Abstract

Aim: This study aims to examine physiological responses during a gradually increasing running test by simultaneously evaluating heart rate (HR), heart rate variability (HRV), and muscle oxygen saturation (SmO2) parameters Materials and Methods: Sixteen male athletes aged between 18 and 27 years, with at least 3 years of sports experience, participated in the study. The average age was 19.25 ± 2.21 years, average height was 180±7.87 cm, average weight was 78.3±14.6 kg, and average body fat percentage was 11.8±5.85. HR, HRV, and SmO₂ values were recorded during the resting, running, and recovery phases throughout the test. The running protocol started at a speed of 10 km/h and increased by 1 km/h every minute until exhaustion. Recording continued for 5 minutes post-run. Results: During the gradually increasing running test, it was observed that heart rate (HR) increased while SmO₂ levels decreased. Throughout the recovery period after running, both measurement parameters tended to approach resting values Conclusion: These findings indicate that the joint assessment of HR, HRV, and SmO₂ is significant for a holistic analysis of the physiological responses to exercise. In performance evaluation, measurements such as heart rate (HR), heart rate variability (HRV), and intramuscular oxygen saturation (SmO₂) hold an important place alongside running tests.

Özet

Amaç: Bu çalışma, kalp atım hızı (HR), kalp atım hızı değişkenliği (HRV) ve kas içi oksijen saturasyonu (SmO2) parametrelerini birlikte değerlendirerek, kademeli artan koşu testi sırasında fizyolojik tepkileri incelemeyi amaçlamaktadır. Gereç ve Yöntem: Çalışmaya, 18–27 yaş aralığında, en az 3 yıllık spor geçmişine sahip, yaş ortalaması 19,3 yıl, boy ortalaması 180±7,87 cm, kilo ortalaması 78,3±14,6 kg ve vücut yağ oranı ortalaması 11,8±5,85 olan 16 erkek sporcu katılmıştır. Dinlenme, koşu ve toparlanma evrelerinde HR, HRV ve SmO₂ değerleri test süresince kaydedilmiştir. Koşu protokolü, 10 km/h hızla başlatılmış ve her dakika 1 km/h artırılarak tükenişe kadar sürdürülmüştür. Koşu sonrası 5 dakika boyunca kayıt alınmaya devam edilmiştir. Bulgular: Bulgular: Kademeli artan koşu testi sırasında HR’ın arttığı, SmO₂ seviyelerinin ise azaldığı gözlemlenmiştir. Koşu sonrası toparlanma süresince, her iki ölçüm parametresi de dinlenik değerlere yaklaşma eğilimi göstermiştir. Sonuç: Bu bulgular, HR, HRV ve SmO₂’nin birlikte değerlendirilmesinin egzersize verilen fizyolojik yanıtların bütüncül analizinde önemli olduğunu göstermektedir. Performans değerlendirmede koşu testleri ile birlikte kalp atım hızı (HR) ve değişkenliği (HRV), kas içi oksijen saturasyonu (SmO₂) gibi ölçümler önemli bir yer tutmaktadır.
