Dissertation submitted to the Faculty of Health in partial compliance with the requirements for the Masters Degree in Technology: Chiropractic, Durban University of Technology, 2009. / Objectives: To determine the prevalence and risk factors of amateur outdoor and indoor volleyball players in a KwaZulu-Natal North Coast region. Methods: The location of the study was the KwaZulu-Natal North Coast region, which includes two of its districts, viz, Tongaat (Indoor) and Kwa Dukuza (Outdoor). A total of 115 out of a possible 160 volleyball players participated in this study which comprised of 68 outdoor and 47 indoor players. The answering of the questionnaires was done on separate days for both the districts. On the allocated days, they were given a letter of information (Appendix B) to read and the questionnaires (Appendix C) to answer. Participation in the study was voluntary and consent was given by filling in the questionnaire. The researcher was present on this day to supervise and to collect the completed questionnaires immediately after the session was completed. Results: Out of a total of 115 participants, 79 (68.7%) of the participants sustained an injury due to volleyball. According to results found in this study, the knee, ankle and shoulder were the most frequently injured sites. 79 Participants reported to have sustained an injury, 67 participants reported to have a present injury and 60 participants reported a worst injury. The knee was found to be the most injured site in both the outdoor and indoor participants, followed by the ankle. The results in this study show that the use of protective gear can help minimise injury rates. 6 Conclusion: The prevalence and risk factors of amateur outdoor and indoor volleyball players in a KwaZulu-Natal North Coast region has been discussed in this study. With regards of number of injuries, the results have shown that there is no significant difference between outdoor and indoor volleyball players. In terms of the site of injuries, the lower limb was affected the most in comparison to the rest of the body. Results in this study have shown that outdoor players sustained more knee injuries whilst indoor players showed a high number of ankle injuries.

TITLE: The development of voleyball rules and its influence on the gameplay and combinations ABSTRACT: The goal of my thesis is to study the influence of changes in volleyball rules on the developement of game systems and game combinations. In this paper I will attempt to answer and discuss the following scientific question: What influence have changes of the volleyball rules had on the developement of game systems and game combinations. I will chart the developement of volleyball rules from 1950 until present. I will study how the parametres of the playing field and its surroundings have changed. I will chart the developement of volleyball equipment, mainly the volleyball net and the ball. Based on studying the changes of volleyball rules, I will compare the developement of game systems and game combinations. I will compare the lengths of the games based on the changes of the rules. KEY WORDS: Volleyball, the rules of volleyball, game combinations in volleyball, game systems in volleyball.

The purpose of this study was to identify and explain the dynamics involved in dyadic sport teams, as well as to differentiate dyads from larger teams. Semi-structured individual interviews consisting of open-ended questions were conducted with seven beach volleyball athletes. Cote', Salmela, and Russell's (1995) guidelines were used to inductively analyze and interpret the qualitative data. The results of the analysis revealed three higher-order categories concerning the dyadic relationship: (a) the sport environment, which included elements related to beach volleyball and an athletes' participation in it, the challenges a partnership sport presented, as well as comparisons between partnerships and other sports, (b) dyad structure and composition, which included elements that allowed a dyad to function and the importance of creating a sense of balance in the partnership, and (c) the dyadic interaction process, which focused on developing communication and cohesion in the partnership, and working towards an ideal state where interaction was efficient and effective, culminating in peak performance and a meaningful relationship. The results of the study have advanced the knowledge of group dynamics by differentiating the dyad from larger teams.

Motor learning and attentional focus have been examined quite extensively; however, results regarding the best type of attentional focus for novice learners are equivocal. The purpose of the current study was to determine which type of attentional focus is most beneficial over extended practice phases when learning the complex skill of the volleyball serve. Three novice learners who had no prior formalized training in the sport of volleyball completed 240 service trials over eight days after an initial baseline phase. A single-subject design with alternating treatments was employed in this study. After receiving initial instructions, each participant served three blocks of 10 serves scored on a four point system based on that used by Wulf and colleagues (2002). After baseline scoring was established, the participants were given either external or internal focus instructions. The type of instructions that were given to the participants alternated every 60 serves and the order of the treatments was counterbalanced across participants. The participants completed a total of 120 serves using each type of focus. Visual inspection of the results, as well as the effect size of both types of instructional statements, revealed no clear trends for any of the participants. This study expanded the breadth of research in the field of attentional focus and will aid future studies examining the effects of attentional focus on the acquisition of sport specific skills. / School of Physical Education, Sport, and Exercise Science
