Özet
Adölesan erkek yüzücülerde pancar suyunun anaerobik yüzme performansı, kan laktat düzeyi ve yorgunluk üzerine etkisini belirlemek amacıyla tek kör müdahale araştırması olarak planlanan bu araştırmayı Bursa ilinde spor kulüplerinde lisanslı 14 adölesan erkek yüzücü oluşturmaktadır. Yüzücüler sosyodemografik bilgileri, beslenme alışkanlıklarının değerlendirildiği ilk görüşmede 24 saatlik besin tüketim kayıtları sorgulanmış ve antropometrik ölçümleri kaydedilmiştir. Yüzücülere, çalışmanın ilk haftası herhangi bir içecek tüketmeden 8x100 metrelik maksimum eforlu yüzme performansı uygulandı. Çalışmanın ikinci haftasında her antrenmandan 2,5 saat önce (üç gün 2 x250 mL ve 3 gün 1 x250 mL) 0,6 mmol/250 mL NO3- içeren plasebo içecek tüketti. Çalışmanın son haftasında önceki hafta ile benzer şekilde fakat bu sefer 8 mmol/250 mL NO3- içeren pancar suyu tüketildi. Çalışmada her performans testi sonrası kan laktat ölçümü ve algılanan yorgunluk düzeyi kaydedildi. Egzersiz öncesi akut alınan pancar suyunun yüzmede performans süreleri üzerine etkisine bakıldığında 8x100 metre performansının genel derecelerinde son hafta olan süreleri ilk iki haftaya göre daha hızlı olsa da istatistiksel olarak anlamlı bir fark olmadığı fakat üçüncü 100 metre performans sürelerinde birinci ve üçüncü hafta arasında istatistiksel olarak anlamlı bir düşüş gözlemlenmiştir (p<0.05). Çalışmamızda müdahale öncesi performans testi sonrasında kan laktat ortalaması 15,09±3,30 mmol/l, plasebo içecek sonrası 16,23±4,30 mmol/l ve pancar suyu alımı sonrası 15,21±4,01mmol/l saptamıştır (p<0.05). Müdahale öncesi, plesabo içecek ve pancar suyu tüketimi sonrası yüzücülerde algılanan yorgunluğun azaldığı tespit edilmiştir (p:0.019; p<0.05). Adolesan erkek yüzücülerde altı gün boyunca pancar suyu alımının performans sürelerinde ve kan laktat düzeyinde önemli bir iyileşme olmadığı fakat algılanan yorgunluk düzeyinde azalma neden olduğu görülmüştür.
This study, planned as a single-blind intervention study to determine the effects of beetroot juice on anaerobic swimming performance, blood lactate level and fatigue in adolescent male swimmers, consists of 14 licensed adolescent male swimmers working in sports clubs in Bursa province. In the first interview where the sociodemographic information and nutritional habits of the swimmers were evaluated, 24-hour food consumption records were questioned and anthropometric measurements were recorded. The swimmers underwent a maximum effort swimming performance of 8x100 meters without consuming any beverages in the first week of the study. In the second week of the study, they consumed a placebo beverage containing 0.6 mmol/250 mL NO3- 2.5 hours before each training (2 x250 mL for 3 days and 1 x250 mL for 3 days). In the last week of the study, similar to the previous week, but this time containing 8 mmol/250 mL NO3-, beetroot juice was consumed. After each performance test in the study, blood lactate measurements and perceived fatigue levels were recorded. When the effect of acutely taken beetroot juice before exercise on performance times in swimming was examined, it was observed that although the times in the last week were faster than the first two weeks in the general degrees of 8x100 meter performance, there was no statistically significant difference, but a statistically significant decrease was observed in the third 100 meter performance times between the first and third weeks (p<0.05). In our study, after the performance test before the intervention, the mean blood lactate was 15.09±3.30 mmol/l, 16.23±4.30 mmol/l after placebo drink and 15.21±4.01 mmol/l after beetroot juice intake (p<0.05). It was determined that perceived fatigue decreased in swimmers after placebo drink and beetroot juice consumption before the intervention (p:0.019; p<0.05). It was observed that beetroot juice intake for six days in adolescent male swimmers did not cause a significant improvement in performance times and blood lactate levels, but it caused a decrease in the perceived fatigue level.
