Haemoglobin mass (Hb mass), maximum oxygen consumption (VO2max), simulated 4000 m individual pursuit cycling performance (IP4000), and haematological markers of red blood cell (RBC) turnover were measured in 8 male cyclists before and after (A) 31 d of altitude training at 2690 m. The dependent variables were measured serially after altitude on d A3-4, A8-9 and A20-21. There was no significant change in Hb mass over the course of the study and VO2max at d A9 was significantly lower than the baseline value (79.3 +/- 0.7 versus 81.4 +/- 0.6 ml x kg(-1) x min(-1), respectively). No increase in Hb mass or VO2max was probably due to initial values being close to the natural physiological limit with little scope for further change. When the IP4000 was analysed as a function of the best score on any of the three test days after altitude training there was a 4% improvement that was not reflected in a corresponding change in VO2max or Hb mass. RBC creatine concentration was significantly reduced after altitude training, suggesting a decrease in the average age of the RBC population. However, measurement of reticulocyte number and serum concentrations of erythropoietin, haptoglobin and bilirubin before and after altitude provided no evidence of increased RBC turnover. The data suggest that for these elite cyclists any benefit of altitude training was not from changes in VO2max or Hb mass, although this does not exclude the possibility of improved anaerobic capacity.
在8名男性自行车运动员进行2690米高度的31天高原训练前后，测量了血红蛋白量（Hb质量）、最大摄氧量（VO2max）、模拟4000米个人追逐赛自行车成绩（IP4000）以及红细胞（RBC）更新的血液学指标。在高原训练后的第A3 - 4天、A8 - 9天和A20 - 21天连续测量因变量。在研究过程中，Hb质量没有显著变化，并且在第A9天的VO2max显著低于基线值（分别为79.3±0.7与81.4±0.6毫升·千克⁻¹·分钟⁻¹）。Hb质量和VO2max没有增加可能是由于初始值接近自然生理极限，几乎没有进一步变化的空间。当将IP4000作为高原训练后三个测试日中任何一天的最佳成绩的函数进行分析时，有4%的提高，但这并未反映在VO2max或Hb质量的相应变化中。高原训练后RBC肌酸浓度显著降低，表明RBC群体的平均年龄下降。然而，在高原训练前后测量网织红细胞数量以及促红细胞生成素、触珠蛋白和胆红素的血清浓度，没有提供RBC更新增加的证据。数据表明，对于这些精英自行车运动员来说，高原训练的任何益处并非来自VO2max或Hb质量的变化，尽管这并不排除无氧能力提高的可能性。
