Description of intervention(s) / exposure
A double blind randomized parallel trial, placebo controlled study will be conducted in which male and female subjects who achieve less than an estimated 1000 kcal/week activity threshold, will supplement their normal daily lives with either Fucoidan (500mg oral tablets, twice daily), or placebo (gelatin filled oral tablets, twice daily), for 6 weeks.
Prior to and after the 6 week supplement period, participants will have a strength assessment conducted at La Trobe University strength and conditioning gym (Bendigo campus), supervised by qualified exercise physiologists. These 2 sessions will involve a health screen, DEXA analysis of body composition, 1 rep max (1RM) back squat strength test and an anaerobic capacity Wingate test. This will require a session time for each participant of 60 min, a total of 2 hours.
To monitor adherence, we will be monitoring returned pill counts and activity journals provided by the participants.

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
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 in the absence of exercise, a novel Fucoidan blend increased muscle mass. While the animal study evidence does exist for Fucoidan influencing 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 muscle health and lean body mass in healthy human subjects not participating in any form of exercise. We hypothesize that fucoidan could be a supplement that increases muscle strength without a need for exercise. Here we propose a study designed to establish whether a novel fucoidan blend can improve muscle and body health in sedentary participants.
