“At the calculated threshold, power (spirulina = 190 ± 39 Watts vs. placebo = 190 ± 37 Watts), VO2 (spirulina = 33.4 mL/min/kg ±6.2 vs. placebo = 32.7 ± 6.0 mL/min/kg), RPE (spirulina = 12.9 ± 1.3 vs. placebo = 13.2 ± 1.1) and RER (spirulina = 1.01 ± 0.03 vs. placebo = 1.00 ± 0.04) were not significantly different (p = 0.857, p = 0.352, p = 0.160, and p = 0.292, respectively) following either spirulina or placebo ingestion.”
