In a randomized, double-blind, placebo-controlled trial, 22 elite male rugby players took 5.7 g of spirulina platensis or placebo for 7 weeks.
There weren't any statistically significant differences in fat mass or other anthropometric parameters between groups. There also weren't differences in concentric or eccentric peak torgue or power from knee extensors or flexors.
There was a greater improvement in squat jump height but not countermovement jump in the spirulina group. There was a greater improvement in 10 and 30-meter sprinting speed as well.
