This thesis aimed to enhance understanding of the nature of knowledge bases possessed by elite sports performers which underpin perceptual-cognitive and decision making skills. Two main theories were considered; Active Control of Thought (ACT*) and Representational Redescription (RR). The purpose of Study 1 was to examine the anticipatory ability of elite and non-elite players in football and hockey. The results indicated that elite players in both sports were quicker and more accurate in their expectation of pass destination. Study 2 aimed to understand the extent to which knowledge is transferable. The results indicated that elite players’ knowledge is relatively domain specific although some elements of underlying task strategy may transfer. The objective of Study 3 was to explore the means by which elite and non-elite players in football and hockey identify and differentiate between possible decisions. Results showed elite players’ rationale was based on deeper theoretical principles whilst non-experts utilised relatively superficial information and naïve theories. Study 4 focussed on problem representations of elite and non-elite football players. Results revealed elite players’ representations were more pertinent, connected and articulated in a more effective manner. Overall, the findings from the current thesis provide advanced understanding of the knowledge bases responsible for perceptual-cognitive and decision making skill, and such understanding may assist attempts to enhance athletes’ performance and support future research.

Recent research suggests that psychological techniques may facilitate injured athletes' rehabilitation, yet little is known about the psychological techniques trainers currently employ and how they view these interventions. In this study, 206 athletic trainers assigned Likert scale ratings to 11 psychological techniques indicating how much they valued a specific technique, how skillfully they employed it, and how often they utilized it. Trainers also responded to an open ended question asking how they would deal with the psychological aspects of an injury described in a short scenario. Results revealed a tentative model for the way trainers view psychological techniques. Categories of techniques included techniques involving the modification of physical and psychological states (goal setting, pain management, relaxation, imagery, and breathing techniques), techniques involving verbal cognitive techniques (communicating openly, changing negative self talk, emotional counseling, and crisis counseling), and non-recommended techniques (encouraging heroism and screening negative information). The study explored trainers' perceptions of each of the 11 psychological techniques in depth and discussed these findings. The study found that although trainers highly value psychological interventions in their work with injured athletes, they assigned low ratings to the techniques they knew little about. However, as exposure to sport psychology information increased, ratings assigned to the techniques that modify physical and psychological states also increased. Similarly, the longer trainers had worked in their field, the more highly they valued the verbal cognitive interventions. In contrast, neither exposure to sport psychology information or athletic training experience proved predictive of ratings assigned to the non-recommended psychological techniques. These findings suggest the importance of introducing skills training for psychological techniques early in the athletic trainers' educational curriculum so that trainers can gain awareness of the efficacy of certain psychological techniques and skill at using these techniques. Moreover, trainers could benefit from course work explaining potential negative consequences of employing harmful or ineffectual psychological interventions.

Participation in sports has a strong influence on the development of African American youth and the Black community as a whole. The purpose of this paper is to explore the positive and negative effects that participating in sports has on the African American community using previous works and experiments on the topic. Results found that participation in athletics helps African American youth develop important social skills, creates an outlet to keep Black youth off the streets in impoverished neighborhoods, and establishes a vehicle to help Black youth get into college. However, the overemphasized importance of sports within the African American community through the media and Black families themselves has resulted in multiple negative effects including career immaturity, lower academic achievement and the exploitation of the Black intercollegiate athlete.

Home field advantage remains one of the least understood phenomenon in sports. Much effort has been put into testing the different components that contribute to the phenomenon, but a clear explanation is lacking. The purpose of the present paper is to provide a better understanding of home field advantage by analyzing previous literature and experiments on the topic. The paper will also organize the major components involved in home field advantage by updating Courneya and Carron’s conceptual framework. The paper will explain the importance of studying the topic and will highlight significant experiments that have produced contradictory results. Lastly, the paper will focus on the critical psychological states of the competitors, as it remains the least understood component of the aggregate study. Keywords: home advantage, athletic competition, Courneya and Carron

