Bu araştırma, karnitin ve kreatin kullanımının 13-16 yaş grubu kayaklı koşu sporcularının mesafe yarışma performansına olan etkisini değerlendirmek amacıyla yapılmıştır. Çalışmaya katılan denekler 12 erkek, 6 bayan gönüllü sporcu kontrol, kreatin ve karnitin olmak üzere 6’şar kişilik üç gruba ayrılmıştır. Her üç grup yükleme yapılmadan 2 gün önce Erciyes kayak merkezinde 5 km Klasik ve 10 km Serbest Türkiye Şampiyonası yarışmalarına katılmışlardır. Yarışmanın sonrasında gruplar 2220 m yükseklikteki kayak merkezinde konaklamaya ve yarışma pistindeki kayaklı çalışmalarına ilaç yüklemesiyle beraber devam etmiştir. Karnitin grubuna 7 gün süresince günde 2 gr karnitin 3 doza bölünerek tablet şeklinde, kreatin grubuna ise yine 7 gün süreyle günde 20 gr kreatin 4 doza bölünerek, meyve suyu ile karıştırılarak verilmiştir. Kontrol grubu herhangi bir uygulama yapılmadan diğer gruplarla birlikte kayaklı çalışmalara katılmıştır. 7 günlük yüklemeden 1 gün sonrasında gruplar yaklaşık aynı hava ve kar koşullarında tekrar aynı pistte 5 km klasik ve 10 km serbest kulüpler arası Türkiye Şampiyonası yarışmalarına katılmışlardır. Araştırmada elde edilen bulgular, SPSS paket istatistik programıyla, bağımlı gruplarda 3x2 tekrarlı ölçümlerde varyans analizi Repeated Measure Analysis of Variance ile hesaplanmıştır. Sonuç olarak 10 km serbest yarışmalarında kontrol grubu % 9,9, karnitin grubu % 10,5 , kreatin grubu ise % 12,9 gelişim gösterirken 5 km klasik yarışmalarında ise kontrol grubu %14,37, karnitin grubu %12,31 ve kreatin grubuda %10,55 gelişim göstermiş, ancak ilaca bağlı olarak gruplar arasında anlamlı bir farklılık tespit edilememiştir

THE EFFECT OF CREATIN AND CARNITINE SUPPLEMENTATION ON 5 KM CLASSIC AND 10 KM FREE STYLES RACE PERFORMANCE OF CROSS COUNTRY SKIERS.

Öz

This İnvestigation examined the effect of creatin and carnitine supplementation on 5 km classic and 10 km free styles race performance of competitive cross country skiers. Eighteen highly trained 12 male and 6 female cross country skiers aged 13-16 years seperated into 3 equal groups. All groups participated in the 5 km classic and 10 km free races styles in Erciyes at 2200m altitude ski center before the carnitine and creatine loading. After the race subjects were seperated into carnitine, creatine and control groups. Creatine supplementation was given with the dosege of 20gr divided 4 times per day and carnite was gicen with the dossage of 2gr divided 3 times per day, for seven days. After the last race all results were analysed by repeated measure analysis of variance and SPSS statistical program. According to the study there were no significant effects of carnitin and creatin supplement on 5 km classic and 10 km free styles race performans as in groups. The increased performances which were reperted can be explained by 9 days aerobic, on competition course.
