Values are expressed as mean ± SD.
MIPS: Multi-Ingredient Performance Supplement; CON: Control Carbohydrate Placebo; MVC: Maximal Voluntary Isometric Contraction; ROM: Range of Motion; DHR: Downhill Run; POST: Immediately Post-DHR.
*p < 0.05, significant time effect.
^a p < 0.05, significantly different from Pre.
^b p < 0.05, significantly from POST.
^c p < 0.05, significantly different from 24 hr.
^d p < 0.05, significantly from 48 hr.
