Energy balance

Post-exercise ingestion of carbohydrates (8-10 g/kg/day) within 30 minutes maximizes muscle glycogen re-synthesis, and adding protein (0.2-0.5 g/kg/day) at a 3-4:1 ratio further enhances this re-synthesis.

After a hard workout, eat 8-10 grams of carbohydrates per kilogram of body weight within 30 minutes. If you can, add protein (0.2-0.5 g/kg) to create a 3:1 or 4:1 carb-to-protein ratio. This speeds up glycogen recovery, which is crucial if you train again soon.

Post-exercise (within 30 minutes) consumption of CHO at high dosages (8 – 10 g CHO/kg/day) have been shown to stimulate muscle glycogen re-synthesis, while adding PRO (0.2 g – 0.5 g PRO/kg/day) to CHO at a ratio of 3 – 4:1 (CHO: PRO) may further enhance glycogen re-synthesis.
