Sažetak
Introduction Rowing ergometers are designed to simulate movements performed during on-water rowing and are widely considered to be valuable tools for rowing training, the evaluation of rowers’ sport-specific performance, and the detection of any changes in performance capacity. The aim of this study was to predict on-water rowing performance, as measured by final rankings at the most important competition for junior rowers – the FISA World Rowing Junior Championship (WRJC), based on the 2000-m ergometer times in a sample of 398 male and female junior rowers competing in all 13 events of the 2007 WRJC. Method At the FISA WRJC (Beijing, People's Republic of China, 8-11 August 2007), a total of 398 junior rowers from 45 countries were interviewed using a questionnaire. The sample included competitors participating in 13 events held during the Championship, as well as the reserves (1.3% of the sample). Coxswains were not included. The sample represented 65.9% of all competitors, including 52.5% of the A finalists as well as 39.9% of the medalists. Following the exclusion of invalid data, the sample eventually comprised 382 junior rowers (222 males and 160 females) who entered statistical analyses. Results In all 13 events the competitors’ 2000-m ergometer times were significantly (P<0.05-0.001) correlated with their final WRJC rankings. The highest correlations were obtained for the rowers’ ergometer times in women’ s single sculls (r=0.922) followed by men’ s single sculls (r=0.804) and women’ s double sculls (r=0.793). The obtained correlations are generally higher for smaller boats [i.e. singles, doubles and pairs (r=0.638-0.922)] than for larger boats [i.e. quads, fours and eights (r=0.308-0.699)]. Simple regression analyses were used in order to define the prediction models, and the highest predictive power (R2=0.850, SEE=1.96) was obtained for women’ s single sculls. Discussion and conclusions The main findings of the present study are that the 2000-m rowing ergometer times of competitors participating in all 13 events of the 2007 WRJC are significantly (P<0.05-0.001) correlated with their final championship rankings and that improvements in their final rankings correspond to improvements in rowing ergometer times. Although the majority of obtained correlation coefficients range from medium to very high, the use of ergometer times for predictions of on-water performance is limited by the fact that on-water rowing requires specific technique compared to rowing on an ergometer (e.g. manipulation of the oar handle), the synchronization of individual motor performances in team boats, and is performed under various environmental conditions, all of which cannot be measured on an ergometer.
