1 Property Activity increase with more exhausting Up to limited level in athletes 2 N Requirement 2.1 Energy: 18.4MJ/d CP:EE: CH2O = 1:1:4 2.2 Protein: 1.5-2.5g/kgBW 2.3 Mineral

CH2O ：Directly supply energy Fat Less utilization than CH2O about 10-20% Protein being acid meterials

3 Dietary guidline for sport -High Level of CH2O -Low level of fat -Suitable level protein -Enough water drinking -Suitable dietary amount -Familiar foods -Good sanitation

4 Sport nutrition eg Students in the university/college 4.1 GE: 3000 - 6000kcal/d 4.2 Ratio of Energy: Carb:Prot:Fat = 4：1：1

4.3 Important of CH2O CH2O in Dietary Menu is very important 55-60%, 9-10g/kg BW such as cereals, fruits and vegetables CH2O be divided into ：Keeping blood glucose level Especially after sports Supporting enough energy to brain and heart

Sutable level in diet: 25-30％/DRIs Causes 高脂肪食物胃停留时间长 脂肪转换成能量所时间长 脂肪分解代谢为不完全氧化 β氧化-酮体: 乙酰乙酸、β-羟丁酸、丙酮 Poor sport level 4.4 Lipids

4.5 Protein E/prot： >15%/DRIs， 1.5-2.5g/kg BW 50% from better prot. Less prot.: Body prot. Exhausted Body status not keeping Over prot.: More acid meterials in body Muscle be tired easily Poor sport level
