Özet
Amaç: Supramaksimal egzersizden sonra aktif dinlenmenin kan laktat değerlerine etkilerini araştırmaktır. Yöntem: Çalışmaya yaşı 22.2 2.1 yıl, boyu 179.0 5.5 cm, vücut ağırlığı 69.2 5.2 kg olan 22 erkek sporcu katıldı. 5 kişide VO2max ölçüldü. Bir gün sonra bu kişilerde VO2max’ın % 35’indeki yük belirlendi ve aktif dinlenme yükü olarak kabul edildi. Bisiklet ergometresinde vücut ağırlığının kilogramı başına 95 gram yükte Wingate testi uygulandı. Wingate testinden sonra 10 dk süreyle grubun yarısına pasif dinlenme, diğer yarısına bisiklet ergometresinde VO2max’ın % 35’inde aktif dinlenme yaptırıldı. Dinlenmede, Wingate testinin bitiminde, aktif ve pasif dinlenmenin 5. ve 10. dakikalarında venöz kan örnekleri alınarak laktat düzeyleri belirlendi. 24 saat sonra tekrar Wingate testi uygulanarak daha önce aktif dinlenme yapanlar pasif, pasif dinlenme yapanlar aktif olarak dinlendirildi. Dinlenimde, test bitiminde ve dinlenmenin 10. dakikasında kalp hızı kaydedildi. Verilerin istatistiki analizinde eşleştirilmiş t testi kullanıldı. Anlamlılık düzeyi 0.05 olarak kabul edildi. Bulgular: Aktif ve pasif dinlenme öncesinde yapılan Wingate testinden elde edilen zirve güç, ortalama güç ve yorgunluk indeksi değerleri arasında fark bulunmadı. Testten önceki ve test bitimindeki kalp hızı pasif dinlenmedekilerden farklı değildi. Ancak, aktif dinlenmenin 10. dakikasında kalp hızı pasif dinlenmenin 10. dakikasından yüksekti. Aktif ve pasif dinlenme uygulamaları arasında dinlenmede, test bitiminde, 5. ve 10. dakikalarda elde edilen kan laktat düzeyleri açısından fark bulunmadı. Test sonrasından 5. dakikaya hem aktif hem de pasif dinlenmede anlamlı laktat artışı gözlenirken, 5. dakikayla 10. dakika arasında laktat düzeyinin pasif dinlenmede değişmediği, aktif dinlenmede azaldığı bulundu. Sonuç: VO2max’ın % 35’inde 10 dakika aktif dinlenmenin 5-10. dakikalar arasında kan laktatının eliminasyonunu artırdığı sonucuna varıldı. Laktat eliminasyonunu hızlandırdığı için yoğun egzersizlerden sonra pasif dinlenme yerine aktif dinlenme yapılmasının uygun olacağı düşünüldü.
Objective: It was aimed to investigate the effects of active recovery on blood lactate concentration after supramaximal exercise. Methods: Twenty-two male athletes (aged 22.2 ± 2.1 years, height 179.0 ± 5.5 cm, body weight 69.2 ± 5.2 kg) participated to the study. On five subjects VO2max were measured. After one day, the load at 35% of VO2max was determined in these subjects and was accepted as active recovery load. Wingate test performed at 95 g.kg-1 load. After Wingate test, for half of the subjects passive recovery and for the other half active recovery at 35% of VO2max were performed for ten minutes. After 24 hours, another Wingate test was performed with other recovery type. For blood lactate concentration, blood samples were taken at 5th and 10th minutes of active and passive recovery at the rest and at the end of Wingate tests. Heart rate were measured at the rest, at the end of the Wingate test and 10th minutes of both active and passive recoveries. Paired t test was used in statistical analysis of the data and statistical significance was set at level of p<0.05. Results: No significant differences among peak power, mean power and fatigue index obtained from Wingate tests done before active and passive recoveries were found. Heart rate at 10th min active recovery was higher than at 10th min of the passive recovery. No significant differences were found between level of blood lactate at the rest, at the end of the test, at 5th and 10th minutes of the active and passive recovery. The increase of lactate from the end of the rest through 5th min through 10th min were more than those of active recovery. Conclusion: It is concluded that 10-min active recovery at 35% of VO2max increased elimination of blood lactate between 5 and 10 minutes after a supramaximal exercise. For this reason, it should be preferred to use active recovery rather than passive recovery after intense exercises.
