The Role Of Gut Health In Parkinson’S Disease: The Impact On Motor Symptoms And Fitness Levels, Kaylie Zapanta, E Todd Schroeder, Beth E. Fisher

International Journal of Exercise Science: Conference Proceedings

While Parkinson’s disease (PD) has traditionally been considered a central nervous system disease, recent groundbreaking research argues that PD symptomology is influenced by gut microbiota alterations (dysbiosis).¹ People with PD suffer from dysbiosis,^2-6 and gut symptoms characteristic of dysbiosis, like constipation.^7,8 Given this evidence, strategies that improve gut health in PD are warranted. One possible strategy is exercise. In non-PD populations, fitness status is linked to gut health,^9-13 and exercise which increases fitness status improves the gut.^14-19 It is now known that exercise improves motor symptoms in PD,^20-23 but the gut may be a …

The Two-Dimensional Relationship Between Ground Reaction Force Vector And Knee Axis Of Rotation Reflect Knee Loading Deficits During Squatting Post-Aclr, Jiaqi Wang, Susan Sigward

International Journal of Exercise Science: Conference Proceedings

PURPOSE

Individuals post-anterior cruciate ligament reconstruction (ACLr) perform reduced knee extensor moments (KEM) during squats by shifting weight to the non-surgical (NSx) limb ¹ or by shifting demands from the knee to hip ^1,2. These compensations occur without observable differences in joint angles by small adjustments in the center of pressure (COP). This makes them difficult to detect and may contribute to their persistence. Differences between limbs in COP position suggest that individuals adjust the relationship of the ground reaction force vector (GRFv) relative to the joint center to redistribute the loading demands in the surgical limb ³. …

Stimulated Muscle Contractions Regulate Membrane-Bound And Soluble Tlr4 To Prevent Lps-Induced Signaling And Myotube Atrophy In Skeletal Muscle Cells, Jeremy B. Ducharme, Zachary J. Fennel, Zachary J. Mckenna, Quint N. Berkemeier, Michael R. Deyhle

International Journal of Exercise Science: Conference Proceedings

Toll-like receptor 4 (TLR4) activation by lipopolysaccharides (LPS) contributes to chronic inflammation and causes upregulation of muscle atrophy signaling pathways. Exercise can suppress LPS/TLR4 axis activation by reducing the expression of TLR4 on immune cells. It is unknown how this regulation occurs, and it is not clear how exercise affects TLR4 on skeletal muscle. PURPOSE: To uncover the nature and mechanisms by which exercise affects TLR4 expression and intracellular signaling using cell culture models and human experiments. METHODS: C2C12 myotubes were subjected to electrical pulse stimulation (EPS) with and without subsequent treatment with 500 ng/mL lipopolysaccharide (LPS) along with …

Sex Differences In Hemodynamic Response To High Intensity Interval Exercise (Hiie), Leah N. Coe

International Journal of Exercise Science: Conference Proceedings

There are sex differences in the cardiorespiratory and hemodynamic response to exercise due to inherent differences in heart size, blood volume, and hemoglobin mass that elicit a higher VO₂max in men versus women. These alterations in cardiac structure and function may mediate changes in VO₂max per the Fick Equation. However, existing data are inconclusive on whether sex differences in training responsiveness exist. PURPOSE: The purpose of this study is to investigate potential sex differences in the hemodynamic response to HIIE. If men and women reveal discrepant cardiovascular responses to HIIE, this may partially mediate sex differences …

Inter-Step Height Variation Of Stairways And Observations Of Fall-Related Events, Chayston B. Brown, Shandon Poulsen, Chris Dakin, Sara Harper, Tyson Barrett

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Variation in step height within a stairway could negatively impact safe stairway negotiation by decreasing step height predictability, and consequently, increasing stair users’ fall risk. Unfortunately, inter-stairway step height variability is common, particularly in older stairways, but its impact may be lessened by highlighting steps’ edges using high-contrast stripes on the top front edge of each step. Such contrast enhancement may draw greater attention to the steps’ edges and potentially enhance the precision of the edge’s estimated location. PURPOSE: To determine (1) if fall-related events are associated with greater inter-step height variation, and (2) if such fall-related events are …

The Impact Of Squat Velocity On Force, Power, And Muscle Activity, Kyle D. Puccini, James Baldonado, Bonnie Yee, Christie R. O'Hara

International Journal of Exercise Science: Conference Proceedings

The squat is a thoroughly examined movement pattern and commonly used in sport performance training protocols, rehabilitation programs, and recreational exercise. Previous research measuring absolute strength has shown hamstring muscle activity in a six-repetition max barbell back squats. PURPOSE: The purpose of this study is to examine the effects of varying squat velocities (25, 50, 75 deg/s) on force, power, and the activation of the quadricep and hamstring muscles. Using a single-blind randomized research design, we hypothesized that hamstring muscle activity will increase at faster squat velocities. Our secondary hypothesis is that peak power will occur at 50 deg/s and …