As early as 1994, and with transformation in mind, the African National Congress (ANC) identified the development of the previously disadvantaged communities in South Africa as a national priority. In so doing, sport, among others, was used in this strategy as a medium to improve and change the circumstances of people in disadvantaged communities. Sports development in disadvantaged communities is essential, if taken into consideration that without such further support of the sport talent of some of these children, the needs of these talented children cannot be met and their potential will remain undeveloped. Talent identification (TID), which is based on scientific principles and forms the first step in sports development, still is relatively new in South Africa. Historically, coaches used their own knowledge and experience of the characteristics, which should lead to success in sport as well as participation in competitions in order to do TID. To date, very little research has been done on talent identification and development in sprints and long-jump, especially pertaining to young boy and girl athletes, and in particular concerning athletes from disadvantaged communities. The first and second objectives of this study were to implement sport specific athletics development programmes aimed at improving sprinting and long-jump ability and to determine its effect on the abilities and skills of talented 10 to 15 year-old girls and boys with talent for sprints and long-jump. The third and fourth objectives of this study were to establish which kinanthropometric, physical and motor components will play such a role in 10 to 15 year-olds that it can predict performance ability in sprints and long-jump in girls and boys at this age. The "Australian Talent Search" protocol was used to identify general sport talent in the children (66 girls and 62 boys) who were identified for the study. The talented children (19 girls and 21 boys) from the initial group of were then subjected to a sport specific test battery for sprints and long-jump. The maturation level of the boys was determined by means of a maturity questionnaire, based on the 5 Tanner stages. By using the Statistica and SAS computer programmes, independent t-testing, covariance analyses, correlation coefficients, effect sizes, descriptive statistics as well as a stepwise multiple regression analysis were used to analyze the data with regard to the above-mentioned objectives. A p-value smaller than or equal to 0.05 was accepted as significant. From the results of the study it is evident that the development programmes contributed to the improvement of physical and motor abilities and skills important for performance in both sprints and long-jump in girls (n=19) and boys (n=21) respectively. Among the girls, flexibility, explosive power, muscle endurance, reaction time, speed, speed endurance, acceleration and long-jump showed statistically significant improvement, while abdominal muscle strength and stride length showed no improvement. Secondly, it was established that the development programme contributed statistically significantly to an improvement in flexibility, muscle endurance, 0-40 metres speed and long-jump ability in boys. However, some components did not show improvement, among them explosive power, reaction time, speed endurance, acceleration and stride length. A stepwise multiple regression analysis was used to analyze the third and fourth objectives. It indicated that, in respect to the 100 metres sprint, 7 variables, namely long-jump, push-ups to the point of exhaustion, 7-level abdominal strength, 0-5 metres speed, ankle dorsiflexion, body length and age contributed 84.0% to the total variance in girls. As for long-jump, 7 variables, namely 0-100 metres speed, body length, 7-level abdominal strength, push-ups, ankle dorsiflexion, standing long-jump and body mass proved to be the most important contributors to performance in these items with a total contribution of 79% to the total variance. The fourth objective indicated that average anaerobic power output, acceleration and body mass contributed statistically significantly to performance in the 100 metres sprint in boys with a contribution of 86.5% to the total variance. Horizontal jump, age and acceleration contributed statistically significantly to long-jump performance with a contribution of 81 5% to the total variance. It is evident from this study that sport specific development programmes can successfully be implemented on girls and boys at ages 10-15 in order to improve sprinting and long-jump ability, regardless of poverty-stricken circumstances and poor infrastructure. Furthermore, the study brought to light that specific kinanthropometric, physical and motor abilities exist which can be used to predict performance in sprints and long-jump in girls and boys separately at ages 10 to 15. / Thesis (Ph.D. (Human Movement Science))--North-West University, Potchefstroom Campus, 2007

