling, where later developmental steps are modified for specialized functions. This review covers the basic developmental patterns of mammalian tetrapod development seen in humans, beginning with the formation of the limb bud, to the axis development of the …

A Systematic Review And Meta-Analysis On The Efficacy Of Stem Cell Therapy On Bone Brittleness In Mouse Models Of Osteogenesis Imperfecta, Lauren Battle, Shoshana Yakar, Alessandra Carriero

Publications and Research

There is no cure for osteogenesis imperfecta (OI), and current treatments can only partially correct the bone phenotype. Stem cell therapy holds potential to improve bone quality and quantity in OI. Here, we conduct a systematic review and meta-analysis of published studies to investigate the efficacy of stem cell therapy to rescue bone brittleness in mouse models of OI. Identified studies included bone marrow, mesenchymal stem cells, and human fetal stem cells. Effect size of fracture incidence, maximum load, stiffness, cortical thickness, bone volume fraction, and raw engraftment rates were pooled in a random-effects meta-analysis. Cell type, cell number, injection …

From Professor To Patient X, Anne R. Crecelius

Health and Sport Science Faculty Publications

I walked into the classroom feeling nervous. It wasn't my first time teaching undergraduate students about human endocrine physiology. I knew the material well. But today's lecture was different. I pulled up slides depicting a hypothetical cancer patient and told them, “Patient X had a biopsy that detected invasive carcinoma in her breast.” I described the many months of chemotherapy, surgery, and radiation treatments she went through before going into remission. Then I taught the students about the hormonal therapy she was prescribed—drugs her doctor hoped would limit the growth of any remaining cancer cells and prevent a recurrence. On …

The Effects Of Acute Exercise On Bone Turnover Markers In Middle-Aged And Older Adults: A Systematic Review, Cassandra Smith, Alexander Tacey, Jakub Mesinovic, David Scott, Xuzhu Lin, Tara C. Brennan-Speranza, Joshua R. Lewis, Gustavo Duque, Itamar Levinger

Research outputs 2014 to 2021

© 2020 Elsevier Inc. Background: Bone turnover is the cellular machinery responsible for bone integrity and strength and, in the clinical setting, it is assessed using bone turnover markers (BTMs). Acute exercise can induce mechanical stress on bone which is needed for bone remodelling, but to date, there are conflicting results in regards to the effects of varying mechanical stimuli on BTMs. Objectives: This systematic review examines the effects of acute aerobic, resistance and impact exercises on BTMs in middle and older-aged adults and examines whether the responses are determined by the exercise mode, intensity, age and sex. Methods: We …

Age And Sex Differences In Load-Induced Tibial Cortical Bone Surface Strain Maps, Alessandra Carriero, Behzad Javaheri, Neda Bassir Kazeruni, Andrew A. Pitsillides, Sandra J. Shefelbine

Publications and Research

Bone adapts its architecture to the applied load; however, it is still unclear how bone mechano-adaptation is coordinated and why potential for adaptation adjusts during the life course. Previous animal models have suggested strain as the mechanical stimulus for bone adaptation, but yet it is unknown how mouse cortical bone load-related strains vary with age and sex. In this study, full-field strain maps (at 1 N increments up to 12 N) on the bone surface were measured in young, adult, and old (aged 10, 22 weeks, and 20 months, respectively), male and female C57BL/6J mice with load applied using a …

Advising Physiology Students: Perceptions From The Programs, Anne R. Crecelius, Patrick L. Crosswhite

Health and Sport Science Faculty Publications

Academic advising outcomes can be linked to both student success and retention. Yet relatively little is known specifically related to advising in physiology programs. Pro- fessional organizations dedicated to academic advising in general, and more specifically advising future health professional students exist, yet, whether current physiology programs utilize these resources remains unknown, as does a number of other demographic informa- tion about advising in physiology programs. Here we present data gathered from a sample of physiology educators to inform what current advising practices of physiology students are. Forty-five re- spondents from a variety of institutions and programs provided information on …

