FARKLI ORANLARDA KREATİN KULLANIMININ AMATÖR ERKEK FUTBOLCULARDA SPRINT PERFORMANSINA ETKİSİ
Bu çalışma, farklı miktarlarda akut kreatin
yüklemesinin sprint performans üzerine olan etkisini incelemek amacıyla
yapıldı. Çalışmada 18 amatör genç erkek futbolcu denek olarak kullanıldı.
Denekler üç gruba ayrılarak, beş gün süreyle 1. gruba 4 x 5 g /gün, 2. gruba
2x5 g /gün kreatin monohidrat ve plesebo grubuna 4 x 5 g /gün glikoz verildi.
Kreatin yüklenme öncesi ve sonrası vücut ağırlıkları belirlendi, aralarında 30
sn dinlenme süresi bulunan 10 x 20 m sprint zamanları ve son sprinti takiben 2
dakikalık bir dinlenmeden sonra sıçrama yükseklikleri ölçüldü. Kreatin yükleme
sonrası vücut ağırlığında anlamlı düzeyde artış (p<0.05) belirlendi Ağırlık
artışları 1. Grupta 0.96 kg, 2. grupta 0.42 kg olarak tespit edildi. Sıçrama
yüksekliğinde 2. grup ve plesebo grubunda farklılık belirlenmezken (p>0.05),
1. grupta da önemli düzeyde (p<0.05) artış saptandı. Bacak ekstansör kaslarının
performansını gösteren sıçrama yüksekliğindeki anlamlı artışın, kreatin yükleme
ile artan quadriceps kreatin ve fosfolcreatin içeriğine bağlanabilir. Plesebo
grubu ve 2. gurupta 10 tekrarlı 20 m sprint zamanlan değişmezken, 1. grup Tın
8, 9 ve 10. tekrarlardaki ortalama sprint zamanı ile toplamdaki ortalama sprint
zamanları kısalmış anlamlı düzeyde düşmüştür.
Sonuç olarak, 5 gün süresince 20 g /gün akut kreatin
yüklemesi yapılan amatör genç futbolcularda, bir maçta sonucu etkilediği
bilinen, kısa süreli yüksek şiddetli eforlarda (örn.; sprint sıçrama) gözlenen
iyileşmenin futbol performansını olumlu yönde etkilediği ve futbolcuların
ergojenik yardımcı olarak kreatin monohidrat kullanmasının uygun olabileceği
belirlendi. Ayrıca bu çalışma, aynı süre içerisinde yapılan 10 g/gün akut
kreatin yüklemesinin bir ergojenik etki oluşturmadığını ortaya koymuştur.

THE EFFECT OF SPRINT PERFORMANCE OF AMATEUR MALE SOCCER USING DIFFERENT RATIO CREATINE
This study was carried out to investigate the effect
of creatine loading of various amounts on the performance. In the study, 18
young amateur male soccerer were used as subjects. The subjects were divided
into three groups, and creatine monohydrate was given as 4x5 g/day (Group I),
2x5 g/day (Group II), and dextrose was given 4x5 g/day to the placebo group.
Body weights before and after creatine loading were measured and 10x20 m sprint
demation, having 30 second- resting time, and leaping heights after 2 second-resting
following sprint were measured. Body weight increased after creatine loading
signifıcantly in the first group. The increase was 0.96 in the fırst group
whereas 0.42 kg in the second group. While the height of jump didn’t change in
placebo or the second group, the increase was statistically signifıcant in the
first group. The significant increase of jump height indicating the performance
of leg extansor muscules may be due to increased phospocreatine content of
quadricebs with loading. While 10- repeated 20 m-sprint times don’t change in
placebo and the second groups, total average sprint time and average sprint
time’s in 8’th,9’th,10’th repetitions in the fırst group lowered signifıcantly. In
conclusion. Acute creatine loading (20 g/day for 5 days)improved the sprint
jumping perfprmance in amateur young male soccerers. This improvement may
affect the result of a match faveurably in soccer. Therefore, the use of
creatine as ergogenic contributor could be suitable. In addition this study
revealed that 10 g/day acute creatine loading done on the same day didn’t have
any ergogenic effect.
