The anthropometric profile of rowers has been reported to be closely related to the level of sport performance. The purpose of this study was to compare the anthropometric, performance and metabolic variables between lightweight and heavyweight Greek rowers. Eighteen national level lightweight (LW; training years 6.8 ± 0.7) and 16 heavyweight (HW; training years 7.4 ± 1.4) male rowers were subjected to two exercise sessions on a rowing ergometer (Concept IIc, Nottingham, UK). An incremental exercise test was performed to determine maximal oxygen uptake (VO2max) and a 2000 meter “all-out” test to evaluate performance indices. Body fat percentage was measured by underwater weighting (Vacu·Med, Ventura, CA, USA). Anthropometric characteristics were significantly different between LW and HW rowers (Mean ± SEM) (Height 178.81 ± 1.07 vs. 186.78 ± 1.07 cm; Body Weight 72.44 ± 0.90 vs. 88.22 ± 2.2 kg; % Body fat 10.71 ± 0.32 vs. 14.6 ± 0.53%; Lean Body Mass 64.64 ± 0.96 vs. 75.29 ±1.78 kg; Fat Weight 7.79 ± 0.20 vs. 12.93 ± 0.68 kg; p<0.05, p<0.001). Metabolic characteristics were also significantly different between LW and HW rowers (VO2max 4705.09 ± 60.01 vs. 5237 ± 231.68 ml•min-1; VO2max 65.03 ± 1.03 vs. 59.37 ± 2.07 ml•kg-1min-1; VEmax 145.45 ± 5.29 vs. 165.42 ± 9.28 l•min-1; Time Trial 410.96 ± 1.70 vs. 393.05 ± 4.52 sec; Mean Power Output 323.72 ± 3.75 vs. 378.85 ± 2.79 Watt; Mean stroke rhythm 29.90 ± 0.34 vs. 28.45 ± 0.14 strokes• min-1; Maximal Blood Lactate Concentration in Incremental Test 10.35 ± 0.39 vs. 11.81 ± 0.43; Blood Lactate Concentration in 2000m, 13.64 ± 0.68 vs. 14.68 ± 0.62, p<0.05). The results assumed that the anthropometric, performance and metabolic characteristics of LW differ from those of HW rowers.
