Elite rowers are highly endurance trained and present with a large lean body mass (LBM), which is closely related to total haemoglobin mass (tHbmass), a major determinant of blood O2-transport. This study aims to determine the magnitude of tHbmass in elite rowers and its relation to performance parameters that are common in rowing worldwide. 13 rowers (3 lightweight) performed a 2000 m test to evaluate maximal performance on the rowing ergometer (P2k) and an incremental test to evaluate power output at lactate 2 and 4 mmol/l (N=15). tHbmass was measured by CO-rebreathing. tHbmass amounted to 1285±123 g (open weight) and 1059±48 g (lightweight). Coefficients of correlation between tHbmass and power output increased with intensity, being highest for P2k (r=0.80). An increase of 100 g tHbmass is associated with an increase of 24 W in P2k between subjects. The ratio between tHbmass/LBM amounted to approximately 16 g/kg. Absolute tHbmass in elite rowers of open weight class is very high. In relation to body mass or LBM, data is similar to other endurance athletes. The relation between P2k performance and tHbmass is very large. However, it is partly mediated by body composition.
精英赛艇运动员接受了高强度的耐力训练，拥有较大的瘦体重（LBM），这与总血红蛋白量（tHbmass）密切相关，而总血红蛋白量是血液氧气运输的主要决定因素。本研究旨在确定精英赛艇运动员的总血红蛋白量的大小及其与全球赛艇运动中常见的性能参数之间的关系。13名赛艇运动员（3名轻量级）进行了2000米测试，以评估赛艇测功仪上的最大性能（P2k），并进行了递增测试，以评估乳酸浓度为2和4毫摩尔/升时的功率输出（N = 15）。通过一氧化碳再呼吸法测量总血红蛋白量。总血红蛋白量在无体重限制组为1285±123克，在轻量级组为1059±48克。总血红蛋白量与功率输出之间的相关系数随强度增加而增加，在P2k时最高（r = 0.80）。受试者之间，总血红蛋白量每增加100克，P2k功率增加24瓦。总血红蛋白量与瘦体重的比率约为16克/千克。无体重限制组精英赛艇运动员的绝对总血红蛋白量非常高。与体重或瘦体重相关的数据与其他耐力运动员相似。P2k性能与总血红蛋白量之间的关系非常大。然而，这部分是由身体成分介导的。
