• Exercise intensity

• Exercise duration

• Training status

• Low carbohydrate diet

• Dehydration (> 3 % BM)

• Very high carbohydrate diets (> 70% EI)

Therefore understanding individual carbohydrate

availability would prove beneficial for product innovation

and recommendations

“So I have put the players on a low carbohydrate diet to improve how they adapt to training, which is a good thing. But they will probably run slower and generally be more sluggish during training. Hope you are ok

with that!”
