A Cause To Action: Learning To Develop A Culturally Responsive/Relevant Approach To 21st Century Water Safety Messaging Through Collaborative Partnerships, Angela K. Beale-Tawfeeq, Austin Anderson, William D. Ramos

International Journal of Aquatic Research and Education

Globally, and in the United States, drowning is considered a “neglected public health threat” (WHO, 2014b). Reports have shown that there are groups of people in certain communities who are at greater risk. African Americans, as a group, have a drowning death rate 9% higher than that of the overall population, with the greatest disparity being among African American youth (Gilchrist & Parker, 2014). While many national programs and organizations present water safety awareness and drowning prevention efforts within communities, very few offer multi-sectorial collaborative efforts (WHO, 2017a) among culturally and linguistically diverse (CLD) aquatic stakeholders designed to empower, promote, …

Developing And Implementing A Community-Level Para-Swimming Program, Mariett Teixeira Matias, Milena M. Parent

International Journal of Aquatic Research and Education

The purpose of this study was to examine the basic conditions required to implement a para-swimming program at the community level. This was undertaken using a qualitative benchmarking approach based on documents/literature and semi-structured interviews with representatives from 13 countries as well as from the International Paralympic Committee’s Agitos Foundation. Results indicate that successful community-level para-swimming programs should focus on promoting the inclusion of para-swimmers in swimming clubs, with integration being a step towards inclusion. The basic conditions needed to do so include facilities and logistics, financial, and human resource needs. Findings also highlight the importance of the local context …

Reestablishing A Culture Of Water Competency At An Hbcu, Knolan C. Rawlins

International Journal of Aquatic Research and Education

African American children ages 5 – 19 years drown in swimming pools at rates of 5.5 times higher than those of whites (Gilchrist & Parker, 2014). Literature suggested culture is the culprit for this disparity. A fear of water dates to slavery (Pitts, 2007). After slavery was abolished, the memory of drowning remained part of the African American culture. In the twentieth century, the popularity of swimming grew with the increase in public pools. The era of the Jim Crow laws kept African Americans out of public pools (Pitts, 2007). Although the political landscape has shifted since the Jim Crow …

Force-Time Differences Between Ballistic And Non-Ballistic Half-Squats, Timothy J. Suchomel, Christopher B. Taber, Christopher J. Sole, Michael H. Stone

ETSU Faculty Works

The purpose of this study was to examine the force-time differences between concentric-only half-squats (COHS) performed with ballistic (BAL) or non-ballistic (NBAL) intent across a range of loads. Eighteen resistance-trained men performed either BAL or NBAL COHS at 30%, 50%, 70%, and 90% of their one repetition maximum (1RM) COHS. Relative peak force (PF) and relative impulse from 0–50 ms (Imp50), 0–90 ms (Imp90), 0–200 ms (Imp200), and 0–250 ms (Imp250) were compared using a series of 2 × 4 (intent × load) repeated measures ANOVAs with Bonferroni post hoc tests. Cohen’s d effect sizes were calculated to provide measures …

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 …

Relationship Of The Srss Questionnaire With Physiological And Performance Measures, Alec Perkins

Electronic Theses and Dissertations

The overall purpose of this thesis was to validate the SRSS questionnaire. This was accomplished by conducting a single investigation using eleven well-trained weightlifters with at least one year of competition experience. These weightlifters completed five testing sessions over the course of five microcycles leading up to a competition. Every testing session took place on Monday morning prior to regular training and included: hydration testing, SRSS questionnaire, blood draws followed by a standardized warm-up protocol and squat jumps (SJ) with 0kg and 20kg. While the majority of SRSS recovery and stress items did not change with changes in VL or …

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 …

Cluster Set Loading In The Back Squat: Kinetic And Kinematic Implications, Alexander Wetmore

Electronic Theses and Dissertations

The purpose of this study was to investigate the kinetic and kinematic implications of cluster loading as a resistance training programming tactic. Cluster loading involves introducing rest during a set which may allow athletes to train at higher absolute intensities. Eleven trained males were recruited for this study. Subjects completed two testing sessions consisting of three sets of five back squats at 80% of their one repetition maximum. Cluster loading included 30s of inter-repetition rest. All testing was done on dualforce plates with four linear position transducers. Paired sample t-tests were used to determine differences between conditions with Cohen’s d …

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?, Ross Winter, Jamie Burnell

The International Student Science Fair 2018

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 …
