The present study was planned to investigate the relationship between the magnitude of intraocular pressure (IOP) reduction after short-duration exercise and the intensity, duration and quantity of exercise in healthy subjects. Twenty-five healthy, sedentary male of the same age group, performed exercises at the levels of 80%, 60%, and 40% maximum heart rate (HRmax) for 15 minutes, 80% HRmax for 7.5 minutes, 60% HRmax for 10 minutes, and 40% HRmax for 30 minutes. IOP was measured with the Goldmann applanation tonometer. The IOP reduction at 5 minutes after 15 minutes of exercising at 80% HRmax, 60% HRmax, and 40% HRmax were 4.7 +/- 0.9, 3.5 +/- 0.7, and 0.9 +/- 0.4 mmHg, respectively. At five minutes, after exercising 7.5 minutes at 80% HRmax, 10 minutes at 60% HRmax, and 30 minutes at 40% HRmax, IOP reduced by 4.5 +/- 0.7, 3.3 +/- 0.9, and 2.9 +/- 1.1 mmHg, respectively. This study concludes that intensity of exercise seems responsible for the magnitude of the initial IOP decrease after short-term exercise. Furthermore, it seems that other factors such as duration of exercise or quantity of exercise, blood pressures, body mass index are not related to the amount of the initial fall in IOP.
本研究旨在调查健康受试者短期运动后眼压（IOP）降低幅度与运动强度、持续时间和运动量之间的关系。25名同一年龄组的健康久坐男性，分别以最大心率（HRmax）的80%、60%和40%的水平进行15分钟运动，以80% HRmax进行7.5分钟运动，以60% HRmax进行10分钟运动，以40% HRmax进行30分钟运动。使用Goldmann压平眼压计测量眼压。在以80% HRmax、60% HRmax和40% HRmax进行15分钟运动后5分钟时，眼压降低分别为4.7±0.9、3.5±0.7和0.9±0.4 mmHg。在以80% HRmax进行7.5分钟运动、以60% HRmax进行10分钟运动和以40% HRmax进行30分钟运动后5分钟时，眼压分别降低了4.5±0.7、3.3±0.9和2.9±1.1 mmHg。本研究得出结论，运动强度似乎是短期运动后初始眼压降低幅度的原因。此外，运动持续时间或运动量、血压、体重指数等其他因素似乎与初始眼压下降幅度无关。
