The Relationship Between Sport Specialization And Coping Mechanisms In Adolescent Athletes, Sara Kusner, Laura Harris

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

OBJECTIVE
(1) To describe the coping mechanisms of adolescent athletes as emotion-focused, problem-focused, or avoidant-focused coping before and after injury or illness, and (2) to compare the perceived adolescent coping mechanisms across sport specialization levels (i.e., low, moderate, or high).

MAIN OUTCOME MEASUREMENT
Demographic information was reported for the entire sample. A one-way ANOVA was conducted for each dependent variable (i.e., coping strategy) by sport specialization. For the secondary analysis the independent variable time and the dependent variable coping mechanism (i.e., task, emotion, and avoidance) were analyzed by paired t-tests. Hedge’s g effect size was calculated for any significant comparisons …

Establishing Safe Thresholds To Improve Exercise Capacity In Collegiate Athletes With Inflammatory Bowel Disease (Ibd): A Critically Appraised Topic, Emily C. Roberts, Jenny Toonstra, Andrea Cripps

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

CLINICAL SCENARIO
Crohn’s Disease (CD), Ulcerative Colitis (UC), and Indeterminate Colitis (IC) are forms of Inflammatory Bowel Disease (IBD), a complex auto-immune disorder of the GI tract. IBD can present several challenges to athletic participation due to unpredictable disease activity and uncontrollable systemic symptoms that severely impact daily activities and limit exercise/sports participation. Limited studies and a lack of standard guidelines for physical activity (PA) and exercise are additional barriers for patients. The limitation of studies and absence of standard guidelines are a particular concern for Athletic Trainers who may encounter collegiate athletes with IBD and must navigate the return-to-play …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Adopting an external focus of attention has been shown to benefit motor performance and learning. However, the potential of optimizing attentional focus for improving prosthetic motor skills in lower limb prosthesis (LLP) users has not been examined. In this study, we investigated the frequency and direction of attentional focus embedded in the verbal instructions in a clinical prosthetic training setting.

Methods: Twenty-one adult LLP users (8 female, 13 male; 85% at K3 level; mean age=50.5) were recruited from prosthetic clinics in the Southern Nevada region. Verbal interactions between LLP users and their prosthetists (mean experience=10 years, range=4-21 years) during …

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 …

Visuomotor Rotation Adaptation And Workspace Manipulation: A Behavioral And Cognitive Emphasis, Reuben N. Addison

LSU Doctoral Dissertations

This is a three-study dissertation in which we aimed to broaden our knowledge of the mechanisms contributing to a 45° clockwise visuomotor adaptation by including variations in workspace. We provide behavioral and in one study physiological outcomes as evidence to support our conclusions. In the first experiment, we observed the adaptation of movement parameters such as pathlength, movement time, resultant velocity, and normalized jerk across groups trained with rotated visual feedback with both the left and right hands. Workspace location and hand differentially affected movement trajectory length. The group that practiced the task with their nondominant, left hand showed larger …

Age-Related Changes In Corticospinal Drive During Locomotor Adaptation, Sumire D. Sato

Doctoral Dissertations

During activities of daily living, locomotor patterns must be continuously adapted according to changes in our body (e.g., bodily injuries, fatigue) and to the changing environment (e.g., walking surface). Plasticity of spinal networks and supraspinal centers, including the cerebellum and cerebral cortex, have been shown to play important roles in human locomotor adaptation. However, the neural control of locomotion and the ability to adapt locomotor patterns are altered in older adults, which may limit activities of daily living and increase fall-related injuries in the elderly population. My dissertation project is focused on understanding the role of corticospinal drive during split-belt …

Ankle Foot Orthoses Improves Ground Reaction Forces In Patients With Peripheral Artery Disease, Zahra Salamifar, Farah Fallahtafti, Iraklis Pipinos, Jason Johanning, Hafizur Rahman, Mahdi Hassan, Sara Myers

UNO Student Research and Creative Activity Fair

Peripheral artery disease (PAD) is caused by atherosclerotic blockage of the arteries in the legs. Globally, over 236 million people suffer from PAD. Intermittent claudication is the most common PAD symptom that includes muscle pain, cramping, and/or aching induced by physical activities and relieved with rest. PAD impacts gait patterns: specifically, rapid ankle plantar flexion after heel contact, which decreases optimal energy transfer. An ankle-foot orthosis (AFO) is an assistive device that improves gait in patients with neurological conditions. AFOs could help patients with PAD to improve walking kinetics. The purpose of this study was to determine the impact of …

Velocity-Based Training: Current Concepts And Future Directions, Toby Brooks, Wil Fleming, Larry Munger, Katie Munger

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology 3(1): Article 1, 2022. Velocity-based training (VBT) is a current approach to resistance training that relies on measured bar, implement, and/or athlete speed to formulate and adjust training for both long-term programming and daily training sessions. Relying on a number of available tools of varying levels of accuracy, VBT can help the strength and conditioning specialist and/or the rehabilitation professional to not only better predict strength and power over time, but also to adjust training loads in order to maximize training response in a given session. While the appeal and price points of available …

