Attentional Focus Effects On Motor Variability, Charlend Kenneth Howard

LSU Doctoral Dissertations

Subtle changes in task instructions with associated changes of one’s focus of attention (FOA) can have measurable effects on performance and learning of complex motor skills (Wulf, 2013). The beneficial effects of adopting an external focus of attention (EF) have been well-documented in physical environments, and recently have also been demonstrated in virtual reality (VR) environments (Cochran, Aiken, Rhea, & Raisbeck, 2021; Yamada, Kuznetsov, Diekfuss, & Raisbeck, 2021). However, these studies primarily focused on performance outcomes (such as error and accuracy), with relatively less emphasis on movement coordination. Given that most human movements are motor abundant (more degrees of freedom …

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 …

Mindfulness And Physical Activity As Moderators Of Behavioral Inhibition Sensitivity And Psychological Distress, Edward Silber

LSU Master's Theses

Framed in Reinforcement Sensitivity Theory, the current study examined the moderating effects of mindfulness and moderate-to-vigorous physical activity (MVPA) on the relationship between behavioral inhibition system (BIS) sensitivity and psychological distress. Participants (N=183) were college students at a large public university in the Southeastern United States. Data were collected using an online survey with self-report questionnaires that demonstrated acceptable reliability. Data analysis utilized multiple linear regression models to test study hypotheses. Findings revealed a significant positive relationship between BIS sensitivity and psychological distress, with mindfulness and MVPA significantly moderating this association. Specifically, increased reports of mindfulness and MVPA …

Neuromuscular Control Strategy During Object Transport While Walking: Adaptive Integration Of Upper And Lower Limb Movements, Ahyoung Song

LSU Doctoral Dissertations

When carrying an object while walking, a significant challenge for the central nervous system (CNS) is to preserve the object’s stability against the inter-segmental interaction torques and ground reaction forces. Studies documented several strategies used by the CNS: modulation of grip force (GF), alterations in upper limb kinematics, and gait adaptations. However, the question of how the CNS organizes the multi-segmental joint and muscle coordination patterns to deal with gait-induced perturbations remains poorly understood. This dissertation aimed to explore the neuromuscular control strategy utilized by the CNS to transport an object during walking successfully. Study 1 examined the inter-limb coordination …

Contribution Of Velocity Congruency And Apparent Stiffness To Interference Of Bimanual Rhythmic-Discrete Movements., Marcelline E. Dechenaud

LSU Master's Theses

Many actions feature rhythmic and discrete movements, individually or in combinations. Rhythmic movements are defined as those having no clearly defined start and end-point, while discrete movements have a definite starting and ending posture. Performing a discrete movement against a base rhythm by the contralateral limb typically speeds up the rhythmic movement -- indicating the presence of bimanual coupling. While bimanual rhythmic/rhythmic interaction has been studied extensively in the field, understanding of the interaction between discrete and rhythmic movements has been less represented. In this thesis, I examined two potential sources of interlimb interference during rhythmic-discrete bimanual actions: 1) velocity …

Neuromotor Control Of The Hand During Smartphone Manipulation, Prasanna Kumar Acharya

LSU Doctoral Dissertations

The primary focus of this dissertation was to understand the motor control strategy used by our neuromuscular system for the multi-layered motor tasks involved during smartphone manipulation. To understand this control strategy, we recorded the kinematics and multi-muscle activation pattern of the right limb during smartphone manipulation, including grasping with/out tapping, movement conditions (MCOND), and arm heights.

In the first study (chapter 2), we examined the neuromuscular control strategy of the upper limb during grasping with/out tapping executed with a smartphone by evaluating muscle-activation patterns of the upper limb during different movement conditions (MCOND). There was a change in muscle …

Eye-Hand Coordination Varies According To Changes In Cognitive-Motor Load And Eye Movements Used, Matthew Alan Yeomans

LSU Doctoral Dissertations

In this dissertation three studies were used to help improve the understanding of eye- hand coordination control of visuomotor reaching tasks with varying cognitive loads.

