Duplicate haemoglobin mass (Hb) measurements are recommended before and after altitude training sojourns to identify individual adaptations in athletes with a high level of certainty. Duplicate measurements reduce typical error (TE) and disclose measurement outliers, but are usually made on separate days, which is not a practical protocol for routine services in elite sport settings. The aim of this study was therefore to investigate whether it is safe (carboxyhaemoglobin<10%) to measure Hb twice on the same day and to compare TE with measurements made on separate days. 18 healthy men completed 3 different procedures to measure Hb twice a day with the carbon monoxide rebreathing method: A (Hb measured twice within 6 h), B (dito A, combined with 1 h of hyperoxic training between the tests), C (dito B, within 2 h). First Hb measurements of the 3 test days served as procedure D. Carboxyhaemoglobin did not exceed 10% in any procedure. TE and confidence limits for procedures A, B, C and D were 1.4% (1.0-2.1%), 1.1% (0.8-1.7%), 1.3% (1.0-2.0%) and 1.5% (1.2-2.1%), respectively. Duplicate measurements of Hb on the same day are feasible and show TE similar to triplicate measurements on separate days.
建议在高原训练前后进行重复血红蛋白（Hb）测量，以高度确定地识别运动员的个体适应性变化。重复测量可减少典型误差（TE）并发现测量异常值，但通常在不同日期进行，这对于精英运动环境中的常规服务来说并非实用方案。因此，本研究的目的是调查同一天测量两次Hb是否安全（羧基血红蛋白<10%），并将TE与在不同日期进行的测量结果进行比较。18名健康男性采用一氧化碳再呼吸法完成了3种不同的程序，每天测量两次Hb：A（6小时内测量两次Hb）、B（同A，两次测试之间进行1小时高氧训练）、C（同B，在2小时内）。3个测试日的首次Hb测量作为程序D。在任何程序中，羧基血红蛋白均未超过10%。程序A、B、C和D的TE及置信限分别为1.4%（1.0 - 2.1%）、1.1%（0.8 - 1.7%）、1.3%（1.0 - 2.0%）和1.5%（1.2 - 2.1%）。同一天重复测量Hb是可行的，且显示出与在不同日期进行的三次测量相似的TE。
