Just arrived in DenmarkŮ What does RED-S stand for? Ӓelative energy deficiency in sport (RED-S) describes a syndrome of poor health and declining athletic performance that happens when athletes do not get enough fuel through food to support the energy demands of their daily lives and training. RED-S can and does affect athletes of any gender and ability level.Լ/p> Here is a quick one, kind of red ֠s in a nutshell. Hopefully this should and could help lots of people but I would advise for all to do more research into the subject. #reds #altra #run #endurance #ultrarunning #running #health #food #calories #sportsnutrition