The aim of this thesis is to produce a substantive grounded theory of junior-to-senior transition and as a result of this work, to provide knowledge and guidance for coaches, sport psychologists and other personnel supporting young aspirant athletes. Underpinned by a social constructionist philosophy, the research programme was designed to capture and interpret the social world of the participants and to interpret the perceptions derived from their own lived experience of the transition. The thesis consists of three studies which, in a concatenated programme of research, are predicated one upon another. In order that understanding in social research can be advanced, the development of theory requires several rounds of fieldwork, analysis and publication (Stebbins, 1992,2006). Thus the building of theory took place over the initial two studies, the first of which involved the in-depth interviewing of nine participants from individual sports (M age = 24.5 years, S. D. = 4.3 years). As a consequence of this exercise, rich data were collected, depicting the participants' experiences of the juniorsenior transition. Grounded in these data, a preliminary model of junior-to-senior transition was constructed using Strauss and Corbin's (1998) guidelines for grounded theory analysis. More specifically, the resultant model revealed a cyclical process: of learning, identity development and progress at transition. Inception of the process is characterised by immersion in the post-transition environment during the pre-transition phase, in which significant observational learning occurs via the use of more senior role models. This process leads to the identification of discrepancies between the actual (or junior) and ideal (or senior) self. This promotes a period of adjustment in which the behaviours relevant to senior status are incorporated within the self, bringing about a sense of readiness, or ability to cope with the transition. In essence, the athletes had sought to structure their pre-transition environment to represent that which they would encounter post-transition, thereby generating stability for their self-identity. The modification of identity, through the adjustment of behaviours and roles, predicted a competitive breakthrough, at which point the athletes began to think about the subsequent step at senior level, and hence the cycle of immersion, learning and adjustment continued.

The purpose of this study was to determine whether coaching behavior preferences of NCAA Division I athletes differ as a function of gender and type of sport. The Coaching Behavior Questionnare (CBQ; Martin & Barnes, 1999) was administered to 195 NCAA Division I athletes. Gender and sport type were the independent variables and the participant's mean scores for the subscales on the CBQ were the dependent variables. Descriptive statistics revealed that, overall, NCAA Division I athletes prefer positive and instructional behaviors more than non-responses or negative behaviors. A 2 (gender) x 3 (type of sport) MANOVA and follow-up discriminant function analysis indicated that coaching behavior preferences differed as a function of gender and type of sport played. Thus, NCAA Division I coaches should consider both individual and situational characteristics when working with their athletes to achieve the desired outcome.

The problem of this study was to search for possible effects of the pre-competition meal. This problem had two primary facets: 1) to determine performance scores secured by college varsity track and field men under two different pre-competition meal conditions and to study the relationship of the meal last ingested before competition to the scores; 2) to determine the concern for certain psychological and psycho-physiological factors under each of the two pre-competition meal conditions.

This investigation was designed to study coach and self-appraised groupings of intercollegiate tennis players who yield to stress and withstand stress and to determine if personality differences existed between groups. Subjects were 75 intercollegiate tennis players from Texas. A stress inventory and the Cattell Sixteen Personality Factor Questionnaire were instruments utilized in the study. Data were subjected to hierarchical profile-groupings, three-way analyses of variance, and a correlational analysis. Conclusions of the study were that intercollegiate tennis players and male and female players respond to stress differently; intercollegiate tennis players and male and female players who experience different levels of stress have different personalities; and players and coaches do not evaluate the ability to cope with stress similarly.

This study was designed to determine if differences exist between the personalities of injured and non-injured athletes, injured and non-injured athletes in individual sports, and injured and non-injured athletes in team sports. Subjects were forty-three female athletes selected from six intercollegiate teams. The test instrument was the Cattell Sixteen Personality Factor Questionnaire. Data were analyzed by the two-way analysis of variance. Alpha was .05. Conclusions of the investigation were that the personality of injured athletes does not differ from the personality of non-injured athletes, that non-injured athletes in individual sports are more self-assured than non-injured athletes in team sports, and that the personality of athletes in team sports does not differ from the personality of athletes in individual sports.
