“…These results correspond with the reports by Kunze et al [28], who, analysing the play of futsal goalkeepers in 13 matches of the Santa catarina championship in Brazil in 2012, showed that gaining the playfield mainly by passing the ball with the foot accounted for 40% of all actions taken by goalkeepers. It is worth adding that goalkeepers of 11-person teams present similar activity in these actions, as confirmed, among others, by Szwarc et al [36].…”

“…As a rule, these were situations in which the losing team built a 'castle,' and with the goal abandoned by the goalkeeper, it created a numerical advantage in the opponent's half. Actions aimed at scoring by the goalkeeper are characteristic of futsal and in principle do not appear in the game of 11-person teams [36,37]. The conducted research reveals that the examined players showed the highest effectiveness in keeping the ball (555 actions, with 97% effectiveness) and in preventing the creation of scoring situations (606 actions, with 96% effectiveness).…”

“…FIFA experts have already noticed the advantage in using offensive actions over the defence game after the change in the 11-player soccer rules -the back-pass rule [35]. Later scientific research proved that the goalkeepers' involvement in offensive actions was 3-4 times greater than in the defensive game [36][37][38].…”

Purpose. The aim of the study was to develop a model of the efficiency of actions of goalkeepers from top-level futsal teams. Methods. Goalkeepers' activity, successful activity, and effectiveness were estimated with the consideration of accomplishing the game objectives in offence and defence and of the changing match status. The study applied the method of observation. Data about the game were registered on a self-developed observation sheet. Overall, 62 games of 23 goalkeepers participating in 31 matches of the World and European championships and the UEFA Futsal cup played in years 2012-2015 were observed. Results. It was found that actions to gain the playfield with the ball (41% of all actions) and to prevent a loss of a goal (28.2%) dominated in futsal goalkeepers' game. Offensive actions accounted for 58% and defensive actions for 42% of all actions undertaken by the studied futsal goalkeepers in the observed matches. The examined competitors achieved the highest effectiveness in keeping the ball (97%) and in preventing scoring situations (96%). Conclusions. The created model mapping the top-skilled goalkeepers' actions allows improving the process of coaching players by referring their game to objective patterns.

“…More and more often, goalkeepers tend to cooperate with different players in all other positions and engage in offensive actions outside the penalty area (Szwarc, Lipińska, Chamera, 2010). This is related to the goalkeepers' necessity to perform a greater number of activities of variable intensity such as sprinting, low-, moderate-and high-speed running, jogging, walking and standing (Di Salvo, Benito, Calderón, Di Salvo, Pigozzi, 2008).…”

The study aimed to assess the total covered distance during a match, performance volume below and above the anaerobic threshold, as well as characterize physical activities of professional Bundesliga goalkeepers during soccer matches. 34 goalkeepers (606 observations) from all eighteen Bundesliga teams, who played in the 2014/2015 season were considered for the study. The performance of goalkeepers was analyzed with the use of the VIS.TRACK system. The variables measured included: total covered distance [km] in the whole match, the first half, and the second half; distance covered below and above the anaerobic threshold (4 m • s -1 ) [km]; and distance covered in six intensity ranges [km]. The total distance covered by the goalkeepers was 5.48 ±0.56 km. The distance covered by goalkeepers below the anaerobic threshold was 5.28 ±0.52 km, whereas the distance covered above the anaerobic threshold amounted to 0.21 ±0.09 km. The ratio between the goalkeepers' volumes of aerobic and anaerobic performance was 25:1. The total distance covered by goalkeepers in match play and the distances covered by goalkeepers below and above the anaerobic threshold (96.17% and 3.83%, respectively) indicate that during a match the goalkeepers undertake predominantly aerobic exercises.

“…Nároky na hru brankára sa nezvyšujú iba v obrannej fáze, ale hlavne v útočnej fáze. Môžeme konštatovať, že až 75 % herných činností brankára je útočných (Smith 2004;Szwarc 2010). Preto si dovolíme tvrdiť, že ďalšou z vývojových tendencií v hre brankára je zvýšenie počtu herných situácií, v ktorých musí hrať nohou, s čím úzko súvisí zakladanie útoku.…”

Univerzita Komenského v Bratislave, Fakulta telesnej výchovy a športu Abstrakt Vnútorné zaťaženie brankárov v tréningovom procese skúmame z pohľadu dosiahnutých hodnôt srdcovej frekvencie. Chceli sme rozšíriť poznatky o vplyve rozdielnych metodických foriem na vnútorné zaťaženie brankárov vo futbale a tým podporiť možnosti vylepšenia ich tréningového procesu. Predpokladali sme, že brankári budú dosahovať významne vyššie hodnoty srdcovej frekvencie počas prípravnej hry v hernom tréningu ako počas prípravného cvičenia v hernom nácviku. Sledovaný súbor tvorili šiesti brankári v kategórií mladšieho a staršieho dorastu (U16, U17, U19). Pomocou športtesterov POLAR PRO sme zistili vnútorné zaťaženie brankárov, ktoré sme spracovali kompatibilným softwarom POLAR Team 2. Následne sme získané údaje vyhodnotili Wilcoxonovým T-testom a Cohenovým r. Zistili sme významne rozdielne priemerné hodnoty srdcovej frekvencie v jednotlivých metodických formách (T = 0; p ≤ 0.05; r = 0.9), čím sme štatisticky aj vecne logicky potvrdili náš predpoklad.
