Intense physical exertion is known to reduce intraocular pressure (IOP). However, the effect of physical exertion on IOP in the first few seconds after beginning exertion has not been studied previously. IOP was determined twice within 15 s in 32 healthy, young men. Seventeen performed six deep knee bends within 8-10 s preceding the second IOP measurement, while 15 did not. The mean reduction in IOP immediately after such brief and moderate exertion was 1.9 +/- 0.3 mmHg, compared with 0.8 +/- 0.2 mmHg in the control group. The difference between both groups was statistically significant. Thus, even moderate physical exertion may reduce IOP. As the relative decrease in IOP correlated with the relative increase in heart rate, the observed reduction in IOP after brief, moderate physical exertion may be due to sympathetic activity.
众所周知，剧烈的体力活动会降低眼压（IOP）。然而，体力活动开始后的最初几秒内对眼压的影响此前尚未得到研究。在32名健康的年轻男性中，在15秒内对眼压进行了两次测定。17人在第二次眼压测量前的8 - 10秒内进行了6次深屈膝动作，而15人未进行。与对照组眼压平均降低0.8±0.2 mmHg相比，这种短暂适度运动后眼压立即平均降低了1.9±0.3 mmHg。两组之间的差异具有统计学意义。因此，即使是适度的体力活动也可能降低眼压。由于眼压的相对降低与心率的相对增加相关，短暂适度体力活动后观察到的眼压降低可能是由于交感神经活动所致。
