Thesis (M Sport Sc (Sport Science))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The purpose of this study was to determine the impact of participation in a small group-based perceptual-motor training programme on the gross motor and visual-motor integration skills of children who show signs of Developmental Coordination Disorder (DCD). Two physical education teachers selected 22 children for assessment as potential participants for this study. The Movement ABC (M-ABC) was then administered to this group and the eight children who scored the lowest were invited to volunteer for this study. These children all volunteered and then completed the assessment of their visual-motor integration skills as measured by the Developmental Test of Visual Perception (DTVP-2). The study followed an evaluative case study design in which changes in the gross motor and visual-motor integration skills of each participant were reported and interpreted individually. The six-week intervention programme was focused on developing the perceptual-motor link between throwing, catching and balancing skills with challenges to visual skills development, especially eye-hand coordination. A comparison of pre-test, post-test and retention test scores in the M-ABC revealed that the programme had a positive effect on six of the children. The results for the seventh child were inconsistent on each test occasion, leading to the conclusion that he may have a co-morbid disorder related to attention. Improvements in static balance were noted and some children also experienced improvements in their ball skills (aiming and coincident timing) which brings the researcher to the conclusion that the programme was effective for gross motor development. DTVP-2 results showed improvements in eye-hand coordination in five of the seven children. According to the VMI quotient score, only one child improved, one deteriorated and the rest showed no change which brings the researcher to the conclusion that the intervention programme was not effective for visual-motor integration. / AFRIKAANSE OPSOMMING: Die doel van die studie was om die impak te bepaal van deelname in „n klein-groep gebaseerde perseptueel-motoriese oefenprogram op die groot motoriese en visueel-motoriese integrasievaardighede van kinders met tekens van die Ontwikkelingskoördinasie-afwyking (DCD). Twee Lewensoriëntering-onderwysers het 22 kinders geïdentifiseer vir assessering as potensiële deelnemers aan die studie. Hierdie groep het die Beweging-ABC toets (M-ABC) ondergaan en die agt deelnemers met die laagste uitslae is uitgenooi om aan die studie deel te neem. Hierdie agt kinders het ingestem en daarna is die assessering voltooi deur hulle visueel-motoriese integrasievaardighede te meet deur middel van die Ontwikkelingstoets vir Visuele Persepsie (DTVP-2). Die studie het „n evaluerende gevallestudie-ontwerp gevolg waarin die veranderings tussen die groot motoriese en visueel-motoriese integrasievaardighede van elke deelnemer individueel geïnterpreteer en gerapporteer is. Die ses week-intervensieprogram het gefokus op die ontwikkeling van die perseptueel-motoriese skakel tussen gooi-, vang- en balans-vaardighede met uitdagings vir die ontwikkeling van visuele vaardighede, veral oog-hand koördinasie. „n Vergelyking tussen die voor-, na- en opvolgtoetse van die M-ABC se toetstellings het getoon dat die program „n positiewe effek op ses van die kinders se groot motoriese vaardighede gehad het. Die uitslag van die sewende kind was teenstrydig tydens elke toetsgeleentheid en dit het gelei tot die gevolgtrekking dat hy moontlik aan „n addisionele afwyking mag ly wat verband hou met „n aandagprobleem. Verbeterings in statiese balans is waargeneem en sommige kinders het ook „n verbetering in balvaardighede getoon (akkuraatheid en reaksietyd). Volgens die DTVP-2 resultate was daar verbeterings in oog-hand koördinasie by vyf van die sewe kinders. Volgens die VMI-kwosiënttelling het slegs een kind verbeter, een het versleg en die ander vyf het geen verandering getoon nie. Die navorser kom dus tot die gevolgtrekking dat die intervensieprogram nie effektief is vir visueel-motoriese integrasie nie.

Thesis (M Sport Sc (Sport Science)-- University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The purpose of this study was to determine the effects of a perceptual-motor training programme on the coincident anticipation timing and batting performance of university club cricket players. The intervention programme focused on developing players‟ visual attention and concentration. Vickers‟ (2007) Three-Step Decision Training Model was used to structure the training sessions. The study followed a repeated measures experimental design with three groups (experimental, placebo, and control) formed by volunteers from a university club cricket team. The independent variable was a four-week training programme. The dependent variables were coincident anticipation timing and performance on a cricket batting test. Subjects were pre- and post-tested with retention tests occurring after a set period of “no training” following the post-tests. Differences between groups were compared using Kruskal-Wallis ANOVA by Ranks Tests. Differences within each group were compared using multiple Mann-Whitney U-Tests. No significant improvements were observed in the experimental group‟s coincident anticipation timing and batting performance. Although neither coincident anticipation timing nor batting performance significantly improved, further research into the use of Vickers‟ (2007) Model to enhance sport performance is recommended. / AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om die uitwerking van ʼn perseptueel-motoriese opleidingsprogram op die samevallende vooruittydsberekening (“coincident anticipation timing”) en kolfprestasie van universiteitsklubkrieketspelers te bepaal. Die klem van die intervensieprogram het op die ontwikkeling van spelers se visuele aandag en konsentrasie geval. Die opleidingsessies is volgens Vickers (2007) se drieledige model vir besluitnemingsopleiding saamgestel. Die studie het ʼn eksperimentele ontwerp van herhaalde metings op drie groepe (eksperimenteel, plasebo en kontrole) van ʼn universiteitsklubkrieketspan toegepas. Die onafhanklike veranderlike was ʼn vier weke lange opleidingsprogram. Die afhanklike veranderlikes was samevallende vooruittydsberekening, en prestasie in ʼn krieketkolftoets. Proefpersone het voor en net ná die opleiding toetse ondergaan, sowel as behoudtoetse drie weke ná die na-opleidingstoetse. Verskille tussen groepe is met behulp van rangtoetse uit Kruskal-Wallis se variansie-analisemodel (ANOVA) bepaal, terwyl verskille binne groepe met veelvuldige Mann-Whitney-U-toetse vergelyk is. Geen beduidende verbetering is in die eksperimentele groep se samevallende vooruittydsberekening of kolfprestasie waargeneem nie. Hoewel nóg samevallende vooruittydsberekening nóg kolfprestasie aansienlik verbeter het, word verdere navorsing oor die gebruik van Vickers (2007) se model vir die verbetering van sportprestasie aanbeveel.
