Transcutaneous Electrical Stimulation Does Not Decrease Torque Loss Over High Intensity Repetitions, Ian Koskinen

All NMU Master's Theses

Transcutaneous Electrical Stimulation, TENS, has been used widely as an analgesic and ergogenic aid for many years. Compared to other modalities of electrical stimulation, TENS has been shown to provide some benefits in exercise performance by reducing pain and increasing endurance in low intensity applications, such as time trial cycling or isometric endurance. While TENS has been shown to have a significant effect on exercise induced pain in individuals performing endurance activities, to my knowledge it has not been examined in high intensity contractions. 18 active young adults (age: 23.11 years ± 2.08, resistance training experience: 7.08 years ± 3.79, …

Musculoskeletal Injury Concealment In The Reserve Officers’ Training Corps, Joshua D. Wooldridge

UNLV Theses, Dissertations, Professional Papers, and Capstones

INTRODUCTION: Among service members, musculoskeletal injuries threaten military readiness and place a substantial burden on medical and financial resources. While musculoskeletal injuries (MSKIs) are a leading threat to military readiness, service members’ unwillingness to seek care constrains current prevention and surveillance efforts. A growing body of evidence shows US service members conceal a large proportion of injuries, especially in training environments. The Reserve Officers’ Training Corps is a critical training environment for future US military commissioned officers. Reserve Officers’ Training Corps (ROTC) is the largest commissioning source of new officers for the US military. ROTC cadets are college students concurrently …

The Effect Of Running On The Onset And Development Of Osteoarthritis, Jordan Hekman

Senior Honors Theses

Osteoarthritis is a prominent and debilitating form of joint disease characterized by pain and deterioration of the articular cartilage and other tissues in the affected joint. Research has identified a variety of risk factors for osteoarthritis, including age, obesity, gender, previous injury, and occupation. The relationship between running and osteoarthritis is a topic of particular interest because of the prevalence of running as a simple and physiologically beneficial form of exercise. Increasing evidence suggests that recreational running has at worst no effect and at best a protective effect on joint and articular cartilage health in contrast to high-intensity professional/elite-level running …

The Relationship Between Upper Body Muscular Power And Objectively Measured Physical Function In Healthy Older Adults, Jordan Stroope

Graduate Theses and Dissertations

The population of older adults is growing rapidly worldwide. There are significant challenges associated with an aging population, many of which are related to declining physical function. Muscular power has previously been postulated as an important physical characteristic for preserving physical function, however, much of the research has measured lower body muscular power against functional outcomes. The importance of upper body muscular power (UBMP) for physical function outcomes is less clear, thus, this study sought to examine that relationship. Forty-two older adults between the ages of 50 – 70 (avg = 60.5 years  5.7) were recruited for the current …

The purpose of this study was to determine how active college students respond to flossing applied to both a joint as well as soft tissue in the lower extremities, focusing on the ankle joint and calf muscle. Floss bands were applied bilaterally for each of …

Salivary Microrna As A Concussion Biomarker And The Implications For Athletic Trainers' Practices, Thomas Richard Campbell

Rehabilitation Sciences Theses & Dissertations

Many concussions are sustained globally each year; however, research suggests that a large number may go undiagnosed due to a reliance on subjective information from patients and limitations of current objective measures. Recently, efforts have been focused on identifying clinical biomarkers of concussions, including salivary microRNA (miRNA), to improve healthcare professionals’ concussion management practices. Even if salivary miRNA were shown to be a valid and reliable measure for managing concussions, healthcare professionals, such as athletic trainers (ATs), must be familiar with the tool and have positive attitudes toward the implementation into clinical practice. Therefore, the purpose of this dissertation was …

Meeting, Moving, Mastering - A Text Analysis Of The Aesthetic Attractions Of 'Wild Swimming', Dagmar Dahl, Åsa I. Bäckström

