Abstract

Recent studies have addressed the effects of the microbiota on the human body. The presence of the microbiota varies depending on the composition of bacteria colonizing the digestive system, genetic makeup, lifestyle, antibiotic use, and the presence of diseases. A person's diet is crucial for the diversity of microbiota species. Studies have shown the effects of probiotic use on the gut microbiota in athletes. Physical activity increases the number of bacteria, particularly those belonging to the Clostridiales order and the genera Lactobacillus, Prevotella, Bacteroides, and Veillonella, and these numbers vary depending on the sport. These bacteria are found in athletes participating in sports requiring high VO2 max. Athletes' nutrition also influences the composition of the microbiota. A high-fiber diet increases the amount of probiotic microorganisms such as Lactobacillus or Bifidobacterium bacteria, indicating the need to add probiotics and prebiotics to the diet. It is not possible to give a definitive answer as to how the gastrointestinal microbiota changes in athletes, and further studies and analysis are required. This study describes the relationships between physical activity, nutrition, and digestive system microbiota in athletes, and the differences in microbial composition in various sports.

Özet

Son yıllarda güncel çalışmalarda mikrobiyotanın insan vücudu üzerindeki etkilerine değinilmektedir. Mikrobiyotanın varlığı, kişinin sindirim sistemini kolonize eden bakterilerin bileşimine, genetik yapısına, yaşam tarzına, antibiyotik kullanımına ve hastalıkların varlığına bağlı olarak değişmektedir. Kişinin beslenmesi mikrobiyotanın tür çeşitliliğinde oldukça önemlidir. Çalışmalarda sporcuların probiyotik kullanımının bağırsak mikrobiyotası üzerindeki etkileri gösterilmektedir. Fiziksel aktivite, özellikle Clostridiales takımına ve Lactobacillus, Prevotella, Bacteroides ve Veillonella cinslerine ait bakterilerin sayısını artırır ve sayıları spor dalına göre değişmektedir. Bu bakteriler, yüksek VO2 max gerektiren spor branşlarındaki sporcularda bulunmaktadır. Sporcuların beslenmesi de mikrobiyotanın bileşimini etkiler. Posadan zengin bir diyet, probiyotik mikroorganizmalar olan Lactobacillus veya Bifidobacterium bakterilerinin miktarını artırır; bu da diyete probiyotik ve prebiyotik eklenmesi ihtiyacını gösterir. Sporcularda gastrointestinal sistem mikrobiyotasının nasıl değiştiğine dair kesin bir cevap vermek mümkün değildir ve daha fazla çalışma ve analiz gerektirir. Bu çalışmada sporcularda fiziksel aktivite, beslenme ve sindirim sistemi mikrobiyotası, çeşitli spor dallarındaki mikrobiyal bileşimdeki farklılıklar arasındaki ilişkiler anlatılmaktadır.
