Abstract

We examined the effect of a proprietary spearmint extract containing rosmarinic acid (PSE) on physical, cognitive, and executive functioning of study participants after a high-risk tactical operation while sleep deprived for 24 hours. Ten Operators (mean ± standard deviation: age, 35.1 ± 5.2 years; height, 177.6 ± 5.3cm; weight, 81.3 ± 9.3kg) from an elite counterterrorism unit volunteered to participate in this randomized, double-blind, parallel-design study. Participants were randomly assigned into either the PSE or placebo (PL) group and ingested 900mg/day PSE or an equivalent amount of PL for 17 days. Physical, cognitive, and executive functioning was tested before PST supplementation (PRE) and within 1 hour of the operation's conclusion (POST). Magnitude-based inferences indicated that differences between PSE and PL in jump power, reactive agility, eye-hand coordination, and cognition were unclear. However, subjective feelings of energy, alertness, and focus were very likely, likely, and possibly better for PSE than PL, respectively. There was no difference (ρ = .64) between groups in identifying the correct target; however, all participants in the PSE group correctly identified the target, whereas 60% of participants in the PL group correctly identified the target at POST. Although the results of this study do not provide conclusive evidence regarding the efficacy of PSE, they do suggest additional research is warranted in a larger sample of participants.