The Case For Coordinating Efforts To Establish Program Guidelines And Strengthen Physiology Undergraduate Degree Programs, Erica A. Wehrwein, Lisa C. Anderson, Anne R. Crecelius, Claudia I. Stanescu, James M. Poteracki, John R. Halliwill, Nancy M. Aguilar-Roca, Jennifer Rogers

Health and Sport Science Faculty Publications

Undergraduate degree programs named “Physiology” have existed for over 50 yr. The number of programs and enrolled students have been growing since ~2005 (5, 9). There are many thousands of students currently enrolled in physiology pro- grams across the United States and indeed across the world. Despite the long history and current popularity of the physiol- ogy major, there is no coordinated plan articulated for the design, administration, or assessment of degree programs in physiology at the undergraduate level.

Although several professional societies have invested in under- graduate physiology education in various ways, none has under- taken the task of …

An Investigation Of Stress-Related Factors And Injury Occurrence In Division Iii Ice Hockey Athletes 2020., Christian Kiesel

Master's Theses

Many variables can factor into a student athlete sustaining an injury, but one of the most interesting is stress. The Stress and Injury Model is excellent in explaining how exactly history of stressors, personality, and coping mechanisms play a pivotal role in the stress response. If these three factors cause a negative stress response, then that will lead to an athlete becoming more likely to become injured. This study used 40 ice hockey players from a Division III NCAA institution. Each participant completed the Inventory of College Students’ Recent Life Experiences (ICSRLE) and Pittsburgh Sleep Quality Index (PSQI) every month …

A Comparison Of Power Variables For Two Loading Methods In Weighted Vertical Jumps 2020, Jonathan Tanguay

Master's Theses

Training exercises to develop muscular strength and power, such as the weighted jump squat, commonly utilize barbells and dumbbells to increase resistance. Strength coaches often measure improvements in peak force, peak power, and rate of force development to determine effectiveness of a training program. The purpose of this study was to determine if equipment selection (barbells vs. dumbbells) affects peak force, peak power, and/or rate of force development in weighted jump squats. Thirteen physically active, college-aged males (age: 21.6 ± 2.0 years, height: 182.8 ± 9.7 cm, body mass: 87.2 ± 9.0 kg, lean mass: 72.3 ± 8.1 kg) performed …

Life-Long Reduction In Myomir Expression Does Not Adversely Affect Skeletal Muscle Morphology, Ivan J. Vechetti Jr., Yuan Wen, Thomas Chaillou, Kevin A. Murach, Alexander Alimov, Vandre C. Figueiredo, Maeli Dal-Pai-Silva, John J. Mccarthy

Physiology Faculty Publications

We generated an inducible, skeletal muscle-specific Dicer knockout mouse to deplete microRNAs in adult skeletal muscle. Following tamoxifen treatment, Dicer mRNA expression was significantly decreased by 87%. Wild-type (WT) and Dicer knockout (KO) mice were subjected to either synergist ablation or hind limb suspension for two weeks. There was no difference in muscle weight with hypertrophy or atrophy between WT and KO groups; however, even with the significant loss of Dicer expression, myomiR (miR-1, -133a and -206) expression was only reduced by 38% on average. We next aged WT and KO mice for ~22 months following Dicer inactivation to determine …

Human Skeletal Muscle Macrophages Increase Following Cycle Training And Are Associated With Adaptations That May Facilitate Growth, R. Grace Walton, Kate Kosmac, Jyothi Mula, Christopher S. Fry, Bailey D. Peck, Jason S. Groshong, Brian S. Finlin, Beibei Zhu, Philip A. Kern, Charlotte A. Peterson

