In fall 2016, participants completed a pre and post SMS-28 questionnaire and a 2km ergometer aerobic capacity test. Collegiate Female Rowing team was recruited with 13 participants (ages 18-22). 4 weeks later, 7 participants filled out the SMS-28 questionnaire, based on a Likert Scale, and performed the 2km …

Metabolic Flexibility Among Women After A Single High Fat Meal, Alyssa Olenick

Masters Theses & Specialist Projects

PURPOSE: Obese women have increased rates of metabolic diseases compared to those of healthy weight status. Additionally, African-American (AA) women have higher rates of metabolic disease compared to Caucasian (CA) women. Metabolic inflexibility is the inability to adjust substrate oxidation in response to dietary intake; potentially leading to weight gain and the development of metabolic disease. Few studies have investigated the impact of weight status and/or ethnicity on the metabolic response of women to a single high fat meal. An acute unfavorable metabolic response may contribute to the higher incidence of metabolic disease among not only obese, but also AA …

Impact Of Student Fees On Winning In The Ncaa, James T. Morton

Kinesiology and Health Science Faculty Publications

The financial picture for most intercollegiate athletic departments involves the use of student fees to help offset the costs of running the department. Students were charged more than $795 million to support sports programs at 222 Division I public schools during the 2008-09 school year (Berkowitz, Upton, McCarthy, & Gillum, 2010). With that level of investment it is prudent to ask what effect on winning these funds may have. Many presidents have cited the indirect benefits athletics brings to a campus as a justification for allocating student fees to athletics. However, while much research has been done on the subject, …

Furthermore, exercise extends mortality, enhances general quality of life, and it is a protective health factor for preventing the progression some mental health disorders. Electronic athletic training equipment easily allows monitoring of real-time physical activity, and enables tracking of progress made toward individualized performance goals. There are limitations to only using visual feedback (e.g., visual depictions of heart rate, speed, distance traveled, or calories burned etc.) to track and improve exercise and athletic performance, especially for some sports, such as boxing. This issue …

Comparison Of Clinician Assisted Versus Unassisted Pnf Stretching On Hamstring Flexibility, Isometric Force Output, And Maximum Vertical Jump Height, Joel T. Lockhart

Theses and Dissertations

Introduction: Hamstring strains are among one of the most common acute injuries that occur in soccer players. Previous research has shown that reduced hamstring flexibility is a risk factor for injury, however this is modifiable through stretching. Some stretching techniques have contributed to decreased performance on measures important to success in sport. Proprioceptive neuromuscular facilitation (PNF) is one effective stretching technique to improve hamstring flexibility, but requires a trained partner or clinician to perform properly. It is unknown if the performance of PNF stretching without a clinician’s assistance could be as effective. It is also unknown if PNF stretching affects …

The Mediating Effect Of Self-Determined Motivation In Student-Athlete Perceptions Of Coaching Behaviors And Its Effect On Grit And Mental Toughness, Lloyd Scharneck

Theses and Dissertations

The aim of this current study was to examine the relationship between coaching behaviors, grit, mental toughness, and motivation. I hypothesized that coaching behaviors would have an indirect influence on grit and mental toughness through the motivational orientations of athletes. To examine these relationships, we surveyed 219 student athletes from Midwestern universities using valid and reliable measures assessing the key constructs in this study. Results revealed significant positive relationships between autonomy-supportive coaching, grit, mental toughness and autonomous motivation. Significant negative relationships between controlling coach, grit, and mental toughness were also found. Path analysis revealed two major findings. A significant positive …

Tiered Vs. Traditional Daily Undulating Periodization For Improving Powerlifting Performance In Trained Males, Andres Vargas

USF Tampa Graduate Theses and Dissertations

Daily undulating periodization represents an increasingly popular trend in exercise science with which a traditional model has been established. Tiered daily undulating periodization pairs the DUP approach with a tiered training system which allows volume and intensity to be more evenly distributed throughout a given graining cycle. The concept of tiered daily undulating periodization is a novel form of periodization and has not been investigated. As such, a comparison of traditional and tiered daily undulating periodization has yet to be examined. Therefore, the purpose of this study was to compare the effects of traditional and tiered daily undulating periodization models …

The Effects Of Trx Suspension Training On An Asymmetrical Weight Shift During A Double-Leg Squat, Samantha J. Shruck

Theses and Dissertations

Context: It is estimated that 54% of all sport related injuries are to the lower extremity, specifically the knee and ankle. Following injury, many individuals demonstrate an asymmetrical weight shift during a double-leg squat, which may increase risk of further injury. Asymmetries are driven by a variety of factors including range of motion and neuromuscular control. The goal of rehabilitation is to identify asymmetrical movement and utilize evidence-based techniques to retrain deficient movement patterns. The double-leg squat is a reliable movement task to identify asymmetrical weight shifts. Based on the theory and purpose of suspension training (TRX), it may be …

Fibroblast Proliferation In Response To Treatment By A Novel Tgf-Beta Pathway Inhibitor, Coray Preece, Robert Hyldahl

Journal of Undergraduate Research

Fibroblasts play a key role in repairing injured tissue by secreting collagen and growth factors into the tissue. In states of disease and overuse, fibroblast activity (i.e. greater fibroblast content and collagen secreting activity) can lead to skeletal muscle fibrosis, in which myofibers are replaced by collagen, decreasing strength and muscle elasticity. It has been shown in previous studies that TGF-beta signaling directly increases fibroblast proliferation and collagen secretion. It has also been shown that inhibition of TGF-beta signaling reduces known symptoms of muscular dystrophies including decreased fibrosis and increased muscular strength. SGI-1252 is a novel small molecule that our …

Alterations In Foot Positioning During Ankle Taping And Its Effects On Range Of Motion And Jump Performance In Dancers, Eilish Anderson

Theses and Dissertations

Context: A closed basket-weave ankle tape application is commonly used by healthcare professionals in order to give support to the athlete’s ankle during activity. This closed basket-weave ankle tape is used to prevent the ankle joint from going into excessive plantarflexion and inversion. Previous research has demonstrated traditional ankle taping techniques, with the ankle in a dorsiflexed position, reduces range of motion at the ankle. Due to the extreme demands placed on the ankle during dancing, which often requires the dancer to place the ankle in a maximally plantarflexed position, it is unclear how taping in this position affects range …
