What is the recommended intake of carbohydrate during intermittent, high-intensity sports?

I think the recommended intake of carbohydrates during intermittent, high-intensity sports is 7-12 g/kg Body weight daily. For very high intensity training (4 hrs) is 10-12 g / kg BW daily, while for moderate intensity training (about 1 hour daily) is 5-7 g / kg BW daily and for very light training is about 3-5 g / kg BW daily.
