在400米和800米等中长距离的项目训练过程中,糖酵解系统供能所占的比例较大,是训练的核心部位,也是提高成绩的关键环节,如:在400米跑过程中,磷酸原系统供能占20%~25%,糖酵解系统供能占55%~65%,有氧系统供能占15%~25%。800米跑磷酸原系统供能占30%,糖酵解系统供能占65%,有氧系统供能占5%。从数据上来看,糖酵解系统供能具体重要地位,在速度训练过程中,糖酵解的代谢产物主要是乳酸,乳酸的产生速度,堆积程度、消除速度是影响运动员后程速度快慢的三个
In 400 meters and 800 meters and other long-distance training in the project process, the glycolysis system to a larger proportion of energy supply is the core of the training, but also improve the performance of the key elements, such as: 400 meters in the process of running , Phosphoric acid system for energy accounts for 20% to 25%, glycolysis system for energy accounted for 55% to 65%, aerobic system for energy accounted for 15% to 25%. 800 meters to run the original system of phosphoric acid for 30%, glycolysis system for 65%, aerobic system for 5%. From the data point of view, the glycolysis system to supply a specific important position in the speed training process, glycolysis metabolites are mainly lactic acid, lactic acid production rate, accumulation, elimination rate is the impact of athletes speed of the latter three A
