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.
