High intensity aerobic exercise significantly reduced intraocular pressure in healthy young male adults.
This study sought to determine how aerobic exercise at various intensities affects intraocular pressure (IOP) in young adults.
A repeated measures design was adopted.
A group of 20 volunteers (mean age: 21.24±1.73 y) took part in this study.
IOP was measured with a tonometer (iCare TA01i, Icare Finland, Finland). Subjects completed 4 cycle ergometer sessions. During the first session, power was increased by 60 W every 3 minutes until exhaustion, corresponding to peak power. For the 3 following tests, each lasting 25 minutes, subjects exercised at intensities of 50%, 70%, and 85% of peak power, respectively, and measurements were taken every 5 minutes.
IOP, as determined using a tonometer, was the primary measure.
There was a significant reduction ( P <0.05) in IOP of both eyes during the 25 minutes high-intensity (85%) exercise test. There were also significant interactions between exercise durations and intensities. During high-intensity exercise, IOP, blood pressure, blood lactate, and the rating of perceived exertion were significantly related ( P <0.01).
These data show a significant reduction in IOP at high-intensity aerobic exercise, which may have implications for the management of ocular health.
高强度有氧运动显著降低了健康年轻男性成年人的眼内压。
本研究旨在确定不同强度的有氧运动如何影响年轻人的眼内压（IOP）。
采用重复测量设计。
一组 20 名志愿者（平均年龄：21.24±1.73 y）参与了这项研究。
使用眼压计（iCare TA01i，Icare Finland，芬兰）测量眼压。受试者完成了 4 次循环测力计测试。在第一次测试中，功率每 3 分钟增加 60 W，直到力竭，对应于最大功率。对于接下来的 3 次测试，每次持续 25 分钟，受试者分别以 50%、70%和 85%的最大功率进行运动，每 5 分钟测量一次。
使用眼压计测量的眼压是主要指标。
在 25 分钟的高强度（85%）运动测试中，双眼的眼压显著降低（P<0.05）。运动时间和强度之间也存在显著的相互作用。在高强度运动期间，眼压、血压、血乳酸和感知用力程度显著相关（P<0.01）。
这些数据表明，高强度有氧运动可显著降低眼内压，这可能对眼部健康管理具有重要意义。
