The study will assess the recovery and performance of young athletes suffering from muscle damage induced by physical exercise. Model by comparing the safety and efficacy of ReWin(d) supplemention during 4 weeks to placebo over 72 hours post exercice.

Double-blind, randomized, placebo controlled, parallel group, pilot safety and efficacy study.

40 healthy young male athetes were randomly assigned to the ReWin(d) or Placebo group. After 4 weeks supplementation (either 2 g daily of ReWin(d) capsules or placebo capsules). the participants were subjected to a 1 hour plyometric exercise session to induce DOMS. At 0 hours, 24 hours, 48 hours and 72 hours post exercise, the volunteers have been assessed to determine: (i) pain perception, (ii) fatigue rate, (iii) sport performance (effectiveness of a jump) and (iv) muscle damage and inflammation by I-R thermography and biomarkers
