Title: Visual constrains and feedback in the badminton serve Objectives: The aim of this thesis was to investigate the effect of short serve feedback constraints in badminton players. Methods: The data were experimentally collected. Twelve players underwent measurement of backhand serve. Every player performed four series of 20 serves. First and fourth were played with occlusion, second and third in normal conditions. Their results were recorded on a video camera and then evaluated by indirect analysis. Results: Overall, the players recorded an average distance of the shuttlecock impact point from the service line in the occluded conditions of 40,7±22,2 cm in the normal conditions of 25,2±17,9 cm. These results showed a significant effect of occlusion on short backhand serve t(9)=4,98, p<0,001 and with a strong effect of d=1,44. Out of 960 total backhand serves, 63 were ruled out. Players played 11 outs in occluded conditions, 52 in normal conditions. Keywords: visual perception, occluded vision, motor skills, proprioception, game performance Názov: Omezení zpětné vazby při podání v badmintonu Ciele: Cieľom tejto diplomovej práce bolo zistiť, aký vplyv má obmedzenie spätnej väzby na krátke podanie u hráčov bedmintonu. Metódy: Dáta boli získavané experimentálne. Dvanásť hráčov podstúpilo meranie krátkeho bekhendového podania. Každý hráč odohral štyri série po 20 podaní. Prvá a štvrtá séria prebiehala so zatemnením, druhá a tretia v normálnych podmienkach. Ich výsledky boli zaznamenané na videokameru a následne vyhodnotené na základe nepriameho pozorovania. Výsledky: Hráči celkovo zaznamenali priemernú vzdialenosť bodu dopadu košíka od čiary v podmienkach so zatemnením 40,7±22,2 cm v normálnych podmienkach 25,2±17,9 cm. Tieto výsledky preukázali signifikantný vplyv zatemnenia na krátke bekhendové podanie t(9)=4,98, p<0,001 a so silným účinkom d=1,44. Z 960 celkových podaní dopadlo do autu 63. V podmienkach so zatemnením zahrali hráči 11 autov, v normálnych podmienkach 52. Kľúčové slová: vizuálne vnímanie, zatemnenie, motorika, propriocepcia, herný výkon
Keywords: game performance; motor skills; occluded vision; proprioception; visual perception; herný výkon; motorika; propriocepcia; vizuálne vnímanie; zatemnenie
