Improving the athletic performance of highly skilled college volleyball players through the use of a videotape treatment packageLowe, Steven Keating 01 January 1981 (has links)
A multiple baseline across behaviors design was used to test the effectiveness of a treatment package involving the use of a videotape recorder to improve the performance of college women volleyball players. The subjects were four highly skilled athletes, as evidenced by thei.r participation in the University of the Pacific volleyball program, ranked second nationally during the 1980-81 season. The treatment package consisted of the following: (a) zooming in with a video camera on particular aspects of the players' performances; (b) attempts to change only one aspect of the performance of a skill rather than the entire skill; (c) cueing and corrective feedback provided by the coach during the players' viewing of the resulting videotapes; (d) the players immediately correcting their errors in performance after viewing the videotapes and (e) multiple viewings by the players of videotapes of their correct performances of the volleyball skills. The results indicated that all of the subjects benefited from the videotape treatment package. Two of the players showed improvement in the two volleyball skills for which the treatment was given. The other two players showed improvement in one of the two volleyball skills for which the treatment was given. For three of the four players their improved practice performances with the videotape treatment also resulted in improved performances during scrimmages for at least one of the two target behaviors.

Video analysis as a form of feedback to improve sport performanceThomas, Brendan Nigel 12 1900 (has links)
Thesis (MScSportSc)--Stellenbosch University, 2004. / ENGLISH ABSTRACT: Feedback is critical for motor skill learning. Knowledge of performance (KP) In
the form of verbal feedback is the most commonly used type of augmented feedback.
Advances in technology have made it possible for coaches to utilise video-supported
feedback with athletes with the intention of accelerating the learning process. The use of
videotape replay has been an effective aid under some circumstances. Recent
commercially available products offer digital analysis that may be even more successful
than ordinary video replay in this regard.
The purpose of this study was to determine the effectiveness of knowledge of
results (KR) and verbal KP with video-support in improving the learning of the tennis
serve, when compared to KR with verbal KP only. A total of 18 adults (lOwomen and 8
men) were assessed on their serving technique (6 kinematic variables), accuracy
(2 variables) and speed (1 variable). Technique analysis was completed using a
commercially available analysis programme. For a short intervention period, one group
(n = 10) received KR with verbal feedback only, while the other group (n = 8) received
KR plus verbal feedback with video support. The subjects were tested after the
intervention to see what changes had occurred with regards to the speed, accuracy and
technique of their serves. No significant differences were found for any of the variables,
leading to the conclusion that the amount oftime spent in the intervention programme
must be extended in order to possibly achieve significant effects on performances. / AFRIKAANSE OPSOMMING: By die aanleer van motoriese vaardighede is terugvoer van kritiese belang.
Verbale terugvoering is die mees algemene vorm van kennis oordraging aan die
uitvoerder. Verbetering in tegnologie het dit nou moontlik gemaak vir afrigters om videoondersteunde
terugvoer met atlete te gebruik, met die doelom die leerproses te versnel.
Die gebruik hiervan is in sekere situasies 'n effektiewe hulpmiddel. Kommersiële
produkte wat tans beskikbaar is bied die moontlikheid van digitale ontledings, wat dalk
meer suksesvol kan wees as slegs die terugspeel van 'n video aan die uitvoerder.
Die doel van hierdie studie was om die doeltreffendheid van kennis van resultate
(knowledge of results) en verbale terugvoering met video-ondersteuning in die
verbetering van die tennis afslaan te meet, en dit dan te vergelyk met kennis van resultate
waar net verbale terugvoering verskaf is.
'n Totaal van 18 volwassenes (It) vroue en 8 mans) se afslaantegniek (6
kinematiese verandelikes), akkuraatheid van afslaan (2 verandelikes) en die spoed van die
afslaan (1 verandelike) is nagegaan. Tegniekontleding is met die gebruik van 'n
komersieël beskikbare analise-program gedoen. Een groep (n = l O) het kennis van
resultate en verbale terugvoer gekry vir 'n kort intervensie periode. Die ander groep (n =
8) het kennis van resultate en video-ondersteunde verbale terugvoer, ook vir 'n kort
intervensie tydperk ontvang. Die deelnemers is na afloop van die intervensie tydperk
getoets om te bepaal watter veranderinge met betrekking tot spoed, akkuraatheid en
afslaantegniek plaasgevind het.
Geen beduidende verskille is in enige van die verandelikes gevind nie. Dit gee
aanleiding tot 'n gevolgtrekking dat die duur van die intervensieprogram verleng moet
word om 'n beduidende effek op uitvoering te kry.
