Abstract

Purpose: The study investigated the acute responses of altitude (Denver, CO) simulation during high intensity interval training and the subsequent supplementation of oxygen to facilitate greater recovery. Lacking literature on the subject matter is a major consideration for completion of the study. We hypothesize that oxygen supplementation during an acute bout of high intensity interval training with accompanying altitude will allow for greater recovery. Methods: Seven healthy cyclists aged 40.9 +/- 7.01 (Height: 68.4 +/- 4.98: Weight: 171.3 +/- 33.29: 19.3% +/-7.41%: VO2 Max L/min 4.12 +/- 1.17) performed baseline VO2max testing and three subsequent separate randomized trials consisting of three HIIT and recovery intervals with varying conditions. Session A: altitude intervals / supplemental oxygen recovery. Session B: sea level HIIT / sea level recovery. Session C: altitude HIIT / sea level recovery. Trial intensity will be established by cardiac output prediction and set at 75% HIIT and 50% recovery in watts. Results: Supplemental oxygen following HIIT elicited significant responses in HR (p<0.035, p<0.012), VO2 (p<0.029, p<0.030, p<0.004, p<0.001), cardiac output (p<0.012, p<0.002), and right quadricep oxygen saturation (p<0.011, p<0.013, p<0.009). Conclusion: The implementation of supplemental oxygen following altitude simulation with HIIT will facilitate greater recovery. Although significance was found among multiple variables, more subjects are needed for other to become significant.
