Background: We conducted a blinded placebo-controlled trial to compare the aerosol spray Oxygen Shot™ to that of a water-based placebo, Evian Mineral Water Spray™. Oxygen Shot™ is marketed as oxygenated water. Both aerosol mists were measured to contain 21% oxygen. Our research question was: Will a difference in heart rate, dyspnea or post-exercise improvement be observed between aerobic exercisers utilizing the aerosol mist Oxygen Shot or the placebo?
Methods: We randomly selected 27 subjects from our convenience sample of an aerobic exercise class, 12 were given the placebo-Evian Mineral Water Spray™ and 15 were given Oxygen Shot™. Participants were instructed to utilize the aerosol during the class as desired. Each spray was covered so participants could not identify the aerosol. Measures included; heart rate before, during, and after exercise, visual analog scale for dyspnea, and a post-exercise question regarding the rejuvenation properties of the spray. Compliance with IRB policy was followed.
Results: See Table. More participants using Oxygen Shot™ stated that they were refreshed and rejuvenated with less dyspnea. The t-test determined there was not a significant difference between the two groups at the p < .05 level for post-exercise refreshment.
Summary: Aerosol sprays may be equally effective in reducing dyspnea and refreshing exercisers. Only slight differences in heart rate, VAS dyspnea and refreshment were noted. Oxygen Shot™ was perceived as effective as the placebo for refreshment of exercisers. We recommend this pilot study be replicated with more subjects.
