It is unclear whether world class endurance athletes, in contrast with less well trained subjects, increase their haemoglobin mass on a regimen of living high and training low (LHTL).
To assess whether haemoglobin mass increases in world class athletes on LHTL and whether this increase is associated with peak performance at a subsequent important competition.
Two Swiss world class runners (one 5000 m and one marathon) lived for 26 days (18 hours a day) at an altitude of 2456 m and trained at 1800 m. This LHTL camp was the preparation for the World Athletic Championships taking place 27-29 days after the end of the camp. Haemoglobin mass and other haematological variables were measured before and after the LHTL camp. The performance parameter was the race times during that period.
Haemoglobin mass increased by 3.9% and 7.6%, and erythrocyte volume by 5.8% and 6.3%. The race times, as well as the ranking at the World Championships, indicated clearly improved performance after the LHTL camp.
The results suggest that LHTL with an adequate dose of hypoxia can increase haemoglobin mass even in world class athletes, which may translate into improved performance at important competitions at sea level.
与训练水平较低的受试者相比，世界级耐力运动员采用高住低训（LHTL）方案时血红蛋白含量是否会增加尚不清楚。
评估世界级运动员采用高住低训方案时血红蛋白含量是否增加，以及这种增加是否与随后重要比赛中的最佳成绩相关。
两名瑞士世界级跑步运动员（一名5000米跑运动员和一名马拉松运动员）在海拔2456米处生活26天（每天18小时），并在海拔1800米处训练。这个高住低训训练营是为训练营结束27 - 29天后举行的世界田径锦标赛做准备。在高住低训训练营前后测量血红蛋白含量和其他血液学变量。表现参数是那段时间的比赛成绩。
血红蛋白含量分别增加了3.9%和7.6%，红细胞体积分别增加了5.8%和6.3%。比赛成绩以及在世界锦标赛上的排名表明，高住低训训练营后成绩明显提高。
结果表明，即使是世界级运动员，采用适当剂量低氧的高住低训方案也能增加血红蛋白含量，这可能转化为在海平面重要比赛中的成绩提高。
