Position-related differences in volume and intensity of large-scale cyclic movements of male player in handball

The aim of this study was to idetify the differences in volume and intensity of large-scale cyclic movement activities performed by handball players in different playing positions-backcourt players, wing, pivots and goalkeepers. For this purpose six eksperimental model matches (2x20min), played by Slovenian male handball teams (youth, juniors and seniors), were analysed. The sample consisted of 84 players of twelve teams and was divided into four sub-samples by playing positions. The collection of data on the cyclic loading of players in handball match was based on the computer-aided automatic tracking method with the SAGIT system, based on computer vision methods. The output data on the cyclic movements obtained by the SAGIT program were processed by the selected descriptive methods in Excel and SPSS programmes. Statistically signifikant differences were registrated between the groups of players in different playing possitions in terms of average distances walked or run during matches (volume). The greatest total distance was covered by the wings (3, 855m), followed by the backcourt players (3, 432m) and pivots (3, 234) whereas goalkeepers ran the least (1, 753m). Differences also appeared in intensity of large-scale cyclic movements, that is in the percentage of time spent in all speed classes. In the first speed class statistically significant differences occurred among all groups-the goalkeepers spent the highest percentage of time (86%) here, followed by pivots(62%) and wings (58%). There were no statistically significant differences in the second speed class between the groups of wings(23%), backcourt players (25%) and pivots (25%) ; however, all groups differed from goalkeepers (11%). The highest percentage of time spent in the third speed class was that of wings (14%) and backcourt players (14%). Nevertheless, there were no statistically significant differences between them. Pivots (10%) and goalkeepers (2%) did not spend much time in third speed class, so statistically differences were registraterd for latter two and the groups mentioned before. In the fourth speed class statistically differences occured between all the groups of players. In this speed class the wings spent the most time (4%), followed by the backcourt players(3%) and pivots(2%), whereas the lowest percentage of time in this speed class was that of the goalkeepers (0.5%). There were statistically significant differences between all groups of players in terms of average speed of movement-the fastest were wings (1.60m/s), followed by the backcourt players (1.43m/s), pivots (1.34m/s) and goalkeepers (0.73m/s).
