During the study, researchers conducted tests of aerobic exercise and mental fatigue tests based on mathematics, and also asked subjects to evaluate their own feelings of daily fatigue.

The study was financially supported by Cyanotech -. Producer of spirulina and other food products derived from cyanobacteria and other algae
