Globally, sport plays a significant role and forms part of every modern person’s life, irrespective of race, age, gender or ethnic group. Researchers on this topic increasingly focus on the early identification of talent and the development of the talent to ensure optimal performance. One of the most critical trademarks of human development is die correlation between age and physical ability. The primary reason why people participate in sport is to improve their level of participation and performance. Therefore every effort should be made to obtain a more scientific approach towards optimal sports performance, seeing that it is scientifically proven that it improves the effectiveness of a specific sport with regards to the selection and preparation of individuals and teams. In present time South African sport is still facing the challenge to successfully integrate previously disadvantaged communities and to select teams purely on merit. The use of scientific evaluation criteria in the selection process of teams can make a definite contribution to help solidify the selection principle of merit only. This is due to the fact that scientifically, assessed physical performance can not merely be ignored or overruled in the selection of teams. The primary objective of this study was first of all to establish whether different norms will be needed for different playing positions in netball and if the assessments that are currently used are able to accurately predict the highest level that players will be able to play at. In the second instance, the objective of this study was to try and determine which components should be part of a set of netball specific evaluation criteria. To accomplish this objective research was done to find many different test protocol and to find literature that would verify the protocol. A third objective was to identify the positional qualities that netball players have to comply to, based on the selected evaluation criteria, and to select the best tests to be used for talent identification. In other words what the minimum test requirements would be to accomplish maximum data gathering. The developed protocol consisted of three (3) motor tests, four (4) physical tests and three (3) kinanthropometrical tests. The research group used in this study consisted of 304 senior netball players i.e. players older than 19 years of age. These players were categorized into three groups, namely players competing at club, national and international level. With the presentation of the statistical analysis, percentile ranks were developed and a 100 research candidates per positional group was used; i.e. 300 netball players in total. Furthermore an ANOVA was used to determine whether there were significant differences between the three positional groups. An analysis was done to determine if the evaluation criteria could discriminate between players from different positional groups. The analysis was merely used as a classification method and did not serve to evaluate die significance of differences. The results delivered position-specific norms. A function for predicting the identification of talented and less talented players was also developed. Although the study showed certain limitations, the research can be utilized to further develop scientific talent identification criteria for netball and this will be to the advantage of sports scientists and coaches involved with netball. / Thesis (DPhil (Human Movement Science))--University of Pretoria, 2008. / Biokinetics, Sport and Leisure Sciences / DPhil / unrestricted

Abstracts in Afrikaans and English / Inklusiewe onderrig ondersteun die insluiting van alle leerders met verskillende behoeftes en vaardighede in klaskamers, wat baie keer te groot, of te verskillend vir doeltreffende onderrig is. Beweging as deel van ‘n vroeë leerervaring is noodsaaklik vir optimale neurale ontwikkeling. Dit beïnvloed organisasie en stimuleer die spesifieke neurologiese sisteme nodig vir optimale funksionering en ontwikkeling van die brein. Sensoriese integrasie disfunksie word gesien as die wortel van baie leerprobleme. Die vestibulêre sisteem is direk verbind met die sensoriese en motoriese sisteme. ‘n Sensoriese integrasie disfunksie het ‘n duidelike invloed op die vestibulêre sisteem. Die vestibulêre sisteem het baie interkonneksies met baie dele in die brein, byvoorbeeld propriosepsie en die tassisteem. Doeltreffende funksionering van die sensoriese, motoriese en vestibulêre sisteme word verlang vir ‘n hoë vlak van prestasieverrigting in sport en akademie. Wanneer die vestibulêre sisteem gestimuleer word, het dit ‘n direkte positiewe invloed op die sensoriese en motoriese ontwikkeling van leerders. Die doel van hierdie studie was om te bepaal wat die persepsie van grondslagfase-onderwysers en ouers is oor die rol en voordele wat vestibulêre oefeninge te weeg kan bring in die motoriese en sensoriese ontwikkeling van leerders. Leerders in graad 1 van ‘n privaatskool, asook van grade 2 en 3 van ‘n plaasskool is gekies as deelnemers in die studie. Die keuse van leerders was op grond van die bereidwilligheid van hulle en hul ouers om aan die studie deel te neem. Leerders het ‘n vestibulêre oefenprogram drie maal per week gedoen vir die tydperk van agt weke. Observasie-vraelyste is deur onderwysers en ouers ingevul na afloop van die derde sessie elke week. Vir die vraelys het ouers en onderwysers gekyk na die verbetering in aandagspan, konsentrasie, luistervaardigheid, oogkontak, sosiale interaksie en samewerking. Onderhoude is met ouers en onderwysers gedoen na aanleiding van die observasievraelyste wat vir die agt weke voltooi is. Transkripsies van die onderhoude is gedoen en afleidings is gemaak deur analise van die observasie-vraelyste en die getranskribeerde onderhoude. Al ses die ontwikkelingsareas by beide skole het verbetering getoon oor die agt weke. Dit dui daarop dat vestibulêre oefeninge wel ‘n invloed op die sensoriese en motoriese ontwikkeling het. / Inclusive education promotes the inclusion of learners with different needs and capabilities in classes which are often too big and diverse for effective teaching. Movement as an early learning experience is necessary for optimal neural development. It influences organisation and stimulates the specific neurological systems required for optimal functioning and development of the brain. Sensory integrative dysfunction is believed to be at the root of many learning disorders. The vestibular system is directly connected with the sensory and motor systems. The vestibular system will be directly affected when a sensory integrations dysfunction presents. In fact, the vestibular system has many interconnections with almost every other part of the brain like proprioception and the tactile system. Proper functioning of the sensory, motor and vestibular systems is required for higher level performance in sport and academics. When the vestibular system is stimulated, it will result in a positive influence on the sensory and motor development of learners. The aim of this study is to determine the perceptions of foundation phase teachers and parents regarding the role or benefits of vestibular exercises in promoting learners’ motor and sensory development. Learners in Grade 1 of a private school and Grade 2 and 3 learners of a farm school in the northern Free State were selected as participants in the research. Learners were selected on the basis of the willingness of them and their parents to participate in the research. The participants did exercise sessions three times a week for thirty minutes over a period of eight weeks. Observation sheets were completed for all eight weeks, for the duration of the exercise program, by teachers and parents. These sheets were completed weekly after the third sessions in that week. The observation sheets listed concentration, attention span, listening, eye contact, cooperation, social interaction and self-esteem as developmental areas. Interviews were done after the period of eight weeks with the parents and teachers. The interviews conducted with both parties were taped and meticulously transcribed. This helped the researcher to get a better understanding of the study and to analise data and draw conclusions.All six areas of development showed improvement at both schools over the period of eight weeks. This indicates that stimulating the vestibular system promotes sensory and motor development. / Inclusive Education / M. Ed. (Inklusiewe Onderwys)
