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 Citrus sinensis (sweet orange) flower and Mentha spicata (spearmint) leaves 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 20 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 M. spicata oil mixed with 2ml of normal saline (salt water) which has been turned into a vapor. Those in the second group inhale C. sinensis flower 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 (devise used for measuring the about of air breathed in and out) to test their lung function. In addition, before and after inhalation, participants run 1500 metres in a stadium to find out if inhaling the oil has improved 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?
April 2016 to October 2016

Who is funding the study?

Exercise performance and lung function

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 participant level.

Group 1: Participants will nebulize with M. spicata oil (0.02ml/kg of body mass of oil) mixed with 2ml of normal saline.
Group 2: Participants will nebulize with C. sinensis flower oil (0.02ml/kg of body mass of oil) mixed with 2ml of normal saline.

Participants in both groups completed a 1500m run test in a stadium race before and after inhalation of the oils, they inhaled the oils 5 minutes before running. Lung function tests are undertaken using a spirometer before and after inhalation.

Intervention type

Other

Primary outcome measure

Lung function is measured using spirometry before and 5 minutes after inhalation of volatile oil.

Secondary outcome measures

Athletic performance is measured using a 1500 meter run test before and after inhalation of volatile oil.
