Statistical methods / analysis
There has been no previous trial examining the effects of saffron on physical and mental recovery in recreationally-active adults. In this exploratory trial, a convenience sample size of 60 adults will be recruited. If an effect size of 0.7 compared to the placebo is obtained, this will give an 80% chance of finding an effect at a statistical significance of 0.05 (after dropouts).
