Description of intervention(s) / exposure
Intervention Group 1: Perna canaliculus (green lipped muscle) – capsule form (50mg per capsule). Dosage 2 oral capsules in the morning and evening with meals for eight weeks prior to the down hill run and for three days after.

Intervention Group 2: Harpagophytum procumbens (Devil’s Claw) – liquid form (500mg per millilitre). Dosage 10ml orally daily for six weeks prior to the down hill run and four days after.

Intervention Group 3: Arnica Gel (10mg per gram) – topical application, directions to rub into the quadriceps straight after the down hill run and then every four hours (excluding sleeping hours) for five consecutive days.

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.

Summary
Brief summary
Delayed Onset Muscle Soreness (DOMS) and muscle damage are common and expected self-limiting sports training related conditions that can result in a loss of muscle force and significant pain. For athletes required to train and compete in close succession, DOMS can pose an obstacle to optimal performance. At present there are multiple methods for treating DOMS. Methods include; cryotherapy, anti-inflammatory medications, stretching, hypo-baric oxygen therapy, homeopathy, ultrasound, E-stimulation, L-carnitine, rest and light exercise. To date, a sound and consistent treatment for DOMS has not been established.

High-quality scientific research into Complementary and Alternative Medicines (CAM) and DOMS is limited despite the increase usage of such products by athletes. This is a randomised, double blind, placebo controlled trial that looks at four selected CAM’s in four sub-studies and their effect on DOMS and muscle damage in sub-elite athletes.
