Lactotripeptides supplementations alleviate the decrease in maximal isometric force following high-intensity eccentric exercise: a randomized, placebo-controlled, double-blinded clinical trial

Objective To investigate whether lactotripeptides (LTP) supplementations alleviate the decrease in the maximal isometric force (MIF), an indirect marker of muscle damage, following eccentric exercise (ECC). Design Twenty-two young men performed 50-ECC of the elbow flexors using an isokinetic dynamometer. The subjects were randomly assigned to either the placebo or LTP group, and were each given a 4.5 mg/day placebo or LTP three-time on the exercise day and the day after. MIF and brachial arterial diameter were assessed before and two days after the ECC. Results The interaction of time and group on MIF was significant (p
