Plain English Summary
Background and study aims
Recently, there has been a lot of interest in the effects of essential oils on athletic performance and health. Essential oils are natural oils which are taken from plants and other natural sources. They have been used for many years in alternative medicine, as they are thought to help improve the function of the mind and body. This study will look at oils from the Clinopodium serpyllifolium (white micromeria - a type of evergreen shrub) and Cymbopogon citratus (lemon grass) plants to find out if they are able to improve lung function and athletic performance in healthy male athletes.
Who can participate?
Healthy male university students aged between 18 and 22 from the faculty of physical education at An-Najah National University in Nablus-Palestine.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group inhale Clinopodium serpyllifolium volatile oil mixed with 2ml of normal saline (salt water) which has been turned into a vapor. Those in the second group inhale Cymbopogon citratus volatile oil mixed with 2ml of normal saline (salt water) which has been turned into a vapor. Before and five minutes after inhalation, participants complete a breathing test using a spirometer (device used for measuring the about of air breathed in and out) to test their lung function. In addition, before and after inhalation, participants run 800 metres in a stadium to find out if inhaling the oil will improve their athletic performance.
What are the possible benefits and risks of participating?
Participants may benefit from improved lung function and athletic performance as a result of taking part in the study. There are no notable risks involved with taking part in this study.
Where is the study run from?
An-Najah National University (Palestinian Territory)
When is the study starting and how long is it expected to run for?

Lung function and exercise performance
Intervention
Twenty male university students from the faculty of physical education at An-Najah National University in Nablus-Palestine will be randomly assigned into two different groups. The study is single blind at participant level.
Group 1: Participants will nebulize with Clinopodium serpyllifolium oil (0.02ml/kg of body mass of oil) mixed with 2ml of normal saline.
Group 2: Participants will nebulize with Cymbopogon citratus oil (0.02ml/kg of body mass of oil) mixed with 2ml of normal saline.
Participants in both groups will complete a 800 m run test in a stadium race before and after inhalation of the oils, they will inhale the oils five minutes before running. Lung function tests will be undertaken using a spirometer before and 5 minutes after inhalation.
