Pairwise comparisons indicated significant increases in PP (p=0.009) and MP (p=0.013) for HYP/C compared to HYP. There was a significant difference in PP (p=0.036), MP (p=0.005) and VO 2 (p=0.046), and no significant difference in HR (p=0.385) and FI% (p= 0.555) between all conditions. RESULTS: A repeated measures ANOVA was used to evaluate differences between each condition for each dependent variable. Following the loading phase, each participant completed another WIN test in acute hypoxia (HYP/C). Thereafter, all participants completed a 7-day loading phase of CrM (20-g per day taken in 4, 5-g doses at least 3-hrs apart). separated the normoxic and acute hypoxic WIN tests and the order of air conditions was randomly assigned. For the acute hypoxic condition, participants inspired a 13.7% O 2 air mixture for 5-min before, then during the WIN test. METHODS: Fourteen healthy, college-aged athletes consisting of 10 males and 4 females completed 2 separate 30-s Wingate (WIN) tests in normoxic (NORM) and acute hypoxic (HYP) conditions without CrM supplementation.

PURPOSE: To determine the effect CrM supplementation on peak power (PP), mean power (MP), fatigue index (FI %), heart rate (HR), and oxygen uptake (VO 2) during acute hypoxic exercise performance. However, there is inadequate research on CrM supplementation and its effect on hypoxic performance. Many studies have been done on both subjects. Creatine monohydrate (CrM) supplementation is known to increase anaerobic power. SilversĮxercise at altitude under hypoxic conditions is known to decrease maximal aerobic power and shift ATP production toward anaerobic energy systems.
