The purpose of this study was to compare aerobic capasities and recovery times according to playing positions of elite male football players. For this reason, twenty-four professional football players who played in Trabzonspor participated in voluntarily to this study. According to playing positions, players were divided to four different groups as three goalkeepers (age: 26,0 ± 2,64 years; height: 188,8 ± 2,88 cm; weight: 79,6 ± 5,13 kg), eight defencive players (age: 27,1 ± 2,69 years; height: 183,5 ± 5,12 cm; weight: 76,3 ± 3,06 kg), eight midfield players (age: 25,8 ± 1,64 years; height: 178,5 ± 8,79 cm; weight: 75 ± 7,63 kg) and five forward players (age: 28,0 ± 1,87 years; height: 181,8 ± 4,81 cm; weight: 73,4 ± 3,78 kg). The football players applied Yo-Yo Intermittent Recovery Level-1 (Yo-Yo IR1) which was a field test and recovery times, maximal oxygen consumption, maximal heart rates, and covered distances of players values were examinated according to positions of players. Kruskal Wallis-H test was used to determine significant difference between groups. According to test results, there is a significant difference (p < 0.05) between recovery times, maximal oxygen exhaustion values, maximal heart beating numbers, and covered distances according to playing positions of male football players is statistically obtained. The differences between groups was determined with Mann Whitney-U analyze technique. According to test results, it was found that the covered distances (1987,5 ± 260,3m) and maximal oxygen consumption values (53,0 ± 2,17 ml/kg/dk) of midfield players was greater than players who played in other positions. The forward players had better recovery time values (3,38 ± 0,6 dk) than players who played in other positions while goalkeepers had lower maximal heart rate (179,3 ± 8,50 atım/dk) than players who played in other positions. As conclusion, it was statistically determined that aerobic power performance and recovery times of elite male football player was differentiated according to position of football players.

In this study was aimed to compare according to playing positions of revovering times and aerobic capacity at thepreparatory period and competition season (after 8 weeks) in elite soccer players. For this reason, 24 professional football players(age: 26.7±2.2 years; height: 182.1 ±6.8 cm; body mass: 75.7±5.3 kg) who played in Trabzonspor were divided to four differentgroups as 3 goolkeepers (age: 26.0±2.64 years; height: 188.8±2.88 cm; body mass: 79.6±5.13 kg), 8 defence (age: 27.1±2.69 years;height: 183.5±5.12 cm; body mass: 76.3±3.06 kg), 8 midfield (age: 25.8±1.64 years; height: 178.5±8.79 cm; body mass: 75±7.63 kg)and 5 attack players (age: 28.0±1.87 years; height: 181.8±4.81 cm; body mass: 73.4±3.78 kg) according to playing positions. Theplayers was applied Yo-Yo Intermittent Recovery Level-1 (Yo-Yo IR1) which was a field test and recovery times, maximal oxygenuptake values (VO2max), maximal heart rates (HRmax) and covered distances of players were measured according to playingpositions. The Kruskal Wallis-H Test was used for determination of difference between groups, the Mann Whitney U Test was usedto determine groups which were difference, the Wilcoxon Test was used to compare first and second test measure. Also, descriptivestatistic was used to determine physical characteristics of players. As result of statistical analyze ; it was observed that midfieldplayers had the highest covered distance and VO2max values at both first and second test. Also attack players had the highest HRmaxvalues at both first and second test. In terms of recovery times, attack players had the highest values at prepatory period andgoalkeepers had highest values at competition season. Also the it was observed that the significiant increase at covered distances(respectively 1650 and 1820 m., p<0.05) and VO2max (respectively 50.2 and 51.7 ml/kg/min, p<0.05) values of players and thesignificiant decrease at HRmax (respectively 188 and 184 pulse/min., p<0.05) and recovery times (respectively 3.98 and 3.50 min.,p<0.05) values of players between first and second test. As conclusion, the significant differences were found statistically betweenrecovery time values and aerobic capacity values of elite soccer players which were obtained from tests which were carried out indifferent periods according to playing positions.
