Abstract：
:The aim of this study was to examine the effects of a carbohydrate-electrolyte drink on specific soccer tests and performance. Twenty-two professional male soccer players volunteered to participate in the study. The players were allocated to two assigned trials ingesting carbohydrate-electrolyte drink (7% carbohydrates, sodium 24 mmol.l-1, chloride 12 mmol.l-1, potassium 3 mmol.l-1) or placebo during a 90 min on-field soccer match. The trials were matched for subjects' age, weight, height and maximal oxygen uptake. Immediately after the match, players completed four soccer-specific skill tests. Blood glucose concentration [mean (SD)] was higher at the end of the match-play in the carbohydrate-electrolyte trial than in the placebo trial (4.4 (0.3) vs. 4.0 (0.3) mmol.l-1, P < 0.05). Subjects in the carbohydrate-electrolyte trial finished the specific dribble test faster in comparison with subjects in the placebo trial (12.9 (0.4) vs. 13.6 (0.5) s, P < 0.05). Ratings of the precision test were higher in the carbohydrate-electrolyte trial as compared to the placebo trial (17.2 (4.8) vs. 15.1 (5.2), P < 0.05) but there were no differences in coordination test and power test results between trials. The main finding of the present study indicates that supplementation with carbohydrate-electrolyte solution improved soccer-specific skill performance and recovery after an on-field soccer match compared with ingestion of placebo. This suggests that soccer players should consume carbohydrate-electrolyte fluid throughout a game to help prevent deterioration in specific skill performance. :Bu çalışmanın amacı karbonhidrat-elektrolit bir içeceğin futbola özgü testler ve başarı üzerine olan etilerini incelemekti. 22 profosyonel erkek futbolcu çalışmaya katılmak için gönüllü oldu. Oyuncular 90 dak’lık futbol maçı sırasında karbonhidrat-elektrolit (%7 karbonhidrat, 24 mmol.l-1 sodyum, 12 mmol.l-1 klor, 3 mmol.l-1 potasyum) veya plasebo içen olmak üzere iki gruba ayrıldı. Gruplar yaş, vücut ağırlığı, boy ve maksimal oksijen alımı olarak benzerdi. Maçı takiben oyuncular futbola özgü 4 yetenek testini tamamladı. Maçın sonunda kan glikoz konsantrasyonu (a.o.±SS) karbonhidrat-elektrolit grubunda plasebo grubundan daha yüksekti (4.4±0.3 karşı 4.0±0.3 mmol.l-1, P < 0.05). Karbonhidrat-elektrolit grubundaki denekler plasebo grubundaki denekler ile karşılaştırıldığında özel top sürme testini daha hızlı tamamladılar (12.9±0.4 karşı 13.6±0.5 san, P < 0.05). Doğruluk testinin oranları plasebo grubu ile karşılaştırıldığında karbonhidrat-elektrolit grubunda daha yüksekti (17.2±4.8 karşı 15.1±5.2, P < 0.05). Fakat koordinasyon testi ve güç testi sonuçları için gruplar arasında farklılıklar yoktu. Sunulan çalışmanın bulguları karbonhidrat-elektrolit solusyonu eklemenin plasebo alımı ile karşılaştırıldığında futbola özgü yetenek ve maç sonrası toparlanmaya iyileştirdiğini göstermektedir. Bu, karbonhidrat-elektrolit sıvı tüketinin maç boyunca futbola özgü yeteneklerin kötülüşmesi konusunda koruyucu katkısı olduğuna işaret etmektedir.
