Freestyle: A Guide To Making Swimming Nutrition Simple, Megan Wills

Undergraduate Theses

Nutrition plays a critical role in the performance of an athlete. Although academic research surrounding the topic has increased, there is a disproportionate increase in materials created for the athletes themselves. Regarding competitive swimming, the scope of athlete-friendly instructional materials is even more limited. Therefore, there is an inherent disconnect between the academic research on the topic of competitive swimming nutrition and the athletes who need the information. The purpose of this project is to bridge the gap between the research and the content accessible for athletes themselves. Using an interpretive and simplistic approach, the available academic research was used …

The purpose of this research was to examine the effects that the phases of the menstrual cycle, in accordance with the surges and lulls of estrogen, have on performance outcomes.

METHODS: Twenty-six college-aged subjects who were moderately active based on ACSM guidelines and who have a menstrual cycle were included in two sessions of testing. For the first session, subjects completed the …

The Impact Of Sleep On Athletic Performance: A Review Of The Literature, Rylan J. Pratt

Honors Thesis

This paper reviewed the literature regarding sleep and athletic performance, specifically identifying the problem of sleep debt in student athletes, the effects of sleep debt, and what factors negatively influence sleep, along with how to improve sleep. The literature revealed that it is common for athletes to not get adequate sleep. Sleep debt can have psychomotor and physiological effects on the body, which decreases optimal athletic performance. The many factors that negatively impact sleep include high intensity training sessions, travel, sleep disturbances, caffeine and/or alcohol consumption, and pre-competition anxiety. Recommendations for athletes that are struggling to achieve adequate sleep include, …

Validation Of A Single Channel Eeg For The Athlete: A Machine Learning Protocol To Accurately Detect Sleep Stages, Kayla Thompson, Kamil Celoch, Frankie Pizzo, Ana I. Fins, Jaime Tartar

Journal for Sports Neuroscience

There is a large and growing movement towards the use of wearable technologies for sleep assessment. This trend is largely due to the desire for comfortable, burden free, and inexpensive technology. In tandem, given the competitive nature of professional athletes enduring high training load, sleep is often jeopardized which can result in adverse outcomes. Wearable devices hold the promise of increasing the ease of monitoring sleep in athletes which can inform health and recovery status, as well as aid performance optimization. However, wearable devices typically lack sufficient validity to assess sleep – and especially sleep stages. To address this concern, …

Assessment Of Core Stability: Developing Practical Models, Andy Waldhelm

LSU Doctoral Dissertations

Core stability is a concept in the health and fitness professions which became popular in the early 1990s. Despite its popularity, core stability remains a generalized term, which is poorly understood and lacks a universal definition and gold standard assessment. This makes it difficult to identify the role of core stability in athletic injury prevention and performance. To better assess core stability, the objective for this dissertation was to construct a reliable core stability index using measurements which best define and evaluate core stability. The purpose of our first experiment was to introduce and determine the intra-tester reliability of clinical …

Electromechanical Delay Of The Knee Extensor Muscles Is Not Altered After Harvesting The Patellar Tendon As A Graft For Acl Reconstruction: Implications For Sports Performance, Anastasios D. Georgoulis, Stavros Ristanis, Anastasios Papadonikolakis, Elias Tsepis, U. Moebius

Journal Articles

Although the scar tissue, which heals the donor site defect, has different elasticity from the neighbouring patellar tissue, it remains unclear if this scar tissue can lead to the changes of the electromechanical delay (EMD) of the knee extensor muscles. If such changes do exist, they can possibly affect both the utilization of the stored energy in the series elastic component, as well as the optimal performance of the knee joint movement. The purpose of this study was to investigate the influence of harvesting the patellar tendon during anterior cruciate ligament (ACL) reconstruction and the associated patellar tendon scar tissue …
