Association Between Visuomotor Skills And The Effects Of Stroboscopic Vision On Depth Jump Performance, Riley Welch

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The reactive strength index (RSI) is a popularized method of evaluating depth jump performance. Performance in anticipation of ground impact is influenced by the proprioceptive, vestibular, and visuomotor systems through multisensory integration. The contribution of vision to depth jump performance has been studied through use of stroboscopic goggles, but no study has evaluated which visuomotor skills may be a predictor for DJ performance. The purpose of this investigation was to evaluate the association between visuomotor skills and the effects of stroboscopic vision on DJ performance. Participants consisted of 9 female and 13 male college aged adults. DJ performance was evaluated …

Comparative Effects Of Eccentric Overload Training On Muscle Function Measures When Combined With Aquatic Plyometric Training, Cassidy Weeks

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Although there is a growing body of knowledge on eccentric resistance training and aquatic plyometric training on muscle function measures alone, no research to date has investigated the effects of a mixed training model. Aquatic plyometrics and overload eccentric training are two different training models which could work synergistically because the shortcomings of one model are the virtues of the other (i.e., plyometrics are not as effective at producing large muscle size and strength gains and eccentric-only training largely lacks the functional SSC component). The purpose of this study was to examine and compare the effects of a combined eccentric …

No Evidence Of Stochastic Resonance In Postural Sway Response To Noisy Galvanic Vestibular Stimulation In Healthy Young Adults, Dominique Rice

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The transcutaneous application of a sub-sensory electrical stimulation to the vestibular afferents, known as noisy galvanic vestibular stimulation (nGVS), is thought to cause a reduction in postural sway at optimal amplitude intensities due to a mechanism known as stochastic resonance (SR). SR is a phenomenon whereby the addition of low amplitude noise to a non-linear system can be beneficial rather than detrimental. In humans, behavioral markers of SR in postural sway have been inconsistent, potentially due to insufficient power or false positives. Therefore, the main purpose of this study was to determine whether the frequency of observing SR-like effects improves …

Mindfulness-Based Practices For The Impaired Performance Athlete, Mackenzie L. Campbell

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Mindfulness-based programs are becoming commonly considered for the improvement of athlete's mental and physical state. However, their usage in improving performance in impaired athletes is limited and not fully understood. The purpose of this thesis was to review the standing literature on the topic of the application of mindfulness to improving athletic performance in wellbeing-impaired athletes. Seventy-three articles were included as references for this paper describing functional mechanisms, clinical significance and anecdotal evidence that points to the effectiveness of mindfulness in sport for the treatment of pain, injury recovery, prevention of injury, and chronic illness. Ultimately, this review supports the …

Comparison Of Land And Aquatic Loaded Countermovement Jump Landings In Female Ncaa Division I Collegiate Athletes, Samantha L. Nielson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this study was to investigate alterations in lower extremity kinematics during the landing phase of a countermovement jump when performed in different environments and under multiple external loads. Twenty-four NCAA Divison I collegiate female athletes performed 12 countermovement jumps on land and 12 jumps in water, submerged to the xiphoid process, for a total of 24 jumps. Within each environmental condition, four loading conditions of three jumps each were performed using a weighted vest: Unloaded, 10%, 20%, or 30% of body mass. The hip, knee, and ankle angles were measured as the smallest angles between the major …

Effect Of Aquatic Immersion On Static Balance, Talin J. Louder

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Objective To quantitatively assess measures of static balance and limits of stability (LOS) in an aquatic environment compared to on land. Methods Fifteen healthy, young adults (23 + or - 2 years) performed 90 s static balance trials on land and aquatic immersion at two different depths (greater trochanter, xiphoid process). Measures of 95% ellipse area and center of pressure (CoP) mean velocity were computed from the force data. Additionally, participants completed a visual analog scale (VAS) of perceived stability for each environmental condition. Following the static balance trials, participants performed anterior-posterior and medial-lateral LOS assessments. Results Significant differences in …

Lactate Threshold: Land Versus Water Treadmill Running, Ron T. Garner

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Aquatic treadmill running has become increasingly popular for rehabilitation and training purposes due to decreased joint impact on the lower extremities, which is beneficial for special populations such as the injured, elderly, arthritic, and obese (Greene et al., 2009; Hall, Grant, Blake, Taylor, & Garbutt, 2004). Accordingly, researchers have compared key differences such as heart rate (HR), oxygen consumption (VO2), respiratory exchange ratio (RER), stride frequency, and rating of perceived exertion (RPE) between land and water running at maximal and submaximal efforts (Brubaker, Ozemek, Gonzalez, Wiley, & Collins, 2011; Rife, Myrer, Feland, Hunter, & Fellingham, 2010; Rutledge, Silvers, Browder, & …

Functional Rehabilitation Of Low Back Pain With Core Stabilization Exercises: Suggestions For Exercises And Progressions In Athletes, Joshua Johnson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Introduction: Low back pain is very common in the adult population and accounts for more time lost from work than other diagnoses. It also affects athlete's at all different levels of competition and results in missed practice and game time. Diagnosing and treating a specific pathology is often difficult because clinical evaluation and radiologic studies are often unable to find a root cause. A popular treatment approach with a high volume of anecdotal evidence is the use of core stabilization exercise in the treatment of low back pain.

Purpose: To evaluate exercise as a treatment for a low back pain …

Whole Body Vibration In Anterior Cruciate Ligament Rehabilitation, Sara Ruby Vargas

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

There has been an increasing prevalence of anterior cruciate ligament (ACL) injuries. In the literature describing ACL rehabilitation program flexibility, muscle strength, proprioception, and postural stability have been identified as reoccurring struggles that have arisen during rehabilitation. Whole Body Vibration (WBV) has been investigate as a rehabilitation tool that can be used when recovering from an ACL injury. Research has suggested that WBV can be used to increase flexibility, improve muscular strength, increase proprioception, and improve postural stability. The purpose of this review is to gather the WBV protocols used in previous research and apply them to ACL rehabilitation. An …

Utah State University Return To Play Criteria Following Anterior Cruciate Ligament Surgery, Benjamin Hamilton

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

An injury to the anterior cruciate ligament (ACL) of the knee is a very traumatic experience. Most of these injuries will be a complete rupture of that ligament, and because of the nature of the ligament, the repair process will require surgery; however, a small number of athletes have learned how to successfully stabilize the ACL-deficient knee and return to activity (Hartigan et al, 2010). For the thousands of athletes who undergo surgery to repair their ACL, this is in hopes they can return to physical competition and an active lifestyle. The ACL is also repaired in hopes of preventing …

Effect Of Whole Body Vibration On Sterotypy Of Young Children With Autism, Mandi W. Gibbons

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Objective: To determine if acute whole body vibration exposure influences stereotyped behavior of young children with autism.
