Abstract

The purpose of this study was to clarify whether the intake of oxygenated water before the start or exercise had an influence on cardiorespiratory responses during exercise. Ten male university long distance runners participated in the present study. We adopted a randomized, double blind, placebo controlled and crossover design for this experiment. The measurements of cardiorespiratory parameters such as oxygen uptake, carbon dioxide output, expired minute ventilation, arterial oxygen saturation, heart rate and exhaustion time during submaximal and maximal exercises were performed during a treadmill running test. Subjects consumed either the placebo, 350 ml of plain water, or 350 ml of water with an enriched oxygen content of 30 ppm within 15 minutes before the start or the test. As for maximal oxygen uptake and exhaustion time, significant differences were not detected in the measurements between subjects who drank oxygenated water and those who took the placebo [mean (SD) 68.8 (3.2) vs 69.0 (3.4) ml/kg/min, 566.7 (35.2) vs 570.4 (42.0) s]. The other variables also did not show any significant differences. These results suggest that the consumption of oxygen enriched water before exercise could not affect cardiorespiratory responses during exercise.
