摘要
这项研究的目的是记录23天“高生活,低训练”对耐力运动员血红蛋白质量的影响。13名来自自行车、铁人三项或越野滑雪背景的男性受试者参加了这项研究。六名受试者(HIGH)每晚在模拟海拔3000米的“氮气屋”中度过8-10小时,处于常压缺氧状态,而对照组受试者在接近海平面的地方睡觉(control, n = 7)。运动员记录了他们在海拔600米进行的日常训练。在(D1或D2)和(D28) 23晚低氧暴露之前和之后测量的总血红蛋白质量(使用co -再呼吸技术测量)没有变化[HIGH 990 (127) vs 972 (97) g和CONTROL 1042 (133) vs 1033 (138) g,分别在模拟海拔暴露之前和之后]。在研究开始前(D1),在模拟海拔6 (D10)和15 (D19)晚,或离开氮室1天后(D28), HIGH组和CONTROL组进行比较时,使用自动流式细胞仪测量的网状细胞参数的实质性阵列也没有任何差异。我们得出的结论是,在模拟海拔3000米的环境中度过23个夜晚的男性耐力运动员,红细胞的生成不会受到刺激。
"Live high, train low" does not change the total haemoglobin mass of male endurance athletes sleeping at a simulated altitude of 3000 m for 23 nights.
The purpose of this study was to document the effect of 23 days of "live high, train low" on the haemoglobin mass of endurance athletes. Thirteen male subjects from either cycling, triathlon or cross-country skiing backgrounds participated in the study. Six subjects (HIGH) spent 8-10 h per night in a "nitrogen house" at a simulated altitude of 3000 m in normobaric hypoxia, whilst control subjects slept at near sea level (CONTROL, n = 7). Athletes logged their daily training sessions, which were conducted at 600 m. Total haemoglobin mass (as measured using the CO-rebreathing technique) did not change when measured before (D1 or D2) and after (D28) 23 nights of hypoxic exposure [HIGH 990 (127) vs 972 (97) g and CONTROL 1042 (133) vs 1033 (138) g, before and after simulated altitude exposure, respectively]. Nor was there any difference in the substantial array of reticulocyte parameters measured using automated flow cytometry prior to commencing the study (D1), after 6 (D10) and 15 (D19) nights of simulated altitude, or 1 day after leaving the nitrogen house (D28) when HIGH and CONTROL groups were compared. We conclude that red blood cell production is not stimulated in male endurance athletes who spend 23 nights at a simulated altitude of 3000 m.
