Former research of sports vision has focussed on investigating the role of the central vision and the gaze behaviour whereas peripheral vision has been left in the shadow. Ecological dynamics and the information processing theories have fundamental differences in how perception and action are coupled. Elite athletes can extract sport-specific useful peripheral information more accurately and efficiently than lesser-skilled athletes or novices. Perceptual-cognitive interventions have successfully improved athletes\u2019 peripheral perception, but it has not been connected to improved sports performance. There is no common understanding of how peripheral perception should be trained to gain transfer effects in sports performance. Thus, the purpose of the study was to investigate the useability of the information processing approach to train peripheral perception off-court using non-sport-specific stimuli.\nNine intermediate basketball players were recruited to participate in the study. The study included pre-tests, placebo control period, mid-tests, peripheral training intervention and post-tests. Both study periods lasted for four weeks. Four peripheral reaction tests, visual field size tests, basketball skill tests and from the basketball transfer test (Pick and Roll), gaze location and decision accuracy were collected before and after intervention periods. Participants went first through the placebo control period followed by the peripheral training intervention. Peripheral training intervention, twice 30 minutes per week, included peripheral stimuli identification, attention allocation and multiple object tracking combined with correct motor response and/or sport-specific task.\nAfter the placebo control period significant increase (p<0,001) occurred in the horizontal visual field size and performance significantly improved (p<0,05) in two basketball skill tests. After peripheral training intervention, total simple reaction times decreased significantly (p<0,05) and a decrease in reaction time also occurred in the other two reaction tests, but insignificantly. The number of peripheral decisions made compared to foveal decisions increased in post-test, but insignificantly.\nThe off-court generic peripheral training used in the present study does not seem to improve basketball offence performance. Reaction time results suggest peripheral training might improve reaction speed to non-sport-specific peripheral stimuli. Peripheral training potentially shifted participants to use peripheral perception in the decision-making process with no decrements in overall basketball on-court performance. More intervention studies investigating peripheral perception training\u2019s effects on sports performance are needed.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-03-16T09:55:22Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-03-16T09:55:22Z (GMT).
