AB  - Aim: This study aimed to investigate the effects of ischemic preconditioning (IPC) on triathlon performance in athletes.Method: Twenty-four triathletes (8 female, 16 males; mean age: 35.43±1.84 years), with at least 3 years of training and competition experience, participated. Heart rate (HR), blood pressure, rate of perceived exertion (RPE), respiratory frequency, and heart rate variability (HRV) parameters (SDNN, NN50, PNN50, RMSSD, VLF, LF, HF, LF/HF) were measured following rest, sham, and IPC conditions. IPC was applied both acutely (single session) and chronically (7 consecutive days) using a sphygmomanometer cuff inflated to 220 mmHg for 5 minutes, followed by 5 minutes of reperfusion, repeated four times. Sham involved the same protocol with 20 mmHg pressure. Data was analyzed using t-tests.Results: Triathlon completion time significantly improved after both sham and IPC, but the improvement was greater after IPC (p

N2  - Amaç: Bu çalışmanın amacı, iskemik ön koşullamanın (IPC) triatlon performansı üzerindeki etkilerini araştırmaktır.Yöntem: En az 3 yıllık antrenman ve yarışma deneyimine sahip 24 triatlet (8 kadın, 16 erkek; ort. yaş: 35,43±1,84 yıl) çalışmaya katıldı. Kalp atım hızı (KA), kan basıncı, algılanan efor derecesi (RPE), solunum frekansı ve kalp atım hızı değişkenliği (HRV) parametreleri (SDNN, NN50, PNN50, RMSSD, VLF, LF, HF, LF/HF) istirahat, sham ve IPC koşullarında ölçüldü. IPC, manşet ile 220 mmHg’ye şişirilip 5 dakika basınç uygulanması, ardından 5 dakika reperfüzyon şeklinde, 4 kez tekrar edilerek akut (tek seans) ve kronik (7 gün ardışık) olarak uygulandı. Sham koşulunda ise aynı protokol 20 mmHg basınç ile gerçekleştirildi. Veriler t-testi ile analiz edildi.Bulgular: Triatlon tamamlama süresi hem sham hem de IPC sonrasında anlamlı şekilde iyileşti, ancak IPC sonrasında bu iyileşme daha fazlaydı (p
