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

Abstract

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 (X?Age: 18 ± 1.48 yıl; X?Height: 179 ± 6.67 cm; X?Body weight: 71 ± 6.4 kg) 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. 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 (?2 =-3.059; p = .002) lactate accumulation level (?2 =-3.077; p = .002), rating of perceived exertion (?2 =-3.059; p =. 002), the maximum percentage of heart rate (?2=-3.061; p = .002), and the mean heart rate (?2 =-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. © 2021, Ataturk Universitesi.
