Abstract

Live High: Train Low (LHTL) altitude training is a popular ergogenic aid amongst athletes. An alternative hypoxia protocol, acute (60-90 min daily) Intermittent Hypoxic Exposure (IHE), has shown potential for improving athletic performance. The aim of this study was to compare directly the effects of LHTL and IHE on the running and blood characteristics of elite triathletes. Changes in total haemoglobin mass (Hb(mass)), maximal oxygen consumption (VO2max), velocity at VO2max (vVO(2max)), time to exhaustion (TTE), running economy, maximal blood lactate concentration ([La]) and 3 mM [La] running speed were compared following 17 days of LHTL (240 h of hypoxia), IHE (10.2 h of hypoxia) or Placebo treatment in 24 Australian National Team triathletes (7 female, 17 male). There was a clear 3.2 +/- 4.8% (mean +/- 90% confidence limits) increase in Hb(mass) following LHTL compared with Placebo, whereas the corresponding change of -1.4 +/- 4.5% in IHE was unclear. Following LHTL, running economy was 2.8 +/- 4.4% improved compared to IHE and 3mM [La] running speed was 4.4 +/- 4.5% improved compared to Placebo. After IHE, there were no beneficial changes in running economy or 3mM [La] running speed compared to Placebo. There were no clear changes in VO2max, vVO(2max) and TTE following either method of hypoxia. The clear difference in Hb(mass) response between LHTL and IHE indicated that the dose of hypoxia in IHE was insufficient to induce accelerated erythropoiesis. Improved running economy and 3mM [La] running speed following LHTL suggested that this method of hypoxic exposure may enhance performance at submaximal running speeds. Overall, there was no evidence to support the use of IHE in elite triathletes
