PROTEIN

The hypothesis behind recovery:

Recovery -“window of opportunity”

Recommendations:

Consume 10-20 g of protein within the first 60 minutes after running.

Preferably combine 1.0-1.2 g/kg BM of carbohydrate.

Example food portions:415 g Baked Beans = 20 g of protein

300 ml skimmed milk = 10 g of protein1 Lucozade Recovery drink = 10g protein

+ 22.5 g Carbohydrate
