Hemoglobin concentration and percent reticulocytes (%retics) were analyzed in blood samples taken pre-competition, post-competition, and during out of competition testing in elite speed skaters. Percent reticulocytes during screening was not different from the values obtained post-race, and no significant gender difference was found. Mean hemoglobin concentration both in males and females was slightly higher at 1 425 m altitude compared to <750 m altitude (0.23 g/dl increase in males and 0.48 g/dl increase in females; p<0.05 and p<0.01, respectively). Mean %retics at 1 425 m altitude is higher (0.24% in males and 0.27% in females, respectively, p<0.01) compared to blood sampled <750 m altitude. The distribution of percent reticulocytes shows 11 out of 11 500 samples with %reticulocytes below 0.4%. From the 171 samples with a values >2.4% in 52 skaters at least two consecutive samples yielded a percent reticulocytes above 2.4%. In 50 individuals with generally normal values but at least in two consecutive samples values above 2.4% the pattern required additional testing. In conclusion, percent reticulocytes are a robust hematological parameter, including acute exercise.
血红蛋白浓度和网织红细胞百分比（%retic）在精英速滑运动员的竞赛前、竞赛后和竞赛外测试的血液样本中进行了分析。筛查时的网织红细胞百分比与赛后获得的值没有差异，也没有发现显著的性别差异。与<750 m 海拔相比，男性和女性的平均血红蛋白浓度在 1425 m 海拔时略高（男性增加 0.23 g/dl，女性增加 0.48 g/dl；p<0.05 和 p<0.01）。1425 m 海拔时的平均%retic 较高（男性分别为 0.24%，女性为 0.27%，p<0.01），与<750 m 海拔时采集的血液相比。网织红细胞的分布显示，在 11 名 500 名样本中，有 11 名样本的网织红细胞<0.4%。在 52 名滑冰运动员中，有 171 名样本的 a 值>2.4%，至少有两个连续样本的网织红细胞值>2.4%。在 50 名通常值正常但至少有两个连续样本值>2.4%的个体中，该模式需要进一步检测。总之，网织红细胞是一个强大的血液学参数，包括急性运动。
