OBJECTIVE: This study sought to determine how aerobic exercise at various intensities effects intraocular pressure (IOP) in young adults. DESIGN: A repeated measures design was adopted. PARTICIPANTS: A group of 20 volunteers (mean age: 21.24±1.73 y) took part in this study. METHODS: 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 min until exhaustion, corresponding to peak power. For the 3 following tests, each lasting 25 min, subjects exercised at intensities of 50%, 70%, and 85% of peak power, respectively, and measurements were taken every 5 min. MAIN OUTCOME MEASURES: IOP, as determined using a tonometer, was the primary measure. RESULTS: There was a significant reduction (P<0.05) in IOP of both eyes during the 25-min 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 (RPE) were significantly related (P<0.01). CONCLUSIONS: These data show a significant reduction in IOP at high-intensity aerobic exercise, which may have implications for management of ocular health.
