Description
The purpose of this study was to determine the effect of oxygenated water on endurance exercise performance. Subjects (N=15, VO2max 54.8 +/- 5.8 ml/kg/min) were tested using non-oxygenated water (PL) and oxygenated water (OW). Two maximal exercise tests and 2 submaximal tests were conducted. VO2max (3.28 +/- 0.81 L/min (OW) vs. 3.30 +/- 0.80 L/min (PL)) VE, VO2, or R were not different. Submaximal blood lactate values at 60%, 80% of VO 2max (4.2 +/- 2.1 mMol/L, 6.6 +/- 2.9 mMol/L (OW) vs. 3.8 +/- 1.8 mMol/L, 6.1 +/- 2.4 mMol/L (PL)) and HR (140 +/- 15 bpm, 162 +/- 11 bpm (OW) vs. 138 +/- 15 bpm, 163 +/- 13 bpm (PL)) were not different and neither was time to exhaustion at 90% of VO 2max (5.22 +/- 2.31 min (OW) vs. 6.80 +/- 2.93 min (PL)). Oxygen content of OW (13.1 +/- 1.5 mgO2L-1 ) was higher than PL (6.0 +/- 0.1 mgO2L -1) (p<0.05) but lower than manufacture's claims. Thus, superoxygenated water did not result in any improvements in endurance exercise performance.
