The purposes of this study were to: 1) examine relationships between rowing performance and indices of metabolic parameters; 2) determine the best predictive indices of rowing performance. Ten male rowers (18.90±1.66 yrs; 186.20±6.25 cm; 79.27±7.30 kg; %body fat: 10.49±2.30%) were subjected to four sessions on a rowing ergometer. An incremental exercise test to determine the maximal oxygen uptake ( .VO2max), the corresponding maximal aerobic power (Pamax) and anaerobic threshold (AT4), a 2000 metre “all-out” test to determine the performance parameters (P2000), a five maximal strokes to determine maximal alactic anaerobic power (P5), a 40 seconds “all-out” test to determine maximal lactic anaerobic power (P40), and a 95% Pamax test until volitional exhaustion to determine maximal aerobic power were performed. In addition, competition results in 2000 metre race on single sculls were obtained. Mean .VO2max was 4.854±0.631 l·min-1 (61.61±5.59 ml·min-1 kg-1) and AT4 274.80±40.70 W, which corresponded to 74.20±4.20% of Pamax. P2000 sustained by the rowers was 358.40±51.46 W, which corresponded to 96.71±4.70% of their Pamax. While the subjects rowed at a mean overall work rate of 347.05±34.43 W during the 95% Pamax test. Mean competition time on 2000 metre distance on single sculls was 448.2±13.1 sec (7 min 28 sec), heart rate (HR) 179.94±4.92 beats·min-1 and blood lactate (LA) 16.02±2.42 mmo·l-1.
Forward stepwise multiple regression analysis produced the following model to predict 2000 metre rowing performance on single sculls when using all measured parameters of anaerobic metabolism as dependent variables: Time (sec)=518.87-0.13(P5), (R2=0.516). Using parameters of aerobic metabolism, the following model was presented: Time (sec)=512.49-0.08(AT4)-8.46 (.VO2max), (R2=0.646). In conclusion, the competition results in 2000 metre distance on single sculls are dependent on the level of anaerobic alactic power (P5), and submaximal (AT4) and maximal ( .VO2max) aerobic power.
