目的
以确定两种亚型的iYPS模型是否得到来自一系列生理、行为和心理测量的证据的支持。
方法
有15名高尔夫球手在推杆时出现YIPS症状(平均年龄58.1岁，SD 13.6岁)，9名没有YIPS症状的高尔夫球手(平均年龄39.6岁，SD 19.3岁)被纳入研究对象。参与者完成了一份高尔夫球史问卷，以确定他们的打球经历和任何YIPS症状的性质。在实验1中，参与者执行推杆任务，同时记录双侧前臂屈伸肌和二头肌的肌电数据。这项任务分两个阶段进行，在低压和高压实验条件下进行。这种高压状态的目的是通过使用金钱激励、对业绩进行录像以及提供负面反馈的邦联成员的存在来增加焦虑。在每次实验之前，参与者都会通过问卷调查来评估他们的焦虑状态。在实验2中，参与者完成了一项需要抑制预期反应的任务。确定了它们的准确性和抑制其反应的能力。
结果
根据是否报告主要与运动相关的症状(类型I)或与焦虑相关的症状(类型II)，可以对经历过IPS的高尔夫球手进行分类。I型组在推杆过程中表现出更多的肌肉活动，更多的错误和更少的预期反应任务的抑制。类型II组在认知焦虑和预期反应任务的正常表现方面表现出更大的变化。
结论
这项研究提供了支持两种YIPS亚型的证据。类型I与运动启动和执行能力受损有关，而类型II与操作焦虑有关。
PURPOSE
To determine whether a model of two subtypes of yips is supported by evidence from a range of physiological, behavioral, and psychological measures.
METHODS
Fifteen golfers who experience yips symptoms while putting (mean age 58.1 yr, SD 13.6 yr), and nine golfers with no yips symptoms (mean age 39.6 yr, SD 19.3 yr) were recruited. Participants completed a golf history questionnaire to determine their playing experience and the nature of any yips symptoms experienced. In experiment 1, participants performed a putting task while electromyographic data were recorded from the forearm flexors and extensors and biceps brachii, bilaterally. The task was performed in two sessions, under low-pressure and high-pressure experimental conditions. The high-pressure condition was intended to increase anxiety through the use of a monetary incentive, video-taping of performance, and the presence of a confederate who provided negative feedback. Participants' state of anxiety was assessed using a questionnaire before each of the experimental sessions. In experiment 2, participants completed a task that required the inhibition of an anticipated response. Their accuracy and ability to inhibit their response was determined.
RESULTS
The golfers who experienced yips could be categorized according to whether they reported mainly movement-related symptoms (Type I) or anxiety-related symptoms (Type II). The Type I group exhibited greater muscle activity during putting and greater errors and less inhibition of the anticipated response task. The Type II group exhibited greater changes in cognitive anxiety and normal performance of the anticipated response task.
CONCLUSION
This study provides evidence in support of two yips subtypes. Type I is related to impaired movement initiation and execution, whereas Type II is related to performance anxiety.
