Visual constrains and feedback in the badminton serve
Ďurčo, Dominik ; Carboch, Jan (advisor) ; Pravečková, Petra (referee)
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

Visual constrains in badminton serve
Ďurčo, Dominik ; Carboch, Jan (advisor) ; Petružela, Jan (referee)
Title: Visual constrains in badminton serve Objectives: Main goal of this bachleor's theses was to examine whether and to what extent does the visual feedback influences short badminton serve, whether the accuracy and success rate will change. Methods: Data were obtained experimentally, later evaluated by the method of indirect observation - video analysis. Ten players were tested. Each player was subjected to four tests. The first serve test was with occlusion, the player's vision was occluded at the moment of contact of the shuttlecock with the racket using the occlusion glasses that the players wore. The second and third tests were performed under normal conditions. The last test was the same as the first test with occlusion. Results: By comparing the average distances of the shuttlecock impact points between the short backhand serve tests in badminton, a statistically significant effect of visual feedback p = 0.04 on the accuracy of short serve was demonstrated. In the occlusion tests, the average distance between the line and the point of impact of the shuttlecock was 32.5 ± 23.9 cm and under normal conditions 27.7 ± 20.8 cm. The difference between number of fouls under two conditions was only 1.5%, with more foul attempts being recorded in the tests under normal conditions. Keywords:...