International Journal of Aquatic Research and Education

Why are people fascinated by swimming in nature? This article addresses the aesthetic experiences of wild swimming as expressed by five wild swimming authors in their books. Drawing from aesthetic philosophy, we analyze the ways in which the appeal of wild swimming is described on three levels: the allure of water in the environment, the sensory encounter between water and the body, and the experience of moving in water. Furthermore, with reference to Seel’s concept of nature aesthetics (1996), the experience of wild swimming is analyzed in terms of contemplation, correspondence, and imagination. We can conclude that the special intensity …

Which Stroke Next? All Strokes Next! Part Two: Strokes For Intermediate And Advanced Swimmers, Robert Keig Stallman, Ebbe L. Horneman, Nils O. Vikander, Alexander Mwaipasi, Bente W. H. Laakso, Haakon - Paavo L. Nysted, Toni Ongala

International Journal of Aquatic Research and Education

The primary goal of this two-part project is to answer the rhetorical question of which strokes should be taught first, and which later (Langendorfer, 2013, Stallman, 2014a). As you have seen in Part One, we emphasize (as have many others) the need for a firm foundation before any stroke is introduced. When the learner is ready for propulsive motor competencies, there is no stroke which suits all as their first. In Part One we explored the “beginning strokes” all of which are candidates for any given learner’s first stroke. We also argued that after mastering their very first stroke the …

Towards A Globalised Vision Of Aquatic Competence, Rita F. Pinto, Juan Antonio Moreno Murcia

International Journal of Aquatic Research and Education

Human interaction with the aquatic environment has always taken different forms to meet the needs of pleasure, survival, therapy or performance. The diversity of existing aquatic spaces presents itself as a challenge, due to their variety, dynamism, unpredictability and unrepeatable conditions. These factors potentiate an infinite number of possibilities for human response in interaction with the aquatic environment, with aquatic competence being the one that will be able to sustain all types of interaction. Thus, the aim of the proposal has been to present a new approach to the contextualisation of aquatic competence. After a literature review on the concept …

Revisiting The Metaphorical Concept Of “No Strokes First - All Strokes First”: Part One - Beginning Strokes, Robert Keig Stallman Ph.D., Alex Mwaipasi, Ebbe Laakso Horneman, Nils Olof Vikander, Bente Wäinösdatter Horneman Laakso, Haakon-Paavo Laakso Nysted, Toni Ongala

International Journal of Aquatic Research and Education

The aim of this article is to address the familiar question “Which swimming stroke should be taught first?” The discussion is usually focused on breaststroke versus crawl. Provoked by these naïve discussions of which stroke should be taught first (as if stroking equals swimming, which it emphatically does NOT), the question was answered metaphorically in an earlier article “No Stroke First – All Strokes First” (Stallman, 2008a). Here in Part I we identify and describe six strokes, all of which might be a candidate for any learners ‘very first’ stroke. We describe them as beginning strokes. Having identified and learned …

The purpose of this study was to see if overtraining or burnout occurred in D1 female soccer players and the possible factors/trends that might contribute. A self-report survey was completed weekly by the 34 D1 female soccer players, which assessed sleep quality (SPQI), quality of life (QOL), academic load, soccer evaluation (ABQ), and mood states (POMS). Bi-weekly heart rate variability (HRV) was assessed for 3 minutes at rest, and a …

Effects Of Time-Restricted Exercise On Hypertrophy, Aerobic Adaptations, And Body Weight In Mice, Greco Neblina, Elias M. Malek, Michael B. Dial, Austin Cooper

Undergraduate Research Symposium Posters

Sleep and circadian rhythms are shown to impact cellular and whole-body metabolism and exercise capacity. Mice experience adaptations (e.g., hypertrophy, increased time to exhaustion) as a result of voluntary aerobic exercise. Adaptations to aerobic exercise are influenced by the time of day at which exercise is performed due to alterations in transcriptional and translational processes that affect mitochondrial abundance. It is critical to examine the gross effects of exercise timing on metabolic adaptations and other adaptations to aerobic exercise. This knowledge can help athletes and coaches organize time-optimized training schedules and help clinicians improve patient outcomes through time-of-day related adaptations …
