The basic purpose of this study was to investigate of the relationships with sprint and jump performance of power parameters during propulsive phase of full back squat exercise and to determine which variable was associated with which loading loading. For this purpose, thirty-two men amateur athletes (age: 20.4 ± 1.98 years; height: 179.3 ± 7.23 cm; weight: 73.5 ± 9.85 kg) who actively involved in sports and have a basic level of force participated in voluntarily to this study. In the study, one repetition maximum (1RM) full back squat (SQ) strength test, vertical jump test, 5 meters and 30 meters sprint test were applied. The descriptive statistics and pearson correlation analysis was used for statistical evaluation of datas. According to statistical analysis results; It was concluded that there are mean level, negative and statistically a significant relationship between mean propulsive power (MPP) values (r = - ,607, p < 0.05) obtained at 70 % of 1RM load values and mean power (MP) values (r = - ,409; r = - ,454; p < 0.05, respectively) and peak power (PP) values (r = - ,445; r = - ,365, p < 0.05, respectively) obtained in the propulsive phase of full back squat exercise performed at 40 % and 70 % of 1RM load value with 5 meters sprint times. It was concluded that there are mean level, negative and statistically a significant relationship between PP values (r = - ,400; r = - ,355, p < 0.05, respectively) obtained at 40 % and 60 % of 1RM load values OG (r= - ,375; r = - ,394, p< 0.05) respectively) values obtained in the propulsive phase of full back squat exercise performed at 40 % and 70 % of 1RM load value with 30 meters sprint times. It was obtained that there are no statistically a significant relationship between power parameters during propulsive phases of full back squat exercise performed in different loads of 1RM and vertical jumping distance (p > 0.05).

Bu çalışmanın amacı, modern olimpiyatları organizasyonel açıdan değerlendirmek, maliaçıdan analizlerini yapmak ve tesisler bakımından değerlendirmesini yaparak ülkemizdeyapılacak bir olimpiyat için gerekli somut veriler elde etmektir. Bu bağlamda 2000 yılındanbuyana düzenlenen Yaz ve Kış Olimpiyatları çalışmaya dâhil edilmiştir. Bu olimpiyatlarınyapılabilmesi için gerekli tesisler ve finans kaynakları bakımından değerlendirilmesiyapılarak Türkiyede yapılacak bir olimpiyatın ülke ekonomisine getirileri veya götürüleriproaktif bir yaklaşımla tespit edilmeye çalışılmıştır. Çalışmanın sonucunda YazOlimpiyatlarını düzenleme maliyetlerinden çok daha az maliyetlerle Kış Olimpiyatınınyapılabileceği ve adaylık sürecinde düzenleme hakkını ülkemize verilmesinin daha kolayolabileceği sonuçlarına varılmıştır.

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.
