Abstract

The purpose of this study was to determine if a seven-day live high–train low (LHTL) simulated altitude exposure could improve (a) anaerobic and/or aerobic capacity (VO2peak) in trained cyclists (n = 10) and (b) VO2peak and/or 400m swimming performance in collegiate swimmers (n=8).

In procedures approved by the EMU Human Subjects Review Board, cyclists performed seven cycle ergometer trials to measure maximal mean power output (MMPO4min), maximal accumulated oxygen deficit (MAOD), and VO2peak, whereas swimmers completed five incremental arm ergometer trials (VO2peak) and 400m swimming performance trials before and after LHTL. No significant changes were observed in any measured parameter. Therefore, the conclusion of this study is that a 7- day simulated altitude exposure of 2,500m for 8.5 hours each night is insufficient to result in changes in MAOD, VO2peak, or performance among highly trained cyclists and swimmers. iii
