Objective: Athletic performance is affected by genetic and environmental factors. Bodybuilding has been increasing around the world in recent years and it is accepted that the factors affecting athletic performance are the most important influences to achieve success in bodybuilding. The aim of our study is to determine the distribution of COL1A1 rs1800012 polymorphism associated with ligament and tendon injuries due to muscle tears with weight training and to compare the results with sedentary individuals. Material and Methods: A total of 15 Turkish bodybuilders and 50 sedentary individuals as a control group participated in our study. DNA isolation from peripheral blood samples of athletes was performed using a commercial kit (Invitrogen, Van Allen Way Carlsbad, Calif., USA). Genotyping was done by real-time polymerase chain reaction. Results: GG genotype and G allele were higher in both bodybuilders and control groups. In addition, there was no statistically significant difference in terms of genotype and allelic frequency of the COL1A1 rs1800012 polymorphism between the bodybuilders and the control group. Conclusion: Our study is the first to examine the COL1A1 rs1800012 polymorphism in Turkish bodybuilders. Our results report that the TT genotype and T allele may be protective against ligament and tendon injuries, similar to the literature. We think that similar studies will guide future studies in terms of sports injuries and COL1A1 rs1800012 polymorphism.

Amaç: Atletik performans, genetik ve çevresel faktörlerden etkilenir. Vücut geliştirme, son yıllarda tüm dünyada artış göstermekte ve vücut geliştirmede başarıya ulaşmada atletik performansı etkileyen faktörlerin en önemli etkenler olduğu kabul edilmektedir. Çalışmamızın amacı, ağırlık antrenmanı ile kas yırtılmalarına bağlı bağ ve tendon yaralanmalarına ait COL1A1 rs1800012 polimorfizminin dağılımını belirlemek ve sonuçları sedanter bireyler ile karşılaştırmaktır. Gereç ve Yöntemler: Çalışmamıza kontrol grubu olarak toplam 15 Türk vücut geliştirmeci ve 50 sedanter birey katıldı. Sporcuların periferik kan örneklerinden DNA izolasyonu ticari bir kit (Invitrogen, Van Allen Way Carlsbad, Calif., ABD) kullanılarak yapıldı. Genotipleme, gerçek zamanlı polimeraz zincir reaksiyonu ile yapıldı. Bulgular: GG genotipi ve G aleli hem vücut geliştirmecilerde hem de kontrol gruplarında daha yüksekti. Ayrıca vücut geliştiriciler ile kontrol grubu arasında COL1A1 rs1800012 polimorfizminde genotip ve alelik frekans açısından istatistiksel olarak anlamlı fark yoktu. Sonuç: Çalışmamız, Türk vücut geliştirme sporcularında COL1A1 rs1800012 polimorfizmini inceleyen ilk çalışmadır. Sonuçlarımız literatüre benzer şekilde TT genotipi ve T alelinin bağ ve tendon yaralanmalarına karşı koruyucu olabileceğini bildirmektedir. Spor yaralanmaları ve COL1A1 rs1800012 polimorfizmi açısından benzer çalışmaların ileride yapılacak çalışmalara yön vereceğini düşünüyoruz.
