Many sports itself demand efficient anticipation that offers usually more time for the decision making, in which the visual perception skills have the largest role. The purpose of this study was to clarify the effect of the video training in developing perceptual-cognitive and anticipation skills in tennis, and furthermore, to compare the effectiveness of two different instruction methods in developing anticipation skills.\n\nA total of 35 PE students were recruited from their tennis course to participate in the experiment. All were physically active students with comparable levels of sporting experience. Participants were divided into four groups. Each group of participants completed the pre- and post-tests. Three of the groups took part in the tennis training and one maintained as control group. Two of the training groups also underwent 4 x 20 min of laboratory-based perceptual video training followed with explicit or guided discovery instruction and feedback to develop their anticipation skills. Eye movements were recorded with ASL Eyelink 5000SU system and with Dartfish Team Pro 4.5. The results were analysed using the t-test and a factorial analysis of variance (ANOVA) with the IBM SPSS 19.0 software.\n\nPlayers who received perceptual training improved statistically significantly their performance on laboratory based reaction test compared with control group and other training group. Also the eye movement analyses showed statistically significant results for the video training groups in number of fixations and the mean number of fixation locations between the pre- and post-test. In addition, there were some positive changes in the mean averages and decrease of the standard deviations, but these did not reach the statistical significance.\n\nAs expected, the video training groups completed their reaction tests faster than other groups. This can be seen as important anticipation factor for the decision making which helps player to be in the right time in the right place for executing the technical response. The tennis training course itself can reduce the reaction time and the additional video training benefits even more. The eye movement analysis didn\u00b4t show any significant results between the groups even though they encourage the use of video training and targeted instruction for developing anticipation skills. Research cannot show statistically significant results between the two instruction models but explicit model can offer better results in anticipation for the short term period.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Tuomas Mikkola (tukamikk) on 2015-06-11 08:43:44.667330.
