Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
At session 1 (-6 weeks) all eligible participants will complete a beep test session which will be used to match subjects according to their DOMS response and anthropometric data (height, weight, body mass index, activity and training history). This will enable matching of participants before randomisation to minimise inter-individual variability. Participants will then be randomly assigned active or placebo medication by a computerised random number generator and matched up by an independent party to allow double blinding.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be conducted by computer. Patients and investigating staff will be blinded to treatment allocation.
Masking / blinding
