Purpose. There is little information regarding the effect of simulated altitude via a rebreathing apparatus on interval performance. Therefore, the purpose of this experiment is to examine how interval performance is affected with acclimatization to simulated altitude. Methods. A total of 17 subjects participated in the experiment; however, 1 was discarded due to noncompliance with the hypoxia treatment. The subjects were asked to have blood drawn by the Miami University Health Center for examination of hematological values pre-treatment and post-treatment. The subjects performed an initial VO2max, 90% interval test (5 times for 3 minutes maximum of last VO2max stage followed by 3 minute walk), and a repeated Wingate test (15 sec test with 1 minute of recovery 6 times). The treatment consisted of 15 days of 15 minutes a day utilizing a rebreather as a placebo or hypoxia treatment. Following the treatment the hypoxia group was asked to have blood drawn 5 days post-rebreathing to allow for full maturation of erythrocytes. The placebo group was asked to have blood drawn 1 day after rebreathing. The 90% interval test and repeated Wingate test was performed post-treatments. The hypoxia group was asked to perform 5 days post-rebreathing and the control was 1 day post-rebreathing. Results. There was a significant difference between hypoxia group’s pre-test and post-hemoglobin values F = (1, 14,) = 4.60. p = 0.05. There was also a significant change in time during stage 3 of the 90% interval test for the hypoxia group from pre-test to post-test F = (1, 12) = 5.68, p = 0.04. Conclusion. It is concluded that simulated altitude via a rebreathing apparatus has a beneficial affect on performance. The increase in hematological values were correlated with the increase in performance on the 90% interval test
