The comparing according to playing positions of recovery times and aerobic capacity during preparatory period and competition season of elite soccer 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.
