一、短跑运动的代谢反应短跑运动是一种高强度的运动,这种类型的运动只能维持很短的时间。它的能量供应主要来源于糖的无氧酵解系统,能量供应是在缺氧的情况下完成的。经过研究测定:男子短跑选手在40米、60米、80米、100米全速跑前后的肌肉中ATP、磷酸肌酸和乳酸浓度变化。在40米、60米、80米跑中,最快的短跑选手利用磷酸肌酸量最大,大部分磷酸肌酸在运动的前5～6秒就消
First, the metabolic reaction of sprint exercise Sprint exercise is a high-intensity exercise, this type of exercise can only be maintained for a short period of time. Its energy supply comes mainly from the sugar anaerobic glycolysis system, the energy supply is done in the absence of oxygen. After the study determined: ATP, Creatine and Lactic acid concentrations in muscles of men sprinters before and after 40 m, 60 m, 80 m, 100 m full speed running. In the 40 meters, 60 meters, 80 meters run, the fastest sprinters use the largest amount of creatine phosphate, most of creatine phosphate in the first 5 to 6 seconds of exercise to eliminate
