Fascicle Arrangement In College-Aged Athletes, Jacob Goodin

Electronic Theses and Dissertations

Purpose: To compare muscle architecture variables between sport and sex in competitive athletes, and to compare muscle architecture with performance variables in strong versus weak athletes, and good versus poor jumpers. Methods: The vastus lateralis (VL) and lateral gastrocnemius (LG) muscles of 139 collegiate athletes were collected using ultrasonography to determine muscle thickness (MT), pennation angle (PA), fascicle length (FL), and relative fascicle length (FL_rel). Absolute and relative peak power, absolute and relative isometric peak force, and jump height were measured in a subset of baseball and soccer athletes. A 5x2 factorial analysis of variance (ANOVA) was used …

Preparing For A National Weightlifting Championship: A Case Series, Spencer K. Travis

Electronic Theses and Dissertations

The purpose of this thesis was to observe psychological, physiological, and performance changes to determine when two high-level weightlifters were peaked for a major competition. We addressed this purpose by conducting a two-part case study series with one USA international level female and one USA national level male weightlifter. Both athletes were considered to be peaked on competition day. The results support our hypothesis that jumping performance would be peaked on competition day corresponding with an increased recovery and decreased stress state. However, contrary to our hypothesis, each athlete exhibited small decreases in muscle size leading into the competition relative …

Adapted Aquatics For Children With Severe Motor Impairments, Phillip Conatser, Eric James, Ulku Karabulut

International Journal of Aquatic Research and Education

Available research clearly shows that more children who have disabilities, including those with severe disabilities, are participating in swimming programs as well as wanting to be taught in a regular aquatic class without being segregated. Aquatic instructors need to prepare lessons that include children both with and without disabilities. This means that aquatics instructors need to understand and be willing to implement unique teaching and managerial techniques that foster the safe and successful learning environment for all children. While the task of teaching children who have severe disabilities may seem difficult at first, with a little knowledge and experience, instructors …

Laterality In The Power Five And Group Of Five Conferences In Women's College Softball, Jon C. Nachtigal

Health, Exercise, and Sports Sciences ETDs

Females in sport are under-represented in data and analysis when compared to their male counterparts. This disparity also applies to women’s softball in comparison to men’s baseball. To help fill this gap, this study evaluated the extent and impact of laterality in women’s college softball’s Power Five and Group of Five conferences from 2015-2017.

This study focused on the extent of a left-sided lateral preference in women’s college softball, possible interactions between throwing hand and batting preference, to what extent the platoon effect exists in the sport, and the extent of positional bias in the sport. As one of the …

Investigating Sports Drinks. Are they worth the money?

The sports drinks industry is a huge global business which shows no signs of slowing down. The inspiration to conduct this investigation came from an observation that there is an increasing consumption of sports and energy drinks within our community, particularly amongst children. The message from the advertisers is clear- athletes should replace lost body fluid with drinks that contain electrolytes, such as sports drinks. However, there are conflicting suggestions from conducting literature reviews; that, not only are these drinks unhealthy in terms of the high sugar content, but instead water …

An Examination Of Optimism Between Gender, Race, And School Classification Of Millennial Students – An Exploratory Study, Abigail C. Johnson

Honors College Theses

Optimism is defined as an individual’s approach to the expectation that good things will happen in the future and bad things are a rarity. Along with the general definition of what optimism is, many researchers have found that optimism depends on culturally embedded values and beliefs (Singh & Shukla, 2014; Lee & Mason, 2013). In addition, the relationship between optimism and positive health outcomes and well-being is well established (Coll, J.E. & Draves, P. R., 2008; Bastianello, M. R., Pacico, J. C., & Hutz, C. S., 2014). Although this is the case, little research has been found examining the differences …

White Crane Spreads Its Wings And Snow Rabbit Digs The Earth: Kinetograms Of Contrasting Styles Within Chinese Martial And Meditative Arts Of Taijiquan (T’Ai Chi Ch’Uan, 太极拳) And Qigong (Chi Gong, 气功), Keith Mcewing

Journal of Movement Arts Literacy Archive (2013-2019)

Taijiquan is a Chinese martial art that developed in the 17th century from a base of traditional forms from earlier centuries. Now widely practiced internationally, it is promoted as gentle exercise, as self-defense and as movement meditation with significant health benefits. Qigong, consisting of similar movement but intended entirely as a health benefit, has been practiced for considerably longer. This paper discusses the advantages of having Taijiquan sequences or forms recorded with Kinetography Laban/Labanotation over other various memory aids for learning the martial art. It explains the basic principles of Taijiquan and how these can be best captured in the …

The Assessment Of Isometric, Dynamic, And Sports-Specific Upper-Body Strength In Male And Female Competitive Surfers, Joanna Parsonage, Josh Secomb, Rebecca Dowse, Brendon Ferrier, Jeremy Sheppard, Sophia Nimphius

Research outputs 2014 to 2021

The primary purpose of this study was to investigate gender differences in the dynamic strength index (DSI): an assessment of upper-body dynamic strength relative to maximal isometric strength. The secondary purpose was to investigate gender differences in the dynamic skill deficit (DSD): an assessment of sports-specific dynamic strength relative to maximal isometric strength, and its association with a sports-specific performance measure in surfers. Nine male (age = 30.3 ± 7.3 yrs) and eight female (age = 25.5 ± 5.2 yrs) surfers undertook three upper-body assessments: isometric push-up, dynamic push-up, and a force plate pop-up to determine the DSI and DSD. …

A Content Analysis Of Sports Illustrated’S Portrayal Of Female Athletes And Its Impact On Society, Britney Murray

Masters Theses

This study utilizes a content analysis of Sports Illustrated covers from 1954-2016 to evaluate the amount and type of coverage permitted to female athletes through this source of print media. The covers were critiqued for both quantity and quality as it relates to the coverage afforded to female athletes and how it differs from the coverage of male athletes. The results from this study provide a foundation for those who wish to further explore and raise awareness on the issue of underrepresentation and misrepresentation of female athletes in sports media.
