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.
