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.

Allocation to intervention
Randomised controlled trial
Query!
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.
Query!
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/)

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.

Summary
Brief summary
Nutritional supplements are routinely ingested throughout a training period to maximise exercise-based adaptations. Edible seaweeds (macroalgae) have the potential to provide a rich and sustainable source of macronutrients and micronutrients to the human diet. The recent surge of interest in seaweed is fueled by attention on the bioactive components of seaweed, which have potential applications in the food and nutraceutical industries, with impetus toward the reducing cholesterol and improving blood sugar levels. One candidate bioactive compound of interest is the polysaccharide, Fucoidan. Fucoidans are found in brown seaweeds and the health benefits of Fucoidans have been demonstrated in both human and animal studies where the multiple effects include anti-inflammatory, anti-oxidant, anti-tumour, and immune-modulating properties. Our research group in collaboration with industry leading Fucoidan producers (Marinova Pty Ltd) have shown in a pre-clinical study in mice that a novel Fucoidan blend increased muscle mass. While the animal study evidence does exist for Fucoidan imfluencing muscle health, more human evidence (including mechanistic evidence) is needed to evaluate both the nutritional benefit conferred and the efficacy of Fucoidan on muscle health. Therefore, the aim of this pilot clinical trial is to evaluate the effect of oral supplementation of a Fucoidan blend on exercise endurance, muscle strength, anabolic parameters and lean body mass in healthy human subjects. We hypothesize that fucoidan could be a supplement that increases muscle strength with greater adaptations when consumed in addition to resistance training. Here we propose a study designed to establish whether a novel fucoidan blend can potentiate the adaptation of muscle to a resistance training protocol.