Differential Behaviour Of Distinct Motoneuron Pools That Innervate The Triceps Surae, Josh W. Cohen, Taian M. Vieira, Tanya D. Ivanova, Jayne Garland

Kinesiology Publications

It has been shown that when humans lean in various directions, the central nervous system (CNS) recruits different motoneuron pools for task completion; common units that are active during different leaning directions, and unique units that are active in only one leaning direction. We used high-density surface electromyography (HD-sEMG) to examine if motor unit (MU) firing behaviour was dependent on leaning direction, muscle (medial and lateral gastrocnemius; soleus), limits of stability, or whether a MU is considered common or unique. Fourteen healthy participants stood on a force platform and maintained their center of pressure in five different leaning directions. HD-sEMG …

Characterizing Locomotor Disturbance Perception In Young Adults, Daniel James Liss

Graduate Theses, Dissertations, and Problem Reports

Falls during walking are a leading cause of injuries across aging. Many of these falls are due to slips and trips. The ability to perceive disturbances to ongoing motion may play an important role in the control of walking balance. However, disturbance perception has been investigated in standing balance, but its role in walking balance due to slip- and trip-like disturbances remains largely unknown. Characterizing locomotor disturbance perception in young adults may lead to a more comprehensive understanding of sensorimotor walking balance control.

This work defined locomotor disturbance perception in response to slip and trip-like disturbances in young adults. We …

Exploration Of Warm-Up Protocols On Muscular Fatigue, Sahil Kapadia

Honors Undergraduate Theses

Muscular dystrophy is a genetically linked myopathy with no cure available. The lack of a cure makes early detection and treatment of muscular dystrophy imperative. When reviewing protocols examining muscular fatigue at submaximal isometric contractions, proper warm-up appeared to be absent and could have caused skewed results and conclusions. This study examines the effects of implementing a warm-up protocol before fatiguing trials. In this study, 10 adult subjects conducted fatiguing protocols with the right rectus at submaximal isometric contractions. The warm-up period included a light walk along with contractions at 20% and 33% of maximal voluntary isometric contraction (MVIC) levels. …

The Development Of A Novel Throwing Assessment For Children With Cerebral Palsy, Cory Cribb

Electronic Theses and Dissertations

Introduction: Cerebral palsy is one of childhood's most common developmental disabilities. Cerebral palsy leads to dysfunction in the upper extremities due to symptoms such as low muscle power, spasticity, and increased tone. A modified throwing assessment was constructed to examine throwing performance as a measure of upper extremity function. Purpose: To determine if the modified throwing assessment is a reliable measure of throwing performance and if the modified throwing assessment is a valid measure of upper extremity power in children with CP. Methods: The study employed a test-retest design aimed at determining the reliability of a modified throwing assessment. Seven …

Young Adult And Adolescent Balance Control Strategies During A Dual-Task Stone-Stepping Paradigm, Emily Ford

Theses and Dissertations (Comprehensive)

Stone-stepping demands greater attention and visuomotor integration, as it requires precise foot placement. The amount of attention required during locomotion is typically assessed with a secondary task, by analyzing the dual-task cost. Adolescents are suggested to have a greater dual-task cost than young adults and demonstrate balance control impairments while dual-tasking walking. The purpose of the current study was to explore the balance control differences between adolescents and young adults during a stone-stepping paradigm. We hypothesized that adolescents would experience greater balance control deficits while performing the secondary task compared to the young adults, especially while on the uneven terrain. …

An Examination Of Hip Muscle Activation In Those With Hip-Related Groin Pain During Single-Legged And Double-Legged Squats, Millissia A. Murro

Graduate Theses, Dissertations, and Problem Reports

Approximately 60% of young adults who present with chronic hip pain suffer from hip-related groin pain (HRGP). HRGP causes individuals to experience pain, dysfunction, and have a lower quality of life when compared to healthy individuals. The most severe symptoms in these individuals occur during activities that cause the hip to go through a large range of motion, such as a squat. Hip muscle activation during this task may be altered in these individuals, yet we know little about its role in the disease process and pain level in those with HRGP. Current treatment for these individuals includes surgical and …

Beginnings, Elizabeth Becker

Dance (MFA) Theses

Researcher Elizabeth Becker uses personal experiences of pregnancy alongside scholarly research on the developmental movement patterns of the human embryo, fetus, and newborn’s first year of life to explore the multiplicity of these movement patterns within and outside the womb. Becker explores the relationship between the fertilization, germinal, embryonic, and fetal stages in relation to a newborn and its mother. These movement patterns within the beginning stages of life are valuable to research because they simulate neurodevelopmental patterns, which help wire the central nervous system in early childhood. These movements also help lay the foundation for sensory-motor development and life-long …
