Spirulina Supplementation In Recovery From Damaging Exercise
Sponsor: University of Exeter
Summary
Exercise can cause muscle damage, leading to a loss in muscle function, increased muscle soreness and inflammation. Evidence supports the use of nutritional strategies to help recovery. Spirulina is a type of algae. It is eaten as a food supplement as it is full of micronutrients, some which provide anti-inflammatory benefits. This work will assess the impact of taking spirulina supplements on recovery from hard exercise. Investigators will measure changes in muscle function, soreness and markers of inflammation.

Interventions
Spirulina supplement
Participants consume a 3g spirulina supplement 3 times daily for 5 consecutive days.
Eccentric exercise
On the morning of Day 3 (where Day 1 is when participants start taking supplements), participants perform a single bout of eccentric exercise. The exercise protocol is performed on a single leg and involves 300 (10 sets of 30 repetitions separated by 120 seconds) voluntary maximal, isokinetic, eccentric contractions of the knee extensor. Exercise is performed using a Biodex System 3 isokinetic dynamometer (Biodex Medical Systems, Shirley, NY, USA), and contractions are performed at 60◦/s over an 80◦ range of motion.
Placebo supplement
Participants consume a macronutrient matched placebo supplement 3 times daily for 5 consecutive days.
