Okçuluk Sporcularında Plazma Atriyal Natriüretik Peptid Düzeyinin Postüre Bağlı Değişimi

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 10sedentary males volunteered to participate in the study.Venous blood samples were taken after 10 minutessitting and after 10 minutes in supine position. PlasmaANP levels were measured by the ELISA method.Cardiac parameters were assessed by echocardiog-raphy. Results: Plasma ANP levels in sitting positionwere 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 inthe athletes than sedentaries (36.95±9.83 pg/ml).Plasma ANP levels were higher in supine positionthan those in sitting position in archery athletes(p 0.01). No significant increase in plasma ANPlevels were found in supine position than sittingposition in sedentary group. Echocardiographicparameters were similar in athletes and sedentarysubjects. Conclusion: It is concluded that regular archery exercises without prominent functional and mor-phological alterations in the heart may cause differ-ences in plasma ANP levels. Marked posture-related alterations may occur in plasma ANP levels of trained archery athletes.
