The Effects of Stretching Training on Erythrocyte Rheological Properties and Anaerobic Performance in Healthy Young Males

Amaç: Germe egzersizi, fleksibilite ve performansı geliştirmek için kullanılmaktadır. Bu çalışmada, germe egzersizinin eritrosit deformabilite ve agregasyonu, fleksibilite ve performans üzerindeki kısa ve uzun süreli etkilerinin incelenmesi amaçlanmıştır. Gereç ve yöntem: Çalışmaya ortalama yaşları 20.71±0.52 yıl olan 7 genç, erkek denek katılmıştır. Germe protokolü 60 saniyelik, 3 tekrarlı, haftada 3 gün olmak üzere 6 hafta uygulanmıştır. Kan örnekleri ilk egzersizden önce, hemen sonra ve 6. haftanın sonunda egzersiz bitiminde alınmıştır. Deneklere ters yönde çömelme ve sıçrama ile esneklik ölçümleri ve sprint testleri uygulanmıştır. Hemoreolojik parametreler ektasitometre aracılığıyla ölçülmüştür.Bulgular: Deneklerin esneklik ölçümlerinde istatistiksel olarak önemli bir yükselme, sprint zamanında ise azalma gözlenmiştir. İlk gün egzersiz sonrası eritrosit deformabilitesinde istatistiksel olarak önemli olmayan akut bir artış gözlenmiştir. 6. hafta sonunda son egzersizi takiben ise eritrosit deformabilitesinde hafif bir düşüş tespit edilmiştir. Eritrosit agregasyonu ilk egzersiz sonrası istatistiksel olarak anlamlı düzeyde azalmış, 6. haftada egzersiz sonrası ise artmıştır. Sonuç: Çalışmamızın sonuçları, sporcuların fiziksel kapasitelerini geliştirmek için uygulanan germe egzersiz eğitiminin, kan akımının düzenlenmesine ve eritrosit deformabilitesinde akut artışlar, agregasyonunda ise azalmalar sağlayarak bireylerin atletik performansına katkıda bulunduğunu göstermektedir

Genç sağlıklı erkeklerde esneklik antrenmanının eritrosit reolojik özelliklerine ve anaerobik performansa etkileri

Purpose: Stretching exercise training is used to improve flexibility and performance. This study aimed to investigate the short and long-term effects of stretching exercise on flexibility, performance, red blood cell (RBC) deformability and aggregation. Materials and methods: 7 young male subjects (mean age 20.71±0.52 years) participated in the study. Stretching protocol consisted of 3 repetitions for 60 seconds, 3 days/week, applied for 6 weeks. Blood samples were obtained before and immediately after the first stretching exercise and on the last day of the program. Flexibility measurement was performed, as well as counter movement, squat jump, sprint tests. Hemorheological parameters were determined using an ektacytometer.Results: A significant elevation in flexibility and decrement in sprint time were observed. Following an acute insignificant elevation immediately after the exercise on the first day, RBC deformability was slightly decreased on the last day after the exercise. RBC aggregation significantly decreased immediately after the stretching exercise on the first day, while post-exercise elevation was detected on the 6th week. Conclusion: The results of the current study indicate that the stretching exercise training used to develop physical capacity of the athletes contributes to blood flow and thus, athletic performance of the individual by inducing acute increments in RBC deformability and through decrements in erythrocyte aggregation
