Analysis of the difference in the performance of the repeated sprint ability and the change of direction in futsal with and without driblling ball

Za futsal je karakteristično da postoji veliki broj visokointenzivnih aktivnosti i cilj je da se sportaš akumulira što manje umora. Cilj rada je bio utvrditi razlike u rezultatima u sposobnosti ponavljanja sprinteva i promjene smjera kretanja sa i bez vođenja lopte kod futsal igrača. Korištena su dva testa za sposobnost ponavljanja sprinteva koji su bili MBI300m, taj test se izvodi na način da sportaš trči 20m 15 puta sa promjenom smjera kretanja dok je drugi test MBI240PSK koji se izvodi na način da sportaš trči 8 puta 40m sa promjeno smjera kretanja te ima 20sek pauze. Testovi za promjenu smjera kretanja su bili MAGT (T – test) i MAG90K (9 3 6 3 9). Istraživanje je provedeno na 13 igrača futsala juniorskog uzrasta (AS±SD, 18±0,71 god) . Rezultati su analizirani putem T – testa te je dobiveno da postoji statistička značajna razlika u rezultatima kod svih testova sa i bez vođenja lopte. Dobiveni rezultati koje nisu bili statistički značajni su %MBI240PSK koja označuje postotak opadanja brzine trčanja sprinteva gdje nema statističke značajne razlike sa i bez vođenja lopte. Također analizirajući opadanja brzine trčanja svakog pojedinog sprinta nije dobivena statistički značajna razlika između drugog sprinta bez lopte sa drugim sprintom sa loptom i tako sve do osmog sprinta bez i sa loptom. Vođenje lopte povećava energetsku potrošnju sportaša za vrijeme submaksimalnih aktivnosti što objašnjava dobivene podatke. U testiranje futsal igrača trebalo bi uvrstiti i testove sa vođenjem i bez vođenja lopte. U testovima sa vođenjem lopte najbolje rezultate su imali igrači koji spadaju u prvu četvorku testirane ekipe te može biti pokazatelj tehničke kvalitete igrača. Testiranje bez vođenja lopte je nužno jer se utvrđuju parametri kondicijske pripremljenosti.Futsal is characterized by a large number of high-intensity activities, and the goal is for the athlete to accumulate as little fatigue as possible. The aim of the work was to determine the differences in results in the ability to repeat sprints and change the direction of movement with and without dribbling the ball in futsal players. Two tests were used for the repeated sprint ability, which were the MBI300m (15*20m), which is performed in such a way that the athlete runs 20m 15 times with a change of direction of movement, while the second test is the MBI240PSK (8*40m), which is performed in such a way that the athlete runs 8 times for 40m with a change of direction of movement and has 20 seconds rest. The tests for change of direction were MAGT (T – test) and MAG90K (9 3 6 3 9). The research was conducted on 13 junior futsal players age ( 0,71). The results were analyzed using the T-test, and it was found that there is a statistically significant difference in the results of all tests with and without dribbling the ball. The variables that were not statistically significant are %MBI240PSK, which indicates the percentage of which sprint decrements where there is no statistically significant difference with and without guiding the ball. Also, analyzing the decrease in speed of each individual sprint, no statistically significant difference was obtained between the second sprint without the ball and the second sprint with the ball, and so on until the eighth sprint without and with the ball. Driving the ball increases the athlete's energy consumption during submaximal activities, which explains the obtained data. In the testing of futsal players, tests with and without guiding the ball should be included. In tests with ball handling, the best results were obtained by players who belong to the first four of the tested team, and this can be an indicator of the technical quality of the players. Testing without driving the ball is necessary because the parameters of fitness preparation are determined