Impact Of Mask Wearing On Post-Exercise Hemodynamics, Payton J. Price, Zachary Zeigler, Luke Heikka, Adarius West, Sofia Harman, Anthony Acevedo

International Journal of Exercise Science: Conference Proceedings

As the guidelines regarding COVID-19 regressed, many fitness centers established regulations requiring mask-wearing during exercise. Data suggest that the impact of a mask during exercise has minimal effects on exercise hemodynamics. The post-exercise period has been described as a window of opportunity to lower blood pressure, a phenomenon called post-exercise hypotension. The impact of wearing a mask on post-exercise hemodynamics is unknown. PURPOSE: The purpose of this study was to examine the impact of mask-wearing during exercise on post-exercise hemodynamics. METHODS: Nine total participants aged 18-30 yr were recruited for this experimental cross-over study. This within-subject design involved …

Muscle Mitochondrial Function At Different Phases Of The Menstrual Cycle, Brandon S. Pfeifer, Briell King, Erin Atkinson, Chad R. Hancock, Robert D. Hyldahl

International Journal of Exercise Science: Conference Proceedings

The effect of menstrual cycle (MC) phase on muscle recovery from damage has been studied using markers of strength and soreness, but remains inconclusive. Mitochondrial function is essential for muscle recovery, and has been found to be influenced by estradiol (E2). Understanding the relationship between MC phase and mitochondria can provide further insight into women’s muscle health. The PURPOSE of this study was to determine how MC phase affects markers of muscle damage and recovery, with emphasis on mitochondrial function, following electrically-stimulated muscle contractions. METHODS: 22 premenopausal females were recruited and split into two groups, early follicular (EF) and …

Diagnosis And Excision Of A Solitary Trichoepithelioma, Leonid Skorin Jr., Do, Od, Ms

Optometric Clinical Practice

Abstract

Background: Solitary trichoepithelioma is a rare benign tumor of hair follicle origin. Although trichoepithelioma has a predilection for the face and neck, it is not usually found on the eyelids. It has similar clinicopathological features to basal cell carcinoma. Surgical excision and histopathologic analysis is helpful for correct diagnosis.

Case Report: A 59-year-old Caucasian female presented with a raised, reddish oval mass on the right lower eyelid. The mass had telangiectatic blood vessels on its surface, was non-pigmented and slightly umbilicated. It was in close approximation of the eyelid margin causing distortion and poor apposition of the lid to …

Predictors Of Ncaa Division I Women’S And Men’S Cross-Country Performance, Mac John Carder Iii

Student Theses and Dissertations

Division I cross country (XC) running has many factors that influence performance and is extremely difficult to predict. Consequently, coaches often struggle to identify performance potential in athletes. In this study, personal best race times, VO2max, triceps skinfold, and a series of counter movement jump assessments were performed by female (n=15) and male (n=17) NCAA XC runners to predict XC performance. Simple regression modeling identified 3200-m high school (HS) personal best (PB) time as best predictor for men’s 8-km performance (r = 0.85; p = 0.005, SEE = ± 0.65 min). For women, a model including triceps skinfold, vertical jump, …

Association Of Functional Movement Screen And Y-Balance Test Scores With Injury In Elite Fast-Pitch Softball Athletes, Xiujing Zhao

Student Theses and Dissertations

The purpose of this study was to evaluate the association of FMS and YBT composite scores with injury in elite female fast-pitch softball athletes. Thirty-eight participants completed pre-season FMS and YBT assessments. Injury data were collected on the next day of finishing the season. FMS composite scores were significantly lower for the injured group (13.5 ± 2.4) comparison to the non-injured group 16.9 ± 1.6) (p ≤ .001, d = 1.67). Injured status was associated with lower FMS scores (r = .61; p <.001). No differences existed in YBT-UQ (p =.67, d = .14) and YBT-LQ (p =.16, d =.50) composite score between the injured (UQ = 96.0 ± 5.9, LQ = 96.7 ± 8.2) and the non-injure (UQ = 97.1 ± 1.6, LQ = 101.0 ± 9.1) groups; no significant associations were found between injury status and YBT-UQ composite scores (r = -.08; p = .64) or YBT-LQ composite scores (r = -.24; p = .14). Preseason FMS composite score was associated with subsequent injury.

This Is Sparta!: Attitudes Of Ncaa Division I Compliance Officers Towards Athlete Agent Regulations, Mark Thomas Gurenlian

Student Theses and Dissertations

The topic covered in this Thesis is that of the Sports Agent Responsibility and Trust Act (SPARTA), the state adopted Uniform Athlete Agents Act, and any other laws that are used to control athlete agents. Specifically, how these laws fail to properly protect collegiate student-athletes and fail to regulate athlete agents. There is a review of previous articles and research that promote the idea that SPARTA was not fully comprehensive and that the UAAA laws are missing key details. The study consists of a questionnaire sent to Division I compliance officers and their responses supported the notion that not only …
