One probably stunning symptom is sudden weight acquire throughout a coaching cycle. As Coates explains, when an athlete is constantly dwelling in a caloric deficit, metabolic disruptions can happen and the physique shifts into hunger mode. Regardless of consuming much less, runners might discover themselves gaining weight. With out information of RED-S syndrome and common checkups, even runners who think about themselves fairly common in means might unknowingly set themselves up for disordered consuming–one thing that many feminine endurance athletes (together with ultrarunners Lucy Bartholomew and Amelia Boone and Olympic marathon bronze medallist Molly Seidel, amongst others) have shared their experiences with through social media in recent times.
When rising their coaching load, athletes ought to ensure that to extend their caloric consumption. As an alternative of working from the mentality that leaner is healthier, runners have to do not forget that getting stronger requires extra gas. Attempting to coach in a steady state of low vitality availability will invariably result in disappointment, lack of motivation, and doubtlessly additionally to physiological and neurological injury.
