PURPOSE: To investigate the effect of unloading time on femoral cartilage thickness in active females for both knees. METHODS: 18 college aged (18-23 years old) physically active injury-free females laid supine on a padded plinth. Ultrasound images were collected for both knees …

The Gut Microbiome And How Adhd And Parkinson’S Disease May Be Linked, April Mccoy, Maria Bellumori

International Journal of Exercise Science: Conference Proceedings

There is growing interest in the gut microbiome and its effects on the central nervous system (CNS). Good bacteria in the gut play a role in neurotransmitter synthesis and regulation, which contributes to CNS control. Excess harmful bacteria may lead to leaky gut syndrome and neuroinflammation. Dysbiosis refers to a negative imbalance of the two types of bacteria and is associated with disease and decreased dopamine synthesis. Decreased dopamine, a neurotransmitter, plays a pivotal role in the manifestation of symptoms associated with attention-deficit/hyperactivity disorder (ADHD) and Parkinson's disease (PD). Previous studies have demonstrated a correlation between the gut microbiome and …

Is Ambulatory Blood Pressure A Good Predictor Of The Blood Pressure Response To Moderate-Intensity Exercise?, Braxton Bird, Jayson Gifford, Joseph Larsen

International Journal of Exercise Science: Conference Proceedings

Cardiovascular Disease (CVD) has been the leading cause of death in the United States since the 1920s. One of the most prominent precursors of CVD is high blood pressure (hypertension), which is commonly diagnosed by using the gold standard method of 24-hour blood pressure monitoring (ABPM). However, ABPM isn’t controlled throughout the day and is not very reproducible. Recently exercise systolic blood pressure (ExSBP) has received more attention since it is highly regulated and accurately represents cardiovascular strain during tasks of daily living. Purpose: The objective of this study is to determine whether ambulatory blood pressure could act as …

Blood Flow Observed In The Majority Of Gymnasts’ Achilles And Patellar Tendons Despite Their Years Of Experience, Kalissa Cox, Lee J Hinkle, Phillip Hartog, Bryson T. Schaugaard, Gabe Davidson, Aaron W. Johnson

International Journal of Exercise Science: Conference Proceedings

Gymnasts frequently suffer from tendinopathy. Additionally, time of participation in gymnastics may increase the risk of tendinopathy. Neovascularization is associated with tendinopathy of the body as it attempts to heal. Neovascularization of the Achilles and patellar tendons can be assessed using intra-tendinous Power Doppler Imaging (PDI) via ultrasound. Exercise and training increases blood flow; thus we sought to measure blood flow post-exercise when blood flow was potentially the highest. PURPOSE: The purpose of this study was to determine whether the gymnasts’ years of experience was associated with the blood flow to the Achilles and patellar tendons post-exercise. METHODS: Twenty-four female …

Effect Of Intranasal Insulin On Neurovascular Coupling In Healthy Young Adults, Brian Shariffi, Neil Mcmillan, Anna Gonsalves, Camila Manrique-Acevedo, Jaume Padilla, Jacqueline Limberg

International Journal of Exercise Science: Conference Proceedings

ABSTRACT

Emerging evidence supports an essential role for insulin signaling in neurovascular coupling (NVC) – the link between neuronal activity and cerebral blood flow. In preclinical animal models, impaired insulin signaling is associated with reduced NVC, highlighting the neurogenic role of insulin. However, it remains unclear whether brain insulin stimulation can enhance NVC in humans. PURPOSE: To examine the acute effect of intranasal insulin delivery on NVC. We hypothesized intranasal insulin would augment NVC in healthy young adults. METHODS: Carotid artery blood flow (CBF, Doppler ultrasound) and middle cerebral artery blood velocity (MCAv, transcranial Doppler ultrasound) were measured during …

Destructive Plasticity, “Surplus Of Consciousness,” And The “Monster” In True Detective, Courtney Patrick-Weber

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The first season of HBO's cult hit True Detective introduced viewers to a southern gothic murder mystery that many will not easily forget. Since many of us focused primarily on the whodunit narrative, we may have missed the narrative of trauma simmering under the surface of the story. This narrative of trauma reveals a deeper layer to the story between Detective Rust Cohle and serial killer Errol Childress, one that also reveals our own fears regarding trauma in our lives. By applying first the nihilist philosophies of Peter Zapffe with Cohle and Catherine Malabou's concept on destructive plasticity in Childress, …

The Roots Of Authoritarianism In Amc’S The Walking Dead, Adam M. Crowley

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

AMC’s The Walking Dead (2010- ) is a unique artifact in the twenty-first century’s expansive catalogue of undead-themed entertainments. To date, the show’s producers, commentators, and critics have noted the relevance of psychological trauma to the series. If the experience of realistic psychological trauma is relevant to The Walking Dead, then it should be possible for critics to articulate detailed assessments of the particular kinds of traumatic experiences that are foregrounded in the program. Trauma is, after all, an extremely nuanced and highly theorized facet of the human condition. This paper provides one such assessment and considers the significance …

“If You Want To Be The Man, You’Ve Got To Beat The Man”: Masculinity And The Rise Of Professional Wrestling In The 1990s, Marc A. Ouellette

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This paper traces the relationship between the shifting representations of masculinity in professional wrestling programs of the 1990s and the contemporaneous shifts in conceptions of masculinity, examining the ways each of these shifts impacted the other. Most important among these was a growing sense that the biggest enemy in wrestling and in day-to-day life is one’s boss. Moreover, the corporate corruption theme continues to underscore the WWE's on-screen and off-screen coverage, well into the second decade of the twenty-first century. Thus, the paper provides a template for considering a widely consumed popular cultural form in ways that challenge the determinism …

The Diyinii Of Naachid: Diné Rhetoric As Ritual, Edward L. Karshner

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Rhetoric is far more than a theory of communication or the antiquated ancestor of freshman composition courses. As a system, rhetoric is the process that directs, on the one hand, individual experiences with the world and structures, and on the other, the stories cultures tell about themselves. These foundational narratives (myths) reveal a culture’s metaphysical understanding of the nature of reality, the psychological understanding of human nature, and the epistemological notion of what can be known. Using the Diné Bahané, this paper will explore Diné rhetoric as naachid, an inclusive, outward-directed communication model of problem solving which functions …

From The Vertical To The Horizontal: Introducing Mikhail Epstein’S Transculture To Perplexed Educators, Sheldon S. Kohn

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

A shift in focus from supporting or opposing vertical, grand narratives to the horizontal, the ordinary and the everyday, can lead educators to transformative developments. Educators find themselves in a false dichotomy of being restricted to supporting or opposing competing vertical utopian visions of education. Mikhail Epstein’s ideas about transculture can help perplexed educators make a shift from the vertical to the horizontal, focusing their praxis and pedagogy on the ordinary and the everyday, including objects and artifacts of popular culture. In a radical move, Epstein argues that commodification represents resistance to totalitarian controls and impulses; he urges educators to …

“High Culture As Entertainment”: Hybrid Reading Practices In A Live Book Club, Magnus Persson

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The Bushwick Book Club (BBC) is a live book club in which invited pop musicians perform musical interpretations of a predetermined literary work in a nightclub environment. What can a typical BBC show, with its strong emphasis on popular music and performance, teach readers about the uses of literature? This case study will investigate which reading practices are at work and in what ways they challenge traditional ideas of the forms, functions, and values of reading. Another important aspect concerns how the borders between high and popular culture, and between the printed word and other media are renegotiated. Based on …
