体育教学和运动比赛中,在进行主教材和比赛之前做充分的准备活动,对于学生和运动员来说是非常重要的。如果教师忽视或不重视准备活动的指导与组织,往往会引起学生各种身体损伤的出现,造成学生肢体伤害,甚至是产生心理阴影,从而导致学生对体育锻炼的恐惧感。这样,不仅达不到锻炼效果,而且锻炼兴趣也丧失了。因此,体育教师必须教导学生重视每一次运动前的准备活动,在上课和锻炼前,指导学生做好充分的准备活动,使他们的身体由相对的安静状态逐步转入紧张的工作状态,激发中枢神经系统逐渐兴奋,最大限度调动身体机能,使机体尽快适应体育活动。
In physical education and athletic competitions, it is important for students and athletes to prepare well before the main texts and competitions. If teachers neglect or neglect the guidance and organization of preparatory activities, they often cause various physical injuries to students, causing physical injuries to students and even psychological shadow, which leads to students’ fear of physical exercise. In this way, not only fail to exercise, but also lost interest in exercise. Therefore, PE teachers must teach students to pay attention to preparatory activities before each exercise. Before class and exercise, students should be instructed to make adequate preparatory activities so that their bodies gradually change from a relatively quiet state to a tight working state, The nervous system gradually excited, maximize the mobilization of body functions, so that the body adapt to physical activity as soon as possible.
