Indiana University-Purdue University Indianapolis (IUPUI) / It is well documented that a variety of sports coaches lack nutrition knowledge. However, few studies explore their knowledge of appropriate weight loss methods, macronutrient intake, or disordered eating. Unfortunately, both college and high school coaches disseminate inaccurate nutrition and weight loss counsel to their respective athletes who are just as unknowledgeable. Further, there is little research, which only focuses on coaches of a specific sport (e.g. tennis). Thus, the primary purpose of this study was to assess high school tennis coaches' knowledge of macronutrients and disordered eating (e.g. symptoms and prevention). Other purposes included identifying confidence in knowledge and any differences between the participating coaches' knowledge and demographic variables. To address these purposes, the 27-question Nutrition and Eating Disorders in Tennis ("NET") Survey was created (and validated). The study design involved a one-time, voluntary assessment of the Indiana coaches' demographic variables, knowledge, sources of knowledge, and level of confidence (e.g. Not At All or Very Confident). Overall, the results revealed that the coaches lacked knowledge. The average score was 70.6%, which was below the criterion for adequate knowledge. Furthermore, the coaches lacked adequate knowledge in three of the five knowledge domains: Treatment and Prevention of Disordered Eating (63.6% ± 22.9%), Disordered Eating Signs and Symptoms (60.0% ± 21.7%), and Macronutrients (57.0% ± 22.4%). The latter was further substantiated through the responses to scenario questions (Part 3). Specifically, the tennis coaches demonstrated a significant knowledge deficiency of carbohydrates, energy needs, and appropriate scope of practice. There was no significant difference between coaches' education level, gender, or type and knowledge. However, there was in experience; the more years coached, the lower the scores. Moreover, there was a trend of overconfidence in the most missed questions. This dissertation's data can provide basis for coaches' educational programs.

M.A. / This study was conducted to ascertain whether there is a significant relationship between, parental pressure, stress levels and athletic performance in high school track and field athletes. The question can be asked whether parental pressure will result in increased stress levels in the athlete and therefore poorer performance? Sixty-six high school track and field athletes, between the ages of 13 and 18 years, were selected for the study. The athletes were taken from training groups and an Afrikaans high school to Provide a sample that included both elite and social athletes. The IPAT-Anxiety Scale, Sport Competition Anxiety Test (SCAT), SASOL junior tables and three self-designed questionnaires were used to determine the athletes' stress levels, amount of parental pressure and performance measurements. Significant relationships were found between parental pressure, increased stress levels and poorer performance. The more parental pressure experienced by the athlete the higher his stress levels and consequently the poorer his performance.

This study examined the effects of two distinct phases of endurance training (summer and in-season training) in previously well-trained male and female high school cross-country runners. Eleven males and 11 females from the same high school training program were recruited for the three testing sessions: post-track season (June), postsummer training (mid-August), and post-cross-country season (early-November). However, due to injury and other circumstances, only 10 males and 4 females completed all testing sessions. Thus, baseline characteristics were analyzed for both genders; however, longitudinal analysis was only conducted using the males. Submaximal measurements included running economy (RE), blood lactate concentration ([BLa]), and heart rate (HR) at three running speeds in females (6, 7, and 8 mph), and males (7, 8, and 9 mph). Maximal measurements of oxygen uptake (VO2max) and HR, neuromuscular characteristics of isokinetic knee extension strength and vertical jump height, and body composition were also measured. Baseline results showed that the males possessed a higher VO2max, greater neuromuscular characteristics, and lower submaximal [BLa] and HR values than the females. Longitudinal analysis of the males showed that there was an increased VO2max, decreased maximal HR, and decreased neuromuscular strength following summer training. In-season training precipitated further increases in VO2max, an increase in maximal and submaximal HR, and increased neuromuscular characteristics. RE and [BLa] did not significantly change (p<_ 0.05) throughout the course of the study. Likely, it is the subtle changes in these variables in previously welltrained runners which account for the slower performance times at the beginning of the cross-country season and the improvements thereafter. / School of Physical Education

Tackle football has been one of the most popular sports for boys in the United States since the mid-twentieth century. This dissertation examines how debates over the safety of football for children at the high school level and younger have changed from 1945 through the present. After World War II, the expansion of youth tackle football leagues, particularly for pre-pubescent children, fostered a new range of medical and educational concerns. Yet calls for limits on tackle football were largely obscured by the political and social culture of the Cold War, including beliefs about violence, masculinity, and competition. A broad range of groups and individuals were involved in debating the safety of youth football throughout the remainder of the twentieth and early twenty-first century. These groups included doctors, coaches, educators, lawyers, engineers, parents, athletes, journalists, and sporting goods manufacturers. Their arguments over the risks and benefits of youth football involved not only the sport’s effects on physical health, but also on social and emotional well-being. By the 1970s, researchers were applying injury epidemiology methods to studying key mechanisms involved in football injuries, while a broader consumer product safety movement contributed to the development of the first football helmet standards. Football equipment not only remained a primary focus of football safety debates, but often symbolized safety itself. Sporting goods manufacturers largely succeeded in framing the issue of football safety as a matter of individual responsibility. The social position of children and their communities shaped debates over the risks and benefits of football, including the sport’s spectator nature. By the early twentieth-first century, concerns about football-related brain injuries at all levels of the sport emerged as a topic of national debate. New medical findings and the reporting and advocacy of journalists and former athletes contributed to increasing awareness of brain trauma in the sport. Debates over the appropriate policy recommendations to make in the context of uncertainty over youth football’s long-term consequences have persisted since 1945 through the present.

Efficacy, cohesion, and sport performance have been shown to vary longitudinally (Carron et al., 2002; Shea & Howell, 2000). Tripartite efficacy is a specific area concerning efficacy beliefs within dyads that has recently grown in popularity (Jackson et al., 2013); yet no longitudinal research of intra-dyad beliefs exists. This case study examined longitudinal variations of tripartite efficacy beliefs, cohesion, and individual performances of six basketball players on a high school team over seven data collection points during a competitive season. The results indicated similar variations between participants' tripartite efficacy components and individual performance, and different variations between self-efficacy and cohesion beliefs. / Access to thesis permanently restricted to Ball State community only. / School of Physical Education, Sport, and Exercise Science

This study was designed to explore the effects of high school sport participation on female adolescent body image and self-esteem. This study also explored differences in body image and self-esteem among upperclassmen and underclassmen. The sample consisted of two adolescent female groups: 47 athletes (20 upperclassmen and 27 underclassmen) and 34 nonathletes (18 upperclassmen and 16 underclassmen). All participants took the Body Image Avoidance Questionnaire (BIAQ), Rosenberg’s Self-Esteem Scale (SES), and a Demographic Questionnaire. All data were analyzed by conducting t-tests. Results indicated nonathletes had significantly higher scores on body image avoidance than athletes, and underclassmen had significantly higher scores on body image avoidance than upperclassmen. There were no significant differences found on the self-esteem measure. Implications for research and practice are discussed. / Department of Counseling Psychology and Guidance Services
