Okçuluk sporcularında plazma atriyal natriüretik peptid düzeyinin postüre bağlı değişimi

Amaç: Bu çalışmanın amacı, okçuluk sporu yapan genç erkek sporcuların plazma atriyal natriüretik peptid (ANP) düzeylerinde oturur ve yatar durumdaki değişimi ve kardiyak fonksiyonlarını incelemektir. Gereçler ve Yöntemler: Çalışmaya, gönüllü 6 okçuluk sporcusu ve 10 sedanter erkek katıldı. Katılımcılardan 10 dk'lık oturma sonrası ve 10 dk'lık yatar durumdan sonra venöz kan alındı. Plazma ANP düzeyleri ELISA yöntemi ile ölçüldü. Kardiyak parametreler ekokardiyografi ile belirlendi. Bulgular: Okçuluk sporcularının oturur durumdaki plazma ANP düzeylerinin (72.12±14.01 pg/ml) sedanter grubun oturur durumdaki ANP düzeylerinden (36.22±14.51 pg/ml) yüksek olduğu bulundu (p

The alteration of plasma atrial natriuretic peptide levels induced by postural changes in archery athletes

Objectives: The aim of this study was to investigate plasma atrial natriuretic peptid levels in sitting and supine positions and cardiac functions in young male archery athletes. Materials and Methods: Six archery athletes and 10 sedentary males volunteered to participate in the study. Venous blood samples were taken after 10 minutes sitting and after 10 minutes in supine position. Plasma ANP levels were measured by the ELISA method. Cardiac parameters were assessed by echocardiography. Results: Plasma ANP levels in sitting position were higher in archery athletes (72.12±14.01 pg/ ml) than sedentaries (36.22±14.51 pg/ml; p<0.01). Similarly, plasma ANP levels in supine position (124.41±14.66 pg/ml) were significantly higher in the athletes than sedentaries (36.95±9.83 pg/ml). Plasma ANP levels were higher in supine position than those in sitting position in archery athletes (p<0.01). No significant increase in plasma ANP levels were found in supine position than sitting position in sedentary group. Echocardiographic parameters were similar in athletes and sedentary subjects. Conclusion: It is concluded that regular archery exercises without prominent functional and morphological alterations in the heart may cause differences in plasma ANP levels. Marked posture-related alterations may occur in plasma ANP levels of trained archery athletes.
