Kürek sporu rüzgar, yağmur ve soğuk gibi çevresel faktörlerden etkilenen bir spor branşı olmasından dolayı kürek ergometresi ile yapılan simule antrenmanların iç ve dış yüklerinin takibi önem kazanmaktadır. Bu araştırmanın amacı kürekçilerde 2000m ergometre ve gerçek su performanslarının iç ve dış yüklerinin karşılaştırılmasıdır. Bu çalışmaya 12 erkek kürekçi gönüllü olarak katılmıştır. Sporcuların 2000m ergometre ve suda kürek performansları 48 saat arayla 2 test gününde ölçüldü. Sporcuların test süresi (dk), kan laktat birikimi (mmoL-1), algılanan zorluk derecesi (sAZD), maksimum kalp atış hızı yüzdesi (%KAHmaks) ve ortalama kalp atış hızı (ortalama KAH/dk) her iki deneme gününde de ayrı ayrı kaydedildi. Verilerin normallik sınaması için Shapiro-Wilks testi, normal dağılım göstermeyen verilerin karşılaştırılmasında ise Wilcoxon Signed-Rank testi kullanıldı. Kürekçilerin 2000m ergometre ve gerçek su performansları karşılaştırıldığında; bitirme süresi (χ2=-3.059; p=.002), laktat birikim miktarı (χ2=-3.077; p=.002), algılanan zorluk derecesi (χ2=-3.059; p=.002), maksimum kalp atım yüzdesi (χ2=-3.061; p=.002) ve ortalama kalp atım hızı (χ2=-3.084; p=.002) değişkenleri arasında istatistiksel açıdan anlamlı farklılık olduğu tespit edilmiştir. Sonuç olarak, 2000m gerçek su performansının kürek ergometresi performansına oranla daha yüksek iç ve dış yük değerlerine sahip olduğu görülmektedir. Dolayısıyla antrenör ve sporculara kürek ergometresindeki simule antrenman yüklerini gerçek su performansına eşdeğer yüklere göre düzenlemeleri önerilmektedir.

COMPARISON OF INTERNAL AND EXTERNAL LOADS OF 2000m ROWING ERGOMETER AND ACTUAL WATER PERFORMANCES IN ROWERS

Öz

Since rowing is a sports branch affected by environmental factors such as wind, rain, and cold, it becomes important to monitor the internal and external loads of simulated training made with rowing ergometers. This research aims to compare the internal and external loads of the 2000m ergometer and actual water performances in rowers. 12 male rowers voluntarily participated in this study. The 2000m ergometer and on-water rowing performances of the athletes were measured on 2 test days with an interval of 48 hours. Test duration (min), blood lactate accumulation (mmol/L-1), rating of perceived exertion (sRPE), percentage of maximum heart rate (%HRmax) and mean heart rate (meanHR/min) of the athletes were recorded on both trial days, seperately. The Shapiro-Wilks test was used to test the normality of the data, and the Wilcoxon Signed-Rank test was used to compare the data that did not show normal distribution. Comparing the 2000m ergometer and actual water performances of rowers, the finishing time (χ2 =-3.059; p = .002) lactate accumulation level (χ2 =-3.077; p = .002), rating of perceived exertion (χ2 =-3.059; p =. 002), the maximum percentage of heart rate (χ2=-3.061; p = .002), and the mean heart rate (χ2 =-3.084; p = .002) were found to be statistically significant. As a result, it is seen that the actual water performance of 2000m has higher internal and external load values compared to the rowing ergometer performance. Therefore, it is recommended that trainers and athletes adjust their simulated training loads on the rowing ergometer according to loads equivalent to actual water performance.
