Abstract:

Video materials have been used as teaching tools for the acquisition of structural characteristics, which is one of the most important segments of motor learning in sports. Different video devices allowed different ways of implementing video materials and accordingly, improve the quality of teaching and learning process. The purpose of this study was to determine whether the different playback speed of videos affects learning about the structural characteristics of different basic ski elements. In this study, three ski elements were recorded using Panasonic Lumix FZ1000 and Gopro 360 max cameras. Each footage was edited using Kinovea and Da Vinci resolve software programs to slow down the speed and focus on a moment when the structural position was best represented. The sample of this study consisted of 151 students (107 male and 44 female) from the Faculty of Kinesiology Osijek. The structural analysis was presented to all participants using various video recordings. In a short presentation, all necessary information about the structural characteristics of all three ski elements was explained to the students. All the video material was shown in the presentation. While completing the ski questionnaire, all of the video materials were available to the students. After completing the ski questionnaire, students had to rate the usefulness of each video. The average score that students achieved on the ski knowledge test was 8.9 ± 2.48 points (74.16 ± 0.21%). The usefulness of video materials were recorded with the Panasonic Lumix FZ1000 at normal speed was 3.01 ± 1.25 and 3.67 ± 1.12 for slow motion video. The usefulness of video materials recorded with the Gopro 360 max and presented at normal speed was 3.79 ± 1.06 and 4.34 ± 0.96 for slow motion video. The differences between normal and slow motion videos were statistically significant for both devices (p < 0.01). The obtained results show that the speed of video playback of ski elements significantly improves the perception of the required structural characteristics. Considering the better effect of slow motion videos during the education of future skiers, a higher number of frames per second should be considered when selecting a video device to improve the quality of slow motion video material.
