The two-visual-system hypothesis (TVSH) provides a framework for understanding the nature of the visual information athletes are likely to rely on during competition. If valid, the framework provides a valuable means of evaluating the likely efficacy of different vision training tools that claim to improve the sport performance of athletes.The TVSH has been used to explain that many of the existing methods of testing and training vision may be ineffective to improve on-field sport performance. The TVSH suggests that the visual pathway used to control actions on-field may be different-and rely on different visual information-to the pathway often tested and trained off-field. However, the central claims of the TVSH are increasingly questioned, and this has implications for our understanding of vision and sport performance. The aim of this article is to outline the implications of the TVSH for the visual control of actions in sport. We first provide a summary of the TVSH and outline how the visual information used to control actions might differ from that usually tested. Second, we look at the evidence from studies of sports that are (and are not) consistent with the TVSH and the implications they have for training vision. Finally, we take a wider look at the impact of the TVSH on the sport sciences and other complementary theories that hold implications for training vision to improve sport performance.
双视觉系统假说（TVSH）为理解运动员在比赛中可能依赖的视觉信息的本质提供了一个框架。如果该假说成立，它将为评估不同声称能提高运动员运动表现的视觉训练工具的可能效果提供一个有价值的手段。TVSH 被用来解释许多现有的测试和训练视觉的方法可能对提高场上运动表现无效。TVSH 表明，用于控制场上动作的视觉通路可能与场外经常测试和训练的通路不同，并且依赖于不同的视觉信息。然而，TVSH 的核心主张越来越受到质疑，这对我们理解视觉和运动表现产生了影响。本文的目的是概述 TVSH 对运动中动作视觉控制的影响。我们首先总结了 TVSH，并概述了用于控制动作的视觉信息可能与通常测试的信息有何不同。其次，我们研究了与 TVSH 一致和不一致的运动的证据，以及它们对视觉训练的影响。最后，我们更广泛地探讨了 TVSH 对运动科学和其他对提高运动表现有影响的补充理论的影响，这些理论对训练视觉有影响。
