PURPOSE: The purpose of this study was to determine if anaerobic performance as measured by the Wingate is decremented in elite female athletes when fraction of inspired @entity26 is decreased from 20.9% to 10%. METHOD: Nine collegiate female soccer players (Mweight  =  63.2      10  kg, Mheight  =  164      4.7  cm, Mage  =  18.6      0.5 year) performed 1 Wingate test under each condition separated by at least 24  hr. @entity26 consumption was measured breath by breath using a Sensor-Medics metabolic cart. Postexercise blood lactates were measured using the finger-stick method. During normoxic and @entity519 (10% inspired @entity26 [ @entity3612 ]) conditions, @entity1 inhaled air from a 300-L weather balloon during the 30-s test. RESULTS: Peak power, minimum power, average power, postexercise blood @entity880 , preexercise and postexercise blood @entity3612 saturation, and total @entity3612 consumed during exercise and during recovery were not statistically different between conditions. However, the Fatigue Index and peak ventilation were significantly greater during @entity519 than normoxia (35      11% vs. 27      9% _ 91.6      14.2  L/min vs. 75.2      11.1  L/min, respectively, p  <  .05, Cohen's d  =  -  0.80 and -  1.29, respectively). Ventilation was elevated during @entity519 within 5  s of beginning the Wingate and remained elevated throughout exercise. This increased ventilation was sufficient to maintain @entity26 consumption during exercise. CONCLUSION: Under @entity519 conditions, the ventilatory response to the Wingate test is perhaps more important than aerobic capacity per se in determining whether or not Wingate performance is decremented.
