Position-related differences in volume and intensity of large-scale cyclic movements of male players in handball
The aim of this study was to identify the differences in the volume and intensity of large-scale cyclic movement activities performed by handball players in different playing positions - backcourt players, wings, pivots and goalkeepers. For this purpose six experimental model matches (2x20min), played by the Slovenian male handball teams (youth, juniors and seniors), were analysed. The sample consisted of 84 players of twelve teams (average age 20.26 ± 4.28yrs; average height 182.51 ± 6.59cm; average body mass 80.61 ± 10.37kg) and was divided into four sub-samples by playing position. The collection of data on the cyclic loading of players in a 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 programme were processed by the selected descriptive statistics methods in Excel and SPSS programmes. Statistically significant differences were registered between the groups of players in different playing positions 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 (3,234m), whereas goalkeepers ran the least (1,753m). Differences also appeared in the intensity of large-scale cyclic movements, that is in the percentage of time spent in all the speed classes. In the first speed class statistically significant differences occurred among all the groups - the goalkeepers spent the highest percentage of time (86%) here, followed by the 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 three groups differed from the goalkeepers (11%). The highest percentage of time spent in the third speed class was that of the 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 the third speed class, so statistically significant differences were registered for the latter two and the groups mentioned before. In the fourth speed class statistically significant differences occurred 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 the groups of players in terms of average speed of movement - the fastest were the wings (1.60m/s), followed by the backcourt players (1.43m/s), pivots (1.34m/s), and goalkeepers (0.73m/s).
