长期以来,在学校课余运动训练中,经常会发生这样的情况:为了应付区、县、市级举行的各种竞赛,许多学校往往选择一些运动基础较好,而缺乏系统训练及全面训练不够的学生进行短期集训,运动量和强度上升很快,或在平时的课余训练中一味追求大运动量。因而引起过度训练。一、过度训练的病理机制和发病原因一方面由于连续大运动训练造成机体长久性疲劳,使大脑皮层兴奋与抑制过程之间的均衡性遭到破坏。使原来的动作技能丧失和引起组织器官系统功能失调;另一方面作用于机体的各种生理刺激物超过了一定限度,导致生理应激刺激变成病理刺激,在这种环境长期影响下可造成皮层下功能紊乱,而出现一系列病症。
For a long time, in school after-school sports training, it often happens that in order to cope with various competitions held at districts, counties and municipalities, many schools often choose some sports bases which are better and lack of systematic and comprehensive training Short-term training for students to exercise, exercise and strength increased rapidly, or blindly in the usual after-school training to pursue a large amount of exercise. Thus causing over-training. First, the excessive training of pathology and pathogenesis On the one hand due to continuous large-scale exercise training caused by long-term body fatigue, the cortex of excitement and inhibition of the balance between the process has been destroyed. So that the original loss of motor skills and cause organ dysfunction; the other hand, the role of various physiological stimuli in the body over a certain limit, resulting in physiological stress stimuli into pathological stimuli in this environment can cause long-term effects Cortical dysfunction, and a series of symptoms.
