Effects of Sulforaphane Supplementation on Athletic Performance

Considering the promising effects observed and the scarce and incipient scientific background of SFN in sports, the present study aims to evaluate the effects of SFN supplementation on fatigue, EIMD and recovery in trained individuals. In particular, outcomes such as time to exhaustion (TTE), and perceptual questionnaires of muscle soreness, recovery, and fatigue will be assessed, aiming to explore the effectiveness of SFN.
