Anxiety is an intense feeling of worry or fear and can often be overwhelming, taking over someone’s everyday activities. Oftentimes, individuals who have feelings of anxiety or are in stressful situations that are anxiety inducing, they can get physical symptoms such as increased heart rate, sweating, fatigue and rapid breathing. Anxiety can also affect an individual’s quality of vision. In circumstances that are highly stressful, individual’s vision can start to diminish temporarily, affecting the peripheral vision as well as making central vision blurry. This study examines the effects of anxiety and vision quality on athletic performance among collegiate athletes. It compares the impact of being in stressful situations among athletes with and without vision disorder during athletic events. By conducting a study focusing on collegiate athletes at the University of Central Florida and comparing their anxiety levels, as well as any changes in their eyesight/perception, we can assess the association between stress and eyesight, and whether this correlation has an impact on their performance. The objective of this study is to assess a potential relationship between athletes’ performance, with and without vision-related disorders, during highly stressful situations. 31 participants, between the ages of 18-27, participated in this study. Using UCF Qualtrics and incorporating the State-Trait Anxiety Survey into an online modality, the survey was sent out to all student athletes. By comparing the data collected in SSPS and One-Way ANOVA, there was no significant difference in the mean anxiety scores between the tested variables, including the type of sport played, the type of refractive errors, and wearing corrective lenses. Future research can focus on assessing a larger athlete sample and perhaps assessing anxiety and vision during performance and competition to better understand the true relationship between anxiety and vision disorders among athletes.

<p> This study was designed to investigate possible changes in insulin sensitivity (IS) with cessation of training. Six endurance trained athletes were studied at 12, 60 h and 7 days following cessation of training. In-vivo IS was established by a glucose clamp technique (Greenfield et al. Diabetes 30, 1981) and expressed as the metabolic clearance rate of glucose (MCR) in ml. plasma cleared kg-1. min-1. At 12 h after the last training session the mean MCR was 15.6+1.8 compared with 7.8+1.2(p<0.01) in age and weight matched sedentary controls. The MCR decreased to 10.1+1.0 after 60 h and decreased significantly to 8.5+0.5(p<0.05) after 7 days of detraining. In-vitro IS was measured by determining the insulin binding of fractionated young erythrocytes by the method of Polychronakos et al. (Clin. Inves. Med.4,14B,1981). Insulin binding was 10.4+0.9% at 12 h and decreased significantly to 8.1+0.7%/4xl0^9 cells after 60 h of detraining (p<0.001). In conclusion: 1) detraining of endurance athletes resulted in a rapid decrease in IS. After 7 days, glucose MCR reached values indistinguishable from sedentary controls. 2) changes in IS observed may be partially mediated by alterations in insulin binding to receptors. 3) since the high IS observed with endurance athletes on the initial test disappeared shortly after cessation of training, it is probably an acute effect of the last exercise bout rather than a chronic effect of training.</p> / Thesis / Master of Science (MSc)

The first research question sought to determine the fidelity of Team Support to Hellison's Personal and Social Responsibility model, the model it purported to implement. The second research question assessed if Team Support was perceived to be an appropriate intervention for teaching personal and social responsibility to the student-athlete participants. For the first research question, a protocol adherence rating scale was created to gather quantitative and qualitative data on approximately 110 student-athletes and 19 advisors. For the second research question, qualitative data were gathered through 2 focus groups of 8 student-athletes each, 12 individual interviews with student-athletes, 9 individual interviews with advisors, and participant observer notes to explore student-athletes and advisors' perceived social, emotional, and academic outcomes of student-athletes' participation in Team Support. The study employed descriptive statistics and thematic analyses to answer its research questions. The results of the investigation yielded short term and long term implications to urban youth, sport practitioners, school counselors, users of Hellison's model, school administrators, and other educators. / 2031-01-02
