Maximal exercise variables during the non-invasive experiment.

Values are means±SE (n = 7). a reflects arterialized samples from capillary blood; v reflects arm venous samples. RER, respiratory exchange ratio. The subjects were evaluated before (PRE) and after a 5-week treatment with recombinant human Epo (POST), in normoxia and in acute normobaric hypoxia equivalent to altitudes ranging from 1500 m to 4500 m. *P<0.05 POST vs PRE. §P<0.05 hypoxia vs normoxia.

数据以平均值±标准误（Standard Error, SE）表示（n=7）。a代表动脉化毛细血管血样本；v代表手臂静脉血样本。呼吸交换比（respiratory exchange ratio, RER）。本研究在常氧（normoxia）及相当于海拔1500米至4500米的急性常压低氧（normobaric hypoxia）条件下，对受试者于重组人促红细胞生成素（recombinant human Epo）5周治疗前（PRE）及治疗后（POST）分别进行评估。*P<0.05 表示POST组与PRE组比较差异具有统计学意义；§P<0.05 表示低氧组与常氧组比较差异具有统计学意义。
