本文借鉴当今控制论中的一些基本思想 ,在发展完善“大周期训练理论”过程中 ,将运动训练理解为“运动员体能控制”,并对其中的被控对象变化过程建模、控制目标选定、控制系统设计、系统参数在线调整等具体任务 ,设计了一套切实可行的模型目标训练方法 ,用来实现在大周期中运动员运动功能的有效调节。为这个运动训练方法找到了一个可靠的理论基础。 In this paper, we draw lessons from some basic ideas in current cybernetics. In the process of developing and perfecting the “large-cycle training theory”, we understand the training of athletes as “physical fitness control of athletes”, and model the process of change of controlled objects, , Control system design and online adjustment of system parameters, a set of practical training methods of model target was designed to realize effective regulation of athlete’s motor function in large cycle. Found a reliable theoretical basis for this exercise training method.
