The aim of the study was to evaluate intraocular pressure (IOP) before and after moderate exercise in normal healthy individuals with defined physical exertion. The second aim of this investigation was to determine the correlation between resting IOP (IOPr) and its change induced by exercise as well as the relationship between resting heart rate (HRr) and changes in IOP after exercise.
Forty-one healthy volunteers between the ages of 19 and 25 years were recruited for the study. First, the resting (reference) values IOPr and HRr were measured after 30 min of resting time. Volunteers consequently performed 30 min of exercise on a bicycle ergometer. Intraocular pressure was remeasured immediately after the end of exercise (the relevant IOP change was denoted as ΔIOP0) and subsequently repeated 5, 10, 20, and 30 min after exercise.
A significant decrease in IOP compared with the resting value (post hoc Tukey honest significant difference test) was found immediately after exercise (p = 2 × 10) and 5 and 10 min after exercise (p = 2 × 10 and p = 3 × 10). Significant relationships were found between the change in IOP (ΔIOP0) and baseline IOP (IOPr) and between the baseline resting heart rate (HRr) and the change in IOP (ΔIOP0).
There was a significant IOP-lowering effect, which was persistent for 10 min after 30 min of exercise. The IOP change was dependent on the initial IOP reading and initial HR.
本研究的目的是评估在有明确体力消耗的正常健康个体中，适度运动前后的眼压（IOP）。本调查的第二个目的是确定静息眼压（IOPr）与其运动引起的变化之间的相关性，以及静息心率（HRr）与运动后眼压变化之间的关系。
招募了41名年龄在19至25岁之间的健康志愿者参与研究。首先，在休息30分钟后测量静息（参考）值IOPr和HRr。志愿者随后在自行车测力计上进行30分钟的运动。运动结束后立即重新测量眼压（相关的眼压变化记为ΔIOP0），随后在运动后5、10、20和30分钟重复测量。
与静息值相比，运动后立即（事后Tukey诚实显著差异检验）以及运动后5分钟和10分钟（p = 2×10和p = 3×10）发现眼压显著降低。在眼压变化（ΔIOP0）与基线眼压（IOPr）之间以及基线静息心率（HRr）与眼压变化（ΔIOP0）之间发现了显著关系。
运动30分钟后有显著的降低眼压效果，且在运动后持续10分钟。眼压变化取决于初始眼压读数和初始心率。
