Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The active treatment will be in the form of a 600ml sports drink containing 100mg cannabidiol (CBD). One 600ml drink is to be consumed by participants each day, orally (total dose 100mg CBD/day) for the 12-day treatment period.

At V0 the participants will be supplied with a bottle containing the 12 days’ supply of the treatment, with 3 reserve doses to allow for ± 3 day window to replace lost or damaged dose units. Participants will be required to complete a daily treatment compliance log and will be asked to bring this with them to each testing visit (V1-V5) for checking, as well as returning all unused study medication at V5.
At V1 participants will perform a downhill running maneuver on a treadmill once. The maneuver is moderate in intensity, participants will be required to keep at their VO2 max for 45 minutes. This will be overseen by an authorized researcher from the Department of Health and Medical Science, and performed in the exercise science laboratory at Swinburne University. Participants will be trained in performing the run prior to V1, and monitored continuously throughout the maneuver to ensure adherence to the exercise.

Labels on all treatments will include a list of potential ingredients, batch number, and expiry date and storage/use instructions.

Both treatments and the placebo are identical in appearance. Treatments will be provided in bottles with the participant identification number and treatment day clearly labelled by a disinterested third party. Until dispensed to the participants, the trial products will be stored in a securely locked area, only accessible to authorized personnel.

Summary
Brief summary
Cannabidiol has shown much promise for its immunomodulation and anti-inflammatory properties. The purpose of this trial is to investigate the effects of short-term oral supplementation of cannabidiol (CBD) prior to and following downhill running on serum markers of inflammation and muscle damage, functional recovery and perceived muscle soreness in untrained individuals.
This will be a double blind, randomised, placebo-controlled study comprising two experimental conditions (CBD versus placebo). It is hypothesised that CBD will elicit reduced pro-inflammatory blood markers, reduced recovery time, and reduced subjective muscle soreness compared to placebo.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
It is expected that the results of this trial will be disseminated via peer-reviewed publications and at academic conferences. For these purposes the data will be collated and analysed as group data. If required by the publishing journal, de-identied raw data will be uploaded to an appropriate repository. Otherwise, as the Intellectual Property of this study are owned by the sponsor and may be used for the purposes of commercialisation of the study product, the trial data will not be made available.
