The literature regarding the effect of exercise on pain is equivocal. The purpose of this investigation was to quantify the influence of an acute bout of exercise on pain threshold (PT) and pain ratings (PR). A secondary purpose was to measure heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and state anxiety (SA) responses. Pressure (3000-g force) was applied to the middle digit of the right forefinger for 2 min with the Forgione-Barber pain stimulator before and following (5 min of cycling at 75% VO2max. Quiet rest consisted of sitting quietly for 30 min in a sound-dampened chamber. Order was counterbalanced, randomly assigned, and performed on different days. Data was analyzed with a repeated measures ANOVA for multifactor experiments. PT was significantly higher (P < 0.05) and PR were significantly lower (P < 0.05) in the exercise condition 5 min post-exercise in comparison with quiet rest. Changes in pain perception were accompanied by lower SBP (P < 0.03) and higher HR (P < 0.0001). in the exercise condition. It is concluded that an acute bout of exercise is associated with changes in pain perception.
关于运动对疼痛影响的文献尚无定论。本研究的目的是量化一次急性运动对疼痛阈值（PT）和疼痛评分（PR）的影响。第二个目的是测量心率（HR）、收缩压（SBP）、舒张压（DBP）和状态焦虑（SA）反应。在运动前和运动后（以75%最大摄氧量进行5分钟骑行），使用Forgione-Barber疼痛刺激器对右手食指中指施加压力（3000克力）2分钟。安静休息包括在隔音室内安静地坐30分钟。顺序进行了平衡、随机分配，并在不同日期进行。数据采用多因素实验的重复测量方差分析进行分析。与安静休息相比，运动后5分钟的运动状态下PT显著更高（P < 0.05），PR显著更低（P < 0.05）。疼痛感知的变化伴随着运动状态下较低的SBP（P < 0.03）和较高的HR（P < 0.0001）。得出的结论是，一次急性运动与疼痛感知的变化有关。
