磷酸原系统

磷酸原系统的供能能力、糖酵解系统供能速率及其调节能力和机体的抗酸能力是100m运动员加速能力、最大速度能力和速度耐力的限制性因素。

The energy supply capacity of the phosphagen system , the rate of energy supply in the glycolytic system , its adjustment and resistance to acids of the body were the restrictive factors of the sprinters in their endurance , maximum speed and acceleration .

肌肉绝对力量、运动速度，运动中枢同步调节，Ⅱ型肌纤维发展，磷酸原系统供能能力是决定跳远运动员爆发力的生理基础。

The absolute muscle force , movement speed , synchronistic regulation of motor nerve Center , the rate and area of ⅱ type muscle fore , the supplying energy ability of phosphagen system are the physiological foundation of athletes ' power in long jump .

3.100M、200M和400M运动员无氧代谢的特征呈现出显著的项目差异，100M运动员表现出更为优秀的磷酸原系统供能能力，而200M和400M运动员则是乳酸能系统供能占据优势。

100M and 200M and 400M athletes show significant project differences of characteristics of anaerobic metabolism , 100M athletes appears to own more excellent ability of the original system phosphate fuel ability while 200M and 400M athletes have greater advantage over power-supply of lactic acid power system . 4 .

人体有运动时的能量来源有三大途径，即有氧氧化供能系统和糖的无氧酵解供能系统以及磷酸原系统。

The energy provided during body movement comes from three pathways . They are aerobic metabolism , anaerobic metabolism and ATP-CP system .

结合磷酸原系统供能系统的特点合理地安排练习和间歇时间，合理安排力量训练手段的顺序；

Based on the feature of the original phosphoric acid system , we reasonably arrange exercises and intermittent time , and reasonably arrange the order of strength training means .
