Exercise is a stressor that induces various psychophysiological responses, which mediate cellular adaptations in many organ systems. To maximize this adaptive response, coaches and scientists need to control the stress applied to the athlete at the individual level. To achieve this, precise control and manipulation of the training load are required. In 2003, the authors introduced a theoretical framework to define and conceptualize the measurable constructs of the training process. They described training load as having 2 measurable components: internal and external load. The aim of this commentary is to extend, clarify, and refine both the theoretical framework and the definitions of internal and external training load to avoid misinterpretation of this concept.
运动是一种应激源，可引起各种心理生理反应，从而介导许多器官系统的细胞适应。为了使这种适应反应最大化，教练和科学家需要在个体水平上控制施加给运动员的应激。为了实现这一点，需要精确控制和操纵训练负荷。2003 年，作者提出了一个理论框架来定义和概念化训练过程的可测量结构。他们将训练负荷描述为具有 2 个可测量的组成部分：内部和外部负荷。本评论的目的是扩展、澄清和完善理论框架以及内部和外部训练负荷的定义，以避免对这一概念的误解。
