Lean body weight and aerobic and anaerobic factors have long been recognized as important determinants of performance in the 2000 met:E!r (M) 1 ace distance for rowing. Current research with noninvasive techniques has important implications for training and performance but is inconclusive. The purpose of this study was to investigate the relationship between a 2000 M rowing ergometer performance test (PT) and lean body weight (LBW), velocity at heart rate deflection (Vd), and anaerobic capacity (AC) in experienced rowers. Vd was used as an estimate of aerobic function. Thirteen trained male rowers (mean age 38.5 ± 8 years) were studied. Hydrostatic weighing at residual lung volume was used to estimate LBW. Each subject performed five exercise tests on a Concept II rowing ergometer: one 2000 M PT, two sub maximal step wise progressive tests to determine Vd (s/500 M), and two maximal 40-s anaerobic tests to determine AC. Intraclass correlation coefficients for the test/retest trials of Vd and AC were R = 0.740 and R = 0.863, respectively. Stepwise multiple linear regression analysis was used to explain variance in PT. The order of entry of each independent variable (and associated multiple R2 at each step) in the analysis was (1) Vd, 0.589; (2) LBW, 0.709; (3) AC, 0.720. The regression equation was PT (s) = 375.66 + 1.093 (Vd) - 0.820 (LBW) - 0.0007 (AC); S.E.E. = 10.01. It was concluded that performance in a 2000 M rowing ergometer PT is primarily dependent on aerobic metabolism and available lean body weight with anaerobic factors contributing to a lesser degree. These results have implications for specific training and team selection.
