Abstract (2. Language): 
The purpose of this study was to investigate the effects of creatine supplementation on sprint performance in high intensity intermittent running. Twenty male soccer players aged 19.17 ± 1.38 participated in this study. 3 running tests were performed for each subject in different days. In test A maximum speed was assessed. Subjects began to run with a speed of 8 km/hr and speed was increased 1 km/hr in every one minute until exhaustion. Maximum running speeds were recorded. In test B each subject ran seven times thirty meter sprint with 1 minute passive resting periods between runs. In test C each subject ran seven times thirty meter sprint with 1 minute intervals completed a running speed at 70% of individual maximum velocity (R70). Running times were recorded during the both B and C tests. Then 4-day period of 0.3 gr/kg body weight creatine or plasebo (lactose) supplementation was given to the subjects. Second and third day after the creatine or plasebo supplementation B and C sprint tests were repeated. The significance of the differences were analysed using paired t test. A significant increase in body weight was found after the creatine supplementation period (pxO.001). Running times were significantly lower in B and C sprint tests after the supplementation (p<0.05). The findings of this investigation suggest that creatine supplementation improved sprint performance in high intensity intermittent running between resting and also submaximal exercise periods.

Bu çalışma kreatin yüklemenin, yüksek şiddetli, aralı egzersizlerde, sprint performansı üzerine etkisini incelemek amacıyla planlanmıştır Çalışmaya yaş ortalaması 19.17 ± 1.38 olan 20 erkek futbol oyuncusu katılmıştır Deneklere farklı günlerde 3 kez koşu testi yaptırılmıştır. A koşusunda maksimum hız tespit edilmiştir Deneklerden 8 km/s başlangıç hızı ve her bir dakikada 1 km/s hız artışı ile yo-ruluncaya kadar koşmaları istenmiştir. Deneklerin ulaştıkları koşu hızı maksimum koşu hızı olarak kaydedilmiştir. B koşusunda denekler 7 kez 30 metre sprint koşusu yapmışlar ve koşular arasında birer dakika pasif olarak dinlenmişlerdir. C koşusunda ise denekler 7 kez 30 metre koşmuşlar ve koşular arasında daha önce tespit edilen maksimum hızın % 701 şiddetinde 1 dakika süreyle koşmuşlardır B ve C koşularında koşu süreleri kaydedilmiştir. Daha sonra 4 gün süre ile kilogram başına 0,3 gr. dozla kreatin yada plasebo yüklemesi yapılmıştır Yüklemenin bitiminden sonraki 2. ve 3. gün B ve C sprint koşuları tekrarlanmıştır Elde edilen verilerin istatistiksel analizi iki eş arasındaki farkın önemlilik testi ile yapılmıştır. Deneklerin vücut ağırlıklarında kreatin yüklenmesi sonrası, kreatin öncesine oranla belirgin bir artış saptanmıştır (p<0.001). B ve C koşularında kreatin yüklemesi sonrası koşu sürelerinde istatistiksel olarak anlamlı azalma saptanmıştır (p<0.05). Bu bulgular kreatinin sprint, aralarında hem pasif dinlenimli, hem de submaksimal koşunun olduğu birden fazla koşuda koşu performansını olumlu olarak etkilediğini göstermektedir.