A brief introduction in chapter 1 is followed by a detailed literature review in chapter 2. Results from the three studies presented in chapter’s 3-5 further advance our knowledge of the integrated control used for goal-directed visually-guided reaches. In the first study (chapter 3), the additional cost associated with the use of smooth pursuit …

An Investigation Of Athletic Buoyancy In Adult Recreational And Sport Club Athletes, Jackie Rae Victoriano Calhoun

LSU Doctoral Dissertations

Athletic buoyancy is the ability of an athlete to effectively handle the daily setbacks and challenges they face during training and competition. Although buoyancy has received ample research in the academic domain, a dearth of information exists regarding buoyancy in the athletic domain. Therefore, the overall purpose of this dissertation was to investigate athletic buoyancy’s independent contribution to sport psychology while also exploring antecedents and outcomes in adult athletes.

Study 1 compared athletic buoyancy to other cognate constructs, or similar constructs, to determine their conceptual boundaries. A one-time, online questionnaire was distributed to 294 recreational athletes (M age = …

Geometric Visual Illusion Effects On Visual Perception And Visuomotor Control: Emphasis On The Vertical-Horizontal Illusion, Shijun Yan

LSU Doctoral Dissertations

The focus of this dissertation was to explore the effects of potential vertical-horizontal (V-H) illusory influences on perceptuomotor control. As part of this focus, we examined the potential use of separate cortical visual streams: the ventral visual stream for perception and the dorsal visual stream for action. Three studies were conducted to determine the effects of the V-H illusion influences on length estimations using upper limb point-to-point movements and lower limb stepping movements, involving various illusory configurations, movement directions, gaze directions. After a short introduction (Chapter 1) and a more detailed review of existing literature (Chapter 2), we present manuscripts …

Influence Of Hydration Status On Running Performance And Makers Of Psychological And Physiological Stress In High School Cross Country Runners, Joshua Granger

LSU Master's Theses

Adequate hydration is an important attribute to an individual’s health and wellbeing. This is highlighted in athletic populations, who are at great risk for hypohydration, regardless of age, sex, and sport. The rampant hypohydration observed in athletes is present at all levels of competition, from professional athletes, with access to substantial monetary and nutrition support to division 3 and recreational athletes who often face monetary challenges. This trend continues to trickle down to lower levels of competition, such as high school, where athletes often practice and compete in dehydrated states. Practicing in these hypohydrated states can cause health issues such …

Impact Of Psychological And Physical Stressors On The Exercise-Induced Immune Response In Collegiate Swimmers, Connor Alexander Kuremsky

LSU Master's Theses

Evidence suggests high-intensity exercise training increases incidence of upper respiratory infection in young-adult athletes (Spence et al. 2007). Collegiate athletes experience chronic stress, which has been shown to result in increased proportions of late-differentiated CD8+ T-cells of a dysfunctional phenotype (Bosch et al. 2009). However, many studies fail to consider possible moderators such as psychological stress and cytomegalovirus (CMV) infection. Purpose: To examine the impact of psychological stress, CMV infection, and exercise on proportions of early- and late-differentiated CD4+ and CD8+ T-cells in collegiate swimmers over a 7-month training period. Methods: Data were collected from NCAA …

Examining Anxiety And Achievement Goal Theory In Physical Activity Settings, Timothy Michael Dasinger

LSU Doctoral Dissertations

In the United States (US), a majority of adults do not meet the recommended guides of physical activity despite the many benefits. One benefit of activity is the reduction of anxiety. Although there is robust evidence demonstrating the anxiolytic effects of physical activity, the mechanism is not fully understood. Some psychological explanations are related to a lack of confidence in one’s ability. Because of this, Achievement Goal Theory (AGT) may be a viable framework to explain the anxiolytic effects of physical activity. The focus of this dissertation is to examine the efficacy of AGT as a mechanism and to explore …
