从中学田径运动会短跑比赛中,可以发现许多200米跑运动员前程速度快、后程速度明显减慢、动作技术变形现象,这是速度耐力差的表现。我国优秀短跑运动员也存在着速度耐力差的薄弱环节。 速度耐力是指保持最高速度的能力。在短跑比赛中,出现后程减速、动作技术变形现象,主要是因为无氧代谢能力下降,使肌体产生疲劳,特别是中枢神经系统疲劳,心血管系统和运动器官机能下降。因此,在进行速度耐力训练时,应着重发展无氧供能系统(磷酸原系统和乳
From the middle school track and field dash game, you can find many 200-meter runners speeding ahead, the latter slowed down significantly, the movement of technical deformation, which is the performance of poor speed endurance. Our country outstanding sprinter also has the weak link of the speed endurance. Speed Endurance is the ability to maintain maximum speed. In the sprint competition, there are post-stroke deceleration and movement of technical deformation phenomenon, mainly due to decreased anaerobic metabolism, the body fatigue, especially in the central nervous system fatigue, cardiovascular system and motor function decline. Therefore, in the course of speed and endurance training, we should focus on the development of anaerobic systems (Phosphate System and Milk
