Background: Essential oils have gained massive attention. We aimed to assess the effects of inhalation ofClinopodium serpyllifolium and Cymbopogon citratus volatile oils on exercise performance and lung function.Methods: Twenty physical education students were randomly assigned into two groups: Clinopodiumserpyllifolium and Cymbopogon citratus (10 participants each). One group was nebulized with Clinopodiumserpyllifolium oil and the other by Cymbopogon citratus oil at a concentration of (0.02 ml/kg of body mass)which was mixed with 2 ml of normal saline before 800 m running tests. Lung function tests were measured usinga spirometer pre and post nebulization.Results: There was a significant increase in Forced Expiratory Volume in the first second and Forced Vital Capacityafter inhalation of both oils. The normal spirometry after inhalation of C. serpyllifolium oil increased by 30%.A sharp decrease in mild spirometry (50% before to 10% after inhalation of the C.citratus oil) was observed.Significant reductions in the means of the running time were observed.Conclusion: Our findings support the effectiveness of C. serpyllifolium and C. citratus essential oils on exerciseperformance and respiratory function parameters.
