所谓反馈是指控制系统把信息输送出去,又把其作用结果返送回来,并对信息的再输出发生影响,起到控制的作用,以达到预定的目的。反馈包括两种基本形式:凡使系统的输入对输出的影响增大,导致运动加剧的反馈称为正反馈。反之,凡使系统的输出的影响减少,使系统偏离目标的运动逐步收敛的反馈称为负反馈。在体育教学过程中,充分利用反馈原理,能够加速运动技能的形成。
The so-called feedback refers to the control system to send out the information, and then return the results of its role back, and re-output of information have an impact, play a controlling role in order to achieve the intended purpose. There are two basic forms of feedback: those that make the input of the system have more influence on the output, and the feedback that leads to the exacerbation of motion is called the positive feedback. Conversely, any feedback that reduces the influence of the output of the system and gradually moves the system away from the target is called negative feedback. In the process of physical education, make full use of the feedback principle, can accelerate the formation of motor skills.
