Displays of anxiety in table tennis were assessed through subjective (a self-report questionnaire), physiological (heart-rate variability) and kinematic variables. Using a within-group crossover design, 9 university-level table tennis players completed a series of serves under low- and high-anxiety conditions. Anxiety manipulation was achieved through the introduction of a national standard table tennis player, known to the participants, to receive serves in the high-anxiety condition, whilst serves were received by no opponent in the low-anxiety condition. Automated motion capture systems consisting of high-speed 3D motion cameras and analytical software (QUALISYS) determined the subject's movement kinematics: bat face angle (degrees) and serve routine duration (s). Self-reported state anxiety (MRF-Likert) and heart rate measurements were collected to examine changes between conditions. Contrary to the hypothesis, bat face angles did not change significantly between anxiety conditions (F (1.8) = 2.791, p = 0.133) and movement times were faster in the high-anxiety condition. In light of these findings, research into other facets of movement behaviour must be analysed to gain further understanding of the effects of anxiety on performance, which remain unclear.
通过主观（一份自我报告问卷）、生理（心率变异性）和运动学变量来评估乒乓球运动中的焦虑表现。采用组内交叉设计，9名大学水平的乒乓球运动员在低焦虑和高焦虑条件下完成了一系列发球。通过引入一名参与者熟知的国家级乒乓球运动员来实现焦虑操纵，在高焦虑条件下由该运动员接球，而在低焦虑条件下则没有对手接球。由高速3D运动相机和分析软件（QUALISYS）组成的自动动作捕捉系统确定受试者的运动学：拍面角度（度）和发球常规持续时间（秒）。收集自我报告的状态焦虑（MRF - 李克特量表）和心率测量数据，以检验不同条件之间的变化。与假设相反，焦虑条件之间拍面角度没有显著变化（F(1.8)=2.791，p = 0.133），且在高焦虑条件下运动时间更快。鉴于这些发现，必须对运动行为的其他方面进行研究，以进一步了解焦虑对表现的影响，目前这些影响仍不清楚。
