Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A double blind randomized parallel trial, placebo controlled study will be conducted in which male and female subjects who regularly weight train (>2 times a week), will perform 6 weeks of strength training with supplement either Fucoidan (500mg oral tablets, twice daily), or placebo (gelatin filled oral tablets, twice daily).

All strength training sessions will be conducted at La Trobe University strength and conditioning gym (Bendigo campus), supervised by qualified exercise physiologists, and involving 2 x 20 minute sessions per week. These sessions will involve a 5-minute dynamic warm-up at an intensity corresponding to 30-50% of 1RM before completing three sets of ten repetitions @70% of 1RM, 2 minutes between sets (weeks 1–2), eight repetitions @80% of 1RM (weeks 3–4), or six repetitions @85% of 1RM (weeks 5–6). This will require a session time for each participant of 20 min, a total of 40 min for the week.

To monitor adherence, we will be monitoring returned pill counts and training session attendance checklists.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Numbers 1-40 will be placed in an envelope. Upon enrolment in the trial, an envelope will be randomly selected and given to the individual. Prior to this, a random sequence of the numbers 1-40 will be generated, with odd numbers (in the sequence) being placebo and even numbers (in the sequence) being fucoidan.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. https://www.random.org/sequences/)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Efficacy
Statistical methods / analysis
Sample size are based on pre-clinical animal and in vitro studies to estimate sample size based on the outcome of change in muscle mass and strength, using a paired samples one-tailed t-test with alpha 0.05 and 80% power

Statistical methods for analysing primary and secondary outcomes will be a general linear estimating model.
