The current double blind, randomized, placebo-controlled trial with two parallel groups aimed to assess the impact of whey protein supplementation on recovery of muscle function and muscle soreness following eccentric exercise. During a 9-day period, forty recreationally active males received twice daily supplementation with either whey protein (PRO; 60 g/day) or an iso-energetic amount of carbohydrate (CON). Muscle function and soreness were assessed before, and 0, 3, 24, 48, and 72 h after performing 100 drop jumps. Recovery of isometric maximal voluntary contraction (MVC) did not significantly differ between groups (timextreatment,P= 0.56). In contrast, the recovery of isokinetic MVC at 90 degrees center dot s(-1)was faster in CON as opposed to PRO (timextreatment interaction,P= 0.044). Recovery of isokinetic MVC at 180 degrees center dot s(-1)was also faster in CON as opposed to PRO (timextreatment interaction,P= 0.011). Recovery of countermovement jump performance did not differ between groups (timextreatment interaction,P= 0.52). Muscle soreness, CK and CRP showed a transient increase over time (P
