Oxygen nanobubbles (ONB) have been implicated in enhancement of oxygen delivery to a variety of tissues. Recently, ONBs have become commercially available and are marketed for recreational use prior to exercise in efforts to improve performance. Since phosphocreatine resynthesis is largely limited by oxidative ATP production, ONBs may serve as a means to improve oxygen delivery and recovery during anaerobic exercise. The purpose of this study was to elucidate the effects of ONB ingestion on repeated sprint performance. Physically active females participated in two counterbalanced repeated sprint trials each with a different condition: 1) Placebo, 2) ONB solution. For each trial, participants consumed their respective treatment 10 minutes before exercise. Following a warm-up, participants completed 3 × 15 second Wingate anaerobic tests (WAnT) separated by 2 minutes of active recovery. Blood [La-] was measured pre- and post-exercise. HR and RPE were measured following each WAnT. Findings showed no differences between treatments for anaerobic capacity (p=0.395), fatigue index (p=0.785), HR (0.331), or RPE (p=0.171). While blood [La-] increased from pre- to post-exercise (p< 0.001), no differences between conditions existed (p=0.270). These findings suggest ONBs may not be a viable ergogenic aid for anaerobic exercise.