Center for Muscle Biology Faculty Publications

Skeletal muscle macrophages participate in repair and regeneration following injury. However, their role in physiological adaptations to exercise is unexplored. We determined whether endurance exercise training (EET) alters macrophage content and characteristics in response to resistance exercise (RE), and whether macrophages are associated with other exercise adaptations. Subjects provided vastus lateralis biopsies before and after one bout of RE, after 12 weeks of EET (cycling), and after a final bout of RE. M2 macrophages (CD11b+/CD206+) did not increase with RE, but increased in response to EET (P < 0.01). Increases in M2 macrophages were positively correlated with fiber hypertrophy (r = 0.49) and satellite cells (r = 0.47). M2c macrophages (CD206+/CD163+) also increased following EET (P < 0.001), and were associated with fiber hypertrophy (r = 0.64). Gene expression was quantified using NanoString. Following EET, the change in M2 macrophages was positively associated with changes in HGF, IGF1, and extracellular matrix genes. EET decreased expression of IL6 (P < 0.05), C/EBPβ (P < 0.01), and MuRF (P < 0.05), and increased expression of IL-4 (P < 0.01), TNFα (P < 0.01) and the TWEAK receptor FN14 (P < 0.05). The change in FN14 gene expression was inversely associated with changes in C/EBPβ (r = −0.58) and MuRF (r = −0.46) following EET. In cultured human myotubes, siRNA inhibition of FN14 increased expression of C/EBPβ (P < 0.05) and MuRF (P < 0.05). Our data suggest that macrophages contribute to the muscle response to EET, potentially including modulation of TWEAK-FN14 signaling.

Skeletal muscle comprises a family of diverse tissues with highly specialized functions. Many acquired diseases, including HIV and COPD, affect specific muscles while sparing others. Even monogenic muscular dystrophies selectively affect certain muscle groups. These observations suggest that factors intrinsic to muscle tissues influence their resistance to disease. Nevertheless, most studies have not addressed transcriptional diversity among skeletal muscles. Here we use RNAseq to profile mRNA expression in skeletal, smooth, and cardiac muscle tissues from mice and rats. Our data set, MuscleDB, reveals extensive transcriptional diversity, with greater than 50% of transcripts differentially expressed among skeletal muscle tissues. We detect …

Acute Resistance Exercise Induces Sestrin2 Phosphorylation And P62 Dephosphorylation In Human Skeletal Muscle, Nina Zeng, Randall F. D'Souza, Vandre C. Figueiredo, James F. Markworth, Llion A. Roberts, Jonathan M. Peake, Cameron J. Mitchell, David Cameron-Smith

Center for Muscle Biology Faculty Publications

Sestrins (1, 2, 3) are a family of stress-inducible proteins capable of attenuating oxidative stress, regulating metabolism, and stimulating autophagy. Sequestosome1 (p62) is also a stress-inducible multifunctional protein acting as a signaling hub for oxidative stress and selective autophagy. It is unclear whether Sestrin and p62^Ser403 are regulated acutely or chronically by resistance exercise (RE) or training (RT) in human skeletal muscle. Therefore, the acute and chronic effects of RE on Sestrin and p62 in human skeletal muscle were examined through two studies. In Study 1, nine active men (22.1 ± 2.2 years) performed a bout of single-leg strength …

Differential Requirement For Satellite Cells During Overload-Induced Muscle Hypertrophy In Growing Versus Mature Mice, Kevin A. Murach, Sarah H. White, Yuan Wen, Angel Ho, Esther E. Dupont-Versteegden, John J. Mccarthy, Charlotte A. Peterson

Physical Therapy Faculty Publications

Background: Pax7+ satellite cells are required for skeletal muscle fiber growth during post-natal development in mice. Satellite cell-mediated myonuclear accretion also appears to persist into early adulthood. Given the important role of satellite cells during muscle development, we hypothesized that the necessity of satellite cells for adaptation to an imposed hypertrophic stimulus depends on maturational age.

Methods: Pax7^CreER-R26R^DTA mice were treated for 5 days with vehicle (satellite cell-replete, SC+) or tamoxifen (satellite cell-depleted, SC-) at 2 months (young) and 4 months (mature) of age. Following a 2-week washout, mice were subjected to sham surgery or 10 day …
