足球运动是一项非周期性、对抗性的运动项目,具有运动强度大、运动时间长的特点。从身体的供能方式上来讲,足球运动主要是间歇性的糖酵解供能(LA)和磷酸元供能(ATP-CP),在间歇期间主要是有氧氧化供能来恢复和调整呼吸。从供能的底物上来讲,主要是供能速度较快、能量输出功率较高的肌糖原和肝糖原储备。而在偶尔的冲刺过程中,则需要磷酸元的储备作为保障。训练与营养向来都是相辅相成的,青少年足球运动员的营养需求要结合项目特点和青少年生长发育的特点。一、碳水化合物碳水化合物俗称糖,是人体内的主要能源物质,是骨骼肌进行活动的主要能源物质。从项目特点上来看,足球是十分依赖
Football is a non-cyclical, confrontational sports, with exercise intensity, long-term movement characteristics. From the body’s energy supply terms, football is mainly intermittent glycolysis (LA) and phosphate energy (ATP-CP), in the intermission is mainly aerobic oxidation energy to restore and adjust breathing . From the energy supply of the substrate is concerned, mainly for energy faster, higher energy output of muscle glycogen and glycogen reserves. In sporadic sprint process, you need phosphate reserves as a guarantee. Training and nutrition have always been mutually reinforcing. The nutritional needs of young football players should be combined with the characteristics of the project and the characteristics of adolescent growth and development. First, carbohydrates Carbohydrates commonly known as sugar, is the body’s main energy substances, is the main energy source for skeletal muscle activities. From the project characteristics point of view, football is very dependent
