Values are means ± standard deviations. Multivariate analysis revealed overall Wilks’ Lambda treatment (p = 0.62), time (p = 0.036), and treatment × time (p = 0.53). Greenhouse-Geisser p-levels are reported with univariate analyses for time, treatment, and time × treatment interactions for each variable. PLA = Placebo, RTD = Ready-to-drink Pre-workout supplement, FFM = Fat Free Mass, Trt = Treatment, I = Time × Treatment interaction.
